2018-0674 - IL-7 for T-Cell Recovery Post Haplo and CB Transplant - Phase I/II

PRIMARY OBJECTIVES: I. To determine the safety and establish the optimal biologic dose of glycosylated recombinant human interleukin-7 (CYT107). SECONDARY OBJECTIVES: I. To determine the rate of cytomegalovirus (CMV), Epstein-Barr virus (EBV) and BK viral infections in umbilical cord blood stem cell transplantation (CBT) and haploidentical stem cell transplantation (haplo-SCT) patients who receive three doses of interleukin-7 (IL-7) following engraftment. II. To calculate the overall survival (OS), progression-free survival (PFS), and cumulative incidence of graft versus host disease (GVHD) and cumulative incidence of relapse. III. To evaluate the effects of CYT107 on the recovery of T, natural killer (NK) and B cell populations and their functions in vitro; these data will be used to identify the optimal dose to move to a phase II trial. OUTLINE: This is a dose-escalation study. Within 60-180 days after CBT, patients receive recombinant interleukin-7 intramuscularly (IM) or subcutaneously (SC) once per week for 3 weeks. After completion of study treatment, patients are followed for up to 3 years.
