A Research Trial to Assess if Cenerimod is Efficacious and Safe to Treat Active Lupus Nephritis on Top of Regular Treatment
Trial Parameters
Brief Summary
The goal of this clinical trial is to learn if cenerimod, on top of regular treatment, works to treat active lupus nephritis in adults with systemic lupus erythematosus and active lupus nephritis. It will also learn about the safety of cenerimod. The main questions it aims to answer are: * Does cenerimod improve kidney function in participants? * What medical problems do participants have when taking cenerimod? Researchers will compare cenerimod to a placebo (a look-alike substance that contains no drug) to see how well cenerimod works when it is added to regular treatment. Participants will: * Take cenerimod or a placebo every day for 76 weeks (approximately 1.5 years), on top of regular treatment. * Visit the clinic every 1 to 3 months for checkups and tests.
Eligibility Criteria
Main Inclusion Criteria: * Classification of systemic lupus erythematosus (SLE) made according to the 2019 European Alliance of Associations for Rheumatology / American College of Rheumatology (EULAR/ACR) criteria. * Renal biopsy within 6 months prior to Screening visit indicating Class III or IV active glomerulonephritis with or without co-existing Class V, OR pure Class V membranous LN. If no biopsy was performed within 6 months of Screening, a biopsy will be performed during the Screening period, after all other inclusion/exclusion criteria are verified. * Active renal disease defined as urine protein/creatinine ratio ≥ 1 mg/mg, assessed on a 24h urine collection. * eGFR ≥ 15 mL/min/1.73 m\^2. Enrollment of participants with eGFR between ≥ 15 and \< 30 mL/min/1.73 m\^2 requires: * a renal biopsy during the screening period showing sclerosis in ≤ 50% of glomeruli, * activity index ≥ 2, and chronicity index \< 4, on the National Institutes for Health 2018 activity and chronicity indic
