This study is for individuals who have Cushings disease and want to join voluntarily in this study to find out if a study drug called osilodrostat (LCI699) is safe and has beneficial effects in people who have Cushings disease. Cushings disease is a rare but debilitating disease. Cushings disease is caused by a benign tumor of the pituitary gland. The tumor…
The purpose of these studies is to gain an understanding of the mechanisms that promote weight loss and improved glucose control. The ultimate goal is to identify therapeutic pathways for obesity and diabetes as a way to optimize surgical procedures and discover novel non-surgical targets for safe and effective drug therapy. Participants with obesity will…
We are recruiting healthy volunteers, aged 18-65, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to induce temporary insulin resistance in 10-12…
The purpose of this study is to determine the safety and long-term effects of CK-3773274 and to learn how well it is tolerated at different, increasing dose levels in participants with HCM.
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…
This prospective, multicenter, open-label, single arm, first-in human study will enroll up to 75 subjects aimed at examining the performance of the LAAC device for LAA closure.
This is a research study for subjects who have had gastric bypass surgery at least one year ago, and currently have type 2 diabetes. This study is looking at the treatment of diabetes after gastric bypass surgery. About 40% of patients do not experience diabetes remission after gastric bypass surgery. Of the patients who initially go into remission, about…
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.
The purpose of this study is to evaluate the Biosensors BioFreedom Biolimus A9 Drug Coated Coronary Stent on people with coronary artery disease (blockages in the heart arteries) to determine if it is safe and effective.
The purpose of this study is to compare the effect of the investigational drug, Mavacamten, to a placebo (an inactive drug). This is being done to evaluate whether Mavacamten is safe in obstructive Hypertrophic Cardiomyopathy (HCM) patients and helps to improve symptoms or ability to exercise. Mavacamten is an investigational drug. This means that it has…
The purpose of this study is to investigate how well weekly injections of the growth hormone drug NNC0195-0092 works in adults with growth hormone deficiency. Growth hormone deficiency is a disorder that involves the pituitary gland (a small gland located at the base of the brain). The gland produces growth hormone and other hormones (chemical messengers of…
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.
Polycystic ovary syndrome (PCOS) is a common disorder. Young women with PCOS have irregular or absence of menstruation and excessive acne and or hair on their bodies. They may have multiple cysts on their ovaries. Adolescents and women affected with PCOS are at risk of developing abnormalities in their blood including high fat, low HDL cholesterol (good…
