Promising trial results reducing risk of GVHD and progression.
“The primary endpoint was day 200 hematopoietic cell transplant failure, with the objective of reducing the incidence to <20%. Primary endpoint was reached on Arm A at dose Level-1 (300 cGy total body irradiation) with a cumulative incidence of day 200 hematopoietic cell transplant failure of 11%, and on Arm B at dose Level-3 (450 cGy) with a cumulative incidence of day 200 hematopoietic cell transplant failure of 9%. Increasing the total body irradiation dose leads to a higher success rate with nonmyeloablative conditioning by reducing relapse and rejection.”
