Purpose
This protocol will investigate the effectiveness of plerixafor in the up-front setting in avoiding a second round of mobilization and whether this translates into a clinical and economic benefit.

| Official Title: | Clinical And Economic Impact Of Upfront Plerixafor In Autologous Transplantation |
- Rate of successful collection with early introduction of plerixafor in patients predicted to be poor mobilizers [ Time Frame: Day 2 of apheresis ] [ Designated as safety issue: No ]The primary endpoint of the study will be the rate of successful collection with early introduction of plerixafor in patients predicted to be poor mobilizers based on peripheral blood CD34+ cell counts or CD34+ cell collection efficiency after 2 consecutive days of apheresis. Success will be defined as the ability to avoid a second mobilization attempt. Results will be compared to matched historical controls.
- Economic impact [ Time Frame: Day 2 of mobilization and Day +100 after transplantation ] [ Designated as safety issue: No ]The economic impact of plerixafor use will be divided into two phases, mobilization and transplantation. The comparator arm for the mobilization phase would be matched historical controls. The comparator arm for the transplant phase will be patients who did not require plerixafor for mobilization during the study period.
- Kinetics of CD34+ mobilization with early introduction of plerixafor [ Time Frame: On Day 1 and Day 2 of apheresis ] [ Designated as safety issue: No ]
The kinetics of CD34+ cell counts during mobilization in this setting is unknown. We will attempt to determine mobilization kinetics by following peripheral blood CD34+ counts daily starting from first day of plerixafor administration until completion of apheresis. Kinetics will be analyzed according to the following parameters:
- Peripheral CD34 cell counts on each day of apheresis.
- Total CD34 cells collected on each day of apheresis
- Multiple myeloma vs. NHL.
- Graft composition [ Time Frame: On Day 1 and Day 2 of apheresis ] [ Designated as safety issue: No ]Graft composition will be analyzed on each day of successful apheresis. Cell populations to be quantitated include total CD3+ lymphocytes, CD4+ lymphocytes, CD8+ lymphocytes.

Experimental: Plerixafor
All subjects will receive filgrastim as part of their primary mobilization regimen. If a subject does not meet minimum peripheral blood CD34+ cell count levels or fails to adequately collect a threshold number of CD34+ cells, plerixafor will be added to the mobilization regimen.

Drug: Plerixafor
240 mcg/kg/day based on ideal body weight will be given for the following conditions:
Other Name: AMD3100
Drug: Filgrastim
All patients will receive filgrastim starting 4 days prior to apheresis (D1-4 mobilization). The dose and schedule of filgrastim will based upon the risk category of the patient:
Other Name: G-CSF

Active Comparator: Observation
All subjects will receive filgrastim as part of their primary mobilization regimen. If the subject meets minimum peripheral blood CD34+ cell count levels or adequately collects a threshold number of CD34+ cells, plerixafor will not be added to the mobilization regimen.

Drug: Filgrastim
All patients will receive filgrastim starting 4 days prior to apheresis (D1-4 mobilization). The dose and schedule of filgrastim will based upon the risk category of the patient:

Detailed Description:
Peripheral blood stem cells are now considered the standard source of stem cells for autologous stem cell transplants. Unfortunately, there is still a 20-30% chance that inadequate numbers of stem cells will be collected, resulting in prolonged recovery of cell counts after transplantation and increased transfusion dependence. There is also a significant economic burden associated with remobilization and a risk that delays in collecting sufficient numbers of stem cells can result in an increased chance of disease recurrence prior to transplantation.
