Active clinical trials for "Schizophrenia"

The primary objective of this study is to determine if NAC, added to existing antipsychotic treatment, is superior to placebo for cortical erosion in patients with early stage psychosis. The primary hypothesis is that there will be significantly less cortical erosion as measured by cortical thickness, cortical volume and cortical white matter density (assessed by DTI) in patients treated for 12 months with NAC as compared to those treated with placebo. The secondary objectives of this study are to determine if 12 months of NAC add-on treatment is superior to placebo for fMRI determined working memory and semantic memory tasks, cortical MR spectroscopy measures (glutathione, N-acetylaspartate, and glutamine/glutamate levels), electrophysiologically determined attention measures (e.g., mismatch negativity, P300), symptoms, functional measures and cognitive functioning.

This stage 1 clinical trial will determine pilot efficacy, develop a therapy manual, and collect qualitative data concerning a brief money management intervention for people disabled by psychiatric illnesses.

The purpose of the present study is to examine whether cognitive behavior therapy will reduce depressive symptoms and increase self-esteem for patients with a first episode psychosis.

A Randomized, Double-blinded, Double-dummy, Parallel-controlled and Multicenter Clinical trial to Investigate Blonanserin in Treatment of Schizophrenia when compared with Risperidone

Auditory verbal hallucinations (AVH) are a characterising symptom of schizophrenia. In the majority of patients, these AVH respond well to antipsychotic medication. Yet, a significant minority continues to experience frequent AVH despite optimal pharmacotherapy. The number of alternative treatment options for this medication resistant group is currently low and most of them focus on coping with the hallucinations. Transcranial magnetic stimulation (TMS), in contrast, is a non-invasive technique of influencing cortical excitability. This technique has the potential to actually decrease the frequency and severity of medication resistant hallucinations. Several previous studies have assessed efficacy of low frequency rTMS, with contradicting results. A previous large study by the investigators group could not demonstrate efficacy of low frequency rTMS. A new stimulation protocol using theta burst rTMS (TBS) could provide a more effective therapeutic option. Objective: The present study aims to examine the efficacy of TBS on the severity of AVH. Study design: The objectives are tested in a randomized double blind placebo-controlled trail. Study population: 60 patients with the diagnosis of schizophrenia, schizoaffective disorder, schizophreniform disorder or psychosis not otherwise specified with frequent auditory verbal hallucinations will be included. Intervention: The participant will receive either 10 TBS treatments or 10 placebo treatments consisting of 900 pulses each with a 30 minute interval on the left temporoparietal area, distributed over 5 treatment days. Stimulation will be at 80% of the motor threshold. Main study parameters/endpoints: the main study parameter is the change in the severity of the AVH. The secondary study parameter is the number and severity of adverse events.

This study explores the tolerability, safety and efficacy (i.e. how well the drug works) of flexibly dosed paliperidone palmitate in the treatment of schizophrenia in patients previously unsuccessfully treated with other oral or long-acting injectable (LAI) (i.e. with a long duration of action) antipsychotics.

This is a one-week, randomized, double blind add-on study of valaciclovir versus placebo in 24 clinical patients with Schizophrenia according to DSM IV, currently experiencing psychosis as is defined by the positive items of the Positive and Negative Syndrome Scale (PANNS) score, being five or higher on one item or four on two items of this scale. Each patient will be randomized to double blind treatment with either valaciclovir or placebo for one week. The main objective is to find a pre- and post-valaciclovir treatment difference in hippocampal inflammation, as measured with positron emission tomography. The secondary objective is to improve cognition by the supposed anti-inflammatory effect on the hippocampus of valaciclovir. This is measured by pre- and post-treatment performance on the PANSS, the attention and memory test. Both the treatment team and the patient will remain blinded during the course of the study. Following the active treatment phase, patients will receive treatment as clinically indicated.

This is a phase 1, randomized (a process that is used to decide whether you will take study drug or a placebo during the study), inpatient study which will assess the safety and tolerability of HTC-867 in healthy male Japanese subjects.

Accumulating evidence suggests a role of oxidative stress in the pathophysiology of schizophrenia. The potent antioxidant sulforaphane (SFN) is an organosulfur compound derived from a glucosinolate precursor found in cruciferous vegetables such as broccoli, Brussels sprouts and cabbage. The protection afforded by SFN is thought to be mediated via activation of the NF-E2-related factor-2 (Nrf2) pathway and subsequent up-regulation of phase II detoxification enzymes and antioxidant proteins, through an enhancer sequence referred to as the electrophilic responsive element or antioxidant responsive element. Recently, we reported that SFN could attenuate behavioral abnormalities in mice after the NMDA receptor antagonist phencyclidine. Considering the potent antioxidant effects of SFN, we have a hypothesis that SFN would be a potential therapeutic drug for schizophrenia. The purpose of this study is to determine whether SFN-rich broccoli sprout extract have beneficial effects in patients with schizophrenia.

The purpose of this study is to assess the pharmacokinetics (the study of the way a drug enters and leaves the blood and tissues over time) and safety of paliperidone palmitate in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self).
