Summary

Methamphetamine (MA) dependence is a source of continuing danger for both individuals and society. While there are some behavioral treatments, they are not always effective. To date, there are no medications available to treatment methamphetamine dependence. There is some early evidence suggesting that varenicline (also known as Chantix(tm)) may help people to stop or reduce their use of methamphetamine. Varenicline is already on the market in the U.S. for cigarette smoking cessation and shows promise for treating alcohol dependence. In order to determine if varenicline can help people stop using methamphetamine, we will enroll 90 methamphetamine-dependent people who are looking for treatment into the study at the UCLA Vine Street Clinic operated by Dr Shoptaw of UCLA. Half will receive varenicline (n=45) and half will receive placebo (n=45) which will be determined randomly. Everyone will receive talk therapy for methamphetamine dependence. People will take the medication for 9 weeks followed by a 4 week follow-up period. Before receiving any medication, participants will complete a maximum 2 week (6 study visits) lead-in to complete baseline assessments, psychological and medical evaluation, and comprehensive assessment of drug use to determine study eligibility. If a person is eligible for the study, s/he will receive either varenicline or placebo. Participants will visit the UCLA Vine Street Clinic (UCLA VSC) three times a week study visits. At the end of the medication phase, subjects will complete a four week follow up period for safety monitoring.
