Innovent Biologics Inc. has announced the successful dosing of the first participant in a Phase 1 clinical trial for IBI3011, a recombinant anti-human Interleukin 1 Receptor Accessory Protein (IL-1RAP) monoclonal antibody. IBI3011 is the first anti-IL-1RAP monoclonal antibody developed in China targeting inflammatory and autoimmune diseases, and preclinical data indicate it can significantly suppress gout flares in acute gouty arthritis models. The current trial is a single ascending dose study designed to evaluate the safety, tolerability, and pharmacokinetics of IBI3011 in both healthy volunteers and patients with gout flares. Additionally, Innovent highlighted promising Phase 2 results for IBI128 (tigulixostat), which were presented at APLAR 2025, demonstrating strong efficacy in reducing serum uric acid levels in patients with gout. The company plans to advance IBI128 to Phase 3 trials and continues to expand its pipeline for metabolic and autoimmune diseases.
