Outcomes

Primary Outcome Measures

Clinical opiate withdrawal scale (COWS) score
Mean percent change in clinical opiate withdrawal scale (COWS) score from baseline to 60 minutes after start of active tAN therapy. The COWS is an 11-item scale with a score range between 0 and 48. Total score is the sum of all the items and a higher score indicates more severe withdrawal symptoms. Scores between 5 and 12 indicate mild withdrawal, scores between 13 and 24 indicate moderate withdrawal, scores between 25 and 36 indicate moderately severe withdrawal and scores greater than 36 indicate severe withdrawal. A COWS score reduction of 15% or greater for a given individual is considered clinically significant.

Secondary Outcome Measures

Clinical opiate withdrawal scale (COWS) score
Comparison of mean percent change in COWS score in delayed active tAN versus active tAN groups at 30 minutes
Clinical opiate withdrawal scale (COWS) responder rate
Comparison of the proportion of participants with a clinically significant reduction in COWS score (defined as a 15% or greater reduction) in delayed-active tAN versus active tAN groups at 30 minutes
Clinical opiate withdrawal scale (COWS) score
Mean percent change in COWS score from baseline to 30 minutes after start of active tAN therapy
Clinical opiate withdrawal scale (COWS) score
Mean percent change in COWS score from baseline to 120 minutes after start of active tAN therapy
Clinical opiate withdrawal scale (COWS) score
Mean percent change in COWS score from baseline to Days 2 through 5 after start of active tAN therapy

5. Study Description

Brief Summary
Clinical performance data for transcutaneous auricular neurostimulation (tAN) as a method to aid in the reduction of symptoms associated with opioid withdrawal in order to support clinical substantial equivalence to a predicate device.
Detailed Description
Prior evidence has demonstrated that non-invasive neurostimulation can modulate specific brains regions associated with opioid use disorder and reduce opioid withdrawal symptoms. This is a double blind, randomized, controlled, multi-center study in which subjects will be randomized in a 1:1 ratio to one of two groups: 1) active transcutaneous auricular neurostimulation (tAN) or 2) delayed-active tAN to determine reduction of symptoms related to opioid withdrawal. Subjects in the active tAN group will receive tAN immediately whereas those in the delayed-active tAN will have their therapy turned on after a 30 minute delay (inactive period). All subjects will be informed of their group assignment at the conclusion of the randomized, double blind period (following initial 30 minutes of active or inactive therapy) and all will continue to receive active tAN throughout the five-day study. Each clinical site will have pre-determined and qualified clinical opiate withdrawal scale (COWS) accessor(s) that will be blind to the subjects group designation during the randomized, double blind period and will not be informed that all subjects receive active therapy throughout the remainder of the study. This will ensure a non-biased assessment of the COWS score and maintain single blinding throughout the duration of the study.

Patient Health Questionnaire (PHQ-9)
Description
Mean change in depression symptoms measured by Patient Health Questionnaire (PHQ-9) total score from baseline to Day 5. The PHQ-9 is a nine-item depression scale based directly on the nine diagnostic criteria for major depressive disorder in the DSM-IV. Each of the nine items is rated on a 0 (not at all) to 3 (nearly every day) scale. A total score is calculated by summing the nine items. Scores range from 0 to 27 and higher scores indicate a higher degree of depression.

Day 5
Title
Post-Traumatic Stress Disorder (PTSD) Checklist for DSM-5 (PCL-5)
Description
Mean change in PTSD symptoms measured by the PTSD Checklist for DSM-5 (PCL-5) total symptom severity score from baseline to Day 5. The PCL-5 is a 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD. Each of the 20 items is rated on a 0 (not at all) to 4 (extremely) scale. A total symptom severity score is calculated by summing the 20 items. Scores range from 0 and 80 and higher scores indicating a higher degree of PTSD symptomology. Evidence suggests that a10-20 point reduction in score represents a clinically significant change in PTSD symptoms.
Time Frame
Day 5
Title
World Health Organization Quality of Life - BREF (WHOQOL-BREF)
Description
Mean change in WHOQOL-BREF domain scores (physical health, psychological health, social relationships, environment, and overall QoL/general health) from baseline to Day 5. The World Health Organization Quality of Life - BREF (WHOQOL-BREF) is a 26-item, self-report questionnaire which assesses 4 quality of life domains: physical health, psychological health, social relationships, and environment. In addition, there are 2 items that measure overall quality of life and general health. Subjects rate how much they have experienced each item in the preceding 2 weeks on a 5-point Likert scale ranging from 1 (not at all) to 5 (completely). Domain scores are scaled in a positive direction with higher scores denoting higher quality of life. Raw domain scores will be converted to a 0 to 100 scale.
