Introduction • Current agents approved for therapy of MRSA pneumonia – Vancomycin (VAN) – Linezolid – Quinupristin/dalfopristin – Teicoplanin • Telavancin (TLV) – Novel lipoglycopeptide with a multifunctional mechanism of action – Highly active in vitro against MRSA. – Activity unaffected by pulmonary surfactant – Studied in two double-blind, randomized trials for hospital-acquired pneumonia • Comparator agent: VAN • VAP accounted for substantial fraction of subjects • Primary endpoint clinical cure in all treated and clinically evaluable (CE) population in each study • Secondary endpoint superiority in pooled MRSA CE subpopulation

Telavancin HAP Study Design • Interventions – TLV 10 mg/kg, IV, once daily – VAN 1gm, IV q 12 hrs with dose adjustments per local protocol • Endpoints – 1º: Clinical response at follow-up visit (7-14 d post EOT) – 2º: 28 day mortality – 2º: Adverse event rates • Statistical analysis – Univariate comparisons as appropriate – Logistic regression to control for baseline covariates

Results • Pooled trials included 1503 subjects – 28% with VAP • Overall, TLV non-inferior to VAN for clinical response – MAT • TLV 57.5% vs. VAN 56.1%; Diff 1.2% (95% CI -4.7%, 7.2%) – CE • TLV 82.4% vs. VAN 80.7%; Diff 1.7% (95% CI -4.3%, 7.7%) • All-cause mortality revealed no significant difference: – TLV 20.0% vs. VAN 18.6%; Diff 1.4% (95% CI -2.6%, 5.3%)

Objectives – Subgroup Analysis The objective of this post-hoc analysis was: • To describe outcomes in patients with S. aureus (MRSA) VAP treated with TLV vs. VAN • To explore the safety and tolerability of TLV in subjects with S. aureus VAP

Subgroup Analysis • Subjects – VAP (defined as new radiographic infiltrate with appropriate signs and symptoms in persons receiving at least 3 calendar days of MV) – Microbiologic evidence of SA infection (respiratory culture or blood culture) • Analysis Populations – Modified all treated (MAT) • Met entry criteria and had pathogen isolated at enrollment – Modified all treated with monomicrobial infection (MATm) • Sensitivity analysis to control for variability of Gram-negative pathogens, and Gram-negative coverage in mixed infections

Review of Renal Events in HAP Studies • All serious renal events were subjected to blinded review for attribution to study medication by panel of independent nephrologists – All cases had numerous co-morbidities and received other potentially nephrotoxic drugs more likely to be associated with renal dysfunction • Overall, only 2 cases in each treatment group found to be possibly associated – Only 1 of 6 TLV cases . DC, judged to be possibly related to study med • TLV renal events . DC, all completely recovered by last visit; persistent in one VAN patient

Conclusions • TLV has comparable efficacy to VAN for SA VAP and for MRSA VAP • Potential difference in MRSA suggests more research in this area warranted • TLV generally well tolerated in this severely ill population • More efforts needed to understand renal interactions • TLV represents promising agent for SA VAP

Introduction • Ventilator-associated pneumonia (VAP) – Associated with significant morbidity and mortality – Increases duration of mechanical ventilation (MV) and hospital costs – Focus of quality efforts in US hospitals • Staphylococcus aureus (SA) – Leading pathogen in many hospital-acquired infections – Accounts for nearly 20% of all VAP in the US – Approximately 60% of SA VAP in US ICUs are due to methicillin-resistant (MRSA)
