Pharmacogenomics and Medication Development for Methamphetamine Dependence
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Currently there are no medications approved for the treatment of methamphetamine addiction. Bupropion is an antidepressant that is approved by the Food and Drug Administration (FDA) for the treatment of depression and for cigarette smoking cessation but is not approved by the FDA for the treatment of methamphetamine addiction. Preliminary research studies suggest that bupropion may help people receiving treatment for methamphetamine addiction to reduce or to stop their methamphetamine use. But results of these studies also suggest that bupropion may help certain groups of patients more than others, such as men versus women and light versus heavy methamphetamine users, although the reasons for this difference are not known. One possibility is that a person's genetic make up may influence whether or not they respond to treatment with bupropion for methamphetamine addiction. The purpose of the study is to determine if bupropion is can help people reduce or stop their methamphetamine use and to investigate whether genetic variations influence whether people respond to treatment with bupropion for methamphetamine addiction, which may help doctors and patients better decide if treatment with bupropion will be beneficial or not. To identify possible genetic variations that influence response to bupropion, we will perform genetic tests on blood or saliva specimens from participants receiving treatment with either bupropion or placebo (which is a pill that contains no medication) in conjunction with standard cognitive behavioral therapy drug counseling. We will compare methamphetamine use, as assessed with urine drug screens, among participants receiving bupropion versus those receiving placebo to determine if bupropion helps people to reduce or stop their methamphetamine use. We will then compare the results of the genetic tests among participants who respond and who do not respond to bupropion. In addition, since the amount of methamphetamine a person uses was associated with response to bupropion in preliminary studies, we will also compare the results of genetic testing among persons with heavy versus light methamphetamine use before entering treatment. Results of this study have the potential to provide insights into the biology of methamphetamine addiction and help increase the understanding of how bupropion works. This information could be useful to develop effective medications for methamphetamine addiction and to improve the ability of clinicians to provide treatment to patients with methamphetamine addiction.
