ClinicalTrials.gov Scraper

Extract clinical trial data from ClinicalTrials.gov — the world's largest registry of clinical studies, maintained by the U.S. National Library of Medicine (NLM). This Actor wraps the official ClinicalTrials.gov v2 API to deliver structured data on over 575,000 clinical studies including drug trials, device studies, and behavioral research.

ClinicalTrials.gov data is essential for pharmaceutical competitive intelligence, biotech investment research, medical device market analysis, academic research, and patient advocacy. Every interventional study conducted in the US — and many international studies — must be registered here. This Actor makes that data instantly accessible in JSON, CSV, or Excel format.
