Sources

ClinicalTrials.gov

Registered trial records and their available historical versions supply trial design, status, enrollment, endpoints and submitted completion dates. Sponsors are responsible for submitted registry information.

FDA and company disclosures

Regulatory events use FDA publications, SEC filings and company disclosures. A company-disclosed target action date is labeled as such and is distinct from an FDA decision.

Traceable observations

Trial edits and published calendar events link to supporting source records. Research archives preserve selected historical values. See the methodology page for coverage limits.
