Active clinical trials for "Schizophrenia"

This study includes two main components: the first screening phase and the second clinical intervention phase. During the screening phase, subjects with poor response to clozapine are carefully evaluated by chart-review and clinical assessment. Via chart-review, clinical data of diagnosis, disease course and previous treatment outcome, and concomitant psychotropic agents are obtained. Clinical phenomenology, including psychopathology, psychotic and mood symptoms severity and side effect of psychotropic medication are assessed by clinical interview and observation, which are conducted by experienced clinicians. Blood sample will be also obtained from the subjects for measuring the baseline clozapine drug level and extracting DNA for further analysis. Subjects fulfilling the criteria of treatment-resistant schizophrenia with poor response to adequate dose and duration of clozapine treatment are eligible for the clinical trial phase of 14-week randomized, placebo-controlled amisulpride add-on study. In this phase, subjects are randomly allocated to amisulpride augmentation treatment group and placebo treatment group. Subjects in the former group will receive clozapine and amisulpride combination treatment, while in the latter group will receive clozapine and placebo. Outcomes of clinical efficacy and safety are carefully evaluated by experienced and well-trained research stuffs in the 14 weeks of clinical study period. All of the above studies will be conducted in four hospitals, including DOH Bali Psychiatric Hospital, DOH Tao-yan Psychiatric hospital, and the Ju-Shang Psychiatric Hospital. Subjects will be recruited from the chronic in-patient settings from these three hospitals.

This randomized trial is examining whether a treatment called cognitive remediation is more effective when it is paired with a social and functional skills training component.

GSK1144814 is a potent, insurmountable antagonist at human neurokinin-1 (NK1) and neurokinin-3 (NK3) receptors with the potential to treat multiple symptom domains of schizophrenia and be an efficacious antidepressant. This study will be an open label, randomised, three-way cross-over study to evaluate the safety, tolerability and pharmacokinetics of a new tablet formulation of GSK1144814 and to evaluate the effect of food on single oral doses of GSK1144814 in healthy male and female subjects.

This was a double-blind randomized study with three treatment arms: clozapine, olanzapine and haloperidol. We compared these three medications in the treatment of aggressive behavior over a 12 week period.

The aim of this study is to evaluate the overall effectiveness of Ondansetron as an adjunctive or "add-on" medication in the treatment of Schizophrenia. This study is a double blind, placebo-controlled, randomised, 12 week trial.

This randomized, double-blind, placebo-controlled parallel group study will assess the effect on biomarkers measures of cognitive dysfunction, the clinical efficacy and safety of RO4917838 in participants with schizophrenia and schizoaffective disorder. Participants will be randomized to receive either RO4917838 (10 milligrams [mg] daily orally) or placebo for 6 weeks, in addition to their stable antipsychotic medication. Anticipated time on study treatment is 6 weeks.

The primary objective of this study was to continue to provide aripiprazole intramuscular (IM) depot treatment (400 milligrams [mg] or 300 mg) to participants with schizophrenia completing the 52-week, open-label safety and tolerability Study 31-08-248. In addition, the secondary objective was to collect additional long-term safety data on aripiprazole IM depot treatment.

Open-label safety study of oral olanzapine treatment in adolescents, aged 13 to 17 years, with bipolar I disorder (manic or mixed episodes) or schizophrenia.

The purpose of this study is to evaluate the effects of a CYP2D6 inhibitor, paroxetine, on the pharmacokinetics of a single dose of orally administered paliperidone ER and to evaluate the safety and tolerability of both treatments in healthy men

The primary purpose of this study is to evaluate the pharmacokinetics and relative bioavailability of paliperidone ER formulations with slow, target, and fast in vitro release rates after administration of a single 12 mg dose. The slow and fast releasing ER tablets have in vitro release rates outside the current commercial specifications. Therefore, in order to support widening of the specification limits, this study will be performed. The target formulation to be used is representative of the commercial formulation. Other objectives of this study are 1) to compare the relative bioavailability of paliperidone ER formulations with slow, target, and fast in vitro release rates to the paliperidone IR formulation; 2) to explore the in vitro in vivo correlation (IVIVC) for the paliperidone ER formulation; and 3) to evaluate the safety and tolerability of the different paliperidone ER formulations.
