Filter by:Lurasidone HCl is a compound that is a candidate for the treatment of major depressive with mixed features.This clinical study is designed to test how well Lurasidone works to treat major depressive disorder with mixed features.
This study is being done to look at how well people respond to two different drug treatments for depression. Clinically, people can respond differently to different treatments for reasons which are not always clear. Some research shows that people with a family history of bipolar disorder or completed suicide may react differently to standard medications used to treat depression than those without a family history. The investigators need to know if these drugs are effective to use in patients with depression who have a family history of bipolar disorder or completed suicide.
The purpose of this study is to evaluate the efficacy of scheduled maintenance Transcranial Magnetic Stimulation (TMS) treatment compared to on-demand TMS treatment for symptomatic worsening in patients who have shown a clinical response to acute TMS treatment.
This is a two part study. The objective of Part 1 is to evaluate the safety, tolerability, and pharmacokinetics of HT-2157 in healthy normal volunteers Part 2 is a randomized, double-blind, placebo-controlled, multiple (21-day) ascending-dose evaluation of the safety, tolerability, pharmacokinetics, and pharmacodynamics of HT-2157 in patients with major depressive disorder
Standard high frequency repetitive transcranial magnetic stimulation (HF-TMS) is a noninvasive method to activate or de-activate neurons in superficial regions of the brain through the induction of weak electric currents in the brain tissue produced by rapidly changing magnetic fields. Studies have generally shown standard HF-TMS to be effective in treating major depressive disorder (MDD), although treatment effects are often highly variable and there are several negative trials in the specialized literature. One reason for these discrepant results might be that standard HF-TMS only enables direct stimulation of superficial brain areas and, consequently, it is possible that the stimulation of deeper and more widespread brain regions could produce superior and more reliable results. Recently, a novel form of HF-rTMS (called deep transcranial magnetic stimulation or DTMS), that allows direct stimulation of much larger and deeper brain regions, has also been shown to be effective and safe in treating MDD. Neuroimaging studies have shown that standard HF-rTMS directly affects several superficial areas of the brain, but to date there is no data on the brain effects of DTMS. Thus, this study aims to explore, for the first time, the brain effects of DTMS in MDD. More specifically, we, the investigators, hope to identify possible neural predictors of clinical improvement after DTMS and also clarify the impact of DTMS in the brain activity over time. In this study, DTMS will be applied over the left side of the front of the head (a region known as the 'prefrontal cortex'), and will be compared with standard HF-TMS in terms of its effectiveness and brain effects. For this, subjects with at least moderate MDD will be randomized to receive daily DTMS or standard HF-rTMS treatment for 4 weeks, and will undergo functional magnetic resonance imaging (fMRI) before and after treatment. fMRI is a neuroimaging technique that allows us to measure which areas of the brain are more or less 'active' in response to specific stimuli at a particular time. During the fMRI sessions, we will use a validated cognitive task on working memory. Our results could eventually lead us, among other things, to identify which depressed patients would be best candidates for receiving either standard HF-rTMS or DTMS, and which areas of the brain should be targeted by these neuromodulation techniques.
We intend to investigate whether deep transcranial magnetic stimulation (DTMS), a novel brain stimulation technique, is effective for treating major depression. We hypothesize that 4 weeks of DTMS will be associated with significant improvements in depressive and anxious symptoms without significant side effects.
Primary purpose of this study is to determine if pregnenolone supplementation is associated with greater improvement in depressive symptoms of patients with bipolar disorder. Also the study will explore possibilities of improving anxiety and manic symptoms as well as the patient's cognition.
The purpose of this study is to compare the safety and efficacy of buprenorphine with placebo for adults with treatment resistant depression (TRD).
Major depression is characterized by vestibular anomalies. The investigators hypothesized that vestibular stimulation will improve depression symptoms in major depression patients.
The purpose is to assess the response of add-on therapy, based on CGI-I scale, at 4 weeks, in patients with MDD who had an inadequate disease control with antidepressant medication.
