Riepilogo

The Food and Drug Administration (FDA or Agency) is announcing the availability of a guidance for industry #234 entitled "Question- Based Review for the Chemistry, Manufacturing, and Controls Technical Section of Animal Drug Applications." To improve the process for submission and review of chemistry, manufacturing, and controls (CMC) information for animal drugs, the Center for Veterinary Medicine has developed a series of questions that focus on the critical scientific and regulatory issues and pharmaceutical attributes essential for ensuring the quality of new animal drug substances and products. Termed Question-based Review, these questions provide a general framework for original CMC submissions to investigational new animal drug files, generic investigational new animal drug files, new animal drug applications, abbreviated new animal drug applications, conditional approval of applications for conditional approval, and veterinary master files.
