A Study of Rilematovir in Adult patients with Respiratory Syncytial Virus (RSV) Infection

Phase 2
Conditions
Respiratory disorder, unspecified,
Registration Number
CTRI/2022/01/039085
Lead Sponsor
Janssen Research Development LLC
Brief Summary

The purpose of this study is to evaluate the efficacy of rilematovir compared to placebo with respect to the time to resolution of respiratory syncytial virus (RSV) lower respiratory tract disease (LRTD) symptoms.Rilematovir is an investigational RSV specific fusion inhibitor currently in development for the treatment of RSV infection in both adult and pediatric populations. The study will include a Screening period (Day -1 to Day 1), a Treatment period (Day 1 to Day 7/8 [depending on timing of first dose]), and a Follow-up period (Day 8/9 to Day 35). The total study duration of the study for each participant will be up to 35 days. The study will evaluate efficacy and safety of RSV in adult outpatients (18-85 years) who are at high risk of RSV related disease progression and have at least moderate RSV disease. The efficacy assessments include evaluation with electronic patient-reported outcome (ePRO) and the safety assessments include evaluations of physical examinations, vital signs, electrocardiograms, clinical laboratory tests, and adverse events.

Inclusion Criteria

Presented to the healthcare facility with symptoms suggestive of a diagnosis of acute respiratory syncytial virus RSV infection Has at least 2 symptoms of lower respiratory tract disease LRTD one of which must be scored as at least moderate if the symptoms did not pre-exist before RSV onset or one of which is scored worse than usual if the symptoms preexisted Tested positive for RSV infection using a molecularbased diagnostic assay polymerase chain reaction PCR or other on a bilateral nasal midturbinate swab sample Has at least one of the following high risk conditions that predispose them to RSVrelated disease progression a age greater than or equal 65 years b congestive heart failure CHF c chronic obstructive pulmonary disease COPD dasthma Randomized to study intervention treatment within 72 hours after onset of any of the RSV symptoms or worsening of pre existing symptoms Not be hospitalized during screening emergency room or hospital observation status for an anticipated duration of less than 24 hours are not considered as hospitalization.
