About MG-K10

MG-K10 is an innovative long-acting anti-IL-4Rα humanized monoclonal antibody that simultaneously blocks the signaling of key type 2 inflammatory cytokines IL-4 and IL-13. Following Fc mutation, MG-K10 allows long dosing interval owing to its prolonged half-life, and it is expected to be the first long-acting anti-IL-4Rα monoclonal antibody marketed in China. The indication including AD, asthma, rhinosinusitis, prurigo nodularis, esophagitis, COPD and so on. The Phase II clinical results of MG-K10 in both AD and asthma confirmed that it has the potential to be Best-in-Class. In the Phase II moderate-to-severe AD trial, MG-K10 highly improved patients’ clinical signs and quality of life, while in the Phase II moderate-to-severe asthma trial, MG-K10 significantly improved lung function and clinical symptoms. While other launched anti-IL-4Rα therapeutics need to be dosed Q2W, MG-K10 is highly effective and well tolerated dosed Q4W. MG-K10 is in Phase III in AD, asthma and prurigo nodularis.
