简要总结
The Nu-V3 Clinical Study is a prospective, single-arm, open-label, multi-center study using the Nu-V3 cranial nerve stimulation treatment device in patients with chronic pain, anxiety, depression, and/or sleeplessness.
For this Phase II study, a total of 100-200 patients at multiple centers will be registered for study participation. Study participants are those who have signed the informed consent form, met the inclusion and exclusion criteria, and are enrolled in the study at one of multiple sites. Enrolled participants are stratified based on their chronic pain, anxiety, depression, and/or sleeplessness symptom presentation at baseline and treated with the Nu-V3 device for 24 weeks. Interim analysis of reported data will be based on baseline stratifications and conducted at 6, 12, 18, and 24 weeks during this time. The participant will be evaluated after the initial 12-week treatment period to assess for further therapeutic need. Upon having three consecutive weeks of mean symptom reduction of ≥70% via patient reported numerical scales, the participant will continue as described in the study assessments table, but without device therapy. Then if the participant's primary symptom score increases at any time by ≥20%, they may again continue device therapy until week 24.
详细描述
Subjects enrolled onto the Nu-V3 Clinical Trial will undergo the following regimen:
- At the baseline visit, patients will be asked to complete study questionnaires regarding all of the following symptoms: chronic pain, anxiety, depression, and/or sleeplessness, as well as their quality of life, active medications, medical history, and demographic information. The subject's primary symptom of concern will also be notated at baseline, for later assessment of continuation after week 12.
- At each subsequent visit, patients will be asked to complete study questionnaires regarding all the following symptoms: chronic pain, anxiety, depression, and/or sleeplessness, as well as their activity level and quality of life.
- The sessions will begin with the Nu-V3 device being clipped on the ear and three small pads (non-invasive) adhered to the surface of the ear. Each Nu-V3 device lasts for up to 14 days with a change in the pads approximately 7 days into the treatment.
- Each session takes approximately 15-20 minutes. The placement of the device takes approximately 5 minutes and the remaining time is spent verifying ePRO form completion, and evaluating the patient for all device effects.
- The Nu-V3 device is mobile and is worn externally on the left ear 24 hours a day during treatment, fitting comfortably behind the ear. An electrical signal is sent to the external ear through coated wire leads attached to the device and adhesive pads which attach to three sites on the ear.
- Participants should be able to perform their typical day-to-day activities while wearing the device. They may shower while wearing the Nu-V3 device, provided that they do not get the device wet and use the small disposable ear covers that are provided for them.
- In the event the Nu-V3 gel pads are inadvertently removed or the device comes off, the participant will contact the site coordinator. The participant is encouraged to adjust the device placement as needed for comfort.
- Patients should not change their existing forms of treatment or medications without discussion with the study investigator.

结局指标
主要结局
Effectiveness and overall change in reported primary symptom of concern: Chronic Pain
时间窗: 12 and 24 weeks
Chronic Pain - (PEG Scale) The PEG is a three-item instrument that measures pain intensity (one item) and pain interference (two items). The PEG is a three-item instrument that measures pain intensity (one item) and pain interference (two items). Each item is valued from 0 (no pain/interference) to 10 (as bad as you can imagine). The instrument score is calculated as the average of the three item values.
Effectiveness and overall change in reported primary symptom of concern: Anxiety
时间窗: 12 and 24 weeks
Anxiety - (GAD-7)The GAD-7 is a seven-item instrument that measures respondents' symptoms of anxiety. The GAD-7 is a seven-item instrument that measures respondents' symptoms of anxiety. Each item is scored on a four-point Likert scale, and values range from 0 ("Not at all") to 3 ("Nearly every day".) Items are summed to determine the instrument's score. Values of 10 or higher have been associated with moderate anxiety, while values of 15 or higher have been associated with severe anxiety.
Effectiveness and overall change in reported primary symptom of concern: Depression
时间窗: 12 and 24 weeks
Depression - (PHQ-9) The PHQ-9 is a nine-item instrument that measures depression-related symptoms and functional impairment. The PHQ-9 is a nine-item instrument that measures depression-related symptoms and functional impairment. Each item is scored on a four-point Likert scale and values range from 0 ("Not bothered at all") to 3 ("Bothered nearly every day.") The items' values are summed to determine the instrument's score. PHQ-9 values of 10 and 15 represent moderate and moderately severe depression respectively.
