Ketamine for Older Adults Pilot
Treatment Resistant DepressionRefractory Depression3 moreThis 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.

Home-administered tDCS for Treatment of Depression
Unipolar DepressionTreatment Resistant DepressionThis 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.

Pharmacogenetic Implementation Trial in Veterans With Treatment Refractory Depression
DepressionDepressive Disorder5 moreMany 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.

Cognitive Therapy to Sustain the Antidepressant Effects of Intravenous Ketamine in Treatment-resistant...
Depressive DisorderMajorThe 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.

Stanford Accelerated Intelligent Neuromodulation Therapy for Treatment-Resistant Depression (SAINT-TRD)...
Treatment Resistant DepressionThis 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.

Ketamine for Treatment Resistant Late-Life Depression
Treatment Resistant Depressive DisorderThe 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.

A Study to Evaluate the Efficacy, Safety, and Tolerability of Flexible Doses of Intranasal Esketamine...
Treatment-resistant DepressionThe 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.

Treatment Resistant Depression (Pilot)
Depressive DisorderTreatment-ResistantTreatment resistant depression (TRD) is a major public health problem. Current therapeutic options for this patient population remain limited. With all available treatments, only a sub-set of those patients who achieve an antidepressant response are likely to achieve treatment-induced remission. The need for antidepressant medication that can provide both rapid and long lasting relief of TRD symptoms is widely recognized. There is new evidence that drugs that block NMDA glutamate receptors (NMDA antagonists) are promising candidates for meeting this need. Existing studies in TRD have used only a low-dose, brief infusion of ketamine that would not be expected to re-sensitize the NMDA receptor; in agreement with this theory, these prior studies have found only temporary improvements of depression. Our key hypothesis is that a higher-dose, longer-term ketamine infusion, such as that used in chronic pain studies, would provide a more robust and lasting improvement from depression. Accordingly, we will test whether a 100-hour ketamine infusion would be more effective than the standard 40-minute ketamine infusion currently used in other TRD studies. We will randomize subjects to one of 2 arms: (1) 100-hour (+/- 4 hours) ketamine infusion plus clonidine for the entire infusion (2) 40-minute ketamine infusion (plus clonidine) following a 100+/- hour saline infusion. All subjects will receive clonidine, an alpha-2 agonist, to minimize side effects of ketamine (namely, brief/mild psychotic and cognitive symptoms).

Exercise in Treatment Resistant Depression (TRD): A Feasibility Study
Treatment Resistant DepressionThe objective of this study is to determine the effects of adjunct exercise in treatment resistant depression. The central hypothesis for the research is that adjunct exercise with usual care in Treatment Resistant Depression (TRD) will have significant effects in improving the psychiatric symptoms in comparison to usual care alone.

Pulsating ElectroMagnetive Treatment (PEMF) at Treatment Resistant Depression
Treatment Resistant DepressionIn this study patients with treatment resistant depression, as defined by Harold Sackeim, is subjected to daily sessions, for eight weeks, with Pulsating ElectroMagnetive Treatment (PEMF). Treatment is given two times a day, in the morning and in the afternoon. Patients are randomized into two groups. In group A patients receive active treatment both morning and afternoon. In group B patients receive one sham and one active treatment. The study is double-blind as neither the assessors or patients are aware of treatment allocation. Each session lasts 30 minutes. Patients are psychometrically assessed weekly for depression severity and side effect. After this intervention period patients are followed for further three weeks without PEMF treatment. Patients are on unchanged medication for the whole of the study period.
