Clinical and Economic Outcomes of Ceftaroline Fosamil for the Treatment of Acute Bacterial Skin and Skin Structure Infections Documented or at Risk of Methicillin-Resistant S. Aureus

The proposed study is a prospective, open-label, randomized, multi-center trial of ceftaroline versus vancomycin for the treatment of ABSSSI in patients documented or at risk for MRSA. Patients admitted to the Detroit Medical Center, Henry Ford Hospital, or St. John Medical Center in Detroit Michigan with a documented ABSSSI between April 2012 and November 2015 will be evaluated for inclusion. Patients must present with at least 3 of the following local signs/symptoms: pain, tenderness, swelling erythema, warmth, drainage/discharge, induration, and lymph node swelling/tenderness. Patients will be randomized 1:1 ceftaroline or vancomycin with optional anaerobic and/or Gram-negative coverage. The assignment of study drug will follow a randomized list that was previously generated via a computerized random mix block generator (nQuery Advisor® 7.0) and available at each of the study sites. Patients will be randomized to ceftaroline intravenously at 600 mg infused over 1 hour every 12 hours for patients with normal renal function. Patients randomized to vancomycin will receive the standard 15 mg/kg dose based on total body weight infused over 1 hour q 12 hour, dose and interval adjusted based on creatinine clearance and via institution-specific pharmacy protocol to target serum trough concentrations of 10-20 mg/L within the first 72 hours. Outcomes measured in the Clinically Evaluable patient population include day two or three size reduction (percentage) and clinical response at end of therapy or discharge.
