Imaging Depression in Parkinson's Disease
Recruiting
The goal of this observational study is to identify targetable neural substrates of depression in Parkinson's Disease for the first time in people with Parkinson's between the ages of 40 and 80, who are experiencing symptoms of depression.

PCORI Comparative Effectiveness Study-Esketamine (Spravato) vs. Ketamine-Equivalence Study
Recruiting
The purpose of this study is to compare the relative effectiveness, acceptability, and side effects of ketamine delivered through an IV (a drip into the arm) which is not currently FDA approved for use in the treatment of treatment-resistant depression (TRD) and Esketamine (Spravato®), taken as a nasal spray which has received FDA approval for use in the treatment of treatment-resistant depression (TRD) in the treatment of patients with treatment-resistant depression (TRD). The study will look a... Read More

Enhancing Week-long Psychological Treatment for PTSD With Ketamine
Recruiting
The purpose of this study is to test if the combination of ketamine, vs midazolam, with an intensive trauma-focused psychotherapy will be more effective in relieving post-traumatic stress disorder (PTSD). This week-long treatment has the potential to produce a significant therapeutic effect that otherwise would take months to occur. The study will also focus on learning about the neurophysiological changes produced by the proposed clinical trial.

The OBSERVE Protocol
Recruiting
This observational protocol is intended to provide long-term follow-up data on patients initiating or continuing treatment with either Spravato® or IV ketamine. This can provide us information on the patient acceptability and satisfaction, patterns of use, long-term effectiveness, and safety of the two approaches. This 5-year, 6-site study will enroll 450 total patients. The sites will comprise 3 academic medical centers and 3 community psychiatric practices.

Imaging SV2A in Mood Disorders
Recruiting
This study is designed to examine SV2A density in MDD and PTSD as a correlate of synaptic density, and to determine whether ketamine administration will reverse the synaptic loss in vivo in human subjects. To our knowledge, this is the first human study to examine SV2A in vivo in MDD and PTSD and to use the first known drug (ketamine) that rapidly reverses synaptic loss to determine whether ketamine administration could restore some of the structural changes associated with depression and PTSD....

Alpha-Amino-3-Hydroxy-5-Methyl-4- Isoxazole Propionic Acid Receptor Components of the Anti-Depressant Ketamine Response
Recruiting
The proposed study will assess the combined effect of perampanel and ketamine on the anti-depressant response in individuals with treatment resistant depression. The purpose of this study is to test the hypothesis that stimulation of Alpha-Amino-3-Hydroxy-5-Methyl-4- Isoxazole Propionic Acid receptors (AMPAR) is critical to the anti-depressant response of ketamine.

The Impact of AMPA Receptor Blockade on Ketamine's Anti-Suicidal Effects
Recruiting
The purpose of this study is to test the hypothesis that the anti-depressant and anti-suicidal effects of the N-methyl-D-aspartate receptor (NMDAR) antagonist Ketamine is critically dependent on stimulation of Alpha-Amino-3-Hydroxy-5-Methyl-4-Isoxazole Propionic Acid receptors (AMPAR).

Ketamine for the Treatment of Depression in Parkinson's Disease
Recruiting
The main purpose of this study is to examine the efficacy and safety of a repeated dosing ketamine infusion paradigm compared to placebo in individuals with PD. A subset of participants in each arm will undergo baseline and post-treatment PET and fMRI scans, to examine whether changes in synaptic density and reorganization of functional networks underlie ketamine's putative antidepressant effects in PD.
