G-CSF in Stimulating Peripheral Stem Cells for Autologous Stem Cell Transplant in Treating Patients With Chronic Phase Chronic Myeloid Leukemia in Complete Remission

This study has been completed.

National Cancer Institute (NCI) Identifier:
First received: October 5, 2005
Last updated: February 1, 2013
Last verified: January 2008

RATIONALE: Giving colony-stimulating factors, such as G-CSF, helps stem cells move from the bone marrow to the blood so they can be collected and stored until transplant.

PURPOSE: This phase I trial is studying the side effects of G-CSF in stimulating peripheral stem cells for autologous stem cell transplant in treating patients with chronic phase chronic myeloid leukemia in remission.

Condition Intervention Phase
Leukemia Biological: filgrastim Phase 1

Study Type: Interventional
Study Design: Masking: Open Label
Primary Purpose: Treatment
Official Title: Peripheral Blood Stem Cell Mobilization With Filgrastim in Patients With Chronic Myeloid Leukemia in Cytogenetic Response

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Feasibility and safety of harvesting chronic myeloid leukemia (CML) patients in continuous complete remission (CCR) by adequate CD34+ stem cell numbers post-harvest

Secondary Outcome Measures:
  • Effect of discontinuation of imatinib during harvesting by cytogenetic evaluation post-harvest

Estimated Enrollment: 20
Study Start Date: January 2005
Study Completion Date: January 2008
Primary Completion Date: November 2007 (Final data collection date for primary outcome measure)
Detailed Description:


  • Determine the feasibility and safety of harvesting adequate numbers of CD34-positive peripheral blood stem cells using filgrastim (G-CSF) in patients with chronic phase chronic myeloid leukemia in complete cytogenetic remission.
  • Determine the safety of temporarily discontinuing treatment with imatinib mesylate and using G-CSF during the harvesting procedure, in terms of the percentage of Philadelphia chromosome (Ph)-positive cells before and after stem cell harvest, in these patients.

OUTLINE: Patients receive filgrastim (G-CSF) and then undergo apheresis for up to 5 days.

After completion of apheresis, patients resume treatment with imatinib mesylate off study. Patients may later undergo autologous peripheral blood stem cell transplantation, when deemed necessary.

PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study within 2 years.
