The objective of the study is to evaluate the safety and efficacy of the JenaValve Pericardial TAVR system when treating patients with aortic regurgitation. Aortic Regurgitation is a condition that develops when the heart's aortic valve does close tightly, therefore the blood leaks back into the heart chamber. The JenaValve Pericardial TAVR system will…
My Hand Project for Stroke Patients: We are testing a robotic device to help people who had a stroke use their weak hand more easily. This research study would involve you wearing a hand robot that helps open and close your fingers in order to use your hand to pick up common everyday objects. During the study, you may be asked to try out different…
The high incidence and variety of conduction disturbances post-TAVR represents a major challenge in the periprocedural management of TAVR recipients. Despite the growing body of knowledge on this topic, the large variability in the management of these complications has translated into a high degree of uncertainty regarding the most appropriate treatment of…
This prospective, multicenter trial is looking at the investigative device called the ACURATE Transcatheter Aortic Valve System for TAVR to see if it is safe and effective in treating patients with severe symptomatic native aortic stenosis. The ACURATE Transcatheter Aortic Valve System for TAVR is designed for iliofemoral access and delivery of a self-…
The purpose of this study is to determine if the use of immunotherapy nivolumab and the targeted therapy cabozantinib prior to removal of the kidney will increase the number subjects who are without any visible kidney cancer in their body at some point during the course of treatment. The study will also evaluate the changes that nivolumab and cabozantinib…
The purpose of this study is to study two experimental drugs called canakinumab and spartalizumab produced by Novartis to see if: It is safe and feasible to give canakinumab and spartalizumab prior to radical nephrectomy; canakinumab and spartalizumab can kill cancer cells and bring immune cells into the kidney cancer when given to human subjects prior to…
Aortic stenosis (AS) or narrowing of the arteries remains one of the most common valvular diseases in the Western population requiring intervention. The deterioration of the aortic valve is more common in the older population and usually along with coronary artery disease (CAD) requires the need for treatment. This is a study that is collecting safety and…
This program aims to help improve adult caregivers of stroke survivors ability to care for their stroke survivors with their daily needs. Each session will cover different topics which are important for caregivers to understand in order to best engage in their new role. Topics will include, but are not limited to: bathing, toileting, dressing, transfers,…
The purpose of this research is to learn about types of practice that may benefit stroke survivors when learning to use their weaker arm to perform a task. Potential participants will be asked to come to Columbia University Irving Medical Center (CUIMC) for a screening session. Eligible participants will be randomized into two groups with different practice…
This is a prospective, multicenter, non-randomized, single-arm, open-label clinical study, sponsored by Pi-Cardia. Fifteen (15) patients with symptomatic severe Aortic Stenosis (narrowing of the aortic valve) who are considered operable but are not recommended by the heart team for immediate treatment with surgical or transcatheter aortic valve replacement…
The study is to determine whether aortic valve replacement is helpful for patients who have moderate-severe, calcific, aortic stenosis (a narrowing of the aortic heart valve, where calcium has attached to the valve surface, resulting in obstructed blood flow) and do not have symptoms. Subjects will be randomly assigned, l to one of two groups: (1) Treatment…
Axitinib (AG-013736) is an investigational (experimental) drug that is being studied in patients with metastatic pheochromocytoma/paraganglioma. The main goal of this study is to find out if axitinib is able to stop tumors from growing, or shrink tumors in patients with this type of cancer.
This research study is a phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational treatment to learn whether the intervention works in treating a specific disease. Investigational means that the intervention is being studied. The Food and Drug Administration (FDA) has approved Nivolumab as treatment for…
The study is to determine whether aortic valve replacement is helpful for patients who have severe, calcific, aortic stenosis (a narrowing of the aortic heart valve, where calcium has attached to the valve surface, resulting in obstructed blood flow) and do not have symptoms.
This study will test whether cabozantinib in combination with nivolumab plus ipilimumab is more effective (works better) than nivolumab plus ipilimumab alone in treating patients with advanced kidney cancer who have not received prior treatment for their cancer. This study will also examine how safe cabozantinib is in combination with nivolumab plus…
The Amulet IDE trial is a prospective, randomized, multi-center active control worldwide trial, designed to evaluate the safety and effectiveness of the AMPLATZER Amulet Left Atrial Appendage Occluder. Subjects will be randomized in a 1:1 ratio between the Amulet LAA occlusion device (treatment) or a Boston Scientific WATCHMAN LAA closure device (Control).…
We are looking for adults who have had a stroke to participate in testing of a new robotic device for the hand. If you had a stroke over six months ago and now have difficulty using your hand, you may qualify to participate in this study. Time commitment: ~4 weeks, 3x/week, Compensation: $50 per testing visit, $25 per training session.
Stroke often results in limitation of arm movements, from which many people do not fully recover. We believe that early and intensive therapy is important to enhance recovery of arm movements after stroke. We are doing this research study to see how much arm movements improve with intensive therapy in patients have had a stroke in the past 5 weeks. We will…
We are doing this study to test a drug called MGD009. MGD009 is like an antibody, which is a protein in your blood that helps get rid of germs in your body. MGD009 is made to attach to cancer cells and to T-cells, which are a part of your immune system. Certain T cells have the ability to kill other cells, including cancer cells. By attaching to cancer…
The objective of this study is to collect outcome data on valve performance and a pre-specified TAVR care pathway. Transcatheter aortic valve replacement (TAVR) has been shown to be a safe and effective treatment for patients with severe aortic stenosis who are at extreme, high, or intermediate surgical risk. Since CoreValveTM became commercially approved…
This study is for patients who have renal cell carcinoma (RCC; a type of kidney cancer) and are at a high risk of disease coming back (disease recurrence) following either nephrectomy (surgical procedure to remove all or part of a kidney) or metastasectomy (removal of cancerous growth that has spread away from your kidney). The purpose of this study is to…
