Trial Outcomes & Findings for Study to Determine Efficacy & Safety of a Low Concentration Estriol (0.005%) in Postmenopausal Vaginal Atrophy. (NCT NCT04574999)

NCT ID: NCT04574999

Last Updated: 2020-12-11

Results Overview

Maturation value (MV) is a cytologic parameter indicative of the degree of atrophy of the vaginal mucosa. This variable is a quantitative parameter indicative of the cytological status of the vaginal epithelium. The number of parabasal, intermediate and superficial cells was calculated from 300 consecutive cells of the samples of vaginal cytology, and the percentages of each type of cells obtained. The Maturation Value was obtained based on the following formula: 0.2 x (% parabasal) + 0.6 x (% intermediate) + 1.0 x (% superficial). The higher the value, the higher the maturation degree.

PRIMARY outcome

Population: Intention-to-treat population (ITT): all randomized women that received at least one dose of the study drug (Estriol gel vaginal 0.005% or placebo) after the randomization.

SECONDARY outcome

Timeframe: At week 12 /early withdrawal

Population: Intention-to-treat population (ITT): all randomized women that received at least one dose of the study drug (Estriol gel vaginal 0.005% or placebo) after the randomization.

As a consequence of reduced estrogen levels, the vaginal mucosa occurs loses its rugosity, its thickness decreases, and it becomes pale and friable. The production of glycogen decreases, which determines vaginal pH alkalinization.

Signs and symptoms of vaginal atrophy are: vaginal dryness, pruritus or itching, burning, dyspareunia, dysuria. For each of these symptoms the subject indicates one the following status: present, absent, missing. Symptoms of vaginal atrophy were scored by the patients in a numeric scale from 0 to 3, as shown below: 0 Absence. The symptom is not present 1. The symptom is of mild intensity, without interfering in the patient's activity 2. The symptom is of moderate intensity, causing obvious discomfort to the patient's 3. The symptom is very irritating and severe in intensity Signs of vaginal atrophy were evaluated by the investigator and scored on a numerical scale as shown below: 0 Absence. The symptom is not present 1. The sign is present and is considered a mild alteration 2. The sign is present and is considered a moderate alteration 3.
