Intervention / Treatment
Detailed Description
The primary objective is to determine the proportion of donors whose cells can be successfully mobilized and collected with a sufficient CD34+ cell dose using plerixafor as the mobilizing agent, using an intention-to-treat analysis. Donor mobilization following plerixafor will be considered successful if ≥ 2.0x10e6 CD34+ cells/kg recipient weight are collected in no more than two leukapheresis collections.
All donors receiving plerixafor will be included in the analysis of the primary objective based on the intention-to-treat principle.Recipients will be classified into one of the two strata, myeloablative or reduced intensity, according to his/her conditioning regimen. The target enrollment is 64 donor/recipient pairs, 32 pairs per stratum.
