Trial Outcomes & Findings for A Futility Trial of Sirolimus in Multiple System Atrophy (NCT NCT03589976)

NCT ID: NCT03589976

Last Updated: 2021-12-07

Results Overview

UMSARS is a validated, disease-specific scale representing the diverse signs and symptoms in MSA. USMARS has an Activities of Daily Living score (UMSARS-1, 12 questions) that evaluates motor including autonomic activities and the Motor Examination score (UMSARS-2, 14 questions). UMSARS-3 measures supine/standing BP and UMSARS-4 is a disability scale. The total range of score is 1-109; Higher scores on the UMSARS scales mean poorer health.

Measure
Sirolimus
2 mg/day (one 2-mg tablet/day). The dose of sirolimus will be adjusted throughout the trial based on sirolimus plasma levels and the presence of drug-related adverse events. The maximum dose of sirolimus will be6 mg/day (three 2-mg tablets/day). Sirolimus 2 MG: Dose will be adjusted throughout this trial based on sirolimus plasma levels and the presence of drug-related adverse events. The maximum dose will be 6mg/day.
Placebo
Patients receiving placebo will undergo analog sham level measurements and the number of tablets will be also adjusted to maintain the blinding of the trial. Placebo: Patients receiving placebo will undergo analog sham level measurements and the number of tablets will be also adjusted to maintain the blinding of the trial.

SECONDARY outcome

Timeframe: Baseline, 48 Weeks

The Activities of Daily Living score (UMSARS-1, 12 questions) evaluates impact of symptoms, including autonomic, on activities of daily living. 12 functional situations are rated between 0-4. The total range of score is 0-48; the higher the score, the more problems conducting activities of daily living.
