Comparing Treatments for HIV-Infected Opioid and Alcohol Users in an Integrated Care Effectiveness Study

Phase 3

Completed

• Conditions: Opioid Use Disorder; Alcohol Use Disorder
• Interventions: Other: Treatment As usual; Drug: Extended Release Naltrexone

• Registration Number: NCT01908062
• Lead Sponsor: Oregon Health and Science University

Brief Summary

The purpose of this study is to learn how best to treat substance use disorders in an HIV clinic setting. Specifically, the purpose of this pilot study is to learn if extended-release naltrexone (XR-NTX) would be a feasible and acceptable treatment for HIV-infected individuals with opioid or alcohol use disorders.

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:

1. 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;

   1. Severe, untreated or inadequately treated mental health disorder (e.g., active psychosis, uncontrolled manic-depressive illness) as assessed by history and/or clinical interview;
   2. Current severe benzodiazepine or other depressant or sedative hypnotic use requiring medical detoxification;
   3. Suicidal or homicidal ideation requiring immediate attention.

2. 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.

3. 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.

4. Have known allergy or sensitivity to naloxone, naltrexone, polylactide-co-glycolide, carboxymethylcellulose, or other components of the Vivitrol® diluents.

5. Anticipate undergoing surgery during study participation.

6. Have chronic pain requiring ongoing pain management with opioid analgesics.

7. Pending legal action or other reasons that might prevent an individual from completing the study.

8. Currently pregnant or breastfeeding.

9. 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).

10. Received methadone or buprenorphine maintenance therapy for treatment of opioid dependence in the 4 weeks prior to screening.

11. Have taken an investigational drug in another study within 30 days of study consent.

12. 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.

13. Have had treatment with XR-NTX for opioid or alcohol dependence in the 3 months prior to screening.

Arm && Interventions

Group	Intervention	Description
Treatment as Usual	Treatment As usual	The current standard of care for treatment of opioid use disorders in HIV clinics is opioid agonist therapy. HIV-infected patients with alcohol use disorders are typically referred for residential, outpatient, and self-help groups.
Extended Release Naltrexone	Extended Release Naltrexone	Extended release naltrexone (XR-NTX), delivered by monthly injection. Dose: 380 mg. Frequency: One injection per month, for four months. Duration: 30 days.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Successful Initiation of Treatment Within 4 Weeks of Randomization	4 weeks	Successful induction onto XR-NTX or initiation of treatment as usual within 4 weeks of randomization.
Number of Participants Successfully Retained on Pharmacotherapy Treatment at 16 Weeks	16 weeks	Number of participants who received the maximum possible expected doses of XR-NTX, or the full course of recommended pharmacotherapy treatment for treatment as usual (TAU) arm.

Secondary Outcome Measures

Name	Time	Method
HIV Viral Suppression at 16 Weeks	16 weeks	Plasma HIV viral load of \< 200 copies/mL compared with screening

Mean Days of Opioid Use in Past 30 Days	Baseline and 16 weeks	Change in 30 day opioid use by Addiction Severity Index (ASI)-lite self-report and Time-Line Follow Back in the final 30 days of the 16 week trial compared to screening.
Participant Safety: Change in Liver Enzymes Between Baseline and Week 16	Baseline and 16 weeks	Change in liver enzymes between screening and Week 16. AST = Aspartate transaminase ALT = Alanine transaminase
Number of Participants With Urine Drug Screen (UDS) Positive for Opioids	Baseline and 16 weeks
Mean Days of Alcohol Use in Past 30 Days	Baseline and 16 weeks	Change in 30 day alcohol use by Addiction Severity Index (ASI)-lite self-report and Time-Line Follow Back in the final 30 days of the 16 week trial compared to screening.
Number of Participants With Urine Ethyl Glucuronide (EtG) Positive for Alcohol	Baseline and 16 weeks
Participant Safety: Any Fatal or Non-fatal Overdose Between Baseline and Week 16	16 weeks
