Clinical Trials

Are you an adult who does not have high blood pressure and is interested in research? This study will investigate how the brain regulates the body’s response to stress and how infection with HIV or pre-hypertension affects regulation. Your heart and brain activity will be measured while you are at rest, during a mentally stressful task, and while you feel angry. The study will also test whether a breathing exercise improves regulation. People with and without HIV and pre-hypertension will be included. To participate in this study, you must be between 21 and 65 years old and not have high blood pressure. This study is located in Miami, Florida.

Are you an adult who has PAD and difficulty walking? This study is testing whether a medicine that helps the body make more white blood cells can, along with walking exercise, improve symptoms and blood flow in people who have PAD. To participate in this study, you must be between 21 and 80 years old and have PAD. Women must not be pregnant and must use birth control or have been surgically sterilized if they still have menstrual periods. This study is located in Atlanta, Georgia.

Do you or a loved one have pneumonia? This study will test whether combining two medicines to reduce inflammation of the airway and to keep it open may help prevent respiratory failure in people who have pneumonia. To participate in this study, you must be at least 18 years old and have severe pneumonia with low blood oxygen levels.
