Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Reilly Kayser, MD
Status: Closed
The Center for OCD Research at Columbia University Irving Medical Center is seeking individuals with obsessive-compulsive disorder (OCD) to participate in a research study, at no cost to you. This study is investigating the medicinal effects of nabilone for OCD symptoms. Nabilone is a synthetic form of tetrahydrocannabinol (THC), which is one of the active…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Amy Rapp, PhD
Status: Closed
The goal of the project is to identify differences in learning in obsessive-compulsive disorder (OCD) by measuring the activity of the brain while participants complete computer tasks. Eligible participants will be asked questions about their medical and psychiatric history and perform tasks on a computer while an electroencephalogram (EEG) is recorded.…
Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD
Status: Closed
This is a research study to understand what causes bipolar disorder and how medications treat bipolar depression. Particularly, we are looking at the importance of inflammation in the process. If you participate, you will receive an experimental medication for your depression named ethyl eicosapentaenoic acid (ethyl EPA), an omega 3 fatty acid. You will…
Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Jeffrey Miller, MD
Status: Closed
The goal of this study is to examine how effective and well-tolerated a possible new treatment for individuals who injure themselves frequently will be. All research procedures can be done from home no in-person visits are required. We are studying a minimal-risk form of electrical brain stimulation called transcranial direct current stimulation, or tDCS.…
Condition: Lung Disease / Pulmonary Hypertension
Investigator: Erika Berman-Rosenzweig, MD
Status: Closed
This is a clinical research study designed to determine the safety and effectiveness of the TIVUS system, an investigational device used in the treatment of PAH. The TIVUS System is intended to treat patients with pulmonary artery hypertension by injuring the sympathetic nerves surrounding the pulmonary vasculature (denervation) using ultrasonic energy. The…
Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD
Status: Closed
We are trying to understand what causes bipolar disorder and how medications treat bipolar depression. If you participate, you will have two different brain scans (MRI and PET scan). You will also have antidepressant treatment for free. We will then be able to see whether information on the brain scans connects with how people do on the medications. The…
Condition: Lung Disease / Pulmonary Hypertension
Investigator: Elana Bernstein, MD
Status: Closed
This study involves two infusions of either rituximab or placebo, two right heart catheterizations (6 months apart), and a variety of other clinical study procedures and exams.
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Reilly Kayser, MD
Status: Closed
The Center for OCD and Related Disorders at New York State Psychiatric Institute/Columbia University Medical Center is seeking individuals aged 18+ with obsessive-compulsive disorder (OCD) to participate in a survey regarding their experiences with marijuana/cannabis. We hope this study will lead to increased understanding of how these substances affect…
Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD
Status: Closed
We are trying to understand what causes bipolar disorder and how medications treat bipolar depression. Particularly, we are looking at the importance of dopamine signaling in the process. If you participate, you will have two different brain scans (MRI and PET scan). You will also have treatment for your depression with an FDA approved medication,…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Helen Simpson, MD, PhD
Status: Closed
Eligible participants will be asked questions about their symptoms, complete questionnaires, and receive sessions of Cognitive-Behavioral therapy consisting of Exposure and Ritual Prevention (EX/RP) accompanied by the use of a mobile app. The purpose of this study is to assess whether the mobile app may be effective in improving symptoms of OCD.
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Pablo Goldberg, M.D.
Status: Closed
The purpose of this study is to assess the effects of a single infusion of ketamine for adolescents and young adults with obsessive-compulsive disorder (OCD). Ketamine is a FDA-approved anesthetic medication that can possibly cause a rapid decrease in OCD symptoms. To be eligible to participate, patients need to have already tried at least one SRI…
Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: David Hellerstein, MD
Status: Closed
This study is a double-blind and placebo-controlled study to assess its efficacy of the new drug Lumateperone for patients with Major Depressive Episodes associated with Bipolar I and Bipolar II disorder. Lumateperone is thought to exert its antidepressant effect through interaction with sereotogenic, dopaminergic, and glutamergic neurotransmitter targets.…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Helen Simpson, MD, PhD
Status: Closed
The purpose of this pilot research study is to test whether certain components of the marijuana plant, known as "cannabinoids", may help to reduce symptoms in patients with OCD. Specifically, patients enrolled in the study will smoke marijuana containing different concentrations of 2 different cannabinoids, THC and CBD. Both of these agents act on…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Helen Simpson, MD, PhD
Status: Closed
This study is investigating how the brains of people with OCD may change with treatment. The study uses Magnetic Resonance Imaging (MRI) to scan the brain, and the treatment used is a form of Cognitive-Behavioral therapy consisting of Exposure and Ritual Prevention (EX/RP). Participants will undergo a scan, which lasts for approximately 2 hours and takes…
Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Joshua Kantrowitz, Md
Status: Closed
We will evaluate the D-cycloserine (DCS) and lurasidone with MRI measurement of brain responses to DCS. DCS is a drug that works on the same brain receptor as ketamine. DCS is not approved by the FDA for bipolar depression. Study participants will receive a dose of lurasidone or placebo in one MRI and a dose of DCS in another, followed by an optional follow…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Yagna Pathak, PhD
Status: Closed
The study aims to assess the impact of repetitive transcranial magnetic stimulation (rTMS) on brain imaging and neurophysiological measures in patients with Obsessive-Compulsive Disorder (OCD).
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Helen Simpson, MD, PhD
Status: Closed
The Center for OCD and Related Disorders is currently conducting a study in treating Obsessive-compulsive Disorder (OCD), which is a severe illness characterized by distressing intrusive thoughts, images, or impulses about a variety of themes (e.g., fears of contamination or harm) and repetitive behaviors such as excessive washing or checking. The study is…
Condition: Lung Disease / Pulmonary Hypertension
Investigator: David Lederer, MD
Status: Closed
The purpose of this study is to study the effects of a new study drug known as Riociguat in people diagnosed with pulmonary hypertension (PH) associated with idiopathic interstitial pneumonia (IIP). Patients will be in the study for approximately 26 weeks in which they will take the pill Riogciguat three times a day.
