This stage also involves pharmacology studies to understand how the drug behaves in a living organism and pharmacokinetics to track how the body absorbs, distributes, metabolizes, and excretes it. Investigational New Drug Application To initiate human testing, the sponsoring company must submit an Investigational New Drug (IND) application to the fda.

Phase III: Large-Scale Validation Phase III trials are the largest and most critical studies, involving thousands of participants. These trials involve a larger group of hundreds of patients who have the specific condition the drug is intended to treat.
Researchers closely monitor participants to find the maximum tolerated dose and observe how the drug is metabolized. The data generated here is so substantial that it forms the primary evidence package submitted to the fda for approval.

These randomized, controlled trials are designed to confirm the drug's effectiveness, monitor side effects in a large population, and compare it to commonly used treatments. The goal here is to identify potential risks, such as acute toxicity or harmful side effects, that would make human testing too dangerous.
