Effects of vibegron on ambulatory blood pressure in patients with overactive bladder: results from a double-blind, placebo-controlled trial
Abstract
Supplemental Digital Content is available in the text. Objectives To characterize the blood pressure (BP) profile of the new β3-adrenergic receptor agonist, vibegron, in patients with overactive bladder. Methods Patients were randomized to once-daily vibegron 75 mg or placebo for 28 days and underwent ambulatory BP monitoring. The primary endpoint was change from baseline (CFB) to day 28 in mean daytime ambulatory systolic BP (SBP). Secondary endpoints were CFB in mean 24-h SBP and in mean daytime and mean 24-h ambulatory diastolic BP (DBP) and heart rate (HR). Safety was assessed through adverse event reporting. Results Of 214 patients randomized, 96 receiving vibegron and 101 receiving placebo had evaluable baseline and day 28 measurements. Overall, 39.6 and 30.7% of patients receiving vibegron and placebo, respectively, had preexisting hypertension. The least squares mean difference (LSMD; 90% confidence interval) between vibegron and placebo in CFB in mean daytime SBP was 0.8 (–0.9, 2.5) mmHg. LSMD in CFB in mean daytime DBP and HR was 0.0 mmHg and 0.9 bpm, respectively. No significant differences between treatments were seen in CFB in mean 24-h SBP (LSMD, 0.6 mmHg), DBP (–0.2 mmHg) or HR (1.0 bpm). The most common treatment-emergent adverse event was hypertension, with rates comparable between groups [vibegron: n = 5 (4.7%); placebo: n = 4 (3.7%)]. One patient receiving vibegron took a prohibited medication (phentermine) known to increase BP. Conclusions Once-daily…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 214 participants or records.
