Not medical advice. This website is not medical advice, a diagnosis, a match to a trial, or a recommendation to join a study. Listings are plain-English rewrites of public ClinicalTrials.gov records. Whether a site is still enrolling, and whether you qualify, can only be confirmed by the study team and your clinician. Source registry: ClinicalTrials.gov. Editorial rules: methodology.

About the operator

PlainTrials is a registry-rewriting project, not a clinic.

Google treats health pages as YMYL. That requires a named operator, a method, and a limit on what we claim. This page is that statement.

Who runs this

PlainTrials is operated as an open-data engineering project. We parse the public ClinicalTrials.gov API, store NCT identifiers as primary keys, and publish constrained plain-English cards plus a downloadable JSON catalog. We are not a hospital, IRB, CRO, sponsor, or licensed medical publisher. We do not enroll patients or practice medicine.

Expertise we actually have, and will be judged on: ClinicalTrials.gov API v2, registry field mapping, deterministic parsing of eligibility blocks, sitemap freshness, and refusing generative text that is not grounded in the source record. Expertise we do not claim: diagnosing you, ranking treatments, or deciding whether you qualify for a trial.

Mission

ClinicalTrials.gov is the official US registry. Patients still land on protocol-speak. Our mission is to make that public record readable without replacing it. Every card must send you back to the NCT record.

Data management principles

  1. If a field is not on ClinicalTrials.gov, it is not in the product.
  2. NCT ID is the primary key. We do not invent studies.
  3. Rules parse first. A language model, if used, runs at temperature 0 and is dropped if it adds a noun that is not in the source.
  4. Contacts are only those the sponsor published on the registry.
  5. The catalog is regenerated on a schedule from the live API. lastmod in sitemap.xml follows that ingest.
  6. Corrections: if our rewrite disagrees with the NCT record, the NCT record wins. File an issue on the public repo or re-run ingest.

Nothing on PlainTrials is medical advice, a diagnosis, a referral, or a promise a site is still enrolling. Talk to the study team listed on ClinicalTrials.gov and to your clinician.
