INTRODUCTION

New Drug Approvals in 2011: Novel Therapies Mark a Year of Increased FDA Approvals Gary M. Owens, MD President, Gary Owens Associates

T

he year 2011 was one of change and optimism for the pharmaceutical industry as a result of the 30 new drugs that were approved by the US Food and Drug Administration (FDA). The 30 approvals, which included 24 new molecular entities and 6 biologics, is the highest number of drugs approved in 1 year since 2004, when 36 agents were approved by the FDA (Figure).1 This group includes many novel agents that will help fill substantial unmet needs for patients. Topping the list of 2011 FDA approvals were 8 new drugs for cancer, many with novel mechanisms of action. In addition, 2 new oral agents for the treatment of hepatitis C were introduced in 2011, as well as the first new drug in 50 years for the treatment of lupus. In 2011, we also saw approval of traditional, small-molecule products in categories such as anticoagulants, seizure disorders, and chronic obstructive pulmonary disease (COPD). Overall, 2011 could be considered a year of significant progress for drug approvals. But, does this represent a trend in the FDA process, coupled with increasing output of industry research and development (R&D) processes? Will this be a one-time event in a general downward trend in new FDA approvals?

Notable Changes in 2011 There were a number of significant milestones in 2011 in addition to the increased number of drugs approved, including: 1. The majority of drugs approved by the FDA in 2011 received priority review. The priority review process gives the FDA a 6-month goal to complete its evaluation for safety and effectiveness. This process can substantially shorten the time to approval. According to the FDA, priority review requires that additional attention and resources be directed to drugs that have the potential to provide significant advances in treatment. Such advances can be demonstrated by2: • Evidence of increased effectiveness in treatment, prevention, or diagnosis of disease • Elimination or substantial reduction of a treatmentlimiting drug reaction

• Documented enhancement of a patient’s willingness or ability to take the drug according to the required schedule and dose • Evidence of safety and effectiveness in a new subpopulation, such as children 2. Of the new approvals, 19 (~66%) drugs did not require their manufacturers to provide additional information to the FDA, so their reviews were completed in a single cycle3 3. Approximately 70% of the new drugs were approved in the United States before any other country, including the European Union3 4. Almost every new drug approval was on or before the Prescription Drug User Fee Act date.3 In general, the FDA met its goals of improving the timeliness of drug reviews, and there were relatively few surprise delays in approval.

A Decade of Change The past decade has seen major changes in the pharmaceutical industry. Mergers and acquisitions in the pharmaceutical industry over the past 10 years have been the norm and a way to bolster underperforming R&D efforts. Of the 42 members of the Pharmaceutical Research and Manufacturers of America in 1988, only 11 remained in 2011.4 Although there has been a reranking of the top 10 pharmaceutical manufacturers based on market capitalization, 8 companies from 2001 remained on the list by 2011.5 The total market capitalization of the leading 10 pharmaceutical companies was lower in 2011 than in 2001, despite the total inflation rate of >25% over the same period.5 Of note, the cumulative dollars attributed to the top 10 drugs by sales amount rose during that period from $41 billion in 2001 to $76 billion in 2011.5 What has changed dramatically in the past decade is the composition of the top 10 drug list by sales. In 2001, that list was dominated by small-molecule blockbuster drugs, such as simvastatin (Zocor), atorvastatin (Lipitor), omeprazole (Prilosec), and amlodipine (Norvasc). By contrast, in 2011, 3 of the leading 10 drugs by sales were specialty products, namely, etaner-

cept (Enbrel), adalimumab (Humira), and infliximab (Remicade). This change is a reflection of the shift of developmental emphasis by the industry to complex molecules and specialty pharmaceuticals. Finally, there has been a shift in focus of drug development targets over the past decade. Cancer is now the largest therapeutic area of drug development, replacing traditional categories such as hypertension, hyperlipidemia, and dyspepsia. This shift may be largely a result of the availability of relatively inexpensive generics that are safe, effective, and broadly used in these categories.

Cancer Therapies Dominate As already noted, 8 new drugs for cancer were approved in 2011, targeting prostate cancer, lymphoma, leukemia, myelofibrosis, thyroid cancer, and melanoma, with many being first-in-class agents. For example, abiraterone (Zytiga) is the first oral drug approved for use in patients with castration-resistant prostate cancer. A phase 3 clinical trial demonstrated that for patients receiving abiraterone with prednisone after previous treatment with docetaxel, the overall survival (OS) rate improved from 10.9 months to 14.8 months. Ipilimumab (Yervoy) is the first drug in a class of immune-boosting agents for the treatment of malignant melanoma. Ipilimumab is a monoclonal antibody that blocks a molecule that downregulates the body’s immune system and limits its ability to fight tumor cells. Ruxolitinib (Jakafi) is the first of the Janus kinase inhibitors and is the first drug specifically approved for the treatment of myelofibrosis, a myeloproliferative disorder. Adcetris (brentuximab vedotin) is an antibody conjugate targeted to CD30, making the drug effective in patients with Hodgkin lymphoma and anaplastic largecell lymphoma. Vandetanib (Caprelsa), a tyrosine kinase inhibitor, is the first drug to be specifically approved for the treatment of medullary carcinoma of the thyroid. Additional cancer drugs approved in 2011 include asparaginase Erwinia chrysanthemi (Erwinaze), which is used to treat acute lymphoblastic leukemia; crizotinib (Xalkori); and vemurafenib (Zelboraf). Personalized Medicine Emerging The sequencing of the human genome ushered in the era of genomics in medicine. For the most part, the use of genetic testing to guide cancer therapy has been more promise than reality. But 2011 was a year of change in that respect as well. Two drugs were approved for use specifically with companion diagnostics. The first agent, crizotinib treats select patients with non–small-cell lung cancer (NSCLC) who express the abnormal anaplastic

lymphoma kinase (ALK) gene, which promotes cancer growth. Crizotinib was approved with a companion diagnostic test, the ALK Break-Apart FISH Probe Kit, to determine if the patient has the l ALK gene mutation, which occurs in approximately 1 of 20 patients with NSCLC. The diagnostic kit was approved simultaneously with crizotinib. The oral drug vemurafenib was the second FDAapproved agent for malignant melanoma in 2011. Like ipilimumab, vemurafenib demonstrated an improvement in OS in the phase 3 clinical trials. Vemurafenib is only effective in treating patients with advanced melanoma who have the BRAF V600E mutation. The genetic test, the cobas 4800 BRAF V600 mutation test, is a companion diagnostic for vemurafenib.

For the drug industry, 2011 certainly was an exciting year. Approvals of new drugs increased significantly, with the majority of approvals being for novel agents that offer first-in-class treatments for patients with life-threatening diseases. Crizotinib and vemurafenib—which are also designated as orphan drugs—may represent the beginning of a trend toward more targeted therapies that will be approved with accompanying diagnostic tests, allowing physicians to more effectively target the right patient for the right therapy.

Significant Therapeutic Advances in Other Categories Although cancer dominated drug approvals in 2011, other significant advances were apparent. For example, belimumab (Benlysta) is the first new treatment approved for systemic lupus erythematosus in more than 50 years. It is designed to target the B-lymphocyte stimulator (BLyS) protein. By decreasing the proliferation of BLyS, belimumab ultimately decreases the production of cells that can attack a patient’s vascularity and major organ systems. The 2 oral protease inhibitors telaprevir (Incivek) and boceprevir (Victrelis) represent a new class of agents for the treatment of hepatitis C virus infection. Hepatitis C is a silent, but often deadly, virus that can cause cirrhosis and liver failure and can increase a patient’s risk for liver cancer. These 2 drugs, used in combination with ribavirin and an interferon, offer the potential for improved treatment outcomes in patients with hepatitis C and the abil-

ity to re-treat selected patients who have previously not achieved virologic cure from standard therapies. Among the small-molecule agents, ticagrelor (Brilinta) is an oral antiplatelet drug approved for reducing the risk for cardiovascular mortality for patients with acute coronary syndrome. Rivaroxaban (Xarelto) is the first available oral direct factor Xa inhibitor. It can be taken once daily to reduce the risk for stroke in nonvalvular atrial fibrillation. Finally, roflumilast (Daliresp) is a new oral treatment for COPD. Roflumilast is the first phosphodiesterase type 4 inhibitor, and it targets patients with severe COPD.

Looking Forward For the drug industry, 2011 certainly was an exciting year. Approvals of new drugs increased significantly, with the majority of approvals being for novel agents that offer first-in-class treatments for patients with lifethreatening diseases. Although 1 year of increased FDA approvals does not make a trend, the fact that the majority of the agents were approved on first review suggests

improved communications between the FDA and the industry about the trial and data thresholds needed for approval. For example, 2012 has already seen the approval of 6 new specialty agents in the first quarter alone, including 3 cancer or cancer-related drugs. Did 2011 usher in a new era of novel drug approvals and industry growth? Only time will tell. â&#x2013; Author Disclosure Dr Owens is a consultant to Boston Scientific, CardioDX, Genentech, Genzyme, Johnson and Johnson, OncoMed Pharmaceuticals, and Towers Watson.

TESTES

Mechanism of action

Important Safety Information Contraindications—ZYTIGA® may cause fetal harm (Pregnancy Category X) and is contraindicated in women who are or may become pregnant. Hypertension, Hypokalemia, and Fluid Retention Due to Mineralocorticoid Excess—Use with caution in patients with a history of cardiovascular disease or with medical conditions that might be compromised by increases in hypertension, hypokalemia, and fluid retention. ZYTIGA® may cause hypertension, hypokalemia, and fluid retention as a consequence of increased mineralocorticoid levels resulting from CYP17 inhibition. Safety has not been established in patients with LVEF < 50% or New York Heart Association (NYHA) Class III or IV heart failure because these patients were excluded from the randomized clinical trial. Control hypertension and correct hypokalemia before and during treatment. Monitor blood pressure, serum potassium, and symptoms of fluid retention at least monthly. Adrenocortical Insufficiency (AI)—AI has been reported in clinical trials in patients receiving ZYTIGA® in combination with prednisone, after an interruption of daily steroids, and/or with concurrent infection or stress. Use caution and monitor for symptoms and signs of AI if prednisone is stopped or withdrawn, if prednisone dose is reduced, or if the patient experiences unusual stress. Symptoms and signs of AI may be masked by adverse reactions associated with mineralocorticoid excess seen in patients treated with ZYTIGA®. Perform appropriate tests, if indicated, to confirm AI.

Increased dosages of corticosteroids may be used before, during, and after stressful situations. Hepatotoxicity—Increases in liver enzymes have led to drug interruption, dose modification, and/or discontinuation. Monitor liver function and modify, withhold, or discontinue ZYTIGA® dosing as recommended (see Prescribing Information for more information). Measure serum transaminases [alanine aminotransferase (ALT) and aspartate aminotransferase (AST)] and bilirubin levels prior to starting treatment with ZYTIGA®, every two weeks for the first three months of treatment, and monthly thereafter. Promptly measure serum total bilirubin, AST, and ALT if clinical symptoms or signs suggestive of hepatotoxicity develop. Elevations of AST, ALT, or bilirubin from the patient’s baseline should prompt more frequent monitoring. If at any time AST or ALT rise above five times the upper limit of normal (ULN) or the bilirubin rises above three times the ULN, interrupt ZYTIGA® treatment and closely monitor liver function. Food Effect—ZYTIGA® must be taken on an empty stomach. Exposure of abiraterone increases up to 10-fold when abiraterone acetate is taken with meals. No food should be eaten for at least two hours before the dose of ZYTIGA® is taken and for at least one hour after the dose of ZYTIGA® is taken. Abiraterone C max and AUC 0-∞ (exposure) were increased up to 17- and 10-fold higher, respectively, when a single dose of abiraterone acetate was administered with a meal compared to a fasted state.

study in patients with metastatic castration-resistant prostate cancer (mCRPC) who had received prior chemotherapy containing docetaxel (N = 1,195). Patients were randomized 2:1 to receive ZYTIGA® 1,000 mg orally once daily + prednisone 5 mg orally twice daily (n = 797) or placebo orally once daily + prednisone 5 mg orally twice daily (n = 398). Patients were using a gonadotropin-releasing hormone (GnRH) agonist or were previously treated with orchiectomy and were at castration levels of testosterone (serum testosterone ≤ 50 ng/dL).1 The primary efficacy endpoint was overall survival. †552 events. ‡775 events. 08Z11121R3

Adverse Reactions—The most common adverse reactions (≥ 5%) are joint swelling or discomfort, hypokalemia, edema, muscle discomfort, hot flush, diarrhea, urinary tract infection, cough, hypertension, arrhythmia, urinary frequency, nocturia, dyspepsia, fractures and upper respiratory tract infection. Drug Interactions—ZYTIGA® is an inhibitor of the hepatic drug-metabolizing enzyme CYP2D6. Avoid coadministration with CYP2D6 substrates that have a narrow therapeutic index. If an alternative cannot be used, exercise caution and consider a dose reduction of the CYP2D6 substrate. Additionally, abiraterone is a substrate of CYP3A4 in vitro. Strong inhibitors and inducers of CYP3A4 should be avoided or used with caution. Use in Specific Populations—The safety of ZYTIGA® in patients with baseline severe hepatic impairment has not been studied. These patients should not receive ZYTIGA®.

ZYTIGA® (abiraterone acetate) Tablets Brief Summary of Prescribing Information. INDICATIONS AND USAGE ZYTIGA in combination with prednisone is indicated for the treatment of patients with metastatic castration-resistant prostate cancer (CRPC) who have received prior chemotherapy containing docetaxel. CONTRAINDICATIONS Pregnancy: ZYTIGA may cause fetal harm when administered to a pregnant woman. ZYTIGA is contraindicated in women who are or may become pregnant. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. WARNINGS AND PRECAUTIONS Hypertension, Hypokalemia and Fluid Retention Due to Mineralocorticoid Excess: Use ZYTIGA with caution in patients with a history of cardiovascular disease. ZYTIGA may cause hypertension, hypokalemia, and fluid retention as a consequence of increased mineralocorticoid levels resulting from CYP17 inhibition [see Adverse Reactions and Clinical Pharmacology (12.1) in full Prescribing Information]. Co-administration of a corticosteroid suppresses adrenocorticotropic hormone (ACTH) drive, resulting in a reduction in the incidence and severity of these adverse reactions. Use caution when treating patients whose underlying medical conditions might be compromised by increases in blood pressure, hypokalemia or fluid retention, e.g., those with heart failure, recent myocardial infarction or ventricular arrhythmia. The safety of ZYTIGA in patients with left ventricular ejection fraction <50% or NYHA Class III or IV heart failure has not been established because these patients were excluded from the randomized clinical trial. Monitor patients for hypertension, hypokalemia, and fluid retention at least once a month. Control hypertension and correct hypokalemia before and during treatment with ZYTIGA. Adrenocortical Insufficiency: Adrenocortical insufficiency has been reported in clinical trials in patients receiving ZYTIGA in combination with prednisone, following interruption of daily steroids and/or with concurrent infection or stress. Use caution and monitor for symptoms and signs of adrenocortical insufficiency, particularly if patients are withdrawn from prednisone, have prednisone dose reductions, or experience unusual stress. Symptoms and signs of adrenocortical insufficiency may be masked by adverse reactions associated with mineralocorticoid excess seen in patients treated with ZYTIGA. If clinically indicated, perform appropriate tests to confirm the diagnosis of adrenocortical insufficiency. Increased dosage of corticosteroids may be indicated before, during and after stressful situations [see Warnings and Precautions]. Hepatotoxicity: Marked increases in liver enzymes leading to drug discontinuation or dosage modification have occurred [see Adverse Reactions]. Measure serum transaminases (ALT and AST) and bilirubin levels prior to starting treatment with ZYTIGA, every two weeks for the first three months of treatment and monthly thereafter. In patients with baseline moderate hepatic impairment receiving a reduced ZYTIGA dose of 250 mg, measure ALT, AST, and bilirubin prior to the start of treatment, every week for the first month, every two weeks for the following two months of treatment and monthly thereafter. Promptly measure serum total bilirubin, AST, and ALT if clinical symptoms or signs suggestive of hepatotoxicity develop. Elevations of AST, ALT, or bilirubin from the patient’s baseline should prompt more frequent monitoring. If at any time AST or ALT rise above five times the ULN, or the bilirubin rises above three times the ULN, interrupt ZYTIGA treatment and closely monitor liver function. Re-treatment with ZYTIGA at a reduced dose level may take place only after return of liver function tests to the patient’s baseline or to AST and ALT less than or equal to 2.5X ULN and total bilirubin less than or equal to 1.5X ULN [see Dosage and Administration (2.2) in full Prescribing Information]. The safety of ZYTIGA re-treatment of patients who develop AST or ALT greater than or equal to 20X ULN and/or bilirubin greater than or equal to 10X ULN is unknown. Food Effect: ZYTIGA must be taken on an empty stomach. No food should be consumed for at least two hours before the dose of ZYTIGA is taken and for at least one hour after the dose of ZYTIGA is taken. Abiraterone Cmax and AUC0-∞ (exposure) were increased up to 17- and 10-fold higher, respectively, when a single dose of abiraterone acetate was administered with a meal compared to a fasted state. The safety of these increased exposures when multiple doses of abiraterone acetate are taken with food has not been assessed [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) in full Prescribing Information]. ADVERSE REACTIONS The following are discussed in more detail in other sections of the labeling: Hypertension, hypokalemia, and fluid retention due to mineralocorticoid excess [see Warnings and Precautions]. Adrenocortical insufficiency [see Warnings and Precautions]. Hepatotoxicity [see Warnings and Precautions]. Food effect [see Warnings and Precautions].

ZYTIGA® (abiraterone acetate) Tablets Clinical Trial 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 clinical practice. In a placebo-controlled, multicenter phase 3 clinical trial of patients with metastatic castration-resistant prostate cancer who were using a gonadotropin-releasing hormone (GnRH) agonist or were previously treated with orchiectomy, ZYTIGA was administered at a dose of 1,000 mg daily in combination with prednisone 5 mg twice daily in the active treatment arm (N = 791). Placebo plus prednisone 5 mg twice daily was given to control patients (N = 394). The median duration of treatment with ZYTIGA was 8 months. The most common adverse drug reactions (≥5%) reported in clinical studies were joint swelling or discomfort, hypokalemia, edema, muscle discomfort, hot flush, diarrhea, urinary tract infection, cough, hypertension, arrhythmia, urinary frequency, nocturia, dyspepsia, fractures and upper respiratory tract infection. The most common adverse drug reactions that resulted in drug discontinuation were aspartate aminotransferase increased, alanine aminotransferase increased, urosepsis and cardiac failure (each in <1% of patients taking ZYTIGA). Adverse reactions and laboratory abnormalities related to mineralocorticoid effects were reported more commonly in patients treated with ZYTIGA than in patients treated with placebo: hypokalemia 28% versus 20%, hypertension 9% versus 7% and fluid retention (edema) 27% versus 18%, respectively (see Table 1). In patients treated with ZYTIGA, grades 3 to 4 hypokalemia occurred in 5% of patients and grades 3 to 4 hypertension was reported in 1% of patients [see Warnings and Precautions]. Table 1 shows adverse reactions due to ZYTIGA that occurred with either a ≥ 2% absolute increase in frequency compared to placebo, or were events of special interest (mineralocorticoid excess, cardiac adverse reactions, and liver toxicities).

Drugs that Inhibit or Induce CYP3A4 Enzymes: Based on in vitro data, ZYTIGA is a substrate of CYP3A4. The effects of strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, nefazodone, saquinavir, telithromycin, ritonavir, indinavir, nelfinavir, voriconazole) or inducers (e.g., phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital) on the pharmacokinetics of abiraterone have not been evaluated, in vivo. Avoid or use with caution, strong inhibitors and inducers of CYP3A4 during ZYTIGA treatment [see Clinical Pharmacology (12.3) in full Prescribing Information].

Includes all fractures with the exception of pathological fracture Includes terms Arrhythmia, Tachycardia, Atrial fibrillation, Supraventricular tachycardia, Atrial tachycardia, Ventricular tachycardia, Atrial flutter, Bradycardia, Atrioventricular block complete, Conduction disorder, and Bradyarrhythmia 7 Includes terms Angina pectoris, Chest pain, and Angina unstable. Myocardial infarction or ischemia occurred more commonly in the placebo arm than in the ZYTIGA arm (1.3% vs. 1.1% respectively). 8 Includes terms Cardiac failure, Cardiac failure congestive, Left ventricular dysfunction, Cardiogenic shock, Cardiomegaly, Cardiomyopathy, and Ejection fraction decreased Cardiovascular Adverse Reactions: Cardiovascular adverse reactions in the phase 3 trial are shown in Table 1. The majority of arrhythmias were grade 1 or 2. Grade 3-4 arrhythmias occurred at similar rates in the two arms. There was one death associated with arrhythmia and one patient with sudden death in the ZYTIGA arm. No patients had sudden death or arrhythmia associated with death in the placebo arm. Cardiac ischemia or myocardial infarction led to death in 2 patients in the placebo arm and 1 death in the ZYTIGA arm. Cardiac failure resulting in death occurred in 1 patient on both arms. Hepatotoxicity: Drug-associated hepatotoxicity with elevated ALT, AST, and total bilirubin has been reported in patients treated with ZYTIGA. Across all clinical trials, liver function test elevations (ALT or AST increases of > 5X ULN) were reported in 2.3% of patients who received ZYTIGA, typically during the first 3 months after starting treatment. In the phase 3 trial, patients whose baseline ALT or AST were elevated were more likely to experience liver function test elevations than those beginning with normal values. When elevations of either ALT or AST > 5X ULN, or elevations in bilirubin > 3X ULN were observed, ZYTIGA was withheld or discontinued. In two instances marked increases in liver function tests occurred [see Warnings and Precautions]. These two patients with normal baseline hepatic function, experienced ALT or AST elevations 15 to 40X ULN and bilirubin elevations 2 to 6 X ULN. Upon discontinuation of ZYTIGA, both patients had normalization of their liver function tests and one patient was re-treated with ZYTIGA without recurrence of the elevations. In clinical trials, the following patients were excluded: patients with active hepatitis, patients with baseline ALT and/or AST ≥ 2.5X ULN in the absence of liver metastases, and patients with ALT and/or AST > 5X ULN in the presence of liver metastases. Abnormal liver function tests developing in patients participating in clinical trials were managed by treatment interruption, dose modification and/or discontinuation [see Dosage and Administration (2.2) in full Prescribing Information and Warnings and Precautions]. Patients with elevations of ALT or AST > 20X ULN were not re-treated. Other Adverse Reactions: Adrenal insufficiency occurred in two patients on the abiraterone arm of the phase 3 clinical trial (< 1%). Laboratory Abnormalities of Interest: Table 2 shows laboratory values of interest from the phase 3 placebo-controlled clinical trial. Grade 3-4 low serum phosphate (7.2%) and potassium (5.3%) occurred more frequently in the ZYTIGA arm. 6

DRUG INTERACTIONS Effects of Abiraterone on Drug Metabolizing Enzymes: ZYTIGA is an inhibitor of the hepatic drug-metabolizing enzyme CYP2D6. In a CYP2D6 drug-drug interaction trial, the Cmax and AUC of dextromethorphan (CYP2D6 substrate) were increased 2.8- and 2.9-fold, respectively, when dextromethorphan was given with abiraterone acetate 1,000 mg daily and prednisone 5 mg twice daily. Avoid co-administration of abiraterone acetate with substrates of CYP2D6 with a narrow therapeutic index (e.g., thioridazine). If alternative treatments cannot be used, exercise caution and consider a dose reduction of the concomitant CYP2D6 substrate drug [see Clinical Pharmacology (12.3) in full Prescribing Information]. In vitro, ZYTIGA was shown to inhibit the hepatic drug-metabolizing enzyme CYP2C8. There are no clinical data on the use of ZYTIGA with drugs that are substrates of CYP2C8.

USE IN SPECIFIC POPULATIONS Pregnancy: Pregnancy Category X [see Contraindications]. ZYTIGA is contraindicated in women who are or may become pregnant while receiving the drug. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus and the potential risk for pregnancy loss. Women of childbearing potential should be advised to avoid becoming pregnant during treatment with ZYTIGA. Nursing Mothers: ZYTIGA is not indicated for use in women. It is not known if abiraterone acetate 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 from ZYTIGA, a decision should be made to either discontinue nursing, or discontinue the drug taking into account the importance of the drug to the mother. Pediatric Use: ZYTIGA is not indicated in children. Geriatric Use: Of the total number of patients in a phase 3 trial of ZYTIGA, 71% of patients were 65 years and over and 28% were 75 years and over. No overall differences in safety or effectiveness were observed between these elderly patients and younger patients. Patients with Hepatic Impairment: The pharmacokinetics of abiraterone were examined in subjects with baseline mild (n = 8) or moderate (n = 8) hepatic impairment (Child-Pugh Class A and B, respectively) and in 8 healthy control subjects with normal hepatic function. The systemic exposure (AUC) of abiraterone after a single oral 1,000 mg dose of ZYTIGA increased by approximately 1.1-fold and 3.6-fold in subjects with mild and moderate baseline hepatic impairment, respectively compared to subjects with normal hepatic function. No dosage adjustment is necessary for patients with baseline mild hepatic impairment. In patients with baseline moderate hepatic impairment (ChildPugh Class B), reduce the recommended dose of ZYTIGA to 250 mg once daily. If elevations in ALT or AST >5X ULN or total bilirubin >3X ULN occur in patients with baseline moderate hepatic impairment, discontinue ZYTIGA treatment [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) in full Prescribing Information]. The safety of ZYTIGA in patients with baseline severe hepatic impairment has not been studied. These patients should not receive ZYTIGA. For patients who develop hepatotoxicity during treatment, interruption of treatment and dosage adjustment may be required [see Dosage and Administration (2.2) in full Prescribing Information, Warnings and Precautions, and Clinical Pharmacology (12.3) in full Prescribing Information]. Patients with Renal Impairment: In a dedicated renal impairment trial, the mean PK parameters were comparable between healthy subjects with normal renal function (N=8) and those with end stage renal disease (ESRD) on hemodialysis (N=8) after a single oral 1,000 mg dose of ZYTIGA. No dosage adjustment is necessary for patients with renal impairment [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) in full Prescribing Information]. OVERDOSAGE: There have been no reports of overdose of ZYTIGA during clinical studies. There is no specific antidote. In the event of an overdose, stop ZYTIGA, undertake general supportive measures, including monitoring for arrhythmias and cardiac failure and assess liver function. Storage and Handling: Store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F) [see USP controlled room temperature]. Based on its mechanism of action, ZYTIGA may harm a developing fetus. Therefore, women who are pregnant or women who may be pregnant should not handle ZYTIGA without protection, e.g., gloves [see Use in Specific Populations]. Manufactured by: Patheon Inc.

Ruxolitinib a New Oral Option for the Treatment of Patients with Intermediateor High-Risk Myelofibrosis Disorders By Rhonda Williams

M

yeloproliferative neoplasms (MPNs) are a group of closely related hematologic malignancies that arise from abnormal development and function of the body’s bone marrow cells. Primary myelofibrosis (PMF), polycythemia vera (PV), and essential thrombocythemia (ET) comprise the Philadelphia chromosome (Ph)-negative MPNs.1 Myelofibrosis (MF) can arise on its own, which is called PMF, or it can result from the progression of other MPNs, such as postpolycythemia vera MF (PPV-MF) and postessential thrombocythemia MF (PET-MF).1

The Burden of Disease and Its Impact MF is characterized by cytopenias, splenomegaly, poor quality of life, and shortened survival.1 Because chronic MPNs previously were not classified as hematologic malignancies, limited epidemiologic studies are available to estimate the incidence of MF. Multiple regional studies suggest that an estimated 6328 new cases of chronic myeloproliferative disorders (CMPDs as they were previously known) occurred in the US population in 2004.2 Of these patients, 45% had PV, 24% had ET, and 10% had PMF.2 The average annual age-adjusted incidence in the United States between 2001 and 2003 was 2.1 per 100,000 persons, with rates ranging among states from a low of 0.8 per 100,000 persons in Delaware to as high as 4.1 per 100,000 persons in Idaho.2 The incidence was significantly higher in males (2.6 per 100,000) than in females (1.8 per 100,000; P <.05).2 In addition, the incidence increased significantly with age, reaching 13.3 per 100,000 persons among individuals aged ≥80 years.2 Although appropriate treatment of patients with ET and PV is associated with prolonged survival, patients with symptomatic forms of PMF have a median survival of <5 years.1 The prognosis of MF is quite variable; however, those who develop anemia generally have a poorer prognosis. Patients with a good prognosis can live for many years without experiencing major symptoms, whereas those with a poor prognosis may have a significantly shorter survival. A small percentage of patients with MF can transform to acute myeloid leukemia, which is often difficult to treat and can be fatal.

AMERICAN HEALTH & DRUG BENEFITS

June 2012

Few treatment options exist for patients with MF. Until recently, the choice of treatment was often dictated by a patient’s symptoms and specific circumstances. Some patients with MF may remain symptom-free for many years, without undergoing treatment; however, monitoring for any signs or symptoms that may suggest worsening of the disease is required. For patients who require symptomatic treatment, chemotherapeutic agents, immunomodulatory drugs, and biological response modifiers (eg, hydroxyurea, androgen therapies, corticosteroids, thalidomide, lenalidomide, and interferon) are often used. It is important to note that these therapies are not always directed to the biological processes that underlie the origin of disease or lead to progression of PMF. Therefore, these strategies are often primarily palliative in nature, and their effect on survival is uncertain. Finally, surgery or radiation therapy may also be used in those who fail to respond to other treatments. For many patients with MF, however, available treatments may be ineffective and allogeneic stem-cell transplantation may be the only potential known cure. A decisive advance in our understanding of the underlying molecular mechanisms of MPNs has been the discovery of a somatic gain-of-function point mutation in the Janus kinase (JAK) 2 gene, which is a common clinical feature in patients with ET, PV, and PMF.3,4 We now know that approximately 50% of patients with MF have a gain-of-function mutation in the JAK2 gene.5,6 Discoveries in the molecular pathogenesis of PV, ET, and PMF enabled the genetic classification and molecular diagnosis of these neoplasms. The World Health Organization diagnostic criteria, which were based largely on clinical and pathologic descriptions, were subsequently revised for PV, ET, and PMF to include the incorporation of testing for JAK2 and other genetic mutations.7 In addition to modifying the criteria for diagnosing, monitoring, and assessing patients with ET, PV, and PMF, the discovery of JAK2 involvement in patients with MF also led to the development of small-molecule inhibitors that specifically target JAK2. Although JAK2 mutations are responsible for the majority of dysregulat-

ed signaling in Ph-negative MPNs, JAK1 and JAK2 may interact, resulting in their transactivation.8,9 Armed with this information and a greater understanding of the cellular and molecular events that lead to the development of PMF, the possibility of more targeted and effective therapies for this disorder has become a reality. In November 2011, the US Food and Drug Administration (FDA) granted marketing approval of oral Jakafi (ruxolitinib) tablets for the treatment of patients with intermediate- or high-risk MF, including PMF, PPV-MF, and PET-MF.10

Clinical Pharmacology Mechanism of Action Jakafi, a kinase inhibitor, inhibits the Janus-associated kinases JAK1 and JAK2, which mediate the signaling of a number of cytokines and growth factors that are important for hematopoiesis and immune function. JAK signaling involves recruitment of signal transducers and activators of transcription (STATs) to cytokine receptors, activation, and subsequent localization of STATs to the nucleus, leading to modulation of gene expression.10 MF is known to be associated with dysregulated JAK1 and JAK2 signaling. In a mouse model of JAK2V617Fpositive MPN, oral administration of ruxolitinib prevented splenomegaly, preferentially decreased JAK2V617F mutated cells in the spleen, and decreased circulating inflammatory cytokines (eg, tumor necrosis factor–alpha and interleukin-6).10 Pharmacodynamics. In healthy persons and in patients with MF, ruxolitinib inhibited cytokine-induced STAT3 phosphorylation in whole blood. The maximal inhibition of STAT3 phosphorylation occurred 2 hours after dosing, returning to near-baseline levels by 10 hours in both groups of people. Pharmacokinetics. Maximal plasma concentration (Cmax) of ruxolitinib occurred 1 to 2 hours after oral administration. Pharmacokinetic studies demonstrated no evident food effect on the absorption of ruxolitinib; when administered with a high-fat meal, the mean Cmax decreased moderately (24%) and the area under the curve remained nearly unchanged (ie, 4% increase). In early clinical trials, the volume of distribution at steady state was between 53 L and 65 L in patients with MF.10 Phase 3 Clinical Trials Jakafi was approved by the FDA based on the results of 2 randomized, phase 3 trials (Study 1 and Study 2) conducted in patients with MF.10 These trials are described in detail in the product prescribing information, with key data highlighted in this article.

Trial Designs Study 1 was a randomized, double-blind trial that compared ruxolitinib with placebo in patients with MF who were refractory to or were not candidates for available therapy. The primary end point was the proportion of patients achieving a reduction in spleen volume of >35% from baseline at week 24, as measured by magnetic resonance imaging (MRI) or computed tomography (CT). Secondary end points included the duration of >35% reduction in spleen volume from baseline and the proportion of patients with a >50% reduction in Total Symptom Score from baseline to week 24. The latter was measured using the modified Myelofibrosis Symptom Assessment Form (MFSAF) v2.0 diary.10

In November 2011, the FDA approved ruxolitinib for the treatment of patients with intermediate- or high-risk MF, including PMF, PPV-MF, and PET-MF. Study 2 was a randomized, open-label trial that compared ruxolitinib with the best available therapy in patients with MF. The study investigators selected the best available therapy on a patient-by-patient basis, with the most frequently used agents, including hydroxyurea (N = 47%) and glucocorticoids (N = 16%). The primary end point of this trial was similar to that in Study 1—the proportion of patients achieving a reduction in spleen volume of >35% from baseline, but at week 48 (as measured by MRI or CT). The secondary end point of Study 2 was the proportion of patients achieving a >35% reduction in spleen volume from baseline to week 24.10 In both trials, patients were required to have palpable splenomegaly >5 cm below the costal margin, as well as an MF risk category of intermediate-2-risk (2 prognostic factors) or high-risk (>3 prognostic factors).10 Dosing in these trials was based on platelet counts. The starting dose of ruxolitinib was 15 mg administered orally twice daily in patients with baseline platelet counts of 100 to 200 ⳯ 109/L and 20 mg administered orally twice daily in patients with baseline platelet counts >200 ⳯ 109/L. The doses of ruxolitinib were then adjusted during the course of therapy based on efficacy and tolerability. Maximum doses based on platelet counts were as follows10: • Platelet count 100 to ≤125 ⳯ 109/L: 20 mg twice daily • Platelet count 75 to ≤100 ⳯ 109/L: 10 mg twice daily • Platelet count 50 to ≤75 ⳯ 109/L: 5 mg twice daily.

pared with either placebo (41.9% vs 0.7%, respectively; P <.001) or best available therapy (28.5% vs 0%, respectively; P <.001).10 In Study 1, a secondary end point was improvement in symptoms, as measured by the MFSAF v2.0. This scale captures MF-related symptoms, including abdominal discomfort, pain under the left ribs, night sweats, itching, bone or muscle pain, and early satiety. A higher proportion of ruxolitinib-treated patients experienced a ≥50% reduction in Total Symptom Score compared with placebo (45.9% vs 5.3%, respectively; P <.001). The median time to symptom response was <4 weeks.10

Safety Profile Because clinical trials are conducted under widely varying conditions, rates of adverse reactions observed in the clinical trials of a particular drug cannot be compared directly with rates observed in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The safety of ruxolitinib was assessed in 617 patients in 6 clinical studies with a median duration of follow-up of 10.9 months, including 301 patients with MF in 2 phase 3 studies. In these 2 studies, patients had a median duration of exposure to ruxolitinib of 9.5 months (range, 0.5-17 months), with 88.7% of patients treated for >6 months and 24.6% treated for >12 months. A total of 111 patients started treatment at 15 mg orally twice daily and 190 patients started at 20 mg orally twice daily.10 The most often reported adverse events were thrombocytopenia and anemia; the most frequent nonhematologic adverse events were bruising, dizziness, and headache.9 A total of 11.0% of patients receiving ruxolitinib and 10.6% of patients receiving placebo discontinued therapy because of adverse events.9 The rates of adverse reactions and laboratory abnormalities reported in Study 1 are summarized in Table 3. The median time to onset of grade 2 or higher anemia was approximately 6 weeks. Mean decreases in hemoglobin of 1.5 to 2 g/dL below baseline after 8 to 12 weeks of therapy were reported in ruxolitinib-treated patients, recovering gradually to reach a new steady state of approximately 1.0 g/dL below baseline.10 The median time to onset of grade 3 or 4 thrombocytopenia was approximately 8 weeks. Patients with baseline platelet counts of 100 to 200 ⳯ 109/L experienced a higher incidence of grade 3 or 4 thrombocytopenia than did those with baseline platelet counts >200 ⳯ 109/L.10 Dosing Ruxolitinib is dosed orally and can be administered with or without food. If a dose is missed, the patient should not take an additional dose, but should take the

next usual prescribed dose. When discontinuing ruxolitinib therapy for reasons other than thrombocytopenia, gradual tapering of the dose may be considered—for example, by 5 mg twice daily each week.10 In patients who are unable to ingest tablets, ruxolitinib can be administered through a nasogastric tube (8 French or greater) by suspending 1 tablet in approximately 40 mL of water and stirring for approximately 10 minutes. Within 6 hours after the tablet has dispersed, the suspension can be administered via a nasogastric tube using an appropriate syringe. After use, the tube should be rinsed with approximately 75 mL of water. The effect of tube-feeding preparations on ruxolitinib exposure during administration through a nasogastric tube has not been evaluated.10 The recommended starting dose of ruxolitinib is based on platelet count (Table 4). A complete blood count (CBC) and platelet count must be performed prior to initiating therapy, every 2 to 4 weeks until doses are stabilized, and then as clinically indicated. Doses may be titrated based on safety and efficacy.10 Treatment with ruxolitinib should be interrupted in patients with platelet counts <50 ⳯ 109/L. Once the platelet count recovers to >50 ⳯ 109/L, dosing may be restarted or increased following recovery of platelet counts to acceptable levels. Table 5 shows the maximum allowable dose that may be used when restarting ruxolitinib therapy following a previous interruption.10 Patients who develop anemia may require blood transfusions. Dose modifications of ruxolitinib in patients who develop anemia may also be considered.10 Neutropenia (absolute neutrophil count [ANC] <0.5 ⳯ 109/L) was generally reversible and was managed by temporarily withholding ruxolitinib. CBCs should be monitored as clinically indicated, with dosing adjusted as required.10

Dose Modification Based on Response If efficacy is considered insufficient and platelet and neutrophil counts are adequate, doses may be increased in 5-mg twice-daily increments to a maximum of 25 mg twice daily. Doses should not be increased during the first 4 weeks of therapy and not more often than every 2 weeks. Discontinue treatment after 6 months if no reduction in spleen size or symptom improvement is observed since initiation of ruxolitinib therapy.10 Based on limited clinical data, long-term maintenance with a 5-mg twice-daily dose has not demonstrated responses, and continued use of this dose should be limited to patients in whom the benefits outweigh the potential risks.10 Dose increases may be considered in patients who meet all of the following criteria10:

Contraindications, General Warnings, and Precautions There are no black box warnings or contraindications associated with the use of ruxolitinib. Warnings and precautions associated with use of the agent include such hematologic adverse reactions as thrombocytopenia, anemia, and neutropenia. As indicated earlier, a CBC and platelet count must be performed prior to initiating therapy with ruxolitinib. In clinical trials, patients with platelet counts <200 ⳯ 109/L at the start of therapy were more likely to develop thrombocytopenia during treatment. Thrombocytopenia was generally reversible, however, and was usually managed by modifying or interrupting the dose of ruxolitinib in clinical trials. Patients may also require a platelet transfusion, if clinically indicated. Dose reductions should be considered if platelet counts decrease, with the goal being to avoid dose interruptions for thrombocytopenia (Table 6).10 Patients should be assessed for the risk of developing serious bacterial, mycobacterial, fungal, and viral infections. Active serious infections should have resolved prior to initiating ruxolitinib therapy. Physicians should carefully observe patients receiving ruxolitinib for signs and symptoms of infection, and should initiate appropriate treatment promptly. Physicians should inform patients about early signs and symptoms of herpes zoster, and should advise patients to seek treatment as early as possible. ■ References

An Overview of Metastatic CastrationResistant Prostate Cancer and Treatment Prostate cancer is the most commonly diagnosed cancer in men, aside from skin cancer The American Cancer Society estimates that more than 241,000 new cases of prostate cancer will be diagnosed in 2012, representing approximately 1 in 4 new cases of cancer in US men.2 National prevalence of metastatic CRPC (mCRPC) has been estimated to be approximately 35,000. Prostate cancer was the second most common cause of cancer death among US men in 2009 and will be associated with approximately 28,000 deaths this year.2,3

Treatment options for mCRPC For more than half a century, suppressing androgens—in particular, testosterone—has remained the focus of treatment for metastatic prostate cancer.7 Various androgen deprivation approaches have been developed, including orchiectomy and treatment with gonadotropin-releasing hormone (GnRH) analogs, with or without antiandrogens. Both types of ADT target the testes as the primary site of androgen synthesis, but do not affect androgen production by the adrenals or in prostatic tumor tissue.1

Castration-resistant prostate cancer, defined The term castration-resistant describes disease that is progressing despite castrate levels of testosterone.4,5 Clinically, metastatic CRPC may present as an increase in prostate-specific antigen (PSA) or the appearance of new metastases and/or clinical symptoms after treatment with androgen deprivation therapy (ADT); one or both of these clinical features may be present.5 When CRPC presents with metastases, it is known as metastatic castration-resistant prostate cancer, or mCRPC. Patients with mCRPC may be symptomatic or asymptomatic.4,6

The adrenal glands are better known for their ability to produce hormones for regulation of metabolism, such as adrenaline.8 However, they also produce androgens, including androstenedione, dehydroepiandrosterone (DHEA), and dehydroepiandrosterone-sulphate (DHEA-S). These androgens are the precursors to testosterone, which is further converted to dihydrotestosterone (DHT).9,10

In mCRPC, the tumor may remain androgen sensitive Recent clinical evidence suggests that prostate cancer tumor cells may use multiple mechanisms to adapt to a low-androgen environment. Two such mechanisms are

cellular hypersensitivity and intratumoral androgen production.11-13 Cellular hypersensitivity can be achieved through a mutation in which tumor cells become hypersensitive to androgen by increasing the supply of androgen receptors (ARs), thereby improving the cells’ androgen capture rate. Adaptive mechanisms (such as AR mutation and AR overexpression) contribute to tumor sensitivity to androgen. Such cellular hypersensitivity increases the stimulatory effects of even low levels of testosterone and DHT.14,15

The second of these mechanisms, and perhaps the more astonishing, is the tumor’s ability to produce its own supply of androgen.1 Cellular mutations enable the tumor to recruit locally available androgen and androgen precursors and convert them, enzymatically, into testosterone and DHT; this cultivates a supply of

Additions to the treatment options after diagnosis of symptomatic mCRPC Standard treatment for patients with symptomatic mCRPC is chemotherapy with docetaxel in combination with prednisone.4 Over the past few years, 2 additional treatments that may improve the overall survival of patients with mCRPC have been approved in the United States—the taxane cabazitaxel (Jevtana®; sanofi-aventis) and abiraterone acetate (Zytiga®; Janssen Biotech, Inc.). Cabazitaxel, in combination with prednisone, is indicated for patients with mCRPC who have received treatment with docetaxel.20 Abiraterone acetate with prednisone is also indicated for men with mCRPC who have received treatment with docetaxel; however, unlike cabazitaxel (and docetaxel, for that matter), abiraterone acetate is not a chemotherapy, but rather an oral oncolytic 17αhydroxylase/C17,20-lyase (CYP17) inhibitor.1,21 We will talk more about a treatment option for patients with mCRPC, post-docetaxel.


ZYTIGA速 (abiraterone acetate) in combination with prednisone is indicated for the treatment of metastatic castration-resistant prostate cancer (CRPC) post-docetaxel. Abiraterone acetate, converted in vivo to abiraterone, inhibits CYP17, which directly affects the androgen biosynthesis pathway. This enzyme, which is expressed in testicular, adrenal, and prostatic tumor tissues, is required to produce androgen. With treatment, androgen biosynthesis may be inhibited at 3 sources.1

Mechanism of action Abiraterone acetate, converted to abiraterone in vivo, is an androgen biosynthesis inhibitor that directly affects the androgen biosynthesis pathway by inhibiting CYP17. The CYP17 enzyme, which is expressed in testicular, adrenal, and prostatic tumor tissues, is required to produce androgen.1 Consequently, androgen biosynthesis is inhibited at 3 sources of testosterone production: the testes, adrenal glands, and prostate tumor tissue.1 Hypertension, hypokalemia, and fluid retention due to mineralocorticoid excess Abiraterone acetate should be used with caution in patients with a history of cardiovascular disease. Abiraterone acetate may cause hypertension, hypokalemia, and fluid retention as a consequence of increased mineralocorticoid levels resulting from CYP17 inhibition. Coadministration of a corticosteroid suppresses adrenocorticotropic hormone drive, resulting in a reduction in the incidence and severity of these adverse reactions. Use caution when treating patients whose underlying medical conditions may be compromised by increases in blood pressure, hypokalemia, or fluid retention (eg, those with heart failure, recent myocardial infarction, or ventricular arrhythmia). The safety of abiraterone acetate in patients with left ventricular ejection fraction less than

Important Safety Information Contraindications - ZYTIGA® (abiraterone acetate) may cause fetal harm (Pregnancy Category X) and is contraindicated in women who are or may become pregnant. Hypertension, Hypokalemia and Fluid Retention Due to Mineralocorticoid Excess - Use with caution in patients with a history of cardiovascular disease or with medical conditions that might be compromised by increases in hypertension, hypokalemia, and fluid retention. ZYTIGA® may cause hypertension, hypokalemia, and fluid retention as a consequence of increased mineralocorticoid levels resulting from CYP17 inhibition. Safety has not been established in patients with LVEF <50% or New York Heart Association (NYHA) Class III or IV heart failure because these patients were excluded from the randomized clinical trial. Control hypertension and correct hypokalemia before and during treatment. Monitor blood pressure, serum potassium, and symptoms of fluid retention at least monthly. Adrenocortical Insufficiency (AI) - AI has been reported in clinical trials in patients receiving ZYTIGA® in combination with prednisone, after an interruption of daily steroids and/or with concurrent infection or stress. Use caution and monitor for symptoms and signs of AI if prednisone is stopped or withdrawn, if prednisone dose is reduced, or if the patient experiences unusual stress. Symptoms and signs of AI may be masked by adverse reactions associated with mineralocorticoid excess seen in patients treated with ZYTIGA®. Perform appropriate tests, if indicated, to confirm AI. Increased dosages of corticosteroids may be used before, during, and after stressful situations. Hepatotoxicity - Increases in liver enzymes have led to drug interruption, dose modification, and/or discon-

tinuation. Monitor liver function and modify, withhold, or discontinue ZYTIGA® dosing as recommended (see Prescribing Information for more information). Measure serum transaminases (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]) and bilirubin levels prior to starting treatment with ZYTIGA®, every two weeks for the first three months of treatment, and monthly thereafter. Promptly measure serum total bilirubin, AST, and ALT if clinical symptoms or signs suggestive of hepatotoxicity develop. Elevations of AST, ALT, or bilirubin from the patient’s baseline should prompt more frequent monitoring. If at any time AST or ALT rise above five times the upper limit of normal (ULN) or the bilirubin rises above three times the ULN, interrupt ZYTIGA® treatment and closely monitor liver function. Food Effect - ZYTIGA® must be taken on an empty stomach. Exposure of abiraterone increases up to 10-fold when abiraterone acetate is taken with meals. No food should be eaten for at least two hours before the dose of ZYTIGA® is taken and for at least one hour after the dose of ZYTIGA® is taken. Abiraterone Cmax and AUC0-∞ (exposure) were increased up to 17- and 10-fold higher, respectively, when a single dose of abiraterone acetate was administered with a meal compared to a fasted state. Adverse Reactions - The most common adverse reactions (≥5%) are joint swelling or discomfort, hypokalemia, edema, muscle discomfort, hot flush, diarrhea, urinary tract infection, cough, hypertension, arrhythmia, urinary frequency, nocturia, dyspepsia, fractures, and upper respiratory tract infection. Drug Interactions - ZYTIGA® is an inhibitor of the hepatic drug-metabolizing enzyme CYP2D6. Avoid

coadministration with CYP2D6 substrates that have a narrow therapeutic index. If an alternative cannot be used, exercise caution and consider a dose reduction of the CYP2D6 substrate. Additionally, abiraterone is a substrate of CYP3A4 in vitro. Strong inhibitors and inducers of CYP3A4 should be avoided or used with caution. Use in Specific Populations - The safety of ZYTIGA® in patients with baseline severe hepatic impairment has not been studied. These patients should not receive ZYTIGA®. 08Z11121R3

Conclusion The prevalence of mCRPC was estimated to be approximately 35,000 in 2009.3 As prostate cancer disease becomes more advanced, fewer treatment options are available. Until recently, therapeutic options for mCRPC were limited to treatment with the chemotherapy docetaxel as the standard treatment. However, despite castrate levels of androgens, some tumors remain androgen sensitive.11-13,15 Abiraterone acetate inhibits the CYP17 enzyme, which directly affects the androgen biosynthesis pathway. This enzyme, which is expressed in testicular, adrenal, and prostatic tumor tissues, is required to produce androgen.1 Results of the pivotal study for this agent demonstrate that patients receiving abiraterone acetate plus prednisone achieved a statistically significant difference in median OS compared with those receiving placebo with prednisone.1 Androgen biosynthesis inhibition, along with other classes of therapy already commercialized and under investigation, holds promise for the future of men with mCRPC who have received treatment with docetaxel. ■ References

PERSPECTIVE

Patients’ Impact on Quality Ratings: Are the Stars Aligned in Your Favor? Schumarry Chao, MD, MBA

O

ver the past few years, the treatment options for metastatic castration-resistant prostate cancer (mCRPC) have grown from 1 (docetaxel) to 4. In addition, a number of investigational drugs with new mechanisms of action have the potential for making additional inroads on this advanced stage of the disease. With the advent of these new—and expensive—treatments, P&T committee members have had to become experts on mCRPC quickly. In the absence of head-tohead trials, committees have become well versed on the clinical profiles of the various new agents: their mechanisms of action, survival benefits, tolerability profiles, delivery, dosing convenience, and the likelihood for compliance/persistence. As committees strive to find the right balance of access and cost, they need to also stay abreast of new information, such as rapidly evolving evidence-based guidelines. In addition to the boilerplate issues described above, there is another consideration that managed care organizations will need to factor into the mix: patient satisfaction. Per the Patient Protection and Affordable Care Act, how patients feel about their plan—as scored by the Medicare Health Outcomes Survey and the Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey—is a critical component of plan performance. Results of these surveys, along with other tools that capture consumer sentiment and overall performance, determine the number of stars awarded to a plan by the Medicare Star Quality Rating System (MSQRS). To the payer, the importance of the MSQRS is already being felt, as consumers are increasingly using the stars system to help them select the plan they will sign with and stay with. Starting in 2012, however, the impact of the MSQRS on our industry will be felt financially, as stars ratings will determine which plans can offer year-round enrollment and whether a plan qualifies for a cut of an estimated $3 billion in incentive payments from the Centers for Medicare & Medicaid Services in 2012.1 Ultimately, the success or failure of a plan could be determined by MSQRS.

Consider Question 21 of the overall ratings for the CAHPS health plan survey: “In the last 12 months, how often was it easy to get the care, tests, or treatment you thought you needed through your health plan?”2 The mCRPC patient who is educated and given access to treatment recommended by his trusted physician––treatment effective enough to extend his life––will rate his plan higher than the patient whose choices are restricted. Tolerability profiles and mode of administration (eg, oral or IV) are other examples of highly valued choices. In effect, with all this newfound influence on the quality of care, the patient has become a de facto decision-making member of the P&T committee. Proactive payers will prepare for this brave new world by recognizing the need for an mCRPC therapy that offers a survival benefit, is well tolerated, and affords members a mode of administration that is compatible with their lifestyle. Looking ahead to the increased role patient satisfaction will play in the delivery of healthcare, the best approach is to allow physicians to prescribe FDA-approved treatments that offer their patients what the physicians feel is the best care. Access to the best care will result in the healthiest outcome for the plan as well as the patient. ■ Disclosure Statement: Dr. Chao is a consultant to Janssen Biotech, Inc.

ZYTIGA® (abiraterone acetate) Tablets Brief Summary of Prescribing Information. INDICATIONS AND USAGE ZYTIGA in combination with prednisone is indicated for the treatment of patients with metastatic castration-resistant prostate cancer (CRPC) who have received prior chemotherapy containing docetaxel. CONTRAINDICATIONS Pregnancy: ZYTIGA may cause fetal harm when administered to a pregnant woman. ZYTIGA is contraindicated in women who are or may become pregnant. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. WARNINGS AND PRECAUTIONS Hypertension, Hypokalemia and Fluid Retention Due to Mineralocorticoid Excess: Use ZYTIGA with caution in patients with a history of cardiovascular disease. ZYTIGA may cause hypertension, hypokalemia, and fluid retention as a consequence of increased mineralocorticoid levels resulting from CYP17 inhibition [see Adverse Reactions and Clinical Pharmacology (12.1) in full Prescribing Information]. Co-administration of a corticosteroid suppresses adrenocorticotropic hormone (ACTH) drive, resulting in a reduction in the incidence and severity of these adverse reactions. Use caution when treating patients whose underlying medical conditions might be compromised by increases in blood pressure, hypokalemia or fluid retention, e.g., those with heart failure, recent myocardial infarction or ventricular arrhythmia. The safety of ZYTIGA in patients with left ventricular ejection fraction <50% or NYHA Class III or IV heart failure has not been established because these patients were excluded from the randomized clinical trial. Monitor patients for hypertension, hypokalemia, and fluid retention at least once a month. Control hypertension and correct hypokalemia before and during treatment with ZYTIGA. Adrenocortical Insufficiency: Adrenocortical insufficiency has been reported in clinical trials in patients receiving ZYTIGA in combination with prednisone, following interruption of daily steroids and/or with concurrent infection or stress. Use caution and monitor for symptoms and signs of adrenocortical insufficiency, particularly if patients are withdrawn from prednisone, have prednisone dose reductions, or experience unusual stress. Symptoms and signs of adrenocortical insufficiency may be masked by adverse reactions associated with mineralocorticoid excess seen in patients treated with ZYTIGA. If clinically indicated, perform appropriate tests to confirm the diagnosis of adrenocortical insufficiency. Increased dosage of corticosteroids may be indicated before, during and after stressful situations [see Warnings and Precautions]. Hepatotoxicity: Marked increases in liver enzymes leading to drug discontinuation or dosage modification have occurred [see Adverse Reactions]. Measure serum transaminases (ALT and AST) and bilirubin levels prior to starting treatment with ZYTIGA, every two weeks for the first three months of treatment and monthly thereafter. In patients with baseline moderate hepatic impairment receiving a reduced ZYTIGA dose of 250 mg, measure ALT, AST, and bilirubin prior to the start of treatment, every week for the first month, every two weeks for the following two months of treatment and monthly thereafter. Promptly measure serum total bilirubin, AST, and ALT if clinical symptoms or signs suggestive of hepatotoxicity develop. Elevations of AST, ALT, or bilirubin from the patient’s baseline should prompt more frequent monitoring. If at any time AST or ALT rise above five times the ULN, or the bilirubin rises above three times the ULN, interrupt ZYTIGA treatment and closely monitor liver function. Re-treatment with ZYTIGA at a reduced dose level may take place only after return of liver function tests to the patient’s baseline or to AST and ALT less than or equal to 2.5X ULN and total bilirubin less than or equal to 1.5X ULN [see Dosage and Administration (2.2) in full Prescribing Information]. The safety of ZYTIGA re-treatment of patients who develop AST or ALT greater than or equal to 20X ULN and/or bilirubin greater than or equal to 10X ULN is unknown. Food Effect: ZYTIGA must be taken on an empty stomach. No food should be consumed for at least two hours before the dose of ZYTIGA is taken and for at least one hour after the dose of ZYTIGA is taken. Abiraterone Cmax and AUC0-∞ (exposure) were increased up to 17- and 10-fold higher, respectively, when a single dose of abiraterone acetate was administered with a meal compared to a fasted state. The safety of these increased exposures when multiple doses of abiraterone acetate are taken with food has not been assessed [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) in full Prescribing Information]. ADVERSE REACTIONS The following are discussed in more detail in other sections of the labeling: Hypertension, hypokalemia, and fluid retention due to mineralocorticoid excess [see Warnings and Precautions]. Adrenocortical insufficiency [see Warnings and Precautions]. Hepatotoxicity [see Warnings and Precautions]. Food effect [see Warnings and Precautions].

ZYTIGA® (abiraterone acetate) Tablets Clinical Trial 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 clinical practice. In a placebo-controlled, multicenter phase 3 clinical trial of patients with metastatic castration-resistant prostate cancer who were using a gonadotropin-releasing hormone (GnRH) agonist or were previously treated with orchiectomy, ZYTIGA was administered at a dose of 1,000 mg daily in combination with prednisone 5 mg twice daily in the active treatment arm (N = 791). Placebo plus prednisone 5 mg twice daily was given to control patients (N = 394). The median duration of treatment with ZYTIGA was 8 months. The most common adverse drug reactions (≥5%) reported in clinical studies were joint swelling or discomfort, hypokalemia, edema, muscle discomfort, hot flush, diarrhea, urinary tract infection, cough, hypertension, arrhythmia, urinary frequency, nocturia, dyspepsia, fractures and upper respiratory tract infection. The most common adverse drug reactions that resulted in drug discontinuation were aspartate aminotransferase increased, alanine aminotransferase increased, urosepsis and cardiac failure (each in <1% of patients taking ZYTIGA). Adverse reactions and laboratory abnormalities related to mineralocorticoid effects were reported more commonly in patients treated with ZYTIGA than in patients treated with placebo: hypokalemia 28% versus 20%, hypertension 9% versus 7% and fluid retention (edema) 27% versus 18%, respectively (see Table 1). In patients treated with ZYTIGA, grades 3 to 4 hypokalemia occurred in 5% of patients and grades 3 to 4 hypertension was reported in 1% of patients [see Warnings and Precautions]. Table 1 shows adverse reactions due to ZYTIGA that occurred with either a ≥ 2% absolute increase in frequency compared to placebo, or were events of special interest (mineralocorticoid excess, cardiac adverse reactions, and liver toxicities).

Drugs that Inhibit or Induce CYP3A4 Enzymes: Based on in vitro data, ZYTIGA is a substrate of CYP3A4. The effects of strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, nefazodone, saquinavir, telithromycin, ritonavir, indinavir, nelfinavir, voriconazole) or inducers (e.g., phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital) on the pharmacokinetics of abiraterone have not been evaluated, in vivo. Avoid or use with caution, strong inhibitors and inducers of CYP3A4 during ZYTIGA treatment [see Clinical Pharmacology (12.3) in full Prescribing Information].

Includes all fractures with the exception of pathological fracture Includes terms Arrhythmia, Tachycardia, Atrial fibrillation, Supraventricular tachycardia, Atrial tachycardia, Ventricular tachycardia, Atrial flutter, Bradycardia, Atrioventricular block complete, Conduction disorder, and Bradyarrhythmia 7 Includes terms Angina pectoris, Chest pain, and Angina unstable. Myocardial infarction or ischemia occurred more commonly in the placebo arm than in the ZYTIGA arm (1.3% vs. 1.1% respectively). 8 Includes terms Cardiac failure, Cardiac failure congestive, Left ventricular dysfunction, Cardiogenic shock, Cardiomegaly, Cardiomyopathy, and Ejection fraction decreased Cardiovascular Adverse Reactions: Cardiovascular adverse reactions in the phase 3 trial are shown in Table 1. The majority of arrhythmias were grade 1 or 2. Grade 3-4 arrhythmias occurred at similar rates in the two arms. There was one death associated with arrhythmia and one patient with sudden death in the ZYTIGA arm. No patients had sudden death or arrhythmia associated with death in the placebo arm. Cardiac ischemia or myocardial infarction led to death in 2 patients in the placebo arm and 1 death in the ZYTIGA arm. Cardiac failure resulting in death occurred in 1 patient on both arms. Hepatotoxicity: Drug-associated hepatotoxicity with elevated ALT, AST, and total bilirubin has been reported in patients treated with ZYTIGA. Across all clinical trials, liver function test elevations (ALT or AST increases of > 5X ULN) were reported in 2.3% of patients who received ZYTIGA, typically during the first 3 months after starting treatment. In the phase 3 trial, patients whose baseline ALT or AST were elevated were more likely to experience liver function test elevations than those beginning with normal values. When elevations of either ALT or AST > 5X ULN, or elevations in bilirubin > 3X ULN were observed, ZYTIGA was withheld or discontinued. In two instances marked increases in liver function tests occurred [see Warnings and Precautions]. These two patients with normal baseline hepatic function, experienced ALT or AST elevations 15 to 40X ULN and bilirubin elevations 2 to 6 X ULN. Upon discontinuation of ZYTIGA, both patients had normalization of their liver function tests and one patient was re-treated with ZYTIGA without recurrence of the elevations. In clinical trials, the following patients were excluded: patients with active hepatitis, patients with baseline ALT and/or AST ≥ 2.5X ULN in the absence of liver metastases, and patients with ALT and/or AST > 5X ULN in the presence of liver metastases. Abnormal liver function tests developing in patients participating in clinical trials were managed by treatment interruption, dose modification and/or discontinuation [see Dosage and Administration (2.2) in full Prescribing Information and Warnings and Precautions]. Patients with elevations of ALT or AST > 20X ULN were not re-treated. Other Adverse Reactions: Adrenal insufficiency occurred in two patients on the abiraterone arm of the phase 3 clinical trial (< 1%). Laboratory Abnormalities of Interest: Table 2 shows laboratory values of interest from the phase 3 placebo-controlled clinical trial. Grade 3-4 low serum phosphate (7.2%) and potassium (5.3%) occurred more frequently in the ZYTIGA arm. 6

DRUG INTERACTIONS Effects of Abiraterone on Drug Metabolizing Enzymes: ZYTIGA is an inhibitor of the hepatic drug-metabolizing enzyme CYP2D6. In a CYP2D6 drug-drug interaction trial, the Cmax and AUC of dextromethorphan (CYP2D6 substrate) were increased 2.8- and 2.9-fold, respectively, when dextromethorphan was given with abiraterone acetate 1,000 mg daily and prednisone 5 mg twice daily. Avoid co-administration of abiraterone acetate with substrates of CYP2D6 with a narrow therapeutic index (e.g., thioridazine). If alternative treatments cannot be used, exercise caution and consider a dose reduction of the concomitant CYP2D6 substrate drug [see Clinical Pharmacology (12.3) in full Prescribing Information]. In vitro, ZYTIGA was shown to inhibit the hepatic drug-metabolizing enzyme CYP2C8. There are no clinical data on the use of ZYTIGA with drugs that are substrates of CYP2C8.

USE IN SPECIFIC POPULATIONS Pregnancy: Pregnancy Category X [see Contraindications]. ZYTIGA is contraindicated in women who are or may become pregnant while receiving the drug. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus and the potential risk for pregnancy loss. Women of childbearing potential should be advised to avoid becoming pregnant during treatment with ZYTIGA. Nursing Mothers: ZYTIGA is not indicated for use in women. It is not known if abiraterone acetate 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 from ZYTIGA, a decision should be made to either discontinue nursing, or discontinue the drug taking into account the importance of the drug to the mother. Pediatric Use: ZYTIGA is not indicated in children. Geriatric Use: Of the total number of patients in a phase 3 trial of ZYTIGA, 71% of patients were 65 years and over and 28% were 75 years and over. No overall differences in safety or effectiveness were observed between these elderly patients and younger patients. Patients with Hepatic Impairment: The pharmacokinetics of abiraterone were examined in subjects with baseline mild (n = 8) or moderate (n = 8) hepatic impairment (Child-Pugh Class A and B, respectively) and in 8 healthy control subjects with normal hepatic function. The systemic exposure (AUC) of abiraterone after a single oral 1,000 mg dose of ZYTIGA increased by approximately 1.1-fold and 3.6-fold in subjects with mild and moderate baseline hepatic impairment, respectively compared to subjects with normal hepatic function. No dosage adjustment is necessary for patients with baseline mild hepatic impairment. In patients with baseline moderate hepatic impairment (ChildPugh Class B), reduce the recommended dose of ZYTIGA to 250 mg once daily. If elevations in ALT or AST >5X ULN or total bilirubin >3X ULN occur in patients with baseline moderate hepatic impairment, discontinue ZYTIGA treatment [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) in full Prescribing Information]. The safety of ZYTIGA in patients with baseline severe hepatic impairment has not been studied. These patients should not receive ZYTIGA. For patients who develop hepatotoxicity during treatment, interruption of treatment and dosage adjustment may be required [see Dosage and Administration (2.2) in full Prescribing Information, Warnings and Precautions, and Clinical Pharmacology (12.3) in full Prescribing Information]. Patients with Renal Impairment: In a dedicated renal impairment trial, the mean PK parameters were comparable between healthy subjects with normal renal function (N=8) and those with end stage renal disease (ESRD) on hemodialysis (N=8) after a single oral 1,000 mg dose of ZYTIGA. No dosage adjustment is necessary for patients with renal impairment [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3) in full Prescribing Information]. OVERDOSAGE: There have been no reports of overdose of ZYTIGA during clinical studies. There is no specific antidote. In the event of an overdose, stop ZYTIGA, undertake general supportive measures, including monitoring for arrhythmias and cardiac failure and assess liver function. Storage and Handling: Store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F) [see USP controlled room temperature]. Based on its mechanism of action, ZYTIGA may harm a developing fetus. Therefore, women who are pregnant or women who may be pregnant should not handle ZYTIGA without protection, e.g., gloves [see Use in Specific Populations]. Manufactured by: Patheon Inc.

discomfort, pain under left ribs, early satiety, pruritus, night sweats and bone/muscle pain.9 To include PROs in the trial, a novel instrument had to be specifically developed. After patient interviews, advice from clinical experts and extensive input from the FDA, the modified Myelofibrosis Symptom Assessment Form, version 2.0 (modified MFSAF v2.0) was finalized as part of the Special Protocol Assessment prior to the initiation of COMFORT-I. Ultimately, Jakafi was approved by the FDA for the treatment of intermediate or high-risk MF.1,8 This became Incyte’s first approved drug and also the first oncology medicine approved with symptom data in its label since the FDA’s draft guidance on PROs was finalized in 2009.2,4

Indications and Usage Jakafi is indicated for treatment of patients with intermediate or high-risk myelofibrosis, including primary myelofibrosis, post–polycythemia vera myelofibrosis and post–essential thrombocythemia myelofibrosis. Important Safety Information • Treatment with Jakafi can cause hematologic adverse reactions, including thrombocytopenia, anemia and neutropenia, which are each dose-related effects, with the most frequent being thrombocytopenia and anemia. A complete blood count must be performed before initiating therapy with Jakafi. Complete blood counts should be monitored as clinically indicated and dosing adjusted as required • The three most frequent non-hematologic adverse reactions were bruising, dizziness and headache • Patients with platelet counts <200 × 109/L at the start of therapy are more likely to develop thrombocytopenia

during treatment. Thrombocytopenia was generally reversible and was usually managed by reducing the dose or temporarily withholding Jakafi. If clinically indicated, platelet transfusions may be administered • Patients developing anemia may require blood transfusions. Dose modifications of Jakafi for patients developing anemia may also be considered • Neutropenia (ANC <0.5 × 109/L) was generally reversible and was managed by temporarily withholding Jakafi • Patients should be assessed for the risk of developing serious bacterial, mycobacterial, fungal and viral infections. Active serious infections should have resolved before starting Jakafi. Physicians should carefully observe patients receiving Jakafi for signs and symptoms of infection (including herpes zoster) and initiate appropriate treatment promptly • A dose modification is recommended when administering Jakafi with strong CYP3A4 inhibitors or in patients with

PROVIDING proof of patient benefit MF is progressive, and spleen size and symptoms can become increasingly burdensome to patients over time.5-7 Jakafi is proven to decrease total symptom score in patients with intermediate or high-risk MF—this is an important consideration when evaluating and treating patients.9 The FDA approval included patients with intermediate-2 risk and high risk, as well as patients with intermediate-1 risk, since intermediate-1 patients may also have symptoms that require treatment. Clinical experience with Jakafi has shown that with the right process, manufacturers can successfully collaborate with regulatory agencies and academic experts to develop relevant and validated PRO instruments that can be incorporated into clinical trials.1,8 The approval of Jakafi marks a significant milestone in which validated PRO instruments can provide symptom data and demonstrate clinical benefit. The experience with Jakafi may provide a model for the future use of PROs in marketing applications.8

renal or hepatic impairment [see Dosage and Administration]. Patients should be closely monitored and the dose titrated based on safety and efficacy • There are no adequate and well-controlled studies of Jakafi in pregnant women. Use of Jakafi during pregnancy is not recommended and should only be used if the potential benefit justifies the potential risk to the fetus • Women taking Jakafi should not breast-feed.

a As studied in COMFORT-I, a randomized, double-blind, placebo-controlled phase III

study with 309 total patients (United States, Canada, Australia). The primary endpoint was the proportion of subjects achieving a ≥35% reduction in spleen volume from baseline to Week 24 as measured by MRI or computed tomography (CT). A secondary endpoint was the proportion of subjects with a ≥50% reduction in TSS from baseline to Week 24 as measured by the daily patient diary, the modified MFSAF v2.0.9,10 b Symptom scores were captured by a daily patient diary recorded for 25 weeks. TSS encompasses debilitating symptoms of MF: abdominal discomfort, pain under left ribs, early satiety, pruritus, night sweats and bone/muscle pain. Symptom scores ranged from 0 to 10 with 0 representing symptoms “absent” and 10 representing “worst imaginable” symptoms. These scores were added to create the daily total score, which has a maximum of 60. At baseline, mean TSS was 18.0 in the Jakafi group and 16.5 in the placebo group.9,10

Tradjenta (linagliptin) Tablets: A 速

Single-Dose Treatment Option for Adults with Type 2 Diabetes

T

he various classes of oral antihyperglycemic agents differ in terms of their mechanisms of action. Among the traditional agents, metformin and the thiazolidinediones enhance insulin sensitivity, the sulfonylureas and glinides enhance insulin secretion, and the alpha-glucosidase inhibitors inhibit intestinal carbohydrate absorption.1 Dipeptidyl peptidase (DPP)-4 inhibitors, a relatively recent addition to the armamentarium of oral antihyperglycemic drugs, act by potentiating the activity of the incretins glucagon-like peptide (GLP)-1 and glucose-dependent insulinotropic polypeptide (GIP) and enhancing glucose-dependent insulin secretion.1 Tradjenta速 (linagliptin) tablets, a DPP-4 inhibitor indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes, was approved by the US Food and Drug Administration in May 2011.2,3 TRADJENTA has not been studied in combination with insulin and should not be used in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis.3 TRADJENTA is available in a single 5-mg dose.3 Because linagliptin is primarily excreted via the bile and gut, no dose adjustment is recommended in patients with renal insufficiency.3 Likewise, the administration of linagliptin in patients with hepatic impairment did not result in reductions in DPP-4 inhibition; therefore, dose adjustment is not necessary in this patient population.3 Linagliptin is not a clinically relevant substrate or inhibitor of cytochrome P450 or P-glycoprotein. As a result, TRADJENTA can be coadministered with other drugs frequently prescribed to patients with type 2 diabetes, such as metformin, glyburide, simvastatin, warfarin, and digoxin.3,4 When TRADJENTA is used in combination with an insulin secretagogue such as a sulfonylurea, a lower dose of the insulin secretagogue may be required to reduce the risk of hypoglycemia.3

Clinical Pharmacology Linagliptin binds selectively to DPP-4, thereby increasing the concentrations of the active incretin hor-

mones GLP-1 and glucose-dependent insulinotropic peptide (GIP).5,6 These hormones are secreted at low basal levels in the fasting state, with circulating levels increasing rapidly after food ingestion.5 In the postprandial state, GLP-1 and GIP act on pancreatic beta-cells to stimulate glucose-dependent insulin secretion. GLP-1, but not GIP, inhibits gastric emptying, glucagon secretion, and food intake.3,7 Through these physiologic mechanisms, linagliptin increases insulin secretion and lowers glucagon secretion in a glucosedependent manner, resulting in improved regulation of glucose homeostasis in patients with type 2 diabetes.3 The pharmacokinetics of linagliptin is similar in healthy persons and in patients with type 2 diabetes.3 After oral administration of a single 5-mg dose to healthy persons, peak plasma concentrations of linagliptin are reached at approximately 1.5 hours postdose.3 Plasma concentrations of linagliptin decline in at least a biphasic manner with a terminal half-life of more than 100 hours; however, the prolonged elimination phase does not contribute to the accumulation of the drug.3 The effective half-life for accumulation of linagliptin is approximately 12 hours. After once-daily dosing, steady-state plasma concentrations of linagliptin 5 mg are reached by the third dose.3 The mean apparent volume of distribution at steady state (1110 L) indicates that linagliptin extensively distributes to the tissues.3 Plasma protein binding of linagliptin is concentration-dependent, reflecting saturation of binding to DPP-4 with increasing concentration of linagliptin. When DPP-4 is fully saturated, 70% to 80% of linagliptin remains bound to plasma proteins and 20% to 30% is unbound in plasma. Plasma binding is not altered in patients with renal or hepatic impairment.3 The absolute bioavailability of linagliptin is approximately 30%, and TRADJENTA may be administered with or without food.3

Clinical Studies TRADJENTA has been studied as monotherapy, as add-on combination with metformin, as add-on combination with metformin and sulfonylureas, and in initial

Approximately 3800 patients with type 2 diabetes were enrolled in 8 randomized, placebo-controlled, safety and efficacy studies that evaluated the effects of linagliptin on glycemic control.3 In clinical studies, patients receiving Tradjenta® (linagliptin) tablets achieved clinically meaningful A1C reductions with oral monotherapy, dual therapy, and triple therapy at 24 weeks.4,8-10 With TRADJENTA, patients across a broad range of ages achieved statistically significant A1C reductions.11 In a prespecified subgroup analysis using pooled data from 4 pivotal phase 3 studies, A1C reduction for adult patients with type 2 diabetes was evaluated in 4 different age groups. Results showed significant A1C reductions

in each age group at 24 weeks. The placebo-adjusted mean change in A1C from baseline was –0.6% for patients aged ≤50 years (P <0.0001), –0.6% for patients aged 51 to 64 years (P <0.0001), –0.6% for patients aged 65 to 74 years (P <0.0001), and –0.8% for patients aged ≥75 years (P = 0.0002).11 The 2 older age groups were combined in the Figure for ease of readability. Clinical experience with TRADJENTA has not identified differences in response between the elderly and younger patients; however, greater sensitivity of some older individuals cannot be ruled out.

controlled study, treatment-naïve and treatment-experienced adult patients with type 2 diabetes were randomized to Tradjenta® (linagliptin) tablets 5 mg daily or to placebo for 24 weeks.3,8 The primary endpoint was the change in A1C levels at 24 weeks, and the secondary endpoints included the changes in fasting plasma glucose (FPG) and 2-hour postprandial glucose (PPG) levels.8 Treatment with TRADJENTA provided statistically significant improvements in A1C levels, FPG, and 2-hour PPG compared with placebo. At study week 24, the adjusted mean change in A1C from baseline was –0.4% among patients given TRADJENTA and 0.3% among those receiving placebo, representing a placebo-adjusted improvement in mean A1C of –0.7% (P <0.0001) (Table 1).3,8 Patients also achieved significant reductions in PPG and FPG. After 24 weeks, treatment with TRADJENTA resulted in a placebo-adjusted mean change in 2-hour PPG of –58.4 mg/dL (P <0.0001) and a placebo-adjusted mean change in FPG of –23.3 mg/dL (P <0.0001).3,8 In this study, 20.9% of patients in the placebo group required use of rescue therapy versus 10.2% of patients in the TRADJENTA group.3

Combination Therapy with TRADJENTA TRADJENTA has demonstrated clinically meaningful A1C reductions as an add-on therapy to metformin and as an add-on therapy to metformin and a sulfonylurea, and in initial combination therapy with pioglitazone, respectively.4,9,10 Add-on Combination Therapy with Metformin In a randomized, double-blind, placebo-controlled, parallel-group study of TRADJENTA in adult patients with type 2 diabetes and insufficient glycemic control despite metformin therapy, patients were randomized to TRADJENTA 5 mg daily or to placebo in combination with metformin ≥1500 mg daily for 24 weeks.3,9 The primary endpoint was the change from baseline in A1C at 24 weeks, and the secondary endpoints included changes from baseline in FPG and 2-hour PPG.9 In this study, treatment with TRADJENTA provided a significant placebo-adjusted improvement in mean A1C of –0.6% after 24 weeks (P <0.0001).3,9 With regard to secondary endpoints, after 24 weeks of treatment, patients receiving TRADJENTA showed a placebo-adjusted mean change in 2-hour PPG of –67.1 mg/dL from baseline (P <0.0001) and a placebo-adjusted mean change in FPG of –21.1 mg/dL from baseline (P <0.0001).3,9 In the study, 18.9% of patients in the placebo group required use of rescue therapy versus 7.8% of patients in the TRADJENTA group.3

Add-on Combination Therapy with Metformin and a Sulfonylurea In a randomized, double-blind, placebo-controlled, parallel-group study, triple therapy with TRADJENTA was compared with triple therapy with placebo in adult patients with type 2 diabetes and insufficient glycemic control despite treatment with metformin in combination with a sulfonylurea.3,10 Patients were randomized to TRADJENTA 5 mg daily or placebo as an add-on to existing metformin plus sulfonylurea therapy.3,10 The primary endpoint was change from baseline A1C at 24 weeks.10 When added to metformin and a sulfonylurea, treatment with TRADJENTA provided a significant, placebo-adjusted mean A1C improvement of –0.6% at 24 weeks (P <0.0001).3,10 A total of 13% of patients in the placebo group required use of rescue therapy versus 5.4% of patients in the TRADJENTA group.3 Add-on Combination Therapy with Pioglitazone In a third study evaluating the safety and efficacy of TRADJENTA as initial combination therapy in type 2 diabetes, patients were randomized to receive either TRADJENTA 5 mg or placebo, both in addition to pioglitazone 30 mg once daily for 24 weeks.3,4 The primary endpoint was the change from baseline in A1C at 24 weeks, and secondary endpoints included the change in baseline FPG.4 At study week 24, treatment with TRADJENTA plus pioglitazone showed a statistically significant placebo-adjusted improvement (P <0.0001) in mean A1C of –0.5% compared with placebo plus pioglitazone.3,4 TRADJENTA also provided a statistically significant improvement in FPG levels, providing a statistically significant placebo-adjusted improvement (P <0.0001) in mean FPG of –14.2 mg/dL at week 24 following treatment with TRADJENTA plus pioglitazone.3,4 Rescue therapy was used in 7.9% of patients who received TRADJENTA 5 mg/pioglitazone 30 mg and 14.1% of patients who received placebo/pioglitazone 30 mg.3 Active-Control Study versus Glimepiride in Combination with Metformin The goal of a 104-week, double-blind, glimepiridecontrolled noninferiority study was to evaluate the comparative efficacy and safety of TRADJENTA versus glimepiride.3 Adult patients with type 2 diabetes and insufficient glycemic control despite metformin therapy were randomized to add-on therapy with TRADJENTA 5 mg daily or to glimepiride. Patients receiving glimepiride were given an initial dose of 1 mg daily that was titrated to a maximum dose of 4 mg daily, as needed.3 The

Analysis

Key efficacy results

Phase 3, randomized, double-blind, active-control, parallel group

Adults aged 18-80 yrs with type 2 diabetes and insufficient glycemic control, despite metformin therapy

Glimepiride (N = 761) TRADJENTA (N = 766)

Primary: Change in A1C at 52 weeks Secondary: Change in body weight from baseline to week 52 Occurrence of hypoglycemic events up to 52 weeks

Primary endpoint: Analysis of covariance (ANCOVA) with baseline A1C as covariate Secondary endpoints: Confirmatory testing of treatment superiority with linagliptin vs glimepiride

• Noninferiority of TRADJENTA to glimepiride in A1C levels (P = 0.0007, 1-sided for noninferiority) • Significant lower incidence of hypoglycemia with TRADJENTA vs glimepiride (P < 0.0001) • Significant mean decrease in baseline body weight with TRADJENTA vs glimepiride (P < 0.0001)

a

Model includes continuous baseline A1C and treatment. Defined as all randomized patients treated with at least 1 dose of study drug who had a baseline A1C value and at least 1 on-treatment A1C value. The full analysis set is the basis for the ITT analysis. FPG indicates fasting plasma glucose; ITT, intention to treat; PPG, postprandial glucose.

b

average daily dose of glimepiride was 3 mg. The primary endpoint in this interim analysis was the change from baseline in A1C after 52 weeks of treatment.11 Patients in the intent-to-treat population (last observation carried forward) who received Tradjenta® (linagliptin) tablets achieved an adjusted mean A1C reduction of 0.4% (N = 766) from baseline at 52 weeks versus a 0.6% reduction with glimepiride (N = 761), showing noninferiority of TRADJENTA to glimepiride (P = 0.0007, 1-sided for noninferiority).3,11 Furthermore, statistically similar proportions of patients receiving TRADJENTA (39.6%) or glimepiride (44.7%) achieved the A1C goal of <7.0%.11 Although the 2 drugs demonstrated similar efficacy, the incidence of hypoglycemia was nearly 6 times greater for patients treated with glimepiride (31.8%) versus TRADJENTA (5.4%).3 Patients treated with TRADJENTA showed a significant mean decrease from baseline body weight compared with a significant weight gain in patients receiving glimepiride (–1.1 kg vs +1.4 kg, respectively; P <0.0001).3

Safety The safety of linagliptin has been evaluated in more than 4000 patients with type 2 diabetes in clinical trials.3 In placebo-controlled clinical studies, adverse reactions reported in ≥5% of patients treated with TRADJENTA and more frequently than in patients treated with placebo included nasopharyngitis.3 In placebo‐controlled studies, 195 (7.6%) of the 2566 patients who received TRADJENTA 5 mg reported hypoglycemia compared with 49 (4.1%) of the 1183 patients who received placebo. The incidence of hypoglycemia was similar to that with placebo when TRADJENTA was administered as monotherapy or in combination with metformin or pioglitazone.3 Hypoglycemia was more frequently reported in patients who received the combination of TRADJENTA and sulfonylurea compared with those who received the combination of placebo and sulfonylurea.3 When TRADJENTA was administered in combination with metformin and a sulfonylurea, 181 of 791 (22.9%) patients reported hypoglycemia compared with 39 of 263 (14.8%) patients receiving placebo in

a In the active-control, noninfertioty, 104-week study of TRADJENTA versus glimepiride, the most frequently reported adverse events in both groups were infections and infestations (39.1% vs 41.1%, respectively); musculoskeletal and connective tissue disorders (25.2% vs 22.3%, respectively); and gastrointestinal disorders (21.6% vs 22.7%, respectively).11 a Pooled data from 7 studies. b Pooled data from 2 studies. c Includes reports of hypertriglyceridemia (N = 2; 1.2%) and blood triglycerides increased (N = 2; 1.2%).

combination with metformin and a sulfonylurea.3 In the clinical trial program, the incidence of pancreatitis was 1 case per 538 person-years with TRADJENTA versus 0 in 433 person-years with a comparator. Three additional cases of pancreatitis were reported after the last administered dose of TRADJENTA.3 Adverse reactions reported in ≥2% of patients who received Tradjenta® (linagliptin) tablets and at least 2 times greater than with placebo are shown in Table 2. The safety and effectiveness of TRADJENTA in patients aged <18 years have not been established.3

Conclusion TRADJENTA 5 mg is the only single-dosage DPP-4 inhibitor available for adult patients with type 2 diabetes.3,12,13 When administered as monotherapy, dual therapy, or triple therapy in adults with inadequate glycemic control, TRADJENTA produced statistically significant A1C percent reductions at 24 weeks.4,8-10 Furthermore, a prespecified subgroup analysis demonstrated significant A1C percent reductions across a broad range of age groups.11 TRADJENTA also showed significant reduc-

tions in FPG and 2-hour PPG when administered as monotherapy or as add-on combination therapy with metformin.3,8,9 Compared with glimepiride in combination with metformin, TRADJENTA and glimepiride demonstrated similar A1C reductions from baseline after 52 weeks; however, patients experienced a lower incidence of hypoglycemia and significant mean decrease from baseline body weight with TRADJENTA compared with glimepiride.3 TRADJENTA has a demonstrated safety and tolerability profile based on safety data from more than 4000 patients.3 It is primarily excreted via the bile and gut.3,12,13 No dose adjustment is recommended for patients with renal impairment or with hepatic impairment.3,12,13 ■

Indication and Important Limitations of Use TRADJENTA is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. TRADJENTA should not be used in patients with type 1 diabetes or for the treatment of diabetic ketoacidosis. TRADJENTA has not been studied in combination with insulin.

Important Safety Information CONTRAINDICATIONS TRADJENTA is contraindicated in patients with a history of hypersensitivity reaction to linagliptin, such as urticaria, angioedema or bronchial hyperreactivity. WARNINGS AND PRECAUTIONS Use with Medications Known to Cause Hypoglycemia Insulin secretagogues are known to cause hypoglycemia. The use of TRADJENTA in combination with an insulin secretagogue (e.g., sulfonylurea) was associated with a higher rate of hypoglycemia compared with placebo in a clinical trial. Therefore, a lower dose of the insulin secretagogue may be required to reduce the risk of hypoglycemia when used in combination with TRADJENTA. Macrovascular Outcomes There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with TRADJENTA or any other antidiabetic drug. ADVERSE REACTIONS Adverse reactions reported in â&#x2030;Ľ5% of patients treated with TRADJENTA and more commonly than in patients treated with placebo included nasopharyngitis. Hypoglycemia was more commonly reported in patients treated with the combination of TRADJENTA and sulfonylurea compared with those treated with the combination of placebo and sulfonylurea. When linagliptin was administered in combination with metformin and a sulfonylurea, 181 of 791 (22.9%) patients reported hypoglycemia compared with 39 of 263 (14.8%) patients administered placebo in combination with metformin and a sulfonylurea. In the clinical trial program, pancreatitis was reported in 8 of 4687 patients (4311 patient-years of exposure [1 per 538 personyears]) while being treated with TRADJENTA compared with 0 of 1183 patients (433 patient-years of exposure) treated with placebo. Three additional cases of pancreatitis were reported following the last administered dose of linagliptin. DRUG INTERACTIONS The efficacy of TRADJENTA may be reduced when administered in combination with a strong P-glycoprotein or CYP3A4 inducer (e.g., rifampin). Therefore, use of alternative treatments to TRADJENTA is strongly recommended. USE IN SPECIFIC POPULATIONS There are no adequate and well-controlled studies in pregnant women. Therefore, TRADJENTA should be used during pregnancy only if clearly needed. It is not known whether linagliptin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when TRADJENTA is administered to a nursing woman. The safety and effectiveness of TRADJENTA in patients below the age of 18 have not been established. TJ PROF ISI FEB162012

AMERICAN HEALTH & DRUG BENEFITS

June 2012


The 2012 Pharmaceutical Pipeline (As of June 8, 2012) By Karen Cooksey and Dalia Buffery

L

ast year, the US Food and Drug Administration (FDA) approved approximately 32 new drugs (35 in fiscal year 2011), depending on which drugs are counted; this included 10 orphan drugs, a trend that is expected to continue, as well as many drugs with new mechanisms of action or first-ever medications for certain conditions.1 Although the total number of FDA approvals for new drugs will likely be smaller in 2012 than in 2011, other recent trends in the pharmaceutical pipeline will continue and perhaps intensify in 2012, such as a growing surge in cancer drugs and orphan drugs in the pipeline, the steady focus by pharmaceutical companies on specialty drugs, the increasing number of companion testing with targeted therapies, and the transition from injections to oral administration of biologic agents for a variety of disease states, including cancer. The focus on specialty drugs has gradually been transforming drug development, as can be seen in the number of traditional versus specialty drugs approved by the FDA. In 2008, the FDA approved 16 small-molecule traditional drugs and 8 specialty drugs; in 2011, that ratio was reversed, with a total of 12 traditional and 18 specialty drugs approved.2 So far in 2012, the FDA has signaled it would continue to expedite its review process by applying the priority review process when the evidence is deemed appropriate. By mid-June, 14 new brand-name drugs were approved by the FDA (Table 1), and many important drugs are expected to be approved throughout the year, although it is generally accepted that the era of the “blockbuster drug” is over. Cancer drugs continue to lead the way in 2012 in the pharmaceutical pipeline. Early in June, the FDA indicated it expected another 20 cancer drug applications to be submitted this year for approval.3 Since then, 1 new cancer drug has been approved (Table 1), and several New Drug Applications (NDAs) have been accepted. One trend that may be reversed in 2012 is the number of new drugs that are approved with the Risk Evaluation and Mitigation Strategy (REMS) program. Compared with 2011, the number of new drugs, including biologics, approved with the REMS requirement has so far decreased considerably in 2012. Among the significant drugs that are likely to come up for FDA approval this year are 4 new drugs for the treatment of multiple sclerosis, including new oral disease-modifying drugs; as well as the 2 obesity drugs,

lorcaserin hydrochloride and phentermine/topiramate. Currently, the disease states with the highest number of drugs in the pipeline are: • Cancer, >320 drugs • Central nervous system (CNS) disorders, >150 drugs • Diabetes, >80 drugs • Cardiovascular disease (CVD) and infectious diseases, >70 drugs each • Respiratory diseases, >60 drugs • Rheumatic diseases, >50 drugs.

Promising Drugs in Late-Stage Development Table 2 lists some of the major drugs expected to come up for approval in 2012 or in early 2013. Cancer By June 8, 2012, 5 new cancer drugs have been approved by the FDA. The approval of the most recent cancer drug, Perjeta (pertuzumab), which is indicated for HER2-positive metastatic breast cancer, was expedited by the FDA under the priority review process. Among the 20 or so cancer drugs expected to be considered by the FDA in 2012,1 perhaps the 3 to watch for include carfilzomib, a proteasome inhibitor for the treatment of refractory or relapsed multiple myeloma, with a PDUFA (Prescription Drug User Fee Act) date of July 27, 2012; pomalidomide, a new immunomodulating drug, to be combined with low-dose dexamethasone, also for the treatment of patients with relapsed or refractory multiple myeloma; and enzalutamide (MDV3100), an androgen receptor antagonist for chemotherapyrefractory prostate cancer, with an NDA submitted this year; if approved, it would be competing with Zytiga (abiraterone acetate) for the treatment of metastatic castration-resistant prostate cancer in patients who have received previous docetaxel chemotherapy. (Enzalutamide is also being studied in patients who have not received chemotherapy.) CNS Disorders The CNS drug closest to approval is most likely Levadex (dihydroergotamine [DHE]), an orally inhaled agent for the acute treatment of migraine. Levadex is a novel formulation of DHE, which is currently available in other formulations for the treatment of migraine. The FDA issued a complete response letter on March 26, 2012, identifying nonclinical issues that will need to be

Diabetes In 2012, only 2 new drugs were expected to be approved

for diabetes. The first is alogliptin, an orally administered dipeptidyl peptidase (DPP)-4 inhibitor, that is being investigated for use as an adjunct to diet and exercise for the treatment of type 2 diabetes. The FDA issued a complete response letter on April 25, 2012, but the company intends to continue working with the FDA on this approval. The second antidiabetes drug is degludec, an ultralong-acting basal insulin, with a July 29, 2012, PDUFA date; if approved, it would be competing with Lantus (insulin glargine) and Levemir (insulin detemir) in this growing marketplace of patients with diabetes.

Cardiovascular Diseases Of the many drugs in the pipeline being developed for CVD conditions, only a few are scheduled for FDA review in 2012. Several new NDAs have been filed or will be filed later in the year, with 1 or 2 drugs expected to be approved in 2012. A July PDUFA date is set for AMR101, an oral agent for patients with very high triglyceride levels (>500 mg/dL). Infectious Diseases In 2012, the main activity in drug development will involve HIV drugs, with 2 drugs expected to be approved including QUAD (elvitegravir, cobicistat, emtricitabine, tenofovir), a once-daily, 4-drug oral combination that could simplify the antiretroviral treatment in this patient population, and dolutegravir, a new-generation integrase inhibitor that is the first competitor to the sole-approved drug in its class, Isentress (raltegravir). The anticipated once-daily dosing of dolutegravir will greatly help the marketing of the drug. NDA filing is expected by end of the year. Respiratory Diseases The front-runner among drugs in the pipeline for respiratory diseases is Eklira (aclidinium), a twice-daily, long-acting muscarinic antagonist oral inhaler for maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease. Two inhalers containing this agent are in development, one with aclidinium monotherapy and the other with a combination of aclidinium with formoterol. Rheumatic Diseases Several exciting developments are taking place in the various rheumatic diseases, with an increasing number of biologics entering the pipeline for these conditions. The majority of these agents are expected to reach FDA approval in 2013 or 2014. Arcalyst (rilonacept), the much anticipated subcutaneous (SC) biologic agent investigated for an expanded indication for the treatment of gout, is scheduled for

THE 2012 PHARMACEUTICAL PIPELINE

FDA review in July (PDUFA date, July 30, 2012); however, an FDA advisory panel voted 11 to 0 against this gout indication on May 4, 2012.4 The manufacturer intends to pursue this expanded indication nevertheless. The second SC biologic drug for gout in the pipeline is Ilaris, which is in an earlier stage of development, with FDA approval expected in 2014. Tofacitinib, a novel oral Janus kinase (JAK) inhibitor, is being investigated as a targeted immunomodulator and disease-modifying antirheumatic drug (DMARD) for rheumatoid arthritis (RA, as well as for psoriasis). Unlike more recent FDA-approved therapies for RA, which are directed at extracellular targets such as proinflammatory cytokines, tofacitinib targets multiple intracellular immune response pathways. The safety profile is problematic. If approved, tofacitinib would be the first new oral DMARD approved by the FDA for RA in more than 10 years, and the first in the new class of antirheumatic JAK inhibitors approved for RA. In addition, 2 biologics being developed for the treatment of lupus are Lupuzor and LymphoCide, but these too are expected to come up for approval in 2014. Similarly, the biologic drug for psoriatic arthritis to watch, Apremilast, is expected to come up for approval in 2013.

Substantial Activity in 2012 So far, 2012 continues the trends of new-generation

drug therapies for a variety of disease categories, increasing oral formulations of biologics, growing competition in the cancer arena, and the FDA’s intent on using priority review when warranted. However, the agency has also delivered some surprises for drugs that were widely expected to be approved but instead were issued a complete response letter requesting additional data or new information that had not been anticipated by the manufacturers and the entire pharmaceutical industry. Still, 2012 has all the signs of prolific activity in the drug pipeline, despite the apparent end of the blockbuster era. And with these trends, new issues to be confronted by providers and payers will likely include the problem of medication adherence and potentially increasing adverse events, as more drugs are being taken orally by the patient instead of being administered by the clinic or the provider. ■
