Description

PRIMARY OBJECTIVES: I. To determine the safety and establish the maximum tolerated dose (MTD) and dose limiting toxicities (DLT) of recombinant interleukin-7 (interleukin 7 [IL-7, CYT107]). SECONDARY OBJECTIVES: I. To determine the rate of cytomegalovirus (CMV), Epstein-Barr virus (EBV) and BK viral...

PRIMARY OBJECTIVES: I. To determine the safety and establish the maximum tolerated dose (MTD) and dose limiting toxicities (DLT) of recombinant interleukin-7 (interleukin 7 [IL-7, CYT107]). SECONDARY OBJECTIVES: I. To determine the rate of cytomegalovirus (CMV), Epstein-Barr virus (EBV) and BK viral infections in cord blood transplant (CBT) patients who receive three doses of 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. IV. To obtain information about the pharmacokinetic (PK) profile of CYT107 by estimating time to maximum concentration (Tmax), concentration maximum (Cmax), half-life, clearance and area-under-the-curve (AUC). 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.
