Brief summary

This study seeks to address accessible management of endometriosis-associated chronic pelvic pain by evaluating a novel device used in the home. The study is designed as a proof-of-concept single-arm pilot study, and the primary objective is to assess change in overall self-reported pelvic pain in people with endometriosis-associated chronic pelvic pain following the use of the Hyivy intravaginal device.

Detailed description

Endometriosis is a chronic, inflammatory, estrogen-dependent disease characterized by ectopic growth of uterine-like cells outside the uterus. People living with endometriosis typically experience debilitating pelvic pain (dysmenorrhea, dyspareunia, dyschezia, dysuria, non-menstrual pelvic pain), and infertility. Endometriosis also has significant negative impacts on quality of life, physical, mental, and social wellbeing. There is no diagnostic marker nor cure for this chronic disease. Current treatment options include medical therapies (mainly hormonal treatments aimed at suppressing menstruation or growth of the ectopic cells), surgery (to remove endometriotic lesions/nodules), and complementary or alternative therapies (non-medical or surgical options to manage symptoms; heat, mindfulness, diet, yoga, natural remedies, physical therapies, etc.). Many people living with endometriosis report having used self-management strategies (complementary and alternative therapies) to manage their symptoms, and research on treatments and alternative therapies are consistently ranked among the top endometriosis research priorities. Alternative therapies have the potential to complement existing medical and surgical therapies, offering additional options to manage symptoms like pain.

Interventions

Intravaginal use of Hyivy device three times per week for 12 weeks, with each session consisting of 10 minutes of heat (37-39ºC) and 10 minutes of dilation.

Exclusion criteria

* 1.Chronic pelvic pain thought to be due to a condition other than endometriosis * 2.Diagnosis of premature ovarian insufficiency * 3.Any other medical condition or clinical finding giving reasonable suspicion of a disease or condition that contraindicates the use of the investigational product or that may affect the interpretation of the results or leave the patient at high risk from treatment complications, at the discretion of the investigator(s) * 4.Any surgery in the past 3 months or anticipates having surgery during the study * 5.Allergy to Hyivy device's materials * 6.Active vaginal infection (e.g. vulvovaginal candidiasis, trichomonas vaginitis, bacterial vaginosis, STIs) or infection in the pelvic area * 7.Current use of antibiotics and a history of vulvovaginal candidiasis * 8.Pregnant or lactating * 9.Currently under the care of a pelvic floor physiotherapist * 10.Have open wounds, cuts, or open sores present in vaginal or pelvic area * 11.Severe atrophic vaginitis or very dry, itchy, or sore vagina/vaginal area, at the discretion of the primary investigator(s) * 12.Hypoesthesia or loss in sensation of the pelvic floor * 13.Total and/or partial prolapse of the uterus and/or vagina * 14.Symptoms of severe urinary retention, severe extra-urethral incontinence or overflow incontinence * 15.Unable to position the device according to directions for use * 16.Use of any medical devices that may interfere with the investigational device's function, such as pacemakers, ventilators, and ear implants

Design outcomes

Primary

MeasureTime frameDescription
Overall self-reported pelvic painBaseline, 6-weeks, 12-weeksOverall pelvic pain will be evaluated using a digital visual analog scale (VAS)

Secondary

MeasureTime frameDescription
Sexual Function (FSFI)Baseline, 6-weeks, 12-weeksChanges in sexual function as assessed by the Female Sexual Function Index (FSFI). Scores range from 2 to 36 with higher scores indicating greater functioning.
Safety and tolerability of the Hyivy deviceUp to 12-weeksOccurrence of adverse events (AE) and serious adverse events (SAE).
Adherence to study protocol6-weeks, 12-weeksUsage data collected by the Hyivy device will be used to assess participant adherence to the study regimen of 3 times/week device use.
Feasibility of the Hyivy device6-weeks, 12-weeksDevice usage will be assessed with a study-specific questionnaire.
Use of rescue medicationBaseline, 6-weeks, 12-weeksChanges in the use of rescue medications for chronic pelvic pain, assessed with a study-specific questionnaire.
Site-specific tenderness and pelvic floor muscle painBaseline, 6-weeks, 12-weeksSite-specific tenderness and pelvic floor muscle pain will be measured by the Biberoglu and Behrman scale (B&B) ranging from 0 (none) to 15 (severe) and patient exams
Quality of Life (EHP-30)Baseline, 6-weeks, 12-weeksChanges in quality of life as assessed by the Endometriosis Health Profile-30 (EHP-30) ranging from 0 (best possible health status) to 100 (worst possible health status).

Other

MeasureTime frameDescription
Emergency room (ER) visitsBaseline, 6-weeks, 12-weeksNumber of ER visits due to chronic pelvic pain in the last 6 weeks
