  Purpose

The purpose of this study is to evaluate a very low dose naltrexone-buprenorphine treatment to transfer opioid dependent individuals to extended release naltrexone injection (Vivitrol). The hypothesis is that patients will complete the transfer to Vivitrol successfully, finding the treatment acceptable and showing minimal withdrawal discomfort.

Primary Outcome Measures:
  • Retention in Treatment [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    After the initial titration period for opioid withdrawal (of up to 8 days), patients will receive the Vivitrol injection. Then, we will follow patients for retention out to 4 weeks and record the total time they remained in treatment.


Secondary Outcome Measures:
  • Withdrawal Intensity (COWS) [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]

    After the initial titration period for opioid withdrawal (of up to 8 days), patients will receive the Vivitrol injection. Then, we will follow patients for retention out to 4 weeks and record the total time they remained in treatment.

    COWS = Clinical Opiate Withdrawal Scale. COWS rates eleven common opiate withdrawal signs or symptoms. The summed scores are used in the assessment 5-12 = mild; 13-24 = moderate; 25-36 = moderately severe; more than 36 = severe withdrawal


  • Withdrawal Intensity (SOWS) [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]

    After the initial titration period for opioid withdrawal (of up to 8 days), patients will receive the Vivitrol injection. Then, we will follow patients for retention out to 4 weeks and record the total time they remained in treatment.

    SOWS = Subjective Opiate Withdrawal Scale. SOWS contains 16 symptoms whose intensity the patient rates on a scale of 0 (not at all) to 4 (extremely).

Arms Assigned Interventions
Experimental: BUP/VLNXT to VIVITROL
On days 1-4, participants will receive buprenorphine/naloxone daily at a starting dose of between 4 to 8 mg, progressively decreasing to 2 mg on by day 4. Participants will also receive very low dose naltrexone (VLNTX) at a dose of 0.25 mg on Days 1-3, 2.5 mg on Day 4 and between 10 and 50 mg on Days 5-7. Then a VIVITROL (extended release naltrexone) injection, 380 mg, will be administered on Day 8.
Drug: very low dose naltrexone
On days 1-4, participants will receive buprenorphine/naloxone daily, starting at a dose of 4 to 8 mg, progressively decreasing to 2 mg on Days 1-4 and very low dose naltrexone at 0.25 mg on Days 1-3, 2.5 mg on Day 4 and 10 mg to 50 mg on Days 5-7. VIVITROL injection will be administered on Day 8 at 380 mg.
Drug: extended release naltrexone
On days 1-4, participants will receive buprenorphine/naloxone daily, starting at a dose of 4 to 8 mg, progressively decreasing to 2 mg on Days 1-4 and very low dose naltrexone at 0.25 mg on Days 1-3, 2.5 mg on Day 4 and 10 mg to 50 mg on Days 5-7. VIVITROL injection will be administered on Day 8 at 380 mg.
Other Name: Vivitrol
Drug: buprenorphine/naloxone
On days 1-4, participants will receive buprenorphine/naloxone daily, starting at a dose of 4 to 8 mg, progressively decreasing to 2 mg on Days 1-4 and very low dose naltrexone at 0.25 mg on Days 1-3, 2.5 mg on Day 4 and 10 mg to 50 mg on Days 5-7. VIVITROL injection will be administered on Day 8 at 380 mg.
Other Name: Suboxone

Detailed Description:

Twenty opioid dependent (OD) volunteers seeking treatment will be enrolled in an open-label, flexible-dosing, outpatient trial at Duke Addictions Program. On days 1-4, participants will receive buprenorphine/naloxone daily at a starting dose of between 4 to 8 mg, progressively decreasing to 2 mg on by day 4. Participants will also receive very low dose naltrexone (VLNTX) at a dose of 0.25 mg on Days 1-3, 2.5 mg on Day 4 and between 10 and 50 mg on Days 5-7. Then a VIVITROL injection, 380 mg, will be administered on Day 8.

Evaluations will occur daily for up to 6 hours until 1 day after VIVITROL injection and then weekly for 4 weeks. Patients will receive ancillary medications as needed and weekly psychosocial intervention. At the end of the study, participants will be offered outpatient treatment of OD at the study site, or will be referred to other treatment programs.
