Ages Eligible for Study: | 28 Days to 36 Months (Child) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Male or female who is either ≥6 months to ≤36 months (for Age Group 1) or ≥28 days to <6 months (for Age Group 2), defined at the time of randomization. Subjects in Age Group 2 must have been born ≥29 weeks of gestation to be eligible.
- Subjects diagnosed with RSV infection
- Subjects with signs of an acute respiratory illness with onset ≤7 days before the time of signing the ICF
- In the Investigator's opinion, the subject's caregiver understands and is able to comply with protocol requirements, instructions, and protocol-stated restrictions, and the subject is likely to complete the study as planned
Exclusion Criteria:
- Use of or anticipated need for invasive mechanical ventilation, cardiopulmonary bypass, hemodialysis, or extracorporeal membrane oxygenation; or subjects who are not expected to survive the current illness
- Underlying immune deficiency, (e.g., from confirmed human immunodeficiency virus infection or use of an immunosuppressive medication except immunoglobulin A deficiency)
- Receipt of (within 12 months before Screening) or on a waiting list for a bone marrow, stem cell, or solid organ transplant, or who received radiation or chemotherapy (within 12 months before screening)
- Receiving chronic oxygen therapy at home before admission
- Receiving an investigational or approved medication that is intended to prevent or treat RSV infection within 30 days or 5 half-lives (whichever is longer) before the first dose of study drug, and/or is currently enrolled in a clinical trial of such a medication. RSV-specific monoclonal antibodies are not prohibited in Part 1.
