ABSTRACT Introduction: Chronic rhinosinusitis with nasal polyposis (CRSwNP) poses a significant healthcare challenge, with diminished quality of life for patients and high costs and resource utilization for disease management. The understanding of CRSwNP pathophysiology has progressed with identification of various inflammatory biomarkers and subsequent development of monoclonal antibodies that target the underlying mechanisms of inflammation. Areas covered: Omalizumab is a biologic agent for CRSwNP treatment that targets immunoglobulin (Ig)-E. The US FDA has approved the use of omalizumab as an add-on biologic therapy for nasal polyposis in December 2020. Two Phase III clinical trials, POLYP 1 and POLYP 2, have shown that omalizumab improves both subjective patient-reported outcomes and objective physician-evaluated metrics for CRSwNP. Ongoing studies are still exploring the efficacy, safety, and cost-effectiveness of biologics for CRSwNP. Expert opinion: Biologics will continue develop as a viable management option for CRSwNP. Omalizumab is regarded as a promising addition to current treatment strategies for refractory disease.
