CMS’s Cell and Gene Therapy Access Model’s first focus will be on therapies for sickle cell disease, the agency said Jan. 30. The administration unveiled the model almost one year ago as one of three new models for testing by CMS’s Innovation Center to lower the cost of drugs and increase access to new treatments. The model will implement outcomes-based agreements (OBAs) for cell and gene therapies to treat sickle cell disease beginning in 2025 “and may be expanded to other types of CGTs in the future.” The administration estimates that about half of people with sickle cell disease are enrolled in Medicaid, with health care services costing about $3 billion annually. Through the model, CMS will negotiate OBAs, and states can decide whether to enter into the arrangements. “CMS will negotiate financial and clinical outcome measures with drug manufacturers and then reconcile data, monitor results, and evaluate outcomes. The CGT Access Model will begin in January 2025, and states may choose to begin participation at a time of their choosing between January 2025 and January 2026.”

Jan. 12: The FDA broadened the label of Merck & Co., Inc.’s Keytruda (pembrolizumab) to include, in combination with chemoradiotherapy, the treatment of people with FIGO (International Federation of Gynecology and Obstetrics) 2014 Stage III-IVA cervical cancer. The agency initially approved the programmed death receptor-1 (PD-1) inhibitor on Sept. 4, 2014. The indication is the drug’s third in cervical cancer and 39th overall. The application was granted priority review. That review was conducted under Project Orbis in collaboration with the Australian Therapeutic Goods Administration and the Brazilian Health Regulatory Agency, and it used the Assessment Aid. Dosing is 200 mg every three weeks or 400 mg every six weeks via a 30-minute intravenous infusion. The agent’s price for every-three-weeks dosing is $11,115; for every-six-weeks dosing, it’s $22,230.

In 2023, the FDA continued to rebound from a drop in approvals, marking the highest number in years. The agency’s Center for Drug Evaluation and Research (CDER) approved 55 novel drugs last year, and its Center for Biologics Evaluation and Research (CBER) approved 17 agents. That’s up from 37 CDER-approved therapies in 2022 and 51 in 2011. In 2022, CBER OK’d 13 agents, up from 10 in 2021. Specialty agents, such as cell and gene therapies, continued to make up a large portion of those new approvals, while the FDA approved several biosimilars, including a handful that were the first versions of their reference drugs. AIS Health, a division of MMIT, spoke with industry experts about what they view as the most notable FDA approvals of 2023.

Tyson Foods, Inc. dropped CVS Health Corp.’s Caremark PBM in favor of Rightway, a fee-based PBM partnered with Mark Cuban Cost Plus Drug Co. Rightway promises to save employers 15% on their pharmacy benefit costs. Tyson’s head of benefits, Renu Chhabra, told CNBC that concerning jumps in specialty drug spending were a key reason behind the move. CVS withheld data that Chhabra hoped to use to manage costs, she said. “We were going anywhere between 12% to 14% increases for pharmacy — and on a $200 million spend that’s quite a bit,” said Chhabra. “I wanted to look at Humira, and I wanted to see what the acquisition cost was…it was very difficult to get to those numbers. Part of this was to really get a partner who can help us organize the information, make sure we understand how to manage specialty, and really looking at how to get the best net cost.”

Dec. 8: The FDA expanded the patient population of ADMA Biologics, Inc.’s Bivigam (immune globulin intravenous, human) to include the treatment of people at least 2 years old with primary humoral immunodeficiency. The agency initially approved the therapy on Dec. 21, 2012. The initial intravenous infusion rate is 0.5 mg/kg/minute for the first 10 minutes for a dose of 300-800 mg/kg every three to four weeks. The maintenance infusion rate may be increased every 20 minutes by 0.8 mg/kg/minute up to 6 mg/kg/minute. Drugs.com lists the price of a 50 mL intravenous solution as more than $756.

Dec. 13: The FDA approved US WorldMeds’ Iwilfin (eflornithine) to reduce the risk of relapse in adult and pediatric patients with high-risk neuroblastoma (HRNB) who have demonstrated at least a partial response to prior multiagent, multimodality therapy, including anti-disialoganglioside (anti-GD2) immunotherapy. Between 700 and 800 cases of neuroblastoma are diagnosed annually in the U.S., with 90% of those before age 5. About half of those cases in children are HRNB. The agency used the Real-Time Oncology Review pilot program and the Assessment Aid. It also granted the application priority review and breakthrough drug and orphan drug designations. The recommended dosing of the tablet is based on body surface area.

This past year, the FDA continued to rebound from a drop in approvals, marking the highest number in years. The agency’s Center for Drug Evaluation and Research (CDER) approved 55 novel drugs last year, and its Center for Biologics Evaluation and Research (CBER) approved 17 agents.
