Study of Plerixafor for Rescue of Poor Mobilizers in Autologous Stem Cell Transplant

"On Day 5 of G-CSF mobilization,~1. if the patient's peripheral CD34+ cell count is \< 7cells/µl then 240ug/kg Plerixafor will be given in the evening prior to receiving 10µg/kg G-CSF and undergoing apheresis the next morning for up to 3 days of apheresis or until ≥ 5x10(6) cells/kg are collected.~2. if the patient's peripheral CD34+ cell count is 7 to 19 cells/ul (inclusive), apheresis will be done. If the apheresis yield is \< 1.3x10(6) CD34+ cells/kg then 240ug/kg Plerixafor will be given in the evening prior to receiving 10 µg/kg G-CSF and undergoing apheresis the next morning. If the apheresis yield is at least double that on Day 5, Plerixafor followed the next morning by G-CSF and apheresis will be repeated for up to a total of 3 days of apheresis or until 5x10(6) cells/kg are collected."
