Clinical Trials

This research will investigate whether the stress response physiology and autonomic function in response to mental stress are different in women with CMD compared to other groups.

Are you a current patient at Massachusetts General Hospital or Brigham and Women’s Hospital with clinical depression and heart failure or unstable chest pain (called angina)? This study is investigating whether 26 weeks of education and increased monitoring from healthcare managers improves psychiatric and heart symptoms better than self-managed care. This study takes place in Boston, Massachusetts.

Do you have stable angina and myocardial bridging but not obstructive coronary artery disease (CAD)? This study aims to help improve treatments for people that have angina in the absence of obstructive CAD. Angina without CAD affects millions of people but remains underdiagnosed and treatments are lacking. To participate in this study, you must be between 18 and 80 years old. This study takes place in Stanford, California.

Do you or your child have a platelet, bleeding, or white blood cell disorder? This study is looking at people who have platelet or other blood disorders. The researchers will use a blood sample to look for problems with platelets and a possible genetic cause in the participant’s DNA or RNA. To participate in this study, you must be a child or adult who either is healthy or has a platelet disorder, coagulation disorder, or white blood cell disorder. This study is located in New York, New York.

Does your infant have a low platelet count? This study is investigating the safety and efficacy of platelet transfusion as a treatment for infants with thrombocytopenia. Researchers are looking at the positive effects of platelet transfusion against the negative effects, such as the release of inflammatory molecules and the formation of blood clots. To participate in this study, your child must be younger than 6 months old and have a low platelet count (less than 100 × 109/L). This study takes place in Boston, Massachusetts.

Does your infant have a low platelet count? This study investigates immature platelet counts as a marker for bleeding risk in newborns with thrombocytopenia, compared with platelet counts alone. Immature platelets are the most recently produced platelets and may be a better marker of platelet production. To participate in this study, you must have a newborn who is less than 32 weeks’ gestational age, has a birth weight greater than 500 grams, and has a platelet count less than 100 × 109/L. This study takes place in multiple locations in the United States, the Netherlands, and Sweden.

Are you an adult with polycythemia vera or thrombocytosis? This study aims to find a new treatment or cure for polycythemia vera and thrombocytosis by locating genes and their changes, or mutations, that may contribute to these disorders. To participate in this study, you must have polycythemia vera with elevated hemoglobin (higher than 18 in men and 16 in women) or thrombocytosis with an elevated platelet count (higher than 450,000). This study takes place in Salt Lake City, Utah.

The purpose of this project is to test sleep reactivity as an independent cause of Shift Work Disorder (SWD). The primary hypothesis is that those with high sleep reactivity will show persistent SWD symptoms after experimental reduction of circadian misalignment, which will then be mitigated with CBT.

This study is designed to assess how healthy premenopausal women respond to different patterns of sleep loss at different times in the menstrual cycle.

This study will conduct a randomized controlled trial evaluating a melatonin intervention started during hospitalization and continued after discharge compared to placebo. The trial will investigate if this intervention is feasible, acceptable, and effective at reducing sleep wake disturbances as measured on the Sleep Disturbances Scale for Children 1-month after hospital discharge.
