Conditions

Diffuse Cutaneous Systemic Sclerosis (dcSSc)

Brief summary

Mean change from Baseline to Week 24 on the modified Rodnan skin score (mRSS) in each study arm.

Detailed description

Incidence, seriousness, and severity of AEs, TEAEs, SAEs, and treatment-related adverse events (TRAEs), Clinically significant findings on physical examination, vital signs, and clinical laboratory tests., Proportion of participants in each arm with a gene signature response on skin biopsy at Week 12., Sparse and serial PK profiles after MTX-474 administration to participants will be evaluated by population PK, based on drug concentrations in serum over time. For a subset of participants with serial PK sampling, noncompartmental PK parameters (CL, t1/2, and AUCs) will be reported.
