Brief summary
The purpose of this study is to assess the safety and efficacy of doripenem in participants with nosocomial pneumonia (inflammation of the lungs in which the lungs become heavy; pneumonia occurring at least 48 hours after hospital admission), complicated intra-abdominal (in belly) infections and complicated urinary tract infections (bladder infections).
Detailed description
This is an open-label (all people involved know the identity of the intervention), multi-center (conducted in more than 1 center) study, to evaluate the safety and effectiveness of doripenem in treating Thai participants with nosocomial pneumonia, complicated intra-abdominal and urinary tract infections. The study consists of 4 visits: Visit 1 (Baseline), Visit 2 (End-of-Treatment \[EOT\], up to Day 14), Visit 3 (Phone visit, Test-of-Cure \[TOC\], up to Day 14 after EOT) and Visit 4 (Phone visit, Day 90). Participants will receive 500 milligram (mg) of doripenem as intravenous infusion (directly into the vein) every 8 hours for at least 3 days after clinical response and extended up to 14 days. Efficacy will primarily be evaluated by determination of clinical response. Participants' safety will be monitored throughout the study.
Interventions
Doripenem 500 mg will be administered as 1 or 4 hours intravenous infusion, after every 8 hours up to maximum of 14 days.

Outcome results
Number of Participants With Adverse Events (AEs) and Number of Participants Discontinued Because of AEs
An adverse event is any untoward medical occurrence in a participant administered with a pharmaceutical product. An adverse event does not necessarily have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. The number of participants discontinued because of AEs were also reported.
Time frame: Up to 30 days after last dose of study drug
Population: Intent-to-treat population (ITT) included all participants who received at least one dose of study medication.
