All Clinical Trials

Columbia University Medical Center is conducting a pilot clinical research study that will assess the use of the medication metformin for heart failure in patients who are not diabetic and have no evidence of insulin resistance. Patients will received either the study drug metformin or placebo for 4 months. During the study, the patients will undergo extensive testing that will include symptom assesment, exercise capacity, echocardiography, cardiac PET imaging and blood tests. Read Less

The goal of this study is to determine the genetic basis of polycystic ovary syndrome (PCOS). We will first look for genes in the Icelandic population, where large family trees are known and it is easier to search for genes. We will then determine whether these same genes are important in U.S. PCOS patients. Read Less

While advancements in cardiac magnetic resonance (CMR) have improved image quality, it is unclear how these improvements are connected to the clinical evaluation of individuals with cardiovascular disease. The aim of this large prospective registry revolves around 4 key principles: 1) utilize CMR to gain additional pathophysiologic insights into cardiovascular disease, 2) understand how CMR compares to alternative cardiovascular diagnostic modalities, 3) determine how CMR affects clinical management decisions, and 4) establish a link between CMR findings and long term prognosis in patients with known or suspected cardiovascular disease. The ultimate aim is to utilize CMR to improve patient outcomes. CMR techniques to be studies include function, fibrosis, and flow. Focus areas include valvular heart disease, ischemic heart disease, cardiomyopathies, and vascular disease. Read Less

This is a prospective, observational study designed to describe disease progression, symptom change, quality of life, diet and lifestyle habits, and frequency of adverse events among patients with multiple sclerosis (MS) who use complementary and alternative medicine (CAM). In addition to describing the patterns of CAM use, this study will also identify and describe the positive deviants, those individuals with the highest quality of life and least amount of disease activity. Positive deviants will be compared to controls in order to describe medication, diet, and lifestyle patterns associated with a lack of MS disease progression and high quality of life. Read Less

Local injection of 5-fluorouracil into a chalazion (stye) is as effective as local injection of triamcinolone (steroid) and incision and curettage for treatment of chalazia. Read Less

This is a mechanistic clinical trial with randomization to guidance for the CRT procedure using cardiac magnetic resonance (CMR) and computed tomography angiography (CTA) versus a standard procedure. Read Less

To develop a tissue bank library for patients with parathyroid disease who have undergone surgery and/or biopsy, and/or who may undergo surgical intervention at M. D. Anderson Cancer Center or outside centers, and/or all patients seen through the Parathyroid Center at participating sites, whether or not the patients undergo treatment for their disease. The tissue bank will contain both normal parathyroid tissue and diseased tissue, and will provide a resource for the ongoing study of parathyroid disease and management. Read Less

The Biorepository for Caris Life Sciences is designed for the purpose of making quality biospecimens and associated clinical data available for research studies related to advancing precision medicine and improving care for patients. The Caris Biorepository is a repository of prospectively collected biological specimens and associated clinical and demographic data gathered from multiple sources to be stored, used and shared for research. Caris Life Sciences will maintain the data and specimens and will control access to and use of the information and specimens by multiple individuals for multiple purposes which may evolve over time.

To evaluate the safety and ocular efficacy of Dextenza in combination with an intracameral antibiotic and NSAID in controlling post-operative ocular pain and inflammation compared to standard of care topical therapy in patients undergoing bilateral cataract surgery. Read Less

The objective of this trial is to assess the safety and effectiveness of the study device in subjects with degenerative mitral valve disease receiving a mitral valve repair without cardiopulmonary bypass (treatment group) when compared to subjects receiving mitral valve repair using standard surgical techniques with cardiopulmonary bypass (control group).

The purpose of this study is to evaluate the feasibility of a fetoscopic surgical technique for antenatal correction of fetal myelomeningocele. Two surgical approaches will be utilized. The percutaneous approach will be offered to participants with a posterior placenta. The laparotomy/uterine exteriorization approach will be offered to participants regardless of placental location.

A protocol was developed to improve pregnancy results after IVM compared to results from studies in the literature. Differences from most published protocols include the use of the Steiner-Tan needle to optimize oocyte environment during oocyte retrieval, use of oral medications and very low doses of FSH, and delayed embryo transfer during subsequent warmed cryo-preserved embryo transfer. Eligible patient have a PCO pattern in their ovaries during transvaginal ultrasound. Read Less
