About the study

The main objective of this study is to prove the superiority of a procedure which calculates
the volume of RBCs to transfuse and the time between apheresis based on this algorithm,
compared to the current procedure. The primary endpoint would be the number of patients with
individually achieved objectives in terms of % HbS before each apheresis (which reflects the
effectiveness of the previous apheresis) over a period of 12 months. The secondary objectives
would be to compare the volume differences of transfused RBCs in both groups over a period of
12 months, the occurrence of clinical events and the satisfaction of patients and physicians.

The investigators hope that this study would improve the efficiency and the performance of
apheresis in sickle cell patients. The investigators also hope to facilitate the organization
of procedures with the flexibility that would allow the use of this algorithm.
