次要终点：Incidence of Grade II-IV acute GvHD (aGvHD).；Incidence of Grade III-IV acute GvHD (aGvHD).；Incidence and severity of chronic GvHD (cGvHD)；Overall survival at Day +365.

• TRX-103 · EXPERIMENTAL · TRX-103 will be infused on time post hematopoietic stem cell transplant (HSCT).

The purpose of this Phase 1, first in human open-label study is to assess the safety and tolerability of TRX-103 in patients with hematological malignancies undergoing HLA-mismatched related or unrelated hematopoietic stem cell transplantation (HSCT). It is anticipated that up to 36 Subjects will be enrolled during a 18-24 month enrollment period. TRX-103 will be infused one time post HSCT.
