Clinical Trial Summary

A randomized controlled trial looking at the effects of vaginal estrogen and a nonhormonal alternative on the vaginal and urinary microbiome in women with genitourinary syndrome of menopause.


Description:

This is a study is looking at the effects of vaginal estrogen and a nonhormonal alternative on the vaginal and urinary microbiome in women with genitourinary syndrome of menopause. The primary objective is to describe the bacterial communities associated in the vagina and urine of postmenopausal women receiving treatment for genitourinary syndrome of menopause with conjugated equine estrogen topical cream (Premarin®) and a nonhormonal alternative (apricot kernel oil). The participants will be randomized to either conjugated equine estrogen topical vaginal cream or apricot kernel oil. They will be given validated questionnaires to assess their urinary and vaginal symptoms, sexual function, quality of life, and impressions of severity and improvement.

Outcome

Type Measure Description Time frame Safety issue
Primary Vaginal and urinary predominance of anaerobic/fastidious taxonomy of micro-organisms on genomic, microbial DNA analysis of vaginal and urinary specimens. Predominance (greater than 50%) in vaginal and urinary specimen of anaerobic and/or fastidious organisms in the study population compared between conjugated equine estrogen cream (Premarin) and apricot kernel oil. The primary analysis will compare the prevalence of genomic taxonomic anaerobic and/or fastidious organism predominance (>50%) between the estrogen group and the non-estrogen alternative group. 3 months
Secondary Change in vaginal symptom questionnaire (VSQ) Change in vaginal symptoms as assessed by vulvovaginal symptom questionnaire (VSQ) at baseline and after treatment. 3 months
Secondary Vaginal and urinary predominance of anaerobic/fastidious taxonomy of micro-organisms on genomic, microbial DNA analysis of vaginal and urinary specimens. Predominance (greater than 50%) in vaginal and urinary specimen of anaerobic and/or fastidious organisms in the study population compared between the conjugated equine estrogen cream (Premarin) and apricot kernel oil. The primary analysis will compare the prevalence of genomic taxonomic anaerobic and/or fastidious organism predominance (>50%) between the baseline patients and the patients at 3 months and compare the change in prevalence in this taxonomic predominance between the two study groups. 3 months
