Filter by:Existing treatments for major depressive disorder (MDD) generally take weeks to months to exert their maximal benefit. There is an urgent need to develop rapid-acting treatments for MDD. Ketamine, a high-affinity N-methyl-D-aspartate (NMDA) glutamate receptor antagonist, has been used as a standard intravenous (IV) anesthetic agent for many years in both pediatric and adult patients. Beyond its well-established role in anesthesia and pain management, there is emerging evidence that ketamine may have rapid antidepressant properties for patients with severe mood disorders. In this study we are investigating whether ketamine can have an antidepressant effect compared to midazolam. Midazolam has similar anesthetic effects compared to ketamine but has not been shown to be an antidepressant, and is therefore acting as an active control in this study. The study period can last up to 8 weeks, depending on your response to the study medication. There are two required overnight stays in our Research Commons as part of this study.
This study will investigate the additional benefits of telephone-based cognitive behavioral therapy (Tel-CBT) as added treatment to an antidepressant (escitalopram) in working people with major depressive disorder (MDD) versus treatment with escitalopram alone. Outcomes will include depression symptom rating scales and measures of work absence and productivity. The hypothesis is that Tel-CBT and escitalopram will result in better outcomes than escitalopram alone in working patients with MDD.
The purpose of this study is to determine the safety and tolerability of a new drug, GSK163090, which is being developed for the treatment of depression and anxiety disorders.
The purpose of this randomized, double-blind, placebo-controlled study is to assess the safety and efficacy of PRX-00023 in patients with major depressive disorder.
This study will assess efficacy, safety and tolerability of agomelatine (AGO178) 25 mg and 50 mg in patients with Major Depressive Disorder (MDD). This study includes an 8-week double-blind phase and a 52-week open-label phase.
The study is to investigate the non-inferior efficacy of Paroxetine Controlled Release to Paroxetine Immediate Release, as well as the drug tolerability profile when treated on patients with Major Depression.
This is a study to obtain clinical experience of 323U66 SR for elderly patients with depression in repeat-dose of 323U66 SR up to 300mg/day, and to conduct exploratory investigation on safety, efficacy and pharmacokinetics profile in elderly patients with depression.
