- Clinical Trial Results: Merck's Enflonsia demonstrated safety and efficacy in a phase 3 trial for respiratory syncytial virus (RSV) treatment, particularly in high-risk infants and children under two, indicating its potential for the second RSV season.
- SMART Trial Data: Data from the SMART trial revealed that monoclonal antibody (mAb) serum concentrations in high-risk children and infants treated with Enflonsia were comparable to those in healthy infants from a pivotal trial, underscoring the drug's effectiveness and safety.
- High-Risk Population: Nearly all participants in the SMART trial had chronic lung disease or congenital heart disease, suggesting that Enflonsia could provide essential protection for these vulnerable groups, with a potential need for an additional dose during the second RSV season.
- Researcher Insights: Paolo Manzoni, an investigator for the SMART trial, noted that these new findings highlight Enflonsia's potential to protect high-risk children, emphasizing the drug's significance in RSV treatment.
