Study Endpoints
Primary Endpoints
Number of participants with a 70% reduction relative to baseline in the Cutaneous Lupus Erythematosus Disease Area and Severity Index-Activity (CLASI-A) score
At Week 24

The CLASI is a validated index used for assessing the cutaneous lesions of SLE. It consists of 2 separate scores: i) activity of the disease, and ii) measure of damage. The CLASI instrument will be used at each study visit to capture individual skin manifestation scores. CLASI-70 responder (Yes/No) is defined as a participant who achieves a 70% reduction relative to baseline in CLASI-A score. Otherwise, the participant is considered a non-responder.

Secondary Endpoints
Change from baseline in total CLASI-A score
At Week 24
Number of participants with CLASI-70 response
At Week 12
Number of participants with ≥ 7-point reduction from baseline in CLASI-A total score
