Final answer:
The Center for Veterinary Medicine (CVM) of the FDA regulates the development and approval of animal drugs, ensuring their safety and efficacy for both food animals and pets.
Step-by-step explanation:
The Center for Veterinary Medicine (CVM), a branch of the Food and Drug Administration (FDA), regulates the development and approval of animal drugs. CVM focuses on ensuring that drugs for both food animals and pets are safe and effective, and it also oversees food additives. However, the CVM does not regulate vaccines for animals; this is the responsibility of the United States Department of Agriculture. When it comes to the development and approval of new therapies, after preclinical data from animal trials, an Investigational New Drug (IND) application must be submitted and approved by the FDA before clinical trials with human subjects can begin. The rigorous approval process, managed by the FDA, is designed to establish the safety and efficacy of treatments before they reach the market.
