Varenicline is a drug that changes levels of certain brain chemicals that may also be useful in helping people to stop using methamphetamine. Our goal is to determine the safety and effects of varenicline (1 and 2 mg, daily, vs. a placebo) when it is used before experimental administration of methamphetamine, on a number of physical and psychological measures; specifically blood pressure, heart rate, and how you feel after taking methamphetamine. The secondary purpose is to determine the effects of treatment with varenicline (1 and 2 mg daily), compared to treatment with placebo, on the reinforcing effects of methamphetamine by measuring methamphetamine self-administration in methamphetamine-dependent human volunteers.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\nIn order to participate in the study, participants must:\n\n1. Be English-speaking volunteers who are not seeking treatment at the time of the study\n2. Be between 18-55 years of age\n3. Meet DSM-IV TR criteria for MA dependence\n4. Must be cigarette smokers, defined as smoking 10 or more cigarettes per day by self-report\n5. Have a self-reported history of using MA by the smoked or IV route and provide at least one MA-positive urine prior to admission\n6. Have vital signs as follows: resting pulse between 50 and 90 bpm, blood pressures between 105-150 mm Hg systolic and 45-90 mm Hg diastolic; this criterion must be met within 2 days of admission\n7. Have hematology and chemistry laboratory tests that are within normal (+/- 10%) limits with the following exceptions: a) liver function tests (total bilirubin, ALT, AST, and alkaline phosphatase) \\< 3 x the upper limit of normal, and b) kidney function tests (creatinine and BUN) \\< 2 x the upper limit of normal\n8. Have a baseline EKG that demonstrates normal sinus rhythm, normal conduction (including QTc), and no clinically significant arrhythmias\n9. Have a medical history and brief physical examination demonstrating no clinically significant contraindications for study participation, in the judgment of the admitting physician or nurse practitioner and the principal investigator.\n\nExclusion Criteria:\n\nSubjects will be excluded if they:\n\n1. Have any previous medically adverse reaction to METH, including loss of consciousness, chest pain, or epileptic seizure\n2. Have neurological or psychiatric disorders, as assessed by MINI, such as: episode of major depression within the past 2 years; lifetime history of schizophrenia, other psychotic illness, or bipolar illness; current organic brain disease or dementia assessed by clinical interview; history of or any current psychiatric disorder which would require ongoing treatment or which would make study compliance difficult; history of suicide attempts within the past three months and/or current suicidal ideation/plan; history of psychosis occurring in the absence of current METH use\n3. Meet DSM-IV criteria for abuse/dependence on alcohol or other drugs, except nicotine or marijuana\n4. Have used methamphetamine only by the intravenous route\n5. Have evidence of clinically significant heart disease or hypertension, as determined by physician\n6. Have evidence of untreated or unstable medical illness including: neuroendocrine, autoimmune, renal, hepatic, or active infectious disease\n7. Have HIV and currently symptomatic, have a diagnosis of AIDS, or currently taking antiretroviral medication\n8. Be pregnant or nursing. Other females must either be unable to conceive (i.e., surgically sterilized, sterile, or post-menopausal) or be using a reliable form of contraception (e.g., abstinence, birth control pills, intrauterine device, condoms, or spermicide). All females must provide negative pregnancy urine tests before study entry, and throughout the study\n9. Have any history of asthma, chronic coughing and wheezing, or other chronic respiratory illnesses\n10. Currently use alpha or beta agonists, theophylline, or other sympathomimetics\n11. Have made a suicide attempt in the past year\n12. Have any other illness, condition, or use of medications, which in the opinion of the PI and/or the admitting physician would preclude safe and/or successful completion of study.\n\nCriteria for Discontinuation Following Initiation:\n\n1. Positive urine drug screen or breath test indicating illicit use of cocaine, MA, alcohol, opiates, or other abused drugs not delivered as part of this protocol\n2. Inability to comply with study procedures\n3. Meet discontinuation criteria due to exaggerated response to MA, described below\n4. Nausea severe enough to require treatment.\n\nRationale for Subject Selection Criteria:\n\nParticipants are required to have used MA by the smoked or IV route to avoid exposing participants to routes of administration that produce more intensive interoceptive effects. The age criteria were selected primarily to avoid enrolling participants with undiagnosed cardiovascular disease. Participants with active HIV disease are excluded to avoid potential exacerbation of their underlying disease; participants with asymptomatic HIV are included because this group is at high risk for MA dependence. Participants with asthma (or who take asthma medications) are excluded due to potential adverse interactions between beta agonist medications and MA.'}, 'identificationModule': {'nctId': 'NCT01571167', 'acronym': 'Varenicline', 'briefTitle': 'Varenicline as a Treatment for Methamphetamine Dependence', 'organization': {'class': 'OTHER', 'fullName': 'Baylor College of Medicine'}, 'officialTitle': 'A Human Laboratory Assessment of the Safety and Potential Efficacy of Varenicline in Methamphetamine-Dependent Volunteers Receiving Methamphetamine', 'orgStudyIdInfo': {'id': 'H-26875'}, 'secondaryIdInfos': [{'id': 'DPMC', 'type': 'OTHER', 'domain': 'NIDA'}, {'id': '1R01DA027134-01', 'link': 'https://reporter.nih.gov/quickSearch/1R01DA027134-01', 'type': 'NIH'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'interventionNames': ['Drug: Placebo']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Varenicline 2 mg', 'interventionNames': ['Drug: Varenicline']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Varenicline 1 mg', 'interventionNames': ['Drug: Varenicline']}], 'interventions': [{'name': 'Placebo', 'type': 'DRUG', 'otherNames': ['Sugar pill'], 'description': 'Participants will receive varenicline or matched placebo from day 1 through day 7, then the same subjects will return within 2-4 weeks and assigned to each of the two remaining study medication conditions, and undergo the identical procedures (3-phase study).', 'armGroupLabels': ['Placebo']}, {'name': 'Varenicline', 'type': 'DRUG', 'otherNames': ['Chantix'], 'description': 'For varenicline 1 mg, dosing will begin at 0.5 mg once daily (with 0 mg placebo to maintain blind of bid dosing) for days 1-3, will be increased to 0.5 mg twice daily for the days 4-6, and then reduced to 0.5 mg once daily on day 7.
