Detailed Description
This is a prospective, international, multicenter study performed in 2 steps:
- From 0 to 12 weeks: randomized, single-blind, placebo-controlled study;
- From 12 to 52 weeks: open label, treatment only study.
The study will assess the efficacy of DESIRIAL® in reducing the vulvovaginal symptomatology after a single injection. One hundred twenty one postmenopausal women of minimum age 45, with symptoms associated with vulvovaginal atrophy, refusing estrogen therapies for treatment of symptoms or with contraindications for such therapies, with at least one moderate to severe vulvovaginal symptom among dryness sensation, dyspareunia, itching / irritation and pain, who have given her informed consent and met all the eligibility criteria, will be enrolled. Patients will randomly (2:1 ratio) receive a 1mL-injection of DESIRIAL® (Desirial Only group, DO) or placebo (Placebo and Desirial group, PAD) in the vestibular and vaginal mucosa using the multi-puncture and/or retrolinear technique at D0. If still eligible 12 weeks after, patients from PAD group receiving placebo at Day 0 will be treated with DESIRIAL®. Group DO will be followed up at 4, 12, 24, 36 and 52 weeks timepoints.Group PAD will be followed up at 4, 12, 16, 24, 36 and 48 weeks timepoints. Phone interview will be performed between 3 and 5 days after injection to check safety. Variation of vulvovaginal symptomatology, sexual function and vaginal pH will be measured using vulvovaginal symptomatology questionnaire, Female Sexual Function Index (FSFI) and vaginal pH indicator strip respectively. Safety will also be assessed through collection of adverse events.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Variation of most bothersome symptom
Time Frame: 12 weeks after Day 0
|
Changes in mean Most Bothersome Symptom (MBS) severity score from baseline (Visit 1) to 12 weeks after a single injection of DESIRIAL® in comparison to a placebo (DO group versus PAD group). Symptom intensity is assessed using a 4-score scale (from 0 to 3) with minimum score representing a better outcome. Score 0 corresponds to "None", score 1 to "Mild", score 2 to "Moderate" and score 3 to "Severe". |

FSFI consists in 19 questions with multiple-choice responses coded from 0.0 to 5.0. Each score has a specific meaning depending on the question. The scale has six sexual domains. The maximum score for each domain is 6.0, obtained by summing item responses and multiplying by a correction factor. The total composite sexual function score is a sum of domain scores and ranges from 2.0 (not sexually active and no desire) to 36.0. |
