Mycophenolate Mofetil

– All 12 patients in study (100%) achieved insulin independence, producing their own insulin and no longer requiring exogenous insulin therapy to manage their T1D – All 12 patients also achieved an HbA1c below 6.5%, with a mean most recent HbA1c of approximately 5.4%, representing an approximately 2.6% average improvement in HbA1c from baseline – No severe hypoglycemic episodes were reported post-transplant, compared with a history of recurrent severe hypoglycemic events prior to transplantation in all enrolled patients IRVINE, Calif., June 08, 2026 (GLOBE NEWSWIRE) -- Eledon Pharmaceuticals, Inc. (“Eledon”) (NASDAQ: ELDN) today announced updated results from an investigator-initiated trial evaluating tegoprubart, its investigational anti-CD40L antibody, as part of a calcineurin inhibitor-free immunosuppression regimen in patients with type 1 diabetes undergoing allogeneic islet cell transplantation at the University of Chicago Medicine Transplant Institute. The results were presented by trial investigator Piotr Witkowski, M.D., Ph.D., Director of the Pancreas and Islet Transplant Program at UChicago Medicine, at the American Diabetes Association 86th Scientific Sessions, taking place June 5-9, 2026, in New Orleans, Louisiana. All patients treated in the study (n=12) showed rapid improvement in glycemic control following islet transplantation and treatment with tegoprubart, with stable islet graft function observed across the cohort over a median and maximum post-transplant follow-up period of 8 and 22 months, respectively. All 12 patients achieved insulin independence, meaning that they no longer needed chronic, exogenous insulin therapy to manage their T1D. Also, all patients demonstrated a most recent hemoglobin A1C (“HbA1c”) below the diabetic threshold of 6.5%, with a mean most recent HbA1c of approximately 5.4% across the cohort. While all patients enrolled reported recurrent severe hypoglycemic events pre-transplant, no severe hypoglycemic episodes were reported following transplantation. Severe hypoglycemia is a serious complication of type 1 diabetes that may require emergency medical intervention and can cause loss of consciousness, seizures, injury, or death. Recurrent severe hypoglycemic episodes can significantly impact patients’ daily activities and quality of life. Higher levels of post-transplant islet cell engraftment were observed with the tegoprubart-based immunosuppression regimen than in historical patients treated with a tacrolimus-based immunosuppression regimen at UChicago Medicine. There were no rejection episodes, and no patients developed de novo donor-specific HLA antibodies. Tegoprubart-based immunosuppression was generally well tolerated, with immunosuppression-related adverse events generally successfully treated by lowering the mycophenolic acid dose, if necessary. Additionally, no evidence of nephrotoxicity, hypertension or neurotoxicity, which are commonly associated with tacrolimus-based immunosuppression regimens, was observed. These findings further support the potential of CD40L blockade to enable effective islet graft protection while avoiding the toxicities of calcineurin inhibitors such as tacrolimus. The investigator-initiated pilot study enrolled 12 adults with long-standing T1D undergoing allogeneic islet transplantation at UChicago Medicine with a median duration of diabetes of approximately 33 years and mean HbA1c of approximately 8.0% prior to transplantation. Participants received tegoprubart, as part of a calcineurin inhibitor-free immunosuppression regimen. Calcineurin inhibitors such as tacrolimus are commonly used to prevent transplant rejection but can be associated with kidney toxicity, hypertension, neurological side effects, and harm to insulin-producing islet cells, limiting their suitability for long-term use in patients with T1D receiving an islet cell transplant. “T1D patients have been waiting decades for a potential functional cure, and it is exciting to see the progress being made in that direction through the emerging promise of tegoprubart,” said David-Alexandre C. Gros, M.D., Chief Executive Officer of Eledon. “For people who have difficulty managing T1D, a regimen that may protect an islet cell graft without the long-term burden associated with calcineurin inhibitors, the current standard of care, could be transformational. We are proud to support this important research effort led by Dr. Witkowski and the team at UChicago Medicine. We also look forward to working closely with the FDA towards our goal of receiving regulatory guidance on a path to market for tegoprubart in islet cell transplantation later this year.” “Insulin independence without the burden of traditional immunosuppression has long been one of cell replacement therapy's biggest goals,” said Aaron Kowalski, Ph.D., Chief Executive Officer of Breakthrough T1D. “Results like these show that this goal is becoming increasingly achievable. Breakthrough T1D is proud to fund this important study.” This UChicago Medicine-initiated clinical trial is funded by Breakthrough T1D, with initial support from The Cure Alliance. Breakthrough T1D has also committed to fund a second study evaluating tegoprubart as part of a calcineurin inhibitor-free immunosuppression drug regimen to prevent islet transplant rejection in individuals with T1D and chronic kidney disease. About Islet Transplantation for Type 1 Diabetes Pancreatic islet transplantation is a minimally invasive procedure developed to provide blood glucose control for subjects with type 1 diabetes and minimize or eliminate dependence on insulin. During the procedure, pancreatic islets containing insulin-producing beta cells are isolated from the pancreas of a deceased organ donor and infused through a small catheter into the patient’s liver. The islet cells lodge in small blood vessels in the liver and release insulin. After the procedure, subjects remain on immunosuppression therapy to prevent transplant rejection.

Nipocalimab – the first and only neonatal Fc receptor (FcRn) blocker to be studied in systemic lupus erythematosus – is designed to target and reduce pathogenic immunoglobulin G (IgG) autoantibodies associated with this disease while preserving immune function Results demonstrated significant reduction of systemic lupus erythematosus disease activity which continued beyond the 24-week primary endpoint, and were sustained through Week 52 in the nipocalimab 15 mg/kg groupa The ongoing Phase 3 study of nipocalimab is currently recruiting people living with systemic lupus erythematosus – a debilitating autoantibody-driven disease which can lead to systemic organ damage LONDON, June 3, 2026 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) today announced nipocalimab met the primary endpoint of decreasing disease activity at 24 weeks as measured by SLE Responder Index 4 (SRI-4)b and continued to demonstrate sustained reduction in disease activity in adults with moderate-to-severe systemic lupus erythematosus (SLE)a through 52 weeks in the Phase 2 JASMINE study as measured by both SRI-4b and Lupus Low Disease Activity State (LLDAS).c In addition, the study results showed greater response versus placebo plus background medicationd in participants who tested positive for lupus-associated autoantibodies, which represents the vast majority (~80%) of people living with SLE.e,1 These findings will be featured in a late-breaking presentation at the European Alliance of Associations for Rheumatology (EULAR) 2026 Congress in London and are among the 38 abstracts the Company is presenting across its Rheumatology portfolio. Nipocalimab is designed to selectively block the neonatal Fc receptor (FcRn), reducing levels of circulating pathogenic immunoglobulin (IgG) autoantibodies and immune complexes associated with inflammation in SLE.2,3 By reducing circulating IgG, including autoantibodies, nipocalimab is designed to target the underlying cause of disease while preserving critical immune functions.4 JASMINE is the first clinical study to demonstrate efficacy of FcRn blockade in SLE and provides clinical, biomarker and pharmacodynamic evidence supporting the continued investigation of nipocalimab as a potential treatment option for this disease.5 A healthcare professional's perspective "The consistent improvements observed across established disease activity measures and reductions in pathogenic immunoglobulin G autoantibodies are encouraging and support the continued investigation of nipocalimab as a targeted treatment approach for people living with systemic lupus erythematosus," said Richard Furie, M.D., Chief of the Division of Rheumatology at Northwell.f "These 52-week findings support the potential of nipocalimab to provide disease control over time for a broad population of autoantibody-positive adult patients living with moderate-to-severe systemic lupus erythematosus, a disease in which many patients experience ongoing disease activity and risk of irreversible organ damage." JASMINE Phase 2 clinical findings The Phase 2 JASMINE study is the first proof-of-concept for a FcRn-blocker in SLE and demonstrates the potential of nipocalimab to reduce disease activity, with greater responses observed in autoantibody-positive patients.1,5 The study met its primary endpoint at Week 24, with a greater proportion of patients receiving nipocalimab 15 mg/kg plus background medication achieving an SRI-4b response compared with placebo plus background medication (53.5% vs 46.7%). In a predefined autoantibody-positive patient populatione, greater SRI-4 response rates were observed (58.2% vs. 36.1%) and greater achievement of LLDAS (38.9% vs. 18.0%) compared with placebo plus background medication at Week 52. At Week 52, a key secondary endpoint, 53.6% of patients receiving nipocalimab 15 mg/kg achieved an SRI-4b response, compared with 39.7% for placebo plus background medication. More patients receiving nipocalimab 15 mg/kg also achieved LLDASc, a key exploratory endpoint that enables a treat-to-targetg approach, compared with placebo plus background medication (37.5% vs. 20.5%) at Week 52. Nipocalimab had a safety profile consistent with previous studies of nipocalimab and no new safety signals were identified. The most common adverse reactions in patients with SLE treated with nipocalimab (≥10%) were nasopharyngitis, headache, urinary tract infection and nausea.5 "The JASMINE results provide important new insights into the potential of nipocalimab for adults with moderate-to-severe systemic lupus erythematosus as we continue advancing this program," said Leonard L. Dragone, M.D., Ph.D., Disease Area Leader, Autoantibody and Rheumatology, Johnson & Johnson. "We are especially encouraged by the responses observed in autoantibody-positive study participants. These findings support the potential of nipocalimab as a targeted, immunoselective treatment designed to address underlying drivers of systemic lupus erythematosus." Nipocalimab received Fast Track Designation in SLE by the U.S. Food and Drug Administration (FDA) earlier this year. The ongoing Phase 3 GARDENIA study is currently recruiting. Editor's Notes: a. Nipocalimab is not FDA-approved for SLE. b. The SRI-4 is a composite measure used to assess treatment response in patients with SLE during clinical studies. It comprises criteria from three different internationally validated indices, SELENA-SLE Disease Activity Index (SELENA-SLEDAI), Physician Global Assessment (PGA) and the British Isles Lupus Assessment Group (BILAG) 2004. c. LLDAS definition: (1) SLE Disease Activity Index (SLEDAI)-2K ≤4, with no activity in major organ systems (renal, central nervous system (CNS), cardiopulmonary, vasculitis, fever) and no hemolytic anemia or gastrointestinal activity; (2) no new lupus disease activity compared with the previous assessment; (3) a Safety of Estrogens in Lupus Erythematosus National Assessment (SELENA)-SLEDAI physician global assessment (scale 0-3) ≤1; (4) a current prednisolone (or equivalent) dose ≤7.5 mg daily; and (5) well-tolerated standard maintenance doses of immunosuppressive drugs and approved biological agents. d. Protocol-permitted background medications include oral corticosteroids, antimalarials and no more than two of the following immunomodulatory drugs: azathioprine, mycophenolate mofetil, mycophenolic acid, oral methotrexate. e. The autoantibody-positive population was defined as participants who met ≥1 of the following during screening: (1) positive anti-double-stranded DNA (anti-dsDNA), (2) positive anti-Smith, (3) positive antinuclear antibodies (ANA) and positive for anti-Ro, anti-RNP or had a history of anti-dsDNA. f. Dr. Richard Furie has provided consulting, advisory and speaking services to Johnson & Johnson. He has not been paid for any media work. g. Treat-to-target in SLE is a therapeutic strategy in which treatment is guided by regular assessment of disease activity and adjusted to achieve a predefined target – primarily remission, or low disease activity if remission is not attainable – to improve long-term outcomes and prevent organ damage.6 ABOUT JASMINE JASMINE (NCT04882878) is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, parallel-group, dose-ranging study to evaluate nipocalimab in 228 adult participants with active systemic lupus erythematosus (SLE). Adults aged 18-65 years with moderate-to-severe SLE, defined by established measures of disease activity, who were positive for antinuclear antibodies (ANA), anti-double-stranded DNA (anti-dsDNA), and/or anti-Smith antibodies, and had not responded to at least one standard-of-care treatment were enrolled. Participants were randomized 1:1:1 to receive intravenous nipocalimab at 5 or 15 mg/kg, or placebo every 2 weeks through Week 52, in addition to protocol-permitted background medications. The primary endpoint was the SLE Responder Index-4 (SRI-4) composite response at Week 24. Pharmacodynamic effects and safety, including adverse events, were assessed through Week 58.5 ABOUT SYSTEMIC LUPUS ERYTHEMATOSUS Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease that occurs when the body's immune system mistakenly attacks its own healthy tissues.7,8 This can lead to inflammation and damage in many parts of the body, including the skin, joints, heart, lungs, kidneys and brain.3 SLE affects nine times more women than men, often striking initially between the ages of 15-44.9 In addition to systemic organ damage, other complications of SLE can include end-stage renal failure, scarring cutaneous lesions, neurological damage and various forms of cardiovascular disease.3 People living with SLE often face reduced health-related quality of life, due to severe fatigue, mood disturbances, joint pain, swelling and rashes, including the hallmark butterfly-shaped facial rash, as well as complications of long-term glucocorticoid use.10 Severe fatigue is the most widely reported and debilitating symptom of SLE, affecting up to 80% of people with SLE.11 SLE is the most common form of lupus, affecting 3 to 5 million people worldwide, approximately 70% of lupus cases.12,13 It is estimated that 450,000 people in the United States are affected by SLE.14 ABOUT NIPOCALIMAB Nipocalimab is an investigational immunoselective treatment designed to target, bind with high affinity, and block neonatal Fc receptor (FcRn), reducing circulating immunoglobulin G (IgG) antibodies that drive disease while also preserving key immune functions.2,3 Nipocalimab is being investigated across three key segments in the autoantibody space including Rheumatologic disease, Rare Autoantibody diseases and Maternal Fetal diseases mediated by maternal alloantibodies in which blockade of IgG binding to FcRn in the placenta is also believed to limit transplacental transfer of maternal alloantibodies to the fetus. 5,15,16,17,18,19,20,21,22,23 The U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) have granted several key designations to nipocalimab including:  EU EMA Orphan medicinal product designation for hemolytic disease of the fetus and newborn (HDFN) in October 2019 and fetal and neonatal alloimmune thrombocytopenia (FNAIT) in April 2025 U.S. FDA Fast Track designation in HDFN and warm autoimmune hemolytic anemia (wAIHA) in July 2019, generalized myasthenia gravis (gMG) in December 2021, FNAIT in March 2024, Sjögren's disease (SjD) in March 2025 and systemic lupus erythematosus (SLE) in January 2026 U.S. FDA Orphan drug status for wAIHA in December 2019, HDFN in June 2020, gMG in February 2021, chronic inflammatory demyelinating polyneuropathy (CIDP) in October 2021 and FNAIT in December 2023 U.S. FDA Breakthrough Therapy designation for HDFN in February 2024 and for SjD in November 2024 U.S. FDA granted Priority Review in gMG in Q4 2024 and in wAIHA in Q2 2026 ABOUT JOHNSON & JOHNSON At Johnson & Johnson, we believe health is everything.
