Systems Approach Can Improve Cancer Pain Management Based on research by Barbara A. Murphy, MD SAN DIEGO—A systems approach to pain and symptom management can boost the overall well-being of patients with cancer, according to Barbara A. Murphy, MD, a medical oncologist who works with a multidisciplinary healthcare team to improve patients’ quality of life (QOL) and ensure coordinated care.

Speaking at the Scripps Cancer Center’s 29th annual conference on clinical hematology and oncology, she said it is “a moral imperative” to alleviate suffering in cancer patients.

DENVER—Bone loss is a growing concern among breast cancer survivors, because aromatase inhibitors are increasingly being prescribed as adjunctive hormonal therapy for estrogen receptor–positive breast cancer. Research shows significant decline in bone mineral density (BMD) and increased risk of fracture among women who receive aromatase inhibitors. However, researchers are now reporting that bone loss can be prevented in breast cancer survivors undergoing hormonal therapy if secondary causes of bone loss (vita-

s this issue goes to press, heated debate continues about healthcare reform and the possible implications for oncology practice if the reforms are passed. But even without broader healthcare reform, actions being taken by the US Food and Drug Administration (FDA) could have an immediate impact on oncology practitioners and their patients. The FDA has announced the Safe Use Initiative, intended to reduce preventable adverse events due to abuse or misuse of prescription drugs. This initiative signals an expanding role of the agency. “We’re moving beyond our traditional role of regulator of the industry and reaching beyond to make sure we’re impacting use in the real world,” said Janet Woodcock, MD, director of the FDA’s Center for Drug Evaluation and Research at a news conference.

The FDA is also considering implementation of one of its Risk Evaluation and Mitigation Strategies (REMS) for opioids. These agents are mainstays of pain management in patients with cancer, and, although it is necessary to ensure that they are used safely and appropriately, it is also important that any restrictions on their use are not prohibitive and they remain available to patients who need them. As discussed in the article on pain management in this issue, however, good management of pain goes beyond drug therapy, and a multidisciplinary approach can improve symptom control and patients’ quality of life. Good bone health is also essential in maintaining a patient’s mobility and quality of life. New reports from the American Society for Bone and Mineral Research demonstrate the importance of preventing bone loss in patients with cancer and provide

reassurance that treatment with bisphosphonates does not appear to promote development of cancer, which some earlier reports had suggested. In addition to responsibilities to our patients, many of us are involved in practice management decisions and training of residents. Lisa Lohr provides excellent suggestions for designing and implementing a residency project. For pharmacists practicing in community cancer centers, Michele Woods continues her series providing suggestions on organizational issues and hardware and software requirements for setting up a clinic in this setting. We are planning for our third year of publication and look forward to hearing your views on healthcare reform and other issues of importance to pharmacists and other members of the cancer care team. ●

News Notes News Updates of Relevance to Everyday Oncology Practice ■ Metastatic Lobular Breast Cancer Tumor DNA Sequenced Canadian researchers, in an attempt to precisely characterize all somatic coding mutations that occur during the development and progression of an individual cancer, have sequenced all 3 billion letters in the DNA sequence of one estrogen receptor α–positive metastatic lobular breast cancer tumor. With the recent advances in next-generation sequencing, the researchers were able to sequence the genome in just weeks. They found 32 somatic nonsynonymous coding mutations in the metastatic tumor. On comparison with the patient’s primary tumor from 9 years prior, five of those mutations were prevalent, six were

present at lower frequencies, 19 were not present, and two were undetermined. The five prevalent mutations were not previously known to researchers as being involved in cancer, thus identifying avenues to pursue for the development of personalized medicines for patients (Nature. 2009;461:809-813). ■ PV-10 Compassionate Use Program Extended to United States PV-10, an investigational agent being developed as a therapeutic for a broad spectrum of cancers, is now available to patients under the US Food and Drug Administration’s compassionate use guidelines.

The Centers for Medicare & Medicaid Services recognizes the NCCN compendium as a mandated reference for oncology coverage policy. In January 2008, UnitedHealthcare began basing its benefit coverage for chemotherapy drugs used in outpatient settings on the compendium as well. The free access reflects the company’s ongoing commitment to ensuring physicians and patients have access to evidenced-based care. The access will also help save time by eliminating time spent on phone calls for coverage confirmation (UnitedHealthcare). ■ 2010 Medicare Physician Fee Schedule The Centers for Medicare & Medicaid Services (CMS) announced the final policies and payment rates for services rendered during the 2010 calendar year by practitioners who are paid under the Medicare Physician Fee Schedule (MPFS). In a success for radiation oncology, CMS will not implement its proposed 19% cut; instead radiation oncology payments will be reduced by only 5% over the next 4 years. CMS will also continue to use specialty supplemental survey data to determine practice expenses for medical oncology. In a statement, American Society of Clinical Oncology CEO Allen S. Lichter, MD, expressed: “We are deeply concerned that these cuts will continue to erode access to cancer care in the United States. ●

Viewpoint VIEWPOINT

How the US Government Rations Health Care The agency that would likely run the “public option� was slow to pay for implantable cardiac defibrillators.

P

resident Barack Obama deflects criticism that his health-care plan will bring on government rationing of medical care by arguing that insurance companies ration care. Everyone knows private payers limit access to some health care. But government does it in far more byzantine and arbitrary ways. Consider the $450 billion Medicare program. It provides a model for— indeed its bureaucracy could well end up running—the “public option� health plan that Mr. Obama wants to offer all Americans under the age of 65. In recent years, Medicare’s staff has been aggressively restricting coverage for costly treatments. Looking for ways to control spending on medical products— and preserve the illusory “trust fund� that pays Medicare claims—is what shapes the culture of the organization and motivates the agency’s staff. This often means limiting access to the costliest technologies. To do this Medicare relies on its rationing and pricing systems. National coverage decisions (NCDs) are assessments issued by Medicare’s medical staff that define who is eligible for new but often expensive treatments. Medicare then assigns medical products and procedures with

“codes� that determine which regulated category they fall into. Finally, price “schedules� are developed by Medicare’s staff each year to assign each unique code with its own updated payment rate. The process for getting a favorable code on a new product is a source of intense lobbying. It can make or break a technology. For a remote agency like Medicare, far removed from clinical practice, it’s easier to try and manage the use of a high-cost but specialty treatment than a much lower-cost but very widely used product. Yet cheaper, more commonly used products can still be mispriced and account for more total cost to the agency. For example, low-tech orthotic devices and other “durable medical equipment� are a known source of wasteful spending. These medical products often evade Medicare’s attention in favor of less used but more expensive items such as a biological cancer drug. Take the agency’s tortured decisions concerning the use of implantable defibrillators that jump-start stopped hearts during cardiac arrest. Medicare sharply restricted their use in the 1990s. Mounting research proved that the $30,000 devices could be saving many more lives. So in 2003 Medicare

adopted a novel theory to expand coverage to some, but not everyone, who needed one. The agency said only patients with certain measures on their electrocardiograms (called “wide QRS�) seemed to benefit. It was an easily measurable but ultimately imprecise way to allocate the devices. After another major study firmly refuted the QRS theory, Medicare expanded coverage again in 2005, potentially saving 2,500 additional lives according to a press release issued with that decision. That experience wasn’t unique. From 1999 to 2007, Medicare denied access in a third of the treatments it evaluated through its coverage process, taking an average of eight months to complete its reviews. When coverage was granted, in 85% of cases the treatments were restricted, usually to patients with more advanced illnesses. Medicare is lately increasing its use of the national coverage process and is becoming more tightfisted. Since 2008, according to my review of Medicare data, it conditioned access in 29% of its reviews and denied new or expanded coverage in fully 53% of cases. Medicare’s methods can also be arbitrary. Take the travails of the pharmaceutical company Sepracor and its drug Xopenex, an innovative respiratory medicine that competes with the chemically distinct and much cheaper generic albuterol. Both are inhaled aerosols used to treat asthma and chronic obstructive pulmonary disease. Xopenex has the same benefits as albuterol, but some believe fewer of its cardiac side effects. Medicare didn’t agree. The agency tried to make a “national coverage decision� on Xopenex but couldn’t come up with a clinical justification to limit the drug’s usage. So Medicare manipulated its payment process, saying it would pay Xopenex a price equivalent to the “least costly alternative� form of generic albuterol, 10 cents a treatment compared to about $2.50 for Xopenex. Then Medicare was sued by a patient, and a Federal court recently ruled the agency exceeded its authority. Medicare finally succeeded in reigning in the use of Xopenex with its coding system. By issuing Xopenex the same classification as generic albuterol, it was able to pay both products the same “blended� price—an average of the cost of each individual drug. That

lowered the price on Xopenex, but ironically increased what Medicare paid for the generics. It’s not a stretch to say that Medicare spent hundreds of cumulative man-hours focusing on Xopenex while other priorities languished. The question is why? There weren’t safety concerns. Xopenex may have been used in lieu of a cheaper alternative, but at peak Medicare sales of about $300 million it represented far less than one one-thousandth of the agency’s budget. Simply put, a few staffers inside Medicare were consumed with the drug and its higher price—revealing a process that is capricious and often disconnected from science. Worse still is how impenetrable these programs have become. Drug and device companies spend millions of dollars trying to influence Medicare decisions. The hundreds of consultants they hire to advise them typically command $20,000-a-month retainers. Formal patient and provider appeals to Medicare took an average of 21 months, according to a report issued in 2003 by the Government Accountability Office (using 2001 data), with delays in “administrative processing� due to “inefficiencies and incompatibility� of data systems eating up 70% of the time spent processing appeals. There’s nothing inherently wrong with a program like Medicare seeking value for taxpayers. But it shouldn’t make up the rules as it goes. When private plans ration care, patients can appeal directly to an insurer’s medical staff. Only a small fraction of Medicare’s denied claims—about 5%—are ever formally appealed because its process is so impenetrable. People can also switch insurers, and in many cases patients chose a policy because it matched their preferences in the first place. These options don’t exist in a government health program. � —Scott Gottlieb Dr. Gottlieb is a resident fellow at the American Enterprise Institute and a former senior official at the Centers for Medicare & Medicaid Services.

FOR A SUCCESSFUL CINV PREVENTION STRATEGY FROM THE FIRST CYCLE When patients experience acute chemotherapyyinduced nausea and vomiting (CINV) during their eir first cycle of chemotherapy, they may have an increased risk of CINV on subsequent days and in subsequent cycles.1-3 ALOXI®: A single IV dose lasts up to 5 days after MEC4,5* The only IV 5-HT3 antiemetic specifically approved for prevention of both acute and delayed CINV associated with MEC6* Can be used with multiple-day chemotherapy regimens mens6† * Moderately emetogenic chemotherapy. † Based on sNDA approval in August 2007, the restriction on repeated dosing of ALOXI (palonosetron HCl) injection within a 7-day interval was removed.

Indication ALOXI® (palonosetron HCl) injection 0.25 mg is indicated for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic chemotherapy, and acute nausea and vomiting associated with initial and repeat courses of highly emetogenic chemotherapy. Important Safety Information • ALOXI is contraindicated in patients known to have hypersensitivity to the drug or any of its components • Most commonly reported adverse reactions in chemotherapy-induced nausea and vomiting include headache (9%) and constipation (5%) Please see the following brief summary of prescribing information.

Continued from cover launch an assertive, proactive communication program and to manage dose requirements of opioids.

Improving QOL The holistic program used in her practice is committed to improving the patients’ QOL by addressing not only ALOXI® (palonosetron HCl) injection BRIEF SUMMARY OF PRESCRIBING INFORMATION INDICATIONS AND USAGE Chemotherapy-Induced Nausea and Vomiting ALOXI is indicated for: • Moderately emetogenic cancer chemotherapy – prevention of acute and delayed nausea and vomiting associated with initial and repeat courses • Highly emetogenic cancer chemotherapy – prevention of acute nausea and vomiting associated with initial and repeat courses DOSAGE AND ADMINISTRATION Recommended Dosing Chemotherapy-Induced Nausea and Vomiting Dosage for Adults - a single 0.25 mg I.V. dose administered over 30 seconds. Dosing should occur approximately 30 minutes before the start of chemotherapy. Instructions for I.V. Administration ALOXI is supplied ready for intravenous injection. ALOXI should not be mixed with other drugs. Flush the infusion line with normal saline before and after administration of ALOXI. Parenteral drug products should be inspected visually for particulate matter and discoloration before administration, whenever solution and container permit. CONTRAINDICATIONS ALOXI is contraindicated in patients known to have hypersensitivity to the drug or any of its components. [see Adverse Reactions (6) in full prescribing information ] WARNINGS AND PRECAUTIONS Hypersensitivity Hypersensitivity reactions may occur in patients who have exhibited hypersensitivity to other 5-HT 3 receptor antagonists. ADVERSE REACTIONS Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates reported in practice. In clinical trials for the prevention of nausea and vomiting induced by moderately or highly emetogenic chemotherapy, 1374 adult patients received palonosetron. Adverse reactions were similar in frequency and severity with ALOXI and ondansetron or dolasetron. Following is a listing of all adverse reactions reported by ≥ 2% of patients in these trials (Table 1). Table 1: Adverse Reactions from ChemotherapyInduced Nausea and Vomiting Studies ≥ 2% in any Treatment Group ALOXI Ondansetron Dolasetron Event 0.25 mg 32 mg I.V. 100 mg I.V.

One patient received a 10 mcg/kg oral dose in a postoperative nausea and vomiting study and one healthy subject received a 0.75 mg I.V. dose in a pharmacokinetic study. In clinical trials, the following infrequently reported adverse reactions, assessed by investigators as treatment-related or causality unknown, occurred following administration of ALOXI to adult patients receiving concomitant cancer chemotherapy: Cardiovascular: 1%: non-sustained tachycardia, bradycardia, hypotension, < 1%: hypertension, myocardial ischemia, extrasystoles, sinus tachycardia, sinus arrhythmia, supraventricular extrasystoles and QT prolongation. In many cases, the relationship to ALOXI was unclear. Dermatological: < 1%: allergic dermatitis, rash. Hearing and Vision: < 1%: motion sickness, tinnitus, eye irritation and amblyopia. Gastrointestinal System: 1%: diarrhea, < 1%: dyspepsia, abdominal pain, dry mouth, hiccups and flatulence.

their physical cancer issues, but their emotional and spiritual issues as well. “I’m not just talking about drugs,” she said. “Pain is a problem, and we have had the tools to deal with that part of the problem.” The purpose of Murphy’s oncology supportive care program, she said, is to: General: 1%: weakness, < 1%: fatigue, fever, hot flash, flu-like syndrome. Liver: < 1%: transient, asymptomatic increases in AST and/or ALT and bilirubin. These changes occurred predominantly in patients receiving highly emetogenic chemotherapy. Metabolic: 1%: hyperkalemia, < 1%: electrolyte fluctuations, hyperglycemia, metabolic acidosis, glycosuria, appetite decrease, anorexia. Musculoskeletal: < 1%: arthralgia. Nervous System: 1%: dizziness, < 1%: somnolence, insomnia, hypersomnia, paresthesia. Psychiatric: 1%: anxiety, < 1%: euphoric mood. Urinary System: < 1%: urinary retention. Vascular: < 1%: vein discoloration, vein distention. Postmarketing Experience The following adverse reactions have been identified during postapproval use of ALOXI. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Very rare cases (<1/10,000) of hypersensitivity reactions and injection site reactions (burning, induration, discomfort and pain) were reported from postmarketing experience of ALOXI 0.25 mg in the prevention of chemotherapy-induced nausea and vomiting. DRUG INTERACTIONS Palonosetron is eliminated from the body through both renal excretion and metabolic pathways with the latter mediated via multiple CYP enzymes. Further in vitro studies indicated that palonosetron is not an inhibitor of CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2D6, CYP2E1 and CYP3A4/5 (CYP2C19 was not investigated) nor does it induce the activity of CYP1A2, CYP2D6, or CYP3A4/5. Therefore, the potential for clinically significant drug interactions with palonosetron appears to be low. Coadministration of 0.25 mg I.V. palonosetron and 20 mg I.V. dexamethasone in healthy subjects revealed no pharmacokinetic drug-interactions between palonosetron and dexamethasone. In an interaction study in healthy subjects where palonosetron 0.25 mg (I.V. bolus) was administered on day 1 and oral aprepitant for 3 days (125 mg/80 mg/80 mg), the pharmacokinetics of palonosetron were not significantly altered (AUC: no change, Cmax: 15% increase). A study in healthy volunteers involving single-dose I.V. palonosetron (0.75 mg) and steady state oral metoclopramide (10 mg four times daily) demonstrated no significant pharmacokinetic interaction. In controlled clinical trials, ALOXI injection has been safely administered with corticosteroids, analgesics, antiemetics/antinauseants, antispasmodics and anticholinergic agents. Palonosetron did not inhibit the antitumor activity of the five chemotherapeutic agents tested (cisplatin, cyclophosphamide, cytarabine, doxorubicin and mitomycin C) in murine tumor models. USE IN SPECIFIC POPULATIONS Pregnancy Teratogenic Effects: Category B Teratology studies have been performed in rats at oral doses up to 60 mg/kg/day (1894 times the recommended human intravenous dose based on body surface area) and rabbits at oral doses up to 60 mg/ kg/day (3789 times the recommended human intravenous dose based on body surface area) and have revealed no evidence of impaired fertility or harm to the fetus due to palonosetron. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, palonosetron should be used during pregnancy only if clearly needed. Labor and Delivery Palonosetron has not been administered to patients undergoing labor and delivery, so its effects on the mother or child are unknown. Nursing Mothers It is not known whether palonosetron is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants and the potential for tumorigenicity shown for palonosetron in the rat carcinogenicity study, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

• Improve patients’ overall wellbeing and thus the QOL • Enhance symptom control and functional outcome • Modify health behaviors. The global construct, Murphy said, includes patients’ perceptions of wellbeing, as influenced by their experiences, Pediatric Use Safety and effectiveness in patients below the age of 18 years have not been established. Geriatric Use Population pharmacokinetics analysis did not reveal any differences in palonosetron pharmacokinetics between cancer patients ≥ 65 years of age and younger patients (18 to 64 years). Of the 1374 adult cancer patients in clinical studies of palonosetron, 316 (23%) were ≥ 65 years old, while 71 (5%) were ≥ 75 years old. No overall differences in safety or effectiveness were observed between these subjects and the younger subjects, but greater sensitivity in some older individuals cannot be ruled out. No dose adjustment or special monitoring are required for geriatric patients. Of the 1520 adult patients in ALOXI PONV clinical studies, 73 (5%) were ≥65 years old. No overall differences in safety were observed between older and younger subjects in these studies, though the possibility of heightened sensitivity in some older individuals cannot be excluded. No differences in efficacy were observed in geriatric patients for the CINV indication and none are expected for geriatric PONV patients. However, ALOXI efficacy in geriatric patients has not been adequately evaluated. Renal Impairment Mild to moderate renal impairment does not significantly affect palonosetron pharmacokinetic parameters. Total systemic exposure increased by approximately 28% in severe renal impairment relative to healthy subjects. Dosage adjustment is not necessary in patients with any degree of renal impairment. Hepatic Impairment Hepatic impairment does not significantly affect total body clearance of palonosetron compared to the healthy subjects. Dosage adjustment is not necessary in patients with any degree of hepatic impairment. Race Intravenous palonosetron pharmacokinetics was characterized in twenty-four healthy Japanese subjects over the dose range of 3 – 90 mcg/kg. Total body clearance was 25% higher in Japanese subjects compared to Whites, however, no dose adjustment is required. The pharmacokinetics of palonosetron in Blacks has not been adequately characterized. OVERDOSAGE There is no known antidote to ALOXI. Overdose should be managed with supportive care. Fifty adult cancer patients were administered palonosetron at a dose of 90 mcg/kg (equivalent to 6 mg fixed dose) as part of a dose ranging study. This is approximately 25 times the recommended dose of 0.25 mg. This dose group had a similar incidence of adverse events compared to the other dose groups and no dose response effects were observed. Dialysis studies have not been performed, however, due to the large volume of distribution, dialysis is unlikely to be an effective treatment for palonosetron overdose. A single intravenous dose of palonosetron at 30 mg/kg (947 and 474 times the human dose for rats and mice, respectively, based on body surface area) was lethal to rats and mice. The major signs of toxicity were convulsions, gasping, pallor, cyanosis and collapse.

points of view, expectations, and beliefs.1 She reminded clinicians that healthrelated issues are only one factor when considering QOL. Commonly assessed QOL domains include well-being on several fronts: physical, functional, social, emotional, spiritual, and financial.

Patients underreport psychological distress Murphy said numerous studies use self-report questionnaires to conclude that cancer patients do not have a lower QOL than healthy people. Murphy quoted the work of Breetvelt and Van Dam2 who wrote about the so-called response shift: “Under the influence of a highly significant life event, such as getting a life-threatening disease…there will be a concurrent change in the internalized standard on which the patient bases their perceptions.” In other words, patients in these studies were underreporting their psychological distress; on their own, they had made the decision to move the bar. Breetvelt and Van Dam warned that the true nature of cancer and the resulting decrease in QOL could be “obscured totally.” They said these “I’m OK” studies were in contrast with other research that documented the de rigueur experience of treating physicians, nurses, and other caretakers. They advised physicians not to put a lot of stock in questionnaires. Education of patients, physicians, and their staffs: what works? Murphy said patient education can help overcome barriers to improved QOL. “But patient education by itself will not improve their outcome,” she said. Barrier reduction can have more of an effect on the outcome if it focuses on such end points as knowledge, attitudes, practice patterns, and pain control, but, in studies, it has not been sufficient by itself. “We hoped education would improve patient outcome, but you can change knowledge and attitude and that has not made a significant difference in the outcome,” said Murphy. A study by Wells and associates found that a pain education program could improve knowledge and beliefs of the patient and their primary caregiver, but that continued access to pain-related information did not affect long-term pain outcomes.3 Moving beyond education “We need to move beyond education—but where next?” asked Murphy. “More interventions are needed that can be easily adopted by clinicians in various settings.” She suggested a “pain hotline” where patients could communicate their

A model for adequate pain control would include patient reporting of pain levels, an assessment titration communication, and the physician’s cooperation. pain to their providers. “This had been used in a postoperative setting where it was found to be effective, but when studied in the oncology setting, it was not.” Murphy suggested that a model for adequate pain control would include patient reporting of pain levels, an assessment titration communication, and the physician’s cooperation. Patients, she suggested, could keep a pain diary and a brief pain index. She noted her current investigation of a nurse-managed narcotic-titration drugorder sheet,4 as a way to improve pain control. This phase 3 study is sponsored by the National Cancer Institute.

Critical steps for adequate pain outcome Murphy listed the critical steps that should be considered for adequate pain outcome: 1. Patient report of pain (and medical staff recognition of problem) 2. Assessment of pain by the provider 3. Pain treatment plan 4. Review of plan with patient 5. Document assessment and plan

6. Patient follows treatment plan. To elucidate the critical steps in a specific plan, Murphy discussed a study by Cleeland and colleagues, who examined a computerized telephone monitoring and alert system (with an interactive voice-response system) that alerted clinic staff via e-mail when cancer patient pain levels exceeded a specified threshold.5 Telephone calls primarily reinforced the patient’s use of prescribed medication, provided information for the management of symptoms, or addressed the need for and arranged a change of medication. The researchers found that this method reduced symptom severity and lowered symptomrelated interference for the monitored group compared with the control group. “The e-mail alert would go to a nurse, and she could react; we found this phone call intervention worked really well,” said Murphy.

VHA study An earlier report by Cleeland and associates described a joint collaborative (Veterans Health Administration [VHA] and Institute for Healthcare Improve-

ment) that used a rapid-cycle improvement model to improve pain management within the VHA Health System. Each patient–healthcare provider dyad worked within a system to affect a better outcome.6 The study’s goals were to improve delivery of pain management to VHA patients and to compare team process and patient report data on key goals from selected study units; 70 teams from 22 Veterans Integrated Service Networks participated. Findings were that the number of patients experiencing moderate or severe pain on study units dropped from 24% to 17% while pain assessment increased from 75% to 85%; pain-care plans for patients with mild pain increased from 58% to 78%; and the number of patients provided pain education increased from 35% to 62%. “This study highlights the critical issue of patients needing a plan of care,” said Murphy.

IT could address complex problem Murphy said that combining electronic medical records with a systems approach gives data at a glance. The two basic components of a systems approach —elements and processes—can be applied in the medical records setting. She explained it this way: In a car, the dashboard gives the driver a glimpse of all the information needed to make decisions while operating the vehicle. Dashboards in IT are essentially the

same. “You can look at the display and say, ‘What am I doing well, or not well?’ It allows you to search databases and identify outcome issues at the patient level, the clinic level, and the provider level,” said Murphy, who pointed out that, based on the patient’s report of pain, the provider could match the level of pain to the regimen prescribed. She said that a lot of data could be organized with this system so that providers could offer adequate pain control for the many stakeholders. She added, “Pain control is complex, but using information systems and technology may hold the key to this complex problem.” ● —Kristina Rebelo

InternatIonal oncology news Reports from International Meetings and Researchers Intranasal Fentanyl Is Superior to Oral Formulation for Breakthrough Cancer Pain LISBON, PORTUGAL—Intranasal fentanyl spray (INFS) confers meaningful relief of breakthrough cancer pain faster than transmucosal fentanyl citrate (OTFC) in most patients, according to data released at the 6th Congress of the European Federation of Chapters of the International Association of the Study of Pain. Sebastiano Mercadante, MD, director of the Palliative Care Unit at La Maddalena Hospital in Palermo, Italy, presented results in 139 patients who had been randomized to treatment with INFS or OTFC titrated to doses of 50, 100, or 200 µg and 200, 400, 600, 800, 1200, or 1600 µg fentanyl, respectively. Trial participants were adult inpatients or outpatients with cancer who

November/December 2009

were experiencing at least three episodes of weekly breakthrough cancer pain but no more than four daily episodes. All patients were using a stable chronic opioid treatment for background pain. Overall, 25% of episodes showed meaningful pain relief at 5 minutes after treatment with INFS versus 7% with OTFC. In addition, 51% of INFS-treated patients had meaningful pain relief at 10 minutes versus 24% with OTFC. The analysis also revealed that patients found INFS easier to administer. Overall, 90% of patients said that INFS was “easy” or “very easy” to use versus 40% for OTFC. “The pharmacodynamic profile of INFS fits very closely with the temporal characteristics of breakthrough cancer pain,” Mercadante observed. The study also found that INFS was well tolerated.

More than 90% of patients with cancer pain experience breakthrough pain, which is inadequately controlled in two thirds of cases, Mercadante pointed out.

Increased Public Awareness of Head and Neck Cancer Needed AMSTERDAM, THE NETHERLANDS—New data demonstrate a lack of knowledge among Europeans about the risk factors and symptoms of head and neck cancer. The findings were reported by researchers who analyzed responses to online questionnaires completed by about 7500 people in France, Denmark, Italy, the Netherlands, Spain, Sweden, and the United Kingdom. The “About Face” survey revealed that only 23% of participants were aware of the term “head and neck can-

cer,” and less than half were able to correctly identify symptoms of head and neck cancer. Sixty percent of respondents thought that brain tumors are a type of head and neck cancer. Most participants knew that there is a link between head and neck cancer and smoking or high alcohol intake, but few patients knew of the role of the human papilloma virus (HPV) infection or excessive sun exposure in disease etiology. “Efforts need to address the gaps in knowledge among the general public in head and neck cancer,” according to C. Rene Leemans, MD, co-director of the VUMC Cancer Centre in Amsterdam, the Netherlands. This is particularly important since knowledge gaps can lead to a delay in seeing a physician, which translates into a delay in diagnosis, he added. ● —Jill Stein

Bone Loss in Breast Cancer Patients CONFERENCE NEWS

Continued from cover min D deficiency, idiopathic hypercalciuria, primary hyperparathyroidism, hypocalciuria, and normocalcemic hyperparathyroidism) are corrected and bisphosphonate therapy is used appropriately. Primary causes of osteoporosis are menopause and aging. Secondary causes are diseases or conditions that exacerbate bone loss. “Doctors evaluating breast cancer patients for possible bone loss should look further than cancer drugs,” said Pauline Camacho, MD, an associate professor of medicine at Loyola University School of Medicine, Chicago. It is well documented that aromatase inhibitors can decrease BMD and increase the risk of fractures in postmenopausal women. These medications can decrease the body’s production of estrogen. Although estrogen feeds cancer, the hormone also protects against osteoporosis. Camacho and colleagues reviewed charts of 81 consecutive breast cancer patients who were referred for treatment or prevention of osteoporosis. The researchers found that 51 patients had secondary causes of bone loss, including vitamin D deficiency (65%), excessive calcium excretion in urine (16%), or an overactive parathyroid gland (13%). Thirty patients did not have secondary causes of bone loss. All the patients received similar treatment with osteoporosis medications, such as alendronate and ibandronate. Women with secondary bone loss, however, also received additional treatments. For example, vitamin D deficiency was treated with prescription doses of vitamin D supplements, and excessive calcium excretion was treated with a diuretic. After 1 year, the breast cancer patients with secondary causes of bone loss had stable BMD in their spines and necks. BMD improved in the breast cancer patients who did not have secondary causes of bone loss. BMD is the amount of calcium and other minerals packed into a segment of bone and it predicts osteoporosis. Camacho said the study demonstrated that bone loss “can be prevented in women undergoing hormonal therapy if secondary causes of bone loss are corrected and bisphosphonate osteoporosis drugs are appropriately used.” She said the mean age of the women with secondary causes of bone loss was 58 years, and the mean age of the women without secondary causes of bone loss was 63 years. These study findings, which were presented at the 31st annual meeting of the American Society for Bone and Mineral Research, suggest that healthcare providers should discuss the importance of treating secondary causes of bone loss with women undergoing

breast cancer therapy. “This study is good news for breast cancer survivors, because they are worried about their bones and so are their oncologists. We showed that with proper workup and appropriate treatment they do quite well in terms of bone health. So

our findings are quite reassuring,” said Camacho in an interview with The Oncology Pharmacist. “I think the most important take-home point here is that aromatase inhibitors are being used increasingly in breast cancer patients and so these patients need to be thoroughly

evaluated and evaluated for secondary causes of bone loss, such as calcium deficiency. We found vitamin D deficiency was the most common problem. We saw it in 65% of the patients.” —John Schieszer

ERBITUX + RT: 26% reduction in Risk of Death from SCCHN1,2

Important Safety Information Including Boxed WARNINGS Infusion Reactions I Grade 3/4 infusion reactions occurred in approximately 3% of patients receiving ERBITUX® (cetuximab) in clinical trials, with fatal outcome reported in less than 1 in 1000 — Serious infusion reactions, requiring medical intervention and immediate, permanent discontinuation of ERBITUX, included rapid onset of airway obstruction (bronchospasm, stridor, hoarseness), hypotension, shock, loss of consciousness, myocardial infarction, and/or cardiac arrest — Immediately interrupt and permanently discontinue ERBITUX infusions for serious infusion reactions I Most (90%) of the severe infusion reactions were associated with the first infusion of ERBITUX despite premedication with antihistamines — Caution must be exercised with every ERBITUX infusion, as there were patients who experienced their first severe infusion reaction during later infusions — Monitor patients for 1 hour following ERBITUX infusions in a setting with resuscitation equipment and other agents necessary to treat anaphylaxis (eg, epinephrine, corticosteroids, intravenous antihistamines, bronchodilators, and oxygen). Longer observation periods may be required in patients who require treatment for infusion reactions Cardiopulmonary Arrest I Cardiopulmonary arrest and/or sudden death occurred in 4 (2%) of 208 patients with squamous cell carcinoma of the head and neck treated with radiation therapy and ERBITUX, as compared to none of 212 patients treated with radiation therapy alone. Fatal events occurred within 1 to 43 days after the last ERBITUX treatment — Carefully consider the use of ERBITUX in combination with radiation therapy in head and neck cancer patients with a history of coronary artery disease, congestive heart failure or arrhythmias in light of these risks — Closely monitor serum electrolytes including serum magnesium, potassium, and calcium during and after ERBITUX therapy Pulmonary Toxicity I Interstitial lung disease (ILD), which was fatal in one case, occurred in 4 of 1570 (<0.5%) patients receiving ERBITUX in clinical trials. Interrupt ERBITUX for acute onset or worsening of pulmonary symptoms. Permanently discontinue ERBITUX where ILD is confirmed Dermatologic Toxicities I In clinical studies of ERBITUX, dermatologic toxicities, including acneform rash, skin drying and fissuring, paronychial inflammation, infectious sequelae (eg, S. aureus sepsis, abscess formation, cellulitis, blepharitis, conjunctivitis, keratitis, cheilitis), and hypertrichosis, occurred in patients receiving ERBITUX therapy. Acneform rash occurred in 76-88% of 1373 patients receiving ERBITUX in clinical trials. Severe acneform rash occurred in 1-17% of patients — Acneform rash usually developed within the first two weeks of therapy and resolved in a majority of the patients after cessation of treatment, although in nearly half, the event continued beyond 28 days — Monitor patients receiving ERBITUX for dermatologic toxicities and infectious sequelae — Sun exposure may exacerbate these effects ERBITUX Plus Radiation Therapy and Cisplatin I The safety of ERBITUX in combination with radiation therapy and cisplatin has not been established — Death and serious cardiotoxicity were observed in a single-arm trial with ERBITUX, radiation therapy, and cisplatin (100 mg/m2) in patients with locally advanced squamous cell carcinoma of the head and neck — Two of 21 patients died, one as a result of pneumonia and one of an unknown cause — Four patients discontinued treatment due to adverse events. Two of these discontinuations were due to cardiac events

No Link Found between Cancer and Bisphosphonate Use DENVER—There appears to be no relationship between the use of bisphosphonates and the development of cancer, according to researchers at Columbia University College of Physicians and Surgeons.

A letter to the editor in the January 1, 2009, issue of the New England Journal of Medicine cited reports of esophageal cancer following treatment with alendronate as well as alendronate combined with other oral bis-

phosphonates. Since then, controversy has surrounded this issue. “We need to rectify this issue. There is no relationship between the use of bisphosphonates and esophageal cancer,” said John Bilezikian, MD, professor of

Electrolyte Depletion I Hypomagnesemia occurred in 55% (199/365) of patients receiving ERBITUX® (cetuximab) and was severe (NCI CTC grades 3 & 4) in 6-17%. The onset of hypomagnesemia and accompanying electrolyte abnormalities occurred days to months after initiation of ERBITUX therapy — Monitor patients periodically for hypomagnesemia, hypocalcemia and hypokalemia, during, and for at least 8 weeks following the completion of, ERBITUX therapy — Replete electrolytes as necessary Late Radiation Toxicities I The overall incidence of late radiation toxicities (any grade) was higher with ERBITUX in combination with radiation therapy compared with radiation therapy alone. The following sites were affected: salivary glands (65%/56%), larynx (52%/36%), subcutaneous tissue (49%/45%), mucous membranes (48%/39%), esophagus (44%/35%), and skin (42%/33%) in the ERBITUX and radiation versus radiation alone arms, respectively — The incidence of grade 3 or 4 late radiation toxicities were similar between the radiation therapy alone and the ERBITUX plus radiation therapy arms Pregnancy I In women of childbearing potential, appropriate contraceptive measures must be used during treatment with ERBITUX and for 6 months following the last dose of ERBITUX. ERBITUX may be transmitted from the mother to the developing fetus, and has the potential to cause fetal harm when administered to pregnant women. ERBITUX should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus Adverse Events I The most serious adverse reactions associated with ERBITUX across all studies were infusion reactions, cardiopulmonary arrest, dermatologic toxicity and radiation dermatitis, sepsis, renal failure, interstitial lung disease, and pulmonary embolus I The most common adverse reactions associated with ERBITUX (incidence ≥25%) are cutaneous adverse reactions (including rash, pruritus, and nail changes), headache, diarrhea, and infection I The most frequent adverse events seen in patients with carcinomas of the head and neck receiving ERBITUX in combination with radiation therapy (n=208) versus radiation alone (n=212) (incidence ≥50%) were acneform rash (87%/10%), radiation dermatitis (86%/90%), weight loss (84%/72%), and asthenia (56%/49%). The most common grade 3/4 adverse events for ERBITUX in combination with radiation therapy (≥10%) included: radiation dermatitis (23%), acneform rash (17%), and weight loss (11%) For more information, please visit www.ERBITUX.com or call 1-888-ERBITUX (372-4889).

Continued from page 9 Society for Bone and Mineral Research, Bilezikian and his colleagues examined clinical and postmarketing data regarding risedronate. This agent has been studied in placebo-controlled phase 3 trials for up to 3 years and in more than 19,000 patients. Risedronate has also

been studied in active-controlled studies with 4000 additional patients. Patients in the placebo-controlled studies were randomized to receive risedronate 2.5 mg daily (N = 4998), risedronate 5 mg daily (N = 5395), or placebo daily (N = 5363). The inci-

dence of esophageal cancer in these combined risedronate studies was 0.04% (two patients) in the 2.5-mg group, 0.02% (one patient) in the 5mg group, and 0.04% (two patients) in the placebo group. Overall, the researchers found that

ERBITUX® (cetuximab) Solution for intravenous infusion Brief Summary of Prescribing Information. For complete prescribing information consult official package insert. WARNING: SERIOUS INFUSION REACTIONS and CARDIOPULMONARY ARREST Infusion Reactions: Serious infusion reactions occurred with the administration of Erbitux in approximately 3% of patients in clinical trials, with fatal outcome reported in less than 1 in 1000. [See Warnings and Precautions and Adverse Reactions.] Immediately interrupt and permanently discontinue Erbitux infusion for serious infusion reactions. [See Warnings and Precautions and Dosage and Administration (2.4) in Full Prescribing Information.] Cardiopulmonary Arrest: Cardiopulmonary arrest and/or sudden death occurred in 2% of 208 patients with squamous cell carcinoma of the head and neck treated with radiation therapy and Erbitux. Closely monitor serum electrolytes, including serum magnesium, potassium, and calcium, during and after Erbitux. [See Warnings and Precautions.] INDICATIONS AND USAGE Squamous Cell Carcinoma of the Head and Neck (SCCHN) Erbitux® (cetuximab) is indicated in combination with radiation therapy for the initial treatment of locally or regionally advanced squamous cell carcinoma of the head and neck. [See Clinical Studies (14.1) in Full Prescribing Information.] Erbitux, as a single agent, is indicated for the treatment of patients with recurrent or metastatic squamous cell carcinoma of the head and neck for whom prior platinum-based therapy has failed. [See Clinical Studies (14.1) in Full Prescribing Information.] Colorectal Cancer Erbitux, as a single agent, is indicated for the treatment of epidermal growth factor receptor (EGFR)-expressing metastatic colorectal cancer after failure of both irinotecan- and oxaliplatin-based regimens. Erbitux, as a single agent, is also indicated for the treatment of EGFR-expressing metastatic colorectal cancer in patients who are intolerant to irinotecan-based regimens. [See Clinical Studies (14.2) in Full Prescribing Information and Warnings and Precautions.] Erbitux, in combination with irinotecan, is indicated for the treatment of EGFR-expressing metastatic colorectal carcinoma in patients who are refractory to irinotecan-based chemotherapy. The effectiveness of Erbitux in combination with irinotecan is based on objective response rates. Currently, no data are available that demonstrate an improvement in disease-related symptoms or increased survival with Erbitux in combination with irinotecan for the treatment of EGFR-expressing, metastatic colorectal carcinoma. [See Clinical Studies (14.2) in Full Prescribing Information and Warnings and Precautions.] Retrospective subset analyses of metastatic or advanced colorectal cancer trials have not shown a treatment benefit for Erbitux in patients whose tumors had KRAS mutations in codon 12 or 13. Use of Erbitux is not recommended for the treatment of colorectal cancer with these mutations [see Clinical Studies (14.2) and Clinical Pharmacology (12.1) in Full Prescribing Information]. CONTRAINDICATIONS None. WARNINGS AND PRECAUTIONS Infusion Reactions Serious infusion reactions, requiring medical intervention and immediate, permanent discontinuation of Erbitux, included rapid onset of airway obstruction (bronchospasm, stridor, hoarseness), hypotension, shock, loss of consciousness, myocardial infarction, and/or cardiac arrest. Severe (NCI CTC Grades 3 and 4) infusion reactions occurred in 2–5% of 1373 patients in clinical trials, with fatal outcome in 1 patient. Approximately 90% of severe infusion reactions occurred with the first infusion despite premedication with antihistamines. Monitor patients for 1 hour following Erbitux infusions in a setting with resuscitation equipment and other agents necessary to treat anaphylaxis (eg, epinephrine, corticosteroids, intravenous antihistamines, bronchodilators, and oxygen). Monitor longer to confirm resolution of the event in patients requiring treatment for infusion reactions. Immediately and permanently discontinue Erbitux in patients with serious infusion reactions. [See Boxed Warning and Dosage and Administration (2.4) in Full Prescribing Information.] Cardiopulmonary Arrest Cardiopulmonary arrest and/or sudden death occurred in 4 (2%) of 208 patients treated with radiation therapy and Erbitux as compared to none of 212 patients treated with radiation therapy alone in a randomized, controlled trial in patients with SCCHN. Three patients with prior history of coronary artery disease died at home, with myocardial infarction as the presumed cause of death. One of these patients had arrhythmia and one had congestive heart failure. Death occurred 27, 32, and 43 days after the last dose of Erbitux. One patient with no prior history of coronary artery disease died one day after the last dose of Erbitux. Carefully consider use of Erbitux in combination with radiation therapy in head and neck cancer patients with a history of coronary artery disease, congestive heart failure, or arrhythmias in light of these risks. Closely monitor serum electrolytes, including serum magnesium, potassium, and calcium, during and after Erbitux. [See Boxed Warning and Warnings and Precautions.] Pulmonary Toxicity Interstitial lung disease (ILD), including 1 fatality, occurred in 4 of 1570 (<0.5%) patients receiving Erbitux in clinical trials. Interrupt Erbitux for acute onset or worsening of pulmonary symptoms. Permanently discontinue Erbitux for confirmed ILD. Dermatologic Toxicity Dermatologic toxicities, including acneform rash, skin drying and fissuring, paronychial inflammation, infectious sequelae (for example S. aureus sepsis, abscess formation, cellulitis, blepharitis, conjunctivitis, keratitis, cheilitis), and hypertrichosis occurred in patients receiving Erbitux therapy. Acneform rash occurred in 76–88% of 1373 patients receiving Erbitux in clinical trials. Severe acneform rash occurred in 1–17% of patients. Acneform rash usually developed within the first two weeks of therapy and resolved in a majority of the patients after cessation of treatment, although in nearly half, the event continued beyond 28 days. Monitor patients receiving Erbitux for dermatologic toxicities and infectious sequelae. Instruct patients to limit sun exposure during Erbitux therapy. [See Dose Modifications (2.4) in Full Prescribing Information.] Use of Erbitux in Combination With Radiation and Cisplatin The safety of Erbitux in combination with radiation therapy and cisplatin has not been established. Death and serious cardiotoxicity were observed in a single-arm trial with Erbitux, radiation therapy, and cisplatin (100 mg/m2) in patients with locally advanced SCCHN. Two of 21 patients died, one as a result of pneumonia and one of an unknown cause. Four patients discontinued treatment due to adverse events. Two of these discontinuations were due to cardiac events. Hypomagnesemia and Electrolyte Abnormalities In patients evaluated during clinical trials, hypomagnesemia occurred in 55% of patients (199/365) receiving Erbitux and was severe (NCI CTC Grades 3 and 4) in 6–17%. The onset of hypomagnesemia and accompanying electrolyte abnormalities occurred days to months after initiation of Erbitux. Periodically monitor patients for hypomagnesemia, hypocalcemia, and hypokalemia, during and for at least 8 weeks following the completion of Erbitux. Replete electrolytes as necessary.

Epidermal Growth Factor Receptor (EGFR) Expression and Response Because expression of EGFR has been detected in nearly all SCCHN tumor specimens, patients enrolled in the head and neck cancer clinical studies were not required to have immunohistochemical evidence of EGFR tumor expression prior to study entry. Patients enrolled in the colorectal cancer clinical studies were required to have immunohistochemical evidence of EGFR tumor expression. Primary tumor or tumor from a metastatic site was tested with the DakoCytomation EGFR pharmDx™ test kit. Specimens were scored based on the percentage of cells expressing EGFR and intensity (barely/faint, weak-to-moderate, and strong). Response rate did not correlate with either the percentage of positive cells or the intensity of EGFR expression. ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the label: • Infusion reactions [See Boxed Warning and Warnings and Precautions.] • Cardiopulmonary arrest [See Boxed Warning and Warnings and Precautions.] • Pulmonary toxicity [See Warnings and Precautions.] • Dermatologic toxicity [See Warnings and Precautions.] • Hypomagnesemia and Electrolyte Abnormalities [See Warnings and Precautions.] The most common adverse reactions with Erbitux (cetuximab) (incidence ≥25%) are cutaneous adverse reactions (including rash, pruritus, and nail changes), headache, diarrhea, and infection. The most serious adverse reactions with Erbitux are infusion reactions, cardiopulmonary arrest, dermatologic toxicity and radiation dermatitis, sepsis, renal failure, interstitial lung disease, and pulmonary embolus. Across all studies, Erbitux was discontinued in 3–10% of patients because of adverse reactions. Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data below reflect exposure to Erbitux in 1373 patients with colorectal cancer or SCCHN in randomized Phase 3 (Studies 1 and 3) or Phase 2 (Studies 2 and 4) trials treated at the recommended dose and schedule for a median of 7 to 14 weeks. [See Clinical Studies (14) in Full Prescribing Information.] Infusion reactions: Infusion reactions, which included pyrexia, chills, rigors, dyspnea, bronchospasm, angioedema, urticaria, hypertension, and hypotension occurred in 15–21% of patients across studies. Grades 3 and 4 infusion reactions occurred in 2–5% of patients; infusion reactions were fatal in 1 patient. Infections: The incidence of infection was variable across studies, ranging from 13–35%. Sepsis occurred in 1–4% of patients. Renal: Renal failure occurred in 1% of patients with colorectal cancer. Squamous Cell Carcinoma of the Head and Neck Table 1 contains selected adverse events in 420 patients receiving radiation therapy either alone or with Erbitux for locally or regionally advanced SCCHN in Study 1. Erbitux was administered at the recommended dose and schedule (400 mg/m2 initial dose, followed by 250 mg/m2 weekly). Patients received a median of 8 infusions (range 1–11). Table 1:

Includes cases also reported as infusion reaction. Infusion reaction is defined as any event described at any time during the clinical study as “allergic reaction” or “anaphylactoid reaction”, or any event occurring on the first day of dosing described as “allergic reaction”, “anaphylactoid reaction”, “fever”, “chills”, “chills and fever”, or “dyspnea”. Based on laboratory measurements, not on reported adverse events, the number of subjects with tested samples varied from 205–206 for Erbitux plus Radiation arm; 209–210 for Radiation alone. Acneform rash is defined as any event described as “acne”, “rash”, “maculopapular rash”, “pustular rash”, “dry skin”, or “exfoliative dermatitis”.

The incidence and severity of mucositis, stomatitis, and xerostomia were similar in both arms of the study. Late Radiation Toxicity The overall incidence of late radiation toxicities (any grade) was higher in Erbitux in combination with radiation therapy compared with radiation therapy alone. The following sites were affected: salivary glands (65% versus 56%), larynx (52% versus 36%), subcutaneous tissue (49% versus 45%), mucous membrane (48% versus 39%), esophagus (44% versus 35%), skin (42% versus 33%). The incidence of Grade 3 or 4 late radiation toxicities was similar between the radiation therapy alone and the Erbitux plus radiation treatment groups.

Adverse reactions occurring more frequently in Erbitux-treated patients compared with controls. 2 Adverse events were graded using the NCI CTC, V 2.0. 3 Infusion reaction is defined as any event (chills, rigors, dyspnea, tachycardia, bronchospasm, chest tightness, swelling, urticaria, hypotension, flushing, rash, hypertension, nausea, angioedema, pain, pruritus, sweating, tremors, shaking, cough, visual disturbances, or other) recorded by the investigator as infusionrelated. BSC = best supportive care The most frequently reported adverse events in 354 patients treated with Erbitux plus irinotecan in clinical trials were acneform rash (88%), asthenia/malaise (73%), diarrhea (72%), and nausea (55%). The most common Grades 3–4 adverse events included diarrhea (22%), leukopenia (17%), asthenia/malaise (16%), and acneform rash (14%). Immunogenicity As with all therapeutic proteins, there is potential for immunogenicity. Immunogenic responses to cetuximab were assessed using either a double antigen radiometric assay or an ELISA assay. Due to limitations in assay performance and sampling timing, the incidence of antibody development in patients receiving Erbitux has not been adequately determined. Non-neutralizing anti-cetuximab antibodies were detected in 5% (49 of 1001) of evaluable patients without apparent effect on the safety or antitumor activity of Erbitux. The incidence of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to Erbitux with the incidence of antibodies to other products may be misleading. DRUG INTERACTIONS A drug interaction study was performed in which Erbitux was administered in combination with irinotecan. There was no evidence of any pharmacokinetic interactions between Erbitux and irinotecan.

England Journal report, patients started calling their physicians and saying ‘I am not going to take that medicine,’ but it wasn’t true and they were misled. We are now trying to make the point by using data to argue that the report was not well founded.”

USE IN SPECIFIC POPULATIONS Pregnancy Pregnancy Category C There are no adequate and well-controlled studies of Erbitux (cetuximab) in pregnant women. Based on animal models, EGFR has been implicated in the control of prenatal development and may be essential for normal organogenesis, proliferation, and differentiation in the developing embryo. Human IgG is known to cross the placental barrier; therefore, Erbitux may be transmitted from the mother to the developing fetus, and has the potential to cause fetal harm when administered to pregnant women. Erbitux should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Pregnant cynomolgus monkeys were treated weekly with 0.4 to 4 times the recommended human dose of cetuximab (based on body surface area) during the period of organogenesis (gestation day [GD] 20–48). Cetuximab was detected in the amniotic fluid and in the serum of embryos from treated dams at GD 49. No fetal malformations or other teratogenic effects occurred in offspring. However, significant increases in embryolethality and abortions occurred at doses of approximately 1.6 to 4 times the recommended human dose of cetuximab (based on total body surface area). Nursing Mothers It is not known whether Erbitux is secreted in human milk. IgG antibodies, such as Erbitux, can be excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Erbitux, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. If nursing is interrupted, based on the mean half-life of cetuximab [see Clinical Pharmacology (12.3) in Full Prescribing Information], nursing should not be resumed earlier than 60 days following the last dose of Erbitux. Pediatric Use The safety and effectiveness of Erbitux in pediatric patients have not been established. The pharmacokinetics of cetuximab have not been studied in pediatric populations. Geriatric Use Of the 1062 patients who received Erbitux with irinotecan or Erbitux monotherapy in five studies of advanced colorectal cancer, 363 patients were 65 years of age or older. No overall differences in safety or efficacy were observed between these patients and younger patients. Clinical studies of Erbitux conducted in patients with head and neck cancer did not include sufficient number of subjects aged 65 and over to determine whether they respond differently from younger subjects. Of the 208 patients with head and neck cancer who received Erbitux with radiation therapy, 45 patients were 65 years of age or older. OVERDOSAGE The maximum single dose of Erbitux administered is 1000 mg/m2 in one patient. No adverse events were reported for this patient. NONCLINICAL TOXICOLOGY Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term animal studies have not been performed to test cetuximab for carcinogenic potential, and no mutagenic or clastogenic potential of cetuximab was observed in the Salmonella-Escherichia coli (Ames) assay or in the in vivo rat micronucleus test. Menstrual cyclicity was impaired in female cynomolgus monkeys receiving weekly doses of 0.4 to 4 times the human dose of cetuximab (based on total body surface area). Cetuximab-treated animals exhibited increased incidences of irregular or absent cycles, as compared to control animals. These effects were initially noted beginning week 25 of cetuximab treatment and continued through the 6-week recovery period. In this same study, there were no effects of cetuximab treatment on measured male fertility parameters (ie, serum testosterone levels and analysis of sperm counts, viability, and motility) as compared to control male monkeys. It is not known if cetuximab can impair fertility in humans. Animal Pharmacology and/or Toxicology In cynomolgus monkeys, cetuximab, when administered at doses of approximately 0.4 to 4 times the weekly human exposure (based on total body surface area), resulted in dermatologic findings, including inflammation at the injection site and desquamation of the external integument. At the highest dose level, the epithelial mucosa of the nasal passage, esophagus, and tongue were similarly affected, and degenerative changes in the renal tubular epithelium occurred. Deaths due to sepsis were observed in 50% (5/10) of the animals at the highest dose level beginning after approximately 13 weeks of treatment. PATIENT COUNSELING INFORMATION Advise patients: • To report signs and symptoms of infusion reactions such as fever, chills, or breathing problems. • Of the potential risks of using Erbitux during pregnancy or nursing and of the need to use adequate contraception in both males and females during and for 6 months following the last dose of Erbitux therapy. • That nursing is not recommended during, and for 2 months following the last dose of Erbitux therapy. • To limit sun exposure (use sunscreen, wear hats) while receiving and for 2 months following the last dose of Erbitux.

He said healthcare providers should reassure their patients that there is no link between bisphosphonate use and esophageal cancer. According to the National Cancer Institute Surveillance, Ep- John Bilezikian, MD idemiology and End Results (SEER) database, the incidence of esophageal cancer in American men and women 65 years of age is 23.3 per 100,000 per year. In Caucasian women 65 years of age, the incidence is 11.2 per 100,000 per year. Bilezikian said the incidence of esophageal cancer events observed among risedronate or placebotreated patients was consistent with the background rates in the population. David Prelutsky, MD, associate clinical professor of medicine at Washington University School of Medicine, St. Louis, Missouri, said these finding are very important because they help clarify this area of controversy. “This study is clinically relevant, as it reassures primary care physicians, who prescribe the bulk of bisphosphonates, that they are doing no harm. No physician wants to prevent one problem and then possibly cause another with a treatment. These data are reassuring,” said Prelutsky in an interview with The Oncology Pharmacist. ● —John Schieszer

NCCN Updates Breast Cancer Guidelines New breast cancer guidelines from the National Comprehensive Cancer Network (NCCN) include three notable updates. First, despite the increasing number of women with cancer in one breast who choose to have the other breast removed, the updated guidelines discourage prophylactic mastectomy except for women who are at high risk. If prophylactic mastectomy is being considered, according to the NCCN guidelines, its benefits must be balanced with the risk of disease recurrence, the social and psychological issues associated with bilateral mastectomy, and the overall risks of contralateral mastectomy. Another change is that the guidelines now recommend sentinel node mapping and excision rather than full axillary lymph node dissection for women with clinically negative lymph nodes, provided that they are being treated by clinicians with experience in sentinel node biopsy. The guidelines also include a new regimen (fluorouracil/ epirubicin/cyclophosphamide followed by weekly paclitaxel) as an option for adjuvant therapy for invasive breast cancer.

To get started, choose a physician champion who is the most likely to be both sympathetic to standardization and (if possible) inspire buy-in from other physicians.

Planning for a Great Residency Project Continued from cover can provide many learning opportunities for the resident and preceptor. Using a structured plan for conducting a residency project will enhance the educational experiences as well as allow for project completion during the residency year.

Generating an idea for the project Generating the idea for the project will require a lot of input from the preceptor. Because work on the project should start as soon as possible in the year, many residency programs generate project concepts before the resident even begins the program. Some of the best residency projects arise out of practice-based problems, after looking backward to find the root of the problem. Project ideas can also be developed out of departmental strategic goals and quality improvement initiatives, as well as national benchmarks, such as Joint Commission requirements and the National Patient Safety Goals. The best projects are concise, interesting to both the resident and preceptor, and relevant to pharmacy practice. Projects with a focus that is too broad or that contains too many objectives can be very problematic. The scope of the project must remain contained to provide a quality learning opportunity and to make sure that the project can be completed during the residency year. Handing projects from one resident to the next does not allow the residents to participate during all phases of the project. “Project drift” can occur when the project’s goals shift because of new obstacles or when newcomers to the project propose a new focus to the project. This should be avoided. In projects based on implementation of a process change, thought should be given to designing the intervention at this stage. The intervention should be accomplishable given the resources available during the project year and afterward, so that the project will yield useful outcomes, and should rely as little as possible on the availability of outside resources (eg, information technology [IT] support, physician time). The purpose of the study and primary and secondary outcomes of the study should be set, and the resident should be able to state them in one or two simple sentences. Designing the study The next step in a successful residency project is the creation of a comprehensive timeline. Essentially, this outlines the steps involved in project completion and the estimated time needed. Time spent in this phase will pay off later in increased efficiency. It allows for identification of when resources (eg, resident project time, IT

support) will be needed. Responsibilities and roles of the project team members should also be assigned. Regular meetings should be scheduled to track progress as well as identify and solve roadblocks so that the project can continue successfully. Delays will be encountered in every residency project, and setting an aggressive timeline can allow for unexpected delays and ensure that the project is completed. an intervention, but is prone to tempoAfter setting a timeline, the next step ral bias.

The resident should think ahead at this point to how the data will be analyzed and presented. This will help him or her focus on the outcomes of interest. For example, if the proportion of patients with creatinine clearance <30 mL/min is needed, collect that data as a yes/no field, instead of recording all the laboratory values on admission. Sample size in a randomized controlled trial is defined by statistical calculations, but in quasi-experimental designs, the sample size is usually estimated based on the personal experience of the preceptor and available time and resources. The datacollection tool should be prepared at this point, including only the relevant information needed. The data-collection tool should be tested on a few patients before fine-tuning it. A plan for removing patient-specific data should be made, to protect the patients’ privacy. Data-collection tools can range from simple onepage paper forms to complicated database-driven electronic tools, based on the needs of the project.

Getting approval The next step in the process is writing the protocol and the institutional review board (IRB) submission. If all the aspects discussed have been considered, writing the proposal should be fairly simple. A usual proposal outline includes an introduction/justification, purpose/outcomes, methods, plan for analysis, data-handling plan, and references. Obtaining IRB approval ensures that the project is ethical and protects the human subjects and their privacy. It is required for projects that generate data that will be published or presented outside of the institution. Most IRBs classify projects according to the risk they pose to the patients. Many residency projects will qualify for the less intensive “exempt” or “expedited” reviews, because they pose minimal to no risk to the patient. Implementing the project After approval by the IRB and residency advisory council, the project can proceed. If the project is using a quasiexperimental design, data collection is usually the next step. It is important for Continued on page 30

Cardiac Toxicity and Breast Cancer: Prevention, Monitoring, and Treatment ORLANDO—Cardiac toxicity related to chemotherapy is not a new topic but it is an increasingly important one in light of emerging data showing adverse effects from many molecularly targeted agents as well as the older anthracyclines. Especially for patients with breast cancer, there is keen interest in better understanding the true level of risk and the best means of preventing, monitoring, and treating cardiac toxicity. Concerns have been raised about trastuzumab, especially when it is given in conjunction with an anthracycline, which is a common practice. But at the 2009 annual meeting of the American Society of Clinical Oncology (ASCO), an international group of investigators from the phase 3 Herceptin Adjuvant (HERA) trial reported that the incidence of cardiac end points remains low even with longer-term follow-up. Investigators assessed the cardiac

United Kingdom (a nonprofit research foundation). Cardiac dysfunction in the trastuzumab group after 1 year was 0.6% for severe CHF and 3.0% for confirmed significant LVEF drop. After 3.6 years, the incidence of cardiac dysfunction after trastuzumab remained low: 0.8% for severe CHF and 3.6% for confirmed significant LVEF drop. In the observation arm, there were no cases of severe CHF, but 0.6% had confirmed significant LVEF declines, and one patient suffered a cardiac death, the study found. Of the 73 patients in the trastuzumab group with a cardiac end point, 59 (80%) recovered after an average of 6 months. There was evidence of progressive cardiac disease in six of 1682 patients, but the remaining affected patients had a favorable outcome, Procter said. All occurrences of severe CHF and 85% of the confirmed significant LVEF

Several cardiac end points were evaluated: • Significant drop in left ventricular ejection fraction (LVEF), defined as an absolute decline of ≥10% to <50% • Confirmed significant LVEF drop, defined as an asymptomatic (New York Heart Association [NYHA] class I) or mildly symptomatic (NYHA class II) significant LVEF drop, unless the next LVEF assessment indicated a return to levels that did not meet the definition of significant LVEF drop, or as identified by the treatment-unblinded cardiac advisory board • Severe congestive heart failure (CHF, NYHA class III or IV and significant LVEF drop). “The cumulative incidence of any type of cardiac end point among patients randomized to 1 year of trastuzumab increased during the scheduled treatment period, but remained relatively constant thereafter,” reported Marion Procter, MSci, of Frontier Science Scotland, Ltd, Kincraig, Kingussie,

drops occurred during the scheduled treatment period. In contrast, anthracycline-associated cardiotoxicity can occur years after treatment, the authors pointed out. “Cardiac dysfunction in the trastuzumab group is consistent with preclinical findings that in trastuzumabassociated cardiac dysfunction, no significant rate of myocardial cell death is observed,” he said. “This is different from the mechanism of anthracyclineassociated cardiotoxicity.” These findings are consistent with those of a study reported at the Canadian Cardiovascular Congress 2009, which showed that trastuzumabrelated cardiac toxicity is “largely reversible.” In a study by Michael McDonald, MD, of the Heart Function Clinic at Toronto General Hospital and associates, 14 of 18 patients with breast cancer who were treated with trastuzumab had decreases in LVEF of ≥10% and showed signs of heart failure. Trastuzumab therapy was stopped in 13 of these patients, and at 3 months’ follow-up, all had nearnormalization of LVEF and improvement in symptoms. Patients were able to resume trastuzumab therapy and completed the course of treatment.

Heart disease and breast irradiation In another study presented at the ASCO annual meeting, Harvard investigators examined the cardiac effects of left-sided chest irradiation in breast cancer patients in the Nurses’ Health Study and found risk to be associated with baseline Framingham risk score. The study population included 3849 women with nonmetastatic breast cancer who were treated with radiotherapy. They were categorized according to low (n = 1764), intermediate (n = 1495), and high (n = 601) Framingham score, and risk of coronary heart disease (CHD) was determined after adjusting for age and CHD risk factors. The investigators found that left-sided breast radiotherapy raised the risk of having a CHD event by 80% in women with low baseline cardiac risk, but did not increase risk in the other two cohorts, reported Ronald C. Chen, MD, of the Harvard Radiation Oncology Program, Boston. “With modern radiotherapy techniques,” he suggested, “this difference may be smaller.” The findings could have implications for treatment decision-making. “A simple office-based Framingham score can be calculated to assess baseline cardiac risk. Women with earlystage left-sided breast cancer and low baseline cardiac risk should weigh the potential benefits of breast conservation against a small absolute increase in risk of CHD after radiotherapy,” he suggested. Patients often not referred for care Certainly, one means of managing chemotherapy-related toxicity is to diagnose and treat it early and appropriately; however, Stanford University investigators have shown that cancer patients who “silently” develop left ventricular dysfunction may not be referred to cardiologists. The study was presented at the American College of Cardiology (ACC) annual scientific session in April. In the retrospective analysis led by Geoffrey Yoon, MD, based on 88 patients receiving anthracyclines or trastuzumab between 2005 and 2007, mean LVEF (60% at baseline) dropped below normal during or after chemotherapy in 41% of patients, of which 25% had no overt symptoms of heart failure. Among the asymptomatic group, only 37% were referred to a cardiologist, 33% received an angiotensinconverting enzyme inhibitor or angio-

tensin-receptor blocker, and 41% received a beta blocker.

Optimal monitoring of chemotherapy patients Also at the ACC session, Daniel J. Lenihan, MD, professor of cardiology at The University of Texas M. D. Anderson Cancer Center, Houston, discussed how best to monitor for cardiac effects. Guidelines recommend measuring LVEF periodically, but this is insufficient because more than one third of patients with heart failure have normal ejection fractions, he pointed out. Furthermore, as the “mainstay” of diagnosis, symptomatology is insufficient as well, he added, and biomarker testing is not yet recommended, although troponin and brain natriuretic peptide levels have been found useful. Lenihan’s observations were echoed in a recent article in The Lancet Oncology (2009;10:391-399), which emphasized that LVEF is commonly used for screening for toxic effects but underestimates cardiac damage. Altena and colleagues further maintained that evidence to support current guidelines for monitoring is not robust. The authors reviewed the current data for the various approaches and concluded: • Echocardiography assesses systolic and diastolic cardiac function. Especially when it involves contemporary techniques, such as tissue velocity imaging of the early diastole, strain, and strain rate, echocardiography might permit earlier detection of subclinical signs of cardiac dysfunction. • Multigated acquisition (MUGA) scintigraphy is a reliable method for assessing LVEF but is somewhat insensitive for detecting subtle changes in cardiac function. MUGA scintigraphy, therefore, has limited value in the early detection of cardiotoxicity. • Serum cardiac biomarkers are promising as a screening strategy for early cardiovascular damage. • Cardiac magnetic resonance imaging, combined with gadolinium enhancement, is a promising screening strategy for the detection of subclinical damage. Persistent increases in troponin I or N-terminal pro-brain (B-type) natriuretic peptide concentrations seem to identify patients at risk for cardiotoxicity. ● —Caroline Helwick

Although a relatively unique scenario, this case illustrates the potential for severe complications from cancer and CIPN.

Pathophysiology and Epidemiology It has been hypothesized that neurotoxic chemicals directly damage nerve fibers by inactivation of components required to maintain the metabolic needs of the axon. The longer and larger distal axons are affected first and this may result in interruptions of axonal transport and degeneration of myelinated nerve fibers and unmyelinated axons.8-10 In a recent animal-model study of paclitaxel-induced CIPN, abnormalities in the axonal mitochondria of sensory nerves were found to contribute to paclitaxel-induced neuropathic pain.12 Under normal circumstances, large sensory neurons do not conduct noxious stimuli. These large myelinated sensory fibers are preferentially injured by neurotoxic chemotherapeutic agents. Injury or damage to large sensory fibers by chemotherapeutic treatments can also result in the paresthesias, dysesthesias, and decreased proprioceptive abilities. These stimuli can be detected by nerves within the body as well as by the semicircular canals of the inner ear. Thus, CIPNs induce a type of neuropathic pain and represent a serious yet understudied consequence of cancer treatment. The sensory and motor symptoms and signs of CIPNs are potentially disabling and can have a significant impact on QOL for patients with cancer.13,14 Moreover, even when CIPN is not a dose-limiting side effect, its onset may severely affect QOL and cause chronic discomfort and pain.6-11 Prevalence and incidence The prevalence of CIPNs is not known because of a lack of adequate standardized assessment, measurement, and reporting mechanisms.3,9,11 Toxicity-grading scales used to detect CIPN vary widely, and specific guidelines for these instruments are lacking. The incidence of CIPN varies depending on the drugs, dosage, and treatment schedules used.3-11 The incidence of severe CIPN has been estimated at about 3% to 7% in individuals treated with single agents and upward of 38% in those treated with multiple chemotherapeutic agents.3-11 Risk factors Risk factors associated with worsening CIPN symptoms include prior use of chemotherapies (particularly platinum-based therapies), older age, and female gender. Comorbid conditions that appear to place patients at greater risk for CIPN include diabetes, human immunodeficiency virus infection, alcoholism, preexisting neuropathies (diabetic neuropathy, small fiber neuropathies), and vitamin B deficiencies.3,6,11,13-15 The symptoms associated with CIPNs also vary widely (Table 1), and little is known about other risk factors. Moreover, even when neurophysiologic methods are used to diagnose CIPNs, there is still wide variation in the resultant symptoms, which enhances the difficulty in predicting and modeling which patients are potentially at the greatest risk.4-11

November/December 2009

Mechanisms The sensory and motor symptoms and signs of CIPNs are potentially disabling and can have a significant impact on QOL.1-11 Yet, the mechanisms and risk factors associated with the development of CIPNs have not been fully elucidated. Several interesting mechanisms have been proposed. For instance, in patients with cancer, the immune response to tumor cells contributes to an already adverse proinflammatory state. One potential consequence is that tumoral invasion at central or peripheral sites can lead to mechanical damage, proteolysis, and the release of inflammatory pain mediators, including proinflammatory cytokines (ie, interleukin-1, interleukin-6, and tumor necrosis factor-a). These may result in damage to surrounding tissues and may also play a prominent role in the initiation, development, and maintenance of chronic pain states, including neuropathic pain.16-26 Other research has examined the impact of platinum-based cancer chemotherapies on mitochondrial function.27 Alterations in mitochondrial function has been noted in cancer cell resistance to chemotherapeutic agents. Cisplatin’s toxic side effects appear to be associated with mitochondrial injury in vivo and in vitro, highlighting the plausible role of mitochondria, including the role of production of mitochondrial electron transport chain reactive oxygen species in models of other forms of painful peripheral neuropathy.27-30 Variation in symptoms: presentation, progression, and resolution The primary effects of CIPN are sensory, occurring in a stocking-and-glove distribution in the toes and fingers. The lack of gold-standard measures for CIPN and the wide variation in symptoms contribute to limitations in symptom management in patients. CIPN can vary in its onset, severity, and length, and its resolution cannot be predicted, as the symptomology can last from a few days to a lifetime.3-11 The symptoms are described briefly below. • The majority of patients report a gradual onset of neuropathic symptoms, although some develop symptoms more rapidly.3-11 • The primary effects are sensory, occurring in a stocking-and-glove distribution in the toes and fingers.3-11 • Terms such as “burning,” “tingling,” “electric shock sensation,” and “painful numbness” have all been used to describe the sensations.4,8 • Patients may also report increased pain during walking, with descriptions of sensations such as “walking on shards of glass” or “stepping on razorblades.”4,8 • Physical examination may reveal tactile allodynia, cold allodynia, hypersensitivity, and loss of deep tendon reflexes.4,8 • Motor symptoms such as declines in muscle strength can lead to muscle weakness and atrophy, precipitating functional impairment. • Patients may also experience a loss of proprioception, the unconscious perception of movement and spatial orientation within the body. In addition, loss of proprioception can lead to significant safety issues.8,9,13 Patients without proprioception are

at a great risk for falls because they also tend to lose all sense of the position of their feet. This raises concerns about their ability to drive safely, particularly when they are unable to feel the brakes or lack the strength to press a pedal adequately.7,9,15 Heterogeneity in CIPN-related symptoms can range from an almost exclusively sensory to a sensory-motor neuropathy, with or without clinical evidence of autonomic impairment.3,11,13-15,24-26 Recent insight from animal and human studies suggests that the great heterogeneity in the underlying mechanism(s) of nerve injury caused by individual agents may partly explain the wide variation in the resultant symptoms.3,11,24,26,31-34 Chemotherapeutic toxicity is also influenced by multiple genetic factors and nongenetic factors, including age, gender, and drug-drug interactions.26,31-38 The manifestations of adverse drug reactions also differ between men and women. Women tend to experience greater toxicity from chemotherapeutic drugs than men.34 Recent studies suggest that the mechanisms underlying the various forms of peripheral neuropathy may actually be different, and therapies have to be tailored in light of these different neurotoxic effects.27 These issues further contribute to the difficulties in Continued on page 18

rier that further contributes to the inadequate pain assessment and management of CIPNs.

Prevention of CIPN Chemoprotectants Chemoprotectants such as amifostine have been tested as a means of detoxifying chemotherapy and facilitating DNA repair while not interfering with the efficacy of chemotherapy (Table 2). In the studies testing the effect of amifostine on peripheral neuropathy associated with taxane-based chemotherapy regimens, no differences were found in sensory or motor neurotoxic symptoms in patients treated with amifostine. Amifostine was also found to be ineffective in preventing or reducing the neurotoxic effects of highdose paclitaxel.42-44

Vitamin E Vitamin E has been thought to protect against cellular oxidative damage and side effects, such as numbness, tingling, burning, and/or pain in peripheral extremities produced by cisplatin and other cytotoxic drugs. Three studies examined the cytoprotective effect of vitamin E supplementation on the development of CIPN following the administration of cisplatin, paclitaxel, or a combination regimen.45-47 The findings, based on subjective, clinical, and electrophysiologic assessments, showed that the incidence of neurotoxicity was lower in the group that received vitamin E as compared with the control group. Further randomized clinical trials are needed, however, to evaluate the role of vitamin E in the prevention and treatment of CIPN. Continued on page 20

hemotherapy-induced peripheral neuropathy (CIPN) is a relatively common and poorly treated adverse effect of several anticancer drug classes, including the taxanes, vinca alkaloids, platinum analogs, and the antimyeloma drugs, thalidomide, lenalidomide, and bortezomib. Because there are no proven therapies to treat CIPN, methods to prevent CIPN are particularly important. The ability of any given agent to prevent CIPN needs to be weighed against any real or theoretical concern of diminished antitumor effect. Because the mechanisms of CIPN are thought to be at least in part an extension of the drug’s mechanism of antitumor effect (eg, tubulin inhibition, DNA adduct formation), the proposed protective agents (amifostine, calcium/magnesium, vitamin E, glutamine, N-acetylcysteine, glutathione, acetyl L-carnitine, and erythropoietin) need to be used thoughtfully. This is particularly true given that there is no strong evidence that many of these agents lower rates of CIPN. One method of reducing the rates of CIPN is related to advances in drug development and formulation of anticancer drugs. For example, carboplatin was developed by the addition of a more complex and bulky-leaving group to the cisplatin molecule, leading to the production of less reactive platinum species and lower rates of several of the toxicities associated with cisplatin, including CIPN. Oxaliplatin is much more like cisplatin despite its more complex chemical structure, and substantial reduction in CIPN compared with cisplatin has not been realized. Cisplatin may be

more likely to produce permanent neurologic damage, consistent with the science showing three times more platinum-DNA adduct formation in the dorsal root ganglia with cisplatin compared with oxaliplatin.1 The CIPN associated with docetaxel is less severe than that with paclitaxel. Variation is also seen among the vinca alkaloids, vinblastine and vinorelbine, which are associated with lower rates of CIPN compared with vincristine. The differences between these antimitotic drugs are based on differences in their affinity for axonal microtubules. In addition to drug selection that can minimize CIPN, a number of new formulations of neurotoxic chemotherapy may improve tolerability. For instance, although nanoparticle albumin-bound paclitaxel is not less likely to produce CIPN than solvent-based paclitaxel, the CIPN that develops may be more reversible.2 The inhibitors of tumor progression commonly used to treat multiple myeloma (thalidomide, lenalidomide, and bortezomib) have differing liability for CIPN. Thalidomide is a common cause of CIPN, which is only slowly or incompletely reversible and related to cumulative dose. In comparison, CIPN is uncommon with lenalidomide and, when present, is usually mild. Bortezomib is associated with neuropathy in approximately one third of patients.3 Bortezomib-induced CIPN, however, is generally more rapidly reversible than that with thalidomide, and resolves in most patients after dose reduction or discontinuation.3,4 Unfortunately, determining the clinical nature of the

CIPN associated with these agents is difficult given that patients with multiple myeloma may have a history of receiving neurotoxic therapy, and the underlying disease itself may be associated with neurologic deficit.4 It is not always possible to switch between drugs of the same class because of either nonequivalence in a given tumor or lack of data demonstrating clinical equipose. In addition, lower rates of CIPN are often at the cost of higher rates of myelosuppression or other toxicities that may create equal or greater clinical issues. In conclusion, although prevention of CIPN is preferred given the lack of agents to effectively treat CIPN and the potential irreversibility of the damage, there are limited data on the value of preventive agents. In addition, antagonism of antitumor activity with preventive therapies is not a settled issue. The appropriate selection of both analog and formulation may be an effective method of minimizing this important complication of chemotherapy. ●

Calcium and magnesium Infusions of calcium and magnesium have been used as a means of preventing oxaliplatin-associated CIPN. Oxalate, an oxaliplatin metabolite, seeks out and binds to calcium and magnesium.48 In one study, 140 patients were randomly assigned to receive calcium gluconate and magnesium sulfate or placebo before and after oxaliplatin to reduce neurotoxicity. Improvements in the clinical manifestations of acute neurotoxicity were

reported after infusion of calcium and magnesium, and at the end of oxaliplatin therapy, 65% of the patients in the calcium/magnesium infusion group had no symptoms of neuropathy compared with only 37% in the control group.48 There was concern that tumor response rates may be lower in patients who received calcium and magnesium infusions. A subsequent review of computed tomography scans from the trial, however, showed that the antitumor response rates were actually

numerically higher in the group that received the calcium and magnesium infusions compared with those who received placebo. Thus, calcium and magnesium infusions appear to offer a safe, cost-effective means of preventing oxaliplatin-related peripheral neuropathy.49,50

nowledge of current treatment and supportive care strategies for common cancer-related toxicities is critical to the provision of quality nursing care. Visovsky and Moore provide a comprehensive overview of the epidemiology, prevalence, characteristics, and management of chemotherapyinduced peripheral neuropathy (CIPN). The article will not only serve as an excellent resource for clinical oncology nurses, but also allow them to provide comprehensive education for cancer patients about what to expect with CIPN. The assessment and management of CIPN continues to be a clinical challenge for healthcare professionals for several reasons that are addressed by the authors and others. First, there is great variability in the characteristics of symptoms related to CIPN. This may, in part, be related to the specific class of chemotherapeutic agents that causes CIPN, but currently there is no conclusive evidence that explains this variability. The variability in symptom characteristics also poses a clinical challenge for developing effective assessment and follow-up protocols for CIPN. Second, although research is ongoing, CIPN is still overall a poorly understood phenomenon. Current evidence related to the underlying neurobiology, actual prevalence rates, and a lack of definitive animal models are factors that affect our overall understanding of CIPN.1 Finally, despite the growing number of clinical trials testing various therapeutic options for CIPN, currently there is no standard, evidence-based treatment for the prevention or treatment of CIPN.2 Understanding the relationship between CIPN and quality of life (QOL) is important not only for patients but also for nurses caring for individuals with cancer. To thoroughly understand how CIPN affects the QOL of our patients, there is a need to capture the overall experience of living with CIPN from the patient’s perspective. Few qualitative studies conducted in recent years have attempted to understand

20

CIPN from the subjective perspective. Bakitas conducted an excellent qualitative study that described the CIPN symptom experience and the effect of symptoms on everyday life.3 Patients described CIPN as “background noise” that can be overshadowed by other treatment- and disease-related issues, but CIPN’s unpleasantness can interfere with daily activities and socialization. The awareness of CIPN was often inaccurate and its occurrence surprising because most patients did not recall being educated or advised to anticipate the symptoms. When monitoring CIPN, clinicians primarily focused on how the symptoms affected motor functionality (dexterity, gait) but rarely asked about CIPN’s effect on daily living. CIPN caused disruptions with daily living, leisure, work, and family roles. Patients who reported a pain component to their CIPN often experienced functional difficulties, fatigue, sleep disturbance, and mood disturbances. Patients also described the use of multiple processes in learning to live with CIPN. Similar results have been described in another qualitative study conducted by Closs and colleagues4 as well as in our work at the City of Hope. Our descriptive, mixed methods study explored the impact of peripheral neuropathy on QOL in 53 patients with colorectal cancer. Our qualitative data suggest that although patients did not find the dysesthesias and cold-related allodynia distressing, the acute sensations were surprising when first experienced, and patients made adjustments in life (eating and drinking habits related to cold foods and beverages) to cope with these neuropathic symptoms.5 There are several ways that nurses can contribute clinically and scientifically to the sparse evidence in CIPN prevention and management. By keeping abreast with the most current information on CIPN management, nurses are better equipped to provide quality care and support to cancer patients living with CIPN. The prompt assessment of symptoms related to CIPN is essential for determining appro-

priate and effective management strategies. The assessment of CIPN should continue throughout treatment and beyond, because chronic CIPN can occur months and even years beyond treatment.6 Most important, nurses must be vigilant in educating patients on what to expect with CIPN. It is evident from some of the current evidence that clinicians are not doing an optimal job of providing patients with timely information on CIPN. Beyond pharmacologic treatments, it may also be helpful for nurses to discuss nonpharmacologic supportive care strategies to cope with CIPN, such as personal safety measures to prevent burns, falls, or other problems that may be related to sensory motor deficits.7 Finally, for nurses who are committed to advancing the science of CIPN management, there is a need for more studies and evidence that focuses on outcomes beyond the efficacy of therapeutic agents.8 Studies that characterize the time of onset, duration, and resolution or persistence of CIPN are needed to develop a more comprehensive and subjective understanding of CIPN.1 ●

Carbamazepine was tested in the prevention of CIPN in a single nonrandomized pilot study consisting of 10 previously treated patients with advanced colorectal cancer receiving oxaliplatin, leucovorin, and 5-fluorouracil. Results indicated the absence of World Health Organization grade 2 to 4 neuropathy development in the patients treated with carbamazepine compared with 30% who experienced grade 2 to 4 neuropathy in a historical control group.51 In a randomized controlled trial, von Delius and colleagues tested the efficacy and safety of carbamazepine for the prevention of oxaliplatin-associated neuropathy in 36 patients with advanced colorectal cancer.52 No differences were found between the groups on assessments of neurotoxicity. Further randomized, placebo-controlled trials are necessary to determine if carbamazepine can be used to prevent or treat CIPN.

Glutamine Glutamine, a neutral gluconeogenic nonessential amino acid, is thought to have neuroprotective effects for patients receiving paclitaxel.53 In one study, 12 women with advanced breast cancer were given glutamine 10 g daily for 4 days starting 24 hours after completion of paclitaxel and 33 women did not receive glutamine. Only 8% of women treated reported dysesthesias in the fingers and toes compared with 40% of the women who did not receive glutamine.54 In another study, Stubblefield and colleagues examined the neuroprotective effect of glutamine on 46 patients scheduled to receive high-dose paclitaxel before stem cell transplant.53 Seventeen patients received glutamine, and 29 patients made up the control group. Responses to questions about neurologic symptoms and results of electrodiagnostic testing indicate that those who received glutamine developed less weakness, loss of vibratory sensation, and toe numbness compared with those in the control group. In a nonrandomized pilot study, Wang and colleagues tested the efficacy of glutamine for reducing the incidence and severity of peripheral neuropathy in patients receiving oxaliplatin in 86 patients with colorectal cancer.55 Glutamine supplementation significantly reduced the incidence and severity of oxaliplatin-induced neuropathy. The percentage of grade 3 to 4 sensory neuropathy was lower in the glutamine group after four cycles of treatment and remained that way for six cycles. The results suggest that glutamine is a potential neuroprotective agent but must be studied in larger populations in a randomized, placebo-controlled trial. Concerns still exist about glutamine supplements protecting tumor cells from the cytotoxic effects of chemotherapy.55 Glutathione Some evidence shows that glutathione, a naturally occurring thiol tripeptide, may also prevent neurotoxicity induced by platinum compounds by preventing the initial accumulation of platinum adducts in the dorsal root ganglia.56 Three studies testing the potential neuroprotective effects of glutathione have been published.5759 Following all cycles of chemotherapy, the incidence of neuropathy was greater in the placebo-treated arms compared with those who received glutathione. Further randomized clinical trials are needed to test the effectiveness of this agent in CIPN.

Treatment of CIPN Historically, treatments for CIPNs have been supportive.60 Neuropathic pain management is aimed at the reduction of symptoms, generally by suppressing neuronal activity, not glial cell activation, which has also recently been associated with the development and maintenance of chronic pain states.13,61 At this time, no medications exist that can fully relieve the sensory and motor loss associated with advanced CIPNs. The needs of patients with CIPNs are largely unmet because of the absence of adequate assessment and evidence-based treatments that could be widely applied across clinical CIPN patient populations and could potentially prevent or mitigate this increasingly common clinical problem.11 Gabapentin Gabapentin is an antiepileptic medication that has demonstrated efficacy for the treatment of neuropathic pain, possibly in patients with CIPNs. Gabapentin was initially synthesized to mimic the chemical structure of the neurotransmitter gamma-aminobutyric acid, but it is not believed to act on the same brain receptors. Although the exact mechanism of action is unknown, the therapeutic action of gabapentin on neuropathic pain is thought to involve voltage-gated calcium channels. In a phase 3, randomized, double-blind, placebocontrolled, crossover trial, 115 patients with symptomatic CIPN were randomized to receive either gabapentin or placebo over the course of two 6-week phases separated by a 2-week “washout” period. No significant differences were reported between the groups on scores of symptom distress or mood states. The only significant difference between the groups was in the McGill Pain Rating Index, which showed lower pain in the gabapentin group at the end of the first 6-week treatment period. The study failed to demonstrate the benefit of gabapentin to treat CIPN symptoms.62 Nortriptyline Nortriptyline, a tricyclic antidepressant, works by blocking the reuptake of serotonin and norepinephrine in the pain-modulating system within the CNS.63 In a randomized, double-blind, placebo-controlled, crossover study, 51 patients treated with cisplatin received escalating doses of nortriptyline up to 100 mg/day over a 4-week period. Responses to questionnaires concerning pain, sleep, QOL, and neuropathic symptoms also indicate a relatively modest benefit in cisplatin-induced paresthesia over the placebo group. Objective measures of neuropathy were not used in this small pilot study, and thus the effectiveness of nortriptyline in reducing paresthesias related to CIPN cannot be established. Acetyl L-carnitine Acetyl L-carnitine is an acetylated form of L-carnitine that has shown neuroprotective effects and may be useful in treating peripheral nerve injury. Two small studies examined the use of acetyl L-carnitine in the treatment of preexisting paclitaxel- or cisplatin-induced peripheral neuropathy.64 Patients who received acetyl L-carnitine showed improvement in neuropathy symptoms and in objective measures of sensory and motor neuropathy; however, small sample sizes and nonrandomized onegroup designs limit these studies. Further randomized

clinical trials are necessary before acetyl L-carnitine can be recommended as a potential treatment for CIPN.

Alternative treatments Acupuncture In one case series study testing the use of acupuncture in five patients with CIPN, this modality was found to improve sensation and gait, resulting in decreased analgesic use. Control of symptoms persisted for 6 months for four of the five patients treated.65 Physical activity/exercise Three relatively small studies examined progressive resistance exercise, aerobic exercise, and stretching exercises in the treatment of diabetic peripheral neuropathy and myotonic dystrophy. All three studies found significant improvement in stance, functional reach, and peroneal and sural motor nerve conduction velocity. The findings of these studies should be interpreted with caution, as they have not been replicated in patients who have or are at risk for CIPN.66-68 Pulsed infrared light therapy (PILT) PILT, also called anodyne therapy, consists of delivering infrared light to the feet of patients with diabetes, but it has not been tested as a treatment for CIPN. Following a series of treatments, significant improvement in sensation, neuropathic symptoms, and pain was evident in most patients.69 Prendergast and colleagues found anodyne therapy improved sensory impairments as measured by peroneal nerve function and current perception thresholds in 26 participants after 10 treatments delivered over 2 weeks, each lasting 40 minutes.70 In another study, significant improvements in sensation were found when PILT treatments were given for 30 minutes three times a week over an 8-week period.71 Transcutaneous electrical nerve stimulation (TENS) TENS has been tested in patients with diabetic neuropathy, but not in patient populations with cancer. In a randomized clinical trial of 19 patients with diabetic neuropathy, Forst and colleagues compared TENS with pseudostimulation by an electrically inactive device.72 Significant subjective improvements in neuropathy symptoms, including numbness, pain, and allodynia, were demonstrated in 70% of treatment group participants compared with 29% in the control group. Capsaicin ointment Capsaicin has been studied for the treatment of peripheral neuropathy in the diabetic population, with inconclusive results that prevent recommendation at this time. Although 10 patients who received capsaicin completed a study with a significant decrease in hypoesthesia, two patients discontinued treatment due to erythema or generalized allergic skin reaction at the application site.73 Conclusions Evidence supports the need for careful and ongoing assessment of CIPNs in patients receiving chemotherapy. Specifically, clinical practice procedures need to be developed that address the need for standardized assessContinued on page 22

ments of CIPN, the frequency of CIPN evaluations while undergoing chemotherapy, and the length of assessments once treatment is completed. In addition, there is a need to determine the clinically significant amount of sensory and motor changes noted in either sensory or motor nerves that may warrant a dose reduction in the treatment drug and/or the need for a rehabilitation evaluation by a physical or occupational therapist. In the absence of evidence-based prevention or treatment modalities for CIPNs, clinicians must educate their patients about the functional changes they may expect to occur as a result of neurotoxic chemotherapy and assist patients in developing strategies to manage limitations resulting from CIPNs. ●

Recent FDA Approvals Folotyn for Relapsed or Refractory Peripheral T-cell Lymphoma The first single-agent therapy for relapsed or refractory peripheral T-cell lymphoma, pralatrexate injection (Folotyn, Allos Therapeutics), has been approved by the US Food and Drug Administration (FDA). The approval for this indication was based on overall response rate. At current, improvement in progression-free survival and overall survival has not been demonstrated. Additional clinical studies are ongoing to verify and describe the agent’s clinical benefits.

Cervarix Cervical Cancer Vaccine The FDA has approved a new human papillomavirus (HPV) bivalent (types 16 and 18) vaccine, recombinant (Cervarix, GlaxoSmithKline) for the prevention of cervical precancers and cervical cancer associated with oncogenic HPV types 16 and 18 for use in girls and young

26

women aged 10 to 15 years. The approval was based on a study that showed the vaccine to be 93% efficacious in the prevention of cervical precancers associated with HPV 16 and 18 in women without evidence of current infection or prior exposure to these types of HPV at time of vaccination.

Votrient for Advanced Renal Cell Carcinoma The FDA has approved the oral agent pazopanib (Votrient, GlaxoSmithKline) for treatment of advanced renal cell carcinoma. The agent, which interferes with angiogenesis, was approved based on a 435-patient study that examined progression-free survival (PFS). PFS averaged 9.2 months for patients who received the drug compared with 4.2 months for those who did not.

Elitek for Management of Plasma Uric Acid Levels The FDA has approved rasburicase

G REEN H ILL H EALTHCARE C OMMUNICATIONS

(Elitek, sanofi-aventis US) for use in the initial management of plasma uric acid (PUA) levels in adults with leukemia, lymphoma, and solid tumor malignancies who are receiving anticancer therapy expected to result in tumor lysis syndrome and subsequent elevations of PUA. Approval was based on a phase 3 trial that demonstrated that rasburicase significantly reduced PUA levels compared with oral allopurinol (the current standard therapy).

Arzerra for Chronic Lymphocytic Leukemia The FDA has granted accelerated approval of ofatumumab (Arzerra, GlaxoSmithKline/Genmab) for use in patients with chronic lymphocytic leukemia (CLL) that is refractory to fludarabine and alemtuzumab. Approval was based on a study in which 42% of patients with treatment-refractory CLL responded to treatment with ofatumumab, a monoclonal antibody drug

targeting the CD20 protein on B cells. These patients had a median duration of response of 6.5 months. Common adverse events included neutropenia, pneumonia, pyrexia, cough, diarrhea, anemia, fatigue, dyspnea, rash, nausea, bronchitis, and upper respiratory tract infections.

Istodax for Cutaneous T-cell Lymphoma The FDA has approved romidepsin (Istodax, Gloucester Pharmaceuticals) for the treatment of cutaneous T-cell lymphoma in patients who have received at least one prior systemic therapy. Approval of the histone deacetylase inhibitor was based on efficacy data from two studies totaling 167 patients. The overall response rates, defined as the proportion of patients with confirmed complete response or partial response, were 34% and 35%. The complete response rate was 6% in both studies. ● November/December 2009

A Phase 2 Study for Patients With Relapsed/Refractory Mantle Cell Non-Hodgkin’s Lymphoma Primary Investigator André Goy, MD Primary Objective To determine the tumor response and duration of response of lenalidomide monotherapy in subjects with mantle cell lymphoma (MCL) who have relapsed or progressed after treatment with bortezomib or are refractory to bortezomib Key Eligibility Criteria* • Individuals with MCL previously treated with all of the following (alone or in combination): – Bortezomib† – An anthracycline or mitoxantrone – Rituximab – Cyclophosphamide • Individuals must have documented relapse after bortezomib treatment or be refractory to bortezomib • Excluding individuals who are candidates for high-dose chemotherapy/allogeneic stem cell transplant *Additional criteria apply. †Note: When the agent bortezomib is mentioned this also includes ANY BORTEZOMIB-CONTAINING REGIMEN.

Study Design

Pretreatment Phase (4 Weeks)

N=133

• MCL diagnosis confirmed by local pathological review

Treatment Phasea (until disease progression)

• Lenalidomide starting dose 25 mg po once dailyb

Lenalidomide will be dosed po once daily on days 1-21 of each 28-day cycle. Subjects with creatinine clearance ≥30 mL/min but <60 mL/min will receive a lower starting dose of lenalidomide 10 mg po once daily. Dose may be escalated to 15 mg po once daily if no dose-limiting toxicities occur during the first 2 cycles.

UPCI ranked 11th in funding from the NCI in 2007, and 12th among U.S. News & World Report’s “Best of the Best” cancer programs in the nation. UPMC’s network of 2300 physicians, scientists, staff, and other healthcare professionals provides clinical care to 30,000 patients annually at its facilities while engaging in cutting-edge cancer research. Medical, radiation, and surgical oncologists and disease-specific specialists collaborate closely in a model of multidisciplinary care. Ancillary service providers in behavioral medicine, rehabilitation, social work, palliative care, nutrition, and genetic counseling are incorporated into the multidisciplinary

team to ensure that all aspects of care are addressed. The hub and satellite network of UPMC Cancer Centers consists of more than 45 community-based locations in western Pennsylvania and two centers in Ireland. The hub-and-spoke model ensures extensive distribution of radiation therapy and medical oncology facilities throughout the tri-state region, said Barry Lembersky, MD, a medical oncologist. “Our pathways of standard of care are uniform throughout this area, and the full array of clinical trials is available to patients at all satellite facilities,” he said.

Thirteen areas of expertise The range of knowledge covers virtually all types of adult cancer, with 13 areas of expertise being recognized, including a world-renowned melanoma program. Other programs are devoted to brain cancers, breast cancer, colon and gastrointestinal cancers, head and neck cancers, leukemias and lymphomas, liver cancer, lung cancer, gynecologic cancers, prostate and urologic cancers, and stemcell transplantation. The Melanoma and Skin Cancer Program consists of both basic and clinical research and has patients coming from all over the world to participate in clinical trials for melanoma under the direction of John Kirkwood, MD. Major areas of research range from the development of a melanoma vaccine to the search for biomarkers to aid in the devel-

opment of personalized treatments. UPMC was one of the first centers to use a digital mole mapping system to assess high-risk patients for skin cancer. In addition, UPMC has “a well-organized pancreatic cancer program whereby patients with all forms of pancreatic cancer and all stages are seen in a multidisciplinary clinic with innovative clinical trials in the preoperative setting and the adjuvant and metastatic setting,” Lembersky said. For instance, a preoperative clinical trial of gemcitabine with radiation therapy and bevacizumab is in progress, with the goal of evaluating the downstaging and histologic changes that occur with such treatment. “That’s a pretty novel approach that holds promise not only for better outcome but for the paradigm of evaluating new drugs and new drug combinations; give the drugs prior to pancreatic resection to look for surrogate markers of response (ie, tumor necrosis), and correlate it with long-term outcome,” he said. “The treatment has been very well tolerated and resection rates are high. In most patients, there is evidence of significant necrosis and chemotherapy or radiation effect, and what that means for survivorship is uncertain at this time.” Other research involves the testing of a vaccine for colon cancer prevention in persons at high risk for developing the disease. In a novel approach, the vaccine is directed against an abnormal variant of the gene MUC1, which is altered and produced in excess in advanced adeno-

This set-up affords him an opportunity to stay current in each service. “You see everything, so you don’t lose touch,” he said. “It’s advantageous professionally and personally because it lessens the chance of burning out while always presenting a new challenge.

mas and cancer. Stimulating an immune response against the protein encoded by MUC1 in precancerous growths may not only trigger the immune system to destroy the abnormal cells to prevent progression to cancer but may also prevent polyp recurrence. MUC1 vaccines have been tested for safety and immunogenicity in patients with late-stage colon cancer and pancreatic cancer.

Integrated drug discovery program allows for range of studies A vertically integrated drug development program at UPCI, called Molecular Therapeutics Drug Discovery, employs 69 members with interests in one of four areas: chemical diversity, molecular targets, pharmacokinetics/ pharmacodynamics, and phase 1 clinical trials. “The goal is to have seamless movement from chemistry into patients, and if we make observations in patients, to be able to take them back and look at them on a mechanistic/molecular level,” said Merrill Egorin, MD, professor of medicine at UPCI. “We are one of the six NCI animal pharmacology contractors, so that puts us in the pipeline of any drug that the NCI is considering putting into patients,” he said. “We’ve got an early signal on what’s coming through the NCI. If we have inplace methods to measure the drug— we’ve defined its metabolism, we know its molecular targets, and we have assays to measure those molecular targets in animal models of tumors—it’s a huge strength when we put in a request to do a first-in-human study or phase 2 study,” Egorin said. Researchers at UPCI are also involved in a number of ongoing studies with the target poly (ADP-ribose) polymerase (PARP), an enzyme involved in the recognition of DNA damage and repair. By inhibiting PARP, the hope is that the activity of anticancer drugs can be potentiated, presumably by decreasing the resistance or increasing the sensitivity of tumor cells to standard chemotherapy. BRCA1- and BRCA2-mutated tumors should be specifically sensitive to inhibition of PARP, according to Egorin. This synthetic lethal approach has already been validated in vitro and in preclinical models. “There has already been a clinical study with a different PARP inhibitor that has demonstrated the case that BRCA tumors will respond to this, and the toxicities are essentially none,” he said. ● —Wayne Kuznar November/December 2009

PHARMACY CAREERS AND EDUCATION

Planning for a Great Residency Project Continued from page 13 the preceptor to monitor the resident closely during this phase. Many residency programs allow for special project time to be assigned, outside of rotational responsibilities. This is one of the phases where the timeline can go haywire, so planning for delays and close preceptor monitoring is necessary for a successful project. Gearing up for the collection of data in the post-phase may require some motivational skills on the part of the preceptor. 

Implementation of the intervention can be very rewarding for the resident. It may include committee decision making, presentations to administrators, designing therapy protocols, conducting process analysis, assisting in developing IT solutions, teaching pharmacists, physicians and patients, or re-engineering a problematic process. As much of this step as possible should be delegated to the resident. These career skills can contribute to the residentâ&#x20AC;&#x2122;s future plans.

Presentation of the project After analysis of the data and formulation of conclusions, the next step in a successful residency project is the preparation of the material for verbal and written presentation. Condensing the study method, data, and conclusions into a 10- to 20-minute presentation can be challenging. Many aspects can be summarized, given the likely audience of the presentation. Most data are best presented in graphic form. Comp-

licated tables and replication of the data-collection form or treatment protocol onto a single slide should be avoided. Adequate time should be devoted to a discussion of the conclusions, implications of the data, and the plan for future work. After initial slide review by the preceptor, the resident should be given opportunities to practice the presentation in front of an audience at least twice before the regional residency conference. In addition, the resident should take every opportunity to present the project internally to appropriate committees, departments, or task forces. Even if there is not time or opportunity for publication, the resident should write a manuscript based on the study, using a format appropriate for publication, to gain the experience of formal, scientific writing. A successful residency project can provide many important real-world learning experiences for the resident and foster the mentoring relationship between the resident and the preceptor. Advance planning can turn the residency project into a meaningful experience for both the resident and preceptor. â&#x2014;?

Concise Reviews of Studies Relevant to Cancer Care ■ Improved Event-free Survival in Children and Adolescents with Ph+ ALL Background: Imatinib monotherapy has been shown to produce high response rates in Philadelphia chromosome–positive (Ph+) acute lymphoblastic leukemia (ALL), but with recurrence in months. It has been used in combination with intensive hyperfractionated

cyclophosphamide, vincristine, doxorubicin, and dexamethasone therapy followed by blood and marrow transplantation (BMT) in adults with Ph+ ALL. Efficacy and tolerability with multiagent chemotherapy in children is not known. Design: Patients with Ph+ ALL aged 1 to 21 years (N = 92) received imatinib 340 mg/m2/day introduced stepwise into their chemotherapy regi-

men. Exposure to imatinib was increased progressively in five patient cohorts that received the agent from 42 to 280 days before maintenance therapy. Ph- ALL patients (N = 65) who received the same chemotherapy without imatinib were used as comparators. Patients with compatible sibling donors underwent BMT with imatinib given for 6 months following.

Summary: Continuous imatinib exposure improved outcome in patients in the fifth cohort with a 3-year eventfree survival (EFS) of 80% ± 11% (95% CI, 64%-90%). Three-year EFS was similar for patients in the fifth cohort treated with chemotherapy plus imatinib (88% ± 11%; 95% CI, 66%96%) or sibling-donor BMT (57% ± 22%; 95% CI, 30.4%-76.1%). No appreciable increase in toxicities was associated with adding imatinib to intensive chemotherapy. Takeaway: Imatinib added to intensive chemotherapy improved 3-year EFS in children and adolescents with Ph+ ALL. Outcomes were not superior when imatinib plus chemotherapy was added to BMT. Schultz KR, et al; for the Children’s Oncology Group. J Clin Oncol. 2009 Oct 5. Epub ahead of print. ■ Hormonal Therapy for Prostate Cancer and Comorbid Conditions Background: Hormonal therapy (HT), when combined with external beam radiation therapy (RT), improves cancer-specific and overall survival versus RT alone. A recent postrandomization hypothesis-generating analysis suggested that men with moderate to severe comorbidity did not receive this survival benefit. Which condition(s) eliminates this benefit was not determined. Design: Risk of all-cause mortality was measured by Cox regression in 5077 men (median age, 69.5 years) with localized or locally advanced prostate cancer. The patients were treated with or without a median of 4 months of neoadjuvant HT followed by RT. Summary: Neoadjuvant HT use was not associated with an increased risk of all-cause mortality in men with no comorbidity (9.6% vs 6.7%, adjusted HR, 0.97; 95% CI, 0.72-1.32; P = .86) or a single coronary artery disease (CAD) risk factor (10.7% vs 7.0%, adjusted HR, 1.04; 95% CI, 0.75-1.43; P = .82) after median follow-ups of 5.0 and 4.4 years, respectively. However, for men with CAD-induced congestive heart failure (CHF) or myocardial infarction (MI), after a median follow-up of 5.1 years, neoadjuvant HT use was significantly associated with an increased risk of all-cause mortality (26.3% vs 11.2%, adjusted HR, 1.96; 95% CI, 1.04-3.71; P = .04). Takeaway: Neoadjuvant HT use is significantly associated with all-cause mortality among men with a history of CAD-induced CHF or MI. No association was found among men with no comorbidity or a single CAD risk factor. Nanda A, et al. JAMA. 2009;302: 866-873. ●

(29% vs. 21%), and chills (13% vs. 4%). Detailed safety data collection in these studies was primarily limited to Grade 3 and 4 adverse reactions and serious adverse reactions. In Study 7, a review of cardiac toxicity determined that supraventricular arrhythmias or tachycardia accounted for most of the difference in cardiac disorders (4.5% for R-CHOP vs. 1.0% for CHOP). The following Grade 3 or 4 adverse reactions occurred more frequently among patients in the R-CHOP arm compared with those in the CHOP arm: thrombocytopenia (9% vs. 7%) and lung disorder (6% vs. 3%). Other Grade 3 or 4 adverse reactions occurring more frequently among patients receiving R-CHOP were viral infection (Study 7), neutropenia (Studies 7 and 8), and anemia (Study 8). Immunogenicity As with all therapeutic proteins, there is a potential for immunogenicity. The observed incidence of antibody (including neutralizing antibody) positivity in an assay is highly dependent on several factors including assay sensitivity and specificity, assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to Rituxan with the incidence of antibodies to other products may be misleading. Using an ELISA assay, anti-human anti-chimeric antibody (HACA) was detected in 4 of 356 (1.1%) patients with low-grade or follicular NHL receiving singleagent Rituxan. Three of the four patients had an objective clinical response. The clinical relevance of HACA formation in Rituxan-treated patients is unclear. Postmarketing Experience The following adverse reactions have been identified during post-approval use of Rituxan in hematologic malignancies. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Decisions to include these reactions in labeling are typically based on one or more of the following factors: (1) seriousness of the reaction, (2) frequency of reporting, or (3) strength of causal connection to Rituxan. Hematologic: prolonged pancytopenia, marrow hypoplasia, and late-onset neutropenia, hyperviscosity syndrome in Waldenstrom’s macroglobulinemia. Cardiac: fatal cardiac failure. Immune/Autoimmune Events: uveitis, optic neuritis, systemic vasculitis, pleuritis, lupus-like syndrome, serum sickness, polyarticular arthritis, and vasculitis with rash. Infection: viral infections, including progressive multifocal leukoencephalopathy (PML), increase in fatal infections in HIV-associated lymphoma, and a reported increased incidence of Grade 3 and 4 infections in patients with previously treated lymphoma without known HIV infection. Neoplasia: disease progression of Kaposi’s sarcoma. Skin: severe mucocutaneous reactions. Gastrointestinal: bowel obstruction and perforation. Pulmonary: fatal bronchiolitis obliterans and pneumonitis (including interstitial pneumonitis). DRUG INTERACTIONS Formal drug interaction studies have not been performed with Rituxan. USE IN SPECIFIC POPULATIONS Pregnancy Category C: There are no adequate and well-controlled studies of rituximab in pregnant women. Postmarketing data indicate that B-cell lymphocytopenia generally lasting less than six months can occur in infants exposed to rituximab in-utero. Rituximab was detected postnatally in the serum of infants exposed in-utero. Non-Hodgkin’s lymphoma is a serious condition that requires treatment. Rituximab should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus. Reproduction studies in cynomolgus monkeys at maternal exposures similar to human therapeutic exposures showed no evidence of teratogenic effects. However, B-cell lymphoid tissue was reduced in the offspring of treated dams. The B-cell counts returned to normal levels, and immunologic function was restored within 6 months of birth. Nursing Mothers It is not known whether Rituxan is secreted into human milk. However, Rituxan is secreted in the milk of lactating cynomolgus monkeys, and IgG is excreted in human milk. Published data suggest that antibodies in breast milk do not enter the neonatal and infant circulations in substantial amounts. The unknown risks to the infant from oral ingestion of Rituxan should be weighed against the known benefits of breastfeeding. Pediatric Use The safety and effectiveness of Rituxan in pediatric patients have not been established. Geriatric Use Diffuse Large B-Cell NHL Among patients with DLBCL evaluated in three randomized, active-controlled trials, 927 patients received Rituxan in combination with chemotherapy. Of these, 396 (43%) were age 65 or greater and 123 (13%) were age 75 or greater. No overall differences in effectiveness were observed between these patients and younger patients. Cardiac adverse reactions, mostly supraventricular arrhythmias, occurred more frequently among elderly patients. Serious pulmonary adverse reactions were also more common among the elderly, including pneumonia and pneumonitis. Low-Grade or Follicular Non-Hodgkin’s Lymphoma Clinical studies of Rituxan in low-grade or follicular, CD20-positive, B-cell NHL did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger subjects. OVERDOSAGE There has been no experience with overdosage in human clinical trials. Single doses of up to 500 mg/m2 have been given in dose-escalation clinical trials. NONCLINICAL TOXICOLOGY Carcinogenesis, Mutagenesis, Impairment of Fertility No long-term animal studies have been performed to establish the carcinogenic or mutagenic potential of Rituxan, or to determine potential effects on fertility in males or females. PATIENT COUNSELING INFORMATION Patients should be provided the Rituxan Medication Guide and provided an opportunity to read prior to each treatment session. Because caution should be exercised in administering Rituxan to patients with active infections, it is important that the patient’s overall health be assessed at each visit and the risks of Rituxan therapy and any questions resulting from the patient’s reading of the Medication Guide be discussed. Rituxan is detectable in serum for up to six months following completion of therapy. Individuals of childbearing potential should use effective contraception during treatment and for 12 months after Rituxan therapy.

Retreatment

Previously untreated follicular, CD20-positive, B-cell NHL in combination with CVP chemotherapy Across DLBCL trials in patients ≥60 years of age, the following Grade 3 or 4 adverse reactions were reported more frequently among patients in the R-CHOP arm compared with those in the CHOP arm: thrombocytopenia (9% vs 7%) and lung disorder (6% vs 3%). Other Grade 3 or 4 adverse reactions reported more frequently among patients receiving R-CHOP were viral infection and neutropenia. In the Marcus trial of first-line follicular NHL, patients in the R-CVP arm had higher incidences of infusional toxicity (71% vs 51%) and Grade 3–4 neutropenia (24% vs 14%) as compared with those in the CVP arm. In the E1496 trial of low-grade NHL, neutropenia was the only Grade 3 or 4 adverse event that occurred more frequently (≥2%) in the RITUXAN arm compared with those who received no further therapy (4% vs 1%).
