Trial overview
Official title: A Phase 2/3, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate The Efficacy And Safety of Belimumab Administered Subcutaneously in Adults With Systemic Sclerosis Associated Interstitial Lung Disease (SSC-ILD)
Trial description: This study investigates the efficacy and safety of belimumab compared to placebo, in addition to standard therapy, for the treatment of participants with systemic sclerosis associated interstitial lung disease (SSc-ILD). The study will evaluate the effect of belimumab treatment on lung function as well as on extra-pulmonary disease manifestations, including skin thickening and general symptoms, such as fatigue, that impact quality of life (QoL).

Inclusion and exclusion criteria
Inclusion criteria:
