Active clinical trials for "Schizophrenia"

This project will result in the development of a personalized intervention strategy to improve motivation for treatment engagement and functional outcomes in individuals with a recent onset of schizophrenia. Motivational impairment is arguably the single most important factor that determines a patient's ability to engage in and adhere to effective treatment. In our study, sixty participants will be enrolled in a randomized controlled trial comparing the feasibility and tolerability of two types of motivational interventions (Daily Goals or PRIME), and a neuroplasticity-based cognitive training program. Participants are randomized to either receive Daily Goals or PRIME for 8 weeks, after which, both conditions will also receive an 8-week course of cognitive training delivered via iPads. Participants will undergo pre/post-testing and a 6-month follow-up to determine feasibility and efficacy of the interventions. By enhancing motivation, schizophrenia patients would be able to engage more fully with treatment and develop full and productive lives. This study may also pave the way forward for other health conditions in which motivational impairments impede health outcomes. All assessments will be conducted at the University of California, San Francisco; however, we offer some assessments to be done remotely.

After successfully quitting smoking, smokers with schizophrenia are vulnerable to relapse shortly after discontinuation of treatment. The purpose of this study was to assess the feasibility and effectiveness of a 12-month relapse prevention intervention in recently abstinent smokers with schizophrenia. Subjects participated in a 12-week smoking cessation phase, where they received nicotine replacement therapy, bupropion SR 150mg bid, and cognitive behavioral therapy. If, at the end of the 12 weeks, they were able to demonstrate 1 week of abstinence, they continued in the relapse prevention phase of the study, where they continued to receive nicotine replacement therapy, bupropion SR 150mg bid, and cognitive behavioral therapy.

The purpose of this study is to evaluate the effect of AMG 747 on negative symptoms of schizophrenia in patients who are stable on current antipsychotic treatment. After a run-in period on their current antipsychotic treatment, patients will be randomized to one of the four treatment arms as add-on therapy for a treatment duration of up to 3 months.

Approximately one third of patients with schizophrenia show a poor response to standard treatment with antipsychotic medications. This treatment resistant group of patients represents a major challenge in everyday psychiatry, and consumes a disproportionate amount of time from the clinicians, resulting in considerable costs to the society and government. Anecdotal evidence suggests that the enzyme dipeptidyl peptidase IV (DPPIV) may be altered in patients with schizophrenia, with a higher level DPPIV enzyme activity being noted. We postulate that this may play a role in the neuropathology of schizophrenia patients and by inhibiting the DPPIV enzyme activity with a DPPIV inhibitor such as linagliptin, we will be able to improve and even ameliorate the symptoms of schizophrenic patients. However, until now there have yet any studies on the potential of these inhibitors in schizophrenia patients. A pilot study is thus proposed to evaluate the potential of the DPPIV inhibitor, linagliptin as an adjunct in schizophrenia patients who are non-responsive to treatment, which will establish the feasibility of a larger trial.

The purpose of the study is to determine whether two commonly-prescribed antipsychotic medications (aripiprazole and risperidone) have different effects on brain function and cognition in schizophrenia patients.

The purpose of this study is to compare the effect of oral paliperidone extended-release and oral risperidone immediate-release on cognitive function, especially the category fluency of Cognitive Abilities Screening Instrument, Chinese version (CASI C-2.0), in patients with an established diagnosis of schizophrenia.

This is a randomized, double-blind, active-controlled, 6 month study designed to evaluate the cognitive effects of treatment with CYP-1020 compared to risperidone. The primary efficacy endpoint will occur after 6 weeks of treatment; additional (secondary) efficacy endpoints will occur after 12 and 24 weeks of treatment. Up to 450 patients will be randomized to CYP-1020 or risperidone in a 1:1 ratio. The study will utilize a flexible dose escalation scheme designed to allow patients to titrate to their maximally tolerated dose; doses of CYP-1020 may range from a minimum of 15 mg to a maximum of 35 mg, whereas doses of risperidone will range from a minimum of 1 mg to 3 mg BID (2-6 mg daily). To ensure effective blinding across all treatment groups, all patients will be treated twice daily with study drug and/or placebo, as indicated (i.e., double-dummy design).

This is an open-label study consisting of a screening period, a conversion/titration phase (Phase 1), an open-label treatment phase (Phase 2), and a follow-up period. The study will enroll new subjects (hereafter referred as "de novo" subjects) with schizophrenia, or bipolar I disorder, manic or mixed episode with or without psychotic features, and rollover subjects with schizophrenia from 31-09-266 (hereafter referred to as "Study 266"). All de novo subjects must enter the screening period of the study. Subjects who are screened and are not required to go through Phase 1 will complete a Phase 2 baseline visit prior to their participation in Phase 2.

Schizophrenia patients treated with clozapine have a high prevalence of obesity-related metabolic syndrome. The condition is often poorly treated and may lead to the emergence of coronary heart disease and type 2 diabetes. The study will investigate whether structured treatment provided at the site of the outpatient psychiatric clinic of metabolic syndrome in this population will decrease the severity of metabolic syndrome as compared with usual care received by these patients in the community.

The primary purpose of the study is to evaluate the efficacy of bifeprunox in the maintenance phase of schizophrenia compared to placebo.
