Recombinant Interleukin-7 (CYT107) to Restore Absolute Lymphocyte Counts in Sepsis Patients

Lymphopenic sepsis Patients will be randomized 3:1 to receive either: a) Intravenous (IV) administration of CYT107 at 10 μg/kg twice a week for 3 weeks or b) IV placebo (normal saline). The effect of CYT107 on Lymphocyte and various T cell populations will be documented with a focus on the first 29 days. Stopping rules will apply if ALC increases to \>2.5 times the upper limit of normal range. The IRIS-7C \& D studies will be conducted at multiple sites in France and the United States. All sites will use the same study design and similar study protocol for a common statistical analysis of 40 evaluable participants.
