Non-hormonal alternatives for the treatment of genitourinary syndrome of menopause (GSM) are needed. In this proposed trial, patients who are diagnosed with GSM will be randomized to receive either a hyaluronic acid (HLA) vaginal insert or vaginal estrogen topical cream for 12 weeks. There will be a baseline visit and an 12 week follow up visit, at which points the patient will undergo a detailed history and physical examination including a pelvic exam, vaginal pH sampling, vaginal cell sample for microscopic analysis, and will fill out a vulvovaginal symptom questionnaire (VSQ). These study arms will be analyzed to assess the efficacy of HLA as compared to the gold standard of vaginal estrogen to treat GSM symptoms.

Device Revaree

Hyaluronic Acid Vaginal Insert (Revaree). A 2g vaginal insert that contains 5mg of HLA sodium salt and a base of semi-synthetic glycerides. It is an insert that does not require an applicator and should be placed in the vagina while laying down twice weekly.

  • Other names: HLA Vaginal Insert

Drug Estrace

Vaginal estrogen cream, estradiol: 100mcg

  • Other names: Vaginal estrogen cream

Change in VSQ Score

The VSQ (Vulvovaginal Symptoms Questionnaire) is a 21-question survey developed in 2012 that specifically asks about GSM symptoms, their emotional impact, sexual impact, and life impact. Each question is scored from 0 (free of discomfort) to 3 (severe discomfort) The total score ranges from 0 (symptom-free in all areas) to 63 (severe discomfort in all areas) - the higher the score, the more severe the discomfort.

Investigational

-3.3
score on a scale (Mean)
95% Confidence Interval: -5.5 to -1.1

Standard of Care

-3.7
score on a scale (Mean)
95% Confidence Interval: -6.0 to -1.3

Change in VMI

VMI (Vaginal Maturation Index) is the microscopic analysis of vaginal tissue that assigns the percentage to the amount of squamous cells visualized. Only the % of squamous cells will be reported in this study since that is most closely correlated with hormonal influence on the vaginal tissue. Vaginal tissue sample will be obtained via scraping for VMI.

Investigational

Percentage of squamous cells (Mean)
95% Confidence Interval: -2.7 to 11.5

Percentage of squamous cells (Mean)
95% Confidence Interval: 27.6 to 49.2

Change in Vaginal pH

Pelvic samples will be collected to test vaginal pH.

Investigational

95% Confidence Interval: -0.3 to -0.1

Change in VAS Score - Dyspareunia

VAS (Visual Analog Scale) score will be reported for dyspareunia. VAS is a visual scale attempting to capture the intensity of a symptom. For each symptom, the score ranges from 0-10. The higher the score, the more severe the symptom. Each symptom will be reported separately.

Investigational
