NCT02111798

Brief Summary

This project will examine effects of bupropion extended release (XL) at a dose of 300mg/day for cocaine abstinence among persons receiving methadone for the treatment of opioid use disorder. Participants also earned financial incentives for providing urine samples that tested negative for cocaine. Bupropion was examined for this purpose because of its previously demonstrated efficacy and safety as well as its pharmacological actions at dopamine systems. Participants were randomly assigned to bupropion XL vs. placebo and received different incentive schedules depending on whether they demonstrated abstinence from cocaine early in the study. Outcomes were tracked over a 6-month time frame and the overarching hypothesis was that bupropion (as compared to placebo) would increase the number of urine samples testing negative for cocaine, independent of whether participants demonstrated abstinence from cocaine early in the study.

Outcome Measures

Primary Outcomes (1)

  • Number of Cocaine Negative Urines

    Comparison of the number of thrice-weekly urine tests submitted during weeks study 7-30 negative for cocaine for persons randomly assigned to receive placebo or bupropion XL during weeks 7-30; excused samples are omitted and missing samples are treated as positive.

    Weeks 7-30

Secondary Outcomes (1)

  • Longest Consecutive Period of Negative Urine Samples

    Weeks 7-30

Study Arms (4)

Placebo/Abstinence Initiation

PLACEBO COMPARATOR

In week 2 participants will randomly assigned to receive twice daily capsules filled with placebo powder. At the end of week 6, participants who did not provide \>/=3 consecutive negative urine samples during weeks 1-6 of the trial will be assigned to the Abstinence Initiation incentive arm.

Participants will provide urine samples thrice weekly during weeks 1-6 of the study. Urine samples will be tested immediately onsite for evidence of recent cocaine exposure. Participants who do not provide 3 urine samples that test negative for cocaine by the end of week 6 will be assigned to an Abstinence Incentive condition.
