The Effect of Rituximab on Mobilization With AMD3100 (Plerixafor) Plus G-CSF in Patients With Relapsed or Refractory Non-Hodgkin Lymphoma (NHL) or Hodgkin Disease (HD)

This is a single-center, 2-arm, non-randomized, open-label study to evaluate the safety of plerixafor when used in combination with rituximab (Rituxan®) and granulocyte colony-stimulating factor (G-CSF) in patients with relapsed or refractory Hodgkin disease (HD) or non-Hodgkin lymphoma (NHL). Participants will be assigned to one of 2 arms based on the immunophenotype of their lymphoma. (A)Participants with CD20(-) lymphoma will undergo mobilization with G-CSF and plerixafor. (B) Participants with CD20(+) lymphomas will undergo mobilization with rituximab, G-CSF, and plerixafor. They will receive a weekly dose of 375 mg/m2 rituximab by intravenous (iv) infusion beginning 1 week prior to, and continuing until 2 weeks after, the first dose of G-CSF. Participants in both groups will receive 7.5 µg/kg G-CSF twice daily (morning and evening) for 4 days. In the evening (approximately 10:00 pm) on Day 4, a dose of plerixafor (240 µg/kg) will be administered. Apheresis will be initiated the next morning, approximately 10 to 11 hours after plerixafor is given. Participants will continue to receive G-CSF twice daily and to receive the evening dose of plerixafor followed by apheresis the next morning for up to a total of 4 aphereses or until ≥5\*10\^6 CD34+ cells/kg are collected. Participants with an adequate number of autologous peripheral blood stem cells (PBSCs) collected by apheresis will be admitted to the study center for the administration of high-dose chemotherapy and autologous transplantation. After transplantation, the times to PMN, PLT, and lymphocyte engraftment will be measured. Participants will remain hospitalized until they achieve an absolute granulocyte count of \>500/µl in the peripheral blood. Graft durability will be assessed at 100 days, and 6 and 12 months post-transplantation. This study was previously posted by AnorMED, Inc.
