- Janssen Research & Development, LLC
- Brief Summary
The purpose of this study is to evaluate the antiviral activity, clinical outcomes, safety, tolerability, and pharmacokinetic/pharmacodynamic relationships of different oral dose levels of JNJ-53718678 in children greater than or equal to 28 days and less than or equal to 3 years of age with respiratory syncytial virus (RSV) disease (hospitalized participants \[Cohort 1\] or outpatients \[Cohort 2\]).
- Detailed Description
JNJ-53718678 is an investigational respiratory syncytial virus (RSV) specific fusion inhibitor and is under development for the treatment of RSV infection, which results in an upper and/or lower respiratory tract illness. The primary hypothesis of this study is that JNJ-53718678 has antiviral activity against RSV (that is, results in a decrease in RSV nasal viral load from immediately prior to first dose of study drug until Day 5). This will be assessed by a positive dose-response relationship of JNJ-53718678 compared to placebo. Besides the RSV nasal viral load through day 5, other timepoints will also be evaluated as well as other nasal viral load related parameters. In addition, the evolution of signs and symptoms of RSV disease will be evaluated. Participants' safety will be monitored throughout the study by evaluating the occurrence and severity of adverse events and by laboratory and electrocardiogram measurements. Study participants will be identified when they are hospitalized or expected to be hospitalized within 24 hours after presentation to the hospital (Cohort 1) or present for medical care as outpatients (Cohort 2) with symptoms of an acute respiratory illness supporting a diagnosis of RSV infection. Eligible participants will be randomized 1:1:1 to receive either a low or a high dose of JNJ 53718678 or placebo and will be receiving study treatment for 7 days. They will be followed up for 3 weeks after the last dose. The total study duration for each participant will be approximately 29 days.

- Primary Outcome Measures
Name Time Method Respiratory Syncytial Virus (RSV) Viral Load Area Under Curve (AUC) From Immediately Prior to First Dose of Study Drug (Baseline) Through Day 5 (AUC[Day 5]) Baseline through Day 5 RSV viral load AUC from immediately prior to first dose of study drug through Day 5 was determined. The RSV viral load was measured by quantitative reverse transcription polymerase chain reaction (qRT-PCR) assay in mid-turbinate nasal swab specimens. As planned, combined data for both the cohorts was collected, analyzed and reported for this outcome measure.
- Secondary Outcome Measures
Name Time Method RSV Viral Load Over Time Baseline, Days 3, 5, 8, 14, and 21 RSV viral load actual values over time were measured by qRT-PCR in the nasal swab specimens collected at the clinic visits and at home. As planned, combined data for both the cohorts was collected, analyzed and reported for this outcome measure.
Change From Baseline in RSV Viral Load Over Time Baseline up to Days 3, 5, 8, 14, and 21 Change from baseline in RSV viral load over time was measured by qRT-PCR in the nasal swab specimens collected at the clinic visits and at home. As planned, combined data for both the cohorts was collected, analyzed and reported for this outcome measure.
Least Squares (LS) Mean RSV Viral Load on Days 3, 8 and 14 Baseline through Days 3, 8, and 14 LS mean RSV viral load on Days 3, 8, and 14 was reported. LS mean viral load (log10 copies/mL) was estimated per time point. The difference in RSV viral Load AUC (log10 copies\*day/mL) from immediately prior to first dose of study drug (baseline) through Day 3, 8 and 14 was determined from the model estimating the LS Mean Viral Load per time point, and is presented in the statistical analysis. The RSV viral load was measured by qRT-PCR assay in mid-turbinate nasal swab specimens. As planned, combined data for both the cohorts was collected, and analyzed for this outcome measure at Days 3 and 8, however combined Cohort 1 and Cohort 2 data were not analyzed for this outcome measure at Day 14, due to the premature study termination.
Time to Undetectable RSV Viral Load Up to Day 21 Time to undetectable RSV viral load (as measured by qRT-PCR) was defined as the time in hours from first dose of study drug to first post-baseline timepoint at which the virus was undetectable and after which there were no more detectable virus assessments.
