A Phase 3 Study of TAS-205 in Patients With Duchenne Muscular Dystrophy(REACH-DMD)

Phase 3
Active, not recruiting
Conditions
Duchenne Muscular Dystrophy
Interventions
Drug: TAS-205 [Ambulatory Cohort] [Non-ambulatory Cohort]
Drug: Placebo [Ambulatory Cohort] only
Registration Number
NCT04587908
Lead Sponsor
Taiho Pharmaceutical Co., Ltd.
Brief Summary

The purpose of this study is to evaluate the efficacy and safety of TAS-205 in patients with Duchenne muscular dystrophy

Detailed Description

\[Ambulatory Cohort\] The main purpose of this cohort is to assess the efficacy of TAS-205 in patients with Duchenne muscular dystrophy (DMD) compared with placebo as measured by the mean change from baseline to 52 weeks in the time to rise from the floor. Following completion of the treatment period, patients may elect to continue in open-label extension study.

\[Non-ambulatory Cohort\] The main purpose of this cohort is to assess the safety of TAS-205 in patients with DMD by collecting the incidence of adverse events for 52 weeks.
