Low Dose Plerixafor Plus G-CSF in Mobilizing Stem Cells for Autologous Peripheral Blood Transplantation
Study Details
Study Description
Brief Summary
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.

Phase 2 |
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.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Arm 1 Plerixafor 0.12 mg/kg SC will be administered in the evening, 11 hours prior to initiation of apheresis. G-CSF will be administered in the morning at 10 mcg/kg SC for 4 days prior to apheresis. |
Drug: Plerixafor 0.12 mg/kg
Subcutaneously G-CSF 10 mg/kg for 4 days. At day four SC plerixafor 0.12 mg/kg as a single dose 11 hours prior to initiation of aphaeresis.
