Official Title
-----------------
A Randomized Multicentre Study Comparing G-CSF Mobilized Peripheral Blood and G-CSF Stimulated Bone Marrow in Patients Undergoing Matched Sibling Transplantation for Hematologic Malignancies

Conditions
-----------------
Transplantation for Hematologic Malignancies

Intervention / Treatment
-----------------
* Procedure: G-PB Transplant
* Procedure: G-BM Transplant


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Recipient must Be between the ages of 16 and 65 years old Have one of the following hematologic malignancies: Acute myeloid leukemia (de novo, secondary or therapy related) in untreated 1st relapse or in remission or with evidence of molecular relapse but blasts less than 5% Chronic myeloid leukemia in chronic or accelerated phase (de novo or therapy related) Myelodysplasia (de novo or therapy related) Other hematologic malignancy (de novo or therapy related) including but not limited to: ALL (CR 1, CR2 or CR3), CLL, non-Hodgkin's lymphoma, Hodgkin's lymphoma Must be receiving a myeloablative conditioning regimen of busulfan and cyclophosphamide or TBI and cyclophosphamide or other myeloablative regimen approved by the Clinical Study Chair. (Regimens containing ATG are not allowed.) Have an HLA-identical sibling donor Meet the transplant centre's criteria for myeloablative allogeneic transplantation* Have an ECOG performance status of 0, 1 or 2 Have given signed informed consent Donor must Be 18 years of age or older. (Upper age limit is at the discretion of the transplant physician at the collection centre.) Be able to undergo general anesthesia and BM harvest or peripheral blood collection as per assessment by a transplant physician. (If an anesthetist assesses a donor after randomization and determines the donor should not undergo general anesthesia, then the donor and recipient will be withdrawn from the study.) Be a sibling of the recipient Be a 6/6 HLA match of the recipient. HLA typing is by serologic or DNA methodology for A and B and by DNA methodology for A and B and by DNA methodology for DRB1 (intermediate resolution) Have given signed informed consent Exclusion Criteria Recipient 1. The recipient is HIV antibody positive Donor The donor is unable to undergo general anesthesia, bone marrow harvest or peripheral blood collection The donor is pregnant or breastfeeding at the time of progenitor cell collection The donor has a history of malignant disease within the last 5 years or current malignancy other than non-melanomatous in situ skin carcinoma or cervical carcinoma in situ The donor is HIV antibody positive The donor has a known sensitivity to E. coli-derived products The donor and recipient are identical twins

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Efficacy | The use of G-BM is associated with a longer time to treatment failure (extensive chronic GVHD, relapse, death) than is the use of G-PB for adult myeloablative allogeneic transplantation for hematologic malignancies. | 2 years |
