The purpose of this study is to see if a new medicine named BMS- 986165 will treat kidney inflammation caused by lupus (lupus nephritis). This study is a clinical trial—which is how new medicines are studied before they are approved by the FDA. This particular drug targets the JAK/STAT pathway to reduce autoimmunity and inflammation.

Lupus is an autoimmune disease, which means that your immune system not only attacks bacteria and viruses but also attacks your healthy cells and organs, affecting many parts of the body. Lupus can cause fever, joint pain, rash, sensitivity of the skin to sunlight, as well as other symptoms, and may lead to inflammation and organ damage.

Current treatments for lupus are mainly drugs that suppress the immune system such as cortisone-like drugs (for example prednisone) and cyclophosphamide (a potent drug sometimes used in treating certain types of cancer), and drugs commonly used to treat or prevent malaria (called antimalarials) such as hydroxychloroquine. Many of these treatments may have serious side effects if used for a long time.

Therefore, there is a need for new and effective treatments for lupus.

The purpose of this research study is to measure how well and how safe BMS-986165 is in treating patients with Systemic Lupus Erythematosus (SLE) and to determine the optimal dose level.
