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

15 mai 2017 mis à jour par: 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.

  • Age 2 to < 18 years during stage 1 and 1 to < 18 years during stage 2

  • 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)
  • Absolute neutrophil count >0.75 × 10^9/L
  • Platelet count >50 × 10^9/L

  • Persistent high percentage marrow involvement prior to mobilization will be prohibited.
  • On-going toxicities (excluding alopecia) Grade ≥2 resulting from prior chemotherapy
  • Acute infection

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
