Biologic Agents for the Treatment of Chronic Rhinosinusitis With Nasal Polyps

BACKGROUND: Chronic rhinosinusitis with nasal polyposis is a complex inflammatory disorder, which is often recalcitrant to medical and surgical management. Recently, biologic agents have been studied as an adjunct treatment for this patient population. OBJECTIVE: The purpose of this study is to examine the role of biologic agents for chronic rhinosinusitis patients by reviewing literature and clinical trials. METHODS: A comprehensive review of literature and clinical trials-both recently completed and ongoing-was undertaken to examine up-to-date evidence of current biologic therapy and its role in chronic rhinosinusitis patients-including anti-IgE, anti-IL-4, anti-IL-5, anti-IL-13, and GATA-3 DNAzyme. RESULTS: Specific biologic agents discussed include omalizumab, reslizumab, mepolizumab, benralizumab, dupilumab, and Hgd40/SB010. Risks, side effects, and administration information are also reviewed. An algorithm for the use of biologics in patients with chronic rhinosinusitis with nasal polyposis is proposed. CONCLUSION: These treatments have promising results and may prove to be an important adjunct for patients with recalcitrant sinus disease.
