Regulators overseeing rare disease treatments need better tools to weigh competing risks in real time. Sarepta Therapeutics’ Elevidys is a prime example of why.
Rare disease drug developers struggle to survive in a biopharma investment market that prioritizes large patient populations. Initiatives like the Orphan Therapeutics Accelerator are attempting to solve what CEO Craig Martin says is not a science problem, but a math problem.
The framework, first introduced by FDA Commissioner Marty Makary and Center for Biologics Evaluation and Research head Vinay Prasad in November, was criticized for lacking detailed guidance. Agency leaders elucidated on the pathway for personalized medicines on Monday.
The U.S. Congress greenlit a historic $315 million in federal ALS research funding for 2026 amid Rare Disease Month, spotlighting biotech progress like VectorY Therapeutics’ first patient dosing in its TDP-43-targeting PIONEER-ALS trial and EverythingALS’ pharma consortia driving biomarker innovations and trial alignment.
The first gene therapies approved to treat sickle cell disease in December 2023 are struggling on the market. But there are glimpses of forward momentum as Vertex and Genetix Bio provide updates.
FDA vouchers are normally a coveted prize for biopharma companies, but a surprise rejection for Disc Medicine’s rare disease drug has biopharma reconsidering.
The FDA outright refuses to review Moderna’s mRNA-based flu vaccine as CBER director Vinay Prasad’s conduct is scrutinized; Disc Medicine receives an unexpected rejection, which Prasad may also have had a hand in; Compass Pathways posts new late-stage data on its psilocybin-based depression drug; CDC is once again leaderless.
