Q32 Bio to Present Tissue-Targeted Complement Inhibitor ADX-097 Positive Phase 1 Clinical Trial Results at the American Society of Nephrology Kidney Week 2024

October 14, 2024

— Poster presentation to highlight data from completed first-in-human, Phase 1 ascending dose clinical trial of ADX-097 in healthy volunteers; results support Phase 2 dose selection and continued clinical advancement of ADX-097 —

WALTHAM, Mass., Oct. 14, 2024 /PRNewswire/ — Q32 Bio Inc. (Nasdaq: QTTB) (“Q32 Bio”), a clinical stage biotechnology company focused on developing biologic therapeutics to restore immune homeostasis, today announced that it will present clinical data supporting its program for innate immunity, ADX-097, at the American Society of Nephrology (ASN) Kidney Week 2024, taking place October 24-27, 2024, in San Diego, Calif. Abstracts are available here. ADX-097, Q32 Bio’s lead product candidate from its tissue-targeted complement inhibitor platform, is a humanized anti-C3d mAb fusion protein being evaluated for the treatment of patients with renal diseases associated with increased complement activation.

“We look forward to presenting our promising clinical data at ASN Kidney Week 2024 that supports the continued advancement of ADX-097, our novel tissue-targeted inhibitor of complement activation designed to inhibit complement in the diseased tissue and minimize systemic complement blockade,” said Shelia Violette, Ph.D., Chief Scientific Officer of Q32 Bio. “In our Phase 1 clinical trial, ADX-097 was observed to be generally well-tolerated with desirable pharmacokinetics and pharmacodynamics (PK/PD) properties. We believe ADX-097 has the potential to achieve relevant complement inhibition directly in the tissue while sparing systemic activity, with the goal of addressing limitations of the currently available systemic approaches, including infection risk and the need for high drug doses and frequent administration to achieve therapeutic levels of complement inhibition.”

“These first-in-human data for ADX-097 that we will share at Kidney Week demonstrate the potential of our novel and differentiated approach to inhibiting the complement system, a validated biologic target,” said Jodie Morrison, Chief Executive Officer of Q32 Bio. “We remain focused on advancing our pipeline of programs targeting the immune system for the treatment of autoimmune and inflammatory diseases, including ADX-097 in two Phase 2 clinical trials.”

Abstract Title: ADX-097, a Tissue-Targeted Complement Inhibitor for the Treatment of Renal Diseases: Phase 1 Results in Healthy Participants and Model-Informed Phase 2 Dose Selection
Presenter: Dr. Bernd Jilma, M.D., Professor, Department of Clinical Pharmacology, Medical University of Vienna, Austria

Date & Time: Saturday, October 26, 2024, from 10:00 a.m. to 12:00 p.m. PT
Session Type: Poster
Session Title: C3G, TMA, MGRS, Amyloidosis, and More
Abstract ID: 4123429

Summary:

• ADX-097, a C3d mAb – fH fusion protein, was designed to inhibit complement in the diseased kidney while avoiding systemic blockade, providing the potential for an enhanced activity and safety profile. In a Phase 1 ascending dose clinical study of ADX-097 in healthy volunteers, ADX-097 demonstrated a favorable safety profile and desired PK/PD properties, supporting a Phase 2 dose that is predicted to provide tissue inhibition of complement in glomerular diseases while sparing systemic complement activity.

About ADX-097

ADX-097, the lead product candidate from Q32 Bio’s tissue-targeted complement inhibitor platform, is a humanized anti-C3d mAb fusion protein. ADX-097 is designed to restore complement regulation—an integral part of the innate immune system—through a novel, tissue-targeted mechanism. Q32 Bio is currently evaluating ADX-097 in an open-label Phase 2 renal basket clinical trial and is planning to evaluate ADX-097 in a Phase 2 clinical trial in ANCA-Associated Vasculitis (AAV).

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.
