Brief summary

This project is being completed to test the usability and safety of the Watch-Transcutaneous Electrical Acustimulation (TEA) Device. This is a pilot study that will lead to future projects for cancer patients that may experience chemotherapy-induced symptoms.

Detailed description

This project will include three different aims (aim three is a clinical trial) and will be funded by the National Institute of Health (NIH). In aims 1 and 2 the device hardware and device application will be developed and will not be included in this registration as these are not clinical trials. However, aim three is being registered early in the project in order to obtain the Notice of Award (NOA) funding from the NIH. Once the NOA has been obtained the registration will be updated.

Interventions

DEVICEWatch-TEA group

Subjects will wear the device for 3 days. The subjects will self-apply the TEA for 60 min once daily with the current amplitude set at a maximal tolerable level. To increase the subject compliance, two measures will be implemented: timely alerts by the app (and phone calls, if needed) for performing the TEA sessions, and recording full history of therapy sessions on the device for monitoring the compliance.

DEVICETethered TEA device

Subjects will wear the device for 3 days. The subjects will self-apply the TEA for 60 min once daily with the current amplitude set at a maximal tolerable level. To increase the subject compliance, two measures will be implemented: timely alerts by the app (and phone calls, if needed) for performing the TEA sessions, and recording full history of therapy sessions on the device for monitoring the compliance.

Intervention model description

Prevalence of delayed Chemotherapy-induced nausea, emesis, and dyspeptic symptoms (CINEDS) is 75% in women vs 51% in men (60% to 40% ratio). Therefore, every effort will be made to recruit at least 60% female subjects into the clinical study.

Inclusion criteria

* Participants that are willing and able to come to the clinic for two scheduled visits * Participants are capable of understanding clinical study procedures * Participants agree to complete the questionnaires

Exclusion criteria

* Participants with implanted medical devices for electrical stimulation (e.g. cardiac pacemaker) * Those enrolled in a concurrent clinical study * Those unable to comply with the study protocol due to a disease, psychiatric illness, alcoholism, substance abuse, geographic distance, or other factors that would place the study participant at increased risk or preclude the study participant's full compliance with or completion of the study

Design outcomes

Primary

MeasureTime frameDescription
Usability of the device for both groups day 3Day 3Questionnaires are administered online and there are 17 usability questions in the questionnaire. All answers use 0-to-5 scale (0 - no,1 - minor, 2 - some, 3 - considerable, 4 - major, 5 - critical) with a range of 0-85 with a higher score meaning more usable.
Number of adverse events related to the device noted on the safety questionnaire1-2 weeks (after baseline visit 1)A safety questionnaire with 3 questions about skin irritation, pain, or infection. Visit 2 is at 1-2 weeks after visit 1.
Number of Transcutaneous Electrical Acustimulation (TEA)-related adverse events for both groups 3 daysDay 3These will include skin irritation, pain, or infection under the Watch-TEA and tethered TEA devices after wearing each device for 3 consecutive days. Adverse events will be noted by the following: 1. \- Mild averse event (AE) - No treatment needed 2. \- Moderate AE - Resolved with treatment 3. \- Severe AE - Inability to carry on normal activities, required professional medical attention 4. \- Life-threatening or disabling AE 5. \- Fatal AE
Number of TEA-related adverse events for both groups 60 minutes at maximal tolerable levelDaily for 3 daysThe subjects will self-apply the TEA for 60 minutes once daily with the current amplitude set at a maximal tolerable level. Events collected will include skin irritation, pain, or infection. Adverse events will be noted by the following: 1. \- Mild AE - No treatment needed 2. \- Moderate AE - Resolved with treatment 3. \- Severe AE - Inability to carry on normal activities, required professional medical attention 4. \- Life-threatening or disabling AE 5. \- Fatal AE
Number of non-treatment TEA adverse events for both groupsup to 1-2 weeks (after baseline visit 1)Adverse events will be noted by the following: 1. \- Mild AE - No treatment needed 2. \- Moderate AE - Resolved with treatment 3. \- Severe AE - Inability to carry on normal activities, required professional medical attention 4. \- Life-threatening or disabling AE 5. \- Fatal AE
