Overview
Brief Summary
This is a single-center, randomized, open-label, single-dose, parallel-group study which will enroll and randomize approximately 48 subjects (to achieve 36 completers) with opioid use disorder (OUD) who are seeking treatment for OUD. The study includes both a Residential (Inpatient) and Non-Residential (Outpatient) Period.

- •Had a significant traumatic injury, major surgery, or open biopsy within the 4 weeks prior to signing the informed consent form.
- •Used buprenorphine-containing products within the 14 days prior to signing the informed consent form.
- •Have a history of suicidal ideation within the 30 days prior to signing the informed consent form or prior to study drug administration
- •Have a history or presence of allergic or adverse response (including rash or anaphylaxis) to buprenorphine, naloxone, methadone, or the ATRIGEL Delivery System.
