NCT05428410

Brief Summary

The prevalence of chronic rhinosinusitis in China is about 8%, and some patients still suffer from recurrences after surgery and drug treatment. Monoclonal antibody is considered to be a new drug strategy that can significantly improve the control rate of such patients, but there is a lack of markers to guide the selection of monoclonal antibodies. The price of monoclonal antibody is expensive, which calls for screening markers for predicting the efficacy of monoclonal antibody and precisely implementing this treatment strategy. In addition, it can also improve the quality of life of patients and reduce the social and economic burden. Beijing Tongren Hospital, Capital Medical University recently completed a randomized, double-blind, placebo-controlled, phase II clinical study which included multiple subcutaneous administration of CM310 recombinant humanized monoclonal antibody injection in patients with chronic sinusitis and nasal polyps to evaluate the efficacy and safety as well as the pharmacokinetics, pharmacodynamics, immunogenicity and preliminary efficacy(NCT04805398). The therapeutic target of CM310 recombinant humanized monoclonal antibody injection is IL-4R. The unblinded data showed significant differences in the efficacy of the subjects and we started the investigator-initiate trial (IIT) study aiming at investigating the remaining samples of the project and carrying out a biomarker study to screen and predict the efficacy of IL-4R monoclonal antibody.
