Introduction: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a heterogeneous disease. High proportions of patients with CRSwNP characterized by type 2 inflammation fail to gain adequate control with conventional treatment. The application of biologics in clinics and assessments of novel biologics in clinical trials are blooming in expectations to fulfill the unmet medical needs of patients with CRSwNP with type 2 inflammation.
Areas covered: After an extensive search of PubMed, Medline, and EMBASE for the most recent evidence, we thoroughly summarize current advances in biological therapies for treating patients with CRSwNP.
Expert opinion: In recent years, biological therapy has been in the spotlight in clinical studies on CRSwNP. Biologics have proven to be efficacious in reducing nasal polyp size, alleviating CRSwNP-related symptoms, improving quality of life, and reducing the need for systemic corticosteroids or endoscopic sinus surgery for nasal polyps. The considerable efficacy and safety profile of biologics has offered patients with refractory CRSwNP another treatment option. However, some concerns remain to be addressed. Aspects such as the position of biological therapy in the management of CRSwNP, traits of patients suitable for certain biologics, etc. necessitate efforts to elucidate these unknowns in order to provide patients with tailored therapy.
