NCT01556425

Brief Summary

In this 5-year study, the investigators propose to evaluate the separate and combined effects of the FDA-approved formulation of extended release naltrexone (Vivitrol®) and employment-based reinforcement of opiate abstinence in promoting opiate abstinence and reducing risky injection behavior in recently detoxified, opioid-dependent, injection drug users.

Outcome Measures

Primary Outcomes (1)

  • Percent of Weekly Urine Samples Negative for Opiates

    Was the participant's urine sample negative for opiates at each of the 24 weekly assessments scheduled after random assignment (Y/N)? The outcome measure was the percentage of weekly urine samples that was negative for opiates.

    24 weeks

Secondary Outcomes (1)

  • Percent of Weekly Urine Samples Negative for Cocaine

    24 weeks

Study Arms (4)

Vivitrol Only

EXPERIMENTAL

The VIVITROL group will be offered one injection of VIVITROL every 4 weeks. Participants in the VIVITROL group will be required to take their scheduled injections to work and earn wages. If a participant misses a scheduled VIVITROL injection (more than 3 days from the scheduled date of administration), the participant will not be allowed to work until the injection is accepted. Additionally, missing a scheduled injection will result in a base pay reset from $8 per hour to $1 per hour. After the reset, the participant's base pay will increase by $1/hour to the maximum of $8/hour for every day that the participant works at least 5 minutes.

Drug: Vivitrol

VIVITROL&Opiate Abstinence Reinforcement

EXPERIMENTAL

This group will be offered VIVITROL and will be required to take it to attend the workplace and to maintain maximum pay. This group will also receive employment-based opiate abstinence reinforcement. This contingency will require participants to provide opiate-negative urine samples on M,W, and F to maintain their maximum pay. If a participant in this group provides an opiate-positive urine sample, or fails to provide a scheduled sample, their base pay will be reset from $8 per hour to $1 per hour. On each day after the reset that the participant provides a urine sample that meets the opiate abstinence criteria and attends the workplace for at least 5 minutes, their base pay will increase by $1 per hour until it reaches the maximum of $8 per hour.

Drug: VivitrolBehavioral: Employment-based opiate abstinence reinforcement

Opiate Abstinence Reinforcement Only

EXPERIMENTAL

This group would receive employment-based opiate abstinence reinforcement, but this group will not receive VIVITROL.

Behavioral: Employment-based opiate abstinence reinforcement

Usual Care Control

OTHER

This group will receive neither abstinence reinforcement nor VIVITROL injections, but they will be invited to attend the workplace and outpatient drug abuse counseling.

Other: Usual Care Control

Interventions

Participants receiving this intervention will receive the FDA-approved dose, route, and schedule of administration of VIVITROL. The dose of VIVITROL of 380 mg will be delivered intramuscularly every 4 weeks.

VIVITROL&Opiate Abstinence ReinforcementVivitrol Only

This intervention will require participants to provide opiate-negative urine samples on Monday, Wednesday and Friday to maintain their maximum pay. If a participant provides an opiate-positive urine sample, or fails to provide a scheduled sample, their base pay will be reset from $8 per hour to $1 per hour. On each day after the reset that the participant provides a urine sample that meets the opiate abstinence criteria and attends the workplace for at least 5 minutes, their base pay will increase by $1 per hour until it reaches the maximum of $8 per hour.
