About our content

Research.Patient.info is an information service. We don't run clinical trials and we don't recruit participants on behalf of sponsors. We surface what's already published on public trial registries and explain it in plain English so patients and carers can make informed decisions with their own doctor.

Where the trial data comes from

  • ClinicalTrials.gov (US National Library of Medicine) — the world's largest public trial registry.
  • ISRCTN registry — the UK / EU primary registry, run by BioMed Central.
  • EU Clinical Trials Register — trials authorised under the EU Clinical Trials Regulation.
  • WHO ICTRP — the World Health Organization's network of national registries (planned).

We refresh data daily. Each trial page shows when we last fetched it. If a trial status changes (recruitment closes, study withdrawn, etc.) we pick that up on the next sync — but please always confirm with the trial team before travelling.

How we write plain-English summaries

The official eligibility criteria, study design and risk information are written for clinicians. We use AI to draft a plain-English version, then a clinically trained editor reviews and approves it before it is marked as reviewed on the page. Summaries that haven't been editor-reviewed are clearly labelled.

Plain-English summaries are never a substitute for the official trial documentation, the patient information sheet, or a conversation with your own doctor. Always read the official documents and discuss before taking part.

What we are not

  • We are not affiliated with the MHRA, HRA, NHS, NIHR, FDA or any regulator.
  • We don't sponsor, run, fund or vet the trials we list.
  • Inclusion on this site is not an endorsement.
  • We don't provide medical advice, diagnosis or treatment.
