    BackgroundWe conducted a meta-analysis of clinical trials of adults hospitalized with pneumonia outcomes research team (PORT) risk class 3-4 community-acquired pneumonia (CAP) receiving ceftaroline fosamil versus ceftriaxone.MethodsThree Phase III trials (clinicaltrials.gov registration numbers NCT00621504, NCT00509106 and NCT01371838) including 1916 hospitalized patients with CAP randomized 1:1 to empirical ceftaroline fosamil (600 mg every 12 h) or ceftriaxone (1-2 g every 24 h) for 5-7 days were included in the meta-analysis. Primary outcome was clinical response at the test-of-cure visit (8-15 days after end of treatment) in the PORT risk class 3-4 modified ITT (MITT) and clinically evaluable (CE) populations. Data were tested for heterogeneity (χ(2) test) and, if not significant, results were pooled and OR and 95% CI constructed. A logistic regression analysis assessed factors impacting cure rate and treatment interactions.ResultsClinical cure rates in each trial consistently favoured ceftaroline fosamil versus ceftriaxone, with no evidence of heterogeneity. In the meta-analysis, ceftaroline fosamil was superior to ceftriaxone in the MITT (OR: 1.66; 95% CI 1.34, 2.06; P < 0.001) and CE (OR: 1.65; 95% CI 1.26, 2.16; P < 0.001) populations. Results were consistent across various patient- and disease-related factors including patients' age and PORT score. Prior antimicrobial use within 96 h of starting study treatment was associated with diminished differences in cure rates between treatments.ConclusionsCeftaroline fosamil was superior to ceftriaxone for empirical treatment of adults hospitalized with CAP. Receipt of prior antimicrobial therapy appeared to diminish the observed treatment effect.© The Author 2015.
