GSK Drug Single Dose Escalation And Their Effect On Resting Motor Threshold In Healthy Volunteers...
Bipolar DisorderThis is a First Time in Human Study to assess the safety, tolerability, pharmacokinetics and resting motor threshold (rMT) of single doses of GSK drug in healthy volunteers.This will be a 2 part and 2 centre study.Part 1 will be a double-blind, randomized, placebo-controlled, single oral dose, dose-rising, cross-over study in healthy male and female (of non-child bearing potential) volunteers.Subjects will be randomized into cohorts of 10 subjects and cohorts will be recruited until the pre-defined safety or PK stopping limits are reached.Each subject will receive placebo and no more than 4 ascending doses of GSK drug in a randomized sequence on 5 separate study occasions.Each dosing session will take place over 2 days and there will be at least one subject on placebo on each day. There will be only one subject on any new active dose during the first day.Part 2 will be a randomised, double-blind, double-dummy, placebo-controlled, cross-over study to investigate the effect of single doses of GSK drug and lamotrigine on resting motor threshold in healthy male subjects. Subjects will attend the unit a maximum of 4 separate occasions.During each session subjects will receive up to 4 TMS measurements and single doses of either GSK drug, lamotrigine or placebo, in a randomised manner.Up to two doses of GSK drug will be investigated.
rTMS in the Treatment of Bipolar Depression
Bipolar Affective DisorderBipolar affective disorder (BPAD) is: A serious mental illness Estimated to be present in as high as 6.4% of the population in Western populations Associated with considerable disability and high morbidity. Characterized by periods of both lowered and elevated mood (i.e. depression and mania/hypomania respectively). The depressive aspect of bipolar disorder is often overlooked, possibly due to its less dramatic nature, despite its significant impact on the lives of those affected. Bipolar depression (BPAD-DP) is associated with a twenty fold increased risk of suicide, and typically lasts three to five times as long as a manic or hypomanic episode. Despite this, there has been relatively sparse investigation of treatments for BPAD-DP, with guidelines based primarily on expert judgment rather than clinical trials. In addition a significant proportion of patients with bipolar depression do not respond to the range of commonly used medications. One of the only substantially new treatments developed for unipolar depression in recent years has been the advent of repetitive transcranial magnetic stimulation (rTMS). Repetitive TMS has been evaluated in over 20 trials conducted over the last ten years, but no substantive trials have explored its use in bipolar depression. We propose to do this, conducting a large scale clinical trial. The trial will include the assessment of both high frequency left sided rTMS (as there is clearly the greatest evidence for the effectiveness of this in unipolar depression) and low frequency right sided rTMS (as this there is growing evidence of the effectiveness of this in unipolar depression and we have an excellent pilot study to suggest its potential in BPAD-DP and it has never previously been assessed in a clinical trial exclusively targeting this patient group). Our previous research strongly supports the effectiveness of rTMS paradigms including low frequency right-sided stimulation in unipolar depression and suggests these may have value in BPAD-DP. As BPAD-DP is clearly a clinical problem of significant impact and with limited treatment options, there is a pressing need for the development and definitive testing of novel treatments such as rTMS.
A Pilot Study of Citicoline add-on Therapy in Patients With Bipolar Disorder or Major Depressive...
Amphetamine AbuseAmphetamine Dependence2 moreBipolar disorder (BD) is a common and severe psychiatric illness. Drug and alcohol abuse are very common in people with BD and other mood disorders and are associated with increased rates of hospitalization, violence towards self and others, medication non-adherence and cognitive impairment. However, few studies have investigated the treatment of dual-diagnosis patients as substance use is frequently an exclusion criterion in clinical trials of patients with BD. To address this need, we have developed a research program that explores the pharmacotherapy of people with BD and substance related-disorders. A potentially very interesting treatment for BD is citicoline. Some data suggest that this supplement may stabilize mood, decrease drug use and craving, and improve memory. We found promising results with citicoline in patients with BD and cocaine dependence. In recent years the use of amphetamine and methamphetamine has become an important public health concern. However, virtually no research has been conducted on the treatment of amphetamine abuse. We propose a double-blind placebo controlled prospective trial of citicoline in a group of 60 depressed outpatients with bipolar disorder, depressed phase or major depressive disorder and amphetamine abuse/dependence, to explore the safety and tolerability of citicoline, and its efficacy for mood symptoms, stimulant use and craving and its impact on cognition. Our goal is to determine which symptoms (e.g. mood, cognition, substance use) citicoline appears to be most effective and estimate effect sizes for future work.
A Study of Aripiprazole (Abilify) in Patients With Bipolar Mania
Bipolar DisorderThe purpose of this clinical research study is to learn if outpatients with bipolar mania who are partially nonresponsive to lithium or valproate monotherapy can achieve stable symptoms on a combination treatment of aripiprazole plus lithium or valproate.
Study of Quetiapine Monotherapy in Ambulatory Bipolar Spectrum Disorder With Moderate-to-Severe...
Bipolar DisorderThe purpose of this research study is to evaluate the safety, tolerability, and efficacy of quetiapine compared to placebo (sugar pill without medication) in the treatment of bipolar disorder with moderate to severe hypomania or mild mania. Quetiapine is approved by the United States Food and Drug Administration (FDA) for the treatment of schizophrenia and bipolar mania.
Efficacy and Safety of Quetiapine Compared With Valproate in the Treatment of Patients With Bipolar...
Bipolar DisorderThe purpose of the study is to evaluate the efficacy of quetiapine compared to valproate during a 12 month treatment period in subjects with Bipolar Disorder I or II with Rapid Cycling.
Quetiapine (Seroquel) Maintenance Treatment in Early Onset Bipolar Spectrum Disorders
Bipolar DisorderThis is a single center, open prospective study to evaluate the effectiveness of quetiapine monotherapy in the maintenance treatment of adolescent patients with a bipolar spectrum disorder (bipolar I and bipolar II disorders, cyclothymia, and bipolar disorder not otherwise specified [bipolar NOS]) for a minimum of 48 weeks. Patients will be screened (enrolment phase) either when already stabilized or during an acute episode of mania/hypomania or depression.
A Study of the Effectiveness and Safety of Risperidone as add-on Therapy to Mood Stabilizers in...
Bipolar DisordersManic DisorderThe purpose of the study is to evaluate the effectiveness and safety of risperidone (an antipsychotic medication) versus placebo as add-on therapy to mood stabilizers in the treatment of manic episodes associated with bipolar disorder.

Bipolar DisorderThe purpose of this study is to assess the efficacy and safety of adding topiramate as compared to placebo to the medications a patient with bipolar disorder is already taking (lithium or valproate) to see if adding topiramate will better control the patient's manic symptoms.
A Study to Evaluate the Efficacy and Safety of Adjustable Doses of Extended-release (ER) Paliperidone...
Affective PsychosisBipolar2 moreThe purpose of this study is to evaluate the effectiveness and safety over a 6-week period of paliperidone ER compared with placebo in treating subjects with Bipolar I Disorder who are experiencing a manic or mixed episode while they are taking lithium or valproate. This study will also evaluate the effect of paliperidone ER compared with placebo on overall functioning, on how quickly a response is seen, on improvement in severity of illness, on health-related functional status, on depressive symptoms, and on psychotic symptoms. The relationship between blood levels and the effectiveness and safety of paliperidone ER will be evaluated, including the effect of food relative to time of taking the drug.
