Registered outcomes2

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryRelapse to Opioid Use in Subjects by Month 312 weeks (month 3)
Proportion (count) without relapse by month 3 post release. At each monthly assessment we determined whether a subject relapsed based on the timeline follow-back (TLFB) and/or urine drug screen results (UDS) and self-reported withdrawal.
SecondaryReincarceration0 to 28 monthspercentage of patients who were reincarcerated

Outcomes2

Each outcome the trial posted results for, in ClinicalTrials.gov's words.

TypeOutcomeTime framePopulationUnitsMeasured as
PRIMARYRelapse to Opioid Use in Subjects by Month 312 weeks (month 3)
In treatment arm 1 (before reentry) 38 subjects received vivitrol before leaving prison.~In treatment arm 2 (after reentry) 48 subjects were eligible to receive injections after release from prison. Arm 2 subjects were to return to the research clinic within 7 days after release to receive their first injection.
ParticipantsCOUNT_OF_PARTICIPANTS
SECONDARYReincarceration0 to 28 months
This outcome was determined as follows: one XR-NTX injection provided 4 weeks of treatment. Study patients also had counseling, thus weeks in treatment equaled the weeks of protected time from XR-NTX plus the number of weeks a patient had one or more counseling appointments after the protection from the last XR-NTX dose ended.
