The purpose of this study is to evaluate the efficacy, safety, pharmacokinetics (PK), and antidrug antibody (ADA) response for MEDI8897 in healthy late preterm and term infants who are 35 weeks or greater gestational age and entering their first RSV season.
This pivotal Phase 3 study will determine if MEDI8897 will prevent medically attended RSV-confirmed lower respiratory tract infections (LRTI) in healthy infants entering their first RSV season. The population to be enrolled is healthy late preterm and term infants born 35 weeks 0 days or greater gestational age (GA) who would not be eligible to receive RSV prophylaxis. A total of approximately 3,000 infants will be randomized 2:1 to receive either MEDI8897 or placebo. All subjects will be followed for approximately 510 days after dosing. Enrollment is planned at approximately 350 sites across the USA, Canada, Europe, Asia, and Southern Hemisphere.
