PRIMARY outcome

Timeframe: TOC (7 to 14 days after the last dose of study medication therapy)

Population: Clinical Intent-To-Treat (CITT): All randomized participants who met the minimal disease definition of pneumonia regardless if a baseline pathogen was isolated from the baseline lower respiratory tract culture, pleural fluid or blood culture.

The participants were classified as cure if they had resolution or clinical improvement of signs and symptoms of pneumonia, favorable response at End of treatment for IV study (EIV) visit; had no fever; improvement or no progression of radiographic findings of pneumonia on chest X ray; improvement in oxygenation or discontinued mechanical ventilation in intubated participants; and not received nonstudy systemic antibacterial therapy for pneumonia.

SECONDARY outcome

Timeframe: EIV (within 24 hours after completion of the last dose of IV study medication therapy)

Population: Clinical intent-to-treat: All randomized participants who met the minimal disease definition of pneumonia regardless if a baseline pathogen was isolated from the baseline lower respiratory tract culture, pleural fluid or blood culture.

Participants were considered as clinical improved if they had no fever, clinical improvement in signs and symptoms of pneumonia from baseline, decrease in WBC, improvement or lack of progression of radiographic findings in comparison with the screening chest X-ray, and not received any nonstudy systemic antibacterial therapy for the treatment of pneumonia after IV study drug therapy had begun.

Population: Clinical Intent-to-Treat (CITT): All randomized participants who met the minimal disease definition of pneumonia regardless if a baseline pathogen was isolated from the baseline lower respiratory tract (LRT) culture, pleural fluid or blood culture.

The participants were classified as clinical cure if all pretreatment signs and symptoms showed no evidence of resurgence after administration of the last dose of study medication and no nonstudy systemic antibacterial therapy was given for the treatment of pneumonia.

Timeframe: EIV (within 24 hours after completion of the last dose of IV study medication therapy), TOC (7 to 14 days after the last dose of study medication therapy), and LFU (28 to 42 days after the last dose of study medication therapy)

Population: Microbiological intent-to-treat - Participants of CITT with at least one baseline pneumonia pathogen from pleural fluid, LRT, or blood culture susceptible to doripenem and cefepime. 3 and 2 participants from doripenem and cefepime, respectively had no susceptible pneumonia pathogens at baseline and were excluded from this set.

Favorable per-participant microbiological response rate was evaluated at the at End of IV (EIV) visit, Test Of Cure (TOC) visit, and Late Follow-Up (LFU) visit. The favorable per-participant microbiological response was considered when all baseline pathogens were eradicated (absence) or presumed eradicated (absence of material to culture in a participant who has a positive clinical response to treatment).

A total of 3 pathogens were isolated at baseline from lower respiratory tract (LRT) culture in 2 participants in the doripenem treatment group and were susceptible to the study drug received: 2 pathogens (Staphylococcus aureus Klebsiella pneumoniae) were isolated at baseline from 1 participant and a 3rd pathogen (Streptococcus pneumoniae) was isolated at baseline from the other participant (see listed in the table below; the number in parenthesis next to each pathogen represent the number of participants with the pathogen isolated at baseline in the doripenem treatment group). The favorable per-participant microbiological response was considered when all baseline pathogens were eradicated (absence) or presumed eradicated (absence of material to culture in a participant who has a positive clinical response to treatment). NOTE: No participants in the cefepime treatment group met criteria for inclusion in the Microbiological intent-to-treat analysis.
