ABSTRACT
PURPOSE: GSP301 is a fixed-dose combination of olopatadine hydrochloride (antihistamine) and mometasone furoate (corticosteroid). This meta-analysis aims to evaluate the efficacy and safety of GSP301 in the treatment of allergic rhinitis.
METHODS: A systematic review and meta-analysis were conducted. The data were collected from PubMed, Cochrane Central Register of Controlled Trials and Embase databases till June 2021. In patients with AR, short-term (2/6 weeks) and long-term (52 weeks) effects of GSP301 were assessed. Average morning and evening 12-h reflective total nasal symptom score (rTNSS), instantaneous total nasal symptom score (iTNSS), reflective total ocular symptom score (rTOSS), instantaneous total ocular symptom score(iTOSS), Physician-assessed nasal symptom score (PNSS), rhinoconjunctivitis quality of life (RQLQ) , rhinitis control assessment test (RCAT) and adverse events (AEs) were measured.
RESULTS: Five randomized controlled trials were included. GSP301 showed greatly improvement in rTNSS (MD = - 0.99; [95% CI - 1.19 to - 0.79]; P < 0.01; I2 = 0), iTNSS (MD = - 1.05; [95% CI - 1.44 to - 0.67]; P < 0.01; I2 > 50%), rTOSS (MD = - 0.50; [95% CI - 0.72 to - 0.29]; P < 0.01; I2 = 0), iTOSS (MD = - 0.64; [95% CI - 1.02 to - 0.26]; P < 0.01; I2 > 50%), PNSS (MD = - 1.01; [95% CI - 1.32 to - 0.69]; P < 0.01; I2 = 22.13%), RQLQ (MD = - 0.43; [95% CI - 0.57 to - 0.30]; P < 0.01; I2 = 0%) and RCAT (MD = 1.94; [95% CI 1.43-2.45]; P < 0.01; I2 = 0%) in the short term. No statistical difference was observed in the outcome of long-term PNSS, RQLQ and RCAT.
CONCLUSION: GSP301 is a safe and well-tolerated medication. It showed short-term benefits for seasonal and perennial AR, but may not h elp to improve patients' quality of life and rhinitis control in the long run.
