Brief summary

The purpose of this study is to find out if getting a blood stem cell transplant with donor stem cells given over several days is better than getting a blood stem cell transplant with donor stem cells given over 1 day. We want to find out which procedure over will result in improved recovery of blood and immune function after transplant. When donor stem cells are given over various days in mice, the blood and immune system recovery is quicker.

Detailed description

This is a complex study that involves various interventions, Intervention #1: Donor Initial Stem Cell Collection; Intervention #2: Stem Cell Product Initial Processing Orders; Intervention #3 Patient Admission and Transplantation; Intervention #4: Stem cell infusion; Intervention #5: Post infusion follow up; Intervention #6: Off Study Patient and Donor Evaluation. Patients whose donor fails to collect the appropriate number of cells will receive all their cells as a bulk infusion. These patients will continue to receive a transplant on protocol but will be replaced until both arms have reached the target accrual.

Pre-assignment details

The study goal was to explore fractionated HPC infusion in humans in a setting of commonly used conditioning regimens. The design included stratification of randomization by transplant type. Additional stratification would have increased the accrual target for statistical power, prolonging enrollment. In our publication reporting results of this trial (Tamari et al. JTCT 2021) we provide data stratified by treatment arm and transplant type for secondary endpoints for easier interpretation.
