Remote Ischemic Conditioning in PPMS (NCT06171334)
Open-label, Single-center, Single-arm Futility Trial Evaluating Daily Remote Ischemic Conditioning for Reducing Progression of Disability in Patients With Primary Progressive Multiple Sclerosis (PPMS)
🩺 Plain-English Summary (8th-Grade Level)
Progressive MS remains the most difficult therapeutic challenge. Remyelination is a promising therapeutic strategy but an effective pharmacologic intervention remains elusive. Remote ischemic conditioning (RIC) is a non-pharmacologic intervention that has been studied in the context of stroke, where transient limb ischemia leads to neuroprotection. However, RIC has not yet been studied in MS. The investigators hypothesized that repeating RIC over several days may induce molecular/cellular changes in the CNS that promote remyelination. Since RIC is safe, tolerable and ready for clinical translation (recent stroke trials have shown promise), the investigators will run a clinical study to test RIC in people with primary progressive MS. The purpose of this clinical trial is to determine if RIC in a dose of 4 cycles daily can prevent worsening of walking ability in people PPMS. The trial is funded through MS Canada as well as a private donation to the Hotchkiss Brain Institute MS Translational Clinical Trials Research Program and the University of Calgary. There is no sponsorship from the pharmaceutical industry.
