Enterococcus faecium is a difficult-to-treat pathogen with emerging resistance to most clinically available antibiotics. Daptomycin (DAP) is the standard of care, but even high DAP doses (12 mg/kg body weight/day) failed to eradicate some vancomycin-resistant strains. Combination DAP-ceftaroline (CPT) may increase β-lactam affinity for target penicillin binding proteins (PBP); however, in a simulated endocardial vegetation (SEV) pharmacokinetic/pharmacodynamic (PK/PD) model, DAP-CPT did not achieve therapeutic efficacy against a DAP-nonsusceptible (DNS) vancomycin-resistant E.
