Abstract

Background: We 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.

Methods: Three 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.

Results: Clinical 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.

Conclusions: Ceftaroline 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.
