Clinical Trials Search (ClinicalTrials.gov)

Search ClinicalTrials.gov by condition, intervention, sponsor, location or free text and get flat rows: status, phases, enrollment, sponsor, dates, countries, site count, results flag.

Why use it

• Competitive landscape for a drug target or indication
• Translational sections of grant proposals
• Pipeline monitoring on a schedule

No API keys, no scraping of HTML – the actor talks to the official public API, handles paging, rate limits and retries, and returns flat JSON you can export as CSV/Excel or call from code, Make, Zapier, n8n or AI agents (Apify MCP server).

Example input:

{
  "condition": "obesity",
  "maxResults": 100
}

Output (one dataset item per result)

    "PHASE3"
  ],
  "enrollment": 240,

Use with AI agents (Apify MCP server)

Add the Apify MCP server (https://mcp.apify.com) to Claude, Cursor or any MCP client and enable this actor (researchdata/clinical-trials-search). The agent can then call it directly: describe what you need, the agent fills the input fields above, runs the actor and reads the dataset. Because results are flat JSON with explicit nulls, an agent can use them without extra parsing. Set a maximum cost per run to keep agent calls capped.

Pricing

Pay per event: $0.002 per result (trial returned). You only pay for results you get; set a max cost per run to cap spending. Higher Apify plans get automatic volume discounts: Bronze −10 %, Silver −20 %, Gold −30 %.

Cost example

At $0.002 per result: 50 results ≈ $0.10, 1,000 results ≈ $2.00. Set a maximum cost per run in the run options to cap spending.

Limits

• Data comes from the provider's public API; fields the provider does not publish are returned empty (null), never guessed.
• Results reflect the provider's database at run time.
• Not affiliated with the data provider.

FAQ

Which registry is used?
