Conditions: Vaginal Atrophy
Keywords: Postmenopausal women
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 167
Healthy volunteers: no

Brief summary:
Randomized, double-blind, placebo-controlled multicentre study, with parallel groups, to determine the efficacy and safety of a new low-concentration estriol formulation (ITFE-2026 0.005%) for application by vaginal route in the treatment of postmenopausal vaginal atrophy.

Primary objective:

• To evaluate the efficacy of 0.005% Estriol vaginal gel by evaluation of the change in the maturation value of the vaginal epithelium (MV) after 12 weeks of treatment.

Secondary objectives:

* To determine the variation of the vaginal pH, as well as symptoms and signs suggestive of vaginal atrophy after 12 weeks of treatment.
* To study the variation of the MV, pH and symptoms and signs suggestive of vaginal atrophy after an initial observation period of 3 weeks.
* To evaluate the safety of 0.005% Estriol vaginal gel
* To evaluate the acceptability of 0.005% Estriol vaginal gel

Detailed description:
This is a randomized, double-blind, placebo-controlled multicentre study, with parallel groups, to determine the efficacy and safety of a new low-concentration estriol formulation (ITFE-2026 0.005%) for application by vaginal route in the treatment of postmenopausal vaginal atrophy.

Eligible patients were randomised in a ratio of 2:1 to 0.005% Estriol vaginal gel : placebo. Each patient was treated for 12 weeks followed by a one-month observational period. The patients attended the study centre at baseline and at 3, 8 and 12 weeks after start of treatment. Vaginal cytology was performed at baseline and at weeks 3 and 12; the vaginal pH and the signs and symptoms of vaginal atrophy were recorded at baseline and after 3 and 12 weeks of treatment. Vital signs, gynaecological exploration and changes in health and concomitant medication were documented at each visit. Transvaginal ultrasound was performed at screening and week 12. The investigators telephoned the patient approximately one month after the final visit to check if the patient had experienced any adverse events since the final visit. Two independent cytopathologists assessed the maturation value of each cytology sample at the end of the study.
