SPS commentary:
Vibegron is an agonist of beta-3 adrenergic receptors which enhances bladder relaxation. In the Phase III EMPOWUR trial it was shown to decrease daily urge urinary incontinence episodes (by a mean of 2.0 episodes/day versus 1.4 for placebo; p<0.0001) and daily micturitions (by an adjusted mean of 1.8 episodes/day versus 1.3 for placebo; p<0.001). Although tolterodine 4mg was also used as a comparator, the formal efficacy analysis was the comparison of vibegron and placebo.
