A Study in Belgian Children Hospitalized With Respiratory Syncytial Virus Related Acute Respiratory Infections

Janssen Research & Development, LLC62 enrolled

Overview

The purpose of the study is to assess viral kinetics and clinical symptoms kinetics in pediatric patients hospitalized with Respiratory Syncytial Virus (RSV) confirmed lower respiratory tract infection (LRTI).

This is an exploratory prospective study (a study in which the patients are identified and then followed forward in time for the outcome of the study). The study will consist of two phases: a screening phase (Day 1) and an assessment phase (Day 2 to Day 7). During screening phase, in pediatric patients hospitalized with LRTI and from whom the informed consent form was obtained, diagnosis of RSV infection will be performed within 24h from the hospital admission, using a SOFIA POC test on nasal specimens. During the assessment phase the collection of nasal specimens will be done daily for a maximum of 6 days (Day 2 to Day 7 of hospitalization) or until patient discharge from hospital. Approximately 50 patients will be enrolled in this study. The total duration of the study for each participant will be approximately 7 days. The study duration will extend during 1-3 RSV epidemic seasons, or until the targeted number of 50 RSV hospitalized children have completed the study.

Outcomes

Primary Outcomes

Rate of Respiratory Syncytial Virus (RSV) Viral Clearance

RSV viral clearance, defined as the change in log viral load (VL) from Day 1 to Day 3, where the VL is measured in nasal specimens with quantitative reverse transcript poly cycle reaction (qRT-PCR).

Time frame: Day 1 to Day 3

Secondary Outcomes

Change From Baseline in Clinical Symptoms Score (CSS)

The severity of the RSV disease will be assessed using CSS. CSS will be computed based on clinical parameters (O2 saturation, heart rate, respiratory rate) and lung auscultation examination. CSS score ranges from 0 (best) to 15 (worst). Higher scores indicate worsening.

Time frame: Day 1 (baseline) to Day 3

Change From Baseline in Medical Support Score (MSS)

The severity of the RSV disease will be assessed using MSS. MSS will take into account the use of supplementary oxygen, the request for mechanical ventilation, intensive care unit admission and the length of hospitalization. The MSS score ranges from 0 (best) to 5 (worst). Higher scores indicate worsening.

Time frame: Day 1 (baseline) to Day 3
