Filter by:The primary objective of the study is to test the incremental efficacy and outcomes of an aftercare program of Cognitive Behavioral Therapy combined with motivational therapy (CBT-MT) relative to treatment as usual (TAU) in improving depression, substance use, and healthcare outcomes in a population with drug dependence and comorbid major depressive disorder (MDD). The investigators expect that among drug-dependent patients with comorbid MDD, CBT-MT will yield better clinical outcomes relative to TAU in reducing depressive symptoms and substance use and improving healthcare outcomes during treatment. Secondary Objectives: 1. Test efficacy and outcomes of CBT-MT and TAU 2. Evaluate the differential effect of CBT-MT versus TAU on HIV-risk behavior of participants, 3. To evaluate the impact of cognitive functioning on treatment retention and outcomes, and 4. To explore additional psychosocial, demographic, and diagnostic factors (e.g., age, gender, education level, motivation for change, social support) that may be associated with treatment outcome and retention in this high need population.
This study will develop and test a brief telephone-delivered motivational enhancement intervention for substance abusing military personnel who are not currently in treatment. The hypotheses being tested are that this intervention will prompt a willingness to participate voluntarily in a self-appraisal of substance abuse behavior and consequences, self-initiated change or enrollment in a treatment or self-help program, and cessation of abuse of alcohol or other drugs.
This novel compound is a new experimental treatment that may help people to stop compulsive overeating. Compulsive overeating or binge eating is one of the main reasons why people are overweight or obese. Recent research has shown that some kinds of overeating may be linked to a brain chemical called dopamine. There is some evidence that blocking the action of this chemical in animals can reduce food intake, particularly of foods that are high in fat and sugar. The purpose of this study is to find out if this compound (which blocks the effects of dopamine) has the same effect in overweight or obese people, as it does in animals.
The proposed study will evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics of repeated oral doses of GSK618334 in healthy male and female volunteers.
Purpose: This is an outpatient, randomized, double-blinded, placebo-controlled study in which either varenicline (twice daily) or placebo will be administered over a 12 week study period to examine genetic influences on treatment response to varenicline for reduction of hazardous drinking.
This study will investigate the possible effects of alcohol in combination with GSK598809 on the central nervous system in 20 healthy male and female volunteers, between 18 and 65 years of age. During 4 separate study periods subjects will receive the following treatment combinations: Alcohol + GSK598809, alcohol + placebo drug, placebo infusion + GSK598809, and placebo infusion + placebo drug. A placebo is a pill or liquid infusion which contains no drug or alcohol; it is a dummy version. Therefore it is administered in the same way that either the study drug or ethanol is depending on which placebo it is. All study drugs are administered in a random order and both the doctor and the participant are not aware of the treatment combination. However treatment combinations will be available at the end of the study or in case of an emergency. GSK598809 is administered orally and alcohol is administered per infusion. The duration of the infusion is 5 hours, during which approximately 75 grams of alcohol is infused, which is comparable to less than one bottle of wine.
The purpose of this study is to investigate the relationship between the plasma concentrations of the study drug and the amount of the study drug bound to the D3 receptors of the brain after dosing of a new compound GSK618334.
Study to compare PK of a new 100mg capsule with four 25mg capsules. This is required because we plan to have only single capsules administered in the later phase clinical trials but we have not had a 100mg strength before. As this is a new previously untested strength we need to ensure that the PK is similar to that achieved using 4 x 25mg. The study will also assess the effect of high fat food on the PK of the 100mg capsule. The study is planned to consist of a single part , with three dosing periods, periods 1-3 consisting of 16 subjects. There will be a week wash out between each dose. In the three dosing periods subjects will either received 4x25 mg GSK598809 capsule in a fasted state, 100mg capsule in a fasted state or 100mg GSK598809 capsule in a fed state. Subjects will return to the centre for follow-up 7-14 days after the final dose. It is expected that the total duration of the study should be approximately eight weeks.
Study to investigate the safety, tolerability and pharmacokinetics of GSK598809 in otherwise healthy volunteers. This study is required because this drug is being developed for the treatment of nicotine dependence. It is important to evaluate how this drug interacts in healthy smokers. The study is planned to consist of a single part, with 4 dosing periods. Subjects will receive 3 escalating doses of GSK598809 and 1 dose of placebo. There will be at least 1 week of wash out between doses. In each dosing period 14 subjects will receive escalating doses and 4 subjects will receive placebo. The actual doses used will be determined based on the safety/ tolerability and pharmacokinetics during the previous dose. It is expected that the duration of this study will be approximately 10 weeks.
The rapid scale up of opioid substitution treatment (OST) for drug users mainly achieved through the possibility of prescribing buprenorphine in primary care has been successful in reducing HIV prevalence among drug users but still inadequate for reducing the spread of HCV. To date, methadone in France can only be initialised in drug centres but GPs can prescribe methadone after stabilisation of dosages. This study was born as an answer to a request from the French Minister of Health that supports the initialisation of methadone in primary care in order to improve coverage by OST (now 70%) in drug users.
