Study 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.

Primary Outcome

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 indic
