Novartis announces both ianalumab Phase III clinical trials met primary endpoint in patients with Sjögren's disease

Ad hoc announcement pursuant to Art. 53 LR NEPTUNUS-1 and NEPTUNUS-2 are the first ever global phase III trials to demonstrate statistically significant reduction in disease activity for Sjögren’s disease1 Ianalumab has the potential to become the first and only targeted treatment approved for patients with Sjögren’s diseaseIanalumab was well tolerated and demonstrated a favorable safety profile in Sjögren's disease1,2Novartis plans to present its data at an upcoming medical congress and submit to health authorities globally Basel, August 11, 2025 – Novartis today announced positive top-line results from its Phase III trials evaluating ianalumab (VAY736) in adults with active Sjögren's disease. Both trials met the primary endpoint of demonstrating statistically significant improvements in disease activity1. These results support the potential for ianalumab, a drug with a dual mechanism of action, B-cell depletion and BAFF-R inhibition, to become the first targeted treatment for patients with Sjögren’s disease, a chronic, disabling autoimmune disease3,4,5. "Sjögren’s disease is a serious, progressive, systemic autoimmune disease, often unrecognized or misdiagnosed with a significant detrimental impact to quality of life, with very limited treatment options and an established unmet need. Both Phase III trials demonstrate that ianalumab improves disease activity in patients with Sjogren’s disease.” said Shreeram Aradhye, M.D., President of Development and Chief Medical Officer at Novartis. “These Phase III studies mark a significant milestone. We look forward to engaging with health authorities to discuss these findings in the near future.” The NEPTUNUS pivotal trials achieved the primary endpoint of improving disease activity measured by a reduction in EULAR Sjögren’s syndrome disease activity index (ESSDAI), a multi-dimensional disease activity measurement compared to placebo1. Ianalumab was well tolerated and demonstrated a favorable safety profile in Sjögren's disease1,2. Novartis plans to present the NEPTUNUS-1 and NEPTUNUS-2 data at an upcoming medical meeting and submit ianalumab, which was granted Fast Track Designation by the US Food and Drug Administration (FDA), to health authorities globally6. About ianalumab Ianalumab (VAY736) is a novel fully human monoclonal antibody being investigated for its potential to treat various B cell-driven autoimmune diseases, including Sjögren’s disease, immune thrombocytopenia (ITP), systemic lupus erythematosus (SLE), lupus nephritis (LN), warm autoimmune hemolytic anemia (wAIHA) and diffuse cutaneous systemic sclerosis (dcSSc)3,7-13. Its mechanism of action targets B cells in two ways, namely combining B cell depletion via antibody-dependent cellular toxicity (ADCC) and interruption of BAFF- R mediated signals of B cell function and survival3. In clinical trials, ianalumab showed promising efficacy and a favorable safety profile in Sjögren’s disease, systemic lupus erythematosus, and immune thrombocytopenia2,14,15. Ianalumab originates from an early collaboration with MorphoSys AG, a company which Novartis later acquired in 202416. About NEPTUNUS-1 and NEPTUNUS-2 The phase III clinical trials, NEPTUNUS-1 and NEPTUNUS-2, are global, multicenter, pivotal studies evaluating the efficacy and safety of ianalumab in patients with Sjögren’s disease7,8. These trials were designed to provide comprehensive data on ianalumab's potential as a targeted treatment for Sjögren’s disease, in patients with active extraglandular disease.3,7,8. NEPTUNUS-1 is a randomized, double-blind, 2-arm multicenter phase III trial (N=275) to evaluate the clinical efficacy, safety, and tolerability of ianalumab 300 mg subcutaneous (s.c.) monthly compared with placebo for 52 weeks7. NEPTUNUS-2 is a randomized, double-blind, 3-arm multicenter phase III trial (N=504) to evaluate the clinical efficacy, safety, and tolerability of ianalumab 300 mg s.c. monthly or every 3 months compared with placebo for up to 52 weeks8. The primary endpoint was measured by improvements in systemic disease activity using ESSDAI (EULAR Sjögren’s syndrome disease activity index)7,8. Patients currently enrolled in NEPTUNUS-1 and NEPTUNUS-2 have been given the opportunity to continue follow-up in these studies or enter a long-term extension trial17. About Sjögren’s disease (previously called Sjögren’s syndrome) Sjögren’s disease is a systemic, chronic autoimmune disorder that causes inflammation and tissue damage, impacting the entire body4. It primarily affects exocrine glands, leading to excessive dryness, with over 90 percent of patients experiencing dry eyes and dry mouth4,18. The disease is heterogenous, patients experience dryness, fatigue and widespread pain and 30-40 percent of patients will also show extraglandular organ involvement5,19. Extraglandular manifestation can be very diverse and can affect skin, musculoskeletal system, kidneys, lungs and other organs19. The risk of lymphoma is increased in patients with Sjögren’s5. Sjögren’s is one of the most prevalent rheumatic autoimmune diseases, affecting approximately 0.25 percent of the population with an estimated 50 percent undiagnosed 20-21. Sjögren’s is nine times more common in women than men4. B cell dysfunction plays a significant role in the disease by causing an autoimmune response that leads to inflammation and tissue damage3,4. There are no systemic treatments approved, with only limited symptomatic treatments available to provide temporary and partial symptomatic relief, highlighting the need for effective targeted therapies3.
