The Purpose of This Study is to Evaluate the Efficacy and Safety of 626 in the Treatment of SLE

This study will evaluate the effect and safety of 626 in patients with SLE

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease with heterogeneous manifestations and disease course. Despite advances in medical care, there are still significant unmet needs in SLE with persistent disease activity, disease flares, intolerance to standard of care (SOC) therapies, and development of organ damage and co-morbidities. The purpose of this study is to demonstrate the clinical efficacy and safety of 626 added to standard of care (SoC) therapy compared to placebo with SoC therapy in subjects with SLE.
