The purpose of this study is to evaluate the safety, tolerability, efficacy and pharmacokinetics (PK) of CF-301 in addition to background standard of care (SOC) antibacterial therapy for the treatment of Staphylococcus aureus (S. aureus) bloodstream infections (bacteremia), including endocarditis in adults. Patients will be randomized to receive a single intravenous dose of CF-301 or placebo in addition to SOC antibacterial therapy. Patients will be prescribed standard of care antibiotics selected by the investigators based on their professional experience, practice guidelines and local antibiotic susceptibility information for the treatment of S. aureus bacteremia. CF-301 is a lysin and member of a new class of targeted protein-based antimicrobials that has demonstrated activity against S. aureus in laboratory (in vitro) and animal studies, alone and in addition to conventional antibiotics.
