ClinicalTrials.gov Scraper — Trials, Phases & Sponsors

What this Actor scrapes

ClinicalTrials.gov holds the registry every pharma, CRO and biotech competitive-intel team works from, and its API v2 returns deeply nested JSON that is painful to flatten by hand. This Actor wraps it with a plain input form and hands back one flat row per trial, so you can pull a therapeutic-area landscape into a spreadsheet without writing a parser.

What we handle for you

• 🛡️ Browser fingerprint rotation — the target sees a real browser TLS handshake, not a script.
• 🌐 Proxy rotation — fresh exit on every block through Apify Proxy.
• 🔁 Retries with backoff — 408 / 429 / 5xx retried up to five times, Retry-After honoured.
• 🧊 Clean, typed rows — schema-validated output with ISO-8601 timestamps.
• 💰 Pay per result — no data, no result charge.

Use cases

• Map the competitive landscape for a therapeutic area before a portfolio review.
• Track which sponsors are recruiting for a condition, and where.
• Build a site-selection shortlist from countries already running comparable trials.
• Monitor status changes on a watchlist of trials without checking the registry by hand.

Input

Paste this into the Apify Console, or send it as the run input over the API. Proxy settings are on by default; you rarely need to touch them.

{
  "condition": "type 2 diabetes",
  "maxResults": 3,
  "proxyConfiguration": {
    "useApifyProxy": false
  }
}

Output

One row per result, schema-validated before it is written. Export JSON, CSV, Excel or XML from the run, or read it over the API.

Pricing

You pay only for results that land. Cap any run with maxTotalChargeUsd. See pricing & billing for worked examples.

Limitations

• Returns registry data only — it does not scrape linked publications or results tables.
• Date fields are passed through exactly as the registry publishes them, which may be a month (2026-03) rather than a full date.
