802 participants in 2 patient groups

Ceftaroline fosamil

Experimental group

Description:

Patients will receive 600 mg of ceftaroline fosamil administered as a 120-minute intravenous infusion very 8 hours. Each dose will be infused in a volume of 250 mL over 120-minutes followed by aztreonam placebo in a volume of 100 mL infused over 30 minutes every 8 hours. In addition vancomycin placebo will be given in a volume of 250 mL infused over 120 minutes every 12 hours. Doses will be adjusted according to the patient's renal function.

Treatment:

Drug: Ceftaroline fosamil

Vancomycin plus aztreonam
