Exclusion Criteria

Individuals will be excluded from pilot study participation if they:

• Have a serious medical, psychiatric or substance use disorder that, in the opinion of the study physician, would make study participation hazardous to the participant, compromise study findings, or prevent the participant from completing the study.

Examples include:

• Disabling or terminal medical illness (e.g., active opportunistic infection, uncompensated heart failure, cirrhosis or end-stage liver disease, acute hepatitis and moderate to severe renal impairment) as assessed by medical history, review of systems, physical exam and/or laboratory assessments;
• Severe, untreated or inadequately treated mental health disorder (e.g., active psychosis, uncontrolled manic-depressive illness) as assessed by history and/or clinical interview;
• Current severe benzodiazepine or other depressant or sedative hypnotic use requiring medical detoxification;
• Suicidal or homicidal ideation requiring immediate attention.
• Have aspartate aminotransferase (AST) or alanine aminotransferase (ALT) liver enzymes greater than 5 times upper limit of normal on screening phlebotomy. Results from tests conducted within the past 30 days which are abstracted from medical record information are acceptable.
• Have international normalized ratio (INR) > 1.5 or platelet count <100k. Results from tests conducted within the past 30 days which are abstracted from medical record information are acceptable.
• Have known allergy or sensitivity to naloxone, naltrexone, polylactide-co-glycolide, carboxymethylcellulose, or other components of the Vivitrol® diluents.
• Anticipate undergoing surgery during study participation.
• Have chronic pain requiring ongoing pain management with opioid analgesics.
• Pending legal action or other reasons that might prevent an individual from completing the study.
• Currently pregnant or breastfeeding.
• Body habitus that, in the judgment of the study physician, precludes safe intramuscular injection of XR-NTX, (e.g. excess fat tissue over the buttocks).
• Received methadone or buprenorphine maintenance therapy for treatment of opioid dependence in the 4 weeks prior to screening.
• Have taken an investigational drug in another study within 30 days of study consent.
• Have ECG findings that, in the opinion of the study medical clinician would preclude safe participation in the study. Results from ECGs conducted within the past 30 days which are abstracted from medical record information are acceptable.
• Have had treatment with XR-NTX for opioid or alcohol dependence in the 3 months prior to screening.
