Evaluation of Pegfilgrastim for Stem Cell Mobilization in Children

Phase 2
Terminated
Conditions
Solid Malignancies
Registration Number
NCT00695370
Lead Sponsor
University Hospital, Clermont-Ferrand
Brief Summary

Hypothesis: pegfilgrastim at 300 µg/kg in hematological steady state provides an efficient stem cell mobilization in children with malignancies

Design: phase 2 study.

Judgment criterion: percentage of children achieving at least 5x10e6 CD34 cells with a standard apheresis (less than 2 blood volume processed)

Detailed Description

Patients: consecutively referred for HSC mobilization. At least 17 days after the previous chemotherapy. No hematological growth factor during the 8 previous days.

Mobilization: one sc injection of 300 µg/kg pegfilgrastim (Neulasta, Amgen)

Evaluation during the study: CD34 circulating cells from day 2 to day 7 ; AE recording

Judgment criterion: percentage of children achieving at least 5x10e6 CD34 cells with a standard apheresis (less than 2 blood volume processed)

Analysis: sequential Bayesian study
