NCT01818284

Brief Summary

The goal of this clinical research study is to learn if treating stem cell donors with filgrastim (G-CSF) and plerixafor (Mozobil®) can cause them to produce a higher number of blood stem cells than filgrastim by itself. Researchers also want to learn if giving both of these drugs helps donors produce enough stem cells so that only 1 apheresis procedure needs to be performed. Researchers will study if using both drugs lowers the risk of the stem cell transplant recipients developing severe forms graft-versus-host disease (GVHD). GVHD is a condition in which transplanted tissue (such as blood stem cells) attacks the tissue of the recipient's body. The safety and effectiveness of this drug combination will also be studied. Filgrastim and plerixafor are both designed to help move or "mobilize" the stem cells from the bone marrow to the blood.

Outcome Measures

Primary Outcomes (2)

  • Summary of Most Common Toxicity: Donor Safety in Mobilizing Peripheral Blood Progenitor Cells (PBPC)

    Primary safety endpoint is the development of any unexpected toxicity (any grade 2 or higher non-hematologic toxicity) in donors. The severity of the toxicity - adverse events (AEs) graded according to Common Terminology Criteria v4.0 (CTCAE).

    5 days

  • Feasibility in Mobilizing PBPC in Donors: Number of Donors Reaching Stem Cell Target Collection on First Day of Collection Following Treatment of Filgrastim Plus Plerixafor

    Study determined to be feasible if all donors were able to receive Plerixafor without developing any grade 2 or higher non-hematologic toxicity. Feasibility of the combination of Filgrastim, Granulocyte-colony stimulating factor (G-CSF) plus Plerixafor is to effectively mobilize CD34+ cells so that an adequate transplant (\>4 x 10\^6 CD34+ cells/kg) can be reliably collected with one apheresis for allogeneic HSCT.

    4 days

Study Arms (1)

Filgrastim + Plerixafor

EXPERIMENTAL

Each donor receives Filgrastim 5 µg/kg subcutaneously in the morning daily for 4 days. The dose of Filgrastim based on the donor's actual body weight. Donors will continue Filgrastim until completion of apheresis. Each donor receives Plerixafor 240 µg/kg subcutaneously in the evening on the fourth day of Filgrastim mobilization. The dose-volume of Plerixafor based on the donor's actual body weight. Apheresis procedure to start the morning of day 5, approximately 10 to 11 hours after the administration of Plerixafor. The apheresis procedure will start in the morning of day 5, approximately 10 to 11 hours after the administration of Plerixafor. The apheresis procedure may continue beyond day 1 until the target dose of 4x106 cluster of differentiation 34 (CD34+) cells/kg (recipient's weight) is obtained.
