ClinicalTrials.gov Scraper – Clinical Trials Search, Export & Monitor

Search and export studies from ClinicalTrials.gov (500,000+ clinical trials and observational studies) by condition, drug or intervention, sponsor, location, recruitment status, phase and study type, or look up NCT IDs in bulk. Each row is one study with sponsor, phase, enrollment, key dates, conditions, interventions, primary outcomes, eligibility, central contact (name, email, phone), principal investigator and study sites with their contacts.

• Official ClinicalTrials.gov API v2 (U.S. National Library of Medicine). No browser, no login, no API key.
• Monitoring mode: schedule it and get only new or updated studies (changeType: new / updated) – a ready-made trial alert for a disease, drug or competitor.
• $1 per 1,000 studies. Not-found NCT IDs and unchanged studies are free.

What can I use it for?

• Pharma & biotech competitive intelligence: every phase 2/3 trial for a drug class, with sponsor, enrollment and completion dates.
• CRO / site business development: recruiting studies in your country or city, with sponsor and central contact emails.
• Patient recruitment and advocacy: recruiting trials for a condition near a location, with site contacts.
• Investors and analysts: pipeline tracking by sponsor; alerts when a study changes status.
• Research and AI datasets: structured study metadata for analysis or RAG.

FAQ

Is the data public? Yes. ClinicalTrials.gov is run by the U.S. National Library of Medicine and its API is free and public. Contacts are those published by sponsors on the study record.

How fresh is it? The API serves the live registry. lastUpdated is the date of the latest change to the record.

How does monitoring work? With onlyNew, the Actor stores each study's last-update date under your stateKey in the named key-value store clinical-trials-search-state. Next time, only new studies and studies with a newer update date are returned and charged.

Does it include results data? hasResults tells you whether results are posted; the full results section is not exported.
