| Abstract |
Omalizumab is a recombinant DNA-derived humanized monoclonal antibody targeting free immunoglobulin E. In the omalizumab phase III studies for chronic rhinosinusitis with nasal polyp (CRSwNP), a clinically relevant reduction of the nasal polyp score (NPS) was observed leading to improved SinoNasal Outcome Test-22 (SNOT-22). In the extension study, sustained or further improvement of symptoms and NPS reduction were observed up to 52 weeks. Real-world data is needed to establish effectiveness in uncontrolled severe CRSwNP, but so far, data on long-term omalizumab treatment is sparse . |
