The fda reviews this submission, not to approve the drug, but to ensure the studies pose minimal risk to participants. Phase III: Large-Scale Validation Phase III trials are the largest and most critical studies, involving thousands of participants.
Researchers closely monitor participants to find the maximum tolerated dose and observe how the drug is metabolized. This phase answers the critical question: Is this substance tolerable in humans? Phase II: Efficacy and Side Effects If a drug proves safe in Phase I, it advances to Phase II, where the focus shifts to efficacy.
