About Clinical Trial Compass

Why this exists

There are over 500,000 clinical trials registered worldwide. The data is public. The interfaces to access it are, to put it charitably, not built for patients.

Clinical Trial Compass is a consumer-grade interface on top of the world's open trial registries and drug safety databases — built for the person who has just received a diagnosis, the caregiver researching options, and anyone who wants to understand what's actually happening in medical research.

Data sources

• ClinicalTrials.gov API v2

  U.S. National Library of Medicine — the world's largest clinical trials registry. Updated daily.

• FDA FAERS (Adverse Event Reporting System)

  Real-world adverse event reports submitted by patients, clinicians, and manufacturers. Not the same as clinical trial safety data.

• OpenFDA Drug Label API

  FDA-approved drug labeling including indications, warnings, and contraindications.

What this is not

This is not medical advice. Nothing here should replace a conversation with your doctor, oncologist, or specialist. We surface data — we don't interpret it for your specific situation.

Adverse event reports in FAERS are voluntary and unverified. A high report count for a drug does not mean it is more dangerous than a drug with fewer reports — it may simply be more widely prescribed.

Business model

The core platform is free, forever. We don't accept pharma advertising, sponsored placements, or paid trial promotion. We don't sell your search data.

A premium tier is in development: personalised condition dashboards, trial match alerts, and downloadable safety reports for clinical conversations.
