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…
The objective of this study is to learn more about how safe and effective the Bare Temporary Spur Stent System is when used in patients who have blocked arteries in their lower limbs. The selection of subjects will be those with Critical Limb Ischemia (CLI), a form of Peripheral Arterial Disease (PAD) in which an artery (blood vessel) in the lower leg (…
The objective of the LIFE-BTK RCT is to evaluate the safety and efficacy of the ESPRIT BTK device (which is a bioresorbable polymeric scaffold with the everolimus drug and a bioresorbable polymeric coating mounted on a balloon dilatation catheter) compared to Percutaneous Transluminal Angioplasty (PTA), which is is a procedure that can open up a blocked…
A research team at Columbia University Irving Medical Center is collecting information for a registry studying how safely and effectively the ClotTriever device works in treating patients at least 18 years old with Deep Vein Thrombosis (DVT), or blood clots in the vessels of the leg. The sponsor of this study, Inari Medical, Inc., is paying the research…
Are you scheduled for an interventional vascular procedure, such as a Trans-catheter Aortic Valve Replacement (TAVR), Endovascular Aneurysm Repair (EVAR), Thoracic Endovascular Aortic Repair (TEVAR), or Balloon Aortic Valvuloplasty (BAV)? If yes, you may be eligible for this trial. This research trial studies the safety and efficacy of an Investigational…
The purpose of this study is to evaluate the safety and tolerability of study drug CCX168 when it is given to patients who are receiving the standard therapy for a certain type of vasculitis called ANCA-associated vasculitis (AAV). The study will also assess the effectiveness of the study drug, CCX168, in combination with the standard treatment of AAV. This…

Type B Aortic Dissection patients are being invited to take part in a research study of an investigational device. Bolton Medical, Inc., the company sponsoring this clinical trial, is studying an investigational device…
The purpose of this study is see if an experimental gene product, the Hepatocyte Growth Factor (HGF) Plasmid (AMG0001) which will be injected into the affected leg's muscles is effective in treating the blockages in your leg without causing adverse effects. Affected leg means the leg that has the severest disease relating to the blockage or narrowing…
Has your doctor determined that you have Peripheral Arterial Disease (PAD), and that an artery in your upper leg is blocked as a result? Is blood flow to your upper leg(s) blocked?This study will test the safety and effectiveness of the PQ Bypass System (two catheters called the DETOUR Crossing Device and the DETOUR Snare) in improving blood flow to your…
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…
All vascular repair and reconstruction surgery requires patching material. PhotoFix, made of cow heart membrane, is one of the FDA-approved patches on the market for use in vascular repair and reconstruction surgery. Other vascular patches on the market are also available and used by other surgeons for procedures like the one you need. This trial will study…
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…
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.…
