Clinical Trials

This study will leverage state-of-the-art, 24-hour behavior assessment in each trimester of pregnancy and examine associations with adverse pregnancy outcomes to inform guidelines and future interventions designed to improve women's pregnancy and long-term cardiovascular health.

The overall goal of the study is to develop a novel weight loss intervention for postpartum people by providing strategies to improve sleep, diet, and physical activity behaviors. In this study, we will recruitment and enroll 40 postpartum people and randomize them to receive the Sleep GOALS intervention or education control to evaluate the intervention's feasibility, acceptability, and preliminary efficacy.

This is a pilot study to evaluate the feasibility and safety of providing RH genotype matched D+ Red Blood Cells (RBCs) to chronically transfused patients with sickle cell disease (SCD) who type D+ but have formed anti-D and are currently transfused with D- RBC (Red Blood Cell) units.

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.

Does your child have overweight or obesity? This study is exploring the link between obesity and sleep deprivation in children. Researchers will test whether participants who do not get enough good quality sleep have trouble making healthy food choices. Participants in this study must be 8 to 12 years old and have overweight or obesity. This study takes place in Pittsburgh, Pennsylvania; and Providence, Rhode Island.

Do you have sickle cell disease and need chronic red blood cell (RBC) transfusions? This study aims to determine the effectiveness of matching donor red cells by RH genotype for people who need frequent RBC transfusions. Participants in this study must be 1 year or older. This study is located in Philadelphia, Pennsylvania.

Are you or your child between the ages of 3 and 21 and experiencing pain episodes? This study tests a treatment called arginine therapy for pain episodes in children with sickle cell disease. Researchers are investigating how safe and effective this treatment is, as well as how arginine is metabolized in the body and its effects on cells. To participate in this study, you or your child must have sickle cell disease and pain that requires medical attention. This study takes place in multiple locations in the United States.
