Sources and freshness

Registry sources, update timing, attribution and coverage limits for TrialGlobe.

Automated source in this release

ClinicalTrials.gov API v2 is the automated public feed. The snapshot was retrieved at 2026-09-08T13:21:16.012540+00:00 and contains 3,009 normalized active records.

Planned archive layers

The parent PharmaData architecture supports source-specific import and provenance layers for CTIS, WHO ICTRP, ChiCTR and NMPA/CDE exports. A source is not merged into public pages until access, attribution and permitted-use rules are recorded.

Freshness

Recruitment status is time-sensitive. This site reflects the retrieval timestamp above. An update schedule is not evidence of a successful refresh. Verify the original registry immediately before acting.

Not a completeness claim

Different registries can contain different records or update on different schedules. TrialGlobe states the source and build boundary instead of pretending one feed is the whole world.
