Clinical Trials

Do you have post-traumatic stress disorder (PTSD) or have experienced a psychosocial trauma, or want to help research? This study uses positron emission tomography/magnetic resonance imaging (PET/MRI) to look at the relationship between psychosocial stress and systemic inflammation/atherosclerosis. This study is located in Boston, Massachusetts, and New York, New York.

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.

his trial will evaluate an oral drug discovered in a high throughput screen, which increases fetal globin protein (HbF and red blood cells expressing HbF)and messenger ribonucleic acid (mRNA) to high levels in anemic nonhuman primates and in transgenic mice.

Sickle Cell Disease (SCD) impairs oxygen transport to tissue and causes endothelial injury. Thus, therapeutic interventions aim to improve both, but there is an unmet need for biomarkers to determine when intervention is necessary and evaluate the effectiveness of the chosen intervention in individual patients. This study proposes to monitor SCD and its treatment through their impact on cerebral hemodynamics, as the brain is one of the most vulnerable and consequential targets of the disease. Specifically, this study will optimize quantitative magnetic resonance imaging (MRI) and advanced optical spectroscopy techniques such as frequency-domain near-infrared and diffuse correlation spectroscopies (FDNIRS-DCS) to monitor 1) cerebral oxygen transport with measures of cerebral blood flow (CBF), cerebral oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen consumption (CMRO2) and 2) endothelial function with cerebrovascular reactivity (CVR).

The main goal of this study is to determine whether the treatment will lead to a complete absence of severe vaso-occlusive events (VOEs) in patients with severe SCD.

Are you 15 to 40 years old and have severe sickle cell disease? This study is comparing long-term outcomes for patients who receive blood and bone marrow transplants and those who receive standard treatment with medicines. Participants also have an option of contributing blood samples to be stored for future research. Participants must be 15 to 40 years old and have severe sickle cell disease. This study is located in Madison, Wisconsin.

Are you an adult with sickle cell disease? This study aims to determine whether monthly exchange blood transfusions (removing blood and replacing it with transfused red blood cells) can improve health and prevent or reduce the number of pain crises. To participate in this study, you must be at least 18 years old, have sickle cell disease, and have not been on a chronic exchange transfusion program for at least 2 months. This study is located in Pittsburgh, Pennsylvania.
