Question · Q4 2025
Courtney Breen asked about the flu mRNA-1010 RTF, specifically the percentage of patients 65 or older in the efficacy study. She also inquired about the INT program's path to approval, any feedback on the clinical trial design that provided recommendations not followed, whether Merck or Moderna will file the BLA, and if CBER will be the assessing FDA group.
Answer
Stephen Hoge, President, clarified that the Phase III flu efficacy study had over 50% of its 41,000 participants over age 65, with strong, consistent superior efficacy. For INT, he confirmed robust and productive engagement with FDA and global regulators, with CBER at FDA involved. Merck is the sponsor for the Phase III study and will submit the BLA.
