About

Aim of the study: To assess the efficacy of MonaLisa Touch procedure for the management of genitourinary syndrome of menopause (GSM) in a randomized double-blind placebo controlled study.

Full description

Study design: Randomly assigning the intervention can eliminate the influence of unknown or immeasurable confounding variables that may otherwise lead to biased and incorrect estimate of treatment effect. Also, randomization eliminates confounding by baseline variables and blinding eliminates confounding by co-interventions, thus eliminating the possibility that the observed effects of intervention are due to differential use of other treatments. The best comparison is placebo control that allows participants, investigators and study staff to be blinded. The advantage of trial over an observational study is the ability to demonstrate causality.

Background: Genitourinary syndrome of Menopause is a condition of postmenopausal women due to estrogen deprivation which results in progressive worsening of the vaginal and vulvar anatomy with symptoms of vulvar itching or pain during intercourse, vaginal dryness, urinary urgency and frequency and frequent bladder infections. It could ultimately lead to vaginal bleeding, petechial hemorrhages, vaginal narrowing or stenosis and hypertonicity of the pelvic muscles due to anticipation of coital pain. The hypertonicity by itself can cause pelvic pressure or pain.

Thus, GSM is a chronic progressive disease state that if left untreated could have dire vaginal and urogynecological consequences.

MonaLisa Touch is a fractional CO2 laser that has been specially designed with the DEKA pulse to stimulate vaginal tissue. It is delivered in a very precise manner and results in the synthesis of collagen and stratification of the vaginal epithelium with improvement of the vaginal pH and moisturization of the vaginal tissue due to increased blood flow and turgidity of the ground substance from the synthesis of the proteoglycans, hyaluronic acid and collagen.

Initial trials on MonaLisa Touch have shown promising results with significant improvement in vaginal exams and patient satisfaction scores.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Triple Blind

---

34 participants in 2 patient groups

Control/sham

Sham Comparator group

Description:

The CO2 laser will not be activated but the same procedure of moving the probe inside the vagina in a systematic manner including depressing the foot pedal at similar frequency will be performed. The smoke evacuator will also be activated, laser eye glasses and masks worn by the laser team and the subject. However, the laser will remain in the standby mode.

Treatment:

Device: MonaLisa Touch

Treated

Active Comparator group

Description:

Active arm subjects will be treated intravaginally with the fractional microablative CO2 laser system (SmartXide 2 V 2 LR, MonaLisa Touch, DEKA, Florence, Italy), using the following setting: dot power 30 watt, dwell time 1000 μs, dot spacing 1000 μm and the smart stack parameter from 1 to 3. For the vulva, the dot power will be reduced to 26 watts, dwell time 800 μs, dot spacing 800 μm and the smart stack parameter of 1.
