NCT02867124

Brief Summary

This proposed five-year study will focus on whether the addition of providing XR-NTX treatment at a patients' place of residence will increase adherence and thus efficacy of the medication.Following initial screening, informed consent, and medical examination, pre-release prisoners at each facility will be block randomized (N=240) within gender to either: Condition 1. XR-NTX-OTx (n=120): One injection of XR-NTX in prison, followed by six monthly injections post-release in the community at an opioid treatment program; or Condition 2. XR-NTX+MMTx (n=120): One injection of XR-NTX in prison, followed by six monthly injections post-release in the community at the patient's place of residence.

Outcome Measures

Primary Outcomes (6)

  • treatment adherence

    XR-NTX+ MMTx vs. XR-NTX-OTx following release from prison

    six months

  • Any illicit opioid used

    defined as continuous counts of days and urine toxicologies for heroin or other illicit opioid

    1,2,3,4,5,6,7 and 12-months following release from prison

  • re-arrest

    Re-arrest will be assessed using self-report on the Arrests and Days Incarcerated form and from Official Records received from the Maryland Department of Public Safety and Correctional Services

    12-months following release from prison

  • re-incarceration

    Re-incarceration will be assessed using self-report on the Arrests and Days Incarcerated form and from Official Records received from the Maryland Department of Public Safety and Correctional Services

    12-months following release from prison

  • criminal activity

    Self-reported crime days will be defined as continuous counts of days collected from the Addiction Severity Index and Time Line Follow-Back

    1,2,3,4,5,6,7 and 12-months following release from prison

  • Injection drug use and HIV sexual risk factors

    Injection drug use and HIV sexual risk factors will be measured using the Risk Assessment Battery.

    6 and 12-months following release from prison

Secondary Outcomes (1)

  • Treatment Group Equilibration

    6 and 12-months following release from prison
