Study Endpoints

Primary Endpoints

Proportion of participants who achieve clinical remission at Week 12 by modified Mayo Score (mMS)
At Week 12

The Mayo score (full MS) is a composite instrument that consists of patient reported stool frequency and rectal bleeding, endoscopy-derived measures and physician-reported assessment (PGA). The modified Mayo score is calculated omitting PGA. And an endoscopy score of 1 with no friability.

Percent Change From Baseline in Cutaneous Erythematosus Disease Area and Severity Index - Activity (CLASI-A) Sub-Score at Week 12
Baseline (Day 1) and Week 12

The CLASI is a clinician rated scale designed to assess the disease activity and damage in CLE in adults. It is composed of 56 items covering 2 dimensions: the disease activity (CLASI-A) and the disease damage (CLASI-D). CLASI-A disease activity covers the domains: erythema, scale/hypertrophy, recent hair loss/alopecia, and mucous membrane lesions. CLASI-A sub-score ranges for 0 to 70, where 0-9 indicates mild disease, 10-20 indicates moderate disease, and 21-70 indicates severe disease. Higher score indicates a more severe skin disease. Baseline was defined as the Day 1 assessment value.
