Active clinical trials for "Schizophrenia"

The purpose of this study is to evaluate the pharmacokinetics of a single oral dose of 3 mg extended release paliperidone (ER OROSÃ' paliperidone) in patients with varying degrees of renal impairment (mild, moderate, and severe), compared to patients with normal renal function. Secondary objectives include the assessing the disposition of the (+) and (-) enantiomers by means of an enantioselective liquid chromatography mass spectrometry assay, to determine plasma protein binding of the enantiomers in patients with impaired renal function, compared with patients with normal renal function, and to evaluate the tolerability and safety profile of ER OROS paliperidone in patients with varying degrees of renal impairment (mild, moderate, and severe) compared with patients with normal renal function.

The purpose of this study is to 1) determine whether the effect on QT interval corrected (QTcLD) for heart rate using the population specified linear derived method at steady state is comparable between 12 mg paliperidone extended-release (ER) once daily and that of 400-mg quetiapine administered twice daily, 2) to explore the relationship between the pharmacokinetics of paliperidone ER and electrocardiogram (ECG) parameters of interest, 3) to explore the cardiovascular safety and tolerability of 18 mg paliperidone ER at steady state, and 4) to evaluate the safety and tolerability of all treatments.

The purpose of this study is to compare the steady-state pharmacokinetics of paliperidone after oral administration of 15 mg extended-release (ER) OROS paliperidone once daily with the steady-state pharmacokinetics of paliperidone after oral administration of 8 mg immediate-release (IR) risperidone twice daily; and to explore the dose-proportionality of 9 mg and 15 mg ER OROS paliperidone. Other objectives are to 1) document the disposition of the enantiomers of paliperidone; 2) explore the relationship between genotype (CYP2D6, CYP3A4, CYP3A5, UGT1A1, and UGT1A6) and pharmacokinetic parameters; and 3) assess safety and tolerability.

The purpose of this study is to evaluate the pharmacokinetics of 2 extended-release (ER) formulations of 2 mg-eq paliperidone in comparison to the 2 mg immediate-release (IR) paliperidone oral solution and to evaluate the effect of food on the pharmacokinetics of these ER formulations. Additional objectives are to compare the pharmacodynamic effects (postural changes in blood pressure and heart rate), safety, and tolerability are to be evaluated in addition to exploring the relationship between CYP2D6 and CYP3A4/5genotype and paliperidone exposure.

The main purpose with the study is to explore the efficacy and safety of Lu 31-130 in patients suffering from schizophrenia compared to a standard antipsychotic drug.

This is a four week open label trial of ALLOPURINOL to the treatment regime of ten (10) poorly responsive patients with schizophrenia, monitoring their response and side-effects. No change in medication is required.

In a randomized clinical trial, the researchers want to investigate if the positive short-term outcomes (first 1-2 years), achieved with specialized assertive intervention programme (OPUS), can be maintained for five years if the specialized treatment is sustained over the first five years in comparison to only two years of specialized treatment followed by three years of standard treatment.

Schizophrenia is associated with significant cognitive and functional deficits. As patients with schizophrenia grow older, the impact of these deficits at a personal and public health level is likely to increase. Cognitive Behavioral and Social Skills Training (CBSST) is a recently developed group therapy that increased the frequency of social activities among middle-aged patients with schizophrenia. It also increased cognitive insight, a measure of the ability to reduce confidence in aberrant beliefs. To date, CBSST has not been studied in late-life schizophrenia. In addition, its impact on medications management, an instrumental function that is particularly salient in late life, and its interactions with cognition are largely unknown. Thus, we propose to study the efficacy of CBSST in improving social skills and medications management in patients with late-life schizophrenia, and to study the interactions between the patients' cognitive characteristics and their response to CBSST. Previous studies show that cognitive deficits are strong predictors of response to CBSST. Cognitive Remediation Treatments (CRTs) have been shown to improve cognition in patients with schizophrenia especially when combined with psychosocial interventions that focus on function such as CBSST. Thus, we also propose to assess the tolerability and impact of CRT on patients with late-life schizophrenia.

This is a two part study designed to evaluate the safety and efficacy of SB-773812 in the treatment of acute schizophrenia. Subjects with acute schizophrenia will be randomized in an adaptive design study to receive placebo, SB-773812 60mg or olanzapine 15mg for 12 weeks in Part A. An interim analysis will be conducted to assess the efficacy and safety of the SB-773812 60mg dose compared with placebo. Based on these data, up to two further doses of SB-773812 will be added to the randomization for Part B.

This study is being carried out to see if quetiapine (Seroquel) is effective in preventing patients from a schizophrenic relapse when studied for a long time (1 year) and if so, how it compares with non-active treatment.
