ClinicalTrials.gov Studies Scraper

This ClinicalTrials.gov scraper searches the registry of clinical studies by condition, drug, sponsor, phase, status or country and returns each study as one structured row. You get the design of the study, eligibility rules, primary and secondary outcomes, every recruiting site with its contacts and, for completed trials that posted results, the number of deaths, serious adverse events and other adverse events plus the most reported adverse event terms.

Pharma and biotech analysts, patient advocates, clinical operations teams and researchers use it to see what is being tested, who is running it and what actually happened in finished trials.

What can you do with this ClinicalTrials.gov scraper?

• Find recruiting clinical trials for a condition
• Search trials by drug or intervention name
• List all Phase 3 trials from a sponsor such as Pfizer or Novartis
• Find trials near a country or region
• Get the eligibility criteria, age range and sex for a trial
• See primary and secondary outcome measures
• Get the contact person and sites for a recruiting study
• Check adverse events reported in completed trials
• Track newly posted trials and status changes
• Export clinical trial data to CSV or Excel

How to scrape clinical trials

1. Enter a condition, a drug, a sponsor or any search term.
2. Optionally choose one or more statuses, phases or a country.
3. Set Max Items.
4. Click Start and export the dataset as CSV, Excel or from the Apify console.

How much does it cost to scrape ClinicalTrials.gov?

You pay per result: $25 per 1,000 studies plus a tiny start fee. The free plan returns up to 10 studies per run.

Good to know

• Adverse event fields are filled only for studies that posted results. For other studies they are empty and hasResults is false.
• Adverse event totals add up the event groups reported by the sponsor. Read them together with the study design.
• Long lists of sites are returned in full, so records for large multi-site trials can be big.

Who uses clinical trial data?

• Competitive intelligence teams map what rivals are testing.
• Patient groups find recruiting trials for a disease.
• Site and CRO teams look for studies that need sites in a country.
• Researchers collect safety outcomes across many studies.

FAQ

Do I need a ClinicalTrials.gov account? No. The Actor works without any login.

Does it include study results? Yes, for the safety side. You get adverse event counts and the most reported terms for completed studies with posted results.

Can I search by location? Yes, by country. Use the site lists in each record to narrow down further.

How do I follow new trials? Schedule the Actor with the same search and compare studyFirstPostDate and lastUpdatePostDate between runs.

Search ideas

• All recruiting Phase 2 trials for a rare disease
• Every study a competitor sponsors in oncology
• Completed trials with posted results for a drug, sorted by safety events
• Trials that need sites in a specific country

Combine a condition with a status and a phase to keep the result list focused.

Automate and connect

Schedule the Actor from the Apify console to refresh the data daily or weekly. Send finished datasets to Google Sheets, Zapier, Make or n8n, or trigger a webhook when a run ends, so your reports and alerts update without manual work.
