Participant Flow
This is a platform study record. Study recruitment period was from late July 2023 to mid-August 2024 at 69 US sites. Recruiting centers were a mix of large academic and small independent research sites in rural and urban, outpatient settings.
Consented participants were required to endorse two moderate or one severe symptom in one of 3 symptom clusters (exercise intolerance, autonomic dysfunction, or cognitive dysfunction), then meet or exceed a minimal score on a symptom specific questionnaire prior to being assigned. In addition to platform protocol inclusion and exclusion, participants had to meet no symptom cluster exclusion criteria and meet all drug appendix inclusion criteria and no drug appendix exclusion criteria.
