NCT ID: NCT00421954 Completed - Bipolar Disorder Clinical Trials

Open-label Ziprasidone Study for Psychosis Treatment in Adolescents

Start date: May 2006
Phase: Phase 3
Study type: Interventional

This open-label study will assess the medication Geodon® (Ziprasidone) in pediatric patients, aged 13-17, diagnosed with psychotic disorder. Eligible adolescents will receive Geodon® for 7 weeks and stay at the NYSPI Children's Day Unit (CDU) during the day. If clinically appropriate, they may also stay at the New York State Psychiatric Institute (NYSPI) Schizophrenia Research Unit (SRU) inpatient facility.

NCT ID: NCT00420823 Completed - Psychotic Disorders Clinical Trials

A Study of Taurine in Patients With First-episode Psychosis Receiving Antipsychotic Treatment

Start date: January 2007
Phase: Phase 2/Phase 3
Study type: Interventional

The purpose of this study is to determine whether Taurine 4g is effective with antipsychotic medication in the treatment of First Episode Psychosis.Taurine may have an effect on cognition and symptoms. We are examining changes in symptoms and cognition over a 3 month period.

NCT ID: NCT00419146 Completed - Schizophrenia Clinical Trials

Treatment of Schizophrenia With an Omega-3 Fatty Acid (EPA) and Antioxidants

Start date: September 2001
Phase: Phase 2/Phase 3
Study type: Interventional

The purpose of this trial is to study the effect of adding the omega-3 fatty acid EPA and/or Vitamins E + C to antipsychotic drugs in younger patients with schizophrenia and related psychoses.

NCT ID: NCT00417482 Completed - Alzheimer Disease Clinical Trials

Antipsychotic Discontinuation in Alzheimer's Disease

ADAD
Start date: August 2004
Phase: Phase 4
Study type: Interventional

In patients with Alzheimer's disease (AD) who respond to antipsychotic treatment of psychosis and/or agitation/aggression, the relapse risk after discontinuation is not established. AD patients with psychosis and/or agitation/aggression receive 16 weeks of open risperidone treatment (Phase A). Responders are then randomized, double-blind, to one of three arms in Phase B: (1) continuation risperidone for 32 weeks, (2) risperidone for 16 weeks followed by placebo for 16 weeks, (3) placebo for 32 weeks. The primary outcome is time to relapse of psychosis/agitation.

NCT ID: NCT00412373 Completed - Clinical trials for Schizoaffective Disorder

Evaluation of Effectiveness and Safety of Flexible-dose Paliperidone Extended Release in Patients With Schizoaffective Disorder.

Start date: December 2006
Phase: Phase 3
Study type: Interventional

The purpose of this study is to measure the effectiveness and assess the safety of different dosages (from 3 mg/day to 12 mg/day) of the antipsychotic paliperidone extended-release (ER) in patients who are experiencing an acute episode of schizoaffective disorder.

NCT ID: NCT00410371 Completed - Mental Disorders Clinical Trials

Study to Compare Two Formulations of Lamotrigine in Healthy Subjects

Start date: December 28, 2006
Phase: Phase 1
Study type: Interventional

This study intends to compare the pharmacokinetic characteristics, safety and tolerability of two formulations of lamotrigine in healthy male and female volunteers

NCT ID: NCT00407732 Completed - Hepatitis C Clinical Trials

Overcoming Psychiatric Barriers to the Treatment of Hepatitis C

Start date: January 2007
Phase: N/A
Study type: Interventional

The purpose of this study is to develop and evaluate a 9-month psychosocial intervention that will assist patients with hepatitis C in overcoming barriers that prevent them from becoming appropriate candidates for interferon therapy.

NCT ID: NCT00407277 Completed - Schizophrenia Clinical Trials

Neural Inhibition as a Mechanism of Nicotine Dependence Among Persons With Schizophrenia

Start date: February 2007
Phase: N/A
Study type: Interventional

Cigarette smoking decreases life expectancy, causes devastating health complications, and costs society billions of dollars each year. These untoward consequences are especially pronounced among persons with schizophrenia (SCZ) because approximately 80% to 95% of this group smokes cigarettes. These high prevalence rates underscore the need for research investigating the determinants of smoking in patients with SCZ. Several researchers have observed that nicotine improves specific symptoms of SCZ including negative symptoms, negative affect, and cognitive deficits. This has led to the hypothesis that patients with SCZ smoke in an attempt to self-medicate. However, the mechanism(s) by which nicotine has its positive effect on symptoms remains unclear. The current proposal posits that neural inhibition (NI) is a physiological mechanism of this effect, while variation in the alpha-7-nicotinic receptor subunit gene (CHRNA7) represents the genetic underpinnings of these processes. The proposed study will assess NI and symptom improvement after acute administration of nicotine to both smokers and nonsmokers with SCZ. In addition, NI and CHRNA7 variation will be tested as predictors of patients' ability to reduce/quit smoking following smoking treatment. These data may lead to the development of new pharmacological strategies for treating the symptoms of SCZ and new methods for assisting these patients to quit smoking.

NCT ID: NCT00406718 Completed - Schizophrenia Clinical Trials

Improving Adherence to Oral Antipsychotic Medications in People With Schizophrenia

Start date: November 2006
Phase: N/A
Study type: Interventional

This study will determine the comparative effectiveness of two systems designed to improve medication adherence in people with schizophrenia.

NCT ID: NCT00406315 Completed - Schizophrenia Clinical Trials

Study Evaluating The Safety, Tolerability, And Efficacy Of Switching From Quetiapine To Ziprasidone

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

The primary objective of this study is to evaluate change in weight as a result of switching from quetiapine to ziprasidone, in subjects with schizophrenia or schizoaffective disorder who have failed to achieve a satisfactory clinical response to quetiapine due to lack of efficacy or poor tolerability.
