Clinical Trials

Do you have pain from sickle cell disease and trouble sleeping? This study will look at whether improving sleep can reduce pain in people who have sickle cell disease and chronic pain. To participate in this study, you must be at least 18 years old, have been diagnosed with sickle cell disease, and experience insomnia and chronic pain. This study is located in Baltimore, Maryland.

Do you have HIV and insomnia? This study is looking at whether insomnia increases pain and inflammation in people who have HIV. To participate in this study, you must be 18 to 85 years old and either be healthy or diagnosed with HIV, with or without insomnia. This study is located in Birmingham, Alabama.

Have you previously been prescribed opioid medicines? This study will find out whether waking up frequently during the night can affect the way your brain processes certain medicines. To participate in this study, you must be 18 to 48 years old, have a normal sleep cycle, and have previously taken opioid medicines to treat pain. This study is located in Baltimore, Maryland.

Are you an adult with sickle cell disease or would like to help research? Some people who have sickle cell disease are at greater risk for developing abnormal blood clots (venous thromboembolism). This could be a blood clot in the leg (called deep vein thrombosis) or a clot that can break off and travel to the lung (called a pulmonary embolism). This study will look at the blood of people who have sickle cell disease and venous thromboembolism, as well as healthy volunteers, to help researchers develop better treatments to prevent blood clots. Participants in this study must be between 18 and 80 years old and be either a healthy volunteer or have sickle cell disease or trait. This study is located in Bethesda, Maryland.

Are you an adult willing to give blood samples? This study investigates ways to prevent blood clotting in people with sickle cell disease. In this population, blood clotting is the most common cause of vascular death after heart attack and stroke. Scientists are studying the blood of people with sickle cell disease and comparing it with the blood of people without sickle cell disease over 2 years. To participate in this study, you must be between the ages of 18 and 80 years old and willing to participate for up to 2 years. This study takes place in Bethesda, Maryland.

This study is testing whether a new imaging technique can help healthcare providers diagnose venous thromboembolism. To participate in this study, you must be at least 18 years old and diagnosed with venous thromboembolism. This study takes place in Boston, Massachusetts.
