FDA

Oct. 30: The FDA gave an additional approval to Bristol Myers Squibb’s Orencia (abatacept) for the subcutaneous treatment of people at least 2 years old with active psoriatic arthritis. The agency first approved the selective T cell costimulation modulator on Dec. 23, 2005. Dosing for the newest use is 50 mg once weekly for people with a body weight of 10 kg to less than 25 kg, 87.5 mg for those with a body weight of 25 kg to less than 50 kg and 125 mg for those with a body weight of at least 50 kg. The agent also is approved for intravenous dosing of certain indications. GoodRx lists one carton of four 125 mg/mL single-dose syringes as more than $5,520.

Oct. 31: The FDA expanded the approval of Fresenius Kabi’s Idacio (adalimumab-aacf) for the treatment of adults with non-infectious intermediate and posterior uveitis and panuveitis. The agency first approved the biosimilar of AbbVie Inc.’s tumor necrosis factor (TNF) blocker Humira (adalimumab) on Dec. 13, 2022. Dosing starts with 80 mg via subcutaneous injection, followed by 40 mg every other week starting one week after the initial dose. The price of two single-dose prefilled pens or two single-dose prefilled glass syringes is $6,576.

The US Food and Drug Administration’s simultaneous approval of two gene therapies for sickle cell disease from Vertex Pharmaceuticals Incorporated/CRISPR Therapeutics AG and bluebird bio on 8 December provides the competitors an equal start out of the gate, and offers another test for the Rx policy concept that intra-class competition can drive down prices.

Based on the initial list prices, though, it seems like perhaps competition cannot do that, at least not in this case, or at least not yet. Bluebird bio’s Lyfgenia has a wholesale acquisition cost of $3.1m, while the WAC for Vertex and CRISPR’s Casgevy is $2.2m, which might be a significant handicap for bluebird in securing reimbursement.

Bayer recently revealed that it will work with the FDA to voluntarily withdraw the New Drug Application (NDA) for its cancer drug Aliqopa (copanlisib). The therapy is the latest phosphoinositide 3-kinase — also called phosphatidylinositol 3-kinase — (PI3K) inhibitor/indication with accelerated approval to treat a hematologic malignancy to be pulled from the U.S. market, potentially spurring payers to take a closer look at these agents.

The agency gave Aliqopa accelerated approval on Sept. 14, 2017, for the treatment of adults with relapsed follicular lymphoma (FL) who have received at least two systemic therapies. Approval was based on the CHRONOS-1 Phase II clinical trial. In the confirmatory study, CHRONOS-4, adding Aliqopa to standard immunochemotherapy regimens did not meet the primary endpoint of progression-free survival (PFS) vs. the standard immunochemotherapy control arm. Bayer says it will publish the trial results “in a timely manner.”

The recent approvals of the first two gene therapies for sickle cell disease represent potential major breakthroughs for patients who have faced significant burdens associated with the condition. However, there are still questions about how and whether payers will cover the high-cost treatments and how many patients will be open to taking the new treatments.

The FDA on Dec. 8 approved Casgevy (exagamglogene autotemcel) from CRISPR Therapeutics and Vertex Pharmaceuticals Inc. and Lyfgenia (lovotibeglogene autotemcel) from bluebird, Inc. for patients who are 12 or older and have recurrent vaso-occlusive events (VOEs), the term for severe pain and organ damage. The agency noted about 100,000 people in the U.S. have sickle cell disease and that VOEs “can lead to life-threatening disabilities and/or early death.”

Scrutiny of the FDA’s accelerated approval process has shown no signs of slowing, with an FDA committee holding a recent meeting on the program’s use for oncology indications, as well as on two cancer drugs lacking confirmatory trial data long after their accelerated approvals. And an FDA leader recently asserted his stance on granting the designation only when companies already have started postmarketing trials. Still, these developments should not dampen interest by either manufacturers or payers in drugs hitting the market via the accelerated pathway, says one industry expert.

The FDA established the accelerated approval pathway in 1992 to bring HIV/AIDS medicines onto the market sooner during the ongoing epidemic. Between that time and Dec. 31, 2020, the agency has granted more than 253 accelerated approvals, according to a 2021 report from the Institute for Clinical and Economic Review (ICER) examining the designation. Of those, 125 — 49.4% — later received full approval, with a median time of 3.2 years from accelerated approval to full. Sixteen — 6.3% — of the indications have been withdrawn, and the remaining 112 drugs have been on the market for a median of 1.9 years.

Zepbound (tirzepatide), Eli Lilly and Co.’s latest glucagon-like peptide 1 (GLP-1) agonist product and Lilly's first entrant in that category to be marketed only as a weight loss drug, garnered FDA approval on Nov. 8. The approval intensified already fierce public interest in using GLP-1s for weight loss — which could be bad news for payers, especially commercial plan sponsors, who were already concerned before Zepbound’s approval that the high cost and broad appeal of the drugs will cause premiums to spike.

A recent WTW survey found that 38% of employer-backed health plans cover weight loss drugs, while 22% are considering adding coverage. Mercer found that 42% of large employers cover GLP-1 drugs for weight loss. Brokers and employer plan sponsor trade groups have identified burgeoning GLP-1 utilization as a possible reason for future premium hikes.

The ulcerative colitis (UC) space has seen multiple new approvals recently that could focus payer management even more on the condition. Payers already take an aggressive approach toward managing branded agents within the class, according to a Zitter Insights survey.

While no cure exists for the inflammatory bowel disease, the FDA has approved numerous agents to treat signs and symptoms of the condition. In addition to the nine biosimilars of AbbVie Inc.’s Humira (adalimumab) that have launched in the U.S. in 2023, a handful of other therapies have been approved by the agency since late September. All of the agents offer maintenance dosing either through an oral or subcutaneous route of administration.

On March 23, 2010, then-President Barack Obama signed the Affordable Care Act (ACA) into law, establishing the 351(k) biosimilar pathway via the Biologics Price Competition and Innovation Act (BPCIA), which amended the Public Health Service (PHS) Act. Since then, the FDA has approved more than 40 biosimilars, with only a handful of those gaining interchangeable status. That designation, however, may not carry quite the distinction it historically has had if proposed guidance from the agency — which would replace previous guidance — on labeling for interchangeable biosimilars is finalized. At the same time, the change may help promote uptake of biosimilars, bringing cost savings to the U.S. health care system, say industry sources.

In contrast to the EU, whose European Medicines Agency (EMA) and the Heads of Medicines Agencies (HMA) clarified in September 2022 that all biosimilars approved in the EU are interchangeable, the FDA has created two levels of biosimilars: biosimilars and interchangeable biosimilars.

Celltrion USA, Inc. signed a contract with Ventegra to include its Yuflyma (adalimumab-aaty) as a preferred drug on its formulary in both public and private insurance markets, the manufacturer said Oct. 5. Ventegra is a “major U.S. Medical Benefits Manager (MBM) who administers pharmacy benefits through its Pharmacy Services Administration (PSA) model that has been effectively displacing traditional” PBMs. The move gives Celltrion access to approximately 3.6% of the U.S. The company says it will increase its marketing so that the drug has “coverage and/or access for 40% of the U.S. population by the end of the year.” Yuflyma, a high-concentration biosimilar of AbbVie Inc.’s Humira (adalimumab), launched in July with a wholesale acquisition cost of $6,576. Celltrion also said that Yuflyma has been added to CarePartners Pharmacy’s cost savings programs. With its partners, the specialty pharmacy has access to more than 10 million plan members. It is fully accredited and licensed to service patients in all 50 states and Washington, D.C. According to The Korea Economic Daily, “CarePartners will sidestep the original Humira from its roster and refrain from enlisting other competing adalimumab biosimilars, effectively making Yuflyma the sole adalimumab product in its offerings.”

The FDA recently approved the first biosimilar of Actemra (tocilizumab) from Genentech USA, Inc., a member of the Roche Group, for multiple indications. Both payers and rheumatologists responding to a Zitter Insights survey said they expected the new drug to have some impact on their management of and prescribing for rheumatoid arthritis (RA). However, the drug’s lack of an additional formulation may hurt its uptake, say industry sources.

On Sept. 29, the FDA approved Bio-Thera and Biogen Inc.’s Tofidence (tocilizumab-bavi) intravenous formulation for the treatment of adults with moderately to severely active rheumatoid arthritis who have had an inadequate response to at least one disease-modifying antirheumatic drug (DMARD), people at least 2 years old with active polyarticular juvenile idiopathic arthritis and people at least 2 years old with active systemic juvenile idiopathic arthritis. Dosing of the intravenous infusion is based on the indication.
