EMA Committee recommends nod of Sanofi, AstraZeneca Beyfortus for prevention of RSV disease in infants
Paris: Sanofi and AstraZeneca have recently announced that the European Medicines Agency's Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion for Beyfortus (nirsevimab) for the prevention of respiratory syncytial virus (RSV) lower respiratory tract disease in newborns and infants during their first RSV season. If approved, Beyfortus would be the first and only single-dose passive immunization for the broad infant population, including those born healthy, at term or preterm, or with specific health conditions. Beyfortus is being developed jointly by Sanofi and AstraZeneca.
The CHMP based its positive opinion on results from the Beyfortus clinical development program, including the Phase 3 MELODY, Phase 2/3 MEDLEY, and Phase 2b trials. In the MELODY and Phase 2b trials, Beyfortus met its primary endpoint of reducing the incidence of medically attended lower respiratory tract infections (LRTI) caused by RSV during the RSV season vs. placebo with a single dose. The safety profile of Beyfortus was similar to placebo. Beyfortus also demonstrated a comparable safety and tolerability profile to palivizumab in the Phase 2/3 MEDLEY trial.
RSV is the most common cause of LRTIs and a leading cause of hospitalization in all infants, with most hospitalizations occurring in infants born healthy and at term.9-13 RSV-related direct medical costs, globally — including hospital, outpatient and follow-up care — were estimated at €4.82 billion in 2017. Currently there is no preventative option available for all infants and treatment is limited to symptomatic relief.
