 Peripheral blood stem cells are obtained by apheresis following a stem cell mobilization regimen. The standard of care regimen for stem cell mobilization includes a growth factor, G-CSF. AMD3100 is given in addition to G-CSF prior to each apheresis session. If enough peripheral blood stem cells for transplant are collected, the patient is treated with high dose chemotherapy in preparation for transplant and is transplanted with cells obtained from the AMD3100 and G-CSF regimen. Patients are followed for safety and transplant outcomes for up to 12 months after transplant.
