Official title
A Randomized, Double-Blind, Placebo-Controlled Evaluation of Modafinil vs Placebo for the Treatment of Methamphetamine Dependence
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Modafinil is a non-amphetamine type stimulant that acts as a wakefulness-promoting drug, and is approved for managing symptoms of narcolepsy (i.e., daytime somnolence). Its precise mechanism of action in promoting wakefulness remains unclear. This trial is a placebo-controlled double-blind trial of modafinil, on a platform of contingency management (CM) and individual cognitive-behavioral (CBT) counseling, for the treatment of methamphetamine dependence. Participants in this study will complete a 2-week baseline screening period during which they will provide urine samples and complete physical and psychological assessments to establish their eligibility for the study. In addition, participants will be asked to provide a blood or saliva specimen for genetic testing in order to identify genetic variations that influence response to methamphetamine and to treatment with modafinil. Upon successful completion of screening, participants will be randomly assigned to receive either modafinil (400mg qd) or placebo during the 12 weeks of the study. Neither the participants nor study staff will know who is receiving active medication or placebo. Regardless of medication condition, all participants will receive CM and weekly individual CBT counseling sessions to help them stop using methamphetamine and prevent relapse. They will attend the clinical research site (either at the UCLA Hollywood Clinic, or the Rancho Cucamonga site) three times per week, providing urine samples at each visit, completing data measures, and receiving individual CBT counseling on one visit each week. At the end of the 12-week study, the medication or placebo will be discontinued. Participants will return to the research site approximately 30 days following medication discontinuation for a brief health check to assess any possible lingering side effects and complete brief data measures.
