Official Title
Impact of Incorporating Metagenomic Next-generation Sequencing in the Management of Pneumonia on Diagnostic Efficiency and Outcomes: A Randomized Controlled Trial
Brief Title
Metagenomic NGS for Diagnosis of Pneumonia
Protocol ID
NCT05979350
Lead Sponsor
National Taiwan University Hospital
Brief 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.
Detailed 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.
