Study of C2 CryoBalloon Focal Ablation System for Patients with Barrett's Esophagus

Condition: Gastrointestinal and Digestive Diseases / Barrett's Esophagus
Investigator: Julian Abrams, MD
Status: Currently Recruiting
This research study will look at a newer treatment option for Barrett's Esophagus (BE) which uses nitrous oxide to freeze unwanted tissue. The most commonly used treatment method is Radiofrequency Ablation (RFA) which uses heat to destroy the pre-cancerous tissue. Nitrous Oxide ablation using the C2 CryoBalloon Focal Ablation System, an FDA-cleared…

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…

A study for patients diagnosed with coronary artery disease using the SYNERGY Stent System

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.

A study for patients with Coronary Artery Disease (CAD) using the Orsiro Stent system

Condition: Heart Disease / Arterial Disease
Investigator: Michael Collins, MD
Status: Closed
This study is for patients with Coronary Artery Disease (CAD) and require a stent placement. The purpose of this clinical research study is to assess the safety and effectiveness of the Orsiro stent or a non-investigational Xience stent. The Orsiro stent is investigational, which means it is not yet approved by the FDA and can only be used in research…

A study for patients with aortic stenosis using new investigational device Evolut R

Condition: Heart Disease / Arterial Disease
Investigator: Susheel Kodali, MD
Status: Closed
The purpose of this research study, is to learn whether an experimental device (called Evolut R) can help clear hardened blockage in coronary arteries (blood vessels that feed the heart muscle) in patients with a disease is called aortic stenosis.Subjects that choose to participate and are eligible will have their interventional cardiologist use this device…

A study for patients with untreated dysplastic Barrett's Epithelium using the Coldplay CryoBallon Focal Ablation System

Condition: Gastrointestinal and Digestive Diseases / Barrett's Esophagus
Investigator: Julian Abrams, MD
Status: Closed
C2 Therapeutics is currently enrolling patients to participate in the Coldplay 3 clinical trial. Coldplay 3 is evaluating the effectiveness of the Coldplay CryoBalloon Focal Ablation System in patients with Barrett's esophagus who have not yet received treatment. Participants will undergo treatment with the Coldplay CryoBalloon Focal Ablation System…

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…

A study for patients with Barrett's esophagus using a Wide Area Transepithelial Sample Esophageal Biopsy (WATS) kits for analysis

Condition: Gastrointestinal and Digestive Diseases / Barrett's Esophagus
Investigator: Julian Abrams, MD
Status: Closed
The purpose of this study is to evaluate a new technique called Wide Area Transepithelial Sample 3-Dimensional Esophageal Biopsy (WATS) with computer assisted method of analysis of brush biopsy. This study will assess whether performing standard biopsies in addition to the WATS brush biopsies identifies more patients with dysplasia than does performing…

A follow-up survey for patients with Coronary artery disease who have received the Promus Premier drug eluting stent

Condition: Heart Disease / Arterial Disease
Investigator: Tamim Nazif, MD
Status: Closed
The purpose of this study is to survey patients who have undergone a percutaneous coronary intervention (PCI) at Columbia University Medical Center in which the physician used a stent called the Promus Premier stent. Patients will be asked to do a brief 15-30 minute survey regarding their health since the PCI and stent implantation.

Eradicating Barrett's Esophagus Using Radiofrequency Ablation or a Novel Hybrid Argon Plasma Coagulation Technique (BURN)

Condition: Gastrointestinal and Digestive Diseases / Barrett's Esophagus
Investigator: Julian Abrams, MD
Status: Closed
The purpose of the study is to compare two types of endoscopic treatments in patients with Barretts esophagus (BE) with abnormal cells (dysplasia); radiofrequency ablation (RFA) and hybrid argon plasma coagulation (H-APC). H-APC is a newer technique in the treatment of BE and has not been adequately studied and is not approved by the FDA for routine use.…
