Detailed Description

This is an initial Phase I single-site, single-arm, double-baseline repeated measures feasibility study of wearable focal vibration (FV with Myovolt) for persistent chemotherapy-induced peripheral neuropathy. We will enroll up to 15 cancer survivors who are cancer-free and meet all other inclusion/ exclusion criteria, including CIPN symptoms at least 3 months after final chemotherapy infusion. Participants will undergo baseline assessments (V1) of questionnaires and performance tests, and may repeat these tests within a few days as a double-baseline (V2). In addition, they complete 7-days of baseline symptom monitoring by diary before starting 6 weeks of daily at-home therapy with a Myovolt wearable FV device. A study coach will check in by phone or video calls during the intervention period. Participants undergo post-testing immediately after the 6-week intervention (V3), and after another 6 weeks without FV (V4). In total, participants attend 3-4 onsite study visits, a 6-week intervention period with weekly remote check-in contact from the study team, and a 6-week intervention-free follow-up period with at least one remote check-in. Participants will keep a provided daily symptom diary during the primary study period (i.e., 6 weeks), and at least weekly in the 6-week follow-up period.

Eligibility Criteria

Eligibility Criteria

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.

Exclusion Criteria:

  • Neuropathy (known or suspected) of any etiology other than chemotherapy or diabetes (for example, due to alcohol, vitamin deficiency, autoimmune disorder, CMT, idiopathic
  • Unsafe/unable to self-apply the focal vibration intervention for any reason (for example, insufficient hand dexterity or cognitive executive function

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Focal vibration therapy
Myovolt delivers vibration with a frequency between 50-80 Hz. Myovolt intensity will be set to ~up to 2X the participant's initial Myovolt perception threshold. If the stimulation does not feel strong, the participant will be asked to manually increase the intensity until it feels strong but comfortable.
Device: Focal vibration therapy
Myovolt is a wearable rehabilitative device that delivers vibration to the region of the body where the motors are worn. Participants are asked to apply the vibration to specific leg locations twice a day, for about 30 minutes at a time, and to record their response using a provided log. They may be asked to try applying the device at different location or using different vibration parameters (pulse frequency or intensity).

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
Feasibility of Enrollment
Time Frame: Baseline
Percent of interested individuals who enrolled.
Baseline
Adherence to Myovolt Focal Vibration
Time Frame: After 6-week intervention
Number of completed sessions the intervention was worn, as a percentage of the number of sessions prescribed.
After 6-week intervention

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
Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity-12 (FACT-GOG/NTX-12) Symptom Inventory
Time Frame: Change from Baseline after 6-week Intervention
The FACT-GOG/Ntx-12 is a composite measure of CIPN symptoms and functional impairments and related quality of life, scored from 0 to 48 where a higher score indicates worse neuropathy symptoms.
Change from Baseline after 6-week Intervention
Neuropathy Total Symptom Score-6 (NTSS-6)
Time Frame: Change from Baseline after 6-week Intervention
The NTSS-6 rates neuropathic symptoms (severity and frequency) in 6-categories. Scores range from 0 to 21.96, and higher scores indicate higher symptom burden.
Change from Baseline after 6-week Intervention
Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity-12 (FACT-GOG/NTX-12) Physical Well-Being Subscale
Time Frame: Change from Baseline after 6-week Intervention
The FACT-GOG/Ntx-12 PWB subscale is a patient-report measure of physical symptoms and function. Scored from 0 to 28, higher scores indicate better well-being.
Change from Baseline after 6-week Intervention
Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity-12 (FACT-GOG/NTX-12) Functional Well-Being Subscale
Time Frame: Change from Baseline after 6-week Intervention
The FACT-GOG/Ntx-12 FWB subscale is a patient-report measure of functional well-being with questions about work, leisure and sleep, and a summary quality of life(QoL)rating. Scores range from 0 to 28, higher scores indicate better well-being and QoL.
Change from Baseline after 6-week Intervention
Patient Neurotoxicity Questionnaire (PNQ)
Time Frame: Change from Baseline after 6-week Intervention
The PNQ grades the extent of sensory and motor neuropathy in cancer cohorts scored from grade A (no neuropathy, also Grade 0) to grade E (severe neuropathy, also Grade 4). Sensory and motor severity are rated separately.
Change from Baseline after 6-week Intervention
Global Rating of Change (GROC) Scale
Time Frame: After 6-week intervention
The GROC scale is a universal clinical outcome providing a simple but comprehensive "umbrella" patient-perspective of change. Scores on a 9-point ordinal scale centered around 0 (Unchanged) ranged from -4 (very much worse) to 0 (unchanged) to +4 (very much better).
After 6-week intervention
Manual Muscle Testing (MMT) of Toes
Time Frame: Change from Baseline after 6-week Intervention
MMT assesses muscle strength by an assessor applying pressure against the hallux as the participant lifts and holds 1st metatarsophalangeal extension. Strength is rated from 0 (weakest) to 5 (strongest). Change of 1 grade from the baseline values is categorized as improvement or decline.
Change from Baseline after 6-week Intervention
Change in Toe Strength Using a Proprietary Quantifiable Toe Measurement Device, Quantification of Hallux Extension Strength or QuHalEx(TM), U.S. Patent 11402284 Issued to the University of Oklahoma on 08/02/2022, and Provisional Patent 63/627,850.
Time Frame: Change from Baseline after 6-week Intervention
QuHalEx(TM) measures toe strength by reading force measurements (higher is stronger) when participants sit with foot strapped on a portable base of a proprietary University of Oklahoma QuHalEx(TM) load-cell prototype device (U.S. Patent 11402284 issued to the University of Oklahoma on 08/02/2022, and provisional patent 63/627,850). With the great toe inserted into a cap, the participant pulls up and holds isometrically for a few seconds. The peak force is the highest value recorded over the hold time. We report the change in peak force from baseline to the 6-week visit.
Change from Baseline after 6-week Intervention
Vibration Perception Threshold Using Biothesiometer
Time Frame: Change from Baseline after 6-week Intervention
Vibratory threshold is measured by a non-invasive vibrating probe (biothesiometer) placed on the skin and increased from 0 Hz until the amplitude when the participant first reports detection (eyes closed) or the maximum amplitude available on the biothesiometer scale (50 Volts). Higher indicates worse sensation.
