Emily Field's questions to Sanofi SA (SNY) leadership • Q1 2025
Question
Emily Field from Barclays asked for quantification of the Beyfortus sales phasing, whether there were stocking incentives, and the U.S. immunization penetration rate. She also questioned the scientific rationale for the brivekimig (TNF/OX40-L bispecific) combination in hidradenitis suppurativa (HS).
Answer
Thomas Triomphe (EVP, Chief Business Officer) confirmed there were no stocking incentives for Beyfortus and stated the U.S. RSV prevention coverage rate was 55-60% last season, leaving room for growth. Houman Ashrafian (EVP, Head of R&D) explained the brivekimig rationale, noting that TNF induces OX40-Ligand, creating a biological precedent for synergy. CEO Paul Hudson added that combination therapies can produce synergistic effects beyond their individual components.
