Evaluation of Efficacy and Safety of Rituximab and Mycophenolate Mofetil Combination in Patients With Interstitial Lung Disease Related to Systemic Sclerosis

Официальное название

Evaluation of Efficacy and Safety of Rituximab and Mycophenolate Mofetil Combination in Patients With Interstitial Lung Disease Related to Systemic Sclerosis: a Multicentre Double-blind Placebo-controlled Randomized Trial.

Обзор

The goal of this clinical trial is to evaluate the efficacy on lung function after 24 weeks of rituximab + MMF combination comparatively to placebo + MMF combination in patients with SSc-ILD severe at the initial assessment or at high risk of progression.
