Thank you, Samir and thanks everyone, for joining today's call. If we move to slide four, Novartis delivered a strong first quarter to start the year. We had strong sales growth, robust margin expansion, we hit our key innovation milestones, and we're raising our full year 2023 guidance, which Harry will go through in more detail.
As you saw in this morning's press release, sales were up 8%, core operating income was up 15% in constant currencies. In Innovative Medicines, sales were up 7% and core operating income was up 18%. We achieved a core margin of 38.7% in IM, and Sandoz was up 8% with core operating income up 3%.
I'll go through some of the innovation milestones in the subsequent slides as well as an update on our recent approvals of our Milburn and Zaragoza manufacturing facilities.
Now, moving to slide five, our key 2023 readouts for our upcoming high-value medicines remain on track. You surely saw earlier in the quarter, our Phase 3 NATALEE trial in adjuvant breast cancer testing this medicine in a broad patient population, have met its primary endpoint at its second interim analysis.
