A Study of IL-7 to Restore Absolute Lymphocyte Counts in Sepsis Patients

Summary

A multicenter, randomized, double-blinded, placebo-controlled study of two dosing frequencies of recombinant Interleukin-7 (CYT107) treatment to restore absolute lymphocyte counts in sepsis patients; IRIS-7B (Immune Reconstitution of Immunosuppressed Sepsis patients). A parallel study will be performed in France to allow a common statistical analysis of the primary end points and analysis for the enrolled patient population.
