About this study
Official title: Open-Label Pilot Study of Disulfiram for Methamphetamine Dependence
This 8 week, open-label pilot clinical trial will examine the safety and tolerability of disulfiram at 250 mg/day in up to fifteen methamphetamine dependent individuals. After undergoing screening procedures (approximately one week), eligible subjects will enter the study proper attend clinic every weekday during week 1 of the trial in order to receive the disulfiram under observation and complete assessments. Then subjects will receive weekly blister packs of medication and attend clinic thrice weekly during weeks 2-6. During weeks 7-8, subjects no longer take disulfiram, are followed for two weeks, then referred to treatment elsewhere, if desired. Urine samples will be obtained and a disulfiram side-effects checklist will be completed thrice-weekly. Self-reported drug use, craving and mood ratings will be completed weekly. All subjects undergo cognitive behavioral therapy. Adjunctive contingency management procedures will be utilized to enhance retention. The primary outcomes of interest include retention, side-effects, and drug use. Our hypothesis is that disulfiram will be well tolerated in this population.

What is being measured
The primary outcome is the main question the study is designed to answer.
Side Effects Checklist
It consists of 25 items describing side effects specific to disulfiram alone or combined with alcohol or cocaine that are rated on a scale from 0 (not at all) to 4 (very much). Total scores range from 0 (minimum) to 100 (maximum). Data were entered into a mixed model ANOVA in order to determine whether scores significantly changed over time. A slope and standard deviation describing this change over time were generated and used as our outcome measures.
Measured: Weekly for six weeks
Secondary outcomes (1)
Proportion of Amphetamine-positive Urine Samples
the proportion of urine samples positive for amphetamine. Data were entered into a mixed model ANOVA in order to determine whether scores significantly changed over time. A slope and standard deviation describing this change over time were generated and used as our outcome measures.
Measured: thrice weekly for 6 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Disulfiram in people with Methamphetamine Dependence, run by University of Arkansas at 1 site 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 5 inclusion and 7 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 27 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Yes. Results are posted in the registry (first posted 27 Feb 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Side Effects Checklist (time frame: Weekly for six weeks). 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 27 Feb 2012.
