Transcutaneous Auricular Neurostimulation (tAN) for Symptoms of Opioid Withdrawal

Spark Biomedical, Inc.35 enrolled

Overview

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.

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.
