Study summary

This is a double-blind, placebo-controlled, randomized clinical trial evaluating the efficacy of extended-release naltrexone plus bupropion as a combination pharmacotherapy for methamphetamine use disorder. Participants will be randomly assigned to the active medication combination (AMC) group or matching placebo group and will receive medications over the course of 12 weeks. Follow-ups will occur in weeks 13 and 16.

Read the detailed description

There will be 400 adults with moderate or severe methamphetamine use disorder randomized into this multi-site study. Eligibility will be determined during a maximum 21 day screening period. After screening is completed and eligibility is confirmed, including successful administration of a naloxone challenge, participants will begin the 12 week medication phase of the trial. Participants will be randomized to either the 1) AMC arm and receive injections of extended release naltrexone (XR-NTX; as Vivitrol®) plus once-daily oral extended-release bupropion tablets (BUP-XL) or the 2) matching placebo (PLB) arm and receive injections of placebo (iPLB) plus once-daily oral placebo (oPLB) tablets. During the course of the study, participants may be switched to another arm, as determined by the a priori adaptive aspect of the study design. Participants appearing to respond well to their original treatment assignment will not be switched. Overall, approximately 50% of the participants will receive the AMC. Injections will be administered every three weeks, in weeks 1, 4, 7, and 10. Take-home oral study medication (BUP-XL or oPLB) will be dispensed weekly for dosing on non-clinic days. Participants will be asked to attend the clinic twice weekly for observed oral medication dosing, assessments, collection of urine samples, and once-weekly medical management. On non-clinic days, participants will participate in smartphone app-based medication adherence activities. Participants will be asked to complete assessments as indicated on the schedule of assessments. Following the 12 week medication phase, participants will complete a follow-up phase, including a medication taper and post-medication phase follow-up visits during weeks 13 and 16.

SecondaryMean Change of Overall Functioning as Measured by Treatment Effectiveness Assessment (TEA) at Stage 1

The Treatment Effectiveness Assessment is a 4-item self-administered assessment that uses a Likert scale (1-10) to document changes in four life domains: substance use, health, lifestyle, and community and is collected at screening, mid-treatment (Week 6 Visit 2) and end-of-treatment (Week 12 Visit 2). Possible scores range from 4-40, with higher scores indicating a higher overall functioning.
