Summary

This trial is testing a device called the Bridge Device, which uses electrical signals to help people with opioid addiction. The study focuses on individuals who are not currently on any medication for their addiction. The device aims to ease withdrawal symptoms by sending signals to the brain. Participants will be monitored to see if the device effectively reduces withdrawal symptoms.

Who is the study for?
This trial is for adults aged 18-65 with Opioid Use Disorder seeking treatment, who are in good health and not using opioid agonist treatments or have significant medical conditions like heart issues, liver or kidney impairment. Participants must test positive for opioids or show withdrawal symptoms but can't be pregnant, breastfeeding, or have certain psychiatric illnesses.
What is being tested?
The study tests the Bridge Device (BD), a neuromodulator cleared by the FDA for OUD treatment. It compares three groups: one with active BD and placebo pills, another with a sham BD and lofexidine (a non-opioid medication to ease withdrawal), and a third group with both sham BD and placebo. The efficacy of these interventions during opioid withdrawal will be evaluated over several weeks.
What are the potential side effects?
Possible side effects include skin irritation from the device, blood pressure changes due to lofexidine, potential allergic reactions to study medications, fatigue from naloxone-induced withdrawal challenges during the trial period.

Other Research
The most common treatments for opioid addiction include neuromodulation, buprenorphine, and naltrexone. Neuromodulation, such as the Bridge Device, aims to alleviate withdrawal symptoms by stimulating specific nerves, potentially reducing the discomfort associated with opioid withdrawal. Buprenorphine is a partial opioid agonist that binds to opioid receptors, reducing cravings and withdrawal symptoms without producing the same high as other opioids, thus lowering the risk of misuse. Naltrexone is an opioid antagonist that blocks opioid receptors, preventing the euphoric effects of opioids and helping to maintain abstinence. These treatments are crucial for opioid addiction patients as they address both the physical dependence and the psychological aspects of addiction, improving the chances of successful recovery.
