ClinicalTrials.gov Search & Export

ClinicalTrials.gov Search & Export lets you search the official ClinicalTrials.gov registry by condition, drug, sponsor, phase, recruitment status, and country, and export every matching clinical trial to CSV, Excel, or JSON in one clean table.

What can this tool do?

• Search more than 500,000 registered clinical studies with the official ClinicalTrials.gov API.
• Filter by condition or disease, drug or intervention, sponsor, keywords, phase, recruitment status, and country.
• Export thousands of trials in seconds, with no page-by-page copying.
• Return sponsors and collaborators, enrollment, start and completion dates, study type, and whether results are posted.
• List trial sites as institution, city, and country, plus the number of sites and countries per trial.
• Sort by relevance, newest, or last updated, so you can run it on a schedule and catch new or changed trials.

Every row has the same fields, so CSV and Excel exports stay tidy.

Common uses

• Competitive intelligence: every Phase 2 and Phase 3 trial of a drug class or a competitor's pipeline.
• Site feasibility: which hospitals in a country run trials for a condition.
• Market research and investment due diligence on a therapeutic area.
• Weekly monitoring: sort by Last updated and schedule the run to catch new and changed trials.

Pricing

Is it legal?

The data comes from ClinicalTrials.gov, a public registry run by the U.S. National Library of Medicine, through its official API. This tool returns study and organisation information only. Names, emails, and phone numbers of investigators and study contacts are never collected, and sponsors or sites that are individual people are hidden. You are responsible for how you use the data.

FAQ

Why do I get fewer results than on the website? Check the filters: the country filter keeps studies with at least one site in that country, and phases and statuses combine with AND. totalMatching in the run's OUTPUT shows how many studies matched in total.

How do I write the country? Use the English country name, for example United States, United Kingdom, Germany. Common short forms like USA and UK also work.

Can I get the principal investigator or contact email? No. Those are personal details, so this tool leaves them out. Use the url to open the official study page.

Some trials list hundreds of sites. Are they all included? locationsCount and countries cover every site; facilities lists up to 300 sites per study to keep rows manageable.
