This study will assess the safety and preliminary efficacy of the bi-specific TCE, alnuctamab (known as BMS-986349, CC-93269, EM901), targeting BCMA in patients with moderate to severe SLE, refractory to standard-of-care treatments.Read full original descriptionShow less
Open-label, 4-Part Study to Investigate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of Alnuctamab (BMS-986349/CC-93269) in Participants With Moderate to Severe Refractory Systemic Lupus Erythematosus
This study will assess the safety and preliminary efficacy of the bi-specific TCE, alnuctamab (known as BMS-986349, CC-93269, EM901), targeting BCMA in patients with moderate to severe SLE, refractory to standard-of-care treatments.
Inclusion: Age 18-60 years; Documented diagnosis of SLE fulfilling 2019 ACR/EULAR criteria; Historical documentation of ANA (1:80 or greater) autoantibody on immunofluorescence as well as presence of at least 1 additional autoantibody of the type: anti-dsDNA, anti-histone, anti-chromatin, anti-Smith, anti-RNP, anti-Ro/SSA, anti-La/SSB, anti-cardiolipin (IgG), or anti-beta2-glycoprotein1 (IgG); History of SLE that is refractory to corticosteroids and at least 2 immunosuppressive therapies with different mechanisms of action (methotrexate, thiopurines, mycophenolate mofetil, calcineurin inhibitors, biologic agents, cyclophosphamide), including at least one biologic therapy (e.g. anti-CD20 therapy, anifrolumab, belimumab) or cyclophosphamide. Of note, hydroxychloroquine is not considered an immunosuppressive therapy, and methotrexate/azathioprine counts as a single drug class); Total SLEDAI-2K >6 with clinical SLEDAI-2K >4, or >1 BILAG A organ domain score, or >2 BILAG B, but without active central nervous system (CNS) disease within the past year; a maximum of two participants with only arthritis and/or rash can be included if truly disabling.
Exclusion: Autoimmune disease other than SLE, except associated Sjogren's Disease if not primary contributor to symptoms; coexistent fibromyalgia will be allowed if not primary contributor to symptoms; Active or suspected infection, including HIV; TTP-like SLE; catastrophic APS; LN WHO class V as primary qualifying criterion (unless overlap with Class III or IV), rapidly progressive LN, or eGFR <40 mL/min; active CNS pathology attributable to neuropsychiatric SLE; O2 sat <92% on room air; ANC <1500u/L, Hgb <8g/dL, Plt <75,000/uL; ALT or AST > 2X ULN (unless attributed to active myositis), Total Bilirubin >1.5 X ULN (unless Gilbert's Disease), total B cell count <12/microliter, hypogammaglobinemia <500mg/dL.
