Safety and Efficacy Study of Transcatheter Closure of Ostium Secundum Atrial Septal Defects (ASDs)

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…

MRI Study Comparing Medications for Children Ages 6-17 with ADHD

Condition: Psychiatric Disorders / ADD/ADHD
Investigator: Jonathan Posner, MD
Status: Closed
Children with Attention-Deficit/Hyperactivity Disorder (ADHD) are typically treated with two types of medications: stimulants and non-stimulants. These medications work in different ways to treat ADHD symptoms, but we do not fully understand the brain mechanisms underlying the medications' effects. This study will use MRI scanning to look at changes in…

A study for patients with Type 2 Diabetes Mellitus with coronary artery disease using study drug Ticagrelor

Condition: Heart Disease / Arterial Disease
Investigator: Melvin Weiss, MD, FACC
Status: Closed
The purpose of this study is to see if a new medication called ticagrelor given twice daily ismore effective than aspirin alone in preventing the occurrence of heart attack, stroke and/ordeath due to cardiovascular events in patients who have type 2 diabetes. Ticagrelor is anantiplatelet therapy (stop platelets from clumping together) and is approved for…
