MI-CP117 was a Phase 3, randomized, double-blind, placebo-controlled trial designed to determine if motavizumab is more effective than placebo in reducing RSV hospitalization in otherwise healthy Native American infants during their first RSV season.~Participants were randomized in a 2:1 ratio to receive either 15 mg/kg motavizumab or placebo by intramuscular (IM) injection every 30 days during the RSV season for a maximum of 5 injections.~During their first RSV season, participants were evaluated monthly just prior to each injection of study drug for adverse events (AEs) (including medically attended otitis media), with a final post-dosing follow up evaluation at Study Day 150. During Seasons 1, 2, and 3, blood was to be collected prior to the first and last dose of study drug for serum chemistry evaluations, motavizumab serum concentrations, and anti-motavizumab antibodies. Efficacy and safety outcomes were examined through Study Day 150 and wheezing outcomes were evaluated from the time of randomization until the third birthday.
