Phase 2 trial of intravenously administered plerixafor for stem cell mobilization in patients with multiple myeloma following lenalidomide-based initial therapy.

ABSTRACT: Initial therapy of multiple myeloma with lenalidomide-based regimens can compromise stem cell collection, which can be overcome with the addition of plerixafor. Plerixafor is typically given subcutaneously (SQ), with collection ∼11 h later for maximum yield. Intravenous administration may allow more rapid and predictable mobilization. This trial was designed to assess the efficacy and feasibility of IV plerixafor in patients receiving initial therapy with a lenalidomide-based regimen. Patients received G-CSF at 10 μg/kg/day for 4 days followed by IV plerixafor at 0.24 mg/kg/dose starting on day 5; plerixafor was administered early in the morning with apheresis 4-5 h later. Thirty-eight (97%) patients collected at least 3 × 10(6) CD34+ cells/kg within 2 days of apheresis. The median CD34+ c
