Efficacy and Safety of Vibegron for Persistent Symptoms of Overactive Bladder in Men Being Pharmacologically Treated for Benign Prostatic Hyperplasia: Results From the Phase 3 Randomized Controlled COURAGE Trial.

PURPOSE: Efficacy and safety of vibegron, a ß3-adrenergic receptor agonist, was assessed among men with symptoms of overactive bladder (OAB) receiving pharmacologic treatment for benign prostatic hyperplasia (BPH) in a phase 3 randomized controlled trial. MATERIALS AND METHODS: Men ≥ 45 years with OAB symptoms and BPH, treated with α-blocker with/without 5α-reductase inhibitors, were randomized 1:1 to vibegron or placebo for 24 weeks. Coprimary end points were change from baseline at week 12 in mean daily micturitions and urgency episodes. Secondary end points were change from baseline at week 12 in mean nightly nocturia and daily urge urinary incontinence episodes, International Prostate Symptom Score‒storage score, and volume voided per micturition. Safety was evaluated via adverse events (AEs). RESULTS: Of 1105 participants randomized, 965 (87.3%) completed the trial. At week 12, vibegron was associated with significant reductions vs placebo in daily micturitions (least squares mean difference [95% CI], -0.74 [-1.02, -0.46]; P < .0001) and urgency episodes (-0.95 [-1.37, -0.54]; P < .0001). Vibegron was also associated with significant improvements vs placebo at week 12 in nocturia episodes (least squares mean difference, -0.22 [-0.36, -0.09]; P = .002), urge urinary incontinence episodes (-0.80 [-1.33, -0.27]; P = .003), International Prostate Symptom Score‒storage scores (-0.9 [-1.2, -0.6]; P < .0001), and volume voided (15.07 mL [9.13-21.02]; P < .0001). AE rates were similar in vibegron (45.0%) and placebo (39.0%) arms; AEs occurring in ≥ 2% of participants were hypertension (9.0% vs 8.3%), COVID-19 (4.0% vs 3.1%), UTI (2.5% vs 2.2%), and hematuria (2.0% vs 2.5%). CONCLUSIONS: In this trial, vibegron met all primary and secondary end points, and was safe and well tolerated in men with OAB symptoms and pharmacologically treated BPH.

A Plain Language Summary on the Effect of the Medication Vibegron on Blood Pressure and Heart Rate in People With Overactive Bladder.

WHAT IS THIS SUMMARY ABOUT?: This is a plain language summary of an article originally published in the journal Blood Pressure Monitoring. Vibegron is a medicine that was approved by the US Food and Drug Administration (also called FDA) in 2020 for treatment of overactive bladder, a condition that causes a frequent and urgent need to urinate. This study took place before the medicine was approved to look at whether vibegron affects blood pressure or heart rate. WHAT WERE THE RESULTS?: A total of 214 patients with overactive bladder took part in the study. 108 patients took vibegron for 28 days, and 106 took placebo for 28 days. A placebo is a pill with no medicine in it. Their blood pressure was measured on the first day and the last day. A meaningful increase in blood pressure is when a patient's average blood pressure measurements changed by 3.5 mmHg or more. Patients with overactive bladder who took a 75 mg dose of vibegron once daily had no meaningful increase in blood pressure or heart rate. This included people who were already taking medication for their high blood pressure. WHAT DO THE RESULTS MEAN?: This study suggests that patients can use vibegron without concern that it may meaningfully raise blood pressure or heart rate.

Plain language summary: does treatment with vibegron result in improvements in overactive bladder (OAB) symptoms that are meaningful to people with OAB?

What is this summary about? This is a plain language summary of an article published in the journal Advances in Therapy. In 2020, the US Food and Drug Administration (also called the FDA) approved a medicine called vibegron to treat overactive bladder, also called OAB. The key results used to approve vibegron were from the EMPOWUR study. In the EMPOWUR study, participants who took vibegron had fewer urination episodes, urgency episodes, and bladder leaks each day than those who took a pill containing no medicine, called a placebo. At the end of the study, participants also rated how much their overactive bladder symptoms changed overall during EMPOWUR by responding to a survey. Many participants rated their overactive bladder symptoms as improved overall. This study asked if improvements in the number of urination episodes, urgency episodes, and bladder leaks caused by urgency were associated with feeling better overall. This study also looked at how many participants in the EMPOWUR study had improvements in the number of urination episodes, urgency episodes, and bladder leaks that were big enough to matter. A separate group of people with overactive bladder were asked about the magnitude of improvements that would be important to them. This group had not participated in the EMPOWUR study. What were the results? EMPOWUR participants who reported that taking medicine resulted in their overactive bladder symptoms getting better overall also generally reported fewer daily urinations, urgency episodes, and bladder leaks after treatment. Many had changes in their symptoms that were meaningful. Meaningful was defined for each symptom as: at least 15% fewer urinations, 50% fewer urgency episodes, and 75% fewer bladder leaks. Participants who received vibegron had meaningful reductions in the daily number of episodes of urination, urgency, and bladder leaks more often than those who received the placebo (pill with no active medicine). People with overactive bladder who did not participate in the study were interviewed and said that improvements to those symptoms, similar to those seen in the EMPOWUR study, would be important to them. What do the results mean? This study suggests that the results we measured in the EMPOWUR study may also reflect changes in overactive bladder symptoms that are big enough to be important to people with overactive bladder. Many participants who took vibegron in the EMPOWUR study felt that it helped to improve their individual overactive bladder symptoms. This may also help improve quality of life of participants.

Plain language summary of safety and symptom improvement with vibegron in people with overactive bladder: results from the EMPOWUR study.

What is this summary about? This is a plain language summary of an article originally published in the Journal of Urology. Overactive bladder (also called OAB) has been treated with the same type of medicine for more than 40 years. Vibegron is in a newer class of medicine for treating overactive bladder called beta-3 adrenergic receptor agonists. The EMPOWUR study was a phase 3 clinical trial that looked at whether vibegron was safe and improved symptoms in people with overactive bladder. Vibegron was approved by the US Food and Drug Administration (also called the FDA) based in part on the results of this study. What were the results? Participants of the EMPOWUR study who took vibegron showed an improvement in their overactive bladder symptoms. These symptoms include the number of urinations (peeing), the urgent need to urinate, and accidental urination (bladder leaks). After 12 weeks, participants who took vibegron had significantly greater improvements than participants who took placebo. What do the results mean? This study suggests that vibegron could safely improve symptoms in people with overactive bladder. Clinical Trial Registration: NCT03492281 (ClinicalTrials.gov).

CONTROL: A randomized phase 2 study of obeticholic acid and atorvastatin on lipoproteins in nonalcoholic steatohepatitis patients.

BACKGROUND & AIMS: Nonalcoholic steatohepatitis (NASH) is a chronic and severe form of nonalcoholic fatty liver disease that can progress to cirrhosis and hepatocellular carcinoma and is a risk factor for cardiovascular disease. Although NASH has no approved treatments, obeticholic acid (OCA), a synthetic bile acid and farnesoid X receptor (FXR) agonist, was shown to improve histological features of NASH and fibrosis. Considering that FXR activation influences plasma lipoprotein concentrations, the Combination OCA aNd sTatins for monitoRing Of Lipids (CONTROL) study evaluated how statins can regulate lipoprotein metabolism with OCA treatment in patients with NASH. METHODS: This randomized, double-blind, placebo-controlled, phase 2 study began with a 5-week screening/statin washout; 84 patients with NASH were randomly assigned (1:1:1:1) to receive placebo or 5 mg, 10 mg or 25 mg OCA once daily during the 16-week double-blind phase. Concurrent once daily atorvastatin (10 mg/days) was initiated at Week 4 with subsequent titration. Enrolled patients had biopsy-confirmed diagnosis of NASH with no evidence of hepatic decompensation. Plasma was collected to analyse lipoprotein parameters. RESULTS: At Week 4, all OCA groups had an increase from baseline in mean low-density lipoprotein cholesterol (LDLc) and mean LDL particle concentration (LDLpc), mostly owing to large, less atherogenic LDLc particles. Atorvastatin 10 mg decreased LDLc and LDLpc levels below baseline in all OCA groups by Week 8; higher doses did not provide additional clinical benefits. CONCLUSIONS: The CONTROL study showed that OCA-induced increases in LDLc in patients with NASH were mitigated with atorvastatin. The combination of OCA and atorvastatin was generally safe and well tolerated (NCT02633956).
