Brief Summary

This is a new application from the Menopause Strategies: Finding Lasting Answers for Symptoms and Health (MsFLASH) Clinical Trials network. Here we propose to conduct a large multicenter trial comparing two common treatments, a vaginal hormone tablet and an over-the-counter gel, with placebo to evaluate their effects on bothersome vaginal symptoms and sexual function, and to create a biorepository of specimens for future translational, mechanistic research on the etiology of vaginal symptoms.

Detailed Description

The Menopause Strategies: Finding Lasting Answers for Symptoms and Health (MsFLASH) Clinical Trials network was established in 2009. By the end of 2014, the network completed 4 clinical trials testing 7 interventions in approximately 1000 women ages 40-62 with vasomotor (VMS) and other menopause symptoms.

The current trial will evaluate a relatively understudied area of menopause - vaginal health and sexual function. This is a 3-arm, randomized, controlled, double-blind, clinical trial among postmenopausal women ages 45-70.

Our primary aim is to evaluate the effectiveness of ultra-low dose vaginal estradiol (Vagifem 10 mcg), non-hormonal hydrophilic non-prescriptive vaginal gel (Replens) and placebo in reducing the Most Bothersome Symptom (MBS) severity. Choices for MBS include vulvovaginal itching, pain, dryness, irritation, or pain with penetration.

Secondary aims include an evaluation of a composite score of vaginal symptoms, sexual function, treatment satisfaction, menopause quality of life, and objective measures of genitourinary atrophy. We will also create a biorepository of vaginal and blood specimens. In a subset of women, we will examine whether treatment response is related to: a) the post-menopausal vaginal microbiome; b) vaginal mucosal inflammation; and c) reproductive hormone profiles. The in-depth focus on the mechanisms associated with postmenopausal vaginal symptoms will use state of the art microbiologic techniques on longitudinally collected biologic specimens and will guide future translational studies.

GroupInterventionDescription
PlaceboPlacebo gelOne hundred participants will be randomized into the 'placebo' arm of the study. This arm is comprised of two placebo preparations; placebo tablet and placebo gel applied on the same schedule as 'active' arms. The placebo tablet coating and excipient ingredients will be the same as are used for Vagifem®; the coating is made of hypromellose and polyethylene glycol and the excipient (inactive) ingredients are hypromellose, lactose monohydrate, maize starch, and magnesium stearate. Placebo gel. The product is an inert hydroxyethylcellulose gel (pH adjusted).
VagifemPlacebo gelOne hundred participants will be randomized into the Vagifem® 'active' arm. These women will receive a bottle of Vagifem® tablets (estradiol 10 mcg). One tablet is to be inserted vaginally daily for 2 weeks, then 2 days/week for the remaining 10 weeks of the study. Vagifem® tablets contain 10.3 mcg of estradiol hemihydrate equivalent to 10 mcg of estradiol. The excipient (inactive) ingredients are hypromellose, lactose monohydrate, maize starch, and magnesium stearate. Vagifem® comes as a small white film-coated tablet. The coating is made of hypromellose and polyethylene glycol. A placebo gel visually similar to Replens composed of inert hydroxyethylcellulose gel (pH adjusted) applied every 3 days over entire 12 weeks.
ReplensReplensOne hundred participants will be randomized into the Replens® 'active' arm. These women will receive a tube containing Replens® vaginal gel, with 2.5 gm applied vaginally every 3 days over 12 weeks. Replens® is a bioadhesive polycarbophil-based moisturizing vaginal gel containing; purified water (vehicle humectant), glycerin (moisturizer), mineral oil (as a moisturizer), polycarbophil and carbomer homopolymer type B (allow the product to stick to the vaginal wall), hydrogenated palm oil glyceride (moisturizer), sorbic acid (preservative, antimicrobial), methylparaben, sodium hydroxide (adjusts pH of product so it is suitable for vaginal use). A placebo tablet visually identical to Vagifem® is inserted daily for 2 weeks, then 2 days/week for remaining 10 weeks.

Primary Outcome Measures
NameTimeMethod
Most Bothersome Symptom (MBS) SeverityBaseline, Week 4, Week 12

Mean change from baseline to 12 weeks in the severity of the MBS on a scale of 0-3, better to worse.

Secondary Outcome Measures
NameTimeMethod
pHWeek 12

Objective measures of genitourinary atrophy: pH (\<5 or \>5) at week 12

Vaginal Symptoms IndexBaseline, Week 4, Week 12

The VSI is a Modified Bachman scale measuring vulvovaginal itching, dryness, irritation, soreness, and pain with sexual activity among sexually active women, each rated 0=none to 3=severe, and then averaged for a total score of 0-3.

Treatment SatisfactionWeek 12

Likert Scale 0 = no to 10 = complete satisfaction.

Patient Benefit Evaluation: Overall, do you believe that you experienced a meaningful benefit from the study medication? (Yes/No).

Vaginal Maturation IndexWeek 12
