A New Era of Targeted Therapy for Sjögren's
Sjögren's disease is a chronic autoimmune condition primarily affecting moisture-producing glands, but it can also cause widespread systemic symptoms. The current standard of care largely focuses on managing symptoms with over-the-counter and prescription products like artificial tears and saliva substitutes, as well as general immunosuppressants in some cases. This has left a significant unmet need for treatments that address the root cause of the autoimmune response. Recent advancements, however, are shifting the paradigm towards more specific, targeted therapies.
Nipocalimab: Blocking IgG Autoantibodies
Nipocalimab, an investigational monoclonal antibody from Johnson & Johnson, works by blocking the neonatal Fc receptor (FcRn). This action reduces the levels of disease-causing IgG autoantibodies that contribute to inflammation in Sjögren's.
- Regulatory Milestones: The U.S. FDA granted nipocalimab Breakthrough Therapy designation for moderate-to-severe Sjögren's in November 2024, followed by Fast Track designation in March 2025.
- Clinical Efficacy: Results from the Phase 2 DAHLIAS trial showed significant improvement in systemic disease activity and patient-reported symptoms. A Phase 3 study is ongoing.
Ianalumab: A Dual-Action B-Cell Therapy
Ianalumab (VAY736) from Novartis is another promising investigational fully human monoclonal antibody. It targets B-cells, which are involved in Sjögren's, through a dual mechanism that combines B-cell depletion and inhibition of BAFF-R signaling.
- Positive Phase 3 Results: In August 2025, Novartis announced positive top-line results from its two Phase 3 trials, NEPTUNUS-1 and NEPTUNUS-2. Both trials met their primary endpoint by demonstrating statistically significant improvements in disease activity. This is noted as the first time a global Phase 3 trial in Sjögren's has achieved such a significant reduction in disease activity.
- Next Steps: Novartis plans to submit the data from these successful trials to regulatory authorities globally.
Experimental Cell Therapy for Dry Mouth
Beyond systemic treatments, research is also exploring ways to address specific symptoms. In February 2025, a clinical trial began at the University of Wisconsin for an experimental cell therapy targeting severe dry mouth (xerostomia) by aiming to repair damaged salivary glands.
A Comparison of Leading Investigational Therapies
To provide a clearer picture of the primary new drug candidates, here is a comparison of nipocalimab and ianalumab.
Feature | Nipocalimab | Ianalumab (VAY736) |
---|---|---|
Manufacturer | Johnson & Johnson | Novartis |
Mechanism of Action | Blocks FcRn to reduce circulating IgG autoantibodies. | Dual action: B-cell depletion (via ADCC) and BAFF-R inhibition. |
Clinical Trial Stage | Phase 3 underway. | Phase 3 completed with positive results (Aug 2025). |
FDA Designations | Breakthrough Therapy (Nov 2024), Fast Track (Mar 2025). | Fast Track (granted prior to Aug 2025). |
Targeted Problem | Reduction of systemic disease activity driven by IgG autoantibodies. | Reduction of disease activity driven by B-cells. |
Administration | Intravenous infusion. | Not specified, but Phase 3 tested monthly and quarterly dosing. |
The Impact of New Research and Patient Advocacy
The progress in developing new therapies is partly due to improved clinical trial design, which now often includes stricter criteria focusing on patients with higher disease activity and autoantibody positivity to better evaluate treatment effects. The Sjögren's Foundation also plays a key role in supporting research and raising awareness for the patient community.
Conclusion: Hope for the Future
The emergence of targeted therapies like nipocalimab and ianalumab represents a significant advancement in the potential treatment of Sjögren's disease. These investigational drugs offer the possibility of addressing the underlying causes of the disease rather than just managing symptoms, providing a hopeful outlook for patients. While regulatory approval is still needed, the positive clinical trial results and expedited designations underscore the potential for a new era of Sjögren's treatment.
