- To assess the efficacy of Afimetoran versus placebo using an alternative composite measure of improvement in lupus activity that is primarily driven by the British Isles Lupus Assessment Group (BILAG), in participants in active SLE - To assess the efficacy of Afimetoran versus placebo on measures of global and organ-specific clinical response in participants with active SLE - To assess the steroid-sparing effect of Afimetoran versus placebo in participants with active SLE - To characterize patient-reported health status in participants with active SLE on Afimetoran - To assess the safety and tolerability of Afimetoran versus placebo in participants with active SLE |

Other protocol-defined inclusion criteria apply. |
|
E.4 | Principal exclusion criteria |
- Active severe lupus nephritis (LN) as assessed by the investigator - Active or unstable neuropsychiatric lupus manifestations defined by the Hybrid SLEDAI - Diagnosis of Mixed Connective Tissue Disease for which the predominant diagnosis is not SLE - Antiphospholipid Syndrome

Other protocol-defined exclusion criteria apply. |
