ClinicalTrials.gov Scraper

ClinicalTrials.gov Scraper

Scrape clinical trials from ClinicalTrials.gov by condition, intervention, location, phase, sponsor, or date, up to a million per run. Every trial comes with its status, eligibility, contacts, locations, and posted results. No API key or registration. Export to CSV, JSON, Excel, or XML.

ClinicalTrials.gov's official API needs a registered account, a token, and rate limits that throttle large exports. This reads the public study registry directly, filtered by condition, drug, phase, sponsor, location, or date, and returns each match in one fixed schema.

Who uses it	What they scrape ClinicalTrials.gov for
Market researchers	Which trials are recruiting for a given condition this quarter
Pharma competitive intelligence teams	What sponsors are running Phase 3 trials in a therapeutic area
Clinical operations teams	Which sites are active for a protocol and their contact details
Patient advocacy groups	Which recruiting trials match a disease and location for their community
Data journalists	How many trials were posted or updated in a date range for a story

What it does

This Actor collects clinical trial records from ClinicalTrials.gov by search query or direct URL, and returns each trial as a flat row.

• 🔍 Search or URL: start from a ClinicalTrials.gov search URL, an API endpoint, or build a query from condition, intervention, location, and other filters.
• 📊 Structured rows: each trial returns as one flat record with status, phase, enrollment, eligibility, contacts, locations, and posted dates.
• 🗓️ Date filters: restrict by study start, primary completion, study completion, first posted, results first posted, or last update posted.
• 🏥 Eligibility filters: filter by sex, age groups, age range, and whether healthy volunteers are accepted.
• 💊 Study filters: filter by phase, study type, results availability, document types, funder type, and FDAAA violation flag.
• 📄 Export ready: download as CSV, JSON, Excel, or XML for analysis or upload to your own database.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

What you can do with ClinicalTrials.gov data

A pharma analyst filters by lead sponsor and phase to see every Phase 3 trial a competitor has posted or updated in the last month.

🏥 Find trial sites and contacts.

A clinical operations team searches by facility name or location to get site addresses and contact emails for a specific protocol.

📊 Audit FDAAA compliance.

A compliance officer sets the FDAAA violation flag to true to list all studies flagged for results submission violations.

Configure the run

Drive the Actor from a ClinicalTrials.gov search URL or build a query from condition, intervention, location, sponsor, and other filters. Filters run as each trial is read so only matches reach your dataset. The Input tab lists every parameter.

A first run with the defaults:

{
 "startUrl": "https://clinicaltrials.gov/search",
 "maxItems": 10
}

A larger pull:

{
 "startUrl": "https://clinicaltrials.gov/search",
 "maxItems": 200
}

Pricing

Pay-per-result: $0.16 per result collected. You pay only for the results written to your dataset.

Then prompt it in plain language to run the scraper and read back the results.

Troubleshooting

Why am I getting no results?

Check that your filters are not too restrictive. Try removing some filters or broadening the condition or intervention terms. Also verify that the startUrl, if used, is a valid ClinicalTrials.gov search URL.

Why did the run stop at 100 items?

Free users are limited to 100 items per run. Upgrade to a paid plan to increase maxItems up to 1,000,000.

Why are my date filters not working?

Date fields expect YYYY-MM-DD format. Make sure you entered both From and To dates correctly and that the From date is before the To date.

Why are some fields empty in the output?

Not all trials have every field populated. For example, results first posted date is only present for trials with posted results. Empty fields are normal.

Can I use a URL from the ClinicalTrials.gov website?

Yes, paste any search URL from clinicaltrials.gov/search into startUrl. The Actor will parse the query parameters and ignore other filters.
