Last verified: February 2013

RATIONALE: There are different methods of stem cell mobilization, such as using colony-stimulating factors alone or following chemotherapy priming. More recently, the combination of plerixafor and colony-stimulating factors has been shown to enhance stem cell mobilization. This study will assess whether the combination of plerixafor and Granulocyte Colony-Stimulating Factor (G-CSF) is effective following chemotherapy mobilization with cyclophosphamide.

PURPOSE: To assess the safety, tolerability, and best dose of intravenous plerixafor following cyclophosphamide priming.

Primary Outcome Measures:
  • To assess the MTD ( maximum tolerated dose) of IV plerixafor when given post cyclophosphamide and GCSF for stem cell priming.Dose limiting toxicity will be defined as any grade 3 or 4 nonhematologic toxicity. [ Time Frame: 12 to 18 months ]
  • Tolerability and safety of PLERIXAFOR [ Time Frame: 6 months post transplant ]
    Will be summarized in terms of type, severity (by National Cancer Institute Common Terminology Criteria for Adverse Events [NCI CTCAE] v4.0), date of onset, duration, reversibility, and attribution.

Secondary Outcome Measures:
  • Frequency of collecting 5 x 10^6 or more CD34+ cells/kg in 2 or less apheresis days [ Time Frame: 5 days post apheresis completion ]
  • Percentage of plasma cells [ Time Frame: 5 days post apheresis ]
  • Completion of 100 days post-transplant [ Time Frame: 100 days post-transplant ]
  • Overall and disease-free survival [ Time Frame: 6months and one year post transplant ]
  • Time to engraftment [ Time Frame: 6 months post transplant ]

Enrollment: 18
Study Start Date: April 2010
Study Completion Date: February 2013
Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm I

MOBILIZATION: Patients receive cyclophosphamide IV. Patients also receive filgrastim subcutaneously (SC) daily beginning approximately 24 hours later.

TREATMENT/APHERESIS: Beginning 10 days after cyclophosphamide, patients receive plerixafor IV over 30 minutes followed by filgrastim SC on each day of apheresis.

Detailed Description:


I. To assess the safety and tolerability of intravenous(IV) PLERIXAFOR when given in combination with cyclophosphamide and G-CSF as a mobilization regimen in patients with Multiple Myeloma.


I. To determine if intravenous PLERIXAFOR, given with a cyclophosphamide and G-CSF mobilizing regimen, will allow collection of greater than or equal to 5 x 10^6 CD34+ cells/kg in 2 or less apheresis days.

II. To review the timing of intravenous plerixafor administration prior to apheresis and describe our experience.


MOBILIZATION: Patients receive cyclophosphamide intravenously (IV). Patients also receive filgrastim subcutaneously (SC) daily beginning approximately 24 hours later.

TREATMENT/APHERESIS: Beginning 10 days after cyclophosphamide, patients receive plerixafor IV over 30 minutes followed by filgrastim SC on each day of apheresis.

Following the collection of an adequate number of stem cells, patients undergo high-dose chemotherapy and autologous stem cell rescue. Patients are followed post-autologous stem cell transplant for engraftment.

After completion of study treatment, patients are followed periodically.
