After July’s first-ever release of more than 200 complete response letters (CRLs) by the U.S. FDA, the agency now says it will release letters shortly after sponsors receive them. In addition, the FDA released a new batch of 89 CRLs from 2024 to now that are tied to pending or withdrawn applications.
It’s been more than seven years in coming, but the U.S. FDA is at last making public at least some of the complete response letters (CRLs) it’s sent to drug and biologic sponsors to notify them of deficiencies in their approval applications.
A U.S. FDA CDER official is among the first to say the quiet part out loud in proposing a Sept. 12 deadline for the agency to respond to Vanda Pharmaceuticals Inc.’s request for summary judgment or a hearing on CDER’s refusal to approve tradipitant to treat gastroparesis.

Clearly frustrated by the U.S. FDA’s rejection of tradipitant to treat gastroparesis, Vanda Pharmaceuticals Inc.
