New reporting from me on the FDA's rejection of Ebvallo, the cell therapy from $ATRA and Pierre Fabre intended for patients w/ a rare (and rapidly fatal) blood cancer. In late 2024/early 2025, FDA CBER staff examined the Ebvallo clinical data and recommended approval, pending resolution of manufacturing issues. But in January, CBER, now under Vinay Prasad, found the exact same Ebvallo clinical data deficient, and not approvable, even as the manufacturing issues were fixed. This is the inside story of a rare disease drug that was approvable, and then wasn't. It shows how the FDA's words of support for rare disease drugs are not matched by the agency's actions.
