NCT01143077
Lurasidone (lurasidone HCl) is a novel psychotropic agent that is being developed as a potential new antipsychotic treatment for patients with schizophrenia. Switching between antipsychotic medications is common in the treatment of schizophrenia. The current study is designed to evaluate the effectiveness, safety, and tolerability of switching clinically stable, but symptomatic outpatients with schizophrenia or schizoaffective disorder from their preswitch antipsychotic medication to lurasidone, over a period of 6 weeks.
NCT01129674
The primary purpose of the study is to help answer the following research questions: How LY 2140023 can be tolerated by patients with Schizophrenia compared to standard of care treatment in 52 weeks time period. Whether LY 2140023 can help patients with Schizophrenia.
NCT00206128
The purpose of this study is to determine that the efficacy of the sustained release (SR) formulation of quetiapine (Seroquel) is not inferior to the immediate release (IR) formulation. PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation. The SR designation was changed to XR after consultation with FDA.
NCT01376076
This study will evaluate the effects of sequential multiple dose regimens of cariprazine on cardiac repolarization in patients with schizophrenia.
NCT00396214
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.
NCT00347425
The study will evaluate the safety and tolerability of switching subjects with schizophrenia or schizoaffective disorder from their existing antipsychotic medication to Bifeprunox.
NCT00051298
This study is to determine the efficacy (how well the drug works), safety, and any side effects of olanzapine compared to placebo in the treatment of schizophrenia in adolescents. Both the potential benefits and side effects of olanzapine will be evaluated throughout this trial.
NCT00034892
The purpose of this study is to compare the effectiveness, tolerability, and efficacy of the currently available atypical antipsychotic drugs olanzapine (2.5-20 mg/day), quetiapine (100-800 mg/day) and risperidone (0.5-4 mg/day) in patients with schizophrenia, schizophreniform disorder, or schizoaffective disorder who are experiencing their first psychotic episode.
NCT00090012
The purposes of this study are to determine: * The effectiveness of olanzapine as compared to quetiapine in treating and preventing the recurrence of a variety of symptoms of schizophrenia and schizoaffective disorder in patients who are obese or overweight. * The safety of olanzapine as compared to quetiapine.
NCT00366704
The purpose of this study is to determine the effect of bifeprunox or risperidone on the body weight of patients with schizophrenia.
NCT00946985
The study will assess the use of paliperidone palmitate compared with oral risperidone in delaying time to relapse in patients recently diagnosed with schizophrenia who are at high risk of relapse.
NCT00772005
The primary objective of the study is to evaluate whether armodafinil treatment is more effective than placebo as adjunctive therapy to antipsychotic medication in alleviating the negative symptoms of schizophrenia
NCT00337662
The current study has been designed to address the significance of early onset of response prospectively in patients treated with an atypical antipsychotic.
NCT00300963
The purpose of this study is to test the safety and effectiveness of talnetant vs. risperidone vs. placebo in reducing positive and negative symptoms in acutely psychotic schizophrenia patients.
NCT00361166
The primary purpose of this study is to determine whether a combination of ACP-103 (the study medication) with either haloperidol or risperidone will show antipsychotic efficacy and that it is safe and well tolerated. Further purposes of this study are to determine whether ACP-103, in combination with either haloperidol or risperidone, will enhance their antipsychotic effectiveness, demonstrate effectiveness against the negative symptoms, improve motoric tolerability, and is safe and well tolerated. This is a seven-week study (one week screening and six weeks of study medication) where a total of 400 patients who meet entrance criteria will randomly be assigned to receive one of five groups of study treatments of either low dose haloperidol plus ACP-103, low dose haloperidol plus placebo (a substance similar to a sugar pill), low dose risperidone plus ACP-103, low dose risperidone plus placebo, or high dose risperidone plus placebo. The study will begin with with a three to seven day drug-free period followed by six weeks of a stable daily dosage of study medication. Study subjects will be treated as hospital in-patients during screening and for the first 14 days of the study. Study subjects will be closely monitored throughout the study.
NCT00089869
Study of a medication for the treatment of Schizophrenia in patients who are already taking Abilify, Risperdal, Seroquel, Zyprexa
NCT00007774
Although currently marketed antipsychotic drugs are useful in the treatment of schizophrenia, efficacy and safety profiles need to be improved. Forty to eighty percent of patients either fail to respond or only partially respond to conventional antipsychotic agents. Secondary symptoms may be unimproved even in patients who respond to treatment. A variety of adverse events occur in patients receiving currently available agents. The severity of these events contributes to the poor compliance that is observed in this patient population. Olanzapine is a novel antipsychotic agent with a reduced incidence of extrapyramidal symptoms. Other side effects are minimal.
NCT01050582
The purpose of this study is to evaluate the effects of risperidone compared with other atypical antipsychotic drugs on the physical maturity, growth and development of children, and the risk of prolactin-related adverse events (side effects) associated to these drugs.
NCT00734435
The purpose of this study is to determine if zonisamide SR will prevent weight gain in schizophrenic subjects who take olanzapine (Zyprexa)
NCT00418171
The primary objective of the study is to estimate the relative incidence among users of ziprasidone and olanzapine of non-suicide mortality.
