NCT ID: NCT00728923 Completed - Clinical trials for Obsessive Compulsive Disorder

Pilot Study of Minocycline (NPL-2003) in Adults With Obsessive-Compulsive Disorder (OCD)

Start date: August 2008
Phase: Phase 2
Study type: Interventional

Obsessive-compulsive disorder (OCD) is a common psychiatric illness that affects up to 2-3% of the population. People with OCD experience anxiety-provoking, intrusive thoughts, known as obsessions, and feel compelled to perform repetitive behaviors, or compulsions. The only medications proven effective for OCD are serotonin reuptake inhibitors (SRIs), but even with SRI treatment, most patients continue to experience significant OCD symptoms, impaired functioning, and diminished quality of life. Recent evidence suggest that a different neurotransmitter, glutamate, may contribute to the symptoms in OCD. Medications that target glutamate hold promise for ameliorating symptoms for those patients continuing to suffer from OCD. In this study we are recruiting patients to receive the drug NPL-2003, which is thought to modulate the neurotransmitter glutamate, added to whatever other OCD medications they are taking in a 12-week open label study.

NCT ID: NCT00724490 Completed - Clinical trials for Obsessive Compulsive Disorder

Unilateral Deep Brain Stimulation (DBS) of the Nucleus (Nucl.) Accumbens (Acc.) in Patients With Treatment Resistant Obsessive Compulsive Disorder (OCD)

Start date: February 2004
Phase: N/A
Study type: Interventional

The purpose of the study was to evaluate whether a unilateral Deep Brain Stimulation of the right Nucleus Accumbens could lead to a more than 35% reduction of symptoms in patients with a treatment resistant Obsessive Compulsive Disorder within two years.

NCT ID: NCT00723060 Completed - Clinical trials for Obsessive Compulsive Disorder

Comparison of Effects Between Conventional Dose and High Dose Escitalopram on Clinical Improvement in Patients With Obsessive-compulsive Disorder

Start date: September 2008
Phase: Phase 4
Study type: Interventional

OBJECTIVE: The objective of this study is to compare the effect and safety of conventional dose (20mg) and high dose (40mg) of escitalopram in patients with obsessive-compulsive disorder (OCD). OVERVIEW OF STUDY DESIGN: Prospective, Randomized, Active-controlled, Double-blind, Multi-center, Clinical Trials STUDY POPULATION: Patients with OCD EFFICACY EVALUATIONS: Y-BOCS (D-YBOCS), HAM-D, HAM-A, CGI-S & -I, GAF, OCI-R SAFETY EVALUATION: Adverse Events / Serious Adverse Events, UKU

NCT ID: NCT00690729 Completed - Clinical trials for Obsessive-Compulsive Disorder

Cognitive-Behavioral Bibliotherapy for the Treatment of Obsessive Compulsive Disorder in Children and Adolescents

Start date: July 2005
Phase: N/A
Study type: Interventional

This 16-week program examines cognitive behavioral bibliotherapy to typical therapist-directed cognitive behavior therapy for children and adolescents with Obsessive Compulsive Disorder.

NCT ID: NCT00680602 Completed - Clinical trials for Obsessive Compulsive Disorder

Group Cognitive Behavioral Therapy Versus Fluoxetine for Obsessive-Compulsive Disorder: a Practical Trial

GCBTVF
Start date: January 2006
Phase: Phase 4
Study type: Interventional

First line treatments fo Obsessive Compulsive Disorder (OCD) are Selective Serotonin Recapture Inhibitors (SSRIs) and Cognitive Behaviour Therapy (CBT) including exposure with response prevention. The aim of the present study is to evaluate the clinical efficacy of GCBT and SSRIs for OCD patients. Other clinical trials have compared these treatments, but with OCD patients without any other psychiatric disorder. In this study patients with current age between 18 and 65 years, with YBOCS score of at least 16 and psychiatric comorbidities will be not excluded. Exclusion criteria will be: OCD secondary to brain trauma, stroke or malformation; current abuse of alcohol or other psychoactive substance, current presence of psychotic symptoms, suicidal risk, psychiatric or clinical comorbidity that might get worse with the medications used in the trial. So, the present study investigates the efficacy of these treatments for a heterogeneous OCD population, trying to identify if the usual treatments are efficient when applied in the public health system that treat not just patients with only OCD diagnosis. Patients will be randomized for GCBT and SSRI, and after treatment will be evaluated by researchers blind to the treatment received.

NCT ID: NCT00674219 Completed - Clinical trials for Obsessive-Compulsive Disorder

Memantine Treatment for Obsessive-compulsive Disorder and Generalized Anxiety Disorder

Start date: May 2005
Phase: Phase 3
Study type: Interventional

The objective of this study was to obtain preliminary open-label data on the efficacy and tolerability of memantine, an anti-glutamatergic medication with a unique pharmacodynamic profile, in individuals with OCD and individuals with GAD. Because glutamatergic hyperactivity in frontal and frontal-subcortical circuits may play a role in the symptomatic expression of OCD, and possibly GAD, agents that reduce glutamatergic neurotransmission should provide unique anti-stress and anti-obsessional benefits. Memantine is a specific, uncompetitive antagonist at the NMDA receptor that blocks sustained activation of the NMDA receptor by high concentrations of glutamate under pathological conditions but rapidly leaves the NMDA channel upon transient physiological activation by low concentrations of glutamate.

NCT ID: NCT00632229 Completed - Clinical trials for Obsessive-Compulsive Disorder

Double Blinded, Placebo-Controlled Trial of Paliperidone Addition in SRI-Resistant Obsessive-Compulsive Disorder

Start date: October 2007
Phase: Phase 2
Study type: Interventional

Obsessive-compulsive disorder (OCD) is a common, chronic, and oftentimes disabling disorder. The only established treatments for OCD are a specific form of Cognitive Behavioral Therapy (CBT) and the Serotonin Reuptake Inhibitor medications (SRIs). Few patients with OCD experience complete symptom resolution with either modality and even after two consecutive SRI trials, as many as 30%-40% of patients fail to derive a satisfactory response. Pharmacological options for these SRI-resistant cases include switching to a different antidepressant, increasing the dose of SRI, or augmentation with another agent. Previous studies showed that approximately 33-50% of OCD patients who have not had an adequate response to SRI medication had a positive response when an atypical antipsychotic medication was added. However, the problematic acute and long-term side effects of these medications are of concern and, at times, limit their use. Paliperidone has a number of advantages over these medications including fewer drug interactions and better tolerability. Thus, this study is designed to determine whether paliperidone augmentation of an existing medication is effective relative to taking a placebo and your existing medication.

NCT ID: NCT00616486 Completed - Clinical trials for Obsessive Compulsive Disorder

rTMS in Treatment of Obsessive Compulsive Disorder (OCD)

Start date: January 2008
Phase: N/A
Study type: Interventional

Low frequency (1Hz) rTMS applied bilaterally and simultaneously over SMA for 6 weeks in addition to the standard treatment regimen for OCD, will lead to significant improvement in patients' symptoms. The clinical improvement detected by YBOCS, CGI and SF-36 QOLS scores will be statistically significant in active treatment group compared to sham (placebo) treatment group.

NCT ID: NCT00590642 Completed - Clinical trials for Obsessive Compulsive Disorder

Augmentation in Tx-resistant OCD: an Open Label Trial

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

This study examines the use of Acamprosate (Campral(R)) in the treatment of Obsessive Compulsive Disorder (OCD). The treatment of this condition is difficulty and a large percentage of patients fail to respond to medications and have residual symptoms. Such patients are referred to as having treatment resistant OCD.

NCT ID: NCT00564564 Completed - Clinical trials for Obsessive Compulsive Disorder

Quetiapine Augmentation Versus Clomipramine Augmentation of SSRI for Obsessive-compulsive Disorder Patients

QCAT
Start date: January 2006
Phase: Phase 4
Study type: Interventional

The objective of this trial is to compare in an open trial format the efficacy of association of clomipramine and quetiapine with SSRI after SSRI treatment failed to produce complete remission of obsessive compulsive disorder symptoms.
