title: Phase III prospective randomized double-blind placebo-controlled trial of plerixafor plus granulocyte colony-stimulating factor compared with placebo plus granulocyte colony-stimulating factor for autologous stem-cell mobilization and transplantation for patients with non-Hodgkin's lymphoma.
abstract: OBJECTIVE
  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.
  
  
  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 microg/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 microg/kg) or placebo subcutaneously. Starting on day 5, patients began daily apheresis for up to 4 days or until > or = 5 x 10(6) CD34+ cells/kg were collected. The primary end point was the percentage of patients who collected > or = 5 x 10(6) 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.
  
  
  CONCLUSIONS
  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.
