✨ What this Actor does / Key features

• 🔬 Extracts full trial records — 28+ structured fields per study: NCT ID, titles, status, phase, sponsor, conditions, interventions, enrollment, eligibility and locations.
• 🏥 Filter the whole registry — search by condition/disease, free-text term, lead sponsor and one or more trial statuses.
• 🌍 Global coverage — 585,000+ studies from sponsors, hospitals and research centers worldwide.
• 📍 Site-level detail — every trial site (facility, city, state, country) so you can map recruiting locations.
• 🧬 Eligibility built in — sex, age range and healthy-volunteer flags for patient-matching and recruitment.
• 🔑 No API key, no login — just set filters and run; nothing to register with ClinicalTrials.gov.
• 📤 Export anywhere — download as JSON, CSV, Excel (XLSX), XML or JSONLines, or pipe to Google Sheets, a database or a webhook.
• ⚡ Bulk-ready — one run can return tens of thousands of trials; set a cap or capture everything that matches.

🚀 Quick start (3 steps)

1. Click Try for free / Start on the Actor page (or call it via the Apify API).
2. Set your filters — condition (disease), searchTerm (free text), sponsor, and overallStatus. Set maxStudies to cap the run, or 0 for everything that matches.
3. Run the Actor and download the results as CSV, JSON or Excel — or connect Google Sheets, a database or a webhook.

📥 Input

No input is required — run with the defaults to sample the registry, or set filters to target exactly the trials you need.

Example — Recruiting breast-cancer trials

{
  "condition": "breast cancer",
  "searchTerm": "",
  "sponsor": "",
  "overallStatus": ["RECRUITING"],
  "maxStudies": 10000
}

Example — A pharma sponsor's full pipeline

{
  "condition": "",
  "searchTerm": "",
  "sponsor": "pfizer",
  "overallStatus": [],
  "maxStudies": 5000
}

Example — Completed Phase 3 immunotherapy studies

{
  "condition": "",
  "searchTerm": "immunotherapy",
  "sponsor": "",
  "overallStatus": ["COMPLETED"],
  "maxStudies": 2000
}

Field	Type	Description
condition	string	Filter by condition or disease, e.g. diabetes, breast cancer, alzheimer. Leave empty for all.
searchTerm	string	Free-text search across the whole study record (intervention, sponsor, keyword). Leave empty for all.
sponsor	string	Filter by lead sponsor, e.g. pfizer, moderna, national cancer institute. Leave empty for all.
overallStatus	array	Filter by trial status, e.g. RECRUITING, COMPLETED, ACTIVE_NOT_RECRUITING. Leave empty for all.
maxStudies	integer	Maximum studies to save. 0 = all matching (up to ~585,000 across the whole database).

💡 Tip: Combine condition + overallStatus: ["RECRUITING"] to build a live patient-recruitment list, or set only sponsor to pull a competitor's entire trial portfolio across every phase and status.

📤 Output

Each dataset item is one clinical trial study. Here is a realistic (trimmed) sample:

❓ Frequently Asked Questions

Is this an official ClinicalTrials.gov API or a scraper? It reads data from the official ClinicalTrials.gov data registry, so the data is authoritative and stable. This Actor turns that registry into filtered, structured, ready-to-export datasets. It is not affiliated with ClinicalTrials.gov, the NIH or the US National Library of Medicine.

Does ClinicalTrials.gov have an API? Yes — ClinicalTrials.gov publishes an official public data API. It's powerful but returns deeply nested, paginated JSON that most people still have to parse, flatten and stitch together themselves. This Actor does that work for you: it queries the source, flattens every study into 28+ clean columns, handles pagination automatically, and hands you a tidy CSV/JSON/Excel dataset — no code, no rate-limit management.

Do I need an API key or login? No. There is no ClinicalTrials.gov API key to register and no login — you only need an Apify account. Just set your filters and run.

Can I use this without writing code or building an API integration? Absolutely. It's fully no-code: set your filters in the form, click Start, and download the results. Developers can also run it via the Apify API or schedule it, but no integration work is required.

How do I export ClinicalTrials.gov data to CSV or JSON? Run the Actor with your filters, then download the dataset as CSV, JSON, Excel (XLSX), XML or JSONLines from the run page — or fetch it through the Apify API. It turns the trial registry into a clean clinical trials dataset ready for analysis.

How much data can I get in one run? A single run can return tens of thousands of studies. Set maxStudies to 0 to capture everything matching your filters, up to the full ~585,000-study database.

How do I find recruiting clinical trials for a specific disease? Set condition to your disease and overallStatus to RECRUITING, then export every matching study — with sites, eligibility and sponsor — to CSV or JSON.

Can I pull all clinical trials by a specific pharma sponsor? Yes. Put the company in the sponsor field, for example pfizer or moderna, to export that sponsor's full trial pipeline across every phase and status.

Is it legal to use this data? ClinicalTrials.gov study records are public information published by the US National Library of Medicine. Use the data responsibly and in line with ClinicalTrials.gov terms. See the Legal note below.

What output formats are supported? JSON, CSV, Excel (XLSX), XML and JSONLines — available through the Apify dataset and API.
