Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The LIFT trial investigates the effects of Pyridostigmine and Low-Dose Naltrexone on individuals aged 18-65 diagnosed with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and experiencing orthostatic intolerance. This double-blind, placebo-controlled study will enroll 160 participants who will be randomized into four groups to receive either the active medications or placebos. Dosages will be carefully adjusted based on individual tolerance, with weekly visits to monitor progress and make necessary changes. The goal is to assess the efficacy of these treatments in alleviating symptoms associated with ME/CFS.

Why it matters

Potential benefit: If successful, this trial could provide new treatment options for patients suffering from ME/CFS, potentially improving their quality of life.

How similar studies have gone: While there have been studies exploring treatments for ME/CFS, the specific combination of Pyridostigmine and Low-Dose Naltrexone in this context is relatively novel.
