5.1 Increased Mortality in Ventilator-Associated Bacterial Pneumonia
  • In a clinical trial of patients with ventilator-associated bacterial pneumonia comparing doripenem to imipenem, more subjects receiving doripenem died 23% (31/135) compared to those receiving imipenem 16.7% (22/132) based on 28-day all-cause mortality in the intent-to-treat (ITT) population. Clinical response rates were also lower in the doripenem arm. Doripenem is not approved for the treatment of ventilator-associated bacterial pneumonia.
