Brief Summary:
The study was designed to evaluate the efficacy and safety of TX-12-004-HR 10 μg in treating moderate to severe symptoms of vaginal atrophy associated with menopause after 14 days of treatment, and to estimate the effect size and variability of vulvovaginal atrophy endpoints. In addition, the systemic exposure to estradiol from single and multiple doses of TX-12-004-HR was to be investigated.

Condition or disease Intervention/treatment Phase
Menopause Vulvovaginal Atrophy Painful Intercourse Dyspareunia Drug: Estradiol Drug: placebo Phase 2

Detailed Description:

This study was a randomized, double-blind, placebo-controlled trial to evaluate safety and efficacy of the TX-12-004-HR formulation in reducing moderate to severe symptoms of vaginal atrophy associated with menopause and to investigate the systemic exposure to estradiol following once daily intravaginal administrations of TX-12-004-HR for 14 days.

Postmenopausal subjects who met the study entry criteria were randomized to one of two treatment groups (TX-12-004-HR or Placebo). During the Screening period subjects were asked to self-assess the symptoms of vulvar and/or vaginal atrophy, including vaginal dryness, vaginal and/or vulvar irritation/itching, dysuria, vaginal pain associated with sexual activity and vaginal bleeding associated with sexual activity. Subjects with at least one self-assessed moderate to severe symptom of vulvar and/or vaginal atrophy identified by the subject as being most bothersome to her were eligible to participate in the study.

Primary Outcome Measures :
  1. Analysis of Change From Baseline to Day 15 in Maturation Index of the Vaginal Cell Type (Parabasal Cells) [ Time Frame: Baseline to 15 days post-treatment ]
  2. Analysis of Change From Baseline to Day 15 in Maturation Index of the Vaginal Cell Type (Superficial Cells) [ Time Frame: Baseline to 15 days post-treatment ]
  3. Analysis of Change From Baseline to Day 15 in Maturation Index of the Vaginal Cell Type (Intermediate Cells) [ Time Frame: Baseline to 15 days post-treatment ]
  4. Analysis of Change From Baseline to Day 15 in Vaginal pH [ Time Frame: Baseline to 15 days post-treatment ]
  5. Analysis of Change From Baseline to Day 15 in Severity of the Most Bothersome Vulvar and Vaginal Atrophy (VVA) Symptom [ Time Frame: Baseline to 15 days post-treatment ]
    The severity of the most bothersome VVA symptom was self-assessed by each subject using a VVA questionnaire. The questionnaire has a 4-point scoring scale with: None=0, Mild=1, Moderate=2, and Severe=3. The lower the score, the least bothersome it is to the subject.

  6. Analysis of Change From Baseline to Day 15 in Vaginal Bleeding Associated With Sexual Activity [ Time Frame: Baseline to 15 days post-treatment ]
    Total number (N=10) of participants analyzed within each treatment group who were sexually active at both Baseline and Day 15 and provided a response at both visits.

  7. Analysis of Change From Baseline to Day 15 in Investigator Assessment of the Vaginal Mucosa (Assessment of Vaginal Color) [ Time Frame: Baseline to 15 days post-treatment ]
    Outcome was measured by using a severity scale. No Atrophy is pink in color (0). Mild atrophy is lighter in color (1). Moderate atrophy is pale in color (2). Severe atrophy is transparent, either no color or inflamed (3).

  8. Analysis of Change From Baseline to Day 15 in Investigator Assessment of the Vaginal Mucosa (Assessment of Vaginal Epithelial Integrity) [ Time Frame: Baseline to 15 days post-treatment ]
    Outcome was measured by using a severity scale. No Atrophy=normal(0). Mild atrophy=vaginal surface bleeds with scraping(1). Moderate atrophy=vaginal surface bleeds with light contact(2). Severe atrophy=vaginal surface has petechiae before contact and bleeds with light contact(3).

  9. Change From Baseline to Day 15 in Investigator Assessment of the Vaginal Mucosa (Assessment of Vaginal Epithelial Surface Thickness) [ Time Frame: Baseline to 15 days post-treatment ]
    Outcome was measured by using a severity scale. No Atrophy has rogation and elasticity of vault(0). Mild atrophy has poor rogation with some elasticity noted of vaginal vault(1). Moderate atrophy is smooth, some elasticity of vaginal vault(2). Severe atrophy is smooth, no elasticity, constriction of the upper one third of vagina or loss of vaginal tone (cystocele and rectocele)(3).

  10. Analysis of Change From Baseline to Day 15 in Investigator Assessment of the Vaginal Mucosa (Assessment of Vaginal Secretions) [ Time Frame: Baseline to 15 days post-treatment ]
    Outcome was measured by using a severity scale. No Atrophy has normal clear secretions noted on vaginal walls(0). Mild atrophy has superficial coating of secretions, difficulty with speculum insertion(1). Moderate atrophy is scant not covering the entire vaginal vault, may need lubrication with speculum insertion to prevent pain(2). Severe atrophy has none, inflamed, ulceration noted, need lubrication with speculum insertion to prevent pain(3).

Ages Eligible for Study:   40 Years to 75 Years   (Adult, Older Adult)
Sexes Eligible for Study:   Female

Inclusion Criteria:

  1. Be a female between 40 and 75 years (at the time of randomization) who is willing to participate in the study, as documented by signing the informed consent form.
  2. Be a postmenopausal woman. Postmenopausal is defined with at least 12 months of spontaneous amenorrhea or 12 months post bilateral oophorectomy, with or without hysterectomy (documented by an operative report or patient reported). Women ≥ 60 years of age who have had a hysterectomy without bilateral oophorectomy prior to natural menopause are considered menopausal.
  3. Have a baseline evaluation requirements:

    • ≤5% superficial cells on vaginal smear cytology
    • Vaginal pH > 5.0
    • Estradiol level ≤ 50 pg/ml
    • At least one self-assessed moderate to severe symptom of vulvar and/or vaginal atrophy from the following list that is identified by the subject as being most bothersome to her:

      • Vaginal dryness
      • Vaginal pain associated with sexual activity
      • Vaginal and/or vulvar irritation/itching
      • Dysuria
      • Vaginal bleeding associated with sexual activity (absence vs. presence)
  4. Have a Body Mass Index (BMI) less than or equal to 34 kg/m2. (BMI values should be rounded to the nearest integer [e.g., 34.4 rounds down to 34, while 26.5 rounds up to 27]).
  5. Be willing to abstain from using products (other than study medication) that contain estrogen throughout study participation.
  6. Be judged by the Principal Investigator or Sub-investigator as being in otherwise generally good health based on a pre-study medical evaluation performed within 28 days prior to the initial dose of study medication. The medical evaluation findings must include:

    • a normal or non-clinically significant physical examination, including vital signs (sitting blood pressure, heart rate, respiratory rate and temperature).
    • a normal or non-clinically significant pelvic examination.
    • a mammogram that shows no sign of significant disease (can be performed within previous 9 months prior to initial dose of study medication). An acceptable mammogram is defined as a mammogram in which no masses or other findings are identified that is suspicious of malignancy. The site must obtain a copy of the official report for the subject's study file, and it must be verified that the mammogram itself is available if needed for additional assessment.
    • a normal or non-clinically significant clinical breast examination. An acceptable breast examination is defined as no masses or other findings identified that are suspicious of malignancy.
