研究组 & 干预措施
Cenerimod 2 mg (Ex-4mg)
Half the participants that complete treatment with cenerimod 4 mg in Treatment Period 1 will be re-randomized to cenerimod 2 mg once daily in addition to background SLE therapy during Treatment Period 2. Participants will receive cenerimod 2 mg for 6 months and end study treatment at the Month 12 visit.
干预措施: cenerimod 2 mg (ex-4 mg) (Drug)
Placebo
Participants will receive placebo (matching cenerimod) once daily in addition to background SLE therapy. Treatment Period 1 is 6 months long. It will start with the administration of the first dose of study treatment, after randomization, and end at the Month 6 visit. All randomized participants need to complete Treatment Period 1 before continuing in Treatment Period 2. In Treatment Period 2 participants will continue with placebo (matching cenerimod) for a further 6 months and end study treatment at the Month 12 visit.
干预措施: Placebo (Drug)
Cenerimod 0.5 mg
Participants will receive cenerimod 0.5 mg once daily in addition to background SLE therapy. Treatment Period 1 is 6 months long. It will start with the administration of the first dose of study treatment, after randomization, and end at the Month 6 visit. All randomized participants need to complete Treatment Period 1 before continuing in Treatment Period 2. In Treatment Period 2 participants will continue with cenerimod 0.5 mg for a further 6 months and end study treatment at the Month 12 visit.

干预措施: Cenerimod 2 mg (Drug)
Cenerimod 4 mg
Participants will received cenerimod 4 mg once daily in addition to background SLE therapy for up to 6 months in Treatment Period 1. The participants randomized to the 4 mg treatment who were still on treatment at Month 6 were re-randomized in a 1:1 ratio to placebo or cenerimod 2 mg to enter Treatment Period 2. The participants who did not complete 6 months of cenerimod 4 mg treatment will be analyzed in the "Non Re-randomized (Ex-4mg)" treatment group.

结局指标
主要结局
Change From Baseline to Month 6 in the Modified Systemic Lupus Erythematosus Activity Index 2000 (mSLEDAI-2K) Score
时间窗: Baseline (Day 1) and Month 6
The primary endpoint is the absolute change from baseline in the modified Systemic Lupus Erythematosus Activity Index 2000 (mSLEDAI-2K) score. The SLEDAI-2K is a cumulative index of lupus disease activity scored by the physician. It is calculated from 24 individual descriptors across 9 organ systems, with weighted scores of 2-8, and measures disease activity within the last 10 days. 0 points indicates inactive disease, and 105 points is the maximum possible score. In this study the SLEDAI-2K was modified, to exclude leucopenia (minus 1 point), due to the mechanism of action of cenerimod. Improvement in systemic lupus erythematosus disease activity is defined as a reduction in SLEDAI-2K score of greater than or equal to 4. A decreased score, i.e., a negative change, indicates an improvement in systemic lupus erythematosus disease activity from baseline to Month 6.
