Filter by:The purpose of this study is to evaluate minocycline as a potential treatment for bipolar depression when added to a mood-stabilizing medication. Minocycline is an antibiotic that is approved for the treatment of infections and acne. Participation in this research study is expected to last 8 weeks, and includes five outpatient visits.
This project will attempt to enhance and augment the antidepressant efficacy of a commonly used antidepressant in poorly responding bipolar depressed patients.
Long-term studies have emphasized that depressive symptoms and episodes account for majority of the illness burden experienced by individuals with bipolar disorder (BD). Previous studies have shown that blood levels of proteins called pro-inflammatory cytokines are abnormal in individuals with bipolar depression. The investigators hypothesize that preventing the production or release of pro-inflammatory cytokines will result in improvement of depressive symptoms in individuals with bipolar depression. Minocycline is a medication that inhibits the activation of immune cells (i.e. microglia) in the brain and reduces the production of pro-inflammatory cytokines. Treatment with minocycline has been shown to have antidepressant-like effects in animal studies and improve symptoms of individuals with schizophrenia. In this study, minocycline (100 mg twice a day) will be administered for 8 weeks to determine if it is an efficacious antidepressant for individuals with bipolar depression.
The investigators propose to study and compare measures of brain energy metabolism in geriatric bipolar individuals and healthy older adults. The investigators would also like to investigate changes in brain energy metabolites associated with CoQ10 administration in older bipolar individuals. Finally, resting state functional Magnetic Resonance Imaging (fMRI) will be conducted in order to explore frontal and limbic circuitry in geriatric bipolar disorder. - Primary Hypothesis: Baseline beta NTP and NAA will be lower, and PCr and lactate higher in Geri BPD compared with older healthy controls - Secondary Hypothesis: Changes in PCr and beta NTP will be demonstrated in Geri BD group challenged with CoQ 10.
Lurasidone HCI is a compound that is a candidate for the treatment of bipolar I depression. This clinical study is designed to test the hypothesis that Lurasidone in combination with either Lithium or Divalproex is effective among patients with bipolar I depression.
The primary objective of this study is to evaluate the superior efficacy of quetiapine extended release(XR) mono-therapy, administered once daily compared to placebo, in the treatment of depressive symptoms in patients with Bipolar I and Bipolar II Disorder
This study aims to study prospectively for 8 months a sample of bipolar patients with acute depressive episode in order to identify that factors associated with functional impairment, with especial attention to the presence of subsyndromal symptoms beyond the acute phase.
This study compared glutamate and other neurometabolites measured by proton magnetic resonance spectroscopy (1H-MRS) in bipolar I and II patients currently depressed with age-matched healthy controls. The study will also compare 1H-MRS of bipolar I and II patients before and after taking a 12-week course of lamotrigine. The goal of this study was to better understand the neurobiology of bipolar depression and how lamotrigine may therapeutically impact brain function and mood response. The hypothesis was that in comparison to non-remission participants, bipolar participants who achieve remission (defined as a Montgomery Asberg Depression Rating Scale (MADRS) score <12 at week 12) associated with lamotrigine monotherapy will exhibit a greater decrease in glutamate (Glu) and an increase in N-acetyl aspartate (NAA), reported as a cerebrospinal fluid (CSF)-corrected absolute concentration percent change from baseline to endpoint in anterior cingulate (AC) and dorsolateral prefrontal cortex (DLPFC).
This study will be a Proof of Mechanism (POM) study to establish evidence of central pharmacodynamic activity for PF 04455242, and will be a parallel group, randomized, double blind, sponsor open study conducted in healthy male subjects. Once subjects achieve steady state of PF 04455242, they will undergo PF 00345768 (spiradoline) challenge. Data will be analyzed to determine whether PF-04455242 blocks spiradoline induced prolactin release.
The purpose of this first in human (FIH) study is to investigate the safety, tolerability, pharmacokinetics ( how the body handles the drug) and pharmacodynamics (how the drug affects the body) of PF-04455242-01 in healthy adult volunteers.
