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…
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…
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.

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: 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…
Condition: Heart Disease / Arterial Disease
Investigator: Robert Sommer, MD
Status: Closed
This is a prospective, single arm, three stage, multi-site, clinical investigation evaluating the safety and efficacy of the Carag Bioresorbable Septal Occluder (CBSO) to treat patients with clinically significant hole in the atrial septal defect compared to other commercially approved devices. The study is being done to determine the safety and efficacy of…
Condition: Heart Disease / Arterial Disease
Investigator: Robert Sommer, MD
Status: Closed
This prospective, multicenter, open-label, single arm, first-in human study will enroll up to 75 subjects aimed at examining the performance of the LAAC device for LAA closure.
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: Heart Disease / Arterial Disease
Investigator: Kumar Kalapatapu, MD, FACC
Status: Closed
The purpose of this study is to evaluate the Biosensors BioFreedom Biolimus A9 Drug Coated Coronary Stent on people with coronary artery disease (blockages in the heart arteries) to determine if it is safe and effective.
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: 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…
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: Heart Disease / Arterial Disease
Investigator: Manish Parikh, MD
Status: Closed
The purpose of this research is to find out whether it is safe to shorten the length of time that people at high risk for bleeding take blood thinners after being treated with a coronary stent.
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Yagna Pathak, PhD
Status: Closed
