Official Title: Continuous monitoring and management of vaginal health via multifunctional OCT/OCTA/OCE endoscopy, a randomized controlled trial

A Study On:

Genital Bladder - Genitourinary

Womens Health Obstetric/Gynecology

Study Description

The vaginal Optical Coherence tomography/angiography endoscopy imaging system. This technology is able to obtain a comprehensive image of the vaginal epithelium, blood vessels, and lamina propria. The primary focus of this study is establishing the Optical Coherence Tomography system's capability of capturing vaginal changes that occur before and after menopause, as well as before and after treatment with fractional-CO2 laser therapy.

There are two aims of this study.

Aim 1: To determine the feasibility and sensitivity of the integrated optical coherence endoscope to assess vaginal tissue integrity in pre, peri and postmenopausal women

We will enroll up to 90 women (age: 18 and older) who will be classified as pre-menopausal, peri- menopausal, or post-menopausal. There will be 30 women in each group. All enrolled subjects will first complete informed consents.

They will then fill out a questionnaire (the vulvovaginal symptom questionnaire) about their vaginal health. This will be followed by a pelvic exam to determine the vaginal health (vaginal health index) and to obtain a vaginal swab for assessment of the vaginal microbiome .

This will be followed by OCT scan of the vaginal tissue. There will be only one visit.

Aim 2: To optically visualize the effects of fractional-CO2 laser treatment on vaginal tissue over the course of C02 vaginal laser therapy.

Up to thirty Post-menopausal subjects with GSM who desire fractional-CO2 laser therapy, will be recruited.

Each visit will include: completion of a questionnaire (the vulvovaginal symptom questionnaire) about their vaginal health; followed by a pelvic exam to determine the vaginal health (vaginal health index) and to obtain a vaginal swab for assessment of the vaginal microbiome and an OCT scan of the vaginal tissue before the CO2 vaginal laser treatment.

This group will have a total of three visits with CO2 laser treatments. There will be a fourth visit which will include all the above study procedures except the CO2 laser treatment.

Subjects who complete 3 laser treatments will be offered participation in long term follow up with repeat OCT imaging every 3 months at 3, 6, 9 and 12 months after the final laser treatment to study the long- term effects of the laser treatment on the vaginal tissue.

Please read the information below and ask questions about anything that you do not understand. A
researcher listed above will be available to answer your questions.

You are being asked to participate in a clinical research potential participant database to identify
potential clinical research studies you may be eligible for. Participation in this database is voluntary.
You may choose to skip any question. You may refuse to participate or discontinue your involvement
at any time without penalty or loss of benefits. You are free to withdraw from this database at any
time. If you decide to withdraw from this database you should notify the research team
immediately.

You are eligible to participate in this study if you may be interested in participating in a research trial at UCI Health

We would like to interview you to learn more about your eligibility for current clinical research studies at UCI. The interview will last about 5-30 minutes, depending on the extent of your medical history.

Possible risks/discomforts associated with the database are hearing about potential clinical research studies that may not be of interest to you, invasion of your privacy, or a potential breach of confidentiality.

There are no direct benefits from participation in the database. However, this database may help inform you on clinical research studies that you may be eligible for. Participation in UCI clinical research studies help us gain important data and knowledge that may lead to improved treatment options for people with similar conditions to you in the future.

There are no alternative procedures available. The only alternative is not to participate in this study.

There is no compensation for your participation in this database.

There is no cost to you for participation in this database.

All information collected will be stored confidentially in a world-class securely-hosted application, “RealTime CTMS,” with robust data protections and encryption. This application has HIPAA compliant architecture and application rules to ensure data privacy and regulatory compliance.

Researchers will use your information to assess your eligibility for current and future clinical research studies at UCI. You may opt out at any time.

The research team, authorized UCI personnel, and regulatory entities, may have access to your study records to protect your safety and welfare.

While the research team will make every effort to keep your personal information confidential, it is possible that an unauthorized person might see it. We cannot guarantee total privacy.

Future Research Use
Researchers will use your information to conduct this study. Once the study is done using your information, we may share them with other researchers so they can use them for other studies in the future. We will not share your name or any other private identifiable information that would let the researchers know who you are. We will not ask you for additional permission to share this de-identified information

Data Retention - In accordance with UC Office of the President policy, information will be retained for 10 years after the end of the calendar year in which the research is completed.

If, during the course of this study, significant new information becomes available that may relate to your willingness to continue to participate, this information will be provided to you by the research team listed at the top of the form.
