Outcome Measures

Primary Outcomes (1)

  • 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.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

  • COWS score is ≥ 13 or in the opinion of the investigator the subject is in moderate to severe withdrawal
  • years of age
  • English Proficiency
  • Participants must be able to provide informed con-sent and function at an intellectual level sufficient for study requirements

You may not qualify if:

  • Current evidence of an uncontrolled and/or clinically significant medical condition
  • History of seizures or epilepsy
  • History of neurological diseases or traumatic brain injury
  • Participants using long-acting opioids such as methadone or buprenorphine for a period of five or more consecutive days prior to enrollment
  • Recent suicide attempt leading to current hospital admission or continued expressed suicidal ideation
  • Presence of devices, e.g. pace-makers, cochlear prosthesis, neuro-stimulators
  • Abnormal ear anatomy or ear infection present
  • Women of childbearing potential, not using adequate contraception as per investigator judgment or not willing to comply with contraception for the duration of the study
  • Females who are pregnant or lactating
  • Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant's ability to participate in the trial
