I. To assess the tolerability and safety of escalating doses of T-allo10 cell infusions that can be feasibly manufactured to meet release specifications in mismatched related or mismatched unrelated unmanipulated hematopoietic stem cell transplantation (HSCT) in patients with hematologic malignancies.
I. To assess the incidence of grade III and IV acute graft versus host disease (GvHD).
I. To assess the incidence and severity of chronic GvHD.
II. To assess the time to immune reconstitution.
III. To assess disease free survival.
OUTLINE: This is a dose-escalation study of T-allo10 cells.
Patients undergo fractionated total body irradiation (FTBI) on days -8 to -5. Patients receive cyclophosphamide intravenously (IV) on days -4 and -3. Patients receive T-allo10 cells IV within 30 minutes of thawing of cells on day -1 and undergo HSCT on day 0.
After completion of study treatment, patients are followed up on days 21, 28, 35, 42, 49, 56 and monthly until day 365.
