Innovent Biologics Inc. announced the presentation of new preclinical study results for two investigational therapies, IBI3011 and IBI3034, at the 2025 American College of Rheumatology $(ACR)$ Annual Meeting. IBI3011 is a humanized monoclonal antibody targeting IL-1RAP, designed to inhibit inflammation driven by IL1α, IL1β, and IL36, and demonstrated efficacy in animal models of gout and arthritis as well as favorable pharmacokinetic and safety profiles in monkeys. A high-concentration formulation of IBI3011 has been developed to allow subcutaneous administration, and its IND application has been approved by China's National Medical Products Administration (NMPA) for acute gouty arthritis. IBI3034, a TACI/BCMA chimeric fusion protein, is currently undergoing IND-enabling studies for B cell-mediated autoimmune diseases. The results were showcased as poster presentations at the ACR 2025 conference.
