Active clinical trials for "Bipolar Disorder"

This study is designed to evaluate the safety and effectiveness of an investigational procedure for treating people with treatment resistant bipolar depression (TRD). Precise dose delivery of radiation to the predetermined targets in the brain will be accomplished with known Cyberknife stereotactic radiosurgery methods. This technology is considered to be noninvasive (does not physically invade your body). We will be studying if the Cyberknife influences the sensitivity of certain nerves of your brain. Although many clinical treatments for psychiatric conditions have been done using stereotactic radiosurgery, the present study is experimental, because we are seeking to use more moderate doses of radiation that are intended not to destroy any brain cells, but to normalize or modulate their function.

This is an open-label study consisting of a screening period, a conversion/titration phase (Phase 1), an open-label treatment phase (Phase 2), and a follow-up period. The study will enroll new subjects (hereafter referred as "de novo" subjects) with schizophrenia, or bipolar I disorder, manic or mixed episode with or without psychotic features, and rollover subjects with schizophrenia from 31-09-266 (hereafter referred to as "Study 266"). All de novo subjects must enter the screening period of the study. Subjects who are screened and are not required to go through Phase 1 will complete a Phase 2 baseline visit prior to their participation in Phase 2. Study Design: Treatment, Single Group Assignment, Open Label, Active Control, Safety/Efficacy Study

The purpose of this study is to determine whether a single intravenous administration of an N-methyl-D-aspartate antagonist is safe and effective for the acute treatment of bipolar depression.

This pilot study will evaluate the efficacy of the monoamine oxidase inhibitor (MAOI)EmSam, a selegiline transdermal system (STS), in bipolar depression.

The purpose of this research study is to find out whether Maca Root is effective for treating sexual dysfunction in females that is caused by the treatment for bipolar disorder. An additional aim of the study is to document the safety and tolerability of maca root, as well as any potential side effects that it causes. We suspect that Maca Root will result in a significant reduction in sexual dysfunction when compared to a placebo group.

This study is being done to look at how well people respond to two very different drug treatments for depression. Clinically, people with depression can respond differently to drug treatments for reasons which are not always clear. Some of our own recent research suggests that people with depression who have a family history of bipolar disorder or completed suicide, may react differently to standard antidepressant medications than those without such a family history. Our data shows that family history of completed suicide, as well as the known predictor of family history of bipolar disorder, may help identify a pre-bipolar high risk group i.e. they currently have depression but at some future date will declare a bipolar illness (manic-depression) by virtue of development of a manic episode also. Our research suggests that treatment- emergent symptoms in response to a trial of antidepressant, such as agitation may be strong predictors of future bipolarity and inherently dangerous particularly as they are not ascribed to the antidepressant treatment. Finally, it is possible that this subgroup of those with depressive illness may respond better and more safely to lithium, a mood stabiliser used in known bipolar depression. The objective of this proposal is to investigate response to acute lithium treatment in subjects who meet the diagnostic criteria for major depression, but who are potentially at risk for bipolar disorder, by virtue of family history of bipolarity or completed suicide.

GW273225 is in development for epilepsy and bipolar disorder and can affect women of child bearing potential. A clear understanding of the potential interaction between oral contraceptives and GW273225 is therefore important for clinical investigation of GW273225 in a large number of patients. This study will investigate whether there is any effect of GW273225 upon the components of combined oral contraceptive, and also whether taking oral contraceptives affects the pharmacokinetics (PK) of GW273225. 26 healthy female subjects, aged 18-45 years will take an oral contraceptive (150ug levonorgestrel and 30ug ethinylestrdiol; The study will include a screening period, two cycles on oral contraceptive with GW273225 at 25 mg once per day administered from the start of the second COC cycle for 47 days. There will be a follow-up visit 14-21 days later.

The purpose of this study is to compare the efficacy and tolerability of ziprasidone versus olanzapine in the treatment of acute mania. An open label extension will further evaluate the efficacy, safety, and tolerability of ziprasidone compared with olanzapine. Study recruitment was stopped due to difficulty in enrolling the targeted number of patients on July 30, 2007. Subjects that were enrolled at the time completed the study as per protocol. There were no safety concerns involved in the decision to stop enrollment. The Last Subject Last Visit was January 10, 2008.

A previous study showed that the intravenous administration of scopolamine produces antidepressant effects. This study is designed to determine if other routes of administration of scopolamine produce antidepressant effects.

To determine if adding Escitalopram to current mood stabilizer (MS) or atypical antipsychotic (AA) will improve in rates similar to or better than adding a placebo (inactive pill)in resistant bipolar patients.
