Clinical and Economic Outcomes of Ceftaroline Fosamil for ABSSSI Documented or at Risk of MRSA

Phase 4

Completed

• Conditions: Staphylococcal Skin Infections; Skin Diseases, Infectious
• Interventions: Drug: Ceftaroline; Drug: Vancomycin

• Registration Number: NCT02582203
• Lead Sponsor: Wayne State University

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Ceftaroline	Ceftaroline	600 mg IV (over 1 hour) every 12 hours for renal function \> 50 mL/min, adjusted for renal function based on package insert for no more than 14 days.
Vancomycin	Vancomycin	Dosed by institutional pharmacy protocol to reach goal trough level of 10 - 20 mg/L steady state concentration for no more than 14 days.

Primary Outcome Measures

Name	Time	Method
