Active clinical trials for "Depressive Disorder, Treatment-Resistant"

The purpose of the study aims to determine whether different concentrations of nitrous oxide (N2O) have different antidepressant effects for adults with treatment-resistant major depression.

The purpose of this study is to evaluate the efficacy of switching adult participants with treatment-resistant depression (TRD) from a prior antidepressant treatment (to which they have not responded) to flexibly dosed intranasal esketamine (56 milligram [mg] or 84 mg) plus a newly initiated oral antidepressant compared with switching to a newly initiated oral antidepressant (active comparator) plus intranasal placebo, in improving depressive symptoms. Efficacy will be assessed by the change from baseline in the Montgomery Asberg Depression Rating Scale (MADRS) total score from Day 1 (before randomization) to the end of the 4-week double-blind treatment phase.

The purpose of the study is to determine the efficacy, safety and pharmacokinetics of inhaled Esketamine in participants with treatment-resistant depression (TRD) in the course of Major Depressive Disorder (MDD). The study is to determine the efficacy and dose response of three Esketamine doses, compared with placebo.

This a Phase 2a, multicenter, randomized, double-blind, placebo controlled 3 arm study to assess the safety and tolerability of multiple oral doses of REL-1017 25 mg and 50 mg as adjunctive therapy in the treatment of patients diagnosed with major depressive disorder (MDD). The patients will be adults with MDD who are diagnosed with a current MDE who have experienced an inadequate response to 1 to 3 courses of treatment with an antidepressant medication. This population will provide the opportunity to compare the safety and efficacy effects of treatment with an approved antidepressant in conjunction with REL-1017 versus the effects of an antidepressant alone. This study includes in-patient and out-patient periods.

It's a prospective, multicentric, randomized, controlled study concerning 56 patients with treatment-resistant depression (TRD). The main objective of this study was to evaluate the efficacy of priming repeated Transcranial Magnetic Stimulation (rTMS) sessions before Electroconvulsive therapy (ECT) for treatment of TRD patients. The primary outcome will be the depressive symptoms intensity measured with the Hamilton Rating Scale For Depression (HAMD-21 items) after 5 ECT. The secondary outcome is to evaluate the safety and most particularly the cognitive effects of this association.

This study is a multi-center, open-label trial to evaluate the long-term safety and efficacy of AXS-05 in subjects with treatment resistant depression (TRD) and major depressive disorder (MDD).

The purpose of this study is to assess the impact of music on patients receiving a course of intravenous (IV) ketamine for treatment-resistant depression (TRD), both unipolar and bipolar. The primary outcome is changes in in systolic blood pressure throughout each 40-minute infusion. Secondary outcomes include repeated measures of mood, anxiety, suicidality, and psychological/physical pain. Aspects of the treatment experience, with and without music, will also be explored.

This study aims to examine the antidepressant efficacy of riluzole, employing a randomized, double-blind, placebo-controlled, adjunctive trial in treatment-resistant major depressive disorder (TRD).

This study will use a randomized parallel group design to examine the effects of Intensive Short-term Dynamic Psychotherapy (ISTDP) for depressed patients non-remitting following at least one course of antidepressants. The effects of ISTDP will be judged through comparison against secondary care treatment as usual. The aim is to establish the clinical and cost effectiveness of ISTDP treatment.

Atypical neuroleptics may have antidepressant qualities in bipolar depression and in unipolar depression. Some data support the use of both Risperidone and Olanzapine, but there are no direct comparisons of their relative efficacy and tolerability in treatment resistant depression. The current study was designed as a pilot study to examine efficacy and tolerability of Olanzapine vs. Risperidone add on to a failed serotonin re-uptake inhibitor (SSRI) in depression.
