Treating Postmenopausal Dyspareunia Where it Hurts

May 18, 2023 updated by: Jeffrey Jensen, Oregon Health and Science University

Treating Where it Hurts: A Randomized Blinded Clinical Trial of Local Estrogen to the Vulvar Vestibule for Dyspareunia in Postmenopausal Women

The purpose of this study is to compare the effectiveness of two low doses of estrogen cream applied to a new location for the treatment of moderate or severe pain during sexual intercourse in postmenopausal women.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Estrogen cream is FDA-approved for vaginal use for the treatment of sexual pain, but its use in a new location is experimental. Pain with sex is a common problem experienced by women after menopause and the relationship of pain to sexual difficulties is well established. The cause has been assumed to be atrophy and the location has been assumed to be the vagina. Recent focused studies have shown that the location of pain is the vulvar vestibule and usually not the vagina. This study will look at pain before and after therapy with estrogen when only the vulvar entryway area is treated. This will be a study focused on sexual dysfunction in postmenopausal women.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. Postmenopausal women aged 40 to 70 years old.

  2. Postmenopausal, demonstrated by at least one of the following:

    i. Cessation of menses for ≥1 years if age is >50 ii. Bilateral oophorectomy iii. A history of climacteric symptoms if below age 50, having an ovary and scarred or absent uterus.

  3. Onset of dyspareunia after menopause.*
  4. Stable heterosexual partnership ≥2 years (or by investigator discretion if less than 2 years) and both partners want to have more satisfying penetrative intimacy.
  5. No estrogen product use, local or systemic, for 6 months.*
  6. More than 6 months of consistent insertional pain with intercourse (may have stopped having intercourse due to this consistent experience of pain).*
  7. Willingness to enter a study where she will receive low-dose local estrogen.*
  8. Willingness to enter a study that requires application of cream on a frequent schedule for 3 months. *

  9. Willingness to evaluate the progress of therapies by use of the Tampon Test as many as 2 times per week, and willingness to attempt intercourse if the Tampon Test indicates tolerable penetrative pain.*

    • n/a for reference group

Exclusion Criteria:

  1. Consistently has pain in the pelvis or low abdomen during or after intercourse (deep dyspareunia).
  2. Negative cotton-swab touch test in the vulvar vestibule or vestibular tenderness that is not extinguishable by application of lidocaine 4% topical solution applied for 3 minutes.
  3. Partner with sexual dysfunction limiting his performance or making it inconsistent. (The use of male therapy for erectile dysfunction is acceptable.)
  4. Diagnosis by a physical therapist or clinician of significant pelvic floor muscle tension causing pain (pelvic floor myalgia) or has been found on screening examination to have pelvic floor tenderness or bladder tenderness.
  5. Constant burning pain localized to the vulva.
  6. Allergy to local estrogen products or lidocaine numbing agents.
  7. Previous estrogen receptor positive breast cancer or endometrial cancer.
  8. Endometrial thickness ≥5mm on screening via transvaginal ultrasound.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Median Dyspareunia Pain Scores After 4 Weeks Using Study Drug
Time Frame: Baseline to 4 weeks
Change in median dyspareunia pain scores between baseline and 4 weeks of use of nightly use of study medication. Pain will be assessed using 11-point Numerical Rating Scale (NRS) where 0 = no pain and 10 = worst possible pain.
Baseline to 4 weeks
Change in Median Pain Scores for Intercourse After 12 Weeks Using Study Drug
Time Frame: Baseline and 12 weeks
Difference in median dyspareunia pain scores between arms for intercourse at 12 weeks after use of nightly study medication for 90d. Pain will be assessed using 11-point Numerical Rating Scale (NRS) where 0 = no pain and 10 = worst possible pain.
