Abstract

BACKGROUND:

Previous reports suggested that rituximab may impair stem cell collection and posttransplant engraftment in lymphoma patients undergoing autologous hematopoietic progenitor cell transplantation.

STUDY DESIGN AND METHODS:

A prospective biologic allocation study examined the effect of adding rituximab to a mobilization regimen of plerixafor and granulocyte-colony-stimulating factor (G-CSF) for patients with CD20+ lymphoma compared with CD20- lymphoma patients mobilized without rituximab. The primary endpoint was safety of the rituximab-containing regimen; secondary endpoints compared the efficiency of stem cell collection, posttransplant engraftment, graft characteristics, mobilization kinetics, immune reconstitution, and engraftment durability between the cohorts of patients with CD20+ and CD20- lymphoma.

RESULTS:

Fifteen subjects assigned to each treatment arm were accrued. Both mobilization regimens had similar toxicities. The median number of CD34+ cells collected (7.4 × 10(6) /kg vs. 6.4 × 10(6) /kg) and the median numbers of days of apheresis needed to collect stem cells were not different between the CD20+ and CD20- cohorts. No significant differences in neutrophil engraftment (median, 13.5 days vs. 13 days) or platelet engraftment (22 vs. 21 days) or in graft durability were seen comparing patients with CD20+ versus CD20- lymphoma. There were no significant differences in the kinetics of blood T-cell or natural killer-cell reconstitution comparing the two groups. B-cell reconstitution was delayed in the CD20+ lymphoma group, but this did not translate into a significant increase in infectious complications.

CONCLUSION:

Rituximab can be safely added to the combination of plerixafor and G-CSF as a mobilization strategy without excess toxicity or posttransplant engraftment delays for patients with chemosensitive lymphoma undergoing autologous hematopoietic progenitor cell transplantation.
