Inclusion Criteria

1. Subject is ≥50 years of age.
2. Female subjects of non-childbearing potential (i.e., surgically sterilized, post-menopausal [amenorrhea for 1 year confirmed by negative hormone panel]) who also have a negative pregnancy test at screening.
3. Male subjects must be either surgically sterilized (e.g., post-vasectomy or orchiectomy) or willing to adhere to the study’s contraceptive requirements. Male subjects’ female partner(s) must be surgically sterilized or post-menopausal (amenorrhea for 1 year) or their female partner(s) of child-bearing potential must be willing and able to adhere to the contraceptive requirements.
4. Each subject or their legal guardian must sign an informed consent form (ICF) indicating that he or she understands the purpose of and procedures required for the study and is willing to participate in the study before starting any screening activities.
5. Subject has a positive RT-PCR test result for RSV at the time of screening.

NOTE: Co-infection with other acute viruses or bacteria is permitted.
6. Subject has been, or will be, admitted to the hospital for an acute respiratory illness with signs and symptoms consistent with a viral infection (e.g., fever, cough, nasal congestion, runny nose, sore throat, myalgia, lethargy, shortness of breath, or wheezing) with onset <7 days from the anticipated time of randomization.

NOTE: The viral infection may present in any way so long as the underlying precipitant of the illness is considered by the PI to be due to RSV infection. Examples of such an illness
include:
• An upper or lower viral respiratory tract infection (e.g., flu-like illness”)
• Pneumonia
• Respiratory distress
• Asthma exacerbation
• COPD exacerbation

Exclusion Criteria

Subjects will be ineligible for this study if they meet any one of the following criteria:
1. Subject is undergoing peritoneal dialysis, hemodialysis or hemofiltration or has an estimated glomerular filtration rate (GFR, determined by Cockcroft-Gault Formula) <30 mL/min.

Cockcroft-Gault Formula
CCr = (140 – age) × Mass (kg) × (0.85 if female)
72 * Creatinine Clearance (mg/dL)
CCr = (140 – age) × Mass (kg) × K
Serum Creatinine (μmol/L)
Where K = 1.23 if male; 1.04 if female
NOTE: The independent data monitoring committee (IDMC) may lower the exclusionary GFR limit to <15 mL/hr if emerging PK data in subjects with GFR ≥30 mL/min suggest that ALS-008112 and ALS-008144 exposures in the setting of severe (i.e., GFR ≥15-<30 mL/hr) renal impairment are projected to remain within an acceptable range.
2. Subject has presence of any concurrent illness, including laboratory, vital sign, ECG, or physical exam findings, or medical history that, in the opinion of the investigator, would place the subject at an unreasonably increased risk as a result of participation in this study.
3. Subject reports receiving an investigational drug or vaccine within 30 days, or 5 half-lives (whichever is longer) prior to the planned first dose of study drug.
4. Subject has a known history of human immunodeficiency virus (HIV) or chronic, active hepatitis infection.
5. ALT >3×ULN AND bilirubin >2×ULN (direct >35%) OR ALT>5×ULN
6. Subjects who have been hospitalized for >72 hours at the time of randomization.
7. Subjects anticipated to be hospitalized for <24 hours after randomization.
8. Subjects who are not expected to survive for <48 hours.
9. Recent (<14 days) use, or anticipated use during conduct of the study, of concomitant medications (prescription and non-prescription) which are inhibitors or substrates of the OAT3 transporter.
10. Treatment of the current illness with drugs specifically targeting the RSV infection itself
(e.g., RSV immunoglobulin, ribavirin, palivizumab). Medications treating the sequelae of the RSV infection or any concurrent illness are permitted if not otherwise excluded.
11. Subjects unwilling to undergo regular nasal swab procedures or with any physical abnormality which limits the ability to collect regular nasal specimens.
12. Subjects that are considered by the investigator to be immunocompromised over the past 12 months, whether due to underlying medical condition (e.g., malignancy or genetic disorder) or medical therapy (e.g., medications, chemotherapy, radiation, stem cell or solid organ transplant).
NOTE: The acute use of corticosteroids (inhaled or systemic) is permitted; chronic (>28 day) use of corticosteroids is permitted for prednisone doses ≤20 mg (or equivalent).
13. Subjects unable to take medications enterally (e.g., orally or via nasogastric or PEG tube) or a known gastrointestinal-related condition that may interfere with study drug absorption.
14. Female subject that is pregnant or breastfeeding
15. In the investigator’s opinion, the subject is unwilling or unable (e.g., due to concomitant medical conditions) to comply with protocol requirements, instructions, and protocol stated restrictions, and is unlikely to complete the study as planned.
16. Subject has known or suspected hypersensitivity to the study drug or its excipients (microcrystalline cellulose, mannitol, croscarmellose sodium,
