13 Summary & Conclusion • AP - SA02 phage cocktail safe and well tolerated • In combination with BAT, AP - SA02 had an earlier and higher cure rate compared to placebo in patients with complicated SAB at day 12, post BAT, and at EOS • AP - SA02 was assessed with clinical trends of earlier resolution, shorter hospitalization, and lack of relapse 4 weeks post - therapy • Results support proceeding to a Phase 3 RCT of this novel bacteriophage cocktail for SAB
