Clinical Trial on the Preventive Effect of Intravaginal Prasterone on Recurrent Urinary Tract Infections in Postmenopausal Women

Menopause Clinical Trial

Official title: A Randomized, Double-blind, Placebo-controlled Trial on the Preventive Effect of Intravaginal Prasterone (DHEA, Intrarosa®) on Recurrent Urinary Tract Infections in Women With Genitourinary Syndrome of Menopause

Status Withdrawn

Clinical Trial Summary

Urinary tract infections (UTIs) are bothersome and more likely to occur in postmenopausal women. Frequent UTIs, as well as other problems with the urinary and genital systems such as painful sex and urinary frequency/urgency, are part of a symptom complex called genitourinary syndrome of menopause (GSM). Prasterone (Intrarosa®) is a man-made steroid that helps with painful sex in postmenopausal women. Because previous studies have shown prasterone to help with other GSM problems, this study was designed to investigate if prasterone used in the vagina decreases the number of UTIs in postmenopausal women.

Clinical Trial Description

Urinary tract infections (UTIs) are costly contributing to more than 8 million ambulatory visits (84% women) in the United States in 2007. Recurrent urinary tract infections (rUTIs) are UTIs diagnosed on at least 2 urine cultures in 6 months, or at least 3 in 1 year. The incidence of rUTIs increases in menopause with an estimated 10-15% of women > 60 years old having rUTIs. rUTIs contribute to a constellation of bothersome genitourinary symptoms in some postmenopausal women called genitourinary syndrome of menopause (GSM). Thus, menopause, rUTIs, and GSM are intimately linked.

Prasterone (Intrarosa®) is a synthetic version of the steroid, dehydroepiandrosterone (DHEA), approved by the US Food and Drug Administration in 2016 for the treatment of moderate to severe dyspareunia due to GSM. Large, prospective studies have shown prasterone to safely decrease vaginal pH, decrease parabasal cells, increase superficial cells, and decrease symptoms related to atrophy like dyspareunia in women with GSM. Given prasterone's favorable treatment effects on some GSM symptoms, investigation of prasterone as a possible treatment option for rUTIs in the setting of GSM is warranted.

This is a single center, double-blind, placebo-controlled, randomized trial comparing the efficacy of nightly intravaginal prasterone for 24 weeks to intravaginal placebo in decreasing rUTIs in women with GSM. The study hypothesis is that intravaginal prasterone decreases UTI incidence in women with GSM compared to placebo. ;
