What this phase means
This study does not use the classic phase 1–4 drug ladder. It may be a device, a behavior program, a surgery timing study, or an early feasibility test.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Measurement of oxyhemoglobin and deoxyhemoglobin concentration pre and post- exercise at baseline and Week 12. Measurement of time to recovery of oxyhemglobin post-exercise at baseline and at Week 12., or Blood draw. The registry lists allocation as na. After completion of the Baseline study visit for the main study (MUSCLE UP-PH), participants at the University of Pennsylvania location will be invited to participate in an optional substudy.
They plan to enroll about 20 people at Philadelphia. Taking part typically means using or being fitted with a device plus check-ins.
