Active clinical trials for "Schizophrenia"

The purposes of this study are to evaluate the dose proportionality of 1.5- and 3 mg tablets of paliperidone ER, to document the pharmacokinetics of a 1.5 mg dose of paliperidone ER, and to assess the safety and tolerability of the 1.5- and 3 mg tablets in healthy men.

The purpose of this study is 1) to investigate the single-dose pharmacokinetics of immediate release (IR) paliperidone, after oral administration, in patients having moderate hepatic impairment compared to patients having normal hepatic function, 2) to document the plasma protein binding and disposition of the enantiomers of paliperidone, and 3) to evaluate the tolerability and safety profile of IR paliperidone in both patient populations.

The purpose of this clinical trial is to find out how effective low dose oral naltrexone is on reducing body weight when compared to placebo in women with schizophrenia and schizoaffective disorder.

The objective of this study is to explore the efficacy, safety and cognitive properties of Lu AE58054 as augmentation therapy to risperidone in patients with schizophrenia.

The primary objective of this study is to evaluate the efficacy of quetiapine fumarate extended-release (XR) used as mono-therapy, administered once daily, in the treatment of schizophrenic patient with acute episode.

The objective of the study is to evaluate the efficacy of allopurinol, compared to placebo, as add-on to anti-psychotics in the treatment of patients with schizophrenia.

The purpose of this study is to determine whether augmenting work services with cognitive remediation can improve vocational outcomes for psychiatrically disabled participants in VA work services.

The purposes of this study are to characterize the pharmacokinetics of paliperidone after single- and multiple-dose administration of paliperidone ER in children and adolescent patients (>= 10 to <= 17 years of age) with schizophrenia, schizoaffective disorder, or schizophreniform disorder and to evaluate the safety and tolerability of paliperidone ER in this patient population.

The purpose of this study is to characterize the pharmacokinetics of paliperidone in plasma and urine after intravenous (i.v.) administration of the racemate, administration of the immediate-release (IR) racemate oral solution, administration of the ER OROS tablet, and administration of the oral solutions of the individual enantiomers R078543 (+) and R078544 (-); to determine the absolute oral bioavailability of IR and ER OROS paliperidone; to document the (+) and (-) paliperidone enantiomer ratio after i.v. and oral administration (IR and ER OROS paliperidone); to document the possible interconversion between the (+) and (-) enantiomers of paliperidone after oral treatment with the separate enantiomers; to document the possible relationship between the subject's CYP2D6 phenotype and the (+) and (-) enantiomer disposition of paliperidone (CYP2D6 genotyping was used to corroborate the phenotype). In addition, the safety and tolerability of all treatments will be evaluated.

The purpose of this study is to evaluate the dose proportionality of the 3-, 6-, 9-, 12-, and 15-mg tablets of ER OROS paliperidone. Additionally, the safety and tolerability of the treatments in healthy volunteers will be assessed.
