Intravaginal Negative Pressure Medical Device for Treatment of Genitourinary Syndrome of Menopause (GSM)

There will be up to 6 in-person visits (screening visit, 4 treatment visits and 2 follow-up visits) for all subjects.

Screening After signing the informed consent form, subjects will be screened to ensure they meet the inclusion and exclusion criteria before initiating treatment.

Screening includes collecting information from the patient history (medical history, demographics and medications) as well as conducting the following clinical assessments:

• Dilator suitability.
• Papanicolaou Test (current within last year or repeated within 2 weeks of initial treatment).
• Sexually transmitted infections screening test (gonorrhea, chlamydia, bacterial vaginosis, trichomonas and yeast)
• Pregnancy Test
• Vaginal Health Index (VHI) Score.
• Vaginal pH.
• Clinical examination to confirm that the vaginal canal is free of any lesions other than symptoms of GSM.
• Self-assessment of symptoms related to GSM and confirmation of moderate to severe dyspareunia.

All screening information necessary to evaluate whether the subject meets the inclusion/exclusion criteria should be available and reviewed prior to treatment. Subjects who do not meet the eligibility criteria upon screening will be considered screening failures. Screening failures will not be followed further except in case of adverse events occurring at the screening visit. In this case, subjects will be monitored until the adverse event(s) are resolved.

The eligible subjects will be randomized and introduced to the treatment at the first treatment visit.

Treatment Visits

The following are completed prior to treatment:

• Pre-Treatment Assessments

• Urinary Tract Infection Test.
• Vaginal pH.
• Vaginal moisture (modified Schirmer Test).
• Vaginal Maturation Index (VMI) Score.
• Clinical Examination - Immediately prior to each treatment, a visual examination of the vulvo-vaginal area is carried out. The appearance of the vaginal mucosa before each treatment will be assessed (by the same investigator for each subject) taking parameters of Vaginal Mucosa Assessment (VMA) into account.
• Vaginal Health Index (VHI) Score.
• Imaging of Vaginal Wall - An image of the mucosa will be taken after the clinical examination and prior to each treatment.
• Self-assessment of symptoms related to GSM and confirmation of moderate to severe dyspareunia.
• Female Sexual Function Index (FSFI) questionnaire.
• Randomization

Before initiating treatment, subjects continuing to meet eligibility criteria will be randomized to one of following two arms:

• VITA AV Clinical System (active treatment).
• Sham device.

Each active treatment is delivered at a negative pressure of 460 mmHg for 5 minutes. After the treatment, the clinician will re-assess the vaginal mucosa to review the induced micro-trauma, if any. This appears as visible dome shaped effects on the vaginal mucosa corresponding to the apertures in the intravaginal tip. They may appear red indicating induced petechiae, which is the desired response. Images will be taken after each treatment to record the treatment effect at site # 2.

After the initial treatment, each subject returns for an additional 3 treatments performed at 4-week intervals (+/-4 days) for a total of four treatments.

In addition, the following are assessed, as part of the clinical examination, prior to performing subsequent treatments to ensure that the vaginal canal is free from:

• bleeding,
• inflammation,
• the desired microtrauma effects of any previous treatment.
• other abnormal effects.

Follow-Up Visits:

Will occur at 1-, 3- post the last treatment will take place for all subjects. Will occur at 6-, 9- and 12-months post the last treatment will take place for subjects in the Active treatment only.

Note: The 9-month follow-up visit will be conducted via phone call.

Inclusion criteria

• Healthy postmenopausal subjects from 1 to 15 years since their last menstrual cycle.
• Willingness to refrain from using alternative therapies for treatment of symptoms of GSM, unless medically necessary, through the duration of this study.
• Moderate to severe dyspareunia associated with GSM. (i.e., ≥4 on the 11-point patient-reported numeric rated dyspareunia scale).
• Subjects who are sexually active (i.e. have had or have attempted to have sexual activity with vaginal penetration within approximately 1 month of screening visit).
• Subjects who anticipate engaging or attempting to engage in sexual activity (with vaginal penetration) at least twice a month during the trial.
• Vaginal Health Index (VHI) score of less than or equal to 15.
• Vaginal pH >5.0.
• The subject is anatomically suitable to the intravaginal tip as determined by the Investigator.
• Normal Papanicolaou test within the past year (or should be done 2 weeks before the trial begins). Subject can ONLY participate on negative results.
• Vaginal canal free of any lesions other than symptoms of GSM as determined by the Investigator.
• Negative screening for chlamydia, gonorrhea, bacterial vaginosis, trichomonas and yeast.
• Willingness and ability to give voluntary written informed consent to participate in the study and comply with protocol requirements.
• Willingness to refrain from sexual intercourse for at least 48 hours before all visits and for at least 48 hours after all treatments.
• Willingness to stop using current vaginal lubricant, moisturizers or similar and only use the lubricant provided by the clinic.
• Willingness to stop using the clinic assigned lubricant for at least 48 hours before all scheduled visits post screening.
• Willingness to refrain from any pelvic floor therapy for the duration of the trial.
• Willingness to refrain from enrolling in another clinical trial for the duration of this study.

Exclusion criteria

• Subjects on Hormone Therapies (HT), systemic or local, or within 6 months of cessation of HT prior to inclusion in the study.
• Subjects with bleeding disorders.
• Subjects with any sexually transmitted disease.
• Subjects on prescribed anticoagulants such as antiplatelets and anticoagulants (Heparin, Warfarin, Clopidogrel, Apixaban, Rivaroxaban).
• Any active genital infections.
• Abnormal Papanicolaou test within the past year.
• Positive pregnancy test or planned pregnancy during the study period.
• Complete procidentia or prolapse that in investigator opinion would be unsuitable for probe placement.
• Subjects with urogenital sinus (this is when urethral opening is combined with the vagina opening), otherwise the urethral opening will be traumatized potentially resulting in a urinary tract infection (UTI).
• Subjects with a compromised immune system.
• Subjects who have undergone pelvic irradiation treatment.
• Subjects who have undergone off-label procedures such as "vaginal rejuvenation" (e.g., laser or thermoablative techniques).
• Pelvic surgery within 6 months prior to the start of the study.
• Undiagnosed vaginal bleeding.
• Subjects with bleeding during screening examination due to friable vaginal mucosa and/or very thin epithelial layer, such that investigator determines the VITA AV treatment would be contraindicated.
• Subjects receiving chemotherapy or radiotherapy or subjects with any diagnosed gynecological cancers.
• History of breast cancer who have had chemotherapy within the last 5 years or are on aromatase inhibitors.
• Any general health or anatomical conditions, mental health or social situation which, in the opinion of the investigator, could represent an increased risk for the subject, or the ability of the subject to complete study requirements.
• Currently participating or considering participation in any other research of an investigational drug or device. Does not include observational studies.
• Subjects that have previously received this treatment as part of a clinical trial.
