Operating as a clinical-stage biotechnology firm, Q32 Bio Inc. is dedicated to developing biologic therapies aimed at re-establishing healthy immune equilibrium in patients across the United States suffering from autoimmune and inflammatory disorders stemming from dysfunctional immune responses. The company's primary investigational therapy, ADX-097, is a humanized anti-C3d monoclonal antibody fusion protein designed to normalize complement regulation. This candidate has successfully finished its Phase I clinical trial, targeting severe renal and other complement-driven conditions where patient needs are largely unmet, such as lupus nephritis, IgA nephropathy, C3 glomerulopathy, and ANCA-associated vasculitis. Additionally, Q32 Bio is advancing Bempikibart (ADX-914), a fully human monoclonal antibody antagonist against interleukin-7 receptor alpha. Currently in Phase II trials, Bempikibart aims to recalibrate adaptive immune responses by inhibiting signaling pathways involving interleukin-7 and thymic stromal lymphopoietin, offering potential treatment for atopic dermatitis and alopecia areata. Founded in 2017 and headquartered in Waltham, Massachusetts, Q32 Bio Inc. adopted its current name in April 2020, having previously operated as AdMIRx Inc.
Q32 Bio Presents Results from Part B of the SIGNAL-AA Clinical Trial of Bempikibart in Alopecia Areata in a Late-Breaker at the European Academy of Dermatology and Venereology Congress 2026
Q32 Bio presented 36-week Part B results from the SIGNAL-AA Phase 2a trial of bempikibart in severe alopecia areata at the EADV 2026 congress as a late-breaker, showing a mean SALT score reduction of 35.3% and SALT-20 responses in 40% of mITT patients.
Durability was a highlight: in the 16-week off-drug period, 44% of patients maintained SALT-20 and 100% of Week-36 responders maintained response, supporting potential less frequent chronic maintenance dosing.
Safety was clean with no serious or Grade 3+ treatment-related adverse events, and the company plans to advance bempikibart into a registration-directed program in the first half of 2027, subject to regulatory discussions planned for H2 2026.
