Study Endpoints
Primary Endpoints
Percentage of Participants Who Achieved a ≥4 Point Reduction in Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) 2000 (2K) Score at Week 24
Week 24

Percentage of Participants who Achieved a ≥4 Point Reduction in SLEDAI-2K Score at Week 24. A SLEDAI-4 response is defined as a ≥4-point reduction in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score from baseline. The SLEDAI-2K score range is from a minimum of 0 to a maximum of 105 (higher scores represent higher disease activity).

Safety and Tolerability of LY3471851 - Number of Participants Experiencing Adverse Events
Informed consent until last study visit (approximately 79 days after first dose of study drug)

Safety and tolerability of LY3471851 as assessed through collection of adverse events, serious adverse events, change in vital signs (body temperature, blood pressure, heart rate, rate of breathing and oxygen in blood); electrocardiograms (ECG); laboratory evaluations (hematology, chemistry, liver function and urine analysis).
