Study summary

A prospective, open, randomized and controlled clinical intervention study in women over 45 years of age with a diagnosis of vulvovaginal atrophy (dryness and / or dyspareunia, etc.) and vulvar and / or vestibular pain. The efficacy of Prasterone treatment is evaluated in those patients willing to undergo the treatment compared to the control group.

Read the detailed description

A sample of 50 women over 45 years of age with at least one year of amenorrhea and who require treatment for vulvovaginal atrophy of moderate and / or severe intensity and who present vulvar and vaginal pain within these symptoms will be chosen.

At the beginning of the study, after passing the selection criteria and signing the informed consent, the patients will be randomly assigned to one of the two arms of the study, (active group) or (control group), said assignment will be made randomly. Through a computer program where one or the other arm of treatment will be assigned to the patient at random to guarantee the homogeneity of both study groups and thus avoid selection biases.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
