About this study
Official title: A Randomized, Double-Blind, Placebo-Controlled Evaluation of Bupropion vs Placebo for the Treatment of Methamphetamine Dependence
Methamphetamine is an addictive stimulant drug that strongly activates certain parts of the brain. The purpose of this study is to determine the effectiveness of bupropion in combination with behavioral therapy for the treatment of methamphetamine addiction.
Read the detailed description
Methamphetamine is a drug that causes excess amounts of the neurotransmitters dopamine and norepinephrine to be released into the brain. This overload produces unusual alertness and feelings of elation. When the body undergoes methamphetamine withdrawal, it experiences a reduction in dopamine and norepinephrine. Bupropion is an antidepressant used for the treatment of depression and smoking cessation. Because it functions by increasing the release of dopamine and norepinephrine in the brain, bupropion is likely to decrease the negative effects of methamphetamine withdrawal. The purpose of this study is to evaluate the efficacy of bupropion combined with contingency management (CM) and cognitive behavioral counseling (CBT) as a means of treating methamphetamine dependence.
An initial 2-week screening process will involve participants providing urine samples and completing physical and psychological assessments. If deemed eligible for the remainder of this double-blind study, participants will be randomly assigned to receive either bupropion or placebo over the course of 12 weeks. Participants in both the bupropion and placebo groups will receive contingency management and cognitive behavioral counseling. Participants will report to one of two clinical research sites three times per week. At each visit, participants will be examined by the study staff, provide a urine sample, and receive individual cognitive behavioral counseling sessions. At the end of 12 weeks, treatment will be stopped. Participants will return to the study site 30 days later for evaluation and to be assessed for any possible lingering side effects.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Bupropion in people with Methamphetamine, run by National Institute on Drug Abuse (NIDA) at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Addiction severity, Week 16. The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jan 2017.
