Active clinical trials for "Depressive Disorder, Major"

To examine the efficacy of Almond Therapy compared to Treatment as Usual when used in addition to an approved version of intranasal esketamine.

The purpose of the study is to examine whether an investigational medication called ketamine along with psychotherapy is an effective treatment for depression in participants with a history of opioid addiction who have not abused opioids in at least 3 months. Participants will receive ketamine through intramuscular injection along with psychotherapy weekly for 8 weeks. Participation for eligible subjects who decide to enroll (including post-medication follow-up visits) will last about 16 weeks or 4 months.

Ketamine has been shown to have an antidepressant effect when given intravenously in doses of 2mg/kg. Ketamine is used as a standard induction drug during general anesthesia. It is known in this instance to decrease postoperative pain. No one has studied whether or not ketamine when given in doses used during general anesthesia (0.5mg/kg intravenous) has an antidepressant effect on surgical patients who suffer from depression. The study is designed to determine whether or not a small dose of ketamine when given at the induction of anesthesia could have an antidepressant effect on surgical patients with depression.

The purpose is to study the efficacy and safety of ABT-436 in Major Depressive Disorder.

Double-blind, placebo-controlled, multiple ascending oral dose evaluation of the safety, tolerability, and pharmacokinetics of DSP 1053 and its metabolites in healthy subjects and in subjects with major depressive disorder

To evaluate if somatosensory evoked potentials (SEPs) and motor evoked potentials (MEPs) obtained with electroencephalography (EEG) and electromyography (EMG) can be used to detect changes in cortical plasticity in responders to a single IV infusion of ketamine as compared to non-responders.

This proposed study sets out to examine the antidepressant effects of tocilizumab among patients with treatment-refractory major depression.

The purpose of this study is to evaluate the safety and efficacy of filorexant (MK-6096) versus placebo as adjunctive treatment for major depressive disorder (MDD), in participants who are partial responders to antidepressant monotherapy with one of identified selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs), or bupropion. The primary hypothesis of the study is that filorexant is superior to placebo as augmentation therapy with respect to change from baseline to Week 6 in the Montgomery Asberg Depression Rating Scale (MADRS) total score.

To evaluate the efficacy and safety of brexpiprazole as adjunctive treatment in elderly patients with Major Depressive Disorder (MDD)

In recent years, there has been growing evidence that antidepressants are only marginally effective compared to placebo for mild to moderate depression. In other words, although many people improve when they take antidepressant medications, almost as many get better with placebo pills. One possible solution to this problem would be to give patients a trail of a placebo prior to giving them an antidepressant, however there are ethical issues with doing this deceptively. New evidence from other placebo-responsive disorders such as irritable bowel syndrome shows that people may benefit from placebos even if they know they are taking them. This study aims to determine whether giving placebos without deception to people with major depressive disorder followed by the option to switch to an antidepressant is an effective strategy. There will be 3 groups of subjects. The first group is a standard treatment arm and will receive duloxetine, an antidepressant. The second will be given a placebo with the option to switch to duloxetine if they do not improve. The third group will receive supportive clinical visits the option to switch to duloxetine if they do not improve. This design will allow us to determine whether a sequenced treatment of a placebo without deception and then the option to switch to an antidepressant is a viable strategy. It will also help us to determine to what degree the benefit comes from the ritual of receiving and taking the placebo tablet versus the benefit of visits with a doctor alone. The primary hypothesis is that there will be a less than 5% difference between response rates after 12 weeks in the sequenced placebo-then-antidepressant treatment group (both subjects who have remained on placebo as well as those who have switched to the antidepressant will be considered as one group) compared to the immediate antidepressant therapy group.
