Phase 3

Not yet recruiting

• Conditions: Women With Breast Cancer
• Interventions: Drug: Prasterone (DHEA)

• Registration Number: NCT06611514
• Lead Sponsor: European Institute of Oncology

Brief Summary

The goal of this interventional study is to evaluate the effect of Intravaginal Prasterone for the treatment of moderate to severe symptoms of genitourinary syndrome (GSM) due to natural, surgical or treatment-induced menopause and the effect on the quality of life, including sexual function and mood well-being, in women with Breast Cancer. A sample size of 95 patients will be needed to show that the proportion of women showing symptom improvement is greater than 50%. Subjects will be followed up at four weeks and twelve weeks of treatment. One and three-month outcomes will be provided after the end of treatment. Comparison between menopausal women with previous breast cancer that have finished hormonal therapy or with ER negative breast cancer and women currently under endocrine therapy with AIs will be performed.

improvement in vaginal signs	6 months	To establish the improvement in vaginal signs using the Vaginal Health Index Scale (VHI)
evaluation fo maturation index	6 months	To assess the maturation index (as percentage of superficial, intermediate and parabasal cells) in the vaginal mucosa
