Approvable letters, and the related non-approvable letters (alternately not-approvable letters), are notifications sent out by the Food and Drug Administration (FDA) to drug manufacturers alerting them to the approval prospects of their drugs under development. The letters are intended to let manufacturers know how much work is needed on their applications. Non-approval letters are rejections of a drug’s application.
Approvable letters are issued to applicants at the end of the FDA’s review period to indicate that the application or abbreviated application is basically approvable providing certain issues are resolved. It’s an indication that the application substantially meets FDA requirements if specific conditions, such as labeling changes, are agreed to. The letter describes what is required by the FDA.
Applicants have 10 days after the date of the approvable letter to amend the application, notify of intent to file for an extension, withdraw the application, request a hearing or notify that they agree to an extension.
