XOR: Extended-Release Naltrexone Opioid Treatment at Jail Re-Entry
Study Details
Study Description
Brief Summary
The purpose of this study is to compare the effectiveness of extended-release naltrexone (XR-NTX) vs. enhanced treatment-as-usual (TAU) among opioid dependent adults leaving NYC jails. In parallel, we propose to recruit a matched, quasi-experimental methadone cohort, which will result in a naturalistic comparison of XR-NTX vs. an established jail-based methadone treatment program standard-of-care. Our primary aim is to compare time-to-relapse among participants treated with XR-NTX vs. randomized TAU controls and time-to-relapse among XR-NTX arm vs. jail-based MTP participants, following release from jail. Secondary aims will compare related opioid treatment outcomes post-release across all arms.

Detailed Description
This study is a randomized control trial of XR-NTX (n=85) vs. enhanced TAU (n=85) among opioid dependent adults leaving NYC jails who explicitly reject agonist treatment. Initiating treatment the week prior to release and continuing for 24 weeks post-release, we hypothesize the XR-NTX arm will demonstrate significantly longer time-to-relapse vs. TAU. In parallel, we propose to recruit a matched, quasi-experimental methadone cohort (n=85), which will result in a naturalistic comparison of XR-NTX vs. an established jail-based MTP standard-of-care.
Rationale: Immediate relapse to drug, alcohol, and tobacco use is a nearly universal and expected near-term outcome among adults with addiction disorders leaving U.S. jails. Yet while opioid agonist therapies are proven and effective re-entry interventions, many US correctional facilities, including almost all large U.S. municipal jails, do not offer these treatments. However, in New York City (NYC), jail-to-community methadone treatment is, since 1986, a well-studied standard-of-care, yet many inmates eligible to initiate the methadone treatment program (MTP) while incarcerated do not, possibly due to anti-methadone patient preferences. Rather, the vast majority of these jail detainees undergo a brief 6-day methadone taper following arrest, remain in jail for brief periods out-of-treatment while 'drug free' and undergoing a decline in physiologic opioid tolerance, nearly universally relapse to heroin or other illicit opioid use following release, and are re-arrested in the next 12 months at rates of 50-75%. Extended-release naltrexone (XR-NTX, Vivitrol), now FDA-approved for opioid dependence, produces a 30-day mu opioid receptor antagonist blockade, and offers an potentially promising modality for 'inoculating' persons leaving jails against immediate opioid relapse. Persons injected with 380mg of XR-NTX are unable to effectively experience euphoria or respiratory depression when returning to average doses of illicit opioids for the ensuing 4-5 weeks. An injection prior to release would possibly give the individual a month or so to return home from jail, experience opioid abstinence, and then either continue XR-NTX, initiate agonist or behavioral treatments, or, resume a significantly postponed relapse to illicit use. Our team recently established the feasibility of administering XR-NTX to opioid dependent adults within a week of release in NYC jails. We now propose to conduct a large, definitive randomized controlled trial estimating the effectiveness of XR-NTX as opioid treatment at release from jail vs. a counseling- and referral-enhanced treatment-as-usual (TAU) condition. We also propose to recruit a non-randomized, quasi-experimental cohort of participants in a jail-based methadone maintenance program (MTP), allowing an additional comparison of XR-NTX to a methadone standard-of-care.
Specific Aim 1: Randomized Effectiveness Trial of XR-NTX vs. TAU for Jail-to-Community Re-Entry Opioid Relapse Prevention. Our primary aim is to compare time-to-relapse among participants treated with XR-NTX vs. randomized TAU controls, following release from jail.
Specific Aim 2: Quasi-Experimental Comparison of XR-NTX vs. a Methadone Treatment Program for Re-Entry Opioid Relapse Prevention. To compare time-to-relapse among the XR-NTX RCT arm vs. jail-based MTP participants using a quasi-experimental design.
Specific Aim 3a-e: Related Opioid Treatment Outcomes. To compare re-entry rates of 5 treatment outcomes across all arms: 3a) community treatment initiation and retention, 3b) any opioid and other illicit drug or alcohol use, defined as continuous counts of both days, amount/day, and urine toxicologies, 3c) injection drug use and HIV sexual risk factors, 3d) accidental drug overdose and mortality, and, 3e) rates of re-incarceration and an exploratory analysis of cost-effectiveness.
Implications: While there is growing interest in the newly approve use of XR-NTX for opioid treatment, its effectiveness has not been evaluated in any correctional facilities, including large municipal jails, vs. usual care, nor in the context of standard-of-care methadone treatment. This study will allow providers, correctional and public health authorities, including our collaborators at the NYC Department of Health and Mental Hygiene, and payers and policy makers to assess the utility of XR-NTX as re-entry opioid treatment, with important implications for limiting the great public safety and societal costs of heroin and prescription opioid addictions. Further, NYC jail inmates are predominantly African American and Hispanic, and represent communities disproportionately affected by unemployment, family poverty, HIV and hepatitis C, all downstream effects of opioid dependence. As the majority of opioid addicted persons leave jail return to their neighborhoods untreated and prone to rapid relapse, we hypothesize adding XR-NTX to the re-entry 'toolbox' will save both money and lives in these under-served communities.
This study is part of the NIDA "Studies of Medication for Addiction Treatment in Correctional Settings (SOMATICS)" U01 Collaborative. Our distinct NIH-funded study at NYU has been aligned with two other jail-based opioid treatment studies conducted by researchers at Friends Research Institute (FRI) in Baltimore, MD, and at UCLA. SOMATICS seeks to harmonize assessments and interventions across the three research centers (RCs) and the three independent studies in order to leverage power, sample size, and increase the generalizability of findings. Each of the RCs in the SOMATICS cooperative will conduct their own individual trial, sharing one study arm with another RC, and several core assessments across all sites. The SOMATICS collaborative will have a common Statistical Analysis Plan and DSMP including a single DSMB. The collaborative primary and secondary outcomes across all sites are listed below:
Collaborative Primary Outcome Measures:
- DSM-5 Opioid Use Disorder Diagnosis during the 30 days prior to the 6 months post-release follow-up assessment: Measured by: DSM-5 checklist via a modified CIDI-2 Substance Abuse Module.
