Clinical Trials

The Bashir™ Endovascular Catheter has been designed to administer therapeutic agents in the peripheral vasculature. Because of the unique design of the catheter, with its six expandable infusion limbs, the Bashir™ Endovascular Catheter has the ability to: 1. Create a much larger central channel for blood flow, thereby utilizing the body's own endogenous fibrinolytic agents to lyse the clot, and 2. Greatly enhance the radial dispersion of a catheter-administered thrombolytic agent throughout the thrombus. Expansion of the multiple arms of the basket in the infusion catheter causes fissuring of the clot. The net result is that a greater surface area of clot is exposed to both endogenous and exogenously administered lytic agents, thereby promoting clot dissolution.

The purpose of this study is to determine the occurrence of scarring of the heart (cardiac fibrosis) and inflammation in those with perinatally acquired Human Immunodeficiency Virus (HIV) infection compared to people not infected with HIV. The information learned from this research may help the investigator to better understand the link between cardiac fibrosis and cardiac dysfunction and inflammation in those with perinatally acquired HIV infection compared to the uninfected.

This project will determine the health impact of parenthood on people with cystic fibrosis (CF). The study team will use retrospective data to provide relatively immediate evidence on parenthood's effect on pulmonary health.

The purpose of this study is to look at lung ventilation in people with cystic fibrosis over time (1 year) using magnetic resonance imaging (MRI) with an inhaled contrast gas, and compare these measures to lung function assessed by spirometry and multiple breath nitrogen washout. This study also looks at how these measures change in response to a pulmonary exacerbation and treatment (if applicable). Over the span of a year, participants would be asked to complete 3-5 visits to the University of North Carolina at Chapel Hill (UNC). with each lasting up to 4 hours. If participants do not have a pulmonary exacerbation during the year they would be asked to complete 3 visits (one at enrollment, a second roughly 2 weeks later, and the third approximately a year later). If participants do experience a CF pulmonary exacerbation they would complete 5 visits (Visit 1, Visit 2, two exacerbation visits with one before treatment and the other after, and Visit 3 at one year after Visit 1). Only one exacerbation per participant will be tracked. Participants are eligible for this study if they are 18 years old or older, have Cystic Fibrosis (CF) with mild lung disease (FEV1 >/= 60%), and can undergo an MRI. There are no known benefits for participating in this study.

Do you have overweight or obesity? Researchers are testing whether messages sent through a mobile app can help people lose weight. To participate, you must be 18 to 39 years and own a smartphone with a data and text messaging plan. The study is taking place in Chapel Hill, North Carolina.

Are you an adult with overweight or obesity? Researchers are studying a program that helps with physical activity. To join, you need a computer or smart phone and Wi-Fi. You must also be exercising less than 150 hours a week and not be in any weight loss or exercise programs. The study is in Aurora, Colorado.

Do you have asthma and obesity and live near Aurora, Colorado? Obesity can lead to widespread inflammation that may make asthma worse. This study will test whether a medicine called CXA-10 reduces inflammation in the airways and body and improves asthma symptoms in people who have obesity. To participate in this study, you must be between 18 and 65 years old, have a BMI of 30 or greater, and have been on long-acting controller medicine—such as inhaled corticosteroids or long-acting beta2-agonists—for at least three months. This study is located in Aurora, Colorado.

Are you an adult with both asthma and obesity? This study is testing whether a medicine called L-citrulline can help treat asthma and improve lung function in people who have obesity. To participate in this study, you must be 18 to 65 years old and have asthma and obesity. This study takes place in Durham, North Carolina.

Are you an adult who has overweight or obesity and would be interested in a weight-loss study? This study is testing whether a medicine called phentermine is safe and effective for treating obesity over a long period. This study has multiple locations in the United States.
