A Study of MT-0551 in Patients With Systemic Sclerosis
September 11, 2023 updated by: Mitsubishi Tanabe Pharma Corporation
Phase 3 Study of MT-0551 in Patients With Systemic Sclerosis (Placebo-Controlled Double-Blind Study)
The study will verify the superiority of MT-0551 to placebo at 26 weeks after treatment initiation in systemic sclerosis (SSc) patients using the modified Rodnan Total Skin thickness Score (mRTSS) as a measure of skin thickening.
The safety and pharmacokinetics will also be investigated.
