NCT00216281
This is a randomized, placebo-controlled study to assess the efficacy and safety of ATX augmentation of CLZ as a treatment for the cognitive symptoms of schizophrenia. A total sample size of 126 subjects diagnosed with schizophrenia and being treated with the antipsychotic clozapine will undergo genotyping. These subjects will have an initial assessment at four weeks and regular follow-up assessments for a total period of 52 weeks. These subjects will be randomized to continued treatment with CLZ and augmentation with ATX or Placebo.

The purpose of the study is to assess the effectiveness and safety of long-acting injectable risperidone in the treatment of patients in the early stage of psychosis
NCT00290121
The purpose of this study is to understand, with the use of functional magnetic resonance imaging, the neural correlates involved in appetite control and the mechanism of weight gain in patients with schizophrenia treated with atypical antipsychotics. We hypothesize that a difference in cerebral activations between weight gaining and non-weight gaining patients will be detected after four months of treatment with olanzapine.
