GM-CSF for Reversal of immunopAralysis in pediatriC sEpsis-induced MODS Study

This study is an open-label, multi-center, interventional trial in which children with sepsis-induced MODS undergo surveillance immune function testing beginning on Day 2 of MODS. Those children who demonstrate immunoparalysis (TNF-alpha response \=200 pg/ml) by the morning after the 3rd scheduled dose with persistent resolution of immunoparalysis on the morning after the 7th scheduled dose. Resolution of immunoparalysis in 8 out of the first 10 subjects in a study treatment arm represents a successful dose and route. The goal of this study will be achieved through the following Specific Aims: Specific Aim 1. Establish the immunologic efficacy of GM-CSF administered by the IV and SQ routes in children with immunoparalysis in the setting of sepsis-induced MODS. Specific Aim 2. Estimate the pharmacokinetic parameters by the IV and SQ GM-CSF administered in pediatric sepsis-induced MODS. Specific Aim 3. Demonstrate the feasibility of screening, enrollment, drug delivery, and sample collection for a multi-center immunostimulation trial in children with sepsis-induced MODS.
