Trial or other data

Mar 20 · Data from PIII EMPOWUR trial published online in the J. of Urology. [16]
Mar 19 · Urovant announce PIII EMPOWUR trial meets co-primary endpoints at week 12, decreasing daily urge urinary incontinence and decreasing daily microuritions vs placebo. Full data will be presented at an upcoming medical conference [13].
Mar 18 · Pivotal, randomised, double-blind, placebo- and active comparator-controlled international PIII clinical trial EMPOWUR initiated. The EMPOWUR trial will evaluate safety and efficacy of vibegron in men and women with symptoms of overactive bladder. The study is expected to enroll approximately 1,400 pts who will be randomided to one of three groups for a 12-week treatment period: oral vibegron 75 mg once daily, oral placebo once daily or oral tolterodine ER 4 mg once daily. Eligible pts completing the initial 12-week blinded assessment can enroll in a 40-week double-blind extension study to evaluate the safety of longer-term treatment. The co-primary efficacy endpoints of the study are; change from baseline in the average number of micturitions per 24 hours and change from baseline in the average number of urge urinary incontinence (UUI) episodes per 24 hours in pts with an average of ≥ 1 UUI episodes per day prior to treatment.[10]
Dec 17 · Results are available for PIII study (NCT01314872) [8].
Jan 17 · No further development reported [7].
Jan 16 · No progress to PIII studies in EU or US, but PIII in Japan [5].
Oct 13 · A one-year extension trial to PIIb (NCT01314872) study completes. Patients who completed part one of the study were screened for the extension to assess the long-term safety and efficacy of MK 4618 [4].
Jan 11 · 2-part phase IIb worldwide trial to assess the safety and efficacy of once daily low-mid-high doses of MK 4618 compared with tolterodine ER in 1295 patients with overactive bladder (NCT01314872). [2]
