Q32 Bio Announces Completion of Enrollment in the SIGNAL-AD Phase 2 Clinical Trial of Bempikibart for Atopic Dermatitis
-- Exceeded enrollment target due to patient demand; trial size increased to 121 patients --
-- Bempikibart topline results remain on track to be released in Q4'24 --
"We are grateful to the patients and their clinical teams whose high level of interest enabled us to complete enrollment on schedule while exceeding our original target enrollment," said
"In addition to completing enrollment in SIGNAL-AD, we previously announced that enrollment in the SIGNAL-AA Phase 2 clinical trial in severe alopecia areata (AA) is also complete, marking the achievement of two critical milestones this year," said
SIGNAL-AD (NCT05509023) is a two-part Phase 2, randomized, double-blind, placebo-controlled, multi-center clinical trial evaluating bempikibart in adult patients with persistent, moderate-to-severe AD. Part A was conducted to evaluate safety, PK, and to enable dose selection for Part B of the clinical trial. Part A was completed, but data remains blinded. Part B is being conducted to evaluate the efficacy and safety of bempikibart as compared with placebo. In Part B, patients were enrolled 1:1 in the bempikibart 200 mg Q2W SC flat dose and placebo arms for 12 weeks of treatment. The primary endpoint is the mean percent change from baseline to week 14 in the Eczema Area and Severity Index (EASI) score. Patients will be followed for an additional 12 weeks following completion of treatment.
A total of 121 patients were enrolled, including 15 patients in Part A. Total enrollment exceeded the initial target of approximately 100 patients due to Part B patient enrollment demand. Topline data from Parts A and B are expected in the fourth quarter of 2024.
AD is the most common type of eczema and affects more than 25 million people in
About Bempikibart
Bempikibart (ADX-914) is a fully human anti-IL-7Rα antibody that is designed to re-regulate adaptive immune function by blocking IL-7 and TSLP signaling.

About Q32 Bio
Q32 Bio is a clinical stage biotechnology company developing biologic therapeutics targeting potent regulators of the innate and adaptive immune systems to re-balance immunity in autoimmune and inflammatory diseases. Q32 Bio's lead programs, focused on the IL-7 / TSLP receptor pathways and complement system, address immune dysregulation to help patients take back control of their lives.
Q32 Bio's program for adaptive immunity, bempikibart (ADX-914), is a fully human anti-IL-7Rα antibody that re-regulates adaptive immune function for the treatment of autoimmune diseases. It is being evaluated in two Phase 2 trials for the treatment of atopic dermatitis and alopecia areata. The IL-7 and TSLP pathways have been genetically and biologically implicated in driving several T cell-mediated pathological processes in numerous autoimmune diseases. Q32 Bio's program for innate immunity, ADX-097, is based on a novel platform enabling tissue-targeted regulation of the complement system without long-term systemic blockade – a key differentiator versus current complement therapeutics. Q32 Bio has completed a first-in-human, Phase 1 ascending dose clinical study of ADX-097 in healthy volunteers.
