Novartis reports sustained ianalumab benefits in Sjögren’s disease study

Novartis presented interim NEPTUNUS extension data at the American College of Rheumatology Convergence 2026 on November 10, showing continued improvement in Sjögren’s disease activity through Week 108. In the group receiving ianalumab 300 mg monthly throughout, the mean ESSDAI reduction from core-study baseline reached 7.5 points, while low disease activity increased to 65.1% from 57.1% at Week 48. Participants moved from placebo to monthly ianalumab also improved, with low disease activity reaching 60.9%; safety follow-up through Week 204 identified no additional findings, according to Novartis.

The data provide longer-term efficacy and safety information for investors assessing ianalumab ahead of a U.S. Food and Drug Administration decision expected this year. A decision would determine whether the investigational therapy can enter the U.S. market for Sjögren’s disease.
