A Phase 2 Study to Evaluate the Safety and Efficacy of LOU064 in Patients With Moderate to Severe Sjögren's Syndrome

This study was planned as an adaptive Phase 2 randomized, double-blind, placebo-controlled, multi-center, integrated dose-ranging study to evaluate the safety and efficacy of multiple remibrutinib doses in patients with moderate to severe Sjögren's Syndrome. Of the initially planned two parts, only Part 1 of the study was conducted. In Part 1, the highest expected biologically active single dose of remibrutinib (100 mg) was tested in two different dosing regimens, a once daily dose (qd) or twice daily dose (bid), and compared to the placebo group. Each patient in Part 1 of the study underwent a screening period of up to 6 weeks, a treatment period of 24 weeks, and a follow-up period of 30 days post-treatment before the End of Study (EOS) visit. The total duration for each patient in the study, including Screening, was up to 35 weeks. For the treatment period, patients were randomized in a 1:1:1 ratio to one of the 3 treatment groups: remibrutinib 100 mg bid, remibrutinib 100 mg qd and placebo.
