• Conditions: Hormone Receptor-positive Breast Cancer
• Interventions: Drug: LACUDY

• Registration Number: NCT05651087
• Lead Sponsor: Gun Oh Chong

Brief Summary

Adjuvant hormone treatments for early breast cancer are associated with frequent bothersome side effects with major negative impact on patients' quality of life and treatment adherence. Patients most commonly report menopausal symptoms including vaginal dryness, vaginal bleeding, and dyspareunia. Even though previous studies have reported that estrogen topical agent relives these symptoms, non-hormonal therapy should be considered first due to concerns about the role of estrogen in breast cancer development. Therefore, this trial is planned to evaluate the efficacy and safety of LacuD (hyaluronic acid, lactic acid and alginate) in the vaginal environment of breast cancer patients receiving hormone therapy.

Detailed Description

* Registered subjects are 1:1 randomized using a random sequencing generator (www.random.org). Experimental group with 30 patients and Control group with 30 patinets.

* In the case of the experimental group, LACUDY 2mL is inserted twice a week for a month before going to bed for 4 weeks.

* Unpack the product and take it out.

* Remove the cap by turning it.

* Fit the nozzle to the end of the syringe and turn it to combine.

* Hold the syringe with the nozzle facing the vulva, insert it about 5-6 cm into the vagina, and then slowly press the tip of the push rod with patient's thumb to inject all the liquid in the syringe into the vagina.

* Slowly remove the syringe as the nozzle opens.

* It is recommended to wear a pad as the injected solution may flow out.

* In the case of the control group, they go about their daily lives without any treatment.

* Both the experimental group and the control group are instructed not to administer intravaginal suppositories or other drugs related to vaginal atrophy and sexual function improvement.

* A total of 2 questionnaires were conducted before and after treatment.
