2 ANDA Guidances Out
FDA has issued two draft guidances dealing with changes resulting from the GDUFA 2 reauthorization agreement. The first guidance, ANDA Submissions—Amendments to Abbreviated New Drug Applications Under GDUFA, explains to applicants how the review goals established as part of the Generic Drug User Fee Amendments reauthorization apply to amendments to either ANDAs or prior approval supplements (PASs) submitted to FDA under section 505(j) of the Federal Food, Drug, and Cosmetic Act. The document describes amendment classifications and categories and explains how amendment submissions may affect an application’s review goal dates. It also describes how FDA should review amendments submitted to ANDAs and PASs received before the 10/1 GDUFA 2 review goals effective date.
The second draft guidance, ANDA Submissions—Refuse-to-Receive Standards, is intended to assist applicants preparing to submit to FDA ANDAs and certain PASs. The document provides answers to questions the agency has received from applicants about an earlier guidance and the filing review process in general. The questions and answers are said to address general issues about the organization of an ANDA, filing decisions made by FDA, the review of and deficiencies related to drug master files, product quality, and bioequivalence, and clinical reviews. It is intended to clarify the deficiencies that may cause FDA to refuse to receive an ANDA, the agency says.
