NCT ID: NCT00337662 Completed - Schizophrenia Clinical Trials

Efficacy Study of Early Onset of Antipsychotic Drug Action in Schizophrenia

Start date: May 2006
Phase: Phase 4
Study type: Interventional

The current study has been designed to address the significance of early onset of response prospectively in patients treated with an atypical antipsychotic.

NCT ID: NCT00333658 Completed - Mental Disorders Clinical Trials

A Behavioral Intervention to Improve Work Outcomes

Start date: December 2003
Phase: N/A
Study type: Interventional

This research has been designed to learn whether getting regular and specific feedback about work performance with small rewards for meeting goals helps people to improve their job performance and leads to better work outcomes, improved mental functioning, and better quality of life

NCT ID: NCT00330863 Completed - Schizophrenia Clinical Trials

Preventing Relapse in Schizophrenia: Oral Antipsychotics Compared To Injectables: Evaluating Efficacy

PROACTIVE
Start date: May 2006
Phase: Phase 4
Study type: Interventional

This study is designed to find out whether taking antipsychotic medication once every two weeks by injection compared to taking daily oral medication will help people with schizophrenia maintain better control of their symptoms.

NCT ID: NCT00328978 Completed - Schizophrenia Clinical Trials

Seroquel STACK Study in Schizophrenic or Schizoaffective Subjects

Start date: October 2003
Phase: Phase 3
Study type: Interventional

The purpose of the study is to assess and compare the side effect profile, safety, tolerability and efficacy of schizophrenic or schizoaffective subjects non- or partially- responsive to 800 mg/day of quetiapine treated with either 800 mg/day or more than 800 mg/day of quetiapine during 8 weeks.

NCT ID: NCT00328276 Completed - Psychotic Disorders Clinical Trials

Sarcosine (N-Methylglycine) Monotherapy for Schizophrenia

Start date: December 2004
Phase: Phase 2
Study type: Interventional

The etiology of schizophrenia remains unclear. Schizophrenia patients reveal positive symptoms, negative symptoms, and cognitive impairments. In addition to dopamine system hyperactivity, hypofunction of N-methyl-D-aspartate (NMDA) receptor plays a role in the pathophysiology of schizophrenia. Consequently, enhancing NMDA receptor neurotransmission has been considered as a novel treatment approach. To date, there have been several trials on NMDA enhancers reported. For example, sarcosine (N-methylglycine, a glycine transporter I inhibitor) showed therapeutic effects not only in chronically stable patients but also in acutely exacerbated ones when added-on to antipsychotics. In addition, sarcosine yields excellent safety profiles, in comparison to current antipsychotics. It remains unclear whether NMDA enhancers, such as sarcosine, can serve as monotherapy for schizophrenia. The aims of this project are to examine the efficacy and safety of sarcosine monotherapy for acutely-ill schizophrenic patients, and to compare the effects of 2 grams/day, effective dose, with 1 gram/day, ineffective lower dose.

NCT ID: NCT00325689 Completed - Schizophrenia Clinical Trials

Aripiprazole Used as Dual Therapy in the Treatement of Patients With Chronic Stable Schizophrenia or Schizoaffective Disorder.

Start date: July 2006
Phase: Phase 4
Study type: Interventional

A Multicenter, Double-blind 16 Week Study on the augmentation of atypical antipsychotic with Aripiprazole in patients with Schizophrenia with inadequate response to antipsychotic treatment.

NCT ID: NCT00320736 Completed - Schizophrenia Clinical Trials

Galantamine for Cognition in People With Schizophrenia

Start date: January 2004
Phase: Phase 4
Study type: Interventional

This study is a double-blind, placebo-controlled trial of the nicotinic receptor agonist, galantamine, for the improvement of memory and attention in people with schizophrenia and schizoaffective disorder. Twenty subjects on a stable dose of antipsychotic medications receive galantamine or identical placebo tablets for 8 weeks. Adverse events are screened for every week. Tests of memory, attention, and reward responsivity are performed at baseline and afer 8 weeks on medication. Clinical scales rating psychiatric symptoms are performed at the beginning, middle, and end of the trial.

NCT ID: NCT00320723 Completed - Schizophrenia Clinical Trials

Nicotine Replacement Therapy for Smoking Cessation in Schizophrenia

Start date: July 2001
Phase: Phase 4
Study type: Interventional

This proposal seeks to evaluate a pilot smoking cessation treatment program that will combine nicotine replacement therapy with or without bupropion sustained-release (SR) with cognitive behavioral therapy for smoking cessation in patients with major mental illness.

NCT ID: NCT00320697 Completed - Schizophrenia Clinical Trials

Smoking Relapse Prevention in Schizophrenia

Start date: April 2006
Phase: Phase 4
Study type: Interventional

This study seeks to determine if continued treatment with bupropion and nicotine replacement therapy (NRT) can reduce the smoking relapse rate in patients with schizophrenia.

NCT ID: NCT00316303 Completed - Depression Clinical Trials

Effectiveness of the Screen, Test, Immunize, Reduce Risk, and Refer (STIRR) Intervention for People With Both a Mental and Substance Abuse Disorder

Start date: February 2006
Phase: Phase 2
Study type: Interventional

This study will determine the effectiveness of the STIRR (Screen, Test, Immunize, Reduce risk, and Refer) intervention in increasing rates of testing, immunization, referral, and treatment for blood-borne diseases, such as hepatitis and HIV, in people with both a mental disorder and a substance abuse disorder.
