How to read this list. Trials are grouped first by recruitment status, then by phase (later phases first). Each card shows the registry ID, sponsor, intervention(s) tested, planned start and primary-completion dates and target enrollment, plus a short summary trimmed from the registry description. Our extract does not include site locations or eligibility criteria, so open the record to see where a study enrols, who qualifies and whom to contact.

Frequently asked questions

How do I join a clinical trial?

Open the trial's ClinicalTrials.gov record (the "View on ClinicalTrials.gov" button), read the Eligibility Criteria and Contacts and Locations sections, and contact the study team listed there. Trials only enrol at the sites shown in the record, so check whether a site is near you or whether the study is remote/decentralised. Your own clinician can help you judge whether a trial is a sensible option and may need to provide medical records.

What do the trial phases mean?

Early Phase 1 / Phase 1 studies test safety and dosing in a small group. Phase 2 studies look for a signal of benefit in a larger group and keep checking safety. Phase 3 studies are large confirmatory trials designed to show whether a treatment works well enough for approval. Phase 4 studies follow approved treatments after they reach the market. "Phase not applicable" is used by the registry for behavioural, device, rehabilitation and other non-drug interventions.

What is the difference between recruiting, not yet recruiting and enrolling by invitation?

Recruiting means the study is actively enrolling participants. Not yet recruiting means the study is registered but has not opened enrolment; you can often register interest with the contact listed. Enrolling by invitation means participants are selected from a pre-defined group (for example an existing cohort) and the public generally cannot volunteer.

Does the Open Source Medicine Foundation run these trials?

No. OSMF does not sponsor, run or recruit for any trial on this page. We compile public registry entries from ClinicalTrials.gov so patients and clinicians can find them in one place. For questions about a specific study, contact the sponsor or study team listed on its ClinicalTrials.gov record.

How often is this list updated?

The underlying dataset is rebuilt automatically from the ClinicalTrials.gov API and these pages are regenerated from it. The date at the top of the page is the last successful refresh. Registry entries can lag the real-world status of a study, so a trial shown as recruiting may already be full.

Why is a trial I know about missing?

Our search targets interventional studies whose registered conditions map to Long COVID / PASC, ME/CFS or overlapping post-viral syndromes. Observational studies, trials registered only on non-US registries (EU CTR, ISRCTN, ANZCTR, etc.), and trials whose condition terms did not match our mapping are not included. The full ClinicalTrials.gov search is always more complete than any curated index.
