Spotlight on Market Access

The growing use of biosimilars has reduced spending in the Medicare Part B program, but there are opportunities to further reduce costs — through greater use of more affordable biosimilars and through the implementation of different payment policies, according to a study published by the HHS Office of Inspector General (OIG).

The OIG analyzed the average sales prices, utilization and costs of 21 biosimilar drugs and their reference biologic products in the Medicare Part B program between 2015 and 2021. The agency found that overall use rate of biosimilars in Part B jumped from 18% in 2015 to 62% in 2021. While the adoption of biosimilars has lowered both the prices of biologics and biosimilars, Part B spending could have been reduced by $179 million in 2021 if the five biosimilars that cost less than their reference products — epoetin alfa, infliximab, bevacizumab, rituximab and trastuzumab — had been used at the same rate as the most widely used biosimilar, filgrastim.

The FDA recently approved a first-in-class agent to treat a particularly deadly cancer. The therapy signifies a promising new development in the treatment of solid tumors, which represent about 90% of all cancers in the U.S.

On Feb. 16, the FDA gave accelerated approval to Iovance Biotherapeutics, Inc.’s Amtagvi (lifileucel) for the treatment of adults with unresectable or metastatic melanoma previously treated with a programmed death receptor-1 (PD-1) inhibitor and, if BRAF V600 positive, a BRAF inhibitor with or without a MEK inhibitor. The agency gave the therapy orphan drug, regenerative medicine advanced therapy, fast track and priority review designations.

Among the issues facing health care payers, paying for multimillion-dollar cell and gene therapies (CGTs) is one of the most pressing, as evidenced during AHIP’s 2024 Medicare, Medicaid, Duals & Commercial Markets Forum, held March 12 through 14 in Baltimore. While they were mentioned by multiple speakers throughout the three-day conference, speakers at one session focused on the topic said that while approaches such as short-term milestone-based contracts and risk pools are being used, no perfect solution has emerged yet.

Many CGTs are in the pipeline, impacting potentially millions of patients and prompting many questions around affordability and accessibility, stated Sean Dickson, senior vice president of pharmaceutical policy at AHIP, during the March 12 session, titled “Cell and Gene Therapies: Regulatory Updates and Coverage Policies.” “Oncology is where it will get really interesting,” and these agents will have the greatest impact on Medicare payers.

As CMS engages in the initial round of Inflation Reduction Act (IRA)-mandated drug price negotiations with manufacturers, one of the agents on the list of Medicare Part D drugs to be negotiated has certain aspects that make it a not-so-straightforward candidate. Stelara (ustekinumab) from the Janssen Pharmaceutical Companies of Johnson & Johnson has particular qualities that could result in unintended consequences, asserts one industry expert.

Stelara is unique among the first drugs to be negotiated in that it is available in both subcutaneous and intravenous formulations. The human interleukin-12 and -23 antagonist is approved for subcutaneous use for the treatment of people at least 6 years old with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy and people at least 6 with active psoriatic arthritis. It also is approved for the treatment of adults with moderately to severely active Crohn’s disease and adults with moderately to severely active ulcerative colitis, for whom treatment is initiated with a single intravenous dose, followed by subcutaneous maintenance dosing.

With respective increases of 10.8% and 10.7% in 2023, health care spending on prescription drugs and home health care rose the fastest out of seven health care categories analyzed in a recent Altarum report.

Total national health care expenditures grew by 6.2% last year, while gross domestic product (GDP) increased by 6.3% year over year. In December 2023, health care spending accounted for 17.2% of GDP and has remained below 17.5% since January 2022. About 84% of health spending was attributed to personal health care, half of which was spent on hospital care and physician and clinical services.
