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).
