PresentationMy pleasure to kick off the next session. It's Sachin Jain here from European team at Bank of America. My pleasure to be hosting Paul Hudson, CEO of Sanofi, we have 40 minutes. I think, Paul, perhaps some interim commentary and then we'll get into Q&A. So with that, over to you.Paul HudsonCEO & Director So it's been an interesting year for me and for us. And while we've advanced the pipeline quite significantly. The only thing that's really irritating me was the itepekimab readout with 1 positiv ...
