Federal law (the FDA Amendments Act) requires sponsors of many clinical trials involving FDA-regulated products to register trials and report summary results on ClinicalTrials.gov, within specific timeframes tied to trial completion.
What's covered, and what isn't
The requirement generally applies to controlled trials of FDA-regulated drugs and devices studied in the U.S. or intended to support a U.S. marketing application; some early-phase or exploratory studies fall outside the mandatory registration requirement.
