This study evaluates the safety and efficacy of plerixafor given in addition to granulocyte-colony stimulating factor (G-CSF) for collection of peripheral blood stem cells (PBSCs) for autologous transplantation in patients with non-Hodgkin's lymphoma (NHL) and multiple myeloma (MM). Efficacy outcomes include evaluation of fold increase in circulating CD34+ cells from just before the first plerixafor injection to 10-11 hours post plerixafor (just before apheresis) and assessment of successful polymorphonuclear leukocyte (PMN) engraftment after transplantation. Data from this protocol will assist in the determination of the dosing schedule for future studies.
Participants with NHL and MM who have undergone prior cyto-reductive chemotherapy, are to be autologously transplanted, and meet the inclusion/exclusion criteria are eligible to enter the study. The only change to the standard of care is the addition of plerixafor to a granulocyte colony-stimulating factor (G-CSF) mobilization regimen on the day prior to apheresis. Participants will undergo mobilization with G-CSF (10 mcg/kg each day) and will receive plerixafor (240 mcg/kg) in the evening prior to apheresis. Participants will undergo apheresis for up to 5 consecutive days in order to collect the target number of CD34+ stem cells (≥ 5\*10\^6 CD34+ cells/kg for either single or tandem transplant). After apheresis, all participants will be treated with high-dose chemotherapy in preparation for transplantation. Participants will be transplanted with cells obtained from the G-CSF and plerixafor mobilization regimen. The increase in CD34+ cells in the peripheral blood from the time of the plerixafor dose to just prior to apheresis and the number of CD34+ cells in the apheresis product will be measured. The number of apheresis sessions required to obtain ≥ 5\*10\^6 CD34+ cells will also be measured. Success of the transplantation(s) will be evaluated by the time to engraftment of polymorphonuclear leukocytes (PMN) and platelets (PLT). Participants will be followed for durability of their transplant for 12 months following transplantation. This study was previously posted by AnorMED, Inc.

Participants underwent mobilization with G-CSF 10 µg/kg/day for 4 days, administered by subcutaneous injection (SC) injection each morning. On the evening of Day 4, participants received a dose of plerixafor 240 µg/kg, administered by SC injection. On Day 5, participants returned to the clinic and received a morning dose of G-CSF 10 µg/kg and underwent apheresis approximately 10 to 11 hours after the dose of plerixafor (within 60 minutes after administration of G-CSF). Participants continued to receive an evening dose of plerixafor followed the next day by a morning dose of G-CSF and apheresis for up to a maximum of 5 aphereses or until ≥ 5\*10\^6 CD34+ cells/kg were collected.

Number of Participants in Overall Safety Summary of Treatment Emergent Adverse Events (TEAE)
Number of participants with treatment emergent adverse events (TEAEs) collected from Day 1 (start of G-CSF mobilization) to the day before starting chemotherapy (approximately day 38). AEs were graded by the investigator using the World Health Organization (WHO) Adverse Event Grading Scale and were assessed for severity (mild, moderate, severe) and relatedness to study treatment (5 point scale from 'not related' to 'definitely related').
Time frame: Day 1 to approximately Day 38 (before start of chemotherapy)
Number of Participants Achieving a Two-Fold (Relative) Increase in Peripheral Blood (PB) CD34+ Cells/µL Following the First Dose of Plerixafor
The number of participants mobilized with G-CSF + plerixafor injection who have a ≥ 2-fold increase in CD34+ cells. Fold increase was expressed as a ratio. Fold increase = (pre-apheresis PB CD34+ cells/µL) / (pre-plerixafor dosing PB CD34+ cells/µL)
Time frame: Days 4-5 (first dose of plerixafor to apheresis)
Number of Transplants in Which Participants Achieved Polymorphonuclear Leukocyte (PMN) Engraftment by Day 12 But No Later Than Day 21 Post Peripheral Blood Stem Cell (PBSC) Transplant
Participants were monitored for polymorphonuclear leukocyte (PMN) engraftment as per the local standard of care. The target for engraftment was 12 days after PBSC transplant and no transplant taking longer than 21 days for engraftment.
Time frame: 2 months
