This is a 56-week (24-week randomized double-blind period, 24-week active treatment period, and 8-week safety follow-up period) multicenter, randomized, double-blind, placebo-controlled, dose-ranging study to evaluate the efficacy and safety of abiprubart in participants with Sjögren's Disease with moderate or high systemic disease activity according to the European League Against Rheumatism (EULAR) Sjögren's Syndrome Disease Activity Index (ESSDAI). The objectives of the study are to evaluate efficacy, safety, pharmacokinetics (PK), and pharmacodynamics (PD) of abiprubart compared with placebo across the estimated therapeutic range using different dosing regimens of abiprubart.
