NCT ID: NCT00461318 Completed - Psychosis Clinical Trials

The Effectiveness of Supported Employment for People With Severe Mental Illness: an RCT in Six European Countries

EQOLISE
Start date: April 2003
Phase: N/A
Study type: Interventional

The primary aim of the study was to determine the effectiveness of a form of supported employment, Individual Placement and Support (IPS) compared to existing good quality rehabilitation and vocational services for people with psychotic illnesses in terms of ‘open’ employment outcomes (in the competitive labour market), and to examine its relative effectiveness in the context of different European welfare systems and labour markets. The primary hypothesis was that IPS patients would be more likely to obtain open employment than control service patients. Secondary hypotheses were that they would be in open employment for longer than the control patients, and that they would not spend more time in hospital.

NCT ID: NCT00449397 Completed - Psychosis Clinical Trials

Dose Finding of Quetiapine Fumarate 200mg vs 400mg in First Episode Psychosis

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

The purpose of this study is determine the minimal effective dose and the impact on: 1. treatment outcomes at 4, 12 and/or 48 weeks the treatment has required to treat patients experiencing the first psychotic episode 2. the final maintenance doses 3. the use of other medications 4. the amount of changes to other antipsychotic medication 5. the number of hospitalization days

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: 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: NCT00281320 Completed - Psychosis Clinical Trials

Study of Asenapine in Elderly Subjects With Psychosis (A7501021)(P05717)

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

This study evaluates the safety and tolerability of Asenapine in elderly patients with psychosis.

NCT ID: NCT00272597 Completed - Schizophrenia Clinical Trials

Risperidone LA Heathcare Resource Study

Start date: September 2005
Phase: Phase 4
Study type: Interventional

The primary objective of this pilot study is to evaluate the impact of switching 30 subjects from an existing antipsychotic to risperidone long acting on healthcare resource utilization. The study will be a ten month open-label, 'mirror-image', pilot study. Healthcare resource utilization during the 10 months prior to starting risperidone long acting will be retrospectively collected for all subjects (period A) at the beginning of the study. The utilization of direct medical resources will also be collected for 10 months after initiation of risperidone long acting (period B). In this design the patients will serve as their own control.

NCT ID: NCT00237874 Completed - Schizophrenia Clinical Trials

Aripiprazole Treatment of Prodromal Patients

Start date: February 2004
Phase: Phase 2/Phase 3
Study type: Interventional

We hypothesize that symptoms will improve in patients who meet diagnostic criteria for the schizophrenia prodrome when they are prescribed aripiprazole.

NCT ID: NCT00175513 Completed - Psychosis Clinical Trials

V3: Vancouver-Victoria Valacyclovir Trial for Early Psychosis

Start date: September 2005
Phase: Phase 2
Study type: Interventional

This is an 18 week (2 weeks run-in, 16 weeks double blind) trial, to determine if an antiviral drug, valacyclovir (Valtrex) is helpful in treating the symptoms of psychosis, a form of a mental disorder.

NCT ID: NCT00009217 Completed - Alzheimer's Disease Clinical Trials

Treatment of Behavioral Symptoms in Alzheimer's Disease

Start date: January 1999
Phase: Phase 4
Study type: Interventional

The optimal strategy for the treatment of behavioral complications in patients with probable Alzheimer's disease (AD) remains unclear. The objective of this study is to evaluate the risk of relapse following discontinuation of haloperidol in patients with Alzheimer's disease (AD) with psychosis or agitation who respond to it. In Phase A of this study, AD outpatients with behavioral complications receive 20 weeks of open haloperidol treatment with an oral dose of 1-5 mg daily, titrated individually to achieve the optimal trade-off between efficacy and side effects. Responders to Phase A participate in Phase B, a 24-week continuation trial in which patients are randomized to continuation haloperidol or placebo. The primary outcome is the time to relapse of psychosis or behavioral disturbance.
