A Phase 2, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Obexelimab in Patients With Systemic Lupus Erythematosus

What this Trial Is About

Researchers are evaluating the efficacy and safety of obexelimab in adults with systemic lupus erythematosus SLE, a chronic autoimmune disease. This phase 2, randomized, double-blind study includes participants diagnosed with SLE for at least 24 weeks who meet specific disease activity criteria based on established lupus assessment scores. The study is sponsored by Zenas BioPharma USA, LLC and aims to better understand how obexelimab affects lupus symptoms and immune activity. The study involves a 24-week treatment period where participants receive either obexelimab or a placebo through weekly subcutaneous injections. Prior to treatment, a screening period up to 28 days confirms eligibility. After the treatment period, there is a 12-week follow-up phase. All participants continue their standard lupus care with nonbiologic therapies such as corticosteroids, antimalarials, or immunosuppressants. Scheduled visits occur at weeks 2, 4, and every 4 weeks thereafter during the treatment phase. During the study, participants will undergo assessments for lupus disease activity, safety, drug levels, immune responses, and potential side effects. These evaluations include clinical exams and laboratory tests at regular visits. The total duration of participation can last up to approximately 40 weeks, covering screening, treatment, and follow-up. Researchers will review primary and secondary outcome measures to assess the impact of obexelimab on lupus activity and patient health throughout the study.
