A Combined Study in Pediatric Cancer Patients for Dose Ranging and Efficacy/Safety of Plerixafor Plus Standard Regimens for Mobilization Versus Standard Regimens Alone

2017년 5월 15일 업데이트: Genzyme, a Sanofi Company

A Phase 1/2 Combined Dose Ranging and Randomized, Open-label, Comparative Study of the Efficacy and Safety of Plerixafor in Addition to Standard Regimens for Mobilization of Haematopoietic Stem Cells Into Peripheral Blood, and Subsequent Collection by Apheresis, Versus Standard Mobilization Regimens Alone in Pediatric Patients, Aged 1 to <18 Years, With Solid Tumours Eligible for Autologous Transplants.

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.

  • Ewing's sarcoma, soft tissue sarcoma, lymphoma, neuroblastoma, brain tumors or other malignancy (excluding any form of leukemia) requiring treatment with high dose chemotherapy and autologous transplant as rescue therapy
  • Eligible for autologous transplantation
  • Recovered from all acute significant toxic effects of prior chemotherapy
  • Adequate performance status (for patients ≥16 years of age, defined as Karnofsky score >60 and for patients <16 years of age, defined as Lansky score >60)
