TQC2731 injection is a humanized monoclonal antibody that targets Thymic Stromal Lymphopoietin (TSLP), blocks the TSLP pathway, and inhibits the production of downstream cytokines, thereby exerting anti-inflammatory effects. The purpose of this study is to evaluate the efficacy and safety of TQC2731 injection in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).
