Active clinical trials for "Bipolar Disorder"

The clinical use of clozapine has been an unequivocal advance in the treatment of schizophrenia, a chronic and severe mental illness. A wealth of clinical data demonstrates it offers enhanced efficacy on both positive and negative symptomatology, improving cognition, functioning and quality of life. It is also associated with improved compliance and a continued efficacy in long-term treatment that can be translated into a reduction of suicidality and all-cause mortality. Because of preclinical evidence that it modulates neuroplasticity and prefrontal cortex connectivity, clozapine may be an interesting strategy for further severe psychotic illnesses. Nevertheless, even considering the growing use of other atypical antipsychotics in the management of bipolar disorder, a role for clozapine has been poorly defined. The clinical evidence-base for its use in this condition is largely based on uncontrolled naturalistic trials and retrospective studies and chart reviews. Several of these have supported clozapine's efficacy in treatment-resistant bipolar disorder. Possibly because of clozapine's profile of adverse effects and lack of interest from pharmaceutical companies, only two randomized trials have examined its effectiveness. Both suggest clinically relevant antimanic and mood-stabilizing properties. Therefore, the primary objective of this trial is to determine the effectiveness of clozapine for treatment-resistant bipolar disorder. Secondary objectives include examining the effects of treatment with clozapine on cognition and functioning of patients with bipolar disorder. Tolerability and safety of long-term clozapine use will also be examined. To that end, the investigators will conduct a clinical trial with 54 patients with a history of treatment resistance. Patients will be randomized to either open-label treatment with clozapine, in combination with lithium or valproate, or open-label treatment with an atypical antipsychotic with consistent evidence of efficacy in the treatment of bipolar disorder (olanzapine, quetiapine or risperidone), also in combination with lithium or valproate. Patients will be followed for one-year and time to all-cause treatment failure will be the primary outcome measure. It is the belief of the investigators that this study will generate meaningful clinical data of tremendous importance to validate clozapine as a legitimate treatment option for treatment-resistant bipolar disorder.

The main goal of this study is evaluate the efficacy of memantine association on the treatment with a previous combination of two drugs, including quetiapine with lithium or quetiapine with aripiprazole in young patients with bipolar disorder type 1 non-responders or partial responders to that combination of drugs and evaluate the impact of this association at the cognitive functioning of the patients.

Effects of N-Acetyl-Cysteine in patients with bipolar depression (primary outcome is Hamilton Depression Rating Scale) with and without tobacco use disorder and on inflammatory and oxidative stress biomarkers

This study will investigate the effects of aerobic exercise on mental states, cognition, BDNF, and long-term outcomes in patients with bipolar disorder.

NMDA antagonist drugs have increasingly been demonstrated to reduce symptoms of depression and suicidal ideation. NeuroRx has developed a sequential therapy consisting of IV NRX-100 (ketamine HCL) for rapid stabilization of symptoms of depression and suicidal ideation followed by oral NRX-101 (fixed dose combination of D-cycloserine and lurasidone) for maintenance of stabilization from symptoms of depression and suicidal ideation. NRX-101 has been awarded Fast Track and Breakthrough Therapy Designation by the US Food and Drug Administration. The SevereBD study will test the hypothesis that NRX-101 is superior to lurasidone alone in maintaining remission from symptoms of depression (primary endpoint), clinical relapse (declared secondary endpoint), and suicidal ideation or behavior (declared secondary endpoint) over a six week period of twice-daily oral dosing.

Bipolar disorder (BD) is a severe brain disorder characterized by the recurrence of mood episodes. Depressive episodes in BD are frequently refractory and clinicians have few treatment options. Bright light therapy (BLT, also named phototherapy) is a promising emerging antidepressant strategy that is lacking evidence-based guidelines for its prescription in BD, including to avoid side effects such as manic switches. In this context, this study aimed to evaluate modalities of the BLT dosage (time of exposure) escalation depending on the tolerance (manic symptoms) in two groups exposed either during the morning or at mid-day.

This study aims to investigate the clinical efficacy of continuous theta burst stimulation (cTBS) on the right DLPFC as an add-on treatment in bipolar depression. The study consists of three phases. Phase 1: Bipolar depressed patients will be selected by a certified psychiatrist, who will administer (semi-)structured clinical interviews (M.I.N.I.-Plus 5.0.0, HRSD-17). The presence of exclusion criteria will be evaluated. Eligible patients will undergo MRI brain imaging for TMS neuronavigation Phase 2: Baseline clinical, cognitive and psychomotor assessments will take place. Patients will also undergo blood samples for laboratory and research assessments. TBS involves applying triple-pulse 50 Hz bursts given at a rate of 5 Hz uninterrupted trains (1). Patients will be treated with in total 20 continuous Theta Burst Stimulation (cTBS) session (900 pulses per session) over the right dorsolateral prefrontal cortex, which will be spread over 4 days. A stimulation intensity of 100% of the subject's resting motor threshold (rMT) of the right abductor pollicis brevis muscle will used. Patients will be randomized to receive either the real cTBS or sham treatment. Sham stimulation will be applied with a sham coil. The sham coil produces identical sounds but is not associated with a stimulus sensation compared to the coil delivering real stimulation cTBS. The investigators expect that real cTBS treatment and not sham will result in a significant and clinical meaningful response. Phase 3: Two post-treatment assessment moments will take place respectively 3 (max. 4) days and 10 (max. 11) days after the last treatment day. The assessments are the same clinical, cognitive and psychomotor assessments as in phase 2.

This is a parallel 3-group, multicenter, prospective, randomized, single-blind (evaluator) controlled pilot trial, with a 38- week follow-up. Patients diagnosed with bipolar disorder (BD) according to DSM -5 criteria for mild depression or subsyndromal depressive symptoms are assigned to one of the following 3 treatment groups: 1) psychopharmacological treatment plus Mindfulness Based Cognitive Therapy (MBCT); 2) psychopharmacological treatment plus structured group psychoeducation; 3) treatment as usual (TAU), including standard psychiatric care with standard pharmacologic treatment.

The purpose of this study is to evaluate whether repetitive transcranial magnetic stimulation (rTMS) treatment is an effective adjunct treatment to mood stabilizers and Bupropion.

The primary goals of this work are: a) to establish a unique collection of mood disorder patients across the life cycle, including children, adults and geriatric patients, with well-defined medical co-morbidities and medication treatment outcomes at the University Hospitals Case Medical Center Department of Psychiatry; b) to establish a collection of nuclear families, including both mothers and fathers, of children diagnosed with mood disorders; c) to perform a systematic genetic analysis of the proposed sample repository to identify genes and genetic variants contributing to inter-patient variability in clinical phenotypes and treatment responses. Our primary hypothesis is that genetic variations may underlie individual variability in disease susceptibility, clinical phenotypes and treatment safety, tolerability, and effectiveness.
