  Purpose

This is a multi-site study with plerixafor in pediatric cancer patients. The study will be conducted in 2 stages:

  • Stage 1 is a dose-escalation study.
  • Stage 2 is an open-label, randomized, comparative study using the appropriate dosing regimen identified in the Stage 1 dose-escalation study.

All participating patients will receive a standard mobilization regimen as per study site practice guidelines (either chemotherapy plus once daily granulocyte-colony stimulating factor (G-CSF) or once daily G-CSF alone). The only change to the standard mobilization regimen is the addition of plerixafor treatment prior to apheresis for all patients in Stage 1 (dose escalation), and for those patients randomized to the plerixafor plus standard mobilization treatment arm in Stage 2 (randomized, comparative).

Stage 1 will enroll at least 27 patients. Stage 2 will enroll at least 40 patients.

If patients are on investigational drugs as part of their anti-cancer regimen, this should be discussed with the Sponsor before screening. Drugs approved for other indications that are being used in a manner considered standard of care for this transplant procedure are allowed
  • The patient (and/or their parent/legal guardian), in the opinion of the Investigator, is unable to adhere to the requirements of the study
