Abstract
BACKGROUND This Phase 3 randomized, double-blind study evaluated the efficacy and safety of plerixafor plus granulocyte-colony-stimulating factor for the mobilization of hematopoietic stem cells in Chinese patients with non-Hodgkin's lymphoma. STUDY DESIGN AND METHODS Adults (ages 18-75 years) with non-Hodgkin's lymphoma in first or second complete or partial remission, without previous hematopoietic stem cell mobilization or autologous transplant, were included. Patients received granulocyte-colony-stimulating factor 10 micro g/kg/day from Days 1 through 4 before they were randomized (1:1) to receive either plerixafor 0.24 mg/kg/day or placebo subcutaneously on Days 4 through 7 plus continued granulocyte-colony-stimulating factor on Days 5 through 8. Apheresis began on Day 5 and continued for no more than 4 days. The primary endpoint was collection of 5 x 106 CD34+ cells/kg or greater over no more than 4 days of apheresis. Other endpoints included the collection of 2 x 106 CD34+ cells/kg or greater and safety. RESULTS Overall, 101 patients were enrolled, and 50 were randomized to each group. More patients in the plerixafor group achieved 5 x 106 CD34+ cells/kg or greater (62 vs. 20%; p<0.0001) or 2 x 106 CD34+ cells/kg or greater (88 vs. 66%) and underwent transplantation (88 vs. 68%) compared with those in the placebo group. The most common plerixafor-related adverse events were nausea (7.8%) and diarrhea (3.9%). CONCLUSION Plerixafor plus granulocyte-colony-stimulating factor is superior to placebo plus granulocyte-colony-stimulating factor for the mobilization of CD34+ cells for autologous transplantation and is generally well tolerated in Chinese patients with non-Hodgkin's lymphoma.
