ClinicalTrials.gov Search: Studies by Condition or NCT ID
Page updated
Price: $0.10 per 1,000 studies, flat on every Apify plan, no start fee. Free-plan cap: up to 100 studies per run on the Apify Free plan. Prices checked on 2026-10-16.
The ClinicalTrials.gov Search tool queries the official ClinicalTrials.gov API v2 by condition, intervention, sponsor, free text and status, or looks up a list of NCT IDs, and returns one structured row per study.
It stays within the API’s rate limits and backs off on errors. Listing a study does not mean the U.S. government has evaluated it.
Who it is for
Pharma and biotech analysts, CROs, market researchers, patient-recruitment teams and developers who need clinical trial data in a spreadsheet or pipeline.
- List every recruiting trial for a condition, with sponsors, phases and locations.
- Track a competitor's or sponsor's trial pipeline.
- Refresh status, enrollment and completion dates for a list of NCT IDs.
- Find which countries and sites are running studies for a drug or device.
