HDWI High Grade Glioma Brain MRI

Condition: Neurological Disorders / Brain Tumors
Investigator: Tony J. Wang, MD
Status: Closed
The purpose of this study is to find out if performing Magnetic Resonance Image (MRI) scans of your brain with adaptive planning during your radiation treatment of your high-grade glioma will help determine how sensitive the images collected of the brain are at detecting the response of the tumor to the cancer treatment. In this study, four or seven MRI…

Study of Lutathera in Patients with Glioblastoma (GB)

Condition: Neurological Disorders / Brain Tumors
Investigator: Mikhail Doubrovin, MD
Status: Closed
The purpose of the study is to evaluate the safety of Lutathera alone in patients with recurrent glioblastoma and the combination of Lutathera with radiotherapy with temozolomide (TMZ) in patients with newly diagnosed glioblastoma (GB) and to establish the appropriate dose of this combination. Lutathera is a radioligand therapy, which is a targeted…

Study of Focused Ultrasound (FUS) with DEFINITY Microbubbles in Children and Young Adults with Progressive Diffuse Midline Glioma (DMG)

Condition: Neurological Disorders / Brain Tumors
Investigator: Stergios Zacharoulis, MD
Status: Closed
Children and young adults with diffuse midline glioma will be treated with Focused Ultrasound (FUS) with DEFINITY microbubbles and neuro-navigator-controlled sonication. The overall goal of this study is to see if the study treatment plan will improve the outcome of participants with diffuse midline glioma, for which no known cure exists, and determine…

Study of MTX110 in Combination with Gadolinium in Children with Newly Diagnosed Brain Cancer (Diffuse Midline Gliomas)

Condition: Neurological Disorders / Brain Tumors
Investigator: James Hinkley Garvin Jr, MD
Status: Closed
The purpose of this study is to find the best dose of a drug called MTX110 and a contrast agent called gadolinium that can be given safely in children with newly diagnosed diffuse midline gliomas, which is a kind of brain tumor. All patients enrolled in the study will receive infusion of MTX110 and Gadolinium delivered with a pump directly into the tumor…

Brain imaging in bipolar depression to understand the role of inflammation in its treatment.

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD, PhD
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…

Research Study offering Treatment for Self-Injury (Bipolar Disorder)

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.…

A Trial of Brexpiprazole and Sertraline in the Treatment of Post-Traumatic Stress Disorder

Condition: Psychiatric Disorders / PTSD
Investigator: Franklin Schneier, MD
Status: Closed
We are currently enrolling individuals with post-traumatic stress disorder (PTSD) to participate in this research study. The purpose of this research study is to evaluate the effectiveness of an investigational medication, brexpiprazole, for PTSD. Eligible participants will be randomly assigned to receive either brexpiprazole, sertraline (also known as…

Combined Prolonged Exposure and Pramipexole Treatment for Patients with PTSD and Depression

Condition: Psychiatric Disorders / PTSD
Investigator: Yuval Neria, PhD
Status: Closed
Approximately half of the individuals with Post-traumatic Stress Disorder (PTSD) present with major depressive disorder (MDD). Compared to PTSD alone, patients with comorbid PTSD-MDD demonstrate greater distress and poorer treatment outcome. The goal of this pilot study is to collect preliminary data on the feasibility, safety, and initial efficacy of an…

Brain imaging in bipolar depression to understand the antidepressant mechanism of lurasidone (Latuda).

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD, PhD
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,…

Visual Attention in PTSD (PTSD)

Condition: Psychiatric Disorders / PTSD
Investigator: Yuval Neria, PhD
Status: Closed
Emerging research has demonstrated a relationship between visual attention patterns and anxiety disorders, including PTSD. This study is designed to examine these visual attention patterns using eye-tracking A simple device that monitors eye-movements. The study included two sessions conducted approximately 1 week apart, each no longer than 1 hour. In both…

Lumateperone for the Treatment of Bipolar Disorder

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.…

MRI Effects of D-cycloserine & Lurasidone in Bipolar Depression

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…

Brain imaging in bipolar depression to be able to predict who will respond to antidepressant treatment

Condition: Psychiatric Disorders / Bipolar Disorder
Investigator: Martin Lan, MD, PhD
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…

DSC-MRI in Measuring Relative Cerebral Blood Volume for Early Response to Bevacizumab in Patients With Recurrent Glioblastoma

Condition: Neurological Disorders / Brain Tumors
Investigator: Angela Lignelli-Dipple, MD
Status: Closed
The purpose of this research study is to test whether the advanced perfusion MRI done prior to starting Bevacizumab and a few weeks after starting Bevacizumab can determine your response to the treatment better than the standard MRI performed at typical time points. The researchers want to see if this type of advanced MRI is better or the same as what is…
