How to Scrape ClinicalTrials.gov Studies

ClinicalTrials.gov records are deeply structured. Copying search pages discards eligibility, outcomes, sponsor classes, interventions, and site details that are already available through the official interface.

The ClinicalTrials.gov Scraper accepts condition, intervention, sponsor, location, or all-field searches. It returns normalized rows containing NCT ID, titles, status, phases, enrollment, conditions, interventions, sponsors, summaries, eligibility, outcomes, dates, contacts, locations, and results availability.

Keep NCT ID as the primary key and preserve null fields. A registered study can be incomplete, updated, terminated, or missing results; the export should reflect those distinctions. For recurring work, save the exact query and sort expression with each snapshot so changes can be audited rather than inferred from the current record alone.
