Vaginal Estradiol vs Moisturizer to Improve Postmenopausal Vaginal Aging Symptoms and the Microbiome in Women Living With HIV

A Phase 4 interventional study of Vaginal estradiol tablets and Vaginal moisturizer in Menopausal Complaints, Vaginal Atrophy and Genitourinary Symptoms, sponsored by Albert Einstein College of Medicine. Not yet recruiting at 1 site in United States. Open to female participants aged 40 Years to 70 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-07-28.

Primary conditionVaginitisRegistry: Acquired Immunodeficiency SyndromeReclassifiedWhy we changed it
Registry
Acquired Immunodeficiency Syndrome — the first condition term the registry derived for this study.
ClinicalTrials.gg
Vaginitis
Why
  1. The registry often attaches Acquired Immunodeficiency Syndrome to studies about something else, and this study's title and listed conditions do not name it.
  2. The study's listed conditions name Vaginitis.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

This is a research study about the effects of vaginal estradiol compared to moisturizer on vaginal symptoms of menopause and the microbiome in women with HIV. This research study aims to understand how vaginal products affect the aging of the female genital tract in women living with HIV who are menopausal or perimenopausal and have vaginal or urinary symptoms. There is a comparison group of women who are living without HIV. Participants with HIV and vaginal or urinary menopausal symptoms (e.g., dryness, irritation, soreness, itching, pain with sex, dysuria, urgency, or frequent urinary tract infections) will be asked to apply vaginal estradiol or a vaginal moisturizer (Replens). Participants who have vaginal or urinary menopausal symptoms and do not have HIV will receive vaginal estradiol.

In context

Vaginitis Reclassified

98 studies on the registry are indexed under Vaginitis; 12 are open to participants now.

This study's planned enrollment of 62 is below the median of 108 across 71 interventional studies indexed under Vaginitis.

Lead sponsor

Albert Einstein College of Medicine is the lead sponsor of 201 studies on the registry; 21 are open to participants now.

Of its 46 completed or terminated interventional studies of FDA-regulated products, 37 (80%) have results posted.

Compared within Vaginitis, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Acquired Immunodeficiency Syndrome. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • female
  • at least 40 years old
  • menopausal (no menses in 12 months) within 2 years of last menstrual period or perimenopausal in the late menopausal transition, defined as an interval of amenorrhea greater than or equal to 60 days
  • have symptoms of the genitourinary syndrome of menopause (GSM) which developed within the prior 2 years. Symptoms of GSM include vaginal symptoms including dryness, soreness, itching, irritation and dyspareunia and/or urinary symptoms including urgency, frequency and recurrent urinary tract infections (UTIs)

Exclusion criteria

Exclusion Criteria:

  • Unexplained or unevaluated abnormal genital bleeding
  • Current or suspected pregnancy
  • Desired pregnancy
  • If less than 55 years old, have had a hysterectomy and have at least one ovary (as menopause cannot be determined in this case by amenorrhea alone)
  • Pelvic or vaginal surgery in the prior 60 days
  • Used systemic reproductive hormones in the last 2 months
  • Used antibiotics in the last 30 days
  • Used medications in the prior 60 days including biologics, chemotherapeutics or post transplant immunosuppressive medications
  • Used any vaginal or vulvar preparations in the last month
  • Current active vaginal infection diagnosed at study entry
  • Any serious disease or condition that may interfere with study compliance
  • Current or previous history of breast cancer or estrogen dependent cancer (e.g., ovarian, endometrial)
  • Current or previous history of deep vein thrombosis or pulmonary embolism
  • Current or previous history of myocardial infarction or stroke
  • Known clotting disorder including Protein C, Protein S and antithrombin deficiency, Factor V Leiden or prothrombin mutations
  • Known severe liver disease including cirrhosis or active
  • Known allergic reaction to Vagifem (estradiol vaginal tablet) or Replens
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Study arms

  • Experimental
    Vaginal Estradiol, Participants Living With HIV

    Participants living with HIV randomized to this arm will use vaginal estradiol tablets for the duration of the study (16 weeks)

    Drug: Vaginal estradiol tablets

  • Active comparator
    Vaginal Estradiol, Participants without HIV

    Participants without HIV enrolled in the study will use vaginal estradiol tablets for the duration of the study (16 weeks). A control group of women without HIV with GSM (n=12) will be treated with vaginal estradiol for 16 weeks but will not be randomized to moisturizer as topical estrogen has already been shown (and is FDA approved) to improve symptoms and the vaginal microbiome in women without HIV infection.

    Drug: Vaginal estradiol tablets

  • Active comparator
    Vaginal Moisturizer, Participants Living with HIV

    Participants living with HIV randomized to this group will use vaginal moisturizer for the duration of the study (16 weeks)

    Other: Vaginal moisturizer

Interventions

  • Using a pre-loaded single-use plastic applicator, participants will insert one 10 microgram estradiol tablet intravaginally daily for 2 weeks and then one tablet twice weekly for the remainder of the study for a total of 16 weeks.

    Also known as: Vagifem

  • OtherVaginal moisturizer

    Using a pre-loaded single-use plastic applicator, participants will insert one vaginal moisturizer applicator intravaginally twice weekly for the duration of the study for a total of 12 weeks.

    Also known as: Replens

What researchers measure

Primary outcomes

  1. Change in the vaginal microbiome (bacteria) as defined by the change in alpha diversity

    Changes in the vaginal microbiome as defined by the change in alpha diversity from baseline to 16 weeks will be assessed. It is hypothesized that this may be a biomarker for improvement in vaginal health. Lower alpha diversity would indicate a favorable change in the microbiome.

    Time frame: From Baseline to 16 weeks

Secondary outcomes

  1. Change in genitourinary syndrome of menopause (GSM) symptoms as defined by the composite GSM symptom index

    Using a survey administered at each visit, participants will rate the severity of five vaginal (dryness, itching, irritation, soreness, and dyspareunia) and three urinary (frequency, urgency, recurrent UTIs) symptoms based on a four-point scale (0=none, 1=mild, 2=moderate, 3=severe). A composite GSM symptom index will be calculated as the mean severity of the corresponding symptoms at each visit. A higher score indicates increased severity of symptoms. It is anticipated that both vaginal estradiol and the vaginal moisturizer will lead to improvement in the symptoms of the genitourinary syndrome of menopause.

    Time frame: From Baseline to 16 weeks
