Plain Language Summary of Publication: What is the effect of the medicine vibegron in the treatment of overactive bladder in patients with and without bladder leakage?

Abstract

What is this summary about? People with overactive bladder need to use the bathroom many times a day to urinate (pee). This need may often be sudden and may cause some people with overactive bladder to have accidental bladder leakage. The EMPOWUR trial looked at how well a medicine called vibegron worked to help people with overactive bladder. The study also included another drug that was already available for treating overactive bladder called tolterodine and a pill with no medicine called a placebo. Both vibegron and tolterodine were compared with placebo. Participants had improvements in their overactive bladder symptoms after taking either vibegron or tolterodine compared to placebo. The medicine vibegron was approved in 2020 by the US Food and Drug Administration (also called the FDA) to treat overactive bladder. Researchers next wanted to see how well vibegron worked in people from the EMPOWUR trial split into 2 groups. One group was made of participants with overactive bladder who have accidental leakage. The second group was made of participants with overactive bladder who do not have accidental leakage. This is a plain language summary of the study of how well vibegron works for those 2 groups from the EMPOWUR study that was published in the International Journal of Clinical Practice. What were the results? Study participants who took vibegron needed to pee fewer times per day. The number of times they had little warning before the need to pee was also lower. The results were the same for study participants who did and did not have accidental leakage related to overactive bladder. What do the results mean? This study suggests that vibegron can improve symptoms in people with overactive bladder whether or not they have accidental bladder leakage.
