A Prospective, Single-Arm, Multicenter Study to Investigate the Safety and Effectiveness of SAPIEN 3/SAPIEN 3 Ultra Transcatheter Heart Valve Implantation in Patients With a Failing Aortic Bioprosthetic ValveThis study will evaluate the safety and effectiveness of the Edwards SAPIEN 3 Transcatheter Heart Valve (THV) Model 9600TFX and associated delivery systems for the aortic valve in valve procedure.
Participants in this study will have the investigational (experimental) Edwards SAPIEN 3 transcatheter aortic heart valve (study device) to replace … This study will evaluate the safety and effectiveness of the Edwards SAPIEN 3 Transcatheter Heart Valve (THV) Model 9600TFX and associated delivery systems for the aortic valve in valve procedure.
Participants in this study will have the investigational (experimental) Edwards SAPIEN 3 transcatheter aortic heart valve (study device) to replace the failing bioprosthetic aortic valve access through the heart through a small incision is in the chest.
The study device and its delivery system are investigational, which means they are not approved for commercial use by the U.S. Food and Drug Administration (FDA) for the valve in bioprosthetic valve procedure. The previous generation of SAPIEN valves, SAPIEN XT, was approved for commercial use by the FDA for a failed surgical bioprosthetic aortic valve in October 2015.
The study device is a bioprosthetic heart valve made out of man-made materials and animal tissue. It is an artificial device made to replace the diseased aortic heart valve. Each valve consists of a stent (mesh tube made of metal) to hold the study device in its intended position and valve leaflets (made of biological material derived from cows) to direct the flow of blood in the heart.
Study participation will last approximately 10 years. Participants will be asked to come to clinic for study visits at 30 days, 6 months, and 12 months after the study procedure and then annually until 10 years after the procedure.
We expect up to 19 people will be enrolled at Northwestern. The study expects to enroll up to 125 people internationally. |
Clinical Study of the Edwards Cardioband™ Tricuspid Valve Reconstruction SystemThis study is recruiting patients with tricuspid regurgitation (a condition in which blood flow through the tricuspid valve of the heart flows in the wrong direction) that may benefit from a new tricuspid valve reconstruction system. This is an early feasibility clinical research study that will evaluate the safety and … This study is recruiting patients with tricuspid regurgitation (a condition in which blood flow through the tricuspid valve of the heart flows in the wrong direction) that may benefit from a new tricuspid valve reconstruction system. This is an early feasibility clinical research study that will evaluate the safety and performance of the Edwards Cardioband Tricuspid Valve Reconstruction System, (the “Study Device” ).
The Study Device includes an adjustable implant that is delivered and anchored to the tricuspid valve by a transfemoral delivery system, meaning it is inserted in a minimally invasive procedure through a puncture into a vein in the leg. The Cardioband Implant will be positioned around the tricuspid valve and will be adjusted to reduce the size of the valve, thus improving the tricuspid regurgitation.
Up to 15 patients will be enrolled in this study at up to 15 sites. All enrolled study patients will be assessed at the following intervals: screening/baseline, procedure, discharge, 1 month, 6 months, 1 year and annually for 5 years post implant procedure. |

Transcatheter Aortic Valve Replacement to UNload the Left ventricle in patients with ADvanced heart failure: a randomized trial (TAVR UNLOAD)The purpose of this study is to evaluate the use of a device to treat patients with Heart Failure (HF - inability of the heart to pump enough blood to meet the body's needs) who have moderate aortic stenosis (AS - narrowing of the aortic valve resulting in obstructed blood flow). … The purpose of this study is to evaluate the use of a device to treat patients with Heart Failure (HF - inability of the heart to pump enough blood to meet the body's needs) who have moderate aortic stenosis (AS - narrowing of the aortic valve resulting in obstructed blood flow). This clinical trial is comparing the safety and effectiveness of TAVR (Transcatheter Aortic Valve Replacement) with the Edwards SAPIEN 3 Transcatheter Heart Valve (the Study Valve) and OHFT (optimal heart failure therapy) versus OHFT alone in HF patients with moderate AS. The study valve has not been approved by the U.S. Food and Drug Administration (FDA) for use in this patient population, and therefore it's use in this study is considered investigational. This study is looking for patients with Heart Failure and moderate Aortic Stenosis. Aortic Stenosis is a narrowing of the aortic valve opening,which blocks blood flow from the heart and causes symptoms such as chest pain,fainting and shortness of breath.

Right Ventricular Ischemia and Fibrosis in Chronic Thromboembolic Pulmonary Hypertension (CTEPH)This study is enrolling patients who have been diagnosed with chronic thromboembolic pulmonary hypertension (CTEPH) and who are scheduled for a pulmonary endareterectomy (PEA) or balloon pulmonary angioplasty (BPA) procedure for treatment. CTEPH is high blood pressure in the arteries in the pulmonary system (lungs) caused by clots. Over time … This study is enrolling patients who have been diagnosed with chronic thromboembolic pulmonary hypertension (CTEPH) and who are scheduled for a pulmonary endareterectomy (PEA) or balloon pulmonary angioplasty (BPA) procedure for treatment. CTEPH is high blood pressure in the arteries in the pulmonary system (lungs) caused by clots. Over time the clots typically leave scar tissue (fibrosis) in the arteries and lead to poor blood supply to the heart. In patients with CTEPH symptoms of heart failure commonly result from dysfunction (not working correctly) in the right ventricle (RV), or the chamber of the heart that pumps blood to the lungs. However, little is currently known about why or how that chamber of the heart becomes dysfunctional in patients with this condition. In another chamber of the heart, the left ventricle, it is known that elevated blood pressure in that chamber causes the development of diffuse fibrosis, or scarring between the muscle fibers, and a similar process may take place in the right ventricle of patients with CTEPH. For this study a cardiac magnetic resonance imaging (MRI) stress test (also known as stress CMR) will be done to look at the RV in patients with CTEPH before and 6 months after treatment. A stress CMR is a specialized scan of the heart that examines fibrosis (scarring) and blood flow (perfusion) both at rest and under stress. A gadolinium contrast agent (MRI dye) is given to highlight the heart muscle in areas receiving a good blood supply. Areas receiving less blood do not highlight as well as the good areas, which can be an indicator of ischemic heart disease (undersupply of blood and oxygen to the heart). |
Percutaneous MitraClipTM Device or Surgical Mitral Valve REpair in PAtients with PrImaRy Mitral Regurgitation who are Candidates for Surgery (REPAIR MR)The purpose of this research study is to compare health outcomes of patients diagnosed with Primary MR who have their MV repaired with open heart surgery, which is the current standard treatment, to patients who have their Mitral Valve repaired with the MitraClip System. The MitraClip System uses a less … The purpose of this research study is to compare health outcomes of patients diagnosed with Primary MR who have their MV repaired with open heart surgery, which is the current standard treatment, to patients who have their Mitral Valve repaired with the MitraClip System. The MitraClip System uses a less invasive procedure to repair the mitral valve. Subjects are asked to participate in this Study because they have moderate-to-severe or severe MR and it has been determined to have symptoms due to heart failure despite being treated with currently available therapies. MR occurs when the leaflets of the mitral valve do not close properly causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart needs to pump more blood with each beat to push the same amount of blood forward. The Study will enroll approximately 500 subjects at up to 60 sites in Europe, United States, and Canada. The Study consists of two arms: Device Arm and Control Arm.

A Multi-Center, Randomized, Double-blind, Placebo-controlled, Dose-finding Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of CK3773274 in Adults with Symptomatic Hypertrophic CardiomyopathyThis study is enrolling patients who have obstructive hypertrophic cardiomyopathy (oHCM). Obstructive HCM is a condition in which the heart muscle in the left ventricle (LV) becomes abnormally thickened, which can block blood flow out of the heart to the body. This obstruction causes the LV heart muscle to work … This study is enrolling patients who have obstructive hypertrophic cardiomyopathy (oHCM). Obstructive HCM is a condition in which the heart muscle in the left ventricle (LV) becomes abnormally thickened, which can block blood flow out of the heart to the body. This obstruction causes the LV heart muscle to work harder to pump blood to the body and can cause symptoms of chest pain, dizziness, shortness of breath and fainting. This is the first time the investigational drug called CK-3773274 is being studied in participants who have oHCM, but it has already been studied in healthy volunteers. The purpose of this study is to learn how well CK-3773274 is tolerated at different, increasing dose levels in patients with oHCM and if it causes any side effects. The study will also measure the amount of CK-3773274 in your blood at various times, and the effect the study drug may have on your oHCM. CK-3773274 is an investigational (experimental) study drug. This means that CK-3773274 has not been approved by the U.S. Food and Drug Administration (FDA) for use outside of a research study. |
A Phase 3 Global, Double-Blind, Randomized, Placebo‑Controlled Study to Evaluate the Efficacy and Safety of ION-682884 in Patients with Transthyretin‑Mediated Amyloid Cardiomyopathy (ATTR CM)This study is enrolling patients who have transthyretin-mediated amyloid cardiomyopathy (ATTR-CM) which is a disease caused by change in a protein called transthyretin (TTR). This change can either be sporadic which is known as wild-type (wtATTR-CM) or due to a mutation of the TTR gene which … This study is enrolling patients who have transthyretin-mediated amyloid cardiomyopathy (ATTR-CM) which is a disease caused by change in a protein called transthyretin (TTR). This change can either be sporadic which is known as wild-type (wtATTR-CM) or due to a mutation of the TTR gene which is hereditary (hATTR-CM). In both cases, these changes can cause the TTR to clump and build up in certain parts of the body such as the nervous system, stomach, intestines, and heart. This build up is called an amyloid deposit. Amyloid deposits can sometimes cause heart disease or neuropathy (nerve damage). When amyloid is deposited into the heart, it can result in a condition referred to as cardiomyopathy. ION-682884 is an investigational drug. “Investigational” means that ION-682884 is not yet approved for use in any settings outside of clinical research studies like this one and is considered experimental. ION-682884 reduces the level of TTR in the blood of animals and healthy volunteers tested to date. Reducing the amount of TTR in the blood may reduce the amount of amyloid deposits in the body and may keep cardiomyopathy from getting worse over time. However, it is not known if ION-682884 will help cardiomyopathy. The purpose of this study is to evaluate the safety of ION-682884 and determine if it can help people with this type of cardiomyopathy. |
Targeting Inflammation and Alloimmunity in Heart Transplant Recipients with TocilizumabThis study is enrolling patients who are about to have a heart transplant. After transplantation, or any other major surgery, there will be inflammation in the body. This inflammation can contribute to rejection of the transplanted heart. In addition, the immune system (your body’s defenses to protect against disease) … This study is enrolling patients who are about to have a heart transplant. After transplantation, or any other major surgery, there will be inflammation in the body. This inflammation can contribute to rejection of the transplanted heart. In addition, the immune system (your body’s defenses to protect against disease) will be activated by the presence of the new heart. Investigators believe that a drug called tocilizumab (ACTEMRA®) might reduce or prevent inflammation and reduce the immune system’s response to the new heart, and that this would improve the long-term health of your new heart. The purpose of this research study is to see if a study drug called Actemra® (tocilizumab) will, when given with standard anti-rejection medicines, lead to better heart transplantation outcomes at 1 year after the transplant. Tocilizumab is a prescription medicine approved by the US Food and Drug Administration (FDA) to treat rheumatoid arthritis (RA) and other inflammatory diseases. Tocilizumab has not been used before to treat people who receive a heart transplant. We don’t know if it will be good for people who have a heart transplant. Tocilizumab is not approved by the FDA to treat heart transplant patients, and therefore using it in this study is considered investigational. |
Edwards EVOQUE Transcatheter Tricuspid Valve Replacement: Pivotal Clinical Investigation of Safety and Clinical Efficacy using a Novel DeviceThis study is recruiting patients with Tricuspid Regurgitation (TR), a condition in which the heart’s tricuspid valve does not close tightly which causes the blood to flow in the wrong direction during part of the cardiac cycle (heart beat). This condition increases the workload on the heart and if … This study is recruiting patients with Tricuspid Regurgitation (TR), a condition in which the heart’s tricuspid valve does not close tightly which causes the blood to flow in the wrong direction during part of the cardiac cycle (heart beat). This condition increases the workload on the heart and if left untreated, it can increase the risk of worsening heart failure. The goal of this trial is to evaluate the safety and effectiveness of the Study Device with Optimal Medical Therapy (OMT) compared to OMT alone in the study of subjects with severe or greater tricuspid regurgitation. |
iCLAS™ for Persistent Atrial FibrillationThis study is enrolling patients who have an irregular heartbeat(arrhythmia) and have been scheduled for an ablation (procedure that destroys small area of heart tissue that causes an arrhythmia) to treat the arrhythmia. This irregular heart rhythm is also known as atrial fibrillation, or AF. There are several forms … This study is enrolling patients who have an irregular heartbeat(arrhythmia) and have been scheduled for an ablation (procedure that destroys small area of heart tissue that causes an arrhythmia) to treat the arrhythmia. This irregular heart rhythm is also known as atrial fibrillation, or AF. There are several forms of AF. Persistent AF is when the irregular heart rate become continuous and lasts for at least 7-days but no more than 12 months. Once it has lasted continuously for more than one-year it is referred to as long-standing persistent AF. AF may be treated with medicines, electrical shock(cardioversion), or the ablation for which the patient has been scheduled. The purpose of this study is to demonstrate the safety and effectiveness of the Adagio Medical iCLAS System when used in the treatment of persistent atrial fibrillation. The device is a new type of ablation technology that uses very low freezing temperatures. |
