ClinicalTrials.gov Scraper 🧪

Search and export clinical trial records from the official ClinicalTrials.gov API — by condition, drug, sponsor, phase, status and location. No API key, no login.

Pull clean, structured clinical-trial data straight from the U.S. National Library of Medicine's ClinicalTrials.gov registry (API v2). Filter by condition/disease, intervention/drug, sponsor, recruitment status, phase, study type and location — and get one tidy record per trial. Perfect for pharma/biotech competitive intelligence, drug-pipeline tracking, medical research, CRO market analysis and investor due diligence.

Uses the official ClinicalTrials.gov REST API v2 — public U.S. government registry data, no key required.
