Zinforo®: High clinical cure rate and evidence of rapid response in CAP

Clinical cure rates: ASIA CAP2​​​​​​​

Study design

A Phase III, prospective, multicentre (China, Taiwan, Korea, Vietnam and India), randomised, double-blind, non-inferiority with nested superiority trial comparing Zinforo (600 mg IV every 12 hours) vs ceftriaxone (2 g IV every 24 hours)

Patient population

Adult Asian patients ≥18 years of age with PORT risk class III-IV CAP. 763 patients were treated for 5-7 days and evaluated in the MITT population

Study objective

To determine non-inferiority (with nested superiority) in the clinical cure rate of Zinforo compared with ceftriaxone (2 g) in the CE population at TOC (8-15 days after end of treatment)

Secondary objectives

Clinical response at the TOC in the MITT, mMITT, and ME populations; clinical response at EOT; clinical relapse at the LFU visit in patients who were clinically cured at TOC; microbiological response at the TOC; clinical and microbiological response by pathogen at the TOC; and safety (as assessed by adverse events in the safety population)
Clinical cure was defined as total resolution of all signs and symptoms of CAP or improvement to such an extent that further antimicrobial treatment was unnecessary

Zinforo 600 mg every 12 hours demonstrated superior efficacy vs ceftriaxone 2 g every 24 hours in terms of clinical cure rates2

Non-inferiority was defined as a lower limit of the 95% CI ≥–10% for the between group difference. If this was achieved the protocol stated superiority would be concluded if the lower limit of the 95% CI ≥0%.2

The safety profile of Zinforo was similar to that observed in the pooled Phase III CAP and cSSTI studies.2-4

**Zinforo is not active against Pseudomonas aeruginosa. Like other cephalosporins, Zinforo is not active against ESBL-producing strains. In vitro activity does not always correlate with clinical efficacy.1​​​​​​​
