Donor Enhancement With Plerixafor Post Myeloablative Allogeneic Transplant

March 24, 2017 updated by: Mitchell Horwitz, MD

A Phase I/II Study: Enhancing Donor Hematopoietic Cell Engraftment With Plerixafor in Myeloablative Allogeneic Hematopoietic Cell Transplantation

This phase I/II clinical trial will test the safety and the efficacy of post transplant administration of plerixafor in enhancing hematological recovery in humans. Patients who are appropriate candidates for myeloablative allogeneic stem cell transplantation from an HLA-matched sibling, matched unrelated donor or umbilical cord blood are eligible for enrollment. The investigators plan to enroll a total of 50 patients for this study (30 patients with HLA-matched sibling or matched unrelated donor transplant, and 20 patients with umbilical cord blood transplant). During phase I study, a small number of patients (3-6 patients from each group) will be enrolled to determine the safety of post transplant administration of plerixafor. Patients will receive plerixafor given at 240 µg/kg subcutaneously every other day beginning at day +2 after transplant until day +21 or engraftment. Limiting toxicities are defined as primary or secondary graft failure, plerixafor-related severe premature ventricular arrhythmia or death. If safety criteria are met from the investigators phase I study, the investigators will proceed with phase II study to determine the efficacy of post transplant administration of plerixafor in enhancing haematological recovery. The experimental aspect of this study is the use of plerixafor and all other aspects of care will be in line with the standard of care. Both Phase I and Phase II patients will be combined for efficacy analysis, and data collected from this study will be compared with the investigators historical control. The results from this study will set the stage and provide the justification for a larger phase 3 trial.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Recruitment to this trial will be stratified by donor type as HLA (human leukocyte antigen) matched sibling, matched unrelated donor or umbilical cord blood. Patients will be conditioned with a myeloablative regimen such as, but not limited to, total body irradiation and cyclophosphamide. The donor stem cell grafts will come from mobilized peripheral blood of 8/8 or 7/8 HLA-identical family members, 8/8 (HLA A, B, C, DRBeta1) allele-level matched unrelated donors, or dual umbilical cord blood grafts with at least 4 of 6 HLA matching at HLA A and B (low resolution) and DRBeta1 (at high resolution). The target CD34+ cell dose will be 5 X 10(6)/kg recipient ideal body weight. For HLA matched sibling or matched unrelated donor (MUD) transplants, all patients will receive a minimum of 2 X 10(6) CD 24+ cells/kg. For cord blood transplants, each unit will contain a minimum total nucleated cell count of of 1.5 X 10(7)/kg. Post-transplant GVHD (graft versus host disease) prophylaxis will be given per institutional standard.
