Brief summary
This is a four-arm, randomized, double-blind, parallel group, placebo-controlled study to compare the effects of two doses of DR-2041(Synthetic Conjugated Estrogens, A) Vaginal Cream on vulvovaginal atrophy in postmenopausal women with or without a hysterectomy and/or oophorectomy.
Detailed description
The study will include a screening period up to 4 weeks and a 12- week treatment period. The overall study duration for participants will be approximately 16 weeks. Study participants will undergo physical and gynecological exams, and blood tests for clinical laboratory assessments. All patients with a uterus will undergo transvaginal ultrasound.
Interventions
1 gram administered vaginally daily for the 1st 7 days then twice a week thereafter
2 grams administered vaginally daily for the 1st 7 days then twice a week thereafter
1 gram administered vaginally daily for the 1st 7 days then twice a week thereafter

Eligibility
Inclusion criteria
* Naturally or surgically menopausal * Moderate or severe symptoms of vaginal atrophy (ie, dryness, itching, pain, uncomfortable intercourse)
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean Change in the Symptom Identified by the Patient to be Most Bothersome | Baseline to Week 12 | Change= Week 12 score - Baseline Score. The most bothersome symptom was derived from the subject self-assessment of vaginal atrophy, which consisted of 5 questions concerning severity of symptoms graded on a scale of 0-3(none, mild, moderate or severe) or 7 for not applicable. |
| Mean Change in Vaginal pH | Baseline to Week 12 | Change= Week 12 vaginal pH - Baseline vaginal pH |
| Mean Change in Maturation Index | Baseline to Week 12 | Change= Week 12 maturation index -baseline maturation index. Matuation index was calculated using the following equation: Maturation Index = (% Parabasal cells \* 0) + (% Intermediate Cells \* 0.5) + (% Superficial Cells \* 1.0) |

Outcome results
Mean Change in Maturation Index
Change= Week 12 maturation index -baseline maturation index. Matuation index was calculated using the following equation: Maturation Index = (% Parabasal cells \* 0) + (% Intermediate Cells \* 0.5) + (% Superficial Cells \* 1.0)
Time frame: Baseline to Week 12
Population: Modifed Intent-to-Treat: All subjects who met study protocol requirements at baseline for all 3 primary efficacy inclusion criteria, who were randomized to treatment, received at least 1 dose of study drug, for whom there were a baseline assessment and at least 1 post-randomization assessment of VVA consisting of all 3 co-primary efficacy endpoints
