A Study of the Pharmacokinetics and Pharmacodynamics of Vibegron (MK-4618) in Women With Overactive Bladder (MK-4618-004)
A Placebo and Active-Comparator Controlled Multiple-Dose Study to Evaluate the Pharmacokinetics and Pharmacodynamics of MK-4618 in Patients With Overactive Bladder
The study is designed to investigate the effects of the investigational drug vibegron (MK-4618) compared to placebo on maximum urinary bladder capacity in women with overactive bladder. The study will also evaluate the safety and tolerability of multiple oral doses of vibegron in women with overactive bladder. Overactive bladder is best described as urgency and frequency of urination, with or without involuntary urination and/or the need to awaken during the night to urinate.
The primary efficacy hypothesis is that vibegron is superior to placebo with respect to change from baseline in maximum cystometric capacity at 2 hours postdose on Day 7 (i.e., steady state) in participants with overactive bladder. A true mean increase (vibegron/placebo) of 25% in bladder volume is expected.
The primary safety hypothesis is that administration of multiple oral doses of vibegron is sufficiently well-tolerated in participants with overactive bladder, based on assessment of clinical and laboratory adverse experiences, to permit continued clinical investigation.

Intervention / Treatment |
---|---|
Experimental: Vibegron 100 mg + tolterodine ER 4 mg → placebo
During Treatment Period 1, participants will receive 7 days of once-daily vibegron 100 mg and tolterodine extended-release (ER) 4 mg.
Participants will then complete a 2-week single-blind double-dummy placebo washout period prior to Treatment Period 2. During Treatment Period 2, participants will receive 7 days of once-daily placebo to match vibegron and placebo to match tolterodine ER.
