Active clinical trials for "Schizophrenia"

Schizophrenic individuals are typically nicotine dependent smokers who find it difficult to quit smoking. The purpose of this study is to determine the effectiveness of bupropion SR (commonly known as Zyban) in combination with a nicotine transdermal patch (NTP), in helping schizophrenic individuals quit smoking. In addition, this study will evaluate how the combination of bupropion SR and NTP affects psychiatric symptoms and medication side effects.

Controlled studies using the orthomolecular approach have been few (Deutsch, Ananth, & Ban, 1977). Those that were done were performed in chronic schizophrenia or in populations that included bipolar and schizoaffective patients. Both of these diagnostic groups are not today considered to benefit from the orthomolecular approach. Moreover, some negative studies of high-dose niacin were done in patients who were not otherwise given general counseling for good diet as described above. Therefore, this proposal is to study in a controlled manner carefully defined first onset schizophrenic patients using the protocol advocated by Osmond and Hoffer (1962). Patients can enter the study if they have been ill less than 1 year and are in their first hospitalization.

This study will examine the effects of ondansetron on auditory nerve activity in people with schizophrenia who are being treated with new antipsychotics.

Treatment with conventional antipsychotics such as haloperidol has little effect or may sometimes even worsen negative symptoms (such as blunted affect, emotional withdrawal, and poor rapport) of schizophrenia. The newer "atypical" antipsychotics agents, such as olanzapine, has shown improvement in the treatment of negative symptoms in acute trials. The purpose of this study is to compare an investigational compound (asenapine) with a marketed agent (olanzapine) in the treatment of stable subjects with persistent negative symptoms of schizophrenia for 6 months. Patients completing this study may be eligible to participate in an extension 6 months of treatment. Patients are required to have stable symptoms prior to entry into study.

The purpose of this study is to see if galantamine is an effective agent for the treatment of the cognitive abnormalities, negative symptoms, and /or behavioral impairments seen in schizophrenia.

To provide treatment to eligible subjects who have successfully completed one of the following phase III ziprasidone studies, A1281028, A1281044, A1281045 (NCT00136994) or A1281088 (NCT00143351).

A study to evaluate the efficacy and safety of two atypical antipsychotics vs. placebo in patients with an acute exacerbation of either schizophrenia or schizoaffective disorder

The purpose of this study is to determine the safety and efficacy of iloperidone compared to placebo and an active comparator in the treatment of patients with schizophrenia in acute exacerbation.

The purpose of the study is to compare the safety and tolerability of IR (Immediate-Release) quetiapine in a rapid escalation scheme with to the current approved label titration.

This study is being carried out to see if quetiapine (Seroquel) is effective in preventing patients from a schizophrenic relapse when studied for a long time (1 year) and if so, how it compares with non-active treatment.
