Protocol - Sickle Cell Disease Transplant Conditioning Regimen

Add to My Toolkit

This protocol uses existing medical records to document the types of conditioning agents, duration of exposure to conditioning agents, and timing of exposure to conditioning agents administered to a patient prior to stem cell transplantation for sickle cell disease.

Specific Instructions

The Sickle Cell Disease Curative Therapy Working Group notes that investigators may need to add more lines to the protocol to capture all agents used. Additionally, area under the curve (AUC) will be applicable only for certain chemotherapy agents.

Selection Rationale

The Cure Sickle Cell Initiative (CureSCi) Transplant Conditioning Regimen Case Report Form was designed for use in sickle cell disease. It was also chosen because it describes specific conditioning agents, dosages, and timing rather than using general terminology for conditioning regimens, such as “myeloablative” or “non-myeloablative.”

This measure describes the combination of treatments, or conditioning regimen, used to prepare a patient with sickle cell disease for stem cell transplantation, including chemotherapy, monoclonal antibody therapy, other serotherapy, and whole-body radiation therapy.


The purpose of a conditioning regimen is to make room in the patient’s bone marrow for new (or donor) blood stem cells to grow, prevent the patient’s body from rejecting the transplanted cells, and increase the chances of a successful transplant. A conditioning regimen used for stem cell transplant plays a significant role in the outcome of the transplant, including potential for success; risk of graft versus host disease; potential for graft failure; and complications including infection, infertility, changes in organ function, and secondary complications such as malignancy.
