View on ClinicalTrials.gov ↗Based on pilot patient observations, and experience from the prior study KTS-1-2008, the investigators anticipate that severely affected chronic fatigue syndrome patients may benefit from B-cell depletion therapy using Rituximab induction with maintenance treatment.
View on ClinicalTrials.gov ↗Previous studies have shown that health-related quality of life (HRQoL) in adolescents living with chronic fatigue syndrome (CFS/ME) is low if compared with healthy adolescents and adolescents living with other chronic diseases. Effective strategies to improve HRQoL in this group are still lacking.
View on ClinicalTrials.gov ↗Chronic fatigue syndrome is a disabling illness for which there is no specific treatment. As a group, CFS patients have disturbed sleep with frequent arousals and the sense of not having slept upon awakening. Xyrem (Sodium oxybate) is known to improve deep sleep and so may reduce the sleep disturbances of CFS leading to better sleep with less fatigue.
View on ClinicalTrials.gov ↗The hypothesis is that a subset of patients with chronic fatigue syndrome/ myalgic encephalomyelitis (CFS/ME), including also patients with no clinical response after B-cell depletion therapy using the anti-CD20 antibody Rituximab, may benefit from tumor necrosis factor-alpha inhibition using Etanercept as weekly subcutaneous injections.
View on ClinicalTrials.gov ↗A subset of patients suffering from chronic fatigue syndrome exhibit symptoms of neurally mediated hypotension. While the underlying pathophysiology of chronic fatigue syndrome is not precisely understood, a dysfunction of the autonomic nervous system is thought to play a role in this subset of patients.

Chronic fatigue is the most common and debilitating symptom in intensive care unit (ICU) survivors. Indeed, it has been widely reported that patients who stayed in ICU for prolonged periods report a feeling of tiredness for months to years after ICU discharge. This chronic fatigue affects their quality of life by decreasing their capacity to perform simple tasks of daily life.
View on ClinicalTrials.gov ↗Chronic fatigue syndrome (CFS) is a disabling, unexplained disorder characterized by physical and mental exhaustion. Complaints of disturbed and unrefreshing sleep are very common in CFS patients, however, the relationship between (disturbed) sleep quality and fatigue is still not fully elucidated.
View on ClinicalTrials.gov ↗The main objective of this study is to test if naltrexone, when taken in low doses, has an anti-inflammatory effect that may be associated with positive clinical outcomes in people with chronic fatigue syndrome (CFS).
View on ClinicalTrials.gov ↗The pathogenesis of chronic fatigue syndrome (CFS) is poorly understood and no effective therapy has been developed. Recent studies suggest that a preceding viral infection causes mitochondrial dysfunction of the brain and skeletal muscle of genetically susceptible individuals. There is no specific laboratory test to identify patients with CFS.

Psychoneuromentalism Disorder is a disorder arising in the mind; that is related to the mental and emotional state of a person. It is the science of mental life. The body has a natural design to heal itself.
View on ClinicalTrials.gov ↗There is no cure or approved treatments for ME. Several causes have been implicated in ME, including poor mitochondrial function. Mitochondria are the powerhouse of cells, producing energy.
View on ClinicalTrials.gov ↗The present study is a randomized controlled trial (RCT) with an overall objective to examine the effect of an interdisciplinary complex intervention on the level of fatigue in lymphoma survivors with chronic fatigue.
View on ClinicalTrials.gov ↗The aim of this 16-week pilot randomized trial is to explore the potential benefit of the OTC supplement hydrogen water, for the symptoms of chronic fatigue syndrome (CFS). Methods: This 16-week home-based trial will compare two groups: (1) low dose hydrogen water (2-3 glasses/day) for all 16 weeks; and (2) low dose followed by high dose hydrogen water (up to 5 glasses/day).

View on ClinicalTrials.gov ↗Persistent physical symptoms (PPS) might diminish studying or workability and daily functioning without a clear medical or environment-related explanation. Psychosocial, patient-involving treatments that support individuals' abilities managing with the PPS and health behaviours have shown promising effects in treating PPS but the acceptability of these treatments among symptomatic individuals is low.
View on ClinicalTrials.gov ↗The aim of the study is to investigate the effects of oral melatonin and zinc supplementation on core features in individuals with ME/CFS.
View on ClinicalTrials.gov ↗The aim of this 10-week pilot study is to explore the potential benefit of two recently developed non-invasive interventions, heart rate variability biofeedback (HRV-BF) and OTC supplement hydrogen water, for the symptoms of chronic fatigue syndrome (CFS). Symptom measures and heart monitoring information will be generated by this study.
View on ClinicalTrials.gov ↗Long Covid could be much more frequent than it is thought to be. Few dwell on the great problem represented by the post covid syndrome. The virus often leaves important marks on our body, and those who recover face problems of various kinds: chronic fatigue, shortness of breath, dry cough, headache, cognitive difficulties.

In this Randomized Controlled Trial (RCT), in addition to evaluating the clinical effects of VIRTUAL SFCAMINA treatment in the short- and long term.

View on ClinicalTrials.gov ↗The Chronic Fatigue Syndrome (CFS) presents many disturbances multidimensional affect holistically to people who have the disease and current management of fatigue, pain, anxiety, depression and sleep disturbances present in this clinical entity is unsatisfactory. The hypothesis of this essay is to contrast that acupuncture is more useful than placebo.
View on ClinicalTrials.gov ↗Chronic fatigue syndrome (CFS) is a devastating and complex disorder. People with CFS experience overwhelming fatigue and a host of other symptoms that are not improved by bed rest. Interestingly, many of the symptoms experienced by people with CFS are identical to symptoms caused by long-term low-level exposure to mercury, which is called micromercurialism.
View on ClinicalTrials.gov ↗Postcancer fatigue is a severe and invalidating problem, impairing quality of life. About 20 to 40% of the patients remain fatigued, at least one year after successful cancer treatment. Fortunately, there is an effective treatment for postcancer fatigue; cognitive behavior therapy.

CSS are characterized by an increased responsiveness of central pain neurons. An impaired endogenous pain inhibition is already demonstrated in CSS.
View on ClinicalTrials.gov ↗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.
We summarise newly registered post-viral trials and notable results on the OSMF Substack.
