Meta-Analysis Review
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; I = 0), iTNSS (MD = - 1.05; [95% CI - 1.44 to - 0.67]; P < 0.01; I > 50%), rTOSS (MD = - 0.50; [95% CI - 0.72 to - 0.29]; P < 0.01; I = 0), iTOSS (MD = - 0.64; [95% CI - 1.02 to - 0.26]; P < 0.01; I > 50%), PNSS (MD = - 1.01; [95% CI - 1.32 to - 0.69]; P < 0.01; I = 22.13%), RQLQ (MD = - 0.43; [95% CI - 0.57 to - 0.30]; P < 0.01; I = 0%) and RCAT (MD = 1.94; [95% CI 1.43-2.45]; P < 0.01; I = 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 help to improve patients' quality of life and rhinitis control in the long run.

BACKGROUND
Allergic conjunctivitis (AC) is a multifactorial and common type of ocular surface disease that affects many people. The quality of life for AC patients can be significantly decreased caused by symptoms of ocular itching, swelling, redness, and tearing. Topical antihistaminics, mast cell stabilizers, non-steroidal anti-inflammatory drugs (NSAIDs), and steroids have been widely used to treat AC. Many clinical trials have indicated that olopatadine hydrochloride eye drops can provide quick relief of symptoms and signs. The purpose of this review is to evaluate systematically the effectiveness of olopatadine hydrochloride eye drops for treating AC.
METHODS
A systematic review of all of the randomized controlled trials on the effectiveness and safety of olopatadine hydrochloride eye drops for AC will be conducted. We will search PubMed, Web of Science (WOS), EMBASE (OVID), the Cochrane Library, Google Scholar, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal database (VIP), Wanfang Database, and CBM, from the database inception date to October 31, 2019. There are no language or publication status restrictions. Registers of clinical trials, potential gray literature, reference lists of studies, and conference abstracts will also be searched. Two reviewers will independently read the articles, extract the data information, and assess the quality of the studies. Data will be synthesized by a heterogeneity test. The primary outcomes include the main symptom and sign scores before and after treatment, the eye redness index, the presence of eosinophils in the conjunctival scraping. Quality of life, the total treatment efficacy, and safety will be evaluated as the secondary outcomes. RevMan V.5.3 software will be used for the meta-analysis.
RESULTS
The study will provide an objective and normative systematic review to evaluate the effectiveness and safety of olopatadine hydrochloride eye drops for the treatment of AC.
CONCLUSION
Our review will provide useful information to judge whether olopatadine hydrochloride eye drops is an effective intervention for patients with AC.
ETHICS AND DISSEMINATION
It is not necessary to obtain ethical approval as participants are not involved patients. The protocol and results will be published in a peer-reviewed journal. The systematic review will also be disseminated electronically and in print to help guide health care practice and policy.
