This study tests cenerimod, a new oral medicine, to see if it helps adults with Systemic Lupus Erythematosus (SLE), a disease where the immune system attacks the body. Doctors want to know if cenerimod can reduce the symptoms of SLE, especially in people with moderate to severe symptoms. This study also checks if cenerimod is safe to use with other treatments. Participants will receive either cenerimod or a placebo, which is a fake pill that looks like the real medicine, but doesn’t have the active drug. This study will last for 12 months.
- Participation: About 420 adults will join the study. Half will receive cenerimod, and half will receive a placebo.
- Requirements: Participants must have been diagnosed with SLE for at least 6 months and be on stable SLE medication.
- Risks: Pregnant women or those with severe heart or lung conditions cannot participate.
Participants will need regular doctor visits and tests. Women able to have children must use birth control and take pregnancy tests during and after the study.
