Phase I is the first test of a drug in humans, generally in healthy volunteers (no less then 10 subjects). Profil focuses on Phase I+II clinical trials as we are a full-service CRO for early clinical development. If, after the first three phases, researchers find a drug or other intervention to be safe and effective, the FDA approves it for clinical use and continues to monitor its effects. Phase IV trials usually are done after a treatment has been approved for use by the U.S. Food and Drug Administration.

Phase 2 studies examine whether the drug works. Doctors use phase III to compare the new treatment with the standard treatment. Phase 4 trials look at long-term safety and effectiveness. A clinical trial is only done when there is good reason to believe that a new test or treatment may improve the care of patients.
