Summary

This is a phase I inter-patient dose escalation open labeled study assessing multiple doses of CYT107 in patients of at least 15 years of age, who are recipients of HLA matched ex vivo T cell depleted bone marrow or peripheral blood stem transplants.

The dose escalation design is aimed at establishing the absence of significant toxicity and to define a biologically active dose in this patient population.

At each dose level, eligible patients will receive 3 doses of CYT107 injected subcutaneously (under the skin of the arm, legs, or stomach) once a week for 3 weeks.

Groups of three patients will be entered at each dose level of CYT107. Three dose levels are planned: 10 mcg/kg/week, 20 mcg/kg/week and 30 mcg/kg/week. Three patients must complete day 42 of the study at a dose level without a dose limiting toxicity (DLT) before there is escalation to the next dose level.

Conditions

Interventions

DRUG

CYT107 - Recombinant glycosylated human interleukin 7.

Patients will be treated with CYT107 60 to 210 days post transplantation, in 3 successive cohorts of 3 patients. Escalating doses of CYT107 will be given to successive cohorts. Patients will receive 1 dose of CYT107 by the subcutaneous route, once a week for 3 weeks. Dose level 1: 10 mcg/kg/dose for 3 doses; Dose level II: 20 mcg/kg/dose for 3 doses; Dose level III: 30 mcg/kg/dose for 3 doses. Only 1 treatment course for this initial study.

DRUG

rhIL-7 (CYT107)

10, 20, or 30 mcg/kg once a week for 3 consecutive weeks via the subcutaneous route.
