Clinical trial phases and registrations

What phase 1, 2 and 3 mean, and why a registered trial isn't a result.

Phase 1: usually 20 to 80 people; is it safe, and how does the body handle it?
Phase 2: up to a few hundred people with the condition; does it seem to work, at what amounts, with what side effects?
Phase 3: hundreds to thousands of people, usually randomized against placebo or standard treatment; the evidence regulators approve drugs on.

Trials are registered on ClinicalTrials.gov before they start. A registration tells you a study exists, its design and status. It isn't a result: many trials finish without publishing, and "recruiting" means it hasn't produced evidence yet. Look for posted results or a published paper.

Key points

Phase 3 trials are the basis for approval.
Registered ≠ results.
Check whether results were posted or published.
