Low Dose Plerixafor Plus G-CSF in Mobilizing Stem Cells for Autologous Peripheral Blood Transplantation

August 9, 2017 updated by: David Gomez Almaguer, Hospital Universitario Dr. Jose E. Gonzalez

Low Dose Plerixafor Plus G-CSF Efficiency in Mobilizing Stem Cells From Lymphoma and Myeloma Patients for Autologous Peripheral Blood Transplantation

Plerixafor, is added to mobilizing chemotherapy and G-CSF to overcome poor stem cell mobilization. We want to demonstrate that half of the commonly prescribed dose can be safely administered once as a single dose in first attempt leading to apheresis yields of >2 x 106 CD34+ cells/kg body weight.

Detailed Description

Plerixafor, is added to mobilizing chemotherapy and G-CSF to overcome poor stem cell mobilization. Consecutive patients in autologous transplant protocol will receive mobilization consisted of daily subcutaneously G-CSF 10 mg/kg for 4 days and plerixafor 0.12 mg/kg as a single dose 11 hours prior to initiation of apheresis. HSC collection was performed with a Cobe Spectra® or Spectra Optia® apheresis system. The planned target blood volume to be processed will be 4-fold total blood volume calculated according to patients' weight and size. Peripheral blood CD34+ counts will be analyzed using flow cytometry. For each ASCT, we aimed for target yields of at least 2 x 106 CD34+cells/kg. Toxicities and engraftment will be documented.
