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…
Early Age-Related Hearing Loss Investigation (EARHLI) is a study to obtain information on how a hearing aid-based intervention can prevent cognitive decline in those at risk for Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD). Age-related hearing loss (ARHL) is the third most common chronic condition in older adults. The…
We are recruiting individuals and/or families with members under the age of 65 who have dementia or are experiencing memory problems. Our initial screening can be completed in person or over the phone. The evaluation will take about 1 to 1.5 hours per person and includes a: 1. Blood sample (5 tablespoons) or saliva (1 teaspoon) collection: These blood…
For over 30 years, The Columbia University Alzheimer's Disease Research Center (ADRC) has worked with thousands of participants who have helped provide important insights into how the brain ages and why Alzheimer's disease may develop. We are actively recruiting adults 65 years of age and older who share our commitment to be part of this…
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-…
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…
A significant focus of healthcare research is aimed at biomarker discoveries in brain and heart diseases in particular, and their impact on the human body in general. MRI is a key component in these healthcare services. It provides a non-invasive and non-ionizing approach to diagnose pathologies along with significant internal and external contrast…
This study is of a drug called CT1812, that is being evaluated as a possible treatment for Dementia with Lewy Bodies. In this study, which is carried out at multiple sites in the country, participants receive either CT1812 at one of two doses or placebo. The duration of the study is up to about 35 weeks. Participants receive blood tests, cerebrospinal fluid…
This is a research study for persons with memory problems that examines the utility of performing positron emission tomography (PET) scans for the brain amyloid protein found in Alzheimer's disease.
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…
Columbia Medical Center is recruiting for a study to test whether the drug oxytocin can improve symptoms of emotion and behavior (e.g. apathy) in people with frontotemporal dementia. The study will last for up to 24 weeks (6 months). This is a crossover study, which means that each participant will receive both oxytocin and placebo (medically inactive…
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.
Glaucoma is the leading cause of irreversible blindness worldwide. The most important test to detect progression is visual field testing. However, this test is very subjective, often unreliable, and variable. One of the main causes of unreliable tests is the lack of attentiveness or concentration during the test. Previous studies have shown that listening…
Glaucoma is a given name of a group of diseases that affect the retinal ganglion cells in the eye and the optic nerve. Glaucoma cause degeneration of the retinal ganglion cells in the retina and their projections (axons) that form the optic nerve. Retinal ganglion cells and their axons transmit all of our vision information from the eye to the brain through…
This is a 22-week treatment, multicenter, double-blind, placebo-controlled, parallel group, Phase 2 study to evaluate the efficacy, safety, and tolerability of the study drug E2027, in participants with Dementia with Lewy Bodies (DLB) Lewy Body Dementia - LBD. The main purpose of this research study is to find if a new drug called E2027 works in people who…
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 with Glaucoma. The purpose of this study is to investigate the safety and effectiveness of a study drug called Bimatoprost Sustained Release (SR) compared to treatment with eye drug Timolol. The Bimatoprost SR is an implant that is very small, is biodegradable (dissolves naturally in the body), and contains the bimatoprost drug.
