Effectiveness and Safety of SAR156597 in Treating Diffuse Systemic Sclerosis
a study on Systemic Sclerosis
Primary Objective: To evaluate, in comparison with placebo, the efficacy of SAR156597 administered subcutaneously for 24 weeks on skin fibrosis in patients with dcSSc. Secondary Objectives: - To evaluate the efficacy of SAR156597 compared to placebo on physical/functional disability in patients with dcSSc. - To evaluate the efficacy of SAR156597 compared to placebo on respiratory function in patients with dcSSc. - To evaluate the safety profile of SAR156597 compared to placebo in patients with dcSSc. - To evaluate the potential for immunogenicity (anti-drug antibodies [ADA] response) of SAR156597 in patients with dcSSc. - To evaluate the pharmacokinetics (PK) (trough plasma concentrations) of SAR156597 administered subcutaneously for 24 weeks.
Efficacy and Safety of SAR156597 in the Treatment of Diffuse Cutaneous Systemic Sclerosis (dcSSc): A Randomized, Double-blind, Placebo-controlled, 24-week, Proof of Concept Study
The total study duration per patient will be 39 weeks; consisting of a 4-week screening, a 24-week of study treatment period, and a 11-week follow-up with no study drug treatment.
