Cell and Gene Therapy
THE LATEST
On the FDA’s docket this month are two decisions pushed back from 2025, including one for a rare form of obesity and another for dry eye disease.
After a rocky 2025, Sarepta Therapeutics’ executives admit they have work to do to bring patients back into the fold as sales of Duchenne muscular dystrophy gene therapy Elevidys continue to decline.
The rejection of Atara Biotherapeutics’ Ebvallo in January was a “complete reversal” of the conesensus FDA reviewers had come to, according to a former agency employee, who said manufacturing problems were the only approvability barrier for the drug.
Regulators overseeing rare disease treatments need better tools to weigh competing risks in real time. Sarepta Therapeutics’ Elevidys is a prime example of why.
A lower court had previously ruled for Sarepta in the companies’ long-running dispute, finding that REGENXBIO’s AAV patent was invalid because its elements were naturally occurring. The appeals court on Friday said that this original decision adopts a “narrow” view of the invention.
The centerpiece of the takeover is anito-cel, a CAR T therapy under development for relapsed or refractory multiple myeloma. An FDA decision on the therapy is expected by December 2026.
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.
The FDA’s refusal to review Moderna’s mRNA-based flu vaccine is “part of a disturbing pattern” of moving regulatory goalposts, according to Clay Alspach, executive director of the Alliance for mRNA Medicines. Meanwhile, streamlined communications with regulators in other countries pave the way for rapid uptake of novel modalities.
Following over a year of slow uptake, Vertex Pharmaceuticals and CRISPR Therapeutics expect Casgevy revenues to nearly triple in 2026, as patient access to the sickle cell disease and beta thalassemia gene therapy grows.
The FDA’s refusal to review Moderna’s mRNA-based flu vaccine is part of a larger communications crisis unfolding at the agency over the past nine months that has also ensnarled Sarepta, Capricor, uniQure and many more.
