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

This study will determine the safety and efficacy of home administered tDCS in adults with unipolar depression. The device used to administer tDCS will be the Soterix Medical 1X1 mini-CT. 32 tDCS sessions of 30 minutes each will be delivered over 10 weeks.

This pilot study will assess the safety and feasibility of intravenous (IV) ketamine in older adults with Treatment-Resistant Depression (TRD). In addition, this study will develop and utilize innovative methodological approaches to demonstrate the feasibility of precision medicine and mobile health approaches in depression treatment.

Many patients with depression do not respond well to medication and are diagnosed with treatment refractory depression (TRD). Sometimes medications don't work because an individual metabolizes the drugs in an atypical manner (too fast/slow). Alternatively, drugs may fail to work because the underlying sub-type of depression is not effectively targeted by a medication. This study will use genetic testing of subjects with TRD to personalize the drug treatment of depression and guide the patient to a better clinical outcome. In the guided group, the clinician will receive a pharmacogenetic report to help individually tailor medication selection for TRD patients, potentially allowing the clinician to pick more effective medications right away, and when necessary, use drug combinations that are well-tolerated and less likely to cause unwanted side effects. The control group will receive a sham genetic report and be treated according to typical standards of care. The investigators will conduct our study in a "real world" setting, with few restrictions on which TRD patients can participate. In this way, the findings may be more likely to reveal how useful genetic testing will be when applied more broadly in psychiatry.

This study evaluates an accelerated schedule of theta-burst stimulation using a transcranial magnetic stimulation device for treatment-resistant depression. In a double-blind fashion, half the participants will receive accelerated theta-burst stimulation while half will receive sham treatment.

The goals of this study are: 1) to investigate the efficacy of combining ketamine with intensive cognitive behavioral therapy (CBT) to sustain the antidepressant effects of ketamine; and 2) to determine ketamine's delayed effects on learning and memory, and to explore the relationship between any ketamine-induced changes in learning and memory and duration of antidepressant efficacy, with and without CBT augmentation. Subjects with a diagnosis of MDD who are treatment-resistant to at least 2 antidepressants and have chosen to pursue clinical ketamine treatment at Yale Psychiatric Hospital will be recruited for the study.

The purpose of this study is to examine the effectiveness of a single infusion of ketamine (KET), to determine which dose is optimal 7 days after infusion using Bayesian Adaptive Randomization, and to learn about how ketamine works in the body and brain in persons with late-life treatment resistant depression.

This study will be an open-label 6-week (30 session) trial of active repetitive transcranial magnetic stimulation (rTMS) using a fixed frequency (10 Hz) but varying stimulation intensities using a 3+3 study design for safety and tolerability amongst adolescents. This means that we will only enroll 3 participants at a time and give them rTMS at the stimulation intensity energy of 80% of motor threshold (MT). If all three participants complete the 6 weeks of treatment with no major safety events (i.e. seizure), we will increase the energy for the next 3 participants by 20%. If 1 of the 3 participants has a major safety event, we will enroll 3 more patients at the SAME energy. We will proceed in this manner, increasing by 20% after 3 subjects safely complete treatment at that energy, to a maximum energy of 120% of motor threshold. If 2 participants in each intensity level cohort experience a major safety event, we will discontinue running subjects at that energy level. If this happens at our initial energy level of 80% of MT, we will stop the study. If we reach 2 events in any of the higher energy cohorts, we will return to the previous energy level and complete the remainder of the subjects at that energy level.

The purpose of this study is to compare the efficacy and safety of switching treatment-resistant depression (TRD) subjects from a prior antidepressant treatment (to which they have not responded) to either intranasal esketamine plus a new oral antidepressant or switching to a new oral antidepressant plus intranasal placebo.

The investigators hypothesize that the administration of two widely available, naturally occurring dietary supplements, 5 hydroxytryptophan and creatine monohydrate, will reduce the severity of depression in individuals exposed to chronic hypoxia by living at altitude. The purpose of this study is to determine if 8 weeks of dietary augmentation with oral 5 g creatine daily and 100 mg 5-HTP twice daily reduces hypoxia-related depressive symptoms measured by the 17-item Hamilton Depression Rating Scale (HAM-D) in women with SSRI or SNRI-resistant depression.

The objectives of this 10-week study are to evaluate the efficacy, safety, and tolerability of AVP 786 as an adjunctive therapy compared with placebo in patients with major depressive disorder (MDD) who have shown an inadequate response to standard antidepressant treatment. A secondary objective of this study is to assess the pharmacokinetics (PK) of AVP-786 and potential correlations with pharmacodynamic effects.
