Metagenomic NGS for Diagnosis of Pneumonia

Status Not yet recruiting

Clinical Trial Summary

In this randomized controlled trial, we aim to evaluate the efficacy of incorporating mNGS in the management of pneumonia on efficiency and accuracy of causative pathogen identification, proportion of participants with effective antimicrobial therapy, length of hospitalization, and mortality.

Clinical Trial Description

This is an open-label, randomized, multi-center, phase 2 study that will evaluate the efficacy of incorporating mNGS in the management of severe pneumonia on accuracy and efficiency of achieving definite diagnosis of identifying causative pathogens of pneumonia, appropriate antimicrobial therapy and patient outcomes. The diagnosis of pneumonia requires radiological evidence of pneumonia and at least two of the following clinical criteria: new, or worsening cough, new or worsening expectoration of sputum, new or worsening dyspnea, hemoptysis, pleuritic chest pain, and fever (≥38.0°C). Severe pneumonia is defined as pneumonia with hypoxemia requiring orotracheal intubation and mechanical ventilation support. Written informed consent is needed from the eligible subjects or from their legal guardian at the time of recruitment. After completing informed consent, subjects will be randomized with a 1:1 allocation ratio via a web-based randomization system to receive standard of care (SOC) using culture and serology based work-up for pathogen detection or SOC with additional mNGS method using APGseq ® (Asia Pathogenomics, New Taipei City, Taiwan) for pathogen detection. The treatment for pneumonia is suggested following the Taiwan Guidelines for the Management of Pneumonia published in 2018. After randomization, the subjects will be followed until death, discharged from the hospital or 28 days after randomization whichever comes first. The total study duration is expected to be two years from the first subject enrolled to the final analysis. ;
