Clinical Trial Summary

The purpose of this study is to characterize the Pharmacokinetic and to confirm the popPK model derived from healthy volunteers in hospitalized adults who are infected with respiratory syncytial virus (RSV) and to determine in adults who are hospitalized with respiratory syncytial virus (RSV) infection 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) assay.

Description:

The study will be conducted in 3 phases: a screening phase, a treatment phase from Day 1 to Day 5/6 (depending on the timing of the loading dose), and a follow-up phase for a total of 28 days post randomization. Participants will have assessments completed at Day 7, Day 10, Day 14, and Day 28. Depending on discharge date, assessments will be completed either while hospitalized or during outpatient visits. The duration of the participant's participation will be approximately 28 days. The study will be performed in 2 parts. Participants will be randomly assigned to one of 2 treatment groups in part 1, and to one of 3 treatment groups in part 2. Treatment groups will be evaluated for PK and safety after a target of approximately 24 participants have been enrolled in part 1 and before initiating part 2 (approximately 90 participants in part 2). An Independent Data Monitoring Committee (IDMC) will be established to monitor the safety of participants and will review data in an unblinded manner on a regular basis to ensure the continuing safety of the participants enrolled in this study and to evaluate whether efficacy objectives are met. The committee will meet periodically to review interim data. Based on the recommendations of the IDMC following interim analyses/reviews, an increase in duration may be implemented.

Primary	Least Square Mean Difference (Low and High Dose Lumicitabine Versus Placebo) of Respiratory Syncytial Virus (RSV) Ribonucleic Acid (RNA) Viral Load Area Under the Concentration-time Curve From Day 1 to 7 (AUC[1-7])	RSV RNA viral load in log10 copies/milliliter/day (log10 copies/mL/day) was measured in mid-turbinate nasal swabs and in endotracheal samples (obtained from intubated participants or via suction through tracheostomy or other sampling methods) using quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Due to early termination of study, the analysis was not conducted as planned. Instead, using the same specification as for the primary analysis, a comparison was made on the AUC(1-7) days of pooled active treatment groups versus pooled placebo. The comparison was done as planned using a mixed model for repeated measures, using all available viral load data of baseline up to and including Day 7. The model computes the AUC at group level based on all available data, taking missing data into account under the missing at random assumption. The table reports the planned difference versus (pooled) placebo. No adjustment for multiplicity was applied.	Day 1 (Baseline) to 7
