🔬 ClinicalTrials.gov Scraper — Clinical Trial Data from the Official API

Scrape clinical trials straight from the official ClinicalTrials.gov API — no login, no API key, no blocking. This Apify Actor covers the full ClinicalTrials.gov database of 585,000+ studies worldwide, returning deep structured data: trial status, phase, sponsor, conditions, interventions, enrollment, eligibility, locations, and key dates. One run can return tens of thousands of trials.

If you need bulk clinical trial data for pharma intelligence, patient recruitment, or research, this Actor turns the world's largest trials registry into a clean, exportable dataset (JSON, CSV, or Excel).
