A NOTE FROM OUR CEO

Dear Managed Care Colleagues, Welcome to our spring 2023 issue of the Magellan Rx Report!

Since the release of our last edition in the fall, Magellan Rx has joined forces with Prime Therapeutics to usher in the next chapter of our company's evolution. This transformational opportunity enables us to build upon our thought leadership expertise in managed care pharmacy to create a brighter future for our industry and deliver even more value to those we serve. As a result, we will continue to keep our readers informed on the latest managed care trends and treatment updates, shining a bright light on insights and opportunities for the future.

In this edition of the report, we've captured this year's momentum with the D appro al of e no el drugs and an expansive pipeline full of promising new agents across chronic conditions for the remainder of 2023. Our cover story (page 26) focuses on innovative CAR-T therapy. We review the landscape of CAR-T with a comprehensive review of the currently approved and available CAR-T therapies, as well as highlighting recent CAR-T approvals. The article also outlines the pipeline in this category as well as potential payer management strategies.

Another article (page 6) focuses on the imminent impact of adalimumab biosimilars entering the mar et. s the rst adalimumab biosimilar launched in January, with more anticipated launches throughout 2023, this space will see a

major shift in management and reimbursement for payers and manufacturers alike.

In our hemophilia article (page 10), we highlight the recent approvals of gene therapies in this category and the pipeline of gene therapies on the horizon for hemophilia. We also discuss how these innovative treatment options will impact payers, making hemophilia a high-priority management category.

Other topics in this issue include a dive into Alzheimer’s disease and recent advances (page 15), a brief rare disease update and pipeline (page 22), and an oncology update on current developments in breast cancer treatment (page 32). As always, the issue is rounded out with our pipeline update (page 38) and managed care newsstand (page 4).

MANAGED CARE NEWSSTAND Senate Judiciary Committee Advances Drug Patent Reform, FDA-PTO Bills to Floor The Senate Judiciary Committee voted to advance a handful of bipartisan bills that promote drug competition and biosimilar market entry: The Interagency Patent Coordination and Improvement Act, which passed the committee in summer 2022, would establish a task force that coordinates e orts and shares information on drug patent decision making between the United States Patent and Trademark O ce U TO and the U. . ood Drug Administration (FDA), including information on patent-application evaluations, training, and FDA approvals.

The Stop STALLING Act would penalize brand drug ma ers for ling sham citi en petitions with the FDA that interfere with the approval of competing generics and biosimilars.

The Preserve Access to Affordable Generics and Biosimilars Act aims to limit the use of “pay-for-delay” agreements by making them presumptively anticompetitive, illegal, and increasingly di cult for drug ma ers to justify in court.

The Prescription Pricing for the People Act, which was reintroduced earlier this month, would require the Federal Trade Commission (FTC) to examine price

consolidations and anti-competitive practices within the entire pharmaceutical supply chain that may impact the cost of prescription drugs for consumers.

The Affordable Prescriptions for Patients Act, which passed the Senate Finance Committee in 2020, aims to stop abuse of patents via product hopping and other tactics used by brand-name drug makers to prevent generics and biosimilars from entering the market.

CMS Drug Price Negotiation Timeline 2026 The Inflation Reduction ct IR , signed into law in August 2022, included key healthcare provisions. One of these major provisions regarded allowing Medicare to negotiate drug prices. Centers for Medicare edicaid er ices released a Drug Price Negotiation Timeline for 2026, which outlines initial actions for the program.

According to the timeline, CMS will publish the maximum fair prices for drugs selected for negotiation for 2026 with these prices going into e ect on an. , 202 .

Provision in the FY23 Omnibus Spending Bill On Dec. 29, President Joe Biden signed the Consolidated Appropriations Act, 2023 into law, including . trillion in scal year (FY) 2023 discretionary government funding across all 12 annual spending bills. This bill included a number of other healthcare provisions, which touch on the following: CBO Access to DIR Data: Authorizes the ongressional udget O ce O to access prescription drug payment data including rebate and Direct and Indirect Remuneration (DIR) data under Medicare Part D.

CHIP: Extends the Children’s Health Insurance Program (CHIP) until 2029; children on CHIP get one year of continuous eligibility.

Medicaid: Allows states to begin reevaluating who is still eligible for Medicaid beginning in April, while requiring states to attempt to contract bene ciaries before disenrolling them from the program; gradually phases out 6.2% increased pandemic Medicaid funding.

COVID-19 EUA Coverage: No additional COVID-19 funding, but it allows Medicare Part D plans to cover products for COVID-19 approved under an emergency use authorization (EUA) through 2024.

Mental Health Parity: Requires selffunded, nonfederal government health plans to comply with mental health parity requirements beginning six months after the date of enactment or longer, contingent on the terms of the plan agreement.

Interchangeable Biosimilars lari es the FDA’s authority to tentatively approve a subsequent interchangeable biosimilar while a rst interchangeable product’s exclusivity period is pending. Multiple interchangeable biosimilars can share a period of rst interchangeable exclusi ity if they are approved the same day.

FDA Post-Approval Studies: Adds to requirements for post-approval studies for drugs approved under accelerated approval, including targets, milestones, and dates for study completion — and clari es the D ’s authority to withdraw products where sponsors fail to conduct the studies.

FDA: Requires the FDA to make timely therapeutic equivalence evaluation for follow-on drugs approved through the 505(b)(2) pathway — a pathway in

between novel new drugs and generics — that have similar formulations as other approved pathways, and it facilitates the availability of lower-cost drugs available for automatic substitution in pharmacies.

MTM for Opioids: Eliminates a current requirement for medication therapy management (MTM) for opioid addiction that those registered to dispensecontrolled substances also apply for a separate Drug Enforcement Administration (DEA) waiver to dispense buprenorphine.

Generic Drug Labeling: Provides that a generic drug is eligible for approval despite di erences in proposed labeling.

CMS Draft Guidance for Medicare Prescription Drug Inflation Rebate Program On Feb. 8, the Department of Health and Human Services (HHS) released an initial guidance for the Medicare Prescription Drug Inflation Rebate rogram. The program requires pharmaceutical manufacturers to pay a rebate if the prices of certain drugs are increased at a rate faster than the rate of inflation. edicare art prescription drug inflation rebates were established for single-source drugs and biologics with faster-increasing prices than the rate of inflation and pro ides lower art bene ciary cost sharing on those drugs. The guidance outlines how CMS will calculate drug inflation rebates in edicare art and D as required under the IRA.

PHE Will Expire on May 11 On Feb. 9, HHS released a COVID-19 Public Health Emergency (PHE) Transition Roadmap noting that the PHE will end on May 11. The roadmap includes an outline of what program and flexibilities will and will not be a ected.

Senate Hearing on Transparency and Accountability for PBMs The Senate Committee on Commerce, Science, and Transportation held a hearing titled “Bringing Transparency and ccountability to harmacy ene t Managers” in February to focus on the role of PBMs in how Americans access their medications as well as the operations of PBMs. The hearing addressed how the harmacy ene t anager Transparency Act will bring transparency into PBM business practices.

Due to expected launches and uptake in biosimilar utilization, biosimilar spending is expected to reach $129 billion by 2027.

Proposed PBM Bills in the New Congress The PBM Accountability Act has been reintroduced as S. 127. Sen. Maria Cantwell (D-WA) chairs the committee and is eager to move forward with the bill. Last year, the bill passed out of the committee by a wide bipartisan margin but ne er made it to the enate floor due to other priorities. The bill would regulate PBMs through the FTC.

New IQVIA Report Notes Increase in Biosimilar Spending in Next Five Years According to the new “IQVIA Biosimilars in the United States 2023-2027” report, spending on biosimilars in the U.S. is expected to increase substantially o er the next e years. Due to expected launches and uptake in biosimilar utilization, biosimilar spending is expected to reach $129 billion by 2027.

Savings associated with biosimilars are expected to increase by $180 billion in the same timeframe. In the pre ious e years, the U.S. biologics market has grown by 12.5% annually. Currently available and launched biosimilars account for 24% of the competitive volume.

IRA: CMS Implementation Timeline CMS released an IRA Implementation Timeline, outlining when changes brought by pro isions of the IR will go into e ect.

Some notable dates in 2023 include: April 1: Individuals with traditional Medicare may pay a lower coinsurance for some Part B drugs if the drug’s price increased faster than the rate of inflation in a benchmark quarter.

July 1: Individuals with traditional Medicare who take insulin through a traditional pump will not pay more than $35 for a month’s supply of insulin.

Sept. 1: CMS will announce by this date the rst 0 edicare art D drugs selected for the Drug Price Negotiation Program.

Oct. 1: Most adults with coverage from Medicaid and CHIP will be guaranteed coverage of vaccines recommended by the Advisory Committee Immunization Practices at no cost to them.

Adalimumab Biosimilars: Launch and Payer Management Payers should focus on assessing reimbursement agreements to ensure they are best managing this category, ensuring patients have access to appropriate therapies and both patients and payers are bene ting from cost sa ings.

Adalimumab (HUMIRA® has been a highly pro table and utili ed drug in the U. . mar et, generating more than $20.7 billion in sales in 2021 and ranking second on a list of the top-selling drugs of all time in 2018.1 Through 2023 and 2024, an anticipated 14 or more adalimumab biosimilars may launch.

At least seven adalimumab biosimilars will likely launch in 2023, which will include both the original formulation (50 mg/mL) and new high-concentration formulation (100 mg/mL) products.1 The U.S. Food Drug dministration D has appro ed se en biosimilars for adalimumab so far, with se eral more being reviewed and investigated.

Martin Burruano, R.Ph. Vice President, Pharmacy Services Independent Health

Upon launch, the adalimumab biosimilars will impact the treatment landscape across several indications, including rheumatoid arthritis (RA), Crohn’s disease (CD), ulcerative colitis (UC), plaque psoriasis, psoriatic arthritis, and more. dalimumab-atto EVIT was the rst adalimumab biosimilar to launch in the U. . on an. , 202 it was also the rst appro ed in eptember 20 .1, 2 In early uly 202 , e additional adalimumab biosimilars are set to launch: adalimumab-adbm (Cyltezo®, Boehringer Ingelheim), adalimumab-bwwd (HADLIMA®, Organon), adalimumab-fkjp (Hulio®, Mylan), adalimumab-adaz (HYRIMOZ®, Sandoz), and adalimumab-aqvh (YUSIMRY™, Coherus BioSciences).1, 3 The FDA is currently reviewing biologics license applications (BLAs) for three biosimilars and a highconcentration version of one biosimilar, which has already been approved for low-concentration formulation.

Interchangeability

Different Formulations

The FDA designation interchangeable allows biosimilar products to be substituted for the reference product at the pharmacy level, without requiring provider permission.1 The interchangeability designation creates an ease of access to biosimilars, as the burden of pharmacists obtaining approval is removed. Cyltezo® is the only adalimumab biosimilar that is currently deemed interchangeable, although manufacturers are seeking the designation for some others currently approved or under review.1

Only the reference product and HADLIMA™ currently have highconcentration formulations approved by the FDA. The vast majority of reference adalimumab prescriptions in the U.S. market, more than 80%, are for the high-concentration solution. High-concentration formulations of adalimumab reduce the number of doses required for e ecti e treatment, compared to low-concentration formulations.1

Notably, the interchangeability designation does not indicate superiority in safety or e cacy for some biosimilars o er others, just that studies assessing patients switching between the reference and biosimilar have been conducted and completed.1 While generally interchangeable biosimilars can be dispensed in place of a reference product, some states have made restrictions as providers can request dispensing of the reference drug rather than any biosimilar regardless of interchangeability.4

Citrate-free formulations may reduce injection site pain and allow for the use of a smaller needle during treatment administration. Of the biosimilar products approved or under FDA review, all have citratefree options, except for HYRIMOZ and low-concentration HADLIMA™.1

Impact on Treatment & Management Landscape The launch of adalimumab biosimilars will create a burden and opportunity for all stakeholders. Providers will face the challenge

ADALIMUMAB BIOSIMILARS | Continued

The key to uptake in biosimilar utilization will be stakeholder education, especially for patients. of serving as a liaison between patients and payers, weighing payer preferences and management strategies against the needs and appropriate management of the patient.1 Rheumatologists or other providers treating patients using adalimumab are likely already familiar with biosimilars, as biosimilars for infliximab and rituximab ha e been a ailable in the treatment landscape.5 Providers’ experience and familiarity with biosimilars will undoubtedly impact their comfortability in using biosimilars when starting new patients on adalimumab as well as switching patients from the reference to biosimilars.5 In many cases, when patients respond well to the reference drug, pro iders may feel more con dent switching them to an interchangeable biosimilar.4 The key to uptake in biosimilar utilization will be stakeholder education, especially for patients. Payers and providers alike can provide educational materials and updates to patients so they are more comfortable and con dent in the transition to biosimilar adalimumab, where that decision is deemed appropriate.6

There are studies that show that e ecti e patient education can mitigate the nocebo e ect in biosimilar use, where an ad erse event occurs that cannot be attributed to the therapy and may be psychosomatic.7 Instances of potential nocebo e ects ha e shown to be less pre alent when patients are con dent and informed about the safety and e cacy of biosimilars.7 A 2022 Pharmacy Market Outlook report from Vizient suggests that payers will structure formulary lists using one of three strategies when adalimumab biosimilars enter the U.S. market.8 The three strategies include: preferring the reference product, preferring at least one biosimilar, or covering the biosimilars and reference product at parity.8 While arguments have been made for di erent approaches, the two latter strategies — preferring one biosimilar or covering biosimilars and reference product at parity — would more e ecti ely increase mar et competition and generate cost savings than preferring the reference product exclusively. A 2020 survey showed that U.S. payers preferred biosimilars on formulary in 14% of coverage decisions, and speci cally, and of U. . payers preferred reference infliximab RE I DE®) over biosimilars RENFLEXIS® and INFLECTRA®, respectively.9 This may result in a loss of cost savings, according to a report from the Department of ealth uman er ices O ce of Inspector eneral, which suggests that by preferring reference products over biosimilars, Medicare Part D plans missed $84 to $143 million in savings in 2019.10 This does not account for the potential loss in savings for commercial payers. In 2019, Health New England reported saving $1.7 million by encouraging the use of biosimilar infliximab, which reached utili ing in collaboration with Magellan Rx Management.11 Payers should evaluate potential strategies to determine which is the most appropriate for their organization, re-examining formulary tiers and savings programs.12 Notably, some states may work toward legislation to override payer preferences, requiring coverage for biosimilars; state legislators in innesota ha e begun wor ing on such an e ort.12, 13 According to the Magellan Rx Management Medical Pharmacy Trend Report, an increasing number of payers have been adjusting reimbursement strategies to incentivize biosimilar prescriptions, with most payers indicating biosimilar pricing as having the biggest impact on reimbursement decisions.14 The second-biggest influence in the decision process was pro ider willingness to switch patients from reference products to biosimilars.14 Payers may want to focus on assessing reimbursement agreements to ensure they are best managing this category, ensuring patients have access to appropriate therapies and patients and payers ali e are bene ting from cost sa ings.

emophilia Innovative Therapies and Payer Management With the recent approval of etranacogene dezaparvovec for hemophilia B and more potential gene therapies in the pipeline for blood disorders, hemophilia will be a high-priority management category for payers.

Hemophilia is a bleeding disorder in which the blood does not clot properly, leading to spontaneous bleeding or bleeding following injuries or surgery.1 It is often inherited and is caused by a mutation or change in one of the genes that provides instructions for creating the clotting factor proteins needed to clot blood.1 emophilia is an -lin ed recessi e disorder, predominantly a ects males, and is ery rare in females due to the genes being located on the X chromosome. Females are typically asymptomatic carriers of hemophilia. Fewer than 200,000 individuals in the U.S. are living with hemophilia.1 The most common type of hemophilia is hemophilia A, which occurs in one in 5,000 male births and is caused by a lack of or decrease in clotting factor VIII (FVIII).1, 2 Hemophilia B occurs in one in 25,000 male births and is caused by lack of or decrease in clotting factor IX (FIX).1, 2 Gary Tereso, Pharm.D. Director of Pharmacy Health New England

Common symptoms associated with both types of hemophilia include bleeding into the joints or skin, bleeding of the mouth and gums, bleeding after surgery or after receiving shots or injections, bleeding in urine or stool, and frequent, hard-to-stop nosebleeds. Individuals with hemophilia can be at risk for more severe bleeds, like gastrointestinal bleeds or intracranial hemorrhages.

Treatment Hemophilia A is mainly treated via concentrated FVIII product; the two types of clotting factors are: plasma-derived, made from human plasma, and recombinant, lab-developed via DNA technology.3

10 | Magellan Rx Report | Spring 2023

Recombinant FVIII products are used about 75% of the time.1,3 For patients with severe hemophilia A, prophylactic FVIII treatment is typically used to prevent bleeds. The patient will receive treatment on a regular schedule, which can vary from every day to twice wee ly, depending on the product and how the speci c patient responds to treatment.3 The National Hemophilia Foundation’s edical and cienti c d isory ouncil recommends prophylaxis as optimal management for all individuals with severe hemophilia A.3 In February, the FDA approved ALTUVIIIO™ ([antihemophilic factor (recombinant) Fc-VWF-XTEN Fusion rotein-ehtl , ano , a rst-in-class VIII replacement therapy indicated for routine propylaxis and on-demand treatment to control bleeding episodes, as well as perioperative management for adults and children with hemophilia A.4 The main treatment for hemophilia B is FIX replacement therapy, using either recombinant FIX or plasma-derived FIX concentrates.5 Replacement therapy can be used as needed in patients with mild to moderate hemophilia B. However, regular infusions may be used to prevent bleeding in individuals with severe hemophilia B.5 In individuals with severe hemophilia B, prophylactic therapy has been shown to reduce complications associated with recurrent bleeding.5 FIX replacement therapy may be administered at home, which is key for individuals with severe disease as well as mild to moderate, as infusion is most e ecti e at limiting bleeding when administered within an hour of onset.5

In November 2022, the FDA approved etranacogene dezaparvovec (HEMGENIX®, CSL Behring) as the first gene therapy to treat adults with hemophilia B. Other nonfactor replacement therapies for hemophilia A help pre ent bleeding or assist in better clotting using di erent methods. Emicizumab (HEMLIBRA®) is a FVIII mimetic, which imitates the way FVIII works — bringing together IX and X and allowing the blood to clot.3 Emicizumab was approved by the U. . ood Drug dministration D in 20 for people with hemophilia A with inhibitors and in 2018 for people with hemophilia A without inhibitors.3 MASAC concluded that individuals with hemophilia A with inhibitors experiencing spontaneous or traumatic bleeding episodes would derive signi cant bene t from emici umab prophylaxis it was gi en a recommendation for rst-line therapy.6 MASAC noted that individuals on prophylactic bypassing agent with few bleeding episodes could consider switching to emicizumab based on cost-e ecti eness, reduced administration burden, and superior hemostatic e cacy.6 Desmopressin can be used for joint and muscle bleeds, nose and mouth bleeds, and before and after surgery in patients with mild hemophilia A.3 Aminocaproic acid is used to prevent the breakdown of blood clots, often before dental procedures and to treat nose and mouth bleeds in patients with hemophilia A and B.3 MASAC recommends that a dose of clotting factor should be ta en rst to form a clot, then aminocaproic acid can be used to preserve the clot and keep it from being broken down prematurely.3

Gene Therapies Etranacogene dezaparvovec (HEMGENIX®) In November 2022, the FDA approved etranacogene dezaparvovec (HEMGENIX®, ehring as the rst gene therapy to treat adults with hemophilia B.7 Etranacogene dezaparvovec is an adeno-associated virus vector-based gene therapy for adults with hemophilia B who currently use FIX prophylaxis therapy, or have current or historical

life-threatening hemorrhage, or have repeated, serious spontaneous bleeding episodes.7 The treatment is a one-time single-dose gene therapy given by IV infusion. In one study with 54 participants, adult men ages 18 to 75 with severe or moderately severe hemophilia B, the subjects had increases in FIX activity levels, a decreased need for routine FIX replacement prophylaxis, and a 54% reduction in annualized bleeding rate (ABR) compared to baseline.7-9 Adverse reactions associated with etranacogene dezaparvovec included liver enzyme elevations, headache, mild infusion-related reactions, and flu-li e symptoms.7, 9 Patients receiving the gene therapy should be monitored for adverse infusion reactions and transaminitis in their blood.7, 9 The Institute for Clinical and Economic Review (ICER) published an evidence report concluding that there is moderate certainty of a small or substantial health bene t with high certainty of at least a small net health bene t for etranacogene de apar o ec

compared with FIX prophylaxis.10 The I ER health bene t price benchmark (HBPB) for etranacogene dezaparvovec is $2.93 million to $2.96 million.10 ICER noted that the drug will become more cost-e ecti e the more durable it is.10 Etranacogene dezaparvovec will have a list price of $3.5 million.

Valoctocogene roxaparvovec (ROCTAVIAN™) In October 2022, BioMarin announced that the FDA accepted the Biologic License Application (BLA) resubmission for valoctocogene roxaparvovec gene therapy for adults with severe hemophilia A.11 Valoctocogene roxaparvovec is an adeno-associated virus-based gene therapy vector containing a coagulation FVIII complementary DNA driven by a liver-selective promoter.12 The BLA included data from the GENEr8-1 phase 3 study.

With the recent approval of etranacogene dezaparvovec for hemophilia B and more potential gene therapies in the pipeline for blood disorders, hemophilia will be a highpriority management category for payers. in the mean ABR and mean annualized FVIII infusion rate.11 The mean annualized rate of FVIII concentrate use and treated bleeding after four weeks had decreased after infusion by 98.6% and 83.8%, respectively. All participants reported at least one adverse event; the most common adverse events were headache, nausea, and elevations in aspartate aminotransferase levels.11, 12 A decision from the FDA is expected on March 31, 2023.11 ICER noted in a November 2022 evidence report that there is moderate certainty of a comparable, small, or substantial

health bene t with high certainty of at least a comparable net health bene t for aloctocogene roxapar o ec compared to FVIII prophylaxis.10 ICER’s HBPB for valoctocogene roxaparvovec ranges from $1.958 million to $1.963 million.10

Payer Impact: Gene Therapy Strategies With the recent approval of etranacogene dezaparvovec for hemophilia B and more potential gene therapies in the pipeline for blood disorders, hemophilia will be a high-priority management category for payers.13 This new gene therapy has set a new record for the most expensive single-use gene therapy in the U.S. However, current treatment costs, speci cally prophylactic treatment costs, are signi cant for patients with se ere hemophilia , the cost of regular infusions over a lifetime could cost up to $20 million per patient.13 Thus, despite the high list price of the gene therapy, the cost burden may not be as signi cant considering the o set cost of the regular prophylactic infusions.13 However, the durability of etranacogene dezaparvovec is not yet known. Payers also must consider the rate at which members switch payers, limiting the long-term cost bene t.

Value-based pricing arrangements, such as milestone-based reimbursement strategies, will likely be implemented, which have been used in the management of other high-cost gene and innovative therapies. These arrangements help mitigate the impact of the high upfront costs per dose.

Alzheimer’s Disease: New Therapies and Management Strategies ayers and manufacturers will ha e to e ecti ely collaborate to manage costs, ensure access, and improve outcomes in this patient population.

The most common cause of dementia in older adults, Alzheimer’s disease (AD), is an irreversible, progressive brain disease that deteriorates memory and cognition.1 The cause of AD is thought to be abnormal build-up of protein around brain cells. Amyloid protein deposits form plaques around brain cells and tau protein deposits form tangles within brain cells.2

Kathryn Canaday, Pharm.D. Vice President, Pharmacy and Clinical Drug Management Medical Mutual of Ohio

The initial symptoms of D may manifest di erently across the patient population, though memory problems are typically one of the rst signs.1 Other symptoms can include decline in other aspects of thinking, vision and spatial issues, and impaired reasoning or judgment.1 Mild cognitive impairment can be an early sign of AD; however, not all individuals with mild cognitive impairment will develop AD.1 s the disease progresses, indi iduals with D will ha e increasing di culty completing e eryday tas s and may become repetiti e, get lost easily, lose items, or nd simple concepts confusing. Emotion dysregulation may increase as AD progresses as well.1, 2 Diagnosis of AD is challenging because brain changes can occur long before clinical symptoms manifest or are detected.3 The progression of AD occurs in three phases: preclinical, mild cognitive impairment, and dementia dementia is further strati ed into mild, moderate, and se ere stages. The preclinical phase includes potential biological changes in the brain, but no symptoms. In the mild cognitive impairment phase, mild symptoms manifest that most likely do not interfere with daily activities and may go unnoticed and undiagnosed. Progression through the dementia phase is determined by the interference with everyday activities on a continuum from some to many to most being unable to be completed. actors including age, genetics, and sex can influence how uic ly patients progress through the phases of disease.3

ALZHEIMER’S DISEASE | Continued

Diagnosis of AD currently includes a combination of symptom reporting, cognitive testing, and a series of lab testing, such as CT scans, MRIs, or PET scans, that work to rule out other conditions that may potentially contribute to cognitive changes.1-3 PET scans pro ide analysis of proteins from cerebrospinal fluid. While no validated blood biomarkers are currently known for AD, three cerebrospinal fluid biomar ers, including β42, total tau protein, and phosphorylated tau, can be used as biomarkers for diagnosis.3 Recommended diagnosis per the International Working roup includes both the presence of biomar ers and speci c phenotypes common to D for con rmed diagnosis.3 Despite this recommendation, biomarker data is not commonly used in clinical practice. MRI is often used to show contrast between gray and white matter.1, 3 More than 6 million adults in the U.S. age 65 or older have AD. If population trends continue and the U.S. population continues to age, the number of those li ing with D will increase signi cantly over the next decade.1 The vast majority of AD cases occur in individuals 65 or older, which is described as late-onset AD. Early-onset AD occurs in individuals between ages 30 and 65 but is very rare. After initial diagnosis, the life expectancy of individuals with AD can average four to eight years; some patients with AD may live up to 20 years after diagnosis, with more than 40% of that time spent in the severe stage.1 In the late progression of AD, nonmemory symptoms such as immobility, di culty swallowing, and malnutrition become pre alent, which impact acti ities of daily li ing, correlate with signi cant morbidity, and decrease autonomy and quality of life.3 Caregiver burden in this stage is signi cant, as it is estimated that more than 11 million Americans provide unpaid care for patients with AD and associated dementias.3 AD carried a cost burden of $321 billion in 2022, in addition to an estimated $271 billion in unpaid caregiving.4

Current Treatment Landscape Treatment and management of AD is dynamic, multifactorial, and multidisciplinary. Currently, there are three FDA-approved cholinesterase inhibitors — donepezil, galantamine, and rivastigmine — and an N-methyl-D-aspartate-antagonist, memantine.3, 5 These approved treatments are all similarly associated with improvement above baseline on cognitive measures on the AD Assessment Scale cognitive subscale.3 Galantamine and oral rivastigmine are indicated for mild to moderate AD, while donepezil and transdermal rivastigmine are indicated for mild, moderate, or severe AD.3, 5 Memantine can be added to a treatment regimen if a patient progresses to severe AD while on these drugs,

16 | Magellan Rx Report | Spring 2023

This approval makes lecanemab the second of a new category of approved AD medications that target the pathophysiology. and in some cases, the combination of donepezil-memantine is used as a monotherapy. Current standard treatment for AD focuses on symptom impro ement thus, e ecti eness will decrease o er time as the disease progresses.3, 5 Currently, there is no cure for AD. Two FDA-approved medications target the fundamental pathophysiology of the disease, and others are under review.5 In June 2021, the FDA approved aducanumab (ADUHELM®, a monthly intravenous immunoglobulin gamma 1 monoclonal antibody) for the treatment of AD.6 The accelerated approval of aducanumab was based on a post-hoc analysis of the EMERGE trial, which found reduction of amyloid plaques for the primary surrogate endpoint in patients treated with high-dose aducanumab. The FDA concluded that the reduction in amyloid plaques is likely to provide clinical bene t.6, 7 In July 2021, the FDA approved a label revision clarifying the indication to include initiation in patients with mild cognitive impairment or mild dementia stage of disease, as this was the population in which aducanumab was initiated in clinical trials. Along with the accelerated approval, the FDA required an additional trial to e aluate the safety and e cacy of aducanumab, to be completed by 2030.6, 7 In 2021, the Institute for Clinical and Economic Re iew I ER concluded that the health-bene t price benchmark range for aducanumab is $3,000 to $8,400 per year, compared to the list price of $56,000.8

Lecanemab (Leqembi™) In January, the FDA approved lecanemab-irmb (Leqembi™) for the treatment of AD.9 This approval makes lecanemab the second of a new category of approved AD medications that target the pathophysiology. The FDA granted lecanemab accelerated approval based on the results of a phase 2b randomized, controlled clinical trial con rming the drug’s clinical bene t.9 In the phase 2b study of 856 patients with AD, treatment was initiated in patients with mild cognitive impairment or mild dementia disease stage and con rmed presence of amyloid beta pathology.10 The patients randomized to receive treatment with lecanemab experienced signi cant dose- and time-dependent reduction in amyloid beta plaque.10 Patients receiving 10 mg/kg of lecanemab every two

wee s had a statistically signi cant reduction in brain amyloid plaque from baseline to week 79, while those receiving placebo had no reduction of amyloid beta plaque.10 Results from a phase 3 study of 1795 patients randomized to receive lecanemab or placebo showed the mean change from baseline CDR-SB score

was less in patients receiving lecanemab than placebo (1.21 vs.

1.66, respectively).11 A further sub-study of 698 patients showed greater reductions in brain amyloid burden with lecanemab, compared to placebo.11 Treatment with lecanemab comes with a warning for amyloid-related imaging abnormalities (ARIA).9

Payer Impact

An expansive pipeline shows promising treatment opportunities for AD on the horizon. In January, the FDA declined to grant accelerated approval to donanemab, which would have been the third amyloid-targeting therapy indicated for early AD.12 The FDA noted that approval would require safety data on at least 100 patients who have taken donanemab continuously for at least a year. There is an ongoing phase 3 trial (TRAILBLAZER-ALZ 2), which may provide the required data for the traditional approval pathway.12 Previously, donanemab was investigated investigated for safety and e cacy in the TR I ER, TR I ER2, and TRAILBLAZER-ALZ 3 studies. It was assessed head-to-head with aducanumab in the TRAILBLAZER-ALZ 4 study.13 Results from TR I ERshowed signi cant reduction in the primary outcome of change in Integrated AD Rating Scale from baseline (-6.86 donanemab vs. -10.6 placebo) (32%) at 76 weeks.13 In the TRAILBLAZER-ALZ 4 trial, after six months, donanemab achieved

Strategic management and policymaking by the Centers for edicare edicaid er ices will be ey mo ing forward, as analysts suggest 96% of the market for AD treatments in the pipeline are in the Medicare population.15 ost e ecti eness of new AD treatments is an important starting point for setting value-based prices. An important negotiation point for payers and manufacturers may be performance warranties, which help to apportion risk associated with initial treatment.15 Subscription payment plans may be a useful tool to address a ordability as more no el therapies for AD become available.15 As seen in other disease states with inno ati e therapies, di erent alue-based agreements may be a solution for a variety of costly treatment options in this space.15 owe er, in order to be e ecti e, they would re uire e cient care models for screening and treatment.

PMPM Trend

Historically, the norm was a year-over-year PMPM trend ranging from 6% to 17% across all three lines of business. In 2020 to 2021, the impact of COVID and biosimilars resulted in much smaller trends of 3.2%, 2.7%, and 0% for commercial, Medicare, and Medicaid, respectively.

Top Drug Spend Trend

The top 20 medical bene t drugs had spend trends of 0 or greater, dri en by utilization increases for commercial and Medicare, and driven evenly by both cost and utilization for Medicaid.

Oncology Trend

Oncology, a top concern for all surveyed plans, continued to be the top spend category, accounting for 39%, 53%, and 27% of commercial, Medicare and Medicaid spend, respectively.

Biosimilars Trend

Since 2019, oncology biosimilars have contributed to a dramatic estimated 7% reduction in total oncology PMPM spend for commercial markets, as well as 1.6% and 0.5% reductions in Medicare and Medicaid markets, respectively.

Since the enactment of the Orphan Drug Act of 1983, more than 600 orphan drugs and biological products have been approved in the U.S.3 Exciting progress continues to be made despite challenges in researching and developing treatments for rare diseases. Challenges include the complex biology of many rare diseases, as well as variation or subtypes within a particular rare disease.3 Determining endpoints or outcome measures in trials can be di cult if nowledge of the natural history of the disease is limited.1 dditionally, populating the trials can be di cult, as rare diseases ha e small patient populations.1 Even in the face of these challenges, promising advancements continue. Some include the rst treatments directed at the underlying causes of cystic brosis, ad ances in targeted therapies for blood cancers, and therapies that prevent or slow extremely rare conditions such as pulmonary arterial hypertension, hereditary angioedema, and Gaucher disease.3 Many rare pediatric diseases, such as hypophosphatasia and neuroblastoma, now have available treatments.3 The U. . ood Drug dministration D ’s enter for Drug E aluation and Research DER is focused on facilitating the development of therapies for rare diseases.1 In 2022, more than half of CDER’s novel drug approvals were treatments for rare, or orphan, diseases.

from these therapies and ensuring them access and coverage are challenges that fall to payers.2 This includes determining whether these specialty drugs should be billed through medical or pharmacy bene t, pro iding le erage to pro iders to ensure treatment is covered based on the place of administration.2 Because of the high cost, input from medical specialists can help with understanding the value of certain therapies. Particularly in the space of rare diseases, informed decisions can be challenging to reach as sample sizes in trials are small, data is limited, and outcomes and impact of therapy are di cult to assess.2 In rare diseases where only one treatment is available, the top priority of payers will likely be to ensure patients are receiving the appropriate treatment for their diagnosis.

once a diagnosis is complete. Care coordinators or managers can be particularly helpful for patients with rare diseases, or their parents and caregivers, to understand their diagnosis and the next steps, as information may be limited.2 In a roundtable of payers focusing on rare diseases, participants noted that use of high-cost agents is easier to justify if the agent targets a speci c genetic mar er associated with the disease.2 Payers also see value in manufacturers providing education and patient support. There may be opportunity for manufacturers to assist payers and providers in identifying these rare diseases, providing support in diagnosis, and accessing care.2

CAR-T Therapy: Update and Payer Impact As currently approved CAR-T therapies expand their indications, and additional therapies move through the pipeline, this exciting opportunity and innovation will continue to create challenges and priorities for payers.

Chimeric antigen receptor T-cell (CAR-T) therapy is an innovative type of immunotherapy that uses a patient’s own immune system to help ght their cancer by collecting T-cells from the patient’s body and genetically modifying them to destroy cancer cells before infusing them back into the patient.1 CAR-T therapy has been an exciting and promising advancement in the oncology space.

Current CAR-T Landscape

Anja Shaughnessey, Pharm.D., PRS, R.Ph. Senior Pharmacy Program Manager Point32Health

There are currently six U. . ood and Drug dministration D -appro ed R-T therapies the rst one was approved in 2017. All of the currently approved CAR-T therapies are indicated for hematologic malignancies, in the second-line or later settings, but some experts anticipate a shift in place in treatment for CAR-T therapies in the near future.2 See Table 1 for a breakdown of approvals and indications.

Autologous vs. Allogeneic Currently available CAR-T therapies are autologous, meaning a patient’s own immune cells are used to produce the therapy. By 2020, there were several manufacturers focusing on the development of allogeneic o -the-shelf R-T therapies, which use T-cells from healthy donor blood or umbilical cord blood. In October 2021, the FDA placed a hold on clinical trials for AlloCAR T™ (Allogene Therapeutics), which is allogeneic, after a report of chromosomal abnormality was detected after a single dose of AlloCAR T™ administration in one patient. The hold was lifted in January 2022.3 The use of allogeneic CAR-T cells may have promising advantages over autologous therapy, including immediate access to cryopreserved product for on-demand patient treatment, potential standardi ation of R-T cell product, time for multiple cell modi cations, redosing or combination of R-T cells directed against di erent targets, and lower costs using an industriali ed process.4 However, there are several concerns and challenges associated with allogenic CAR-T therapies: understanding the risk of chromosomal abnormalities, quality control, durability, T-cell exhaustion, qualifying material, and batch-to-batch variability.5

Recent CAR-T Approvals Ciltacabtagene autoleucel (CARVYKTI™) In February 2022, the FDA approved ciltacabtagene autoleucel (cilta-cel) (CARVYKTI™; Janssen Biotech Inc.) for the treatment of adult patients with relapsed or refractory multiple myeloma after four or more prior lines of therapy, including proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody.6 Cilta-cel is a B-cell maturation antigen (BCMA)-directed, genetically modi ed autologous R-T therapy, with each dose customi ed using collected and modi ed T-cells from the patient that are then infused back into the patient.6 CARTITUDE-1 was an open-label, multicenter clinical trial evaluating the safety and e cacy of cilta-cel.7 The trial evaluated cilta-cel in 97 patients with relapsed or refractory multiple myeloma who received at least three prior lines of therapy, including a proteasome inhibitor,

an immunomodulatory agent, and an anti-CD38 monoclonal antibody and who had disease progression on or after the last chemotherapy regimen.7 Overall response rate and duration of response established e cacy, as e aluated by an Independent Review Committee (IRC) using the International Myeloma Working Group Uniform Response Criteria for Multiple Myeloma.7 Results showed the overall response rate was 97.9%, and among the 95 patients who responded, median duration of response was 21.8 months with a median duration of follow-up of 18 months.7 Cilta-cel comes with a boxed warning for cytokine release syndrome (CRS), hemophagocytic lymphohistiocytosis/macrophage activation syndrome, Immune E ector ell- ssociated Neurotoxicity Syndrome, Parkinsonism and Guillain-Barré syndrome and their associated complications, and prolonged and/or recurrent cytopenia.6 Janssen is required by the FDA to conduct a postmarketing observational study of patients treated with cilta-cel to evaluate and assess long-term safety.6

Axicabtagene ciloleucel (YESCARTA®) The FDA approved axicabtagene ciloleucel (axi-cel) (YESCARTA®, Kite Pharma Inc.) for adult patients with large B-cell lymphoma, refractory to rst-line chemoimmunotherapy or relapses within 2 months of rst-line chemoimmunotherapy in pril 2022.8 E cacy was established in the U - randomi ed, openlabel, multicenter trial of adult patients with primary refractory large B-cell lymphoma or relapse within 12 months following completion of rst-line chemoimmunotherapy.9 In the trial, 359 patients were randomized to receive a single infusion of axicel after fludarabine and cyclophosphamide lymphodepleting chemotherapy or to second-line standard therapy (two or three cycles of chemoimmunotherapy followed by high-dose therapy and autologous hematopoietic stem cell transplantation [HSCT] in patients attaining complete remission or partial remission).9 The primary e cacy measure, e ent-free sur i al, was signi cantly longer in the axi-cel arm with a hazard ratio of 0.40; estimated 18-month event-free survival was 41.5% in the axi-cel arm compared to 17% for standard therapy.8 Estimated median event-free survival was longer for patients on axi-cel compared to standard therapy (8.3 months vs. 2 months).9 The best ob ecti e response rate was statistically signi cantly higher for

patients on axi-cel compared to standard therapy (83% vs. 50%, respectively).9 About 35% of patients receiving standard therapy received on-protocol HSCT, and lack of response to chemotherapy was the most common reason for not receiving the HSCT.9 The axicel label carries a warning for CRS and neurologic toxicities.8 Previously, axi-cel was approved by the FDA in 2017 for the treatment of adult patients with certain types of large B-cell lymphoma who had not responded to or who had relapsed after at least two other kinds of systemic treatment.10 Subsequently, in 2021, the FDA granted accelerated approval to axi-cel for the treatment of adult patients with relapsed or refractory follicular lymphoma after two or more lines of systemic therapy.11

Tisagenlecleucel (KYMRIAH®) Tisagenlecleucel (tisa-cel) (KYMRIAH®, Novartis Pharmaceutical Corporation) was granted accelerated approval in May 2022 for the treatment of adult patients with relapsed or refractory follicular lymphoma after two or more lines of systemic therapy.12 In the primary e cacy analysis, the E R trial e aluated tisacel in 90 adult patients who were refractory or relapsed within

six months after completion of two or more lines of systemic therapy (including an anti-CD20 antibody and an alkylating agent) or relapsed after HSCT.13 Tisa-cel was administered after lymphodepleting chemotherapy as a single intravenous infusion with a target dose of 0.6 to 6.0 x 108 CAR-positive viable T cells.13 The main e cacy endpoints, o erall response rate and duration of response, were determined by an IRC.13 Results showed an overall response rate of 86% with a complete response rate of 68%. Median duration of response was not reached with 75% of responders still within response at nine months.13 The most common adverse reactions were CRS, infection, fatigue, musculoskeletal pain, headache, and diarrhea.12 Like axi-cel, tisacel carries a boxed warning for CRS and neurologic toxicities and is available only through a restricted program under a REMS. In 20 , tisa-cel was the rst R-T therapy the D appro ed, indicated forthe treatment of patients up to age 25 with B-cell precursor acute lymphoblastic leukemia that is refractory or in second or later relapse.14 The FDA granted tisa-cel supplemental approval in 2018 to treat adults with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, including di use large -cell lymphoma D not otherwise speci ed, high-grade -cell lymphoma, and D arising from follicular lymphoma.15

Lisocabtagene maraleucel (BREYANZI®) In June 2022, the FDA approved lisocabtagene maraleucel (lisocel) (BREYANZI®, Bristol Myers Squibb) to treat adult patients with large B-cell lymphoma who have refractory disease to rst-line chemoimmunotherapy or relapse within 2 months of rst-line immunotherapy refractory to or relapse after rstline chemoimmunotherapy and are not eligible for HSCT due to comorbidities or age.16 ppro al was based on e cacy results from two studies, TRANSFORM and PILOT. TRANSFORM was a trial for adult patients with primary refractory large B-cell lymphoma or relapse within 12 months of achieving complete response to rst-line therapy.17 In TRANSFORM, 184 patients were randomized to receive a single infusion of liso-cel following fludarabine and cyclophosphamide lymphodepleting chemotherapy or to receive second-line standard therapy (three cycles of chemoimmunotherapy followed by high-dose therapy and autologous HSCT in patients who attained complete or partial response).17 E ent-free sur i al, the primary e cacy measure was signi cantly longer in the liso-cel arm, with a ha ard ratio of 0.34.17 In the liso-cel arm, estimated one-year event-free survival was 45% compared to 24% in the standard therapy arm.17 Estimated median event-free survival was 10.1 months for lisocel, compared to 2.3 months for standard therapy.17 About 47%

of patients receiving standard therapy received HSCT as planned; lack of response to chemotherapy was the most common reason for not recei ing T. rogression-free sur i al was signi cantly longer in the liso-cell arm, with a hazard ratio of 0.41.17 The I OT study e aluated e cacy in transplant ineligible patients with relapsed or refractory large B-cell lymphoma after one line of chemoimmunotherapy.18 The study included patients who were ineligible for high-dose therapy and HSCT due to organ function or age but who had adequate organ function for CAR-T therapy.18 Complete response rate and duration of response were the primary e cacy measures. Of the patients who received liso-cel, 54% achieved complete response, and the median duration of response was not reached in patients who achieved complete response.18 Median duration of response was 2.1 months in patients with a best response of partial response.18 Liso-cel carries a boxed warning for CRS and neurologic toxicities and is available only through a REMS because of these risks.16 CRS occurred in 45% of patients in studies of liso-cel as a secondline therapy for large B-cell lymphoma and neurologic toxicities occurred in 27%.16 Previously, the FDA approved liso-cel in 2021 to treat adult patients with certain types of large B-cell lymphoma who had not responded to, or who had relapsed after, at least two other types of systemic treatment.19

ICER Reviews The Institute for Clinical and Economic Review (ICER) previously published a report on CAR-T therapies for treatment of B-cell malignancies in 2018 highlighting that although the pricing of axi-cel and tisa-cel aligned with patient bene t at the time, changes were needed in future pricing, payment, and delivery mechanisms to ensure patient access without threatening health system a ordability.20 In May 2021, ICER released its nal e idence report e aluating se eral treatments for multiple myeloma, including CAR-T therapies cilta-cel and idecabtagene vicleucel (ide-cel) (ABECMA®, Bristol Myers Squibb).21 ICER gave cilta-cel an e idence rating of , meaning there is moderate certainty of a small or substantial net health bene t, with high certainty of at least a comparable net health bene t.21 Both idecel and cilta-cel were determined to pro ide a net health bene t when compared to usual care. For ide-cel, the only CAR-T agent having gained FDA approval for multiple myeloma at the time of the report, a majority of panelists from ICER’s independent appraisal committee voted that it represents “low” long-term value for money at current pricing.21

As currently approved CAR-T therapies broaden their indications, and additional therapies move through the pipeline to expand CAR-T use into treatment of solid cancers, such as lung and breast cancer, and o -the-shelf R-T therapies become reality, this exciting opportunity and innovation will continue to create challenges and priorities for payers.22 Key to proper management in this space will be determining the appropriate patients for these therapies.22 Payers need to assess the full treatment landscape to properly identify which patients are CAR-T therapy candidates; deference to providers in these instances is important, but establishing appropriate policy will also be essential.22 Policies shifts may include medical necessity criteria in order to ensure these high cost therapies will be utilized

by the appropriate patients. Key opinion leaders may also be a useful resource in providing second opinions in patient selection.

With currently available CAR-T therapies, organizations will typically coordinate payment by using customized agreements on a perpatient basis, making the billing and reimbursements for these therapies complicated and burdensome.23 Yet, as more CAR-T options become available, payers have been approving and allowing access to these therapies more expeditiously.23 However, payers will still need to take time to negotiate and customize these per-patient agreements in order to optimize management in this space.23 Continued strategizing and management will be required moving forward. rafting policy that appropriately identi es populations and ensures access to new innovative therapies, whether on a patient-by-patient basis or through broader management, will be ey to payers’ ability to e ecti ely manage the cost burden of CAR-T therapy while ensuring access to the patients who may bene t most.

Oncology Update: Advances in Breast Cancer Management With the potential approval of a second oral SERD later in 2023, competition in this space could lead to better cost management.

New approvals and a broad pipeline promise advances in the treatment of breast cancer. The treatment landscape continues to shift with targeted therapies for breast cancers with di erent biomar ers.

Recent Approvals Olaparib (LYNPARZA®)

Fam-trastuzumab deruxtecan-nxki (ENHERTU®) In May 2022, the FDA approved fam-trastuzumab deruxtecan-nxki (ENHERTU®) for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received a prior anti-HER2-based regimen, either in the metastatic setting or in the neoadjuvant or adjuvant setting, and who have developed disease recurrence during or within six months of completing therapy.3 Famtrastuzumab deruxtecan-nxki was previously approved by the FDA under accelerated approval in December 2019 for adult patients with unresectable or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens in the metastatic setting.4 Approval was based on DESTINY-Breast03, the con rmatory trial for DE TINY-0 , a multicenter, open-label, randomized trial that enrolled 524 patients with HER2-positive, unresectable, and/or metastatic breast cancer who received prior trastuzumab and taxane therapy for metastatic disease or developed disease recurrence during or within six months of completing neoadjuvant or adjuvant therapy.4 Patients received either fam-trastuzumab deruxtecan-nxki or ado-trastuzumab emtansine by intravenous (IV) infusion every three weeks until unacceptable toxicity or disease progression.4 The primary e cacy outcome was progression-free survival (PFS), with overall survival and con rmed ob ecti e response rate as secondary outcome measures.4 While PFS was not reached in the fam-trastuzumab deruxtecan-nxki arm, it was reached 6.8 months in the adotrastuzumab emtansine arm. In the fam-trastuzumab deruxtecan-

4/6 inhibitor and may have received one line of chemotherapy in the advanced or metastatic setting.7 A total of 477 patients were enrolled, with 228 having ESR1 mutations. Patients were randomized to receive either elacestrant 345 mg orally once daily or standard of care (SOC) endocrine monotherapy.7 The ma or e cacy outcome was with o erall sur i al as an additional measure. Comparison of the PFS for the intention to treat and the E R groups showed a statistically signi cant di erence, demonstrating the magnitude of the bene t seen in the ESR1-mutated population.8 peci cally, in patients with the ESR1 mutation taking elacestrant, the median PFS was 3.8 months compared to 1.9 among SOC patients, representing a 45% risk reduction of progression.7 Overall, 22.3% of the elacestrant group achieved 12-month PFS compared to 9.5% of the SOC group.7 Common adverse events associated with elacestrant were musculoskeletal pain; increased cholesterol, AST, creatinine and triglycerides; decreased sodium, hemoglobin, and appetite; and fatigue, nausea, vomiting, diarrhea, headache, constipation, abdominal pain, hot flash, and dyspepsia.7

pipeline. Imminent approval decisions by the FDA of oral selective estrogen receptor degraders ERD o er particularly interesting opportunities for shifts in the treatment of breast cancer.

Vic-trastuzumab duocarmazine An intravenous anti-HER2 antibody-drug conjugate, victrastuzumab duocarmazine, is currently under review by the FDA with an expected approval decision in May 2023.8 A Biologics License Application (BLA) was accepted for vic-trastuzumab duocarma ine for the treatment of patients with ER2 unresectable locally advanced or MBC.8 Data from the phase 3 TULIP trial supported the BLA. TULIP was a multi-center, open-label, randomized clinical trial comparing vic-trastuzumab duocarmazine to physician’s choice treatment in patients with pre-treated ER2 unresectable locally advanced or metastatic breast cancer (MBC) with at least two previous MBC regimens or previous MBC treatment with ado-trastuzumab emtansine.9 Patients were randomized to receive either 1.2 mg/kg of vic-trastuzumab duocarmazine every three weeks or physician’s choice chemotherapy (lapatinib/ capecitabine, trastuzumab/capecitabine, trastuzumab/vinorelbine, or trastuzumab/eribulin mesylate).9 For patients in the vic-trastuzumab duocarmazine group, median PFS was seven months compared to 4.9 months in the physician’s choice group.9 Median overall survival was 20.4 months and 16.3

months for vic-trastuzumab duocarmazine and physician’s choice chemotherapy, respectively.9 This endpoint did not meet statistical signi cance. d erse e ents associated with treatment with ictrastuzumab duocarmazine were conjunctivitis, keratitis, and fatigue; interstitial lung disease, or pneumonitis, was reported for 7.5% of patients in the vic-trastuzumab duocarmazine group.9

cancer. Endocrine therapy is so crucial in the treatment for ER breast cancer ERDs remain e ecti e in treating some E Rbearing breast cancers that can be resistant to some anti-estrogen therapy.10 Increasing treatment options in this space will provide alternative opportunities for all stakeholders.

Management Impact

Elacestrant could potentially become a preferred endocrine monotherapy regimen in second- or third-line ER-positive/HER2negative advanced metastatic breast cancer. An oral alternative could shift the treatment landscape for breast cancer. Patients could avoid the administrative burden of the three initial fulvestrant injections and follow-up monthly injection doses.

Elacestrant could present a more e ecti e and con enient option to intramuscular ful estrant, speci cally in patients with E R mutation. With the potential approval of a second oral SERD later in 2023, competition in this space could lead to better cost management.

The recent approval of oral SERDs for breast cancer will cause shift in the management of breast cancer. Elacestrant is the rst oral SERD for the treatment of breast cancer. Currently, fulvestrant (Faslodex®) injection is the only available SERD to treat breast

Provider education will be crucial to help inform the process of selecting the appropriate population for treatment.11 Additionally, biomarker testing will be key to identifying the patients who will most bene t from treatment with these particular agents.11

This therapy is potentially a third-line treatment for MBC. Currently, the National omprehensi e ancer Networ lists tucatinib trastu umab capecitabine as the ategory preferred thirdline treatment for stage IV R or R- ER2 . inal o erall survival results are needed for vic-trastuzumab duocarmazine to determine whether it will provide improved outcomes over current preferred regimens.
