CVM GFI #169 Drug Substance Chemistry, Manufacturing, and Controls Information

FinalCenter for Veterinary Medicine08/06/2010

Description

Information on the chemistry, manufacturing, and controls (CMC) for the drug substance must be submitted to support the approval of original new animal drug applications (NADAs) and abbreviated new animal drug applications (ANADAs). This guidance provides recommendations on the CMC information for drug substances that should be submitted to support these applications. The guidance is structured to facilitate the preparation of applications submitted in Common Technical Document (CTD) format.
