A Comparison of Dendritic Cell Content and T-Cell Phenotype Between Granulocyte Colony-Stimulating Factor (G-CSF) or G-CSF + Granulocyte Macrophage (GM)-CSF
This study is currently recruiting participants.
Verified by Emory University, October 2008
Sponsored by: Emory University
Information provided by: Emory University
ClinicalTrials.gov Identifier: NCT00208949
  Purpose

This is a study involving patients who are undergoing allogeneic peripheral blood stem cell transplantation. Both donors and recipients are being sought for this study.


Condition Intervention Phase
Hematologic Diseases
Drug: G-CSF
Drug: GM-CSF
Phase II

Drug Information available for: Sargramostim Granulocyte-macrophage colony-stimulating factor Granulocyte colony-stimulating factor
U.S. FDA Resources
Study Type: Interventional
Study Design: Treatment, Randomized, Open Label, Active Control, Parallel Assignment, Safety/Efficacy Study
Official Title: A Randomized Comparison of Dendritic Cell Content and T-Cell Phenotype Between G-CSF or G-CSF+GM-CSF for the Mobilization of Normal Allogeneic Peripheral Blood Stem Cell Donors

Further study details as provided by Emory University:

Primary Outcome Measures:
  • Determine the effect of G-CSF compared with the combination of G-CSF + GM-CSF on the mobilized peripheral blood stem cell graft [ Time Frame: 30 days + ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Determine if cytokine combination used or the DC content of the stem cell graft will effect the outcomes of GVHD, relapse, time to engraftment, and survival following allogeneic PBSC transplant [ Time Frame: Day 20, 50, 90, 180, 360, 500 ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 20
Study Start Date: September 2002
Estimated Study Completion Date: September 2015
Estimated Primary Completion Date: September 2010 (Final data collection date for primary outcome measure)

Detailed Description:

Patients with leukemia will receive a stem cell transplant, prior to which they will receive medication and/or radiation to destroy all leukemia cells as well as other blood cells. In order to survive this treatment, patients will need to be given the stem cells from another person to replace the blood cells killed by the treatment.

The stem cells given to the recipient will be collected from a relative. To increase the number of stem cells in the relative, he/she is given a growth factor to increase the number of stem cells prior to collection. The standard growth factor used is called G-CSF. In this research study, the physician will give the relative either G-CSF or a combination of G-CSF and GM-CSF, another type of growth factor. Whether the relative receives G-CSF or GM-CSF will be determined by chance. The donors will be randomized to one or the other. It is not known if the stem cells and white blood cells collected using one or both growth factors results in more cures for this disease and fewer side effects, such as graft-versus-host disease.

The reason for doing the study is to determine if the stem cells and other white blood cells collected are any different when different growth factors are given, and to see how well the patient does. The stem cell transplant will in every other way be the same. The only difference is that if the recipient and donor decide to be in this study, the donor will either be given only G-CSF or the combination of G-CSF and GM-CSF and the recipient will receive the stem cells collected.
