Abstract
Purpose: This study evaluates the safety and efficacy of plerixafor (AMD3100), a CXCR4 antagonist, in mobilizing hematopoietic stem cells for autologous stem-cell transplantation in non-Hodgkin's lymphoma (NHL) patients. Patients and Methods: This is a phase III, multicenter, randomized (1:1), double-blind, placebo-controlled study. Patients with non-Hodgkin's lymphoma requiring an autologous hematopoietic stem-cell transplantation in first or second complete or partial remission were eligible. Patients received granulocyte colony-stimulating factor (G-CSF; 10 μg/kg) subcutaneously daily for up to 8 days. Beginning on evening of day 4 and continuing daily for up to 4 days, patients received either plerixafor (240 μg/kg) or placebo subcutaneously. Starting on day 5, patients began daily apheresis for up to 4 days or until ≥ 5 × 106 CD34+ cells/kg were collected. The primary end point was the percentage of patients who collected ≥ 5 × 106 CD34+ cells/kg in 4 or fewer apheresis days. Results: This report presents all data for all patients (n = 298) through 12 months follow-up. Eighty-nine (59%) of 150 patients in the plerixafor group and 29 (20%) of 148 patients in the placebo group met the primary end point (P < .001). One hundred thirty-five patients (90%) in plerixafor group and 82 patients (55%) in placebo group underwent transplantation after initial mobilization. Median time to engraftment was similar in both groups. The most common plerixafor-associated adverse events were GI disorders and injection site reactions. Conclusion: Plerixafor and G-CSF were well tolerated and resulted in a significantly higher proportion of patients with non-Hodgkin's lymphoma achieving the optimal CD34+ cell target for transplantation in fewer apheresis days, compared with G-CSF alone.
