A Phase 3, Multicenter, Open-label, Single-arm, Extension Study to Evaluate the Long-term Safety and Tolerability of Cenerimod in Adult Subjects With Moderate-to-Severe Systemic Lupus Erythematosus (SLE) on Top of Background Therapy

Descripción detallada

Participants who completed the 12-month double-blind treatment period (cenerimod 4 mg or placebo) in either of the parent studies, ID-064A301 or ID-064A302, are eligible to participate in this extension study. All participants in this study will receive cenerimod 4 mg for at least 12 months (1 year) and up to a maximum of 36 months (3 years). All participants may additionally receive standard of care treatment for systemic lupus erythematosus, i.e., at least 1 of the following: oral corticosteroids, antimalarial drugs, or immunosuppressant drugs. When all participants have reached at least 12 months of study treatment or have prematurely discontinued study treatment before the end of Month 12, the end-of-treatment will be scheduled for all participants who are still on study treatment. The safety follow-up period starts on the day after the last dose of study treatment and ends after 6 months with the final study visit. Thus, the maximum duration of participation is 3.5 years. Data collected in this extension study will allow an assessment of whether the safety and tolerability profile of cenerimod established in the controlled parent studies remains the same after a longer period of treatment.
