(Oral #001)\nResults from the ongoing open-label extension (OLE) study evaluating long-term efficacy and safety of nipocalimab show sustained disease control with nipocalimab in a broad population of antibody-positive gMG adult patients. (Poster #11-022)\n\nReal-world evidence and unmet needs in myasthenia gravis (MG) treatment\n\nReal-world data showcases the unmet needs in treating gMG during pregnancy, and an urgency for further research on treatment options for women with MG who might become pregnant. (Oral #005) Nipocalimab continues to be the only investigational treatment with both published data and ongoing Phase 3 studies in pregnant women at risk of alloantibody conditions of pregnancy, including hemolytic disease of the fetus and newborn (HDFN), and fetal neonatal alloimmune thrombocytopenia (FNAIT).1,2,3\nPoster presentations highlight data from two studies examining the association of oral corticosteroid (OCS) exposure in MG, emphasizing the need for additional targeted treatment options with demonstrated safety profiles to minimize the well-known risks of oral corticosteroids. (Posters #11-029 and #8-007)\nFindings from a real-world study of MG serostatus testing show variation in MG antibody testing in current clinical practice, uncovering infrequent MuSK and LRP4 testing among antibody negative patients. The study found a socioeconomic correlation to lack of further diagnostic testing which highlights an opportunity in care and can inform more targeted treatment plans. (Poster #11-030)\n\nPatient-reported data & disease burden:\n\nA poster presentation will showcase patient-reported insights on factors contributing to MG exacerbations and symptom worsening (Poster #11-010):\n   \nFindings suggest that many individuals currently living with MG in the U.S. reported uncontrolled disease. Important risk factors identified for exacerbation or symptom worsening included living alone, generalized MG symptomology, and comorbid anxiety/depression.\n\n\nThese findings underscore the ongoing need for additional approved immunoselective therapies that are effective with demonstrated safety profiles for people living with gMG.\n\"We're excited to share our latest research in gMG, reinforcing our commitment to advancing innovation in the autoantibody disease space. These presentations highlight our dedication to helping address critical unmet needs and improving outcomes for a broad population of patients through our pathway-based approach to research and development,\" said Katie Abouzahr, M.D., Vice President, Autoantibody and Maternal Fetal Immunology Disease Area Leader, Johnson & Johnson Innovative Medicine. \"We look forward to engaging with the medical and patient community at AAN and continuing important scientific exchange that drive progress in patient care.\"\nThe full list of accepted Johnson & Johnson abstracts is below.\nData presentation highlights: AAN – April 5-9\n\n\n\n\nPresenter/Presentation Time (PT)  Poster Number \nAbstract Name  \n\n\nOral Session \n\n\n\nSession 34 #001 Date: Wednesday, April 9 Presentation Time: 1:00 PM  \nPh3 VIVACITY QMG: Efficacy of Nipocalimab, a Novel Neonatal Fragment Crystallizable Receptor Blocker, as Measured Using Quantitative Myasthenia Gravis Assessment: Findings from the Phase 3 Placebo-controlled Vivacity-MG3 Study \n\n\nSession 34 #005 Date: Wednesday, April 9  Presentation Time: 1:48 PM  \nKomodo: Real-world Interaction between Pregnancy and Generalized Myasthenia Gravis \n\n\nPoster Session \n\n\n\nSession 7 #11-022 Date: Monday, April 7  Session Time: 5:00 PM – 6:00 PM \nPh3 VIVACITY OLE: Long-Term Safety and Efficacy of Nipocalimab in Generalized Myasthenia Gravis: Vivacity-MG3 Open-Label Extension Phase Results \n\n\nSession 6 #11-027 Date: Monday, April 7 Session Time: 11:45 AM –12:45 PM  \nKomodo: Real-world Treatment Patterns Among Patients with Generalized Myasthenia Gravis \n\n\nSession 9 #11-034 Date: Tuesday, April 8 Presentation Time: 11:45 AM – 12:45 PM  \nHCRU: Economic Burden of Myasthenia Gravis Exacerbation and Crisis from US Payer Perspective \n\n\nSession 7 #11-029 Date: Monday, April 7 Presentation Time: 5:00 PM – 6:00 PM \nOCS SWIMM: Long-term Use of Oral Corticosteroids and Overall Survival Among Patients with Myasthenia Gravis: A Nationwide Population-based Study \n\n\nSession 1 #11-010 Date: Saturday, April 5  Presentation Time: 11:45 AM – 12:45 PM \nMGFA Patient Registry: Identifying Risk Factors for Exacerbation and Symptom Worsening—a Retrospective Cohort Study of Patients with Myasthenia Gravis in the United States \n\n\nSession 8 #11-032 Date: Tuesday, April 8   Presentation Time: 8:00 AM – 9:00 AM \nMeasures that Matter: Design of a Digital Solution to Improve Myasthenia Gravis Patient Symptom Tracking in Routine Clinical Care \n\n\nSession 6 #11-030 Date: Monday, April 7   Presentation Time: 11:45 AM – 12:45 PM \nHealth Analytics: Serostatus Testing Patterns Among Individuals with Myasthenia Gravis: Implications for Patient Care \n\n\nSession 1 #11-022 Date: Saturday, April 5 Presentation Time: 11:45 AM – 12:45 PM \nADELPHI DSP 2: Treatment-related Characteristics Among Younger Women with Generalized Myasthenia Gravis \n\n\nSession 4 #8-007 Date: Sunday, April 6 Presentation Time: 5:00 PM – 6:00 PM \nOptum: Complications in Patients with Myasthenia Gravis Treated with Oral Corticosteroids \n\n\nSession 4 #8-001 Date: Sunday, April 6 Presentation Time: 5:00 PM – 6:00 PM \nOptum: Healthcare Costs in a Commercially Insured Population of Patients with Generalized Myasthenia Gravis and Related Clinical Events \n\n\n\n\nEditor's notes:\n\n\n\n\na. \nQMG (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 indicated greater disease severity. \n\n\nb. \nMG-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.  \n\n\n\n\nABOUT GENERALIZED MYASTHENIA GRAVIS (gMG)\nMyasthenia 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] or anti-low density lipoprotein-related protein 4 [LRP4]), which target proteins at the neuromuscular junction and can block or disrupt normal signaling from nerves to muscles, thus impairing or preventing muscle contraction.4,5,6 The disease impacts an estimated 700,000 people worldwide.4 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.7 Roughly 50 percent of individuals diagnosed with MG are women, and about one in five of those women are of child-bearing potential.8,9,10Approximately 10 to 15% of new cases of MG are diagnosed in adolescents (12 – 17 years of age).11,12,13 Among juvenile MG patients, girls are affected more often than boys with over 65% of pediatric MG cases in the U.S. diagnosed in girls.14,15,16\nInitial disease manifestations are usually ocular but approximately 85 percent of MG patients experience additional advancements to the disease manifestations—referred to as generalized myasthenia gravis (gMG). This is characterized by severe muscle weakness and difficulties in speech and swallowing.17,18,19,20,21 Approximately 100,000 individuals in the U.S. are living with gMG.22 Vulnerable gMG populations, such as pediatric patients, have more limited therapeutic options.23 Currently, SOC treatments for adolescents with gMG are extrapolated from adult trials.13 Other than symptomatic treatments, there are no approved FcRn blockers for adolescents with gMG in the United States.13 \nABOUT THE PHASE 3 VIVACITY-MG3 STUDY\nThe Phase 3 Vivacity-MG3 study (NCT04951622) was specifically designed to measure sustained efficacy and safety with consistent dosing in this unpredictable chronic condition where unmet need remains high. 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.24,25 Randomization 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.24 Baseline demographics were balanced across arms (77 nipocalimab, 76 placebo).24 The primary endpoint of the study was mean change in MG-ADLb score from baseline over Weeks 22, 23 and 24 in antibody positive patients. A key secondary endpoint included change in QMG score. Long-term safety and efficacy were further assessed in an ongoing open-label extension (OLE) phase.25 \nABOUT NIPOCALIMAB\nNipocalimab is an investigational monoclonal antibody, designed to bind with high affinity to block FcRn and reduce levels of circulating immunoglobulin G (IgG) antibodies potentially without impact on other immune functions. This includes autoantibodies and alloantibodies that underlie multiple conditions across three key segments in the autoantibody space including Rare Autoantibody diseases, Maternal Fetal diseases mediated by maternal alloantibodies and Rheumatic diseases.3,25,26,27,28,29,30,31,32 Blockade of IgG binding to FcRn in the placenta is also believed to limit transplacental transfer of maternal alloantibodies to the fetus.33,34\nThe U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) have granted several key designations to nipocalimab including: \n\nU.S. FDA Fast Track designation in HDFN and warm autoimmune hemolytic anemia (wAIHA) in July 2019, gMG in December 2021, FNAIT in March 2024 and Sjögren's disease (SjD) in March 2025\nU.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\nU.S. FDA Breakthrough Therapy designation for HDFN in February 2024 and for Sjögren's disease in November 2024\nU.S. FDA granted Priority Review in gMG in Q4 2024\nEU EMA Orphan medicinal product designation for HDFN in October 2019\n\nABOUT JOHNSON & JOHNSON \nAt Johnson & Johnson, we believe health is everything.
