Delivering Transcutaneous Auricular Neurostimulation to Reduce Heavy Menstrual Bleeding in Von Willebrand Disease Patients (HMB/VWD)
Delivering Transcutaneous Auricular Neurostimulation to Reduce Heavy Menstrual Bleeding in Patients With Von Willebrand Disease
Study Overview
Status
Intervention / Treatment
Detailed Description
This study is designed as an open label, decentralized clinical study in which patients with VWD and heavy menstrual bleeding (HMB) will receive tAN, which targets the auricular branch of the vagus nerve (ABVN) and the auriculotemporal nerve (ATN). Participants will be enrolled in the study over the course of two consecutive menstrual cycles.
During the First Menstruation (baseline), no tAN treatment will be delivered. Participants will estimate blood loss daily throughout the duration of the menstruation phase of their first menstrual cycle. Dysmenorrhea, a general quality of life assessment, and total duration of menstruation will be collected on the final day of first menstruation.
During the Second Menstruation, participants will self-administer 2, 1-hour sessions (daily total of 2 hours) of active tAN daily beginning Day 1 of menstruation through the final day of second menstruation. Participants will estimate blood loss daily throughout the duration of the menstruation phase of their second menstruation. Dysmenorrhea, a general quality of life assessment, and total duration of menstruation will be collected on the final day of second menstruation.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Baseline Followed by Active tAN
First Menstruation (baseline/no active tAN) followed by Second Menstruation (active tAN)
|
The Volta System will be using the components of the Sparrow Ascent device: (FDA-cleared K230796) a wearable, battery-operated, neurostimulation system designed to transcutaneously stimulate nerves on and/or around the auricle.
During Second Menstruation, participants will self-administer 2, 1-hour sessions of active tAN daily with the Volta System Device beginning Day 1 of second menstruation through the final day of second menstruation.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Blood loss during menses in von Willebrand Disease patients
Time Frame: Daily throughout both menstruations (up to 2 complete menstrual cycles- estimated 60 days)
|
Comparison of mean Pictorial Bleeding Assessment Chart (PBAC) scores during first menstruation (no stimulation) versus second menstruation (active stimulation).
The PBAC is a widely accepted tool for patients with HMB to account for menstrual blood loss.
Menstrual blood loss is estimated through a selection of images of tampons, pads, clots, and flooding events.
Patients mark a tally next to the images that best match each of the menstruation products they used that day.
This trial will utilize a modified version of the Wyatt et al. 2001 PBAC, where a tally system will be added to each of the images.
|
Daily throughout both menstruations (up to 2 complete menstrual cycles- estimated 60 days)
|
Quality of Life of von Willebrand Disease patients
Time Frame: Final day of each menstruation (up to 2 complete menstrual cycles- estimated 60 days)
|
Comparison of mean quality of life score measured by the Short Form 36 (SF-36) during first menstruation (no stimulation) versus second menstruation (active stimulation).
The SF-36 is a 36-item patient-reported questionnaire that assesses general quality of life.
This questionnaire includes eight variables: physical functioning, social functioning, role limitations due to physical problems, role limitations due to emotional problems, mental health, energy and vitality, pain, and general perception of health.
The SF-36 is scored using a standardized scoring algorithm or by the SF-36 scoring software.
The SF-36 scores range from 0 to 100, with higher scores representing better health status.
|
Final day of each menstruation (up to 2 complete menstrual cycles- estimated 60 days)
|
Duration and severity of dysmenorrhea in von Willebrand Disease patients
Time Frame: Final day of each menstruation (up to 2 complete menstrual cycles- estimated 60 days)
|
Comparison of mean Cox Menstrual Symptom Scale (CMSS) scores during first menstruation (no stimulation) versus second menstruation (active stimulation).
The CMSS measures menstrual distress and dysmenorrhea.
The CMSS Severity subscale is an 18-item self-reported scale that measures severity of menstrual symptoms, including pain, nausea, emotions, etc. during menstruation.
The CMSS will be used in this trial to measure a participant's dysmenorrhea every day of each menstruation.
Each CMSS item is scored from 0-4, with a higher score indicating higher dysmenorrhea severity.
|
Final day of each menstruation (up to 2 complete menstrual cycles- estimated 60 days)
|
Duration of menstruation in von Willebrand Disease patients
Time Frame: Final day of each menstruation (up to 2 complete menstrual cycles- estimated 60 days)
|
Compare duration of menstruation between first menstruation (no stimulation) versus second menstruation (active stimulation).
|
Final day of each menstruation (up to 2 complete menstrual cycles- estimated 60 days)
