Brief Summary:
The reason for this study is to see if the study drug LY3471851 (NKTR-358) is safe and effective in adults with systemic lupus erythematosus (SLE).

Condition or disease Intervention/treatment Phase
Systemic Lupus Erythematosus Drug: LY3471851 Drug: Placebo Phase 2

Detailed Description:
LY3471851 is a potential first-in-class therapeutic that may address an underlying immune system imbalance in people with many autoimmune conditions. It targets the interleukin (IL-2) receptor complex in the body in order to stimulate proliferation of inhibitory immune cells known as regulatory T cells. By activating these cells, LY3471851 may act to bring the immune system back into balance.
