Brief Summary:
The purpose of this study is to determine in hospitalized infants and children who are infected with respiratory syncytial virus (RSV) the dose-response relationship of multiple regimens of lumicitabine on antiviral activity based on nasal RSV shedding using quantitative real-time reverse transcriptase polymerase chain reaction (qRT-PCR).

Condition or disease Intervention/treatment Phase
Respiratory Syncytial Viruses Drug: Lumicitabine Drug: Placebo Phase 2

Detailed Description:
RSV is a leading cause of lower respiratory tract disease in infants. Most infants and children who get RSV recover fully after 1-2 weeks, but RSV infection can sometimes worsen and may lead to hospitalization and admission into an intensive care unit. The main purpose of this study is to learn how well the study drug (lumicitabine, also known as JNJ-64041575 or ALS-008176) works, how the human body handles the study drug, which dose of the study drug is effective for treatment of RSV infection in infants/children and how safe it is compared to a placebo (placebo looks just like lumicitabine [given in same way] but has no effect against RSV). Approximately up to 180 participants aged between 28 days to 36 months and hospitalized with RSV infection will take part in this world-wide study.

Primary Outcome Measures :
  1. Area Under the Curve (AUC) of Respiratory Syncytial Virus (RSV) Viral Load [ Time Frame: Day 1 to 7: Predose, 0.25 and 2 hours postdose ]
    AUC of RSV viral load was measured by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) assay of the mid-turbinate nasal swab.


Secondary Outcome Measures :
  1. Number of Participants With Emergent Adverse Event [ Time Frame: Up to 28 days ]
    An adverse event (AE) is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. An AE can, therefore, be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product. All AEs reported during treatment or follow-up were considered emergent and were included in the analysis.

  2. Number of Participants With Clinically Significant Physical Examinations Abnormalities [ Time Frame: Up to 28 days ]

    The number of participants with emergent clinically relevant vital signs (temperature, pulse rate, respiratory rate, diastolic blood pressure, systolic blood pressure, oxygen saturation) abnormalities that emerged after treatment initiation reported. An abnormality was considered emergent in a particular phase if it is worse than baseline. If baseline is missing, the abnormality is always considered as emergent. A shift from 'abnormally low' at baseline to 'abnormally high' post baseline (or vice versa) was also emergent.
