MANAGED CARE NEWSSTAND Biden-Harris Administration Announces Actions to Address Youth Mental Health Crisis In late July, the Biden-Harris administration announced two new actions to strengthen school-based mental health services and address the youth mental health crisis: •

Awarding the first of nearly $300 million that the president secured through the FY2022 bipartisan omnibus agreement to expand access to mental health services in schools.

•

Encouraging governors to invest more in school-based mental health services.

In a letter sent to governors across the country, the departments of Education and Health and Human Services highlight federal resources available to states and schools to invest in mental health services for students.

These actions build upon earlier investments and announcements designed to expand access to mental health services for youth.

CMS Releases Guidance on Mental Health In August, several new resources and guidance documents were released by the Centers for Medicaid and Medicare Services (CMS) on mental health and children’s mental health. In particular, the CMS Informational Bulletin described leveraging Medicaid and the Children’s Health Insurance Program (CHIP) to deliver

on PHE flexibilities that have been largely successful and will remain in place postPHE end, as well as flexibilities that will no longer be necessary at that time. Of note, CMS lauds the value of telehealth services to the health and well-being of Americans yet maintains that expansion of telehealth use, including matters related to Medicare payment of telehealth services is an example of required congressional change.

behavioral health services for children and youth, and guidance on payment for Medicaid school-based services.

CMS Releases Informational Bulletin on Beneficiary Protections and Medicaid Drug Coverage The Center for Medicaid and CHIP Services (CMCS) released a CMCS Informational Bulletin concerning beneficiary protections and Medicaid drug coverage, particularly under Value-Based Purchasing (VBP) arrangements. This bulletin reminds states and stakeholders of the existing federal beneficiary protections in statute and regulation that must be followed when providing Medicaid pharmacy benefits, especially when states enter into novel payment arrangements with drug manufacturers, such as VBP arrangements.

CMS Releases Information on Expiration of PHE-Related Flexibilities In September, CMS released information to help prepare providers and health plans for the expiration of certain regulatory flexibilities put in place during the COVID-19 public health emergency (PHE). During the pandemic, CMS has used a combination of methods, including expanded Section 1135 emergency authority waivers, new guidance, regulatory change, and enforcement discretion to promote rapid healthcare industry stakeholder treatment and response capabilities. CMS published the following materials to inform stakeholders on the eventual termination of several flexibilities at the end of the PHE, including Medicare telehealth flexibilities (which expire 151 days after the end of the PHE): •

Creating a Roadmap for the End of the COVID-19 Public Health Emergency: Outlines the position of CMS leadership

•

Fact sheets for providers and plans on COVID-19 PHE waivers and flexibilities: Describes in detail both current flexibilities and policies as well as the impact to the flexibility or policy when the PHE concludes. Specific fact sheets include information on the impact of the PHE end of Medicare payment rates for COVID-19 vaccines and treatment, prior authorization waivers, and other flexibilities relating to the operation of Medicare Advantage and Part D plans.

•

Healthcare System Resiliency: A fact sheet on CMS strategic actions to plan for the end of the PHE and improve aspects of the U.S. healthcare system to promote long-term preparedness.

CMS notes that it is evaluating PHE blanket waivers and flexibilities in three concurrent phases, including assessing the need for continuing certain waivers post-PHE, assessing which flexibilities would be most useful in a future PHE, and collaborating with federal partners and industry stakeholders to advance equitable, high-quality, value-based care to ensure the system is adequately prepared for future emergencies.

CMS Releases Proposed Rule Streamlining Medicaid and CHIP Eligibility and Enrollment CMS recently released a notice of proposed

The Biden-Harris administration announced two new actions to strengthen schoolbased mental health services and address the youth mental health crisis. rule-making (NPRM) that would overhaul eligibility and enrollment processes for Medicaid, CHIP, and Basic Health Programs (BHPs).

Provisions of the proposed rule would standardize state eligibility and enrollment policies, such as limiting renewals to once every 12 months, allowing applicants 30 days to respond to information requests, requiring prepopulated renewal forms, and establishing consistent renewal processes across states. CMS also proposes process improvements that would increase enrollment and retention for people aged 65 and older or for individuals who receive coverage based on blindness or a disability.

For CHIP, the proposed rule would allow people to remain enrolled or re-enroll without a lockout period for failure to pay premiums, remove the option for waiting periods, and prohibit lifetime and annual benefit limits. The NPRM also proposes national standards for recordkeeping,

including eligibility information and documentation, retention requirements, application and renewal processing timelines, and requirements to maintain information in electronic data formats.

CMS Releases RFI on Medicare Advantage Program In July, CMS released a request for information (RFI) on the Medicare Advantage program. The RFI specifically seeks information on the following topics: • • • •

Advance Health Equity.

Drive Innovation to Promote PersonCentered Care.

Support Affordability and Sustainability.

Engage Partners.

HHS Issues New Proposed Antidiscrimination Regulation The Biden administration has proposed significant changes to federal antidiscrimination rules that apply to entities receiving federal healthcare funds, including payments under Medicare and Medicaid. The proposed changes broaden the definition of protections included in the provision.

House Passes Telehealth Legislation In July, the U.S. House of Representatives overwhelmingly passed legislation that would extend many current flexibilities under the Medicare program around payment for telehealth through the end of 2024. The bill would allow Medicare and federally qualified health centers — including rural health clinics — to continue covering telehealth visits from patients’ homes, as well as audio-only telehealth under Medicare. The measure would also extend a waiver permitting mental health

patients to avoid having to go to in-person visits. The bill now moves to the Senate, where it appears to have the needed votes for passage, but it faces an uncertain future as a result of several factors including the packed legislative calendar.

President Biden Signs Inflation Reduction Act The U.S. Senate and House of Representatives passed the Inflation Reduction Act (IRA) of 2022 that includes prescription drug reform, insulin price caps in Medicare, and climate and tax changes, along with a three-year extension of the American Rescue Plan Act (ARPA), which includes enhanced advanced premium tax credits (APTCs). Biden signed the bill into law in August. This new law contains several impactful provisions including the following: Rebate rule moratorium: Extends the statuary moratorium on the Centers for Medicare and Medicaid Services (CMS) regulation that would eliminate the AntiKickback Statute’s safe-harbor for Part D prescription drug rebates from January 2027 through January 2032.

HHS Drug Negotiation: Allows the federal government to negotiate drug prices with manufacturers with negotiated prices going into effect for a specific number of Part D and B drugs every year until 2026.

Part D Benefit Redesign: Eliminates the Medicare Part D coverage gap phase effective 2025, imposes an annual outof-pocket cap on beneficiary cost-sharing for prescription drugs at $2,000, changes plan liability.

Part D Insulin: Caps out-of-pocket costs at $35 a month for insulin co-pays in Part D, effective 2023.

Rheumatoid Arthritis: Biosimilar Update and Management Pending adalimumab biosimilar launches show promise that lowered costs for RA treatment are on the horizon.

Rheumatoid arthritis (RA) is a chronic, inflammatory disease that affects about 1.5 million people in the U.S.1, 2 RA is an autoimmune disease, meaning it causes the immune system to attack healthy joint tissues. It is estimated that women are two to three times more likely than men to develop RA, suggesting that hormones may play a role in this disorder.1, 2 In the U.S., the lifetime risk of RA is 3.6% for women and 1.7% for men. Symptoms generally begin to present between the ages of 30 to 60 in women and later in life for men.1, 2 While no cause is known, it is believed that a combination of factors lead to the development of the condition.

Luke Merkel, Pharm.D., MBA Director of Pharmacy Services Avera Health

RA typically occurs in a symmetrical pattern, with joints affected bilaterally.1 Joints in the wrist, hands, and feet are most prone to RA, although the spine, knees, and jaw may also be impacted.1 Symptoms of RA typically include joint pain at rest and when moving; tenderness, swelling, and warmth of the joint; joint stiffness that lasts longer than 30 minutes, typically after waking in the morning or after resting for a long period of time; fatigue; occasional low-grade fever; and loss of appetite.1 In some cases, symptoms may start as mild or moderate inflammation that, if left untreated, can worsen and lead to more joints being affected. Symptoms may worsen during “flares” due to a trigger such as stress, increased activity, or noncompliance with medication or treatment.1 Further potential complications for patients with RA include rheumatoid nodules; anemia; neck pain; and dry eyes and mouth.1 In rare cases, patients with RA may develop vasculitis, pleurisy, or pericarditis.1 Rheumatologists typically diagnose RA based on a combination of factors: a physical exam, review of medical history, blood tests, and imaging tests.3 Blood tests will often examine erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), and antibodies to cyclic citrullinated

4 | Magellan Rx Report | Fall 2022

peptides (CCP).3 Imaging tests to assess the joints include X-rays, ultrasounds, and MRI scans. Diagnostic criteria for RA generally include inflammatory arthritis in two or more large joints or in smaller joints, positive biomarker tests for RF or CCP antibodies, elevated levels of CRP or an elevated ESR, and symptoms that have lasted more than six weeks. Timely diagnosis and initiation of treatment is crucial to proper disease management.3

A number of factors play into how biosimilars will impact prescribing and management decisions, Treatment Landscape including clinical data Successful treatment for RA will decrease inflammation and pain supporting safety and efficacy as well as slowing or stopping further joint damage. Available treatments for RA include anti-inflammatory medications, as well as interchangeability corticosteroids, disease-modifying anti-rheumatic drugs (DMARDs), biologic response modifiers (BRMs), and janus kinase designations.

(JAK) inhibitors.1 Studies suggest that early treatment with a combination of medications (as opposed to monotherapy) may be more effective in decreasing or preventing joint damage.1

Adalimumab Biosimilar Launch and Payer Impact

Typically, if a patient does not respond well to DMARDs, providers may utilize biologic response modifiers, or biologics, which target molecules that cause inflammation. Some biologics indicated and used for RA include etanercept (Enbrel®), infliximab (Remicade®), adalimumab (Humira®), and rituximab (Rituxan®).

Starting in early 2023, biosimilar versions of adalimumab are anticipated to launch in the U.S. market, which is likely to impact the treatment landscape for RA as well as other indications of the drug.4 Thus far, the FDA has approved seven biosimilars for adalimumab. A number of factors play into how biosimilars will impact prescribing

RHEUMATOID ARTHRITIS | Continued

The availability of biosimilars in the RA space has had an impact on prices, and the pending launch of adalimumab biosimilars shows some promise that further lowered costs for RA treatment are on the horizon. and management decisions, including clinical data supporting safety and efficacy as well as interchangeability designations.4 Providers treating patients with RA are already familiar with biosimilars, as infliximab and rituximab biosimilars have been available for some time; this experience will impact providers’ comfort level in switching or starting patients on adalimumab biosimilars once available.5

Rheumatologists may have a higher degree of confidence in switching patients who responded well to the reference product to a biosimilar designated as interchangeable.4 This designation may also increase utilization of respective biosimilars as they launch.

While biosimilars with interchangeable status can be dispensed in place of an originator brand without physician approval, some states have placed restrictions; in many states, providers can request dispensing of the reference drug rather than any biosimilar, regardless of interchangeability.4 Regardless, providers and payers will be tasked with challenging decisions in clinical practice and formulary placement, respectively.4, 5 The approved adalimumab biosimilars vary by concentration, citrate content, needle size, and potential for allergic reactions to latex. Providers and payers will need to consider these factors when determining appropriate biosimilars to utilize.4 Biosimilars can create opportunity for both patients and payers, including increasing access by lowering costs. Particularly where interchangeability exists, the ability for adalimumab biosimilars to compete with the reference drug will hinge largely on pricing and the potential for cost management. As of 2021, a year supply of Humira could cost as much as $84,000; the increased competition in this space may come with the promise of lowered costs.5 In the U.S., data suggests that biosimilars for other rheumatology biologic drugs have created competitive pricing landscapes.

Three rituximab biosimilars captured a 55% share of the Rituxan market from the end of 2019 to the first half of 2021, and by the end of that period, one of the biosimilars was offered at a 36% discount of the reference price.5 Overall, the average sales price of infliximab dropped nearly 50% from the end of 2016 to the first half of 2021.5 Rheumatology, specifically RA, has been a challenging and costly management space for payers. Due to the high costs associated with RA treatment, notably biologic drugs, many payers implement utilization management programs. A 2020 IQVIA analysis revealed that 80% of commercially insured patients attempting to fill a new prescription for RA or multiple sclerosis encountered a utilization management restriction, with more than 30% of these patients unable to gain approval for the new treatment.6 This same study found that 60% of new RA patients used cost-sharing assistance to help afford their RA treatment in 2018. The high costs to payers and patients alike in this category may present barriers to accessing treatment.6 The availability of biosimilars in the RA space has had an impact on prices, and the pending launch of adalimumab biosimilars shows some promise that further lowered costs for RA treatment are on the horizon.

*The EV-301 trial evaluated PADCEV vs investigator’s-choice chemotherapy in a randomized, multicenter, phase 3 trial of 608 patients with locally advanced or metastatic urothelial cancer who had previously received platinum-containing chemotherapy and a PD-1 or PD-L1 inhibitor. Patients were randomized 1:1 to either 1.25 mg/kg of PADCEV via IV infusion over 30 minutes on days 1, 8, and 15 of every 28-day cycle, or docetaxel at 75 mg/m2, paclitaxel at 175 mg/m2, or vinflunine at 320 mg/m2 on day 1 of every 21-day cycle. For both arms, treatment continued until radiographic disease progression or unacceptable toxicity.1,2 † Based on log-rank test. Stratification factors were ECOG PS, region and liver metastasis.1

IMPORTANT SAFETY INFORMATION BOXED WARNING: SERIOUS SKIN REACTIONS

• PADCEV can cause severe and fatal cutaneous adverse reactions including Stevens-Johnson syndrome (SJS) and Toxic Epidermal Necrolysis (TEN), which occurred predominantly during the first cycle of treatment, but may occur later.

• Closely monitor patients for skin reactions.

• Immediately withhold PADCEV and consider referral for specialized care for suspected SJS or TEN or severe skin reactions.

• Permanently discontinue PADCEV in patients with confirmed SJS or TEN; or Grade 4 or recurrent Grade 3 skin reactions.

INDICATION

PADCEV is indicated for the treatment of adult patients with locally advanced or metastatic urothelial cancer (mUC) who: • have previously received a programmed death receptor-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor and platinum-containing chemotherapy, or • are ineligible for cisplatin-containing chemotherapy and have previously received one or more prior lines of therapy.

WARNINGS AND PRECAUTIONS

Skin reactions Severe cutaneous adverse reactions, including fatal cases of SJS or TEN, occurred in patients treated with PADCEV. SJS and TEN occurred predominantly during the first cycle of treatment but may occur later. Skin reactions occurred in 55% of the 680 patients treated with PADCEV in clinical trials. Twenty-three percent (23%) of patients had maculo-papular rash and 33% had pruritus. Grade 3-4 skin reactions occurred in 13% of patients, including maculo-papular rash, rash erythematous, rash or drug eruption, symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), dermatitis bullous, dermatitis exfoliative, and palmarplantar erythrodysesthesia. In clinical trials, the median time to onset of severe skin reactions was 0.6 months (range: 0.1 to 6.4). Among patients experiencing a skin reaction leading to dose interruption who then restarted PADCEV (n=59), 24% of patients restarting at the same dose and 16% of patients restarting at a reduced dose experienced recurrent severe skin reactions. Skin reactions led to discontinuation of PADCEV in 2.6% of patients. Monitor patients closely throughout treatment for skin reactions. Consider topical corticosteroids and antihistamines, as clinically indicated. Withhold PADCEV and refer for specialized care for suspected SJS or TEN or for severe (Grade 3) skin reactions. Permanently discontinue PADCEV in patients with confirmed SJS or TEN, or for Grade 4 or recurrent Grade 3 skin reactions.

Hyperglycemia and diabetic ketoacidosis (DKA), including fatal events, occurred in patients with and without pre-existing diabetes mellitus, treated with PADCEV. Patients with baseline hemoglobin A1C ≥8% were excluded from clinical trials. In clinical trials, 14% of the 680 patients treated with PADCEV developed hyperglycemia; 7% of patients developed Grade 3-4 hyperglycemia. The incidence of Grade 3-4

hyperglycemia increased consistently in patients with higher body mass index and in patients with higher baseline A1C. Five percent (5%) of patients required initiation of insulin therapy for treatment of hyperglycemia. The median time to onset of hyperglycemia was 0.6 months (range: 0.1 to 20.3). Hyperglycemia led to discontinuation of PADCEV in 0.6% of patients. Closely monitor blood glucose levels in patients with, or at risk for, diabetes mellitus or hyperglycemia. If blood glucose is elevated (>250 mg/dL), withhold PADCEV. Pneumonitis Severe, life-threatening or fatal pneumonitis occurred in patients treated with PADCEV. In clinical trials, 3.1% of the 680 patients treated with PADCEV had pneumonitis of any grade and 0.7% had Grade 3-4. In clinical trials, the median time to onset of pneumonitis was 2.9 months (range: 0.6 to 6). Monitor patients for signs and symptoms indicative of pneumonitis, such as hypoxia, cough, dyspnea or interstitial infiltrates on radiologic exams. Evaluate and exclude infectious, neoplastic and other causes for such signs and symptoms through appropriate investigations. Withhold PADCEV for patients who develop persistent or recurrent Grade 2 pneumonitis and consider dose reduction. Permanently discontinue PADCEV in all patients with Grade 3 or 4 pneumonitis.

Peripheral neuropathy (PN) occurred in 52% of the 680 patients treated with PADCEV in clinical trials, including 39% with sensory neuropathy, 7% with muscular weakness and 6% with motor neuropathy; 4% experienced Grade 3-4 reactions.

PN occurred in patients treated with PADCEV with or without pre-existing PN. The median time to onset of Grade ≥2 PN was 4.6 months (range: 0.1 to 15.8 months). Neuropathy led to treatment discontinuation in 5% of patients. Monitor patients for symptoms of new or worsening peripheral neuropathy and consider dose interruption or dose reduction of PADCEV when PN occurs. Permanently discontinue PADCEV in patients who develop Grade ≥3 PN. Ocular disorders were reported in 40% of the 384 patients treated with PADCEV in clinical trials in which ophthalmologic exams were scheduled. The majority of these events involved the cornea and included events associated with dry eye such as keratitis, blurred vision, increased lacrimation, conjunctivitis, limbal stem cell deficiency, and keratopathy. Dry eye symptoms occurred in 34% of patients, and blurred vision occurred in 13% of patients, during treatment with PADCEV. The median time to onset to symptomatic ocular disorder was 1.6 months (range: 0 to 19.1 months). Monitor patients for ocular disorders. Consider artificial tears for prophylaxis of dry eyes and ophthalmologic evaluation if ocular symptoms occur or do not resolve. Consider treatment with ophthalmic topical steroids, if indicated after an ophthalmic exam. Consider dose interruption or dose reduction of PADCEV for symptomatic ocular disorders.

Infusion site extravasation Skin and soft tissue reactions secondary to extravasation have been observed after administration of PADCEV. Of the 680 patients, 1.6% of patients experienced skin and soft tissue reactions, including 0.3% who experienced Grade 3-4 reactions. Reactions may be delayed. Erythema, swelling, increased temperature, and pain worsened until 2-7 days after extravasation and resolved within 1-4 weeks of peak. Two patients (0.3%) developed

Major efficacy outcome measure: Median DOR§|| was 13.8 months with PADCEV (95% CI: 6.4, NE)1

The EV-201 trial (Cohort 2) was a single-arm, multicenter trial of 89 patients with locally advanced or metastatic urothelial cancer who had previously received a PD-1 or PD-L1 inhibitor and were cisplatin ineligible. Patients received 1.25 mg/kg of PADCEV via IV infusion over 30 minutes on days 1, 8, and 15 of every 28-day cycle and continued to receive treatment until disease progression or unacceptable toxicity. The major efficacy outcome measures, confirmed ORR and DOR, were assessed by BICR using RECIST v1.1. ORR consisted of confirmed CR and PR. CR was defined as the disappearance of all target and nontarget lesions. PR was defined as a ≥30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters.

Median duration of follow-up was 13.4 months.1,4,5 § Kaplan-Meier estimate of duration of response, defined as the time from first response to date of progression or death due to any cause, was assessed by BICR.4,6 || Based on patients (n=45) with a response by BICR.1

‡

extravasation reactions with secondary cellulitis, bullae, or exfoliation. Ensure adequate venous access prior to starting PADCEV and monitor for possible extravasation during administration. If extravasation occurs, stop the infusion and monitor for adverse reactions.

Embryo-fetal toxicity PADCEV can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception during PADCEV treatment and for 2 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with PADCEV and for 4 months after the last dose.

WARNINGS AND PRECAUTIONS Skin Reactions Severe cutaneous adverse reactions, including fatal cases of SJS or TEN occurred in patients treated with PADCEV. SJS and TEN occurred predominantly during the first cycle of treatment but may occur later.

Skin reactions occurred in 55% of the 680 patients treated with PADCEV in clinical trials.

Twenty-three percent (23%) of patients had maculopapular rash and 33% had pruritus.

Grade 3-4 skin reactions occurred in 13% of patients, including maculo-papular rash, rash erythematous, rash or drug eruption, symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), dermatitis bullous, dermatitis exfoliative, and palmar-plantar erythrodysesthesia. In clinical trials, the median time to onset of severe skin reactions was 0.6 months (range: 0.1 to 6.4 months). Among patients experiencing a skin reaction leading to dose interruption who then restarted PADCEV (n=59), 24% of patients restarting at the same dose and 16% of patients restarting at a reduced dose experienced recurrent severe skin reactions. Skin reactions led to discontinuation of PADCEV in 2.6% of patients.

Monitor patients closely throughout treatment for skin reactions. Consider topical corticosteroids and antihistamines, as clinically indicated.

Withhold PADCEV and refer for specialized care for suspected SJS, TEN or for severe (Grade 3) skin reactions.

Permanently discontinue PADCEV in patients with confirmed SJS or TEN; or Grade 4 or recurrent Grade 3 skin reactions.

Hyperglycemia Hyperglycemia and diabetic ketoacidosis (DKA), including fatal events, occurred in patients with and without pre-existing diabetes mellitus, treated with PADCEV. Patients with baseline hemoglobin A1C ≥ 8% were excluded from clinical trials. In clinical trials, 14% of the 680 patients treated with PADCEV developed hyperglycemia; 7% of patients developed Grade 3-4 hyperglycemia. The incidence of Grade 3-4 hyperglycemia increased consistently in patients with higher body mass index and in patients with higher baseline A1C. Five percent (5%) of patients required initiation of insulin therapy for treatment of hyperglycemia. The median time to onset of hyperglycemia was 0.6 months (range: 0.1 to 20.3 months). Hyperglycemia led to discontinuation of PADCEV in 0.6% of patients.

Closely monitor blood glucose levels in patients with, or at risk for, diabetes mellitus or hyperglycemia.

If blood glucose is elevated (> 250 mg/dL), withhold PADCEV. Pneumonitis Severe, life-threatening or fatal pneumonitis occurred in patients treated with PADCEV. In clinical trials, 3.1% of the 680 patients treated with PADCEV had pneumonitis of any grade and 0.7% had Grade 3-4. In clinical trials, the median time to onset of pneumonitis was 2.9 months (range: 0.6 to 6 months).

Monitor patients for signs and symptoms indicative of pneumonitis such as hypoxia, cough, dyspnea or interstitial infiltrates on radiologic exams. Evaluate and exclude infectious, neoplastic and other causes for such signs and symptoms through appropriate investigations.

Withhold PADCEV for patients who develop persistent or recurrent Grade 2 pneumonitis and consider dose reduction. Permanently discontinue PADCEV in all patients with Grade 3 or 4 pneumonitis.

Peripheral Neuropathy Peripheral neuropathy occurred in 52% of the 680 patients treated with PADCEV in clinical trials including 39% with sensory neuropathy, 7% with muscular weakness and 6% with motor neuropathy; 4% experienced Grade 3-4 reactions. Peripheral neuropathy occurred in patients treated with PADCEV with or without preexisting peripheral neuropathy. The median time to onset of Grade ≥ 2 peripheral neuropathy was 4.6 months (range: 0.1 to 15.8 months). Neuropathy led to treatment discontinuation in 5% of patients.

Monitor patients for symptoms of new or worsening peripheral neuropathy and consider dose interruption or dose reduction of PADCEV when peripheral neuropathy occurs.

Permanently discontinue PADCEV in patients who develop Grade ≥ 3 peripheral neuropathy.

Ocular Disorders Ocular disorders were reported in 40% of the 384 patients treated with PADCEV in clinical trials in which ophthalmologic exams were scheduled. The majority of these events involved the cornea and included events associated with dry eye such as keratitis, blurred vision, increased lacrimation, conjunctivitis, limbal stem cell deficiency, and keratopathy.

Dry eye symptoms occurred in 34% of patients, and blurred vision occurred in 13% of patients, during treatment with PADCEV. The median time to onset to symptomatic ocular disorder was 1.6 months (range: 0 to 19.1 months). Monitor patients for ocular disorders.

Consider artificial tears for prophylaxis of dry eyes and ophthalmologic evaluation if ocular symptoms occur or do not resolve. Consider treatment with ophthalmic topical steroids, if indicated after an ophthalmic exam. Consider dose interruption or dose reduction of PADCEV for symptomatic ocular disorders.

Infusion Site Extravasation Skin and soft tissue reactions secondary to extravasation have been observed after administration of PADCEV. Of the 680 patients, 1.6% of patients experienced skin and soft tissue reactions, including 0.3% who experienced Grade 3-4 reactions. Reactions may be delayed. Erythema, swelling, increased temperature, and pain worsened until 2-7 days

after extravasation and resolved within 1-4 weeks of peak. Two patients (0.3%) developed extravasation reactions with secondary cellulitis, bullae, or exfoliation. Ensure adequate venous access prior to starting PADCEV and monitor for possible extravasation during administration. If extravasation occurs, stop the infusion and monitor for adverse reactions.

PADCEV n=296 Adverse Reaction

Embryo-Fetal Toxicity Based on the mechanism of action and findings in animals, PADCEV can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of enfortumab vedotin-ejfv to pregnant rats during the period of organogenesis caused maternal toxicity, embryo-fetal lethality, structural malformations and skeletal anomalies at maternal exposures approximately similar to the clinical exposures at the recommended human dose of 1.25 mg/kg.

Advise patients of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception during treatment with PADCEV and for 2 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with PADCEV and for 4 months after the last dose.

Previously Treated Locally Advanced or Metastatic Urothelial Cancer EV-301 The safety of PADCEV was evaluated in EV-301 in patients with locally advanced or metastatic urothelial cancer (n=296) who received at least one dose of PADCEV 1.25 mg/kg and who were previously treated with a PD-1 or PD-L1 inhibitor and a platinum-based chemotherapy. Routine ophthalmologic exams were not conducted in EV-301. The median duration of exposure to PADCEV was 5 months (range: 0.5 to 19.4 months).

Serious adverse reactions occurred in 47% of patients treated with PADCEV. The most common serious adverse reactions (≥ 2%) were urinary tract infection, acute kidney injury (7% each) and pneumonia (5%). Fatal adverse reactions occurred in 3% of patients, including multiorgan dysfunction (1.0%), hepatic dysfunction, septic shock, hyperglycemia, pneumonitis and pelvic abscess (0.3% each).

Adverse reactions leading to discontinuation occurred in 17% of patients; the most common adverse reactions (≥ 2%) leading to discontinuation were peripheral neuropathy (5%) and rash (4%).

Adverse reactions leading to dose interruption occurred in 61% of patients; the most common adverse reactions (≥ 4%) leading to dose interruption were peripheral neuropathy (23%), rash (11%) and fatigue (9%).

Adverse reactions leading to dose reduction occurred in 34% of patients; the most common adverse reactions (≥ 2%) leading to dose reduction were peripheral neuropathy (10%), rash (8%), decreased appetite (3%) and fatigue (3%).

Immunogenicity As with all therapeutic proteins, there is a potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay.

Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease.

For these reasons, comparison of the incidence of antibodies in the trials described below with the incidence of antibodies in other trials or other enfortumab vedotin-ejfv products may be misleading.

Following administration of PADCEV 1.25 mg/kg; 16/590 (2.7%) patients tested positive for anti-therapeutic antibody (ATA) against enfortumab vedotin-ejfv at one or more postbaseline time points. Due to the limited number of patients with ATA against enfortumab vedotin-ejfv, no conclusions can be drawn concerning a potential effect of immunogenicity on efficacy, safety or pharmacokinetics.

DRUG INTERACTIONS

USE IN SPECIFIC POPULATIONS Pregnancy Risk Summary Based on the mechanism of action and findings in animals, PADCEV can cause fetal harm when administered to a pregnant woman. There are no available human data on PADCEV use in pregnant women to inform a drug-associated risk. In an animal reproduction study, administration of enfortumab vedotin-ejfv to pregnant rats during organogenesis caused maternal toxicity, embryo-fetal lethality, structural malformations and skeletal anomalies at maternal exposures approximately similar to the exposures at the recommended human dose of 1.25 mg/kg. Advise patients of the potential risk to the fetus.

The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%-4% and 15%-20%, respectively.

Lactation Risk Summary There are no data on the presence of enfortumab vedotin-ejfv in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise lactating women not to breastfeed during treatment with PADCEV and for at least 3 weeks after the last dose.

Females and Males of Reproductive Potential Pregnancy testing Verify pregnancy status in females of reproductive potential prior to initiating PADCEV treatment.

Contraception Females PADCEV can cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective contraception during PADCEV treatment and for 2 months after the last dose.

Males Advise male patients with female partners of reproductive potential to use effective contraception during treatment with PADCEV and for 4 months after the last dose.

Infertility Males Based on findings from animal studies, PADCEV may impair male fertility.

Pediatric Use Safety and effectiveness of PADCEV in pediatric patients have not been established.

Geriatric Use Of the 680 patients treated with PADCEV in clinical trials, 440 (65%) were 65 years or older and 168 (25%) were 75 years or older. No overall differences in safety or effectiveness were observed between these patients and younger patients.

Hepatic Impairment Avoid the use of PADCEV in patients with moderate or severe hepatic impairment (total bilirubin > 1.5 x ULN and AST any). PADCEV has only been studied in a limited number of patients with moderate hepatic impairment (n=3) and has not been evaluated in patients with severe hepatic impairment. In another ADC that contains MMAE, the frequency of ≥ Grade 3 adverse reactions and deaths was greater in patients with moderate (Child-Pugh B) or severe (Child-Pugh C) hepatic impairment compared to patients with normal hepatic function. No adjustment in the starting dose is required when administering PADCEV to patients with mild hepatic impairment (total bilirubin 1 to 1.5 × ULN and AST any, or total bilirubin ≤ ULN and AST >ULN).

Metastatic Bladder Cancer: Treatment Challenges and Opportunities In the population of cisplatin-ineligible mUC patients, there remains a high unmet need. Recent studies for first-line standard of care therapies have not demonstrated significant improvements in OS, PFS, or ORR. About 10-15% of patients diagnosed with bladder cancer present with metastasis.1 The most common form of bladder cancer is urothelial carcinoma (UC), which accounts for about 95% of all bladder cancer cases.2 Metastatic urothelial carcinoma (mUC) is an aggressive disease with poor prognosis. Less than 8% of patients with mUC survive five years after diagnosis.3 mUC is one of the leading causes of genitourinary cancer-related mortality.1

Treatment Challenges in mUC Population Lindsay Speicher, JD Project Manager, Specialty Magellan Rx Management

Cisplatin is the established standard of care in the neoadjuvant setting in cases of unresectable or mUC.4 However, about 55% of patients presenting with mUC are determined cisplatin-ineligible;5 these patients have worse outcomes compared to patients who are eligible for cisplatin therapy (8.6 months versus 14.4 months, respectively).5 In the population of cisplatin-ineligible mUC patients, there remains a high unmet need. Recent studies for first-line standard of care therapies have not demonstrated significant improvements in overall survival (OS), progression-free survival (PFS), or overall response rate (ORR).6 While cisplatin-based chemotherapy is the standard first-line treatment for patients with mUC, about half of the patients with mUC are excluded from this treatment due to multiple factors, including, but not limited to, renal dysfunction, neuropathy, or poor performance status.7 In many cases, first-line therapy may be the only therapy these patients are able to receive. An estimated 60% of cisplatin-ineligible patients do not receive first-line therapy, and fewer than half receive second-line treatment.5 About half of the patients who start on platinum-based chemotherapy are eligible to and go on to receive maintenance therapy. Notably, maintenance therapy has only been shown to provide incremental OS when looking at OS outcomes before and after maintenance introduction into the treatment paradigm.8 Pembrolizumab and atezolizumab have been standard first-line therapy options for cisplatinineligible patients with high PD-L1 expression. Immune checkpoint inhibitors such as PD-1 and PD-L1

Enfortumab Vedotin-EJFV (PADCEV) In 2021, the FDA approved enfortumab vedotin-EJFV, a Nectin4-directed antibody and microtubule inhibitor conjugate, for adult patients with locally advanced or mUC who have previously received a PD-1 or PD-L1 inhibitor and platinum containing chemotherapy or who are ineligible for cisplatin-containing

chemotherapy and have previously received one or more prior lines of therapy.10 Enfortumab vedotin-EJFV (EV) was previously approved through the FDA accelerated approval process in 2019 for patients with locally advanced or mUC who have received a PD-1 or PD-L1 inhibitor and a platinum-containing chemotherapy in the neoadjuvant/adjuvant, locally advanced, or metastatic setting.10 Approval was based on results from Trial EV-301, an openlabel, randomized, multicenter trial of 608 patients with locally advanced or mUC who received prior PD-1 or PD-L1 inhibitor and platinum-based chemotherapy.11 Patients were randomized to receive EV 1.25 mg/kg on days 1, 8, and 15 of a 28-day cycle or one of the following single-agent chemotherapies: docetaxel, paclitaxel, or vinflunine.11 The primary efficacy end point of the trial was OS, with secondary end points including PFS and ORR.11 Patients in the EV arm had a median OS of 12.9 months, compared to 9.0 months for those receiving chemotherapy.11 Median PFS was higher for patients in the EV arm compared to those receiving chemotherapy (5.6 months versus 3.7 months, respectively).11 The ORR in patients receiving EV was 40.6% compared to 17.9% for patients receiving chemotherapy.11 Common adverse reactions associated with EV treatment included rash, aspartate aminotransferase increase, glucose increase, creatinine increase, fatigue, peripheral neuropathy, lymphocytes decrease, alopecia, decrease in appetite, hemoglobin decrease, diarrhea, sodium decrease, nausea, pruritus, phosphate decrease, dysgeusia, alanine aminotransferase increase, anemia, albumin decrease, neutrophils decrease, urate increase, lipase increase, platelets decrease, weight decrease, and dry skin.10, 11 Other studies have shown the efficacy of EV in treating mUC. In EV-201, the efficacy and safety of EV in the post-immunotherapy setting in cisplatin-ineligible patients with locally advanced or mUC were investigated.12 The primary end point of EV-201 was confirmed ORR; results showed ORR was 52% with 18 of 89 patients achieving a complete response and 28 achieving partial response.12 The phase 3, randomized EV-301 trial showed that EV prolonged median OS by nearly four months and reduced risk of death by 30%. Patient reported outcomes from EV-301 showed that chemotherapy was associated with greater deterioration and variability in quality of life.13 Patients receiving EV reported reduction in pain symptoms when compared to chemotherapy treated patients; however, treatment with EV was associated with increased patient-reported appetite loss.12 There is an ongoing study (KEYNOTE-869) investigating the safety and anti-tumor activity of EV as monotherapy in the first-line setting and with PD-1 inhibitor pembrolizumab and/or chemotherapy in mUC.14

Combination Treatment with Enfortumab VedotinEJFV and Pembrolizumab There is evidence that a combination of EV and pembrolizumab may provide value for mUC patients who are cisplatin-ineligible.14 Clinical data from an ongoing trial suggests that EV plus pembrolizumab may have the potential to induce greater antitumor activity in locally advanced or mUC compared with either agent alone.14 In February 2020, the combination therapy of EV and pembrolizumab was granted Breakthrough designation for cisplatin-ineligible patients with locally advanced or mUC in the first-line setting.1 The ongoing trial has demonstrated that the combination therapy is encouraging and durable activity with a tolerable and stable safety profile in cisplatin-ineligible patients with locally advanced or mUC in the first-line setting.15 In August 2022, results from the phase 1b/2 EV-103 clinical trial show EV in combination with pembrolizumab as first-line treatment in patients with locally advanced or mUC who are ineligible for cisplatin-based chemotherapy were published.16

There is evidence that a combination of enfortumab vedotin and pembrolizumab may provide value for mUC patients who are cisplatinineligible.

Results showed that patients treated with the combination enfortumab vedotin plus pembrolizumab regimen had a 73.3% confirmed ORR and a 15.6% complete response rate.16 Median duration of response and overall survival were 25.6 months and 26.1 months, respectively.16

Payer Impact A 2020 study of Medicare claims assessed the lifetime economic burden of UC.18 Results showed that stage III UC had the highest cost per patient, driven by intensive care with multi-modal management, including cystectomy and multi-drug chemotherapy.18 Stage IV UC had the lowest cost per patient, which could be due to the less intense therapy.18 However, across all stages, hospitalizations contributed the greatest spend to the lifetime cost. Access to and utilization of treatments that may decreased hospitalizations – in frequency and duration – may play a role in lowering costs.18 Over the years, multiple immune checkpoint inhibitors (ICIs) have received approval as single agents or following chemotherapy in

early and late-stage UC. Without definitive cost-effectiveness data, payers are concerned about the added spend for this therapy class.

As ICIs tend to have high costs, payers may seek pricing discounts or other management strategies.19 Although UC accounts for only 4% of new cancer cases in the U.S. and the number of mUC cases is even smaller, higher cost treatments tend to be a concern for payers. The population of cisplatin-ineligible mUC patients only accounts for about half of the mUC cases and may require different treatment and management for improved outcomes; due to the small size of this subset of the UC population, these patients may not be a high priority in terms of payer management. However, as the long-term outcomes of ICIs and treatments for mUC continue to be examined, payers may continue to consider and evaluate appropriate access and management of this category.

Gene Therapy: Rare Disease Management As the number of gene therapies in the market increases, payers and manufacturers will continue to collaborate to transform reimbursement and payment models.

While there are around 7,000 identified rare diseases, only about 5% have FDA-approved treatment.1 As more than 80% of rare diseases have a known monogenic cause, gene therapies present particularly promising treatment potential. Traditional small molecule drugs have worked to minimize symptoms, but most have not worked to cure the underlying disease, which can lead to frequent administration of the drug or multiple drugs required for proper disease management.1 Successful gene therapies may present a single-dose, curative treatment option for those living with otherwise difficult-to-treat rare diseases.1

Carly Rodriguez, Pharm.D., FAMCP Vice President & Chief Pharmacy Officer

Potentially 90 new gene and cellular therapies could receive approval by 2031.2 According to an MIT Report, this wave of new approvals would result in $30 billion in healthcare spending.2 A recent survey of researchers knowledgeable about genetic therapies for rare diseases found that respondents believed gene therapy would be the standard of care for rare genetic diseases before 20363—a major shift in the treatment landscape. Though there was a small delay in the development and approvals of some gene therapy products, a wave of products is nearing approval and will be coming to market.4

GENE THERAPY | Continued

Currently Available Gene Therapies Since the approval of voretigene neparvovec-rzyl (LUXTURNA®, Spark Therapeutics) for the treatment of confirmed biallelic RPE65 mutation-associated retinal dystrophy in 2017, other advances in gene therapy have created opportunity and promise for many rare diseases. The FDA approved onasemnogene abeparvovec-xioi (ZOLGENSMA®, Novartis) for spinal muscular atrophy (SMA) in 2019.

Most recently, betibeglogene autotemcel (Zynteglo®, bluebird bio) was approved for beta thalassemia. The current pipeline of gene therapies being reviewed and investigated is expansive (Table 1) and include Duchenne muscular dystrophy (DMD), sickle cell disease, hemophilia, epidermolysis bullosa, Huntington’s disease, choroideremia, cerebral adrenoleukodystrophy, and several more.

Recent Approvals Betibeglogene Autotemcel (Zynteglo®) In August 2022, the U.S. Food and Drug Administration approved betibeglogene autotemcel (beti-cel) (Zynteglo®, bluebird bio) for adult and pediatric patients with beta thalassemia who require regular blood cell transfusions.5 Beti-cel is a one-time gene therapy administered as a single dose, customized using the patient’s own bone marrow stem cells that are genetically modified to produce functional beta globin.5 This gene therapy was granted a rare pediatric disease voucher, in addition to receiving Priority Review, Fast Track, Breakthrough Therapy, and Orphan designations. FDA approval was based on safety and effectiveness results from two multicenter clinical studies of adult and pediatric patients with beta thalassemia requiring regular blood transfusions. Effectiveness was established based on the achievement of transfusion independence: when a patient maintains a predetermined level of hemoglobin without needing any red blood cell transfusions for at least 12 months. Of the 41 patients receiving beti-cel in the studies, 89% achieved transfusion independence.5 Common adverse reactions associated with beti-cel treatment included reduced platelet and other blood cell levels, as well as mucositis, febrile neutropenia, vomiting, pyrexia, alopecia, epistaxis, abdominal pain, musculoskeletal pain, cough, headache, diarrhea, rash, constipation, nausea, decreased appetite, pigmentation disorder, and pruritus. Treatment with beti-cel presents a potential risk of blood cancer, however, no cases were seen in studies with beticel. Hypersensitivity reactions during beti-cel administration as well as thrombocytopenia and bleeding should be monitored.5 Patients treated with beti-cel should undergo regular blood monitoring for at least 15 years for any evidence of cancer.

A report in June 2022, by the Institute for Clinical and Economic Review, determined that beti-cel provides net health benefits to patients with

18 | Magellan Rx Report | Fall 2022

beta thalassemia.6 Cost-effectiveness modeling found that treatment with beti-cel met commonly accepted value thresholds at a price of up to $2.77 million with an 80% payback option for patients who do not achieve and maintain transfusion independence over a five-year period.6 The initial price of beti-cel is $2.8 million.

Elivaldogene Autotemcel (SKYSONA®)7 In September 2022, elivaldogene autotemcel (eli-cel) (SKYSONA®, bluebird bio) received FDA accelerated approval to slow the progression of neurologic dysfunction in boys aged 4 to 17 years with early, active cerebral adrenoleukodystrophy (CALD). The FDA also lifted the clinical hold that was put in place in August 2021.

Approval was based on data from the phase 2/3 ALD-102 and phase 3 ALD-104 studies. In the studies, patients treated with eli-cel were assessed using neurologic function score (NFS) associated with CALD progerssion. Patients treated with eli-cel estimated 72% likelihood of Major Functional Disabilities (MFD)-free survival at 24 months from the time of first NFS>1 versus 43% in untreated patients.

Adverse reactions associated with eli-cel included mucositis, nausea, vomiting, febrile neutropenia, alopecia, decreased appetite, abdominal pain, constipation, pyrexia, diarrhea, headache, and rash.

The most common Grade 3 or 4 abnormalities associated with eli-cel include leukopenia, lymphopenia, thrombocytopenia, neutropeia, anemia, and hypokalemia.

Payer Management Gene therapies carry particularly high price tags; for example, onasemnogene abeparvovec for SMA has a list price of $2.125 million per dose and beti-cel has a price of $2.8 million for a single dose.4 As more gene therapies are approved and become available for rare or orphan diseases, high prices may be expected beyond that of conventional medical interventions.4 Actively monitoring the gene therapy pipeline and tracking data on newly approved products and products under review will be key to determining appropriate access and management strategies as gene therapy products launch.4 Managing cost and ensuring access to these potentially curative therapies requires collaboration between payers and pharmaceutical manufacturers; the need for consensus for coverage of these gene therapies is clear.2 In 2020, healthcare leaders from government, industry, and academia formed a work group to establish a guideline for payment models for advanced therapies.2 The work group highlighted key challenges in managing coverage and payment for these therapies, including the difficulty in assessing accurate prices for short-term drugs that

could have long-term, potentially curative impact. In some cases, the long-term impact of the newer gene therapies is still unproven, which must be accounted for in drug pricing and management.

Future unknowns must also be considered; while the gene therapies currently approved largely focus on rare diseases, there may be potential uses not yet explored for the therapies, which could lead to increased utilization across multiple disease states.2 Still, payers, providers, and manufacturers have sought solutions.

Alternative payment models may help finance gene therapies.

Some of these include outcomes- or milestone-based agreements, subscription payment models, and risk pools. A milestone-based arrangement requires a payer to pay a certain amount up front with partial reimbursement guaranteed if the therapy fails to provide the intended outcome within a certain timeframe.8 Subscriptionbased models include a fixed fee for unlimited access to certain therapies; the payer takes on the risk as it guarantees to provide as much therapy as required.8 The subscription-based model potentially allows payers to manage the actuarial fluctuations that occur with the funding of gene therapies.8 One manufactureradvanced model prices therapies solely on the intrinsic value of the product and returns all cost offsets to the payers. Vastly different from a typical reimbursement model, this arrangement could ease

some payer concerns regarding cost management associated with gene therapies.8 In 2021, about 12% of payers implemented more than 10 valuebased contracts with manufacturers involving outcomes-based measures.9 A 2020 survey of managed care professionals showed that 62% of U.S. payers currently use traditional strategies, such as formulary or utilization management tools, to manage cell and gene therapies.10 Many payers (66% of respondents) plan to leverage reinsurance in the near future. Respondents also noted they anticipate an increase in the utilization of value- and outcomesbased contracting and installment payments as techniques to manage gene therapies.10 As the number of gene therapies in the market increases, payers and manufacturers will continue to collaborate to transform reimbursement and payment models.11 Cited concerns around the current reimbursement models include limitations around program complexity, burden of information tracking, insurance, regulatory barriers, and government pricing and reporting requirements.11 Collaborative development of creative payment models by all stakeholders will be key to effectively manage these treatments, allow access to the patient population, and ease the financial burden.

Age-Related Macular Degeneration and Diabetic Macular Edema: Treatment Advances and Payer Strategies Due to the high degree of variability in eye diseases, managing these conditions requires flexibility and strong provider engagement.

Age-Related Macular Degeneration (AMD) Age-related macular degeneration (AMD) is an eye disease that affects approximately 15 million Americans.1 AMD occurs when aging causes damage to the macula; it is the leading cause of vision loss for older adults. Those at highest risk for AMD are older than 55 years, have a family history of AMD, are white, or smoke. While it does not cause complete vision loss, it does cause loss of central vision, which can make it difficult to see faces, read, drive, or do other daily activities.1

Scott McLelland, Pharm.D. VP, Commercial and Specialty Pharmacy Florida Blue

There are two types of AMD: dry and wet. Dry AMD (dAMD) is also called atrophic AMD and occurs when the macula thins with age. The three stages of dAMD—early, intermediate, and late—typically progress slowly over several years. Wet AMD (wAMD), otherwise known as advanced neovascular AMD, is a less common form of late AMD that causes faster vision loss. wAMD is always late-stage; however, any stage of dAMD can develop into wAMD, which occurs when abnormal blood vessels grow in the back of the eye and damage the macula. While there are no available treatments for late-stage dAMD, there are treatment options for wAMD.1

growth or edema.1 Currently, there are seven anti-VEGF treatments approved by the U.S. Food and Drug Administration (FDA) and available to treat AMD: brolucizumab (BEOVU®), ranibizumab-nuna (BYOOVIZTM), ranibizumab-qgrn (CIMERLITM), aflibercept (EYLEA®), ranibizumab (LUCENTIS®), ranibizumab implant (SusvimoTM), faricimab (Vabysmo®). Off-label bevacizumab (Avastin®) is also successfully used to treat wAMD. The landscape of drugs in this category has become more dynamic with the entrace of biosimilars along with historical use of compounded Avastin®.1

DME

Symptoms of AMD vary depending on the stage. Early dAMD presents with no symptoms. While some people with intermediate dAMD have no symptoms, others may notice mild blurriness or trouble seeing in low light. Symptoms of late AMD, whether wet or dry, can include straight lines looking wavy or crooked, a blurry area near the center of vision that gets bigger over time, colors that appear less bright, and trouble seeing in low lighting.1

Often, DME is treated by first addressing the underlying cause— such as high blood sugar or high blood pressure—which can help prevent further damage or progression.2 After this is resolved, an ophthalmologist or retina specialist will address the damage to the retina. Anti-VEGF treatments are often used as a first-line treatment in patients with DME. Other treatments, such as focal-grid macular laser surgery, may help to slow leaking and reduce swelling.2

Ophthalmologists check for AMD as part of a comprehensive dilated eye exam. Some may recommend optical coherence tomography.1

Recent Approvals

Diabetic Macular Edema (DME) Diabetic macular edema (DME) is the buildup of fluid in the macula caused by diabetic retinopathy, a complication of diabetes.2 Diabetic retinopathy is the most common diabetic eye disease; it is the leading cause of irreversible blindness in adult Americans.

Typically, diabetic retinopathy affects both eyes, and most commonly, DME is the cause of vision loss in those with diabetic retinopathy.2 The risk of blindness increases with poor blood sugar control and other associated medical conditions including high blood pressure. DME is most likely to occur as diabetic retinopathy progresses; however, it can occur at any stage of the condition.2 An estimated 7.7 million Americans live with diabetic retinopathy, with about 750,000 of those having DME.2

Faricimab-svoa (Vabysmo®) In January 2022, the FDA approved faricimab-svoa (Vabysmo®, Genentech) for the treatment of wAMD and DME. Faricimab-svoa

Stay ahead of trend:

Treatment Landscape AMD Treatment depends on the type and stage of disease.1 While there is no treatment for patients with early or intermediate AMD, ophthalmologists may recommend vitamins or dietary supplements that may help to prevent further progression of AMD. The goal of treatment for wAMD is prevention of further vision loss.1 Anti-VEGF treatments can be injected in the eye to reduce new blood vessel

treatments are administered one to four months apart in the first year, following four initial monthly doses, based on evaluation of the patient’s anatomy and outcomes.3 FDA approval was based on results from four phase 3 studies in wAMD and DME.3 Two phase 3 studies evaluated the efficacy, durability, and safety of faricimabsvoa (TENAYA and LUCERNE).4 The primary end point of these

studies was change in best-corrected visual acuity (BCVA). The two trials included 1,329 patients randomized to receive faricimab or aflibercept.4 In patients receiving faricimab at intervals spanning up to four months, BCVA change from baseline was noninferior to patients treated with aflibercept every two months. Ocular adverse events occurred at a comparable incidence across the groups.4

PEOPLE Make The Difference

The YOSEMITE and RHINE phase 3 trials evaluated efficacy, durability, and safety of faricimab in patients with DME.5 In these trials, 1,891 patients were randomized to receive faricimab every eight weeks, faricimab over a personalized treatment interval, or aflibercept every eight weeks.6 The primary end point was mean change in BCVA at one year, average over weeks 48, 52, and 56.6 Patients treated with faricimab every eight weeks achieved a BCVA noninferior to patients treated with aflibercept every eight weeks.

Incidence in ocular adverse events were similar between faricimab and aflibercept groups.6 The trials have shown that faricimab-svoa is generally well-tolerated, with the most common adverse event being conjunctival hemorrhage.7

Ranibizumab 100 mg/mL Injection (Susvimo®) The FDA approved 100 mg/mL ranibizumab injection (Susvimo®, Genentech) for the treatment of wAMD in October 2021. The product is approved for intravitreal use via ocular implant for patients who have previously responded to at least two anti-VEGF injections.8 Susvimo® is the first and only FDA-approved treatment for wAMD that offers as few as two treatments per year. Typically, anti-VEGF treatment for wAMD requires injections administered as often as monthly. This ranibizumab injection offers a one-time implant, or Port Delivery System (PDS), that is refilled about every six months.8 The Archway study evaluated the efficacy and safety of the PDS with ranibizumab relative to monthly ranibizumab

injections, measuring BCVA following 36-40 weeks of treatment.9 The PDS with ranibizumab was found to be non-inferior to monthly injections; patients receiving monthly injections gained 0.5 letters on average compared to 0.2 letters on average for patient in the PDS group.9

Launch of Ranibizumab Biosimilars In September 2021, the FDA approved ranibizumab-nuna (Byooviz®, Biogen) for wAMD, which was the first biosimilar referencing ranibizumab (Lucentis®, Genentech) and the first ophthalmology biosimilar in the U.S. market. The biosimilar launched in the U.S. markets in June.10 Byooviz is listed for $1,130 per single-use 0.5 mg vial to be administered intravitreally; this list price will be around 15% lower in price than the ASP of the reference drug.10 In August, the FDA approved ranibizumab-eqrn (Cimerli®, Coherus Biosciences) as the first and only biosimilar product interchangeable with the reference drug for all five indications – wAMD, macular edema following retinal vein occlusion, DME, diabetic retinpathy, and myopic choroidal neovascularization.11 In a head-to-head study, the ranibizumab-eqrn met its primary endpoint of change from baseline in BCVA at week 8 compared to the reference product. Overall safety and immunogenicity profile was comparable with the reference product as well. This biosimilar

AMD AND DME | Continued

is expected to become available on the market in early October.11 The interchangeability designation will allow ranibizumab-eqrn to be substituted without the intervention of the provider, subject to state pharmacy laws.11 A June 2022 survey suggested a split amongst ophthalmologists in regard to the decision to utilize Byooviz® with their patients within the first three months of launch.12 Notably, the survey was conducted before the approval of interchangeable biosimilar, Cimerli®. Still, some ophthalmologists may hesitate to switch patients who are doing well on the reference drug regardless of payer preference and savings.12 While pricing is important to set a biosimilar apart, demonstrating value by engaging providers, payers, and patients in an effort to facilitate access and provide education support will be key; interchangeability will also be a factor in distinguishing biosimilar products.13 The launch of this biosimilar presents opportunity for savings and competitive pricing within the ophthalmology space.12

Payer Management of AMD and DME When it comes to managing patients with eye diseases, flexibility is key.

Appropriate treatment can be patient specific; especially in patients with DME and AMD, there is a high degree of variability.14 Treatment decisions and treatment intervals may vary between patients, so proper management will require provider engagement.14 Additionally, managing the underlying cause can be crucial to achieving positive outcomes. Especially in patients with DME, controlling blood sugar

and encouraging healthier diets and exercise can potentially have a positive impact on the treatment of the eye disease.14 Proper and timely diagnosis and treatment is critical to improving long-term outcomes as well as managing costs.15 Both the clinical and economic impacts of delaying treatment in patients with these eye diseases can be significant and often irreversible. Any delay, such as improper dosing or intervals between treatments, can lead to complications that will require additional, more expensive treatments in the long-term, which can tremendously increase costs.15 During the COVID-19 pandemic, many patients were not receiving treatment; as provider offices began to reopen and patients returned to resume treatments, there were many instances of severe complications that resulted in permanent vision loss.15 This instance illustrated the real cost of delays or pauses in treatment for patients with eye disease.

Early detection, provider education, and access to appropriate treatments can lead to better outcomes and more effective cost management in these populations.15 While treatment options in this category are growing, bevacizumab (Avastin®) remains a cost-effective therapy for payers to initially consider (Table 2). Notably, the cost for compounded bevacizumab is considerably less than other therapies and many payers do not currently require compounded bevacizumab prior authorization where the drug is clinically appropriate. Biosimilars entering the market can compete in this space as they will be FDA approved, leading to fair reimbursement. This category is seeing new entrants providing potential for better treatment, extended outcomes, and improved cost management.

IMPORTANT SAFETY INFORMATION Ensure that 2 doses of tocilizumab are available prior to CYTOKINE RELEASE SYNDROME (continued) YESCARTA infusion. Monitor patients for signs and symptoms of Key manifestations of CRS (≥ 10%) in all patients combined CRS at least daily for 7 days at the certified healthcare facility, included fever (85%), hypotension (40%), tachycardia (32%), and for 4 weeks thereafter. Counsel patients to seek immediate chills (22%), hypoxia (20%), headache (15%), and fatigue (12%). Serious events that may be associated with CRS include medical attention should signs or symptoms of CRS occur at cardiac arrhythmias (including atrial fibrillation and ventricular any time. At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids tachycardia), renal insufficiency, cardiac failure, respiratory as indicated. failure, cardiac arrest, capillary leak syndrome, multi-organ failure, and hemophagocytic lymphohistiocytosis/macrophage NEUROLOGIC TOXICITIES activation syndrome.

Neurologic toxicities (including immune effector cell-associated The impact of tocilizumab and/or corticosteroids on the neurotoxicity syndrome) that were fatal or life-threatening incidence and severity of CRS was assessed in 2 subsequent occurred. Neurologic toxicities occurred in 78% (330/422) of cohorts of LBCL patients in ZUMA-1. Among patients who patients with NHL receiving YESCARTA, including ≥ Grade 3 in received tocilizumab and/or corticosteroids for ongoing Grade 25%. Neurologic toxicities occurred in 87% (94/108) of patients 1 events, CRS occurred in 93% (38/41), including 2% (1/41) with with LBCL in ZUMA-1, including ≥ Grade 3 in 31% and in 74% Grade 3 CRS; no patients experienced a Grade 4 or 5 event. The (124/168) of patients in ZUMA-7 including ≥ Grade 3 in 25%. median time to onset of CRS was 2 days (range: 1-8 days) and The median time to onset was 4 days (range: 1-43 days) and the median duration of CRS was 7 days (range: 2-16 days). the median duration was 17 days for patients with LBCL in Prophylactic treatment with corticosteroids was administered ZUMA-1. The median time to onset for neurologic toxicity was to a cohort of 39 patients for 3 days beginning on the day of 5 days (range: 1-133 days) and median duration was 15 days infusion of YESCARTA. Thirty-one of the 39 patients (79%) in patients with LBCL in ZUMA-7. Neurologic toxicities occurred developed CRS and were managed with tocilizumab and/or in 77% (112/146) of patients with iNHL, including ≥ Grade 3 in therapeutic doses of corticosteroids with no patients developing 21%.

IMPORTANT SAFETY INFORMATION NEUROLOGIC TOXICITIES (continued) The most common neurologic toxicities (≥ 10%) in all patients combined included encephalopathy (50%), headache (43%), tremor (29%), dizziness (21%), aphasia (17%), delirium (15%), and insomnia (10%). Prolonged encephalopathy lasting up to 173 days was noted. Serious events, including aphasia, leukoencephalopathy, dysarthria, lethargy, and seizures occurred. Fatal and serious cases of cerebral edema and encephalopathy, including late-onset encephalopathy, have occurred.

The impact of tocilizumab and/or corticosteroids on the incidence and severity of neurologic toxicities was assessed in 2 subsequent cohorts of LBCL patients in ZUMA-1. Among patients who received corticosteroids at the onset of Grade 1 toxicities, neurologic toxicities occurred in 78% (32/41) and 20% (8/41) had Grade 3 neurologic toxicities; no patients experienced a Grade 4 or 5 event. The median time to onset of neurologic toxicities was 6 days (range: 1-93 days) with a median duration of 8 days (range: 1-144 days). Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of YESCARTA. Of those patients, 85% (33/39) developed neurologic toxicities; 8% (3/39) developed Grade 3, and 5% (2/39) developed Grade 4 neurologic toxicities.

The median time to onset of neurologic toxicities was 6 days (range: 1-274 days) with a median duration of 12 days (range: 1-107 days). Prophylactic corticosteroids for management of CRS and neurologic toxicities may result in higher grade of neurologic toxicities or prolongation of neurologic toxicities, delay the onset and decrease the duration of CRS. Monitor patients for signs and symptoms of neurologic toxicities at least daily for 7 days at the certified healthcare facility, and for 4 weeks thereafter, and treat promptly.

REMS Because of the risk of CRS and neurologic toxicities, YESCARTA is available only through a restricted program called the YESCARTA and TECARTUS REMS Program which requires that: Healthcare facilities that dispense and administer YESCARTA must be enrolled and comply with the REMS requirements and must have on-site, immediate access to a minimum of 2 doses of tocilizumab for each patient for infusion within 2 hours after YESCARTA infusion, if needed for treatment of CRS. Certified healthcare facilities must ensure that healthcare providers who prescribe, dispense, or administer YESCARTA are trained about the management of CRS and neurologic toxicities. Further information is available at www.YescartaTecartusREMS.com or 1-844-454-KITE (5483).

HYPERSENSITIVITY REACTIONS Allergic reactions, including serious hypersensitivity reactions or anaphylaxis, may occur with the infusion of YESCARTA. SERIOUS INFECTIONS Severe or life-threatening infections occurred. Infections (all grades) occurred in 45% of patients with NHL. ≥ Grade 3 infections occurred in 17% of patients, including ≥ Grade 3 infections with an unspecified pathogen in 12%, bacterial infections in 5%, viral infections in 3%, and fungal infections in 1%. YESCARTA should not be administered to patients with clinically significant active systemic infections. Monitor patients for signs and symptoms of infection before and after infusion and treat appropriately. Administer prophylactic antimicrobials according to local guidelines.

Febrile neutropenia was observed in 36% of patients with NHL and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broadspectrum antibiotics, fluids, and other supportive care as medically indicated.

In immunosuppressed patients, including those who have received YESCARTA, life-threatening and fatal opportunistic infections including disseminated fungal infections (e.g., candida sepsis and aspergillus infections) and viral reactivation (e.g., human herpes virus-6 [HHV-6] encephalitis and JC virus progressive

multifocal leukoencephalopathy [PML]) have been reported. The possibility of HHV-6 encephalitis and PML should be considered in immunosuppressed patients with neurologic events and appropriate diagnostic evaluations should be performed.

Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, has occurred in patients treated with drugs directed against B cells, including YESCARTA. Perform screening for HBV, HCV, and HIV and management in accordance with clinical guidelines before collection of cells for manufacturing.

PROLONGED CYTOPENIAS Patients may exhibit cytopenias for several weeks following lymphodepleting chemotherapy and YESCARTA infusion. ≥ Grade 3 cytopenias not resolved by Day 30 following YESCARTA infusion occurred in 39% of all patients with NHL and included neutropenia (33%), thrombocytopenia (13%), and anemia (8%).

Monitor blood counts after infusion.

HYPOGAMMAGLOBULINEMIA B-cell aplasia and hypogammaglobulinemia can occur.

Hypogammaglobulinemia was reported as an adverse reaction in 14% of all patients with NHL. Monitor immunoglobulin levels after treatment and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement. The safety of immunization with live viral vaccines during or following YESCARTA treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during YESCARTA treatment, and until immune recovery following treatment.

SECONDARY MALIGNANCIES Secondary malignancies may develop. Monitor life-long for secondary malignancies. In the event that one occurs, contact Kite at 1-844-454-KITE (5483) to obtain instructions on patient samples to collect for testing.

EFFECTS ON ABILITY TO DRIVE AND USE MACHINES Due to the potential for neurologic events, including altered mental status or seizures, patients are at risk for altered or decreased consciousness or coordination in the 8 weeks following YESCARTA infusion. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, during this initial period.

ADVERSE REACTIONS The most common non-laboratory adverse reactions (incidence ≥ 20%) in patients with LBCL in ZUMA-7 included fever, CRS, fatigue, hypotension, encephalopathy, tachycardia, diarrhea, headache, musculoskeletal pain, nausea, febrile neutropenia, chills, cough, infection with unspecified pathogen, dizziness, tremor, decreased appetite, edema, hypoxia, abdominal pain, aphasia, constipation, and vomiting.

WARNING: CYTOKINE RELEASE SYNDROME and NEUROLOGIC TOXICITIES • Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving YESCARTA. Do not administer YESCARTA to patients with active infection or inflammatory disorders.

Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids.

• Neurologic toxicities, including fatal or life-threatening reactions, occurred in patients receiving YESCARTA, including concurrently with CRS or after CRS resolution. Monitor for neurologic toxicities after treatment with YESCARTA. Provide supportive care and/or corticosteroids as needed.

• YESCARTA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the YESCARTA and TECARTUS REMS Program.

INDICATIONS AND USAGE YESCARTA is a CD19-directed genetically modified autologous T cell immunotherapy indicated for the treatment of: • Adult patients with large B-cell lymphoma that is refractory to first-line chemoimmunotherapy or that relapses within 12 months of first-line chemoimmunotherapy.

• Adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, primary mediastinal large B-cell lymphoma, high grade B-cell lymphoma, and DLBCL arising from follicular lymphoma.

Limitations of Use: YESCARTA is not indicated for the treatment of patients with primary central nervous system lymphoma.

DOSAGE AND ADMINISTRATION For autologous use only. For intravenous use only.

Dose: Each single infusion bag of YESCARTA contains a suspension of chimeric antigen receptor (CAR)-positive T cells in approximately 68 mL. The target dose is 2 × 106 CAR-positive viable T cells per kg body weight, with a maximum of 2 × 108 CAR-positive viable T cells.

Preparing Patient for YESCARTA Infusion: Confirm availability of YESCARTA prior to starting the lymphodepleting regimen. Pre-treatment: Administer a lymphodepleting chemotherapy regimen of cyclophosphamide 500 mg/m2 intravenously and fludarabine 30 mg/m2 intravenously on the fifth, fourth, and third day before infusion of YESCARTA. Premedication: Administer acetaminophen 650 mg PO and diphenhydramine 12.5 mg intravenously or PO approximately 1 hour before YESCARTA infusion. Consider the use of prophylactic corticosteroid in patients after weighing the potential benefits and risks.

Preparation of YESCARTA for Infusion: Coordinate the timing of YESCARTA thaw and infusion. Confirm the infusion time in advance, and adjust the start time of YESCARTA thaw such that it will be available for infusion when the patient is ready. Confirm patient identity: Prior to YESCARTA preparation, match the patient’s identity with the patient identifiers on the YESCARTA cassette. Do not remove the YESCARTA product bag from the cassette if the information on the patient-specific label does not match the intended patient. Once patient identification is confirmed, remove the YESCARTA product bag from the cassette and check that the patient information on the cassette label matches the bag label. Inspect the product bag for any breaches of container integrity such as breaks or cracks before thawing. If the bag is compromised, follow the local guidelines (or call Kite at 1-844-454-KITE). Place the infusion bag inside a second sterile bag per local guidelines. Thaw YESCARTA at approximately 37°C using either a water bath or dry thaw method until there is no visible ice in the infusion bag. Gently mix the contents of the bag to disperse clumps of cellular material. If visible cell clumps remain continue to gently mix the contents of the bag. Small clumps of cellular material should disperse with gentle manual mixing. Do not wash, spin down, and/or re-suspend YESCARTA in new medium prior to infusion. Once thawed, YESCARTA may be stored at room temperature (20°C to 25°C) for up to 3 hours.

Administration: For autologous use only. Ensure that tocilizumab and emergency equipment are available prior to infusion and during the recovery period. Do NOT use a leukodepleting filter. Central venous access is recommended for the infusion of YESCARTA. Confirm the patient’s identity matches the patient identifiers on the YESCARTA product bag. Prime the tubing with normal saline prior to infusion.

Infuse the entire contents of the YESCARTA bag within 30 minutes by either gravity or a peristaltic pump. YESCARTA is stable at room temperature for up to 3 hours after thaw. Gently agitate the product bag during YESCARTA infusion to prevent cell clumping. After the entire content of the product bag is infused, rinse the tubing with normal saline at the same infusion rate to ensure all product is delivered. YESCARTA contains human blood cells that are genetically modified with replication incompetent retroviral vector. Follow universal precautions and local biosafety guidelines for handling and disposal to avoid potential transmission of infectious diseases.

Monitoring: Administer YESCARTA at a certified healthcare facility. Monitor patients at least daily for 7 days at the certified healthcare facility following infusion for signs and symptoms of CRS and neurologic toxicities. Instruct patients to remain within proximity of the certified healthcare facility for at least 4 weeks following infusion.

YESCARTA and TECARTUS REMS Program: Because of the risk of CRS and neurologic toxicities, YESCARTA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the YESCARTA and TECARTUS REMS Program. The required components of the YESCARTA and TECARTUS REMS Program are: • Healthcare facilities that dispense and administer YESCARTA must be enrolled and comply with the REMS requirements. Certified healthcare facilities must have on-site, immediate access to tocilizumab, and ensure that a minimum of 2 doses of tocilizumab are available for each patient for infusion within 2 hours after YESCARTA infusion, if needed for treatment of CRS. • Certified healthcare facilities must ensure that healthcare providers who prescribe, dispense, or administer YESCARTA are trained about the management of CRS and neurologic toxicities.

Further information is available at www.YescartaTecartusREMS.com or 1-844-454-KITE (5483).

Hypersensitivity Reactions: Allergic reactions may occur with the infusion of YESCARTA. Serious hypersensitivity reactions, including anaphylaxis, may be due to dimethyl sulfoxide (DMSO) or residual gentamicin in YESCARTA. Serious Infections: Severe or life-threatening infections occurred in patients after YESCARTA infusion. Infections (all grades) occurred in 45% of patients with NHL. Grade 3 or higher infections occurred in 17% of patients, including Grade 3 or higher infections with an unspecified pathogen in 12%, bacterial infections in 5%, viral infections in 3%, and fungal infections in 1%. YESCARTA should not be administered to patients with clinically significant active systemic infections. Monitor patients for signs and symptoms of infection before and after YESCARTA infusion and treat appropriately.

Administer prophylactic antimicrobials according to local guidelines.

Febrile neutropenia was observed in 36% of patients with NHL after YESCARTA infusion and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad-spectrum antibiotics, fluids, and other supportive care as medically indicated. In immunosuppressed patients, including those who have received YESCARTA, life-threatening and fatal opportunistic infections including disseminated fungal infections (e.g., candida sepsis and aspergillus infections) and viral reactivation (e.g., human herpes virus-6 [HHV-6] encephalitis and JC virus progressive multifocal leukoencephalopathy [PML]) have been reported. The possibility of HHV-6 encephalitis and PML should be considered in immunosuppressed patients with neurologic events and appropriate diagnostic evaluations should be performed.

Hepatitis B Virus Reactivation: Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, has occurred in patients treated with drugs directed against B cells, including YESCARTA. Perform screening for HBV, HCV, and HIV and management in accordance with clinical guidelines before collection of cells for manufacturing.

Prolonged Cytopenias: Patients may exhibit cytopenias for several weeks following lymphodepleting chemotherapy and YESCARTA infusion. Grade 3 or higher cytopenias not resolved by Day 30 following YESCARTA infusion occurred in 39% of all patients with NHL and included neutropenia (33%), thrombocytopenia (13%), and anemia (8%).

Monitor blood counts after YESCARTA infusion.

Hypogammaglobulinemia: B-cell aplasia and hypogammaglobulinemia can occur in patients receiving treatment with YESCARTA. Hypogammaglobulinemia was reported as an adverse reaction in 14% of all patients with NHL. Monitor immunoglobulin levels after treatment with YESCARTA and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement.

The safety of immunization with live viral vaccines during or following YESCARTA treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during YESCARTA treatment, and until immune recovery following treatment with YESCARTA. Secondary Malignancies: Patients treated with YESCARTA may develop secondary malignancies. Monitor life-long for secondary malignancies. In the event that a secondary malignancy occurs, contact Kite at 1-844-454-KITE (5483) to obtain instructions on patient samples to collect for testing.

Effects on Ability to Drive and Use Machines: Due to the potential for neurologic events, including altered mental status or seizures, patients receiving YESCARTA are at risk for altered or decreased consciousness or coordination in the 8 weeks following YESCARTA infusion. Advise patients to refrain from driving and engaging in hazardous

WARNINGS AND PRECAUTIONS Cytokine Release Syndrome: CRS, including fatal or life-threatening reactions, occurred following treatment with YESCARTA. CRS occurred in 90% (379/422) of patients with non-Hodgkin lymphoma (NHL) receiving YESCARTA, including ≥ Grade 3 (Lee grading system1) CRS in 9%. CRS occurred in 93% (256/276) of patients with large B-cell lymphoma (LBCL), including ≥ Grade 3 CRS in 9%. Among patients with LBCL who died after receiving YESCARTA, four had ongoing CRS events at the time of death. For patients with LBCL in ZUMA-1, the median time to onset of CRS was 2 days following infusion (range: 1 to 12 days) and the median duration of CRS was 7 days (range: 2 to 58 days). For patients with LBCL in ZUMA-7, the median time to onset of CRS was 3 days following infusion (range: 1 to 10 days) and the median duration was 7 days (range: 2 to 43 days).

Key manifestations of CRS (≥ 10%) in all patients combined included fever (85%), hypotension (40%), tachycardia (32%), chills (22%), hypoxia (20%), headache (15%), and fatigue (12%). Serious events that may be associated with CRS include, cardiac arrhythmias (including atrial fibrillation and ventricular tachycardia), renal insufficiency, cardiac failure, respiratory failure, cardiac arrest, capillary leak syndrome, multi-organ failure, and hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS).

The impact of tocilizumab and/or corticosteroids on the incidence and severity of CRS was assessed in two subsequent cohorts of LBCL patients in ZUMA-1. Among patients who received tocilizumab and/or corticosteroids for ongoing Grade 1 events (see CRS Grading and Management Guidance), CRS occurred in 93% (38/41), including 2% (1/41) with Grade 3 CRS; no patients experienced a Grade 4 or 5 event. The median time to onset of CRS was 2 days (range: 1 to 8 days) and the median duration of CRS was 7 days (range: 2 to 16 days).

Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of YESCARTA. Thirty-one of the 39 patients (79%) developed CRS at which point the patients were managed with tocilizumab and/or therapeutic doses of corticosteroids with no patients developing Grade 3 or higher CRS. The median time to onset of CRS was 5 days (range: 1 to 15 days) and the median duration of CRS was 4 days (range: 1 to 10 days). Although there is no known mechanistic explanation, consider the risk and benefits of prophylactic corticosteroids in the context of pre-existing comorbidities for the individual patient and the potential for the risk of Grade 4 and prolonged neurologic toxicities.

Ensure that 2 doses of tocilizumab are available prior to infusion of YESCARTA. Monitor patients at least daily for 7 days at the certified healthcare facility following infusion for signs and symptoms of CRS. Monitor patients for signs or symptoms of CRS for 4 weeks after infusion. Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time. At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids as indicated.

Neurologic Toxicities: Neurologic toxicities (including ICANS) that were fatal or life-threatening occurred following treatment with YESCARTA. Neurologic toxicities occurred in 78% (330/422) of patients with NHL receiving YESCARTA, including ≥ Grade 3 cases in 25%.

Neurologic toxicities occurred in 87% (94/108) of patients with LBCL in ZUMA-1, including ≥ Grade 3 cases in 31% and in 74% (124/168) of patients in ZUMA-7 including ≥ Grade 3 cases in 25%. The median time to onset was 4 days (range: 1 to 43 days) and the median duration was 17 days in patients with LBCL in ZUMA-1.

The median time to onset for neurologic toxicity was 5 days (range: 1 to 133 days) and median duration was 15 days in patients with LBCL in ZUMA-7. Ninety-eight percent of all neurologic toxicities in patients with LBCL occurred within the first 8 weeks of YESCARTA infusion. Neurologic toxicities occurred within the first 7 days of YESCARTA infusion in 87% of affected patients with LBCL. The most common neurologic toxicities (≥ 10%) in all patients combined included encephalopathy (50%), headache (43%), tremor (29%), dizziness (21%), aphasia (17%), delirium (15%), and insomnia (10%). Prolonged encephalopathy lasting up to 173 days was noted. Serious events including aphasia, leukoencephalopathy, dysarthria, lethargy, and seizures occurred with YESCARTA. Fatal and serious cases of cerebral edema and encephalopathy, including late-onset encephalopathy, have occurred in patients treated with YESCARTA.

The impact of tocilizumab and/or corticosteroids on the incidence and severity of neurologic toxicities was assessed in two subsequent cohorts of LBCL patients in ZUMA-1. Among patients who received corticosteroids at the onset of Grade 1 toxicities (see Neurologic Toxicity/ICANS Grading and Management Guidance), neurologic toxicities occurred in 78% (32/41) and 20% (8/41) had Grade 3 neurologic toxicities; no patients experienced a Grade 4 or 5 event. The median time to onset of neurologic toxicities was 6 days (range: 1 to 93 days) with a median duration of 8 days (range: 1 to 144 days).

Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of YESCARTA. Of these 39 patients, 85% (33/39) developed neurologic toxicities; 8% (3/39) developed Grade 3 and 5% (2/39) developed Grade 4 neurologic toxicities. The median time to onset of neurological toxicities was 6 days (range: 1 to 274 days) with a median duration of 12 days (range: 1 to 107 days). Prophylactic corticosteroids for management of CRS and neurologic toxicities may result in higher grade of neurologic toxicities or prolongation of neurologic toxicities, delay the onset and decrease the duration of CRS.

Adverse Reactions in ≥ 10% of Patients Treated with YESCARTA in ZUMA-7 (CONT’D)

Clinical Trials Experience: Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Relapsed or Refractory Large B-cell Lymphoma ZUMA-7: The safety of YESCARTA was evaluated in ZUMA-7, a randomized, open-label, multicenter study in which patients with primary refractory LBCL or first relapse of LBCL received YESCARTA (N = 168) or standard therapy (N = 168). Patients had not yet received treatment for relapsed or refractory lymphoma and were potential candidates for autologous HSCT. The trial excluded patients who were not deemed candidates for transplant or who had a history of central nervous system (CNS) disorders (such as seizures or cerebrovascular ischemia), serious or uncontrolled infection, or autoimmune disease requiring systemic immunosuppression. The study required ANC ≥ 1000/mm3, platelet count ≥ 75,000/mm3, creatinine clearance ≥ 60 mL/min, AST/ALT ≤ 2.5 x ULN, and total bilirubin ≤ 1.5 mg/dL. The median age of the YESCARTA-treated safety population was 59 years (range: 21 to 80 years); 62% were male. The baseline Eastern Cooperative Oncology Group (ECOG) performance status was 0 in 54% of patients and 1 in 46%.

The most common non-laboratory adverse reactions to YESCARTA (incidence ≥ 20%) included fever, CRS, fatigue, hypotension, encephalopathy, tachycardia, diarrhea, headache, musculoskeletal pain, nausea, febrile neutropenia, chills, cough, infection with unspecified pathogen, dizziness, tremor, decreased appetite, edema, hypoxia, abdominal pain, aphasia, constipation, and vomiting. Serious adverse reactions occurred in 50% of patients. The most common serious adverse reactions (> 5%) included CRS, fever, encephalopathy, hypotension, infection with unspecified pathogen, and pneumonia. Fatal adverse reactions occurred in 2% of patients.

The most common (≥ 10%) Grade 3 or higher non-laboratory adverse reactions included febrile neutropenia, encephalopathy, and hypotension.

USE IN SPECIFIC POPULATIONS Pregnancy: Risk Summary: There are no available data with YESCARTA use in pregnant women. No animal reproductive and developmental toxicity studies have been conducted with YESCARTA to assess whether it can cause fetal harm when administered to a pregnant woman. It is not known if YESCARTA has the potential to be transferred to the fetus. Based on the mechanism of action, if the transduced cells cross the placenta, they may cause fetal toxicity, including B-cell lymphocytopenia. Therefore, YESCARTA is not recommended for women who are pregnant, and pregnancy after YESCARTA infusion should be discussed with the treating physician. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% - 4% and 15% - 20%, respectively.

Lactation: Risk Summary: There is no information regarding the presence of YESCARTA in human milk, the effect on the breastfed infant, and the effects on milk production.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for YESCARTA and any potential adverse effects on the breastfed infant from YESCARTA or from the underlying maternal condition.

Females and Males of Reproductive Potential: Pregnancy Testing: Pregnancy status of females with reproductive potential should be verified. Sexually active females of reproductive potential should have a pregnancy test prior to starting treatment with YESCARTA. Contraception: See the prescribing information for fludarabine and cyclophosphamide for information on the need for effective contraception in patients who receive the lymphodepleting chemotherapy. There are insufficient exposure data to provide a recommendation concerning duration of contraception following treatment with YESCARTA. Infertility: There are no data on the effect of YESCARTA on fertility.

Pediatric Use: The safety and efficacy of YESCARTA have not been established in pediatric patients.

Geriatric Use: Of the 422 patients with NHL who received YESCARTA in clinical trials, 127 patients (30%) were 65 years of age and older. No clinically important differences in safety or effectiveness were observed between patients aged 65 years and older and younger patients.

The safety and efficacy of YESCARTA was evaluated in two subsequent cohorts of LBCL patients. The first subsequent, open label, safety management cohort in ZUMA-1 evaluated the safety and efficacy of YESCARTA with the use of tocilizumab and/or corticosteroid and prophylactic levetiracetam (750 mg PO or IV twice daily) for Grade 1 CRS or neurologic events. A total of 46 patients with relapsed or refractory LBCL were enrolled and 41 patients were treated with YESCARTA. Of the remaining 5 patients who were not treated, 2 patients died prior to receiving YESCARTA and 3 patients were ineligible due to disease progression. Twenty-eight patients (68%) treated with YESCARTA received bridging therapy between leukapheresis and lymphodepleting chemotherapy. Thirty-two patients (78%) treated with YESCARTA received tocilizumab and/or corticosteroid for CRS and/or neurologic events. Fifteen of 36 with Grade 1 CRS and 21 of 24 patients with Grade 2 CRS received tocilizumab and/or corticosteroids.

Among patients who received treatment for Grade 1 or Grade 2 CRS, most patients (13 of 15 and 19 of 21 patients, respectively) received both tocilizumab and corticosteroids. Most patients received 1 or 2 doses of each drug. Ten of 27 patients with Grade 1 and 7 of 15 patients with Grade 2 neurologic events received corticosteroids alone or in combination with tocilizumab.

The second subsequent, open label, safety management cohort in ZUMA-1 evaluated the safety and efficacy of YESCARTA with the use of prophylactic corticosteroids (oral dexamethasone 10 mg once daily for 3 days, starting prior to YESCARTA infusion on Day 0) and prophylactic levetiracetam (750 mg PO or IV).

Immunogenicity: YESCARTA has the potential to induce anti-product antibodies.

The immunogenicity of YESCARTA has been evaluated using an enzyme-linked immunosorbent assay (ELISA) for the detection of binding antibodies against FMC63, the originating antibody of the anti-CD19 CAR. Eleven patients (4%) tested positive for pre-dose anti-FMC63 antibodies at baseline in ZUMA-7 and ZUMA-1, and one patient (1%) who had a negative test result at baseline had a positive test result post administration of YESCARTA in the screening ELISA in ZUMA-7. Results of a confirmatory cell-based assay, leveraging a properly folded and expressed extracellular portion of the CAR (ScFv, hinge and linker) demonstrated that all patients treated with YESCARTA that had a positive result in the screening ELISA were antibody negative at all time points tested. There is no evidence that the kinetics of initial expansion and persistence of YESCARTA, or the safety or effectiveness of YESCARTA, was altered in these patients.

Postmarketing Experience: The following adverse reactions have been identified during post-approval use of YESCARTA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Nervous System Disorders: Spinal cord edema, myelitis, quadriplegia, and dysphagia.

Hereditary Transthyretin Amyloidosis (hATTR): Management Update Data integration of pharmacy and medical benefit claims will allow payers to determine the total cost of care and promote steps that will facilitate treatment decisions.

The nomenclature has changed with familial forms of transthyretin amyloidosis (ATTR). Previously known as familial amyloid polyneuropathy (FAP) or familial amyloid cardiomyopathy (FAC), it is now called hereditary ATTR (hATTR).1 hATTR is a rare, heterogenous disease resulting from a deposition of soluble and insoluble amyloid fibrils or aggregates in the beta sheets of various organs, including peripheral nerves, heart, kidney, and ocular vitreous.2, 3 Amyloid deposits result when autosomal-dominant mutation in the transthyretin (TTR) gene leads to TTR protein misfolds. The wild-type transthyretin-mediated amyloidosis (ATTRwt), previously known as senile cardiac amyloidosis, is caused by an instability of the natural TTR protein, which is predominantly made in the liver and transports thyroxine and retinol (vitamin A) throughout the body.2

Simone Ndujiuba, Pharm.D., BCOP Director, Clinical Strategy and Innovation, Oncology Magellan Rx Management

Due to signs and symptoms that overlap with a variety of other conditions, hATTR is not readily diagnosed, which makes it difficult to quantify the number of patients currently living with hATTR. Based on current data, it is estimated that 10,000 to 15,000 people live with hATTR in the U.S., with approximately 50,000 individuals with varying phenotypic presentation of the disease worldwide.4. 5 Over the years, advancements in imaging and increased genetic testing have enhanced timely diagnosis. As a result, the number of patients diagnosed with hATTR is projected to increase.6 More than 130 TTR variants have been identified, many with regional clusters around the world. The V30M mutation accounts for an estimated 50% of the world’s variants and is the predominant form in endemic regions. The ATTR V30M is found in parts of Europe and Japan; ATTR V122I is identified in 3-4% of African Americans; and ATTR T60A, the most identified variant in the United Kingdom, has higher rates in people of Irish descent.6

The therapeutic goal for hATTR is reduction in symptom severity and establishment of a long-term treatment plan.

fraction. Clinical presentation includes unexplained left ventricular hypertrophy, which results in restrictive cardiomyopathy, heart failure, atrial fibrillation, and conduction abnormalities. Predominant cardiomyopathy with heart failure routinely shows preserved ejection in men older than 60.6 The estimated survival for patients with neurologic dominant hATTR is 5 to 15 years; this estimate is reduced 2.5 to 4 years for patients with cardiac-dominant disease.

Overall, if hATTR is left untreated, death may occur within 10 years.7

Treatment hATTR primarily presents as a somatic and autonomic nervous system impairment, polyneuropathy (hATTR-PN) seen in early adulthood, and cardiomyopathy (hATTR-CM) seen later in life. If the TTR gene sequence does not have a mutation, it is designated as a wild-type (ATTRwt) and leads to cardiomyopathy. Most patients show signs of a combination of peripheral nervous system and cardiac impairment.

By their second decade of life, most patients present with initial neurologic symptoms. As patients near their third and fifth decades, hATTR-PN progresses with signs and symptoms that include sensorymotor polyneuropathy with autonomic involvement, postural hypotension, and bladder and erectile dysfunction, to name a few. hATTR-CM commonly occurs by age 60 or older, with a greater incidence in men than women.4 Hypertrophic cardiomyopathy, even if usually latent, is identifiable in at least 50% of the patients.2 Patients with variants such as Val122Ile, Leu111Met, Ile68Leu, and ATTRwt develop cardiac impairment with preserved ejection

36 | Magellan Rx Report | Fall 2022

The therapeutic goal for hATTR is reduction in symptom severity and establishment of a long-term treatment plan. In the 1990s, liver transplant to eliminate amyloid protein production was the preferred treatment of choice. However, transplant led to cardiovascular complications, which led to death in 22% of patients and a 20-year survival rate of 55.3%. With increased diagnosis and treatment advancements, therapeutic options have expanded.2 Currently, medication is indicated for treatment of polyneuropathy or cardiomyopathy but not for all types of hATTR. Reduction in cardiovascular mortality and cardiovascularrelated hospitalization is a key goal, so the FDA approval of two oral selective stabilizers of the TTR tetramer, Vyndaqel® (tafamidis meglumine) and Vyndamax™ (tafamidis), with indications for the treatment of the cardiomyopathy of wild-type or hATTR amyloidosis, will help to accomplish this goal.8-9 hATTR-PN parenteral therapy

options that inhibit TTR hepatic production, such as Onpattro® (patisiran), Tegsedi® (inotersen), and Amvuttra™ (vutrisiran), have also been FDA-approved. Multiple agents are in development to target various stages of ATTR pathogenesis.2, 10-12

The complexity of this disease and its intersection with other conditions creates gaps AMVUTTRA™ (vutrisiran) In June 2022, the Food and Drug Administration (FDA) approved in payers’ ability to identify Amvuttra (vutrisiran) for polyneuropathy of hereditary affected patients. transthyretin-mediated amyloidosis in adults. Vutrisiran is supplied as a single-dose prefilled syringe administered by a healthcare professional once every three months (for four doses per year). In the HELIOS-A phase 3 study, vutrisiran (n=122) was compared to active therapy infusion (external placebo) patisiran (N=42).15 The primary end point was change from baseline in neuropathy impairment using the modified Neuropathy Impairment Score +7 (mNIS+7) versus external placebo at month 9. The study was an intention-to-treat, with patients receiving one or more doses of vutrisiran or placebo. At nine months, vutrisiran quickly attained a decrease in serum TTR level, demonstrating a significant improvement in multiple end points when evaluated against the external placebo. The primary end point was achieved: Vutrisiran significantly improved mNIS+7 versus external placebo (LS mean [±SE] change from baseline: −2.2±1.4 [vutrisiran]; +14.8±2.0 [placebo]; difference −17.0; p=3.5×10−12). Vutrisiran also significantly improved quality of life, gait speed, nutritional status, and disability compared to the external placebo. Vutrisiran was well tolerated with mild to moderate adverse effects and no drug discontinuation or death.13

Payment Management Strategies In 2020, a retrospective trial analyzed claims data for newly diagnosed hATTR. The study determined that the annual mean total cost to treat each patient was $64,066.14 Inpatient care was the greatest expense ($34,461), with outpatient ($23,853) and pharmacy ($5,752) adding to overall expenditure. The highest utilization occurred during the first quarter post-diagnosis, then decreased in following quarters. Insurance type varied; preferred provider organization/point of service plans (65.9%) were most

utilized, followed by comprehensive (12.4%) and consumerdirected health plan/high-deductible health plans (11.4%).14 In a recent meeting of healthcare decision-makers, a group of payers discussed their role in supporting the identification, management, and consideration of medical and pharmacy benefits for patients with rare disease, particularly hATTR.15 The complexity of this disease and its intersection with other conditions creates gaps in payers’ ability to identify affected patients. With the breadth of complications associated with this rare disease, payers recognized the need for collaboration with case management, health plans, and health systems to create a patient-centered program.15 When medication coverage was addressed, payers agreed that identification of actionable mutations makes it easier to justify high-cost medications.15 In addition, test results help to determine if family members also require screening and early intervention. Ultimately, the payers preferred medications processed through the pharmacy benefit.

Traditionally, pharmacy claims decrease drug cost variability. With medical claims, the risk for variable cost increases, especially as costs associated with specialists and centers of excellence come into play. Data integration of pharmacy and medical benefit claims will allow payers to determine the total cost of care and promote steps that will facilitate treatment decisions.15 Three phase 3 trials, one for vutrisiran in hATTR-CM and two for eplontersen on cardiomyopathy and polyneuropathy in hATTR, demonstrate continued treatment advancements for this rare disease.16

Product Spotlight: Ivosidenib (Tibsovo®) A new option for treatment of acute myeloid leukemia.

In May 2022, the U.S. Food and Drug Administration (FDA) approved ivosidenib (Tibsovo®, Servier Pharmaceuticals) in combination with azacitidine for newly diagnosed acute myeloid leukemia (AML) with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation, as detected by an FDA-approved test in adults 75 years and older or who have comorbidities that preclude the use of intensive induction chemotherapy.1 Previously, in 2021, the FDA approved ivosidenib for adult patients with previously treated, locally advanced, or metastatic cholangiocarcinoma with an IDH1 mutation as detected by an FDA-approved test.2

Acute Myeloid Leukemia AML is a rare cancer of the blood and bone marrow that accounts for only 1% of new cancer cases.3 The median age of diagnosis is 68 years, and about 70% of patients do not survive past five years of diagnosis.3, 4 The most common treatment for AML is chemotherapy for induction (cytarabine, daunorubicin) and consolidation (high-dose cytarabine).5 For patients with newly diagnosed AML, the National Comprehensive Cancer Network (NCCN) recommends clinical trials, targeted treatments, chemotherapy, hypomethylating agents, and supportive care as treatment options.6 Notably, elderly patients may not be appropriate candidates for intensive chemotherapy, considering associated toxicities such as myelosuppression, neutropenia, and higher risk of infection.7 Relapsed/refractory (R/R) AML is particularly challenging to manage with relatively few options; NCCN recommends aggressive chemotherapy for suitable patients, but these regimens are associated with substantial toxicities.6, 8, 9 In patients with R/R AML, NCCN also recommends less aggressive therapies or targeted therapies, which can be associated with toxicities such as gastrointestinal toxicity, rash, and myelosuppression.6, 8, 9

40 | Magellan Rx Report | Fall 2022

The IDH1 mutation is a driver mutation found in 6-10% of both newly diagnosed and R/R AML populations that leads to lack of cellular differentiation in AML and is associated with negative prognosis.10-13 Both the NCCN and the American Society of Hematology/College of American Pathologists recommend testing for mutations, including IDH1, in patients with AML.6, 14

Ivosidenib in Newly Diagnosed AML FDA approval of ivosidenib for AML was based on a randomized, multicenter, double-blind, placebo-controlled study of 146 patients with newly diagnosed AML with an IDH1 mutation meeting one of the following criteria: 75 years of age or older, baseline Eastern Cooperative Oncology Group performance status of 2, severe cardiac or pulmonary disease, hepatic impairment with bilirubin greater than 1.5 times the upper limit of normal, creatinine clearance less than 45 mL/min, or other comorbidity.15 Patients were randomized to receive ivosidenib 500 mg or placebo daily by oral administration on days 1 through 28 in combination with intravenous or subcutaneous azacitidine 75mg/m2/day on days 1 through 8 or days 1 through 5 and 8 through 9 of each 28-day cycle until disease progression, unacceptable toxicity, or hematopoietic stem cell transplantation.15 The primary end point was event-free survival (time from randomization until treatment failure, relapse from remission, or death from any cause).15 Eventfree survival at 12 months had an estimated probability of 37% in

the ivosidenib and azacitidine group and 12% in the placebo and azacitidine group.15 Patients treated with ivosidenib and azacitidine had a median overall survival of 24 months compared to 7.9 months for patients treated with placebo and azacitidine.15 Febrile neutropenia occurred at a higher incidence in the placebo group than in the ivosidenib group (34% versus 28%, respectively). The incidence of infection of any grade was 28% with ivosidenib and azacitidine and 49% with placebo and azacitidine.15 NCCN Guidelines recommend ivosidenib as a targeted therapy for select patients with newly diagnosed R/R AML with an IDH1 mutation, specifically adult patients with newly diagnosed AML who are 60 years of age or older or who have comorbidities that preclude use of intensive induction chemotherapy or adult patients with R/R AML.6

Cholangiocarcinoma Cholangiocarcinomas are a heterogenous group of biliary tract cancers, classified as intrahepatic or extrahepatic, in which tumors develop from the epithelial lining of the biliary tree. Around 8,000 adults in the U.S. are diagnosed with cholangiocarcinoma each year, with extrahepatic cases accounting for 80% of all diagnosed and intrahepatic cases accounting for the remaining 20%.16, 19 Average age at diagnosis is 70 and 72 years old for intrahepatic and extrahepatic cholangiocarcinoma, respectively.19

NCCN Guidelines recommend ivosidenib as a targeted therapy for select patients with newly diagnosed R/R AML with an IDH1 mutation, specifically adult patients with newly diagnosed AML who are 60 years of age or older or who have comorbidities that preclude use of intensive induction chemotherapy or adult patients with R/R AML. Typically, individuals have advanced-stage disease at presentation and diagnosis; thus, the five-year survival rate for these patients is low, about 10%.16-18, 20 For patients with unresectable or metastatic cholangiocarcinoma, first-line treatment includes gemcitabine and cisplatin with or without durvalumab.21 There is no clear standard of care for subsequent lines.22-25 The median survival time for patients with advanced-stage cholangiocarcinoma on chemotherapy is less than one year.21, 25 The NCCN recommends molecular testing of unresectable and metastatic tumors, given emerging evidence regarding actionable targets for treatment of cholangiocarcinoma.26

IDH1 mutations are an emerging molecular target for treatment and can be identified using molecular testing.18, 21, 27

Ivosidenib in Cholangiocarcinoma A randomized 2:1, multicenter, double-blind, placebo-controlled clinical trial evaluated efficacy of ivosidenib in treating cholangiocarcinoma.28 The trial consisted of 185 adults with locally advanced or metastatic cholangiocarcinoma with an IDH1 mutation; participants must have had disease progression following at least one but no more than two prior regimens, including at least one gemcitabine- or 5-flurouracil-containing regimen.28 Patients were randomized, receiving either ivosidenib 500 mg orally once daily or matched placebo until disease progression or unacceptable toxicity, with those in the placebo arm allowed to cross over to ivosidenib after documentation of radiographic disease progression.28 The primary end point of the trial was progression-free survival.28 Patients receiving ivosidenib showed a statistically significant improvement in progression-free survival compared to patients receiving placebo (2.7 months versus 1.4 months, respectively).28 Median overall survival was 10.3 months with ivosidenib versus 7.5 months with placebo.29 When adjusted for the crossover, median overall survival with placebo was 5.1 months. The EORTC Core Quality of Life questionnaire C30 and BIL21 assessed quality of life changes from baseline as well as the PGI-C anchor questions for physical functioning, pain, and appetite loss.29 Patients in the ivosidenib group had preserved physical function, while those in the placebo group experienced a decline from baseline.29 Adverse reactions reported in more than 15% of patients included fatigue, nausea, abdominal pain, diarrhea, cough, decreased appetite, ascites, vomiting, anemia, and rash.28 The NCCN Guidelines recommend ivosidenib as a subsequent-line treatment option for unresectable or metastatic cholangiocarcinoma in patients with an IDH1 mutation following disease progression.26

BIOLOGIC OPTIONS IN THE MARKETPLACE ARE EVOLVING Unbranded Biologics Are Another Option for Your Formulary AN UNBRANDED BIOLOGIC IS NOT A BIOSIMILAR

Brand-Name Biologic1

Unbranded Biologic2

Biosimilar1,3

Approved based on a full complement of safety and effectiveness data

The same as the brand-name biologic

Highly similar to brand-name biologic* with no clinically meaningful differences

Produced through biotechnology in a living system (ie, a “cell line”)

Produced using the same cell line as the brand-name biologic

Produced using a different cell line

*“Brand-name biologic” refers to the reference biologic.

AN UNBRANDED BIOLOGIC IS 2 : • An approved brand-name biologic being marketed under its approved biologics license† without the brand name • Considered by the FDA to be the same product as the brand-name biologic under the same biologics license‡ • The same in strength, dosage form, route of administration, and presentation as the brand-name biologic †Biologics are FDA approved through a biologics license application (BLA). ‡No difference in strength, dosage form and route of administration, and presentation vs its approved brand-name biologic.
