What this Trial Is About
Researchers are studying TQC2731 injection, a humanized monoclonal antibody that targets Thymic Stromal Lymphopoietin (TSLP) to block its pathway and reduce inflammation. This clinical trial focuses on patients with chronic rhinosinusitis with nasal polyps (CRSwNP) to evaluate the safety and effectiveness of TQC2731 injection. Participants will receive either TQC2731 injection or a placebo in treatment cycles lasting 4 weeks. The study is randomized, double-blind, and placebo-controlled, with repeated treatment cycles. The effects on nasal polyp size and nasal congestion will be assessed over a 24-week period, with additional measures taken up to 60 weeks. During the trial, participants will undergo nasal endoscopy to score nasal polyps and congestion, complete symptom questionnaires, and have blood and nasal tissue samples collected at various points. Safety monitoring includes tracking adverse events and immune response tests. The study duration extends to 60 weeks to evaluate long-term outcomes and treatment impact.
