Commercial Insurance Restrictions Complicate Biosimilar Adoption

Since the FDA’s approval of the first biosimilar in 2015, the agency has approved almost 40 more agents. However, their adoption in the U.S. market has been slow. A recent study, published in the journal BioDrugs, found that biosimilars were covered more restrictively than their reference biologics in 19.4% of coverage decisions made by select commercial health plans.

The study examined 1,181 coverage decisions made by 17 commercial health plans as of August 2021 from the Tufts Medical Center Specialty Drug Evidence and Coverage database, which included 19 commercially available biosimilars for seven biologic reference products used in treating 28 conditions.

News Briefs: Drugmakers Prep Legal Challenges to Medicare Price Negotiation

Major pharmaceutical companies are gearing up to file legal challenges to the Medicare price negotiation provisions in the Inflation Reduction Act, Reuters reported. Industry sources who spoke with the news outlet said drugmakers plan to argue that a ban against discussing the price negotiation process violates their First Amendment rights, and that the $1 million per day fine for violations runs afoul of the Eighth Amendment’s protections from excessive fines. Sources also indicated that lawsuits could challenge the legality of initial guidance CMS issued in March regarding the Medicare price negotiation program, as it did not go through a formal process with proposed and final rules. Five of the world’s top drugmakers sent CMS letters raising legal concerns about the Medicare price negotiation program, but they have not yet been made public; CMS said it plans to publish the letters in July when it finalizes its guidance and regulations implementing the program.

Report: Specialty Drug Management Grows More Complex, as Plans Have Array of Strategies

Specialty drug management continues to be of utmost importance to plan sponsors, which are implementing a variety of levers to try to keep spending in check while making sure their beneficiaries are receiving appropriate care. Pharmaceutical Strategies Group (PSG), an EPIC company, recently released its 2023 Trends in Specialty Drug Benefits Report, which examines the use of these strategies and overall trends in managing these costly medications.

The report, released May 3, is the 10th annual report; it previously was published under the Pharmacy Benefit Management Institute (PBMI) brand. Conducted from Sept. 20, 2022, through Oct. 21, 2022, the survey included 182 benefits leaders from employers, unions/Taft-Hartley plans and health plans representing plan sponsors of approximately 86.7 million covered lives.

News Briefs: Celltrion Launches Vegzelma, Fourth Avastin Biosimilar in U.S.

Celltrion Healthcare Co. launched Vegzelma (bevacizumab-adcd), the company said on April 17. The FDA approved the injectable last September for multiple types of cancer, including colorectal and non-small cell lung cancer. It is the fourth FDA-approved biosimilar of Avastin (bevacizumab) from Genentech USA, Inc., a member of the Roche Group, to launch in the U.S. While the company has partnered with other companies in marketing biosimilars in the U.S., its Celltrion USA unit is taking full responsibility for this launch.

The FDA’s Oncologic Drugs Advisory Committee (ODAC) voted 11-1 that AstraZeneca and Merck & Co., Inc.’s Lynparza (olaparib) in combination with abiraterone and prednisone or prednisolone for the treatment of metastatic castration-resistant prostate cancer (mCRPC) should be limited to people whose tumors have a BRCA mutation. The FDA accepted a supplemental New Drug Application for a broader approval in mCRPC for the poly (ADP-ribose) polymerase (PARP) inhibitor last August. The class of drugs — which also includes GDK’s Zejula (niraparib) and Rubraca (rucaparib), whose rights Clovis Oncology, Inc. recently sold to pharma& Schweiz GmbH a few months after it filed for Chapter 11 bankruptcy — have been under some scrutiny after they withdrew some of their indications.

Biosimilars Market Is Expected to Grow, But Impact on Payers, Costs Remains Uncertain

The FDA is expected to approve several biosimilar medications in the next few years, potentially leading to billions of dollars in savings for payers and patients, according to a recent report from Cardinal Health. However, Bruce Feinberg, D.O., Cardinal Health’s chief medical officer, tells AIS Health that the promise of biosimilars to decrease medication and overall health care costs remains uncertain. He adds that the price differential between biologic drugs and their biosimilars has not reached anywhere near the levels seen between small-molecule medications and their generics.

Feinberg says that “in most of the biosimilars to date, none of the manufacturers have been quite willing to initiate that race to the bottom on price,” in large part due the high costs of producing biosimilars and funding research and development of them. Whereas the introduction of a generic can reduce prices by 90%, Feinberg says “we’re not seeing those kinds of changes [with biosimilars],” claiming the range is usually from 10% to 30% with an average of 15%.

California Will Join Insulin Fray With CivicaRx White Label Partnership

Amid a trend of steep insulin price cuts by Eli Lilly & Co., Novo Nordisk A/S and Sanofi S.A., the state of California said it would develop its own line of affordable insulins with Civica Rx, the nonprofit drug manufacturer that launched in 2020. Experts say that patients will finally see relief from sky-high insulin prices and drug manufacturers will maintain a healthy margin — but they add that PBMs and some payers may actually see the costs of their insulin purchasing increase as rebate revenue decreases.

California and Civica's new insulin line will, according to a Civica press release, be called CalRx and will be sold at "no more than $30 per 10 mL vial and no more than $55 for a box of five 3 mL pre-filled pens." Allan Coukell, Civica's senior vice president of public policy, tells AIS Health, a division of MMIT, that the company expects to start selling the insulin after submitting biosimilars for FDA approval starting in 2024. According to the press release, the Civica insulin line will include biosimilars glargine (which references Sanofi's Lantus), lispro (Lilly's Humalog) and aspart (Novo's Novolog).
