Clinical Trials

Is your family from India, Pakistan, Bangladesh, Nepal, or Sri Lanka? If so, you may be able to participate in a clinical study looking at cardiovascular disease, such as heart disease and stroke among people of South Asian descent. Participants must be between 40 and 84 years old and have no history of heart attack or stroke, heart failure, angina, or atrial fibrillation. This study is taking place in San Francisco, California, Chicago, Illinois, and New York City, New York.

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 a cancer survivor? Would you like to join a clinical trial that is testing whether wearable devices and smartphone apps can help cancer survivors be more active? You must be 18 years old to join. The study is taking place in Worcester, Massachusetts.

Are you a healthy adult who wants to join a study about less sitting? You might qualify for this research. Researchers are testing if walking breaks can improve cardiovascular health, like blood pressure and glucose (sugar) levels. To join, you must be 18 years old and have no long-term health issues or not be taking medications for blood pressure or diabetes. Participants will have to go to the study site for a 9-hour visit and walk on a treadmill during the day. The study is taking place in New York City, New York.

Are you at least 13 weeks pregnant? This study looks at how being less active for most of the day, like sitting a lot and sleeping, affects pregnancy and the mother’s heart health over time. Participants must be 18 to 45 years old and pregnant. They will also wear devices that track their movement and activity. The study is taking place in locations in Iowa, Pennsylvania, and West Virginia.

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.

This study is seeking to determine the safety and tolerability of dronabinol use in adults with SCD compared to placebo.

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.
