Filter by:This is an open-label, single center study of The Bridge in patients with sustained remission of opiate dependence on established, low-dose MAT with buprenorphine. A fixed number of patients will be admitted to the study.
This is a placebo-controlled study intended to examine the effects of the neutraceutical citicholine, together with omega-3 fatty acids, on a range of measures in individuals with concussive head injury, often referred to as traumatic brain injury, or TBI. The study will consist of three visits, during which participants will complete brain scans, a thorough testing battery and a clinical interview to assess mood and other diagnostic information relevant to the study.
This project focuses on the under-researched group of individuals who develop psychotic episodes of short duration (less than four weeks) while using substances. This includes individuals diagnosed with psychotic disorder not otherwise specified (PNOS) or substance-induced psychotic disorder (SIP) AND substance abuse or dependence. Very little is known about the most appropriate maintenance/relapse prevention management of these subjects. These individuals are not diagnosed with a primary psychosis because psychotic symptoms are too short-lived or non-specific, the onset of substance use precedes the onset of psychotic symptoms and the subject has not experienced sufficient psychotic symptoms in the absence of substance use. However, previous studies have shown that they are at high risk of recurrence of psychotic symptoms. Thus, this project will assess the efficacy of the second-generation antipsychotic aripiprazole for maintenance treatment of subjects who had a recent psychotic episode of short duration associated with substance use. The investigators will compare aripiprazole and placebo for preventing the recurrence of psychotic symptoms and decreasing substance use during a 6-month maintenance phase.
This study will compare the effects of GSK598809 and placebo in alcohol dependent volunteers. A placebo is a pill with no drug in it (i.e. dummy drug) but it is made to look exactly like the real drug. Subjects will be given one dose of GSK598809 during one visit and placebo during the other visit. These dosing visits will be at least 1 week apart. The study is randomised, which means that a computer programme will decide by chance (like tossing a coin), the order in which subjects will receive GSK598809 or the placebo, or in other words, whether they will receive GSK598809 or placebo first. The study is blinded, which means the subjects will not know whether they are receiving study drug or placebo first and neither will the doctors at the institute. If necessary for reasons of safety, the study staff can find out exactly what the subject has received. The study will last for approximately 4 weeks but could be up to 6 weeks, depending on length of time between screening and dosing. From screening the subjects will be alcohol-abstinent, they may be put on medication for treatment of withdrawal symptoms and then will have at least 7 days without any medication before beginning the study medication. During the study the subjects will be inpatients at the Central Institute of Mental Health. All subjects will be required to fill out questionnaires, perform behavioural tasks and undergo MRI and functional MRI (fMRI) scans.
The purpose of this study is to determine the effect of GSK598809 as compared to placebo in preventing recently-quit smokers from going back to smoking.
