Background: Several promising clinical trials have demonstrated the effects of type 2 biologics compared with placebos in chronic rhinosinusitis with nasal polyps (CRSwNP). However, there are no head-to-head randomized controlled trials (RCTs) between the biologics.
Objective: To compare the efficacy and safety of different biologics used for the treatment of CRSwNP.
Methods: We systematically identified RCTs investigating the effects of biologics for CRSwNP. Primary outcomes were nasal polyp score (NPS), nasal congestion severity, and serious adverse events. Secondary outcomes included the 22-item Sino-Nasal Outcome Test (SNOT-22) score, loss of smell severity, the University of Pennsylvania Smell Identification Test score, and the Lund-Mackay computed tomography score. Bucher indirect treatment comparison (ITC) was used to compare the outcome parameters.
Results: Seven RCTs (Bachert 2017, OSTRO, POLYP 1, POLYP 2, SINUS-24, SINUS-52, and SYNAPSE) involving 1913 patients and 4 biologics (benralizumab, dupilumab, mepolizumab, and omalizumab) were included for ITC. Dupilumab presented better effects in decreasing NPS and nasal congestion severity compared with the other 3 biologics at 24 weeks of the treatment and at the end of follow-up (more than 48 weeks). Benralizumab was the least effective in reducing nasal congestion severity and SNOT-22 score at 24 weeks. No significant differences were observed between the effects of the other biologics.
Conclusion: Our current findings suggest that dupilumab exhibits the best efficacy and safety for the treatment of CRSwNP.
