restore me -- rct of oxaloacetate on improving fatigue in me/cfs

Conditions: Myalgic Encephalomyelitis; Chronic Fatigue Syndrome; Fatigue

Summary: there is no approved treatment for fatigue in myalgic encephalomyelitis/chronic fatigue syndrome (me/cfs), a condition with as many as 2.5 million people in the us. initial case studies have shown an improvement in fatigue in me/cfs with anhydrous enol-oxaloacetate (aeo). this randomized, double blinded, placebo controlled trial will seek to further evaluate the efficacy of aeo to reduce fatigue in me/cfs, based on change in the chalder fatigue score (likert scoring) of the aeo group against the placebo group at 90 days. as secondary evaluations on other core me/cfs symptoms, the investigators are measuring the health related quality of life as assessed by the sf-36, hours of upright activity, functional capacity (activity, steps, cognition, and heart rate variability), and general health status (global change, vitals) finally, this test will gain preliminary insights on the safety, tolerability, and efficacy of aeo in me/cfs patients.

anhydrous enol-oxaloacetate is a patented thermally stabilized oxaloacetate compound with a multiple year stability rating that when ingested forms bioidentical oxaloacetate. oxaloacetate is a human metabolite involved in many biochemical reactions in the cytosol and mitochondrial, and is key to energy production. the investigators will conduct a randomized double blind placebo control trial to determine the effects of aeo on improving fatigue in me/cfs. the primary measurement with be the chalder fatigue score. the trial will be performed at one site, the bateman horne center, which specializes in the treatment of me/cfs. the trial will also evaluate the effect of aeo on other core me/cfs symptoms, health related quality of life as assessed by the sf-36, hours of upright activity, functional capacity (upright activity, steps, cognition, and heart rate variability) and general health status (global change, vitals). the trial will also gain preliminary insights on the safety, tolerability, and efficacy of aeo in me/cfs patients. treatment in the trial will be over a 90-day period for each patient. participants will be primarily recruited from bateman horne's current patients and bhcs databases of research participants. participants will be screened by telephone for potential eligibility, and if eligible, will be invited to an in person visit at bateman horne center to further confirm eligibility and obtain informed consent. evaluation will include assessment of vital signs, weight, determination of 5-minute a standard 12-lead electrocardiogram to determine heart rate variability (hrv), cognitive testing, and collection of a fasting blood. women who could potentially be pregnant will undergo pregnancy testing. participants will complete baseline questionnaires that assess me/cfs symptoms, and will undergo cognitive testing, along with a blood draw for biobanking for future banking and eventual metabolomic testing that could include assays such as metabolomics, lipidomics and transcriptomics. subjects will be provided with a device to wear on their ankle that will determine daily steps and upright activity. on visit 1 participants will receive two bottles of 90-day supply of the study capsules treatment and will be instructed to take two 500 mg capsule at breakfast and again at lunch. when participants return for visit 2, they will bring the bottles of study product with them. bhc will take account of the initial 4-week supplies of the product remaining and provide the participant with another bottle of product. when participants return for study dietary supplement will be distributed at visit 2 and visit 3, they will bring the bottles of study project with them, bhc will take account of the remaining product and provide the participant with another bottle. for the final visit 4, participant will bring the bottles of study product with them and bhc will take account of remaining study product. participants will be contacted once every two weeks by the study coordinator to assess for any side effects or difficulty taking the study dietary supplement. they will be asked to return for an in person visit every 4 weeks for 90 days at which time any symptoms or toxicities will be formally documented, and they will complete follow-up questionnaires to assess symptoms, cognition, and heart rate variability. after 12 weeks there will be a final in person visit with a final physical examination, 5-minute hrvekg, cognitive testing, and symptom assessment.

Eligibility criteria:
