Filter by: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.
This study will assess efficacy, safety and tolerability of agomelatine (AGO178) 25 mg and 50 mg in patients with Major Depressive Disorder (MDD). This study includes an 8-week double-blind phase and a 52-week open-label phase.

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.
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.
A three-arm, randomized, double-blind, placebo-controlled, Phase 4, multicenter study to compare the efficacy and safety of atomoxetine versus placebo in children and adolescents aged 6 through 17 years with attention-deficit/hyperactivity disorder (ADHD) and comorbid oppositional defiant disorder (ODD) who are treated as outpatients in Germany. After an initial 3- to 28-day screening and washout phase, participants will be assigned to double-blind treatment with atomoxetine or placebo. A 2 week up-titration period will be succeeded by a 7 week treatment period at the target dose. The primary efficacy measure will be the Swanson, Nolan and Pelham Rating Scale Revised (SNAP-IV) ODD subscale score.
The purpose of this study is to determine whether individuals with obsessive compulsive disorder who will take a preparation of the amino acid glycine in addition to their current treatment, may experience improvement in their symptoms.
This study will examine the effectiveness of a multiple family group mental health service delivery strategy in improving mental health service use and outcome for urban, low income children of color, ages 7-11 years old with disruptive behaviors and their families.
This study will evaluate the effectiveness of a parent training program in improving parenting skills and reducing behavioral symptoms in young children who are at risk for developing childhood behavior disorders.
The purpose of this study is to determine the effects and cost-effectiveness of a Diagnostic Observation Center for PsychoGeriatric patients (DOC-PG). Our main hypothesis is that DOC-PG has added value compared with usual care regarding Health Related Quality of Life (HRQoL).
