This clinical trial is focused on studying the effects of a medication called Dupilumab on a condition known as chronic rhinosinusitis with nasal polyps (CRSwNP). CRSwNP is a long-term condition where the sinuses become inflamed, and small growths called polyps form in the nasal passages. The study will compare the effects of Dupilumab, which is given as a subcutaneous injection, to a placebo. Dupilumab is also known by its code names REGN668 and SAR231893.
The purpose of the study is to explore how Dupilumab can help restore the barrier function in the airways of patients with CRSwNP. Participants will receive either Dupilumab or a placebo in addition to their standard care for CRSwNP and/or asthma. The study will last for 24 weeks, during which time the effects of the treatment on nasal tissue and other health markers will be monitored. This includes looking at changes in certain proteins and genes in the nasal tissue, as well as other health indicators in the blood.
Throughout the study, participants will have regular check-ups to assess their condition and the impact of the treatment. The study aims to provide insights into how Dupilumab can improve the symptoms and quality of life for people with CRSwNP. Participants will be monitored for changes in their symptoms and overall health, with the goal of understanding the potential benefits of adding Dupilumab to their treatment plan.
