Clinical Trials

Hundreds of clinical trials are rolled out around the world monthly, and many of them are designed to specifically uncover and manage the medical needs of people with sickle cell disease and trait. We keep an updated list of these global studies here, so you don’t have to go searching for them. There might be active study recruitment and enrollment happening at a site near you. Explore the list below to see the different types of studies, and use the navigation options on the left to get as specific as you would like.

Sickle Cell Disease and CardiovAscular Risk – Red Cell Exchange Trial (SCD-CARRE)

The SCD-CARRE trial is a Phase 3, prospective, randomized, multicenter, controlled, parallel two-arm study aimed to determine if automated exchange blood transfusion and standard of care administered to high mortality risk adult SCD patients reduces the total number of episodes of clinical worsening of SCD requiring acute health care encounters (non-elective infusion center/ER/hospital visits) or resulting in death over 12 months as compared with standard of care.

Clinical Transplant-Related Long-term Outcomes of Alternative Donor Allogeneic Transplantation (BMT CTN 1702)

The purpose of this study is to determine if a search strategy of searching for an HLA-matched unrelated donor for allogeneic transplantation if possible then an alternative donor if an HLA-matched unrelated donor is not available versus proceeding directly to an alternative donor transplant will result in better survival for allogeneic transplant recipients within 2 years after study enrollment.
