Innovent Biologics, Inc. (Innovent) (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of oncology, metabolic, autoimmune, ophthalmology and other major diseases, announces that the first participant has been dosed in Australia in a first-in-human (FIH) phase 1 clinical trial of IBI3002, a global first-in-class bispecific antibody targeting Interleukin 4 receptor α (IL-4Rα) and thymic stromal lymphopoietin (TSLP).

This FIH study (NCT06213844) is a randomized, double-blind, placebo-controlled, single ascending dose (SAD) study to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) (only in participants with asthma) of IBI3002 in healthy participants and participants with mild to moderate asthma, and to support further global clinical development of IBI3002.

IBI3002 is a humanized bispecific antibody targeting cell surface IL-4Rα and the alarmin cytokine TSLP, discovered and developed by Innovent for the treatment of inflammatory diseases, including asthma. IL-4 receptors mediate the IL-4 signaling (both type 1 and type 2) and the IL-13 signaling (type 2). Both cytokine signaling pathways play key roles in the pathophysiology of type 2 (T2) inflammatory disorders1. TSLP is an epithelial cell-derived alarmin cytokine and triggers both T2 and non-T2 inflammation in asthma2.

IBI3002 has high-efficient dual-blocking function on both IL-4Rα and TSLP. In-vitro assays have shown superiority over the marketed monoclonal antibodies to respective target. By targeting both IL-4Rα and TSLP, IBI3002 is hypothesized to have potential effect in suppressing T2 and non-T2 inflammation. The potential synergistic effect in suppressing T2 inflammation is believed to be the basis of its superior efficacy in the treatment of T2 inflammatory disorders.

Dr. Lei Qian, Vice President of Clinical Development at Innovent, stated, “In the last few decades, knowledge about both pathophysiological mechanisms, clinical phenotypes and therapeutic options for asthma have significantly increased. In particular, the introduction of biologics for severe asthma paved the way to a true revolution in the field of asthma management, by potentially allowing a precision medicine approach. Targeting specific steps of the immune-inflammatory cascade through highly selective drugs represents a true revolution in the field of severe asthma management, and brings with it the potential of achieving optimal disease control in different severe asthma inflammatory phenotypes. We are looking forward to the development of this molecule in asthma and other inflammatory diseases.”
