  • To determine the PK and explore potential PK drug-drug interactions between plerixafor and MEC. [ Time Frame: Predose, 15 min, 30 min , and 10 hrs ] [ Designated as safety issue: No ]
  • To determine the time to hematologic recovery [ Time Frame: For up to 2 years ] [ Designated as safety issue: No ]
  • To characterize the mobilization of leukemic cells with plerixafor plus G-CSF. [ Time Frame: Baseline, 6 hours ] [ Designated as safety issue: No ]
  • To characterize the effects of plerixafor plus G-CSF on SDF-1/CXCR4 signaling on leukemic blasts. [ Time Frame: Baseline, 6 hours ] [ Designated as safety issue: No ]
  • To determine the time to overall survival [ Time Frame: For up to 2 years ] [ Designated as safety issue: No ]
  • To determine the time to event-free survival [ Time Frame: For up to 2 years ] [ Designated as safety issue: No ]
  • To determine the time to duration of remission [ Time Frame: For up to 2 years ] [ Designated as safety issue: No ]
  • To determine the time to relapse-free survival [ Time Frame: For up to 2 years ] [ Designated as safety issue: No ]

Detailed Description:

In this study, we are seeking to target the leukemia microenvironment to overcome disease resistance. We hypothesize that by disrupting the interaction of leukemic blasts with the bone marrow microenvironment, we may sensitize leukemic blasts to the effects of cytotoxic chemotherapy. In current formulations, the volume of plerixafor required to administer doses higher than 240 mcg/kg may result in significant discomfort with repeated daily injections. In this phase I extension study, we seek to test the safety of both higher doses of plerixafor as well as intravenous dosing to maximize inhibition of the target, CXCR4.
