Obexelimab for Systemic Lupus Erythematosus

This study is testing a drug called obexelimab to see if it is safe and effective for people with Systemic Lupus Erythematosus (SLE), a chronic autoimmune disease. Obexelimab works by targeting specific cells (B cells) that play a role in SLE. You might be able to join if you are between 18 and 70 years old, have been diagnosed with SLE for at least 24 weeks, and have active symptoms. The main goal is to see how well obexelimab works after 24 weeks of treatment. The study is currently unclear on its recruitment status and plans to enroll about 190 participants.
