What was measured

Relapse rate will be estimated using a percentage of participants who relapsed. It is assumed that the rate of relapse in pediatric acute leukemia post-transplant would be 40%, azacitidine +/- Donor Lymphocyte Infusion (DLI) would reduce the 2-year relapse rate by approximately 40% to a rate of 25%.

Groups in this outcome

Azacitidine/Donor Lymphocyte Infusion

Patients will be stratified according to risk categories (low, standard and high), defined by GVHD status, mixed versus full donor chimerism, and positive versus negative Minimal Residual Disease (MRD) results. Patients will receive up to 7 cycles of low-dose azacitidine (40mg/m2 IV/SC daily x 4 days) at 6 weekly intervals, except for low risk ALL patients who may not receive treatment after withdrawal of immunosuppression. Standard risk patients will receive an additional 6 cycles of azacitidine alone. High risk patients will receive an additional 6 cycles of azacitidine plus escalating DLI. azacitidine: 40mg/m2 IV/SC daily x 4 days, maximum of 7 cycles at 6 weekly intervals donor lymphocyte infusion: For patients with cells available for DLI who are in the high risk group and do not have graft-versus-host disease (GVHD), DLI will be adminstered on day 5 of each cycle.
