Every interventional study for myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) in our ClinicalTrials.gov extract, regardless of status. Use this page to answer "has X been trialled in ME/CFS?": search the page (Ctrl/Cmd-F) for a drug or intervention name, or browse the by-agent index.

Trials are grouped by status. Completed, terminated and withdrawn studies are included because they are often the most informative: a terminated trial may indicate futility, safety concerns or simply funding problems, so always read the record. Only trials currently open to enrolment are shown on the recruiting page.

Status badges: green = recruiting, blue = not yet recruiting, purple = enrolling by invitation, orange = active but closed to enrolment, grey = completed, red = terminated / withdrawn / suspended. "Unknown status" means the sponsor has not updated the record for more than two years past its expected completion date.

The second goal of the study is to establish predictors of outcome. It is very important to know the characteristics of patients who will benefit from Cognitive Behavioural Treatment (CBT) and who will not.

Frequently asked questions

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.

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.

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.

What does "terminated" or "withdrawn" mean?

Terminated means the study started but stopped early, for reasons that can include lack of funding, slow recruitment, safety signals or clear futility; the record often states why. Withdrawn means the study was cancelled before enrolling anyone. Suspended means enrolment is paused and may resume.
