Respiratory Syncytial Virus Infections
Conditions
Brief summary
The purpose of this study is to explore the antiviral effect of JNJ-53718678 at 2 dose levels (80 milligrams \[mg\] and 500 mg) once daily for 7 days in adults with Respiratory Syncytial Virus (RSV) infection, as measured by RSV viral load in nasal secretions by quantitative reverse transcription polymerase chain reaction (qRT-PCR) assay.
Detailed description
This study will be performed to explore the antiviral activity, clinical outcomes, safety, tolerability, and pharmacokinetics of JNJ-53718678 in adult participants infected with RSV. The study will include both participants who are otherwise healthy (ie, without underlying condition) or who have comorbid conditions (eg, asthma, chronic obstructive pulmonary disease (COPD), cardiovascular disease, other chronic diseases), with the exception of immunocompromised participants, presenting for medical care but not requiring hospitalization. The study will include a screening period (Day -1 to Day 1), a treatment Period (Day 1 to Day 8), and a follow-up period (Day 9 to Day 28). Safety evaluations will include adverse events, laboratory tests, electrocardiogram, vital signs, physical examination, and specific toxicities.
Interventions
Participants will receive 500 mg dose of JNJ-53718678 oral solution once daily for 7 days.
Participants will receive 80 mg dose of JNJ-53718678 oral solution along with the matching placebo to the same total volume as for the 500 mg dose once daily for 7 days.
In treatment B, participants will receive matching placebo along with JNJ-53718678 to maintain the same total volume as for the 500 mg dose once daily for 7 days. In treatment C, participants will receive matching placebo to the same total volume as for the 500 mg dose once daily for 7 days.

Number of Participants With Worst Treatment-Emergent Laboratory Abnormalities
Number of participants with worst treatment-emergent laboratory abnormalities (serum chemistry, hematology and urinalyses) were reported based on DMID toxicity grading scale. DMID toxicity grade categorized as Grade 1=mild(mild discomfort (\< 48 hours); no medical intervention/therapy required), Grade 2= moderate (Moderate Mild to moderate limitation in activity - some assistance may be needed; no or minimal medical intervention/therapy required), Grade 3= severe (severe Marked limitation in activity, some assistance usually required; medical intervention/therapy required, hospitalizations possible), and Grade 4=life threatening (extreme limitation in activity, significant assistance required; significant medical intervention/therapy required, hospitalization or hospice care probable).

Severity of Signs and Symptoms of RSV Assessed by Respiratory Infection-Patient Reported Outcomes (RI-PRO) Questionnaire
The severity of signs and symptoms of RSV infection was assessed using the RI-PRO questionnaire. The RI-PRO questionnaire is 32-item questionnaire. It summarizes severity of 6 symptom domains: nose (4 items), throat (3 items), eyes (3 items), chest/respiratory (7 items), gastrointestinal (4 items), and body/systemic (11 items). Each RI-PRO domain score ranges from 0 (symptom free) to 4 (very severe symptoms). Domain scores were calculated as the arithmetic mean of the scores for items within the domain.
Time frame: Baseline, Days 3, 5, 8, 14 and 21
Population: The ITT-i population consisted of all randomized participants who received at least 1 dose of study drug and who had a central lab-confirmed RSV infection. Here 'N' (number of participants analyzed) signifies number of participants who were evaluable for this outcome measure.

Time to Resolution of Key RSV Symptoms as Assessed by RI-PRO Questionnaire
Time to resolution of key RSV symptoms (congested or stuffy nose, sore or painful throat, trouble breathing, chest tightness, coughing, coughed up mucus or phlegm, weak or tired) as assessed by RI-PRO questionnaire was reported. Resolution of RSV symptoms was defined as a score of 'Not at all/symptom free' (score = 0) or 'A little bit' (score = 1) for at least 24 hours for symptoms of the RI-PRO questionnaire. The RI-PRO questionnaire is 32-item questionnaire. It summarizes severity of 6 symptom domains: nose (4 items), throat (3 items), eyes (3 items), chest/respiratory (7 items), gastrointestinal (4 items), and body/systemic (11 items). Each RI-PRO score ranges from 0 (symptom-free) to 4 (very severe symptoms).
Time frame: Up to Day 21
Population: The ITT-i population consisted of all randomized participants who received at least 1 dose of study drug and who had a central lab-confirmed RSV infection. Here 'N' (number of participants analyzed) signifies number of participants who were evaluable for this outcome measure.

Time to Return to Usual Activity/Health Based on RI-PRO Questionnaire
Time from the first dose of study drug until the time to return to usual activity/health was determined. Return to usual activity/health when the response is 'Yes' on RI-PRO additional question 7 ('Have you returned to your usual activity/health today?') for at least 24 hours.
Time frame: Up to Day 21
Population: The ITT-i population consisted of all randomized participants who received at least 1 dose of study drug and who had a central lab-confirmed RSV infection.
