BackgroundLong-term maintenance treatment of gastroesophageal reflux disease (GERD) is important to prevent relapse. Proton-pump inhibitors (PPIs) are used for both treatment and maintenance therapy of GERD. Recently, a potassium-competitive acid blocker vonoprazan was launched in Japan. We evaluated the comparative efficacy of vonoprazan and other PPIs for GERD maintenance.MethodsA systematic literature search was performed using MEDLINE and Cochrane Central Register of Controlled Trials. Double-blind randomized controlled trials (RCTs) of PPIs, vonoprazan, and placebo for GERD maintenance published in English or Japanese were selected. Among them, studies conducted at the recommended dose and for the recommended use, and containing information on maintenance rate based on endoscopic assessment, were included. The comparative efficacies of treatments were estimated by performing a Bayesian network meta-analysis, which assessed the consistency assumption. Outcomes were number or rate of patients who maintained remission.ResultsOf 4001 articles identified, 22 RCTs were eligible for analysis. One study published as an abstract was hand-searched and added. The consistency hypothesis was not rejected for the analysis. The odds ratio of vonoprazan 10mg to each PPI was 13.92 (95% credible interval [CI] 1.70-114.21) to esomeprazole 10mg; 5.75 (95% CI 0.59-51.57) to rabeprazole 10mg; 3.74 (95% CI 0.70-19.99) to lansoprazole 15mg; and 9.23 (95% CI 1.17-68.72) to omeprazole 10mg.ConclusionsThe efficacy of vonoprazan in GERD maintenance treatment may be higher than that of some PPIs. However, a direct comparison of vonoprazan and PPIs is required to confirm these effects.
