Evaluate Efficacy and Safety of LACUDY for Improving Vaginal Environment in Breast Cancer Patient

December 6, 2022 updated by: Gun Oh Chong

A Randomized Prospective Clinical Trial to Evaluate Efficacy and Safety of LACUDY for Improving Vaginal Environment Among Breast Cancer Survivals Who Receive Anti-estrogen Therapy

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change of Vaginal health index
Time Frame: Prior to administration, 1 month after LacuD treatment(2 times in total)
Female Sexual Function Index (FSFI) Quality of life assessed by Breast Version 4 (FACT-B)
Prior to administration, 1 month after LacuD treatment(2 times in total)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Vaginal microbiome
Time Frame: Prior to administration, 1 month after LacuD treatment(2 times in total)
Take one cervicovaginal swab sample each
