G-CSF in Stimulating Peripheral Stem Cells for Autologous Stem Cell Transplant in Treating Patients With Chronic Phase Chronic Myeloid Leukemia in Complete Remission
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.
|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|
- Feasibility and safety of harvesting chronic myeloid leukemia (CML) patients in continuous complete remission (CCR) by adequate CD34+ stem cell numbers post-harvest [ Designated as safety issue: Yes ]
- Effect of discontinuation of imatinib during harvesting by cytogenetic evaluation post-harvest [ Designated as safety issue: No ]
|Study Start Date:||January 2005|
|Study Completion Date:||January 2008|
|Primary Completion Date:||November 2007 (Final data collection date for primary outcome measure)|
- 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.
