Clinical Trials Aggregator (ClinicalTrials.gov)

Search ClinicalTrials.gov — the official U.S. registry of clinical studies — and get back clean, unified JSON: recruitment status, phase, sponsor, conditions, enrollment, countries and a direct study link. Filter by condition, free-text term and recruitment status.

No API key, no scraping. ClinicalTrials.gov's v2 API is official, public and keyless. This actor adds the part the raw API doesn't: normalization. The raw v2 response is deeply nested (protocolSection with many modules); this actor flattens each study to one predictable record.

What you get — one record per study

Input

Field	Type	Example	Meaning
condition	string	"breast cancer"	Disease/condition to search.
term	string	"pembrolizumab"	Extra free-text (drug, sponsor, intervention).
statuses	list	["RECRUITING"]	Recruitment status filter. Empty = all.
maxResults	int	50	Max studies (1–100).

Who this is for

• Pharma / biotech competitive and pipeline intelligence.
• CROs & recruiters finding active trials by condition and country.
• Investors / analysts tracking sponsors and phases.
• Patient-advocacy / researchers monitoring the field.

Why not use the raw API?

The v2 response nests every field under protocolSection modules. This actor picks the fields that matter and returns a stable, flat schema that drops into a spreadsheet, CRM or database.

Pricing

Billed per returned study (pay-per-event). Set your price in the Apify Console.

Legal

Uses only the official, public ClinicalTrials.gov v2 API. No login-gated data, no scraping circumvention.

Developer notes

The fetch + normalize core is in src/ct_source.py with no Apify SDK dependency:

$python -m src.ct_source

The actor wrapper (src/main.py) adds Apify input handling and dataset push.

Who uses this

• Patient recruitment companies — find recruiting studies for a condition and country before competitors do.
• Pharma / biotech competitive intelligence — track a rival's trials by sponsor, phase and status.
• Medical writers & researchers — export a clean CSV of studies for a review, no manual copy-paste.
• HealthTech products — feed a "find a trial" feature with normalized JSON.

Pricing — pay only for what you get

This actor uses Apify's pay-per-event model: you pay $3 per 1,000 results (plus a negligible $0.00005 per start). No subscription, no minimum.

Concretely: pulling 100 recruiting studies for one condition costs about $0.30 — a fraction of one hour of manual searching.

Tip: start with maxResults: 10 to see the data shape for ~$0.03, then scale up.

Quick start

1. Click Try for free (Apify gives new accounts free usage credit).
2. Adjust the input (defaults already work) and press Start.
3. When the run finishes, open the Dataset tab and export as JSON, CSV or Excel — or fetch it via the Apify API on a schedule.
