What is the purpose of an Investigational New Drug (IND) application?

The primary purpose of an Investigational New Drug (IND) application is to obtain authorization from the FDA to begin clinical trials. This is a crucial step in the drug development process, as it ensures that the proposed studies are ethical and that the potential benefits of the drug outweigh any risks involved.

When a pharmaceutical company or research institution submits an IND application, it must provide comprehensive information about the drug, including the results of preclinical studies, the proposed clinical trial protocol, and plans for monitoring patient safety. The FDA reviews this application to determine whether the trials can proceed, focusing on factors such as the drug's safety profile, potential effectiveness, and the soundness of the proposed clinical methodology.

Other choices relate to different aspects of drug development and marketing but do not pertain directly to the purpose of an IND application. For instance, securing patents is related to intellectual property protection, while establishing marketing claims comes after clinical trials during the drug approval process. Registering drugs in foreign markets involves different regulatory steps that occur once the drug has been approved for use in the U.S.
