Study of Safety, Efficacy and Tolerability of Secukinumab Versus Placebo, in Combination With SoC Therapy, in Patients With Active Lupus Nephritis

The study consisted of the following parts: * Screening (up to 42 days/6 weeks) * Run-in period (optional): For subjects who received Mycophenolic acid (MPA) as SoC induction therapy as per investigator's decision and who were not already on MPA at Screening, MPA dosing was initiated during a run-in period before Randomization (for up to 4 weeks prior to the first dose of secukinumab) * Treatment Period: Duration of 104 weeks of treatment with secukinumab/placebo in addition to SoC treatment (with last dose given at Week 100) * Secukinumab dosing was started with initial dosing of 300 mg s.c. injections at Baseline, Weeks 1, 2, 3, and 4, followed by dosing every 4 weeks * Follow-up period: Duration of 8 weeks (last visit performed 12 weeks after last dose of study medication) for all except for subjects entering extension study CAIN457Q12301E1 (NCT05232864). A total of 275 subjects were enrolled and were randomized to secukinumab 300 mg (n = 137) or placebo (n = 138) until study termination. Recruitment in this study was stopped on 26-May-2023. The CAIN457Q12301 study was terminated early by Novartis due to futile results from interim analysis 1 (IA1). There was no safety related reasons for early termination or concerns for the subjects in the study. The decision was made to terminate both the core and the related extension study in view of treatment futility of the core study.
