Active clinical trials for "Schizophrenia"

This study will evaluate the effects of sequential multiple dose regimens of cariprazine on cardiac repolarization in patients with schizophrenia.

This study described in the present protocol consists of two sections. Part A is the first administration into man to evaluate the safety, tolerability and pharmacokinetics of single ascending doses of GSK1144814. The study is a single-blind, randomised, placebo-controlled design in healthy male and female (of non-childbearing potential) subjects. Part B will be an open-label design in healthy male subjects to assess the GSK1144814 neurokinin-1 (NK1) receptor occupancy by positron emission tomography (PET) scanning with [11C]-GR205171

The purpose of this study is to determine how services should be provided to reduce symptoms and improve life functioning for adolescents and adults who have been recently diagnosed with schizophrenia.

This study is designed as a 3-part trial to evaluate the safety of a novel depot formulation of iloperidone, compare 2 depot dosage forms, and perform dose ranging of 1 chosen form in support of a monthly depot dosing regimen. In Phase A, the study is designed to evaluate the safety of a crystalline iloperidone depot formulation. In Phase B, the pharmacokinetic and safety profile of 2 depot clinical dosage forms will be compared, and 1 form will be selected for assessment in Phase C. Phase C of this study is designed to define the dose-exposure relationship of the selected form and to provide information that will permit a comparison of the risk-benefit ratio of several doses of the study drug to enable optimal dose selection for later studies.

This study will look at the impact of dosing as well as ongoing treatment with an investigation medication identified as PF-03654746, on cognitive and physiologic indicators of brain function. Data from this study will assist with the evaluation of the utility of functional magnetic resonance imaging, arterial spin labeling (ASL), and electrophysiologic measures in the detection of early signals of the effectiveness of medications developed to target cognitive impairment in schizophrenia. Safety and tolerability of PF-03654746 in this population will be also be evaluated.

The guiding questions for this study are: can a U.S. adaptation of a successful Scandinavian approach (TIPS) to early detection substantially reduce the duration of untreated psychosis (DUP) and improve outcomes beyond an established first-episode service (FES)? The primary aim of this study is: To determine whether an early detection intervention can reduce DUP in the US, as compared to usual detection. Early detection (ED) will be implemented in one US community (New Haven, CT), and usual detection efforts will continue in another (Boston, MA). DUP will be measured at admission to the corresponding first-episode services (STEP & PREP) in each community, over one year before and throughout ED implementation. The investigators hypothesize that DUP will be reduced significantly in the early detection site compared to the usual detection site; A secondary aim is to determine whether DUP reduction can augment the outcomes of established FES on outcomes in the U.S. The investigators will measure symptoms, functioning and engagement with treatment at entry and over 1 year at each site. The investigators hypothesize that shorter DUP at one FES (STEP) will predict reduced distress and illness severity at entry and better early outcomes at STEP compared to PREP.

The aim of the this study is to evaluate the effectiveness of methotrexate added to treatment as usual on positive and negative symptoms, cognitive and social functioning and quality of life of patients suffering from schizophrenia.

To characterize the pharmacokinetics (PK) of the injectable intramuscular (IM) long-acting formulation (in situ microparticle, ISM) of risperidone over four IM injections in the gluteal and deltoid muscle at 28-day intervals and at one dose strength (75 mg) in patients with schizophrenia.

This is a Phase 3, open label study administering RBP-7000 in the treatment of patients with schizophrenia. Study will assess the long-term safety and tolerability of RBP-7000 subcutaneous (SC) injections in subjects with schizophrenia and to continue collecting clinical outcome data with RBP-7000 SC injections in subjects with schizophrenia using the Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression-Severity Illness (CGI-S) scale.

The investigators will test the effects of 3 days of D-serine (DSR) on auditory plasticity in a sensory based remediation (SBR) paradigm
