TL;DR
A study found that nirsevimab is safe and effective in Japanese infants at risk for severe respiratory infections.
Contribution
The study confirms nirsevimab's safety and pharmacokinetic profile in Japanese infants, supporting its use in this population.
Findings
Nirsevimab was well-tolerated with no safety concerns observed in Japanese infants.
Serum concentrations of nirsevimab were consistent with previously established efficacy levels.
Abstract
In Japanese infants aged ≤12 months at risk for severe respiratory syncytial virus-associated lower respiratory tract infections who received two doses of nirsevimab 5–6 months apart, no safety concerns or anti-drug antibodies occurred. Nirsevimab serum concentrations were consistent with those previously demonstrated to be efficacious in healthy preterm and term infants.
