There isn't a cat in hell's chance that $ATRA gets away with just resubmitting the Allele data.

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.

Sunday: FDA tells cell and gene therapy developers not to worry about manufacturing. We got you, it's all good. We're here to help you. Marty Makary is walking through SFO shooting a video of himself to assure that THIS IS THE NEW FDA!!!! Monday: $ATRA cell therapy rejected. "... However, in a complete reversal of position by the FDA, the CRL claims that the single arm ALLELE trial, which was previously confirmed by the FDA as adequate to support the BLA filing, is no longer considered to be adequate to provide evidence of effectiveness for accelerated approval. Furthermore, the FDA stated that the trial’s interpretability is confounded due to trial study design, conduct, and analysis. The FDA’s new position is contrary to the FDA’s prior guidance to Atara, the FDA’s alignment with Atara on the clinical trial data set, and the acceptance of the trial design as a single arm study as relevant for this patient population at BLA submission. This prior alignment had been reached by Atara and the FDA through multiple, documented meetings held over the past five plus years." #JPM26
