NCT ID: NCT00805493 Terminated - Bipolar Disorder Clinical Trials

Double-Blind Placebo-Controlled Trial of Riluzole in Pediatric Bipolar Disorder

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

Pediatric Bipolar Disorder (BD) is uncommon in children. Its symptoms include periods of manic behavior (being overly happy or giddy, feeling grandiose, feeling a decreased need for sleep, having too much energy, moving more than usual, talking fast, having speeded-up thoughts and other symptoms). Sometimes there also is depression (extreme feelings of sadness or irritability, not taking pleasure in things, even ones that used to be enjoyable, feeling worthless or guilty, sleeping too much or having trouble getting to or staying asleep, feeling slowed down or restless, having wishes to be dead or suicidal ideas, and other symptoms). Pediatric BD is often difficult to treat; children may respond only partially to the medications now available or have too many side effects to tolerate them. Riluzole is a medication that is thought to work on a brain chemical called glutamate that may be involved in symptoms of depression and BD. Previous research studies have shown that riluzole may help adults with BD who have depression and adults who have depression, anxiety disorders, or obsessive-compulsive disorders. Riluzole may also be helpful for children with obsessive-compulsive disorder. However, it has never been given to children with BD. This study will evaluate the effectiveness of riluzole in 80 patients between 9 and 17 years of age who have BD and symptoms of anxiety. Participants must have tried at least two other medications that have not been effective. The study will consist of four phases carried out over 4 to 5 months. Most children will be inpatients at the Pediatric Behavioral Health Unit for at least part of the study. In Phase 1, each patient will undergo blood and urine tests, and will gradually taper off his or her medication. The duration of this phase depends on the medication that the patient was receiving before starting the study. In Phase 2, the patient will remain off all medication for 1 week. Throughout this time, patients will be monitored carefully and medication will be restarted if needed. In Phase 3, which lasts 8 weeks, patients will be assigned randomly to receive only riluzole or only a placebo. Those who receive riluzole will have the dose adjusted as needed. Patients and families will be informed of which drug they were on at the end of this phase. Patients who improved on riluzole may continue to receive it from NIH for 1 month and will then be prepared for discharge from the study. Patients who received placebo and improved, and those who received riluzole but did not improve, will be treated with standard medications as appropriate and prepared for discharge from the study. Phase 4 is for patients who received placebo and did not improve. They will be given the chance to try riluzole for 8 weeks and, if it is effective, continue it for an additional 4 weeks while they prepare to be discharged from the study. Patients will not be able to receive riluzole at the National Institutes of Health after the completion of the study. However, the child's doctor may be able to prescribe riluzole as an off-label use. Most patients will be admitted to the Pediatric Behavioral Health Unit at the National Institutes of Health Clinical Center during the medication withdrawal part of the study (Phases 1 and 2). From Phase 3 on, a patient may participate as an inpatient, outpatient, or in day treatment, depending on what is in his or her best interests. All participants in this study will be invited to also enroll in the National Institute of Mental Health protocol 00-M-0198, The Phenomenology and Neurophysiology of Affective Dysregulation In Children And Adolescents With Bipolar Disorder. Some research tests for that protocol will be done during the medication-free period of this protocol.

NCT ID: NCT00757497 Terminated - Schizophrenia Clinical Trials

Transcranial Direct Current Brain Stimulation to Treat Patients With Childhood-Onset Schizophrenia

Start date: September 17, 2008
Phase: Phase 1
Study type: Interventional

This study will test whether transcranial direct current stimulation (TDCS) can be used safely in children with schizophrenia and if it can improve memory and attention span or auditory hallucinations in these children, at least temporarily. TDCS has temporarily improved memory and attention span in healthy adults and a similar method called TMS has relieved auditory hallucinations in adults with schizophrenia. For the TDCS procedure, the child sits in a chair and two soft sponge electrodes are placed on the child s forehead and held in place with a soft wrapping. One sponge electrode is placed on an arm. The electrodes are attached to a stimulator with a wire. Children with schizophrenia who meet the following criteria may be eligible for this study: - Are 10 yrs or older age. - Are participating in NIH protocol 03-M-0035. - Are on a stable medication regimen for at least 6 months. - Have problems with memory and attention span or have auditory hallucinations. Participants are randomly assigned to receive either real or sham TDCS on an inpatient or outpatient basis in 20-minute sessions daily, except weekends, for 10 days. For real TDCS, patients receive stimulation to the front of the brain. For sham stimulation, the children have electrodes placed on the forehead, but no actual stimulation is delivered. In addition to TDCS, patients have the following procedures: - Checks of blood pressure, pulse and breathing rate before, during and right after each stimulation and again 8 hours later. - Electrocardiogram (EKG) and electroencephalogram (EEG) before starting stimulation and after completing the 10 days of TDCS. - Interviews and examinations to check for side effects of TDCS. - Pen-and-paper or computer tests of learning, attention and memory. - At the end of the 10 sessions, children who were in the sham TDCS group are offered the same number of sessions of active TDCS. - Follow-up telephone call 1 month after the end of stimulation to see how the child is doing. - 1- to 2-day outpatient visit 6 months after the stimulation. This visit includes interviews with the parent and the child, rating of the child s psychiatric symptoms, and pen-and-paper or computer tests of thinking, attention and memory.

NCT ID: NCT00750919 Terminated - Mental Disorders Clinical Trials

Twenty-six Week Extension Trial of Org 50081 (Esmirtazapine) in Outpatients With Chronic Primary Insomnia (176003/P05721/MK-8265-007)

Start date: October 7, 2008
Phase: Phase 3
Study type: Interventional

This trial is a 26-week, open label extension trial to investigate safety and explore efficacy of esmertazapine in participants with insomnia who completed protocol 21106/P05701/MK-8265-002 (NCT00631657).

NCT ID: NCT00746239 Terminated - Insomnia Clinical Trials

Ramelteon for Sleep Initiation Insomnia in Individuals With Panic Disorder Who Are Also on Escitalopram for Anxiety

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

Almost 80% of panic disorder patients report difficulty sleeping. Sleep disturbances in turn may exacerbate underlying anxiety/panic attacks. Moreover, individuals with insomnia (sleep disturbance) are at higher risk of developing a new anxiety disorder. Therefore it is expected that improving sleep quality with medications along with other medications to treat anxiety component of panic disorder might be helpful. However, there is lack of pharmacological studies examining the effects of improving sleep disturbances with medications in panic disorder patients, which is a critical problem for providing optimal care to these patients. The objective of this proposal is to determine the effects of ramelteon (FDA approved for insomnia) on sleep disturbances in Panic disorder patients who are on escitalopram for underlying anxiety.

Treatment of Schizoaffective Disorder Using Mifepristone

Start date: April 1998
Phase: Phase 2/Phase 3
Study type: Interventional

This study tests the hypothesis that mifepristone will diminish cognitive distortion and alleviate psychosis in patients with schizoaffective disorder.

NCT ID: NCT00715377 Terminated - Schizophrenia Clinical Trials

Anticholinergic Burden in Schizophrenia

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

Anticholinergic antiparkinsonian agents often cause side-effects including cognitive impairment, dry mouth, and constipation while they diminish antipsychotic-induced parkinsonian symptoms. The introduction of second generation antipsychotics (SGA) brought fewer neurological side effects. However, anticholinergic coprescription rates are still as high as 12-65% in patients on SGA that are much higher than the incidence of EPS reported in clinical trials (3-20%). This apparently discrepancy is likely explained, in part, by the established tradition of routine use of this medications. Older patients are particularly sensitive to anticholinergic side-effects due to age-related changes in pharmacokinetics and pharmacodynamics. In this study, we will examine the safety and benefits of reducing the dose of a frequently prescribed anticholinergics, benztropine, on cognitive function, extrapyramidal symptoms, and psychotic symptoms in older subjects with a primary psychotic disorder.
