Safety & Efficacy of True Human Antibody, 514G3, in Staphylococcus Aureus Bacteremia Hospitalized Subjects.

This study is a Phase I/II, double-blind, placebo-controlled trial investigating the True Human monoclonal antibody 514G3 in subjects hospitalized with Staphylococcus aureus bacteremia. Phase I involves dose escalation to evaluate potential toxicity and establish the recommended phase 2 dosage of 514G3. In Phase II (dose expansion), eligible subjects will be randomized at a ratio of 2:1 to receive either a single dose of 514G3 with standard IV antibiotic therapy or a single dose of placebo with standard IV antibiotic therapy, aiming to assess safety and tolerability. The trial aims to determine the safety, efficacy, and optimal dosage regimen of 514G3 in these hospitalized subjects.
