Objective:
Vibegron is a new kind of β3-adrenergic receptor agonist. We performed a systematic review and pooled analysis to assess the efficacy, safety, and tolerability of Vibegron for treating overactive bladder (OAB).
Methods:
MEDLINE, the Cochrane Controlled Trial Register and EMBASE were used to pick out randomized controlled trials (RCTs) of Vibegron in treating OAB. The reference lists of the retrieved articles were also studied. We used RevMan version 5.3.0. to analyze the data.
Results:
Three high-quality RCTs involving a total of 2120 OAB patients were adopted in the systematic review and pooled analysis. The mean number of micturitions episodes/d (mean difference [MD] = -0.77; 95% confidence interval [CI] = -1.0 to -0.55; P < .00001); the mean number of urgency episodes/d (MD = -0.77; 95% CI = -1.03 to -0.52; P < .00001); mean number of urgency incontinence episodes/d (MD = -0.50; 95% CI = -0.64 to -0.35; P < .00001); mean number of incontinence episodes/d (MD = -0.45; 95% CI = -0.66 to -0.25; P < .0001); and mean volume voided/micturition (MD = 22.22; 95% CI = 17.36 to 27.07, P < .00001) showed that Vibegron was more efficacy in treating OAB than placebo. Dry mouth, drug-related treatment-emergent adverse event (TEAE), serious adverse event (SAE), and discontinuations due to adverse event (AE) suggested that Vibegron was well tolerated.
Conclusions:
Our systematic review and pooled analysis demonstrate that Vibegron 75 mg or 100 mg/d statistically significant improved OAB symptoms. The treatment was well-tolerated, with a favorable safety profile.
