Outcome Measures

Primary Outcome Measures

  1. Responder [15 days]

    % Responders where a "Responder" is defined as a patient with: At least a 25% reduction from baseline in the sum of % basal/parabasal + % intermediate cells on vaginal cytology; and Vaginal pH < 5.0 with a change from baseline vaginal pH of at least 0.5

  2. Change in Most Bothersome Symptom [15 days]

    Mean change from baseline to Day 15 in dyspareunia score (the self-identified most bothersome symptom in women with VVA). On a scale of 0 to 3, where 0 = none, 1=mild, 2=moderate and 3 = severe

Secondary Outcome Measures

  1. Treatment Success in Most bothersome symptom [15 days]

    proportion of patients in each treatment group that are considered a Treatment Success at the end of the treatment period evaluated on Day 15. A "Treatment Success" is defined as a score of 0 or 1 on Day 15 for dyspareunia (the self-identified most bothersome symptom at baseline).On a scale of 0 to 3 where 0 = none, 1=mild, 2=moderate and 3 = severe

  5. At least 6 weeks postsurgical bilateral oophorectomy

  6. Have less than or equal to 5% superficial cells on vaginal cytological smear.

  7. Vaginal pH > 5.0.

  8. Moderate to severe symptom of vaginal pain associated with sexual activity considered the most bothersome vaginal symptom (dyspareunia) of VVA by the patient at screening visit. (i.e., a VVA Symptom Self-Assessment Questionnaire score of 2 or 3) (Appendix B).

  9. Women should be sexually active (for example, have sexual activity with vaginal penetration within approximately one month of screening visit).

  10. Women should anticipate having sexual activity (with vaginal penetration) during the conduct of the study, and agree to at least one episode of sexual intercourse within study days 10-13.

  11. Baseline systolic blood pressure should be no greater than 150 mm Hg and diastolic blood pressure no greater than 90 mm Hg.

  12. Normal mammogram completed within 9 months before enrollment and a normal clinical breast examination prior to enrollment in the study.

  13. Patients who have underwent complete Hysterectomy, or patients with an intact uterus (including patients who underwent a partial hysterectomy) must have:

  14. A documented papanicolaou (PAP) smear conducted within 12 months before Screening with no findings that the Investigator believes would contraindicate the use of topical vaginal estradiol.

  15. Documented vaginal ultrasonography results within 3 months before Screening to confirm an inactive endometrial lining, defined as endometrial thickness <4mm.

  16. In the opinion of the Investigator, the patient will comply with the protocol and has a high probability of completing the study.

Exclusion Criteria:
  1. Premenopasual, perimenopausal, pregnant or lactating patient or planning a pregnancy.

  2. Significant history or current evidence of chronic infectious disease, system disorder, organ disorder or other medical condition that in the Investigator's opinion would place the study patient at undue risk by participation or could jeopardize the integrity of the study evaluations.
