Etoposide, Filgrastim, and Plerixafor in Improving Stem Cell Mobilization in Treating Patients With Non-Hodgkin Lymphoma

PRIMARY OBJECTIVES:

I. To determine whether the addition of plerixafor improves the proportion of patients with lymphoma who collect >= 8 x 10^6 cluster of differentiation (CD)34+ cells/kg within two days by 25% compared to the historical estimate of 42% with etoposide and G-CSF (filgrastim).

II. To determine whether patients achieving collection of >= 8 x 10^6 CD34+ cells/kg have a 15% one year survival advantage relative to the historical estimate of 68% among patients mobilizing >= 2 but < 8 x 10^6 CD34+ cells/kg with etoposide and G-CSF.

SECONDARY OBJECTIVES:

I. To demonstrate that patients receiving >= 8 x 10^6 CD34+ cells/kg have more rapid neutrophil and platelet recovery and earlier hospital discharge than those receiving < 8 x 10^6 CD 34+ cells/kg.

II. To compare overall survival and progression-free survival between patients receiving >= 8 x 10^6 CD34+ cells/kg and those receiving < 8 x 10^6 CD34+ cells/kg.

III. To compare number of days of apheresis required to achieve goal, transfusion requirements, hospitalization costs, need for remobilization between groups.

IV. To evaluate whether peripheral CD34+ cell count correlates with graft content of CD34+ cells.

OUTLINE:

Patients receive etoposide intravenously (IV) over 4 hours on day 0, filgrastim subcutaneously (SC) once daily (QD) beginning day 1, and plerixafor SC 15-18 hours prior to apheresis. Patients unable to achieve target collection of >= 8 x 10^6 CD34+ cells/kg receive another dose of plerixafor followed by apheresis. Following the second apheresis, patients achieving =< 2 x 10^6 CD34+ cells/kg may continue filgrastim with plerixafor and continue collection according to the attending physician.

After completion of study treatment, patients are followed up at 28 days and then for at least 1 year.
