Through 120 weeks of follow-up, nipocalimab delivered sustained clinical improvements and reductions in total IgG in antibody-positive adult patients including anti-AChR+ and anti-MuSK+ Patients achieving sustained minimal symptom expression (MSE) experienced greater improvements in quality of life than those with transient MSE in a post-hoc analysis of the Phase 3 study EPIC, a head-to-head study, will compare nipocalimab versus another FcRn blocker in generalised myasthenia gravis a BEERSE, BELGIUM, April 23, 2026 (GLOBE NEWSWIRE) -- Johnson & Johnson today announced new data from the Phase 3 Vivacity-MG3 study and ongoing open label extension (OLE) in a broad population of antibody-positive (including anti-AChR+ b and anti-MuSK+ c ) adults with generalised myasthenia gravis (gMG) reinforcing the efficacy, sustained disease control, and safety pro IMAAVY ® ▼(nipocalimab). 1 These data are among the seven abstracts Johnson & Johnson is presenting at the American Academy of Neurology (AAN) 2026 Meeting in Chicago, Illinois. “For people living with gMG, consistent and durable symptom control is the central goal of treatment,” said Constantine Farmakidis M.D., Associate Professor of Neurology at the University of Kansas Medical Center d . “These long-term results, now extending to beyond two years, provide further evidence that disease control, as initially observed in the nipocalimab phase 3 pivotal study, can be sustained, and add to the body of evidence that may help guide clinical decision-making.” Sustained disease control is a key treatment objective in gMG, as long-term maintenance of low disease activity can help prevent exacerbations, reduce treatment burden and support meaningful function outcomes. 1 , 2 , 3 , 4 , 5 , 6 In addition, new post-hoc analyses explore the clinical relevance of sustained minimal symptom expression (MSE), an emerging patient-centric treatment goal that reflects minimal day-to-day disease impact for people living with gMG. 2 , 3 Long-Term Data from OLE Phase After the 24-week double-blind phase of the study, patients entered the ongoing OLE phase, with the latest results reflecting a maximum of 120 weeks of observation – among the longest follow-up periods reported for any FcRn blocker study in gMG. 1 At 96 weeks in the OLE, nipocalimab demonstrated: Sustained improvements in MG-ADL e and QMG f scores over time, with mean reductions of 6.47 g points on the total MG-ADL (standard error [SE]=1.20, p<0.001) and 5.97 g points (SE=1.28, p<0.001) on the total QMG scales – measures of MG symptom impact on daily living and muscle strength. 1 , 7 , 8 Half of patients achieved MSE (n=153) and nearly one-third (32%) achieved sustained MSE for at least 8 weeks on nipocalimab treatment. 1 Incremental reduction of corticosteroid use was also observed through the OLE, with 57% of patients reaching low doses of ≤10 or ≤5 mg/day. 1 Greater than 64% g reduction in total immunoglobulin G (IgG), including pathogenic IgG autoantibodies, the underlying driver of disease (n=31, standard deviation [SD]=12.91). 1 There were no unexpected adverse events (AEs) during the OLE. The most common AEs associated with nipocalimab include muscle spasms, peripheral oedema, increased lipids and decreased serum albumin. 1 , 9 , h “These long-term findings for nipocalimab reflect continued momentum in transforming the treatment landscape for people living with generalised myasthenia gravis,” said Mark Graham, Therapeutic Area Head, Immunology, Europe, Middle East and Africa Johnson & Johnson. “Evidence demonstrating sustained disease control alongside sustained improvements in quality of life underscores our progress toward more effective treatment options. We remain committed to advancing innovative approaches that address persistent unmet needs and improve long-term outcomes for patients.” Minimal Symptom Expression Data from Double-Blind Phase A new post-hoc analysis from the 24-week double-blind portion of the study evaluated the impact of sustained MSE on quality of life (based on MG‑QoL‑15r i measure): 2 Adults who received nipocalimab plus standard of care (SOC) j were four times more likely to reach sustained MSE, defined as achieving an MG-ADL score of 0 or 1 and maintaining it for at least 8 weeks ([95% CI]: 4.35 [1.37, 13.81], p=0.013), compared to those randomised to placebo. 2 Patients who reached this level at Week 24 and sustainment of symptom control experienced greater improvements in day‑to‑day quality of life ([95% CI]: −12.7, n=19, p<0.001), compared with those with improvements that were not similarly sustained (−8.7, n=14, p=0.016), or among those who did not attain MSE (−4.1, n=96, p<0.001). 2 Editor’s Notes: Study details, including participating locations and eligibility criteria, are available on ClinicalTrials.gov. 10 AChR+= anti-acetylcholine receptor positive antibody MuSK+= anti-muscle specific tyrosine kinase positive antibody Dr. Constantine Farmakidis M.D. has provided consulting, advisory, and speaking services to Johnson & Johnson. He has not been paid for any media work. MG-ADL (Myasthenia Gravis – Activities of Daily Living) provides a rapid clinical assessment of the patient's recall of symptoms impacting activities of daily living, with a total score range of 0 to 24; a higher score indicates greater symptom severity. 7 QMG (Quantitative Myasthenia Gravis) is a 13-item assessment by a clinician that quantifies MG disease severity. The total QMG score ranges from 0 to 39, where higher scores indicate greater disease severity. 8 Results reflect patients receiving nipocalimab and SOC throughout both the 24-week double-blind phase and OLE phase of the study. 1 The overall incidence of AEs, serious adverse events (SAEs) and AEs leading to discontinuation were similar to that in the placebo plus SOC group. 1 Specifically, 46% of patients (n=64) treated with nipocalimab plus SOC experienced AEs, matched by 45% (n=62) in the placebo plus SOC group. 1 SAEs were reported by 3% of patients (n=5) in the nipocalimab plus SOC group compared to 8% (n=11) in the placebo plus SOC group. 1 As measured by MG-QoL-15r (Myasthenia Gravis Quality of Life 15-item Scale – Revised), a scale designed to assess important aspects of the patient's experience related to MG. 2 Standard of care was defined as a stable dose of current gMG treatment, including acetylcholinesterase inhibitors, glucocorticosteroids or immunosuppressants (e.g, azathioprine, mycophenolate mofetil or mycophenolic acid, methotrexate, ciclosporin, tacrolimus, or cyclophosphamide). 11 ABOUT GENERALISED MYASTHENIA GRAVIS (gMG) Myasthenia gravis (MG) is an autoantibody disease in which the immune system mistakenly makes antibodies (e.g., anti-acetylcholine receptor [AChR], anti-muscle-specific tyrosine kinase [MuSK]), which target proteins at the neuromuscular junction and can block or disrupt normal signaling from nerves to muscles, thus impairing or preventing muscle contraction. 12 , 13 The disease impacts between 56,000 and 123,000 people in Europe and an estimated 700,000 people worldwide. 14 , 15 The disease affects both men and women and occurs across all ages, racial and ethnic groups, but most frequently starts in young women and older men. 14 Roughly 50 percent of individuals diagnosed with MG are women, and about one in five of those women are of child-bearing potential. 16 , 17 , 18 Approximately 10 to 15% of new cases of MG are diagnosed in paediatric patients 12-17 years of age. 17 , 19 , 20 , 21 Among juvenile MG patients, girls are affected more often than boys with over 65% of paediatric MG cases in the EU diagnosed in girls. 22 , 23 , 24 Initial disease manifestations are usually eye-related but approximately 85% of MG patients experience additional advancements to the disease manifestations – referred to as generalised myasthenia gravis (gMG). 25 , 26 , 27 , 28 , 29 , 30 This is characterised by severe muscle weakness and difficulties in speech and swallowing. 26 , 28 , 29 , 30 , 31 , 32 Vulnerable gMG populations, such as paediatric patients, have more limited therapeutic options. 32 ABOUT THE PHASE 3 VIVACITY-MG3 STUDY The Phase 3 Vivacity-MG3 study ( NCT04951622 /2023-504152-97) was specifically designed to measure sustained efficacy and safety with consistent dosing in this unpredictable chronic condition where unmet need remains high. 14 , 33 , 34 Antibody positive or negative adult gMG patients with insufficient response (MG-ADL ≥6) to ongoing SOC therapy were identified and 199 patients, 153 of whom were antibody positive, enrolled in the 24-week double-blind placebo-controlled trial. 33 , 34 Randomisation was 1:1, nipocalimab plus current SOC (30 mg/kg IV loading dose followed by 15 mg/kg every two weeks) or placebo plus current SOC. 34 Baseline demographics were balanced across arms (77 nipocalimab, 76 placebo) . 34 The primary efficacy endpoint was the comparison of the mean change from baseline to Weeks 22, 23, and 24 between treatment groups in the MG-ADL total score. 33 A key secondary endpoint included change in Quantitative Myasthenia Gravis (QMG) score. 33 Long-term safety and efficacy were further assessed in an ongoing open-label extension (OLE) phase. 1 ABOUT IMAAVY ® (nipocalimab) Nipocalimab is an immunoselective treatment designed to target, bind with high affinity, and block FcRn, reducing circulating IgG antibodies that drive disease while also preserving key immune functions. 35 , 36 , 37 Nipocalimab is currently approved in the European Union as an add-on to standard therapy for the treatment of gMG, in adults and adolescent patients aged 12 years of age and older who are AChR or MuSK antibody positive. 9 , 38 Nipocalimab is being investigated across three key segments in the autoantibody space including Rheumatologic diseases, Rare Autoantibody diseases, and Maternal Foetal diseases mediated by maternal alloantibodies, in which blockade of IgG binding to FcRn in the placenta is believed to limit transplacental transfer of maternal alloantibodies to the fetus. 33 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 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 haemolytic disease of the foetus and newborn (HDFN) in October 2019 and foetal and neonatal alloimmune thrombocytopenia (FNAIT) in April 2025 U.S. FDA Fast Track designation in HDFN and warm autoimmune haemolytic anaemia (wAIHA) in July 2019, 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
