lift: life improvement trial

Conditions: ME/CFS

Summary: the lift will be conducted at brigham and women's hospital (bwh) of harvard medical school, focusing on the effect of pyridostigmine (mestinon) and low-dose naltrexone (ldn) in subjects aged 18-65 meeting the canadian consensus criteria (ccc) for myalgic encephalomyelitis/chronic fatigue syndrome (me/cfs) as well as having specifically orthostatic intolerance. this double-blind, placebo-controlled study will involve 160 participants randomized into one of four possible groups: pyridostigmine/ldn (40), pyridostigmine/placebo (40), ldn/placebo (40), placebo/placebo (40). the dose of pyridostigmine will be carefully titrated from 30mg to 60mg three times a day, and the dose of ldn will be titrated from 1.5 mg to 4.5 mg once daily. the trial includes a scale-back plan, allowing participants to reduce their dosage if they experience intolerance symptoms, with adjustments made during weekly visits. this plan provides a personalized approach to medication tolerance, ensuring participant's safety and comfort throughout the trial. the time commitment for the participant is approximately three (3) months, and during this time, there will be three (3) in-person visits to bwh and four (4) virtual visits. study procedures will include two (2) submaximum cardiopulmonary exercise tests, questionnaires (virtually completed), and blood and urine collection. we will be recruiting from the bwh dyspnea clinic as well as the open medicine foundation (omf) studyme registry and anticipate the entire trial will take two (2) years to complete. the lift represents a significant endeavor to improve treatment options for me/cfs patients and contribute to the broader understanding of this debilitating condition.
