Filter by:The purpose of this study is to examine the long-term economic, functional and clinical outcomes in schizophrenia patients who require a change in antipsychotic treatment, and are changed to either paliperidone extended release (ER) or another oral atypical antipsychotic agent (AAP) including aripiprazole, olanzapine, quetiapine, risperidone, or ziprasidone.
The purpose of this study is to compare the efficacy of quetiapine IR, following rapid titration versus conventional titration in patients with acute psychosis
The purpose of this study is to determine whether increasing the amount (dose) of quetiapine IR (immediate release formulation) more rapidly than conventional dose increases, improves the control of symptoms as measured by the Positive and Negative Syndrome Scale (PANSS) - a psychiatric assessment scale that measures both positive and negative symptoms - in patients with acute schizophrenia or schizoaffective disorder.
AVE1625 is a new potent and selective cannabinoid 1 (CB1) antagonist in clinical development for the treatment of cognitive impairment in patients diagnosed with schizophrenia. The main objective of this study is to evaluate the efficacy on cognitive impairment of 3 doses of AVE1625 using a new cognitive battery called MATRICS (Measurement and Treatment Research to Improve Cognition in Schizophrenia) in schizophrenic patients. The secondary objectives are to measure the efficacy of AVE1625 on functional capacity of the patients using a specific scale called UPSA2 (University of California San Diego Performance-based Skills Assessment 2) and to assess the safety of the compound.
The study aims to investigate the modulation of regional brain activation in schizophrenic patients by psychopharmacological treatment with either haloperidol, amisulpride or olanzapine. The study will be performed with functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI).
The purpose of this study is to compare the efficacy and tolerability of zotepine versus Risperidone in aggressive schizophrenic patients.
The objective of this study is to explore the safety and efficacy of ABT-925 involving patients who meet the DSM-IV-TR (Diagnostic and Statistical Manual of Medical Disorders, Fourth Edition Text Revision) criteria for an acute exacerbation of schizophrenia or schizoaffective disorder.
The primary objective of the study is to evaluate changes in weight short and long term with bifeprunox and quetiapine. Study participation for the subject is 57 weeks.
The purpose of this study is to determine the effect of bifeprunox or risperidone on the body weight of patients with schizophrenia.
An open-label extension study using a variable dose (20 to 30 mg daily) of bifeprunox to evaluate long-term safety.
