Nipocalimab Reduces Sjögren’s Disease Activity in Phase 2 DAHLIAS Trial
The Phase 2 DAHLIAS study (NCT04968912), a multicenter, randomized, placebo-controlled, double-blind trial, evaluated nipocalimab—an investigational monoclonal antibody targeting the neonatal Fc receptor (FcRn)—in adults aged 18–75 with moderate-to-severe primary Sjögren’s disease (SjD) seropositive for anti-Ro60 and/or anti-Ro52 IgG autoantibodies. A total of 163 participants were randomized 1:1:1 to receive intravenous nipocalimab 5 mg/kg, 15 mg/kg, or placebo every 2 weeks through Week 22, alongside standard-of-care therapy. The primary endpoint was the change from baseline in the Clinical EULAR Sjögren’s Syndrome Disease Activity Index (ClinESSDAI) score at Week 24, a composite measure assessing 11 systemic domains including constitutional symptoms, lymphadenopathy, glandular swelling, articular, cutaneous, respiratory, renal, muscular, peripheral/central nervous system, and hematological involvement.
