| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
• To describe the safety and tolerability of CF-301 vs. placebo in addition to SOC antibacterial therapy for the treatment of patients with S. aureus BSIs including right-sided endocarditis.

 • To describe the PK parameters of CF-301. | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
• To estimate clinical outcome at Day 7 after CF-301/placebo administration, at the end of SOC antibacterial therapy (EOT), and at test-of-cure (TOC) 28 days after the EOT.
 • To estimate microbiological response at Days 7 and 14 after CF-301/placebo administration.
 • To estimate microbiological outcome at EOT and at TOC |
