ClinicalTrials.gov Study Scraper

What it does

This actor scrapes clinical trial study records from the ClinicalTrials.gov API v2. It retrieves comprehensive study information including trial identification, status, conditions being studied, interventions, phases, and enrollment data. The actor uses cursor-based pagination to efficiently navigate large result sets and handles all API interaction automatically.

Why use this actor

This actor provides a simple, reliable, and scalable way to extract data from public APIs without needing to write any code or manage infrastructure. It handles pagination, rate limiting, error recovery, and data normalization automatically. Whether you are a researcher, analyst, or developer, this actor saves you hours of manual data collection work. The structured JSON output integrates seamlessly with spreadsheets, databases, dashboards, and downstream data pipelines. Run it on Apify platform for automatic scheduling, monitoring, and proxy management.

Input parameters

• searchQuery (string, required): Medical condition, drug name, or keyword to search. Default: "diabetes".
• maxResults (integer, optional): Maximum number of study records to return. Range: 1-1000. Default: 100.

Output data

The actor outputs a dataset with the following fields:

• nctId: ClinicalTrials.gov identifier (e.g., NCT05012345)
• title: Brief title of the clinical trial
• status: Overall recruitment status
• conditions: Comma-separated list of conditions studied
• interventions: Comma-separated list of intervention names
• startDate: Study start date
• phases: Trial phases (e.g., Phase 1, Phase 2)
• enrollment: Number of participants enrolled

Each record is validated and null-checked before being pushed to the dataset. Missing or unavailable fields are set to null rather than being omitted, ensuring consistent schema across all records.

Example output

[
    {
        "nctId": "NCT05012345",
        "title": "Study of Drug X for Type 2 Diabetes",
        "status": "RECRUITING",
        "conditions": "Type 2 Diabetes Mellitus",
        "interventions": "Drug X, Placebo",
        "startDate": "2024-03-15",
        "phases": "PHASE2",
        "enrollment": 250
    }
]

Pricing

This actor is priced based on usage:

• $0.01 per result returned in the dataset
• $0.005 per actor start (flat fee per run)

These costs cover Apify platform compute and proxy resources. For large-scale scraping jobs, consider using the maxResults parameter to control costs and stay within your budget. Typical runs of 100 results cost approximately $1.01.
