Research Protocols Being Reviewed Under 45 CFR 46.407

A Phase III Randomized Trial of G-CSF Stimulated Bone Marrow vs. Conventional Bone Marrow as a Stem Cell Source In Matched Sibling Donor Transplantation


Requesting IRB:

Nemours Oncology IRB, Nemours Foundation, Jacksonville, Florida

Study Summary:

This research protocol is a Phase III trial that proposes to compare two graft sources for children undergoing bone marrow transplantation for leukemia. The bone marrow will be harvested from healthy matched sibling donors. Sibling donors in the experimental group will receive filgrastim (G-CSF) for five days before the harvesting procedure; sibling donors in the control group will only undergo a standard bone marrow harvest.

The study uses a prospective, randomized design for 415 donor-subjects and 415 patient-subjects, with patient-subject assessments at 1, 6, and 12 months (with possible yearly monitoring for 10 years).

The major hypothesis is that the filgrastim-stimulated bone marrow will improve event-free survival. The major study endpoints are treatment-related mortality at 100 days, rates of graft failure, and rates of graft versus host disease.

The protocol includes two optional companion studies:

  • "RD Safe" to evaluate short- and long-term risks to donors
  • A biology study to assess cellular immune response and store the subjects' blood for future unspecific research
