Great. Thank you, Samir, and thanks, everyone, for joining today's call. With me today, I also have Harry Kirsch, our CFO. So let's move straight to Slide 4. And as you saw in our release earlier today, Novartis delivered strong sales growth, excellent margin expansion, and we were able to raise our full year guidance.
Getting into the numbers, our group sales grew at 9% and core op inc at 17%. IM sales were up 9% and core op inc up 20%, allowing us to drive our IM margin to 39%. And Sandoz sales were up 8% and core op inc up 6%. Harry will go through the guidance in more detail, but as you saw, we raised our full year guidance for both sales and core operating income.
We had a number of innovation milestones as well as other strategic milestones over the course of the quarter. And when we go through those over the course of my slides. In addition, you saw that there was a ruling from the District Court regarding one of our patents for Entresto, our combination patent, where, in the process of appealing that patent and feel our arguments are strong to ultimately prevail on appeal, though that process will take 12 to 18 months. We would note there are currently no generics that are currently approved for Entresto. And also of note, in our assessment of recent history, there hasn't been an at-risk launch on a product of Entresto size in at least 15 years.
So we'll continue to fully defend our IP citizens petitions and other elements of our strategy to enable Entresto to have as long an exclusivity period as we believe it deserves.
Now moving to the next slide. Our Q2 growth was driven by strong performance across our key growth drivers. You can see each of our key brands, Entresto, Kesimpta, Pluvicto, Kisqali, Scemblix, Leqvio, all delivered excellent performance in the quarter. And I think this reflects a combination of our new strategy or refresh strategy of focus in 5 key therapeutic areas, as well as our streamlined organization from our transformation last year. That's delivering outstanding growth in market from a top line standpoint, but also delivering strong performance on the bottom line as well. We're going to take each one of those brands in turn in the subsequent slides.
Now moving to Slide 6. Entresto delivered strong double-digit growth in all geographies. The brand grew 37% on the quarter, and you can see robust growth, both ex-U.S. and U.S. On the U.S. side, our weekly TRx prescriptions continue to grow robustly, 38%. Sales growth, 17% NBRx growth. So really outstanding performance on the U.S. side. Ex-U.S., we had 36% constant currency growth, and that's driven by HFrEF, but as well our performance on hypertension in China and Japan.
We remain confident in the outlook for Entresto's continued growth, both driven by guidelines, its HFrEF indication, but as well as continued use in the HFpEF indication. And importantly, our pediatric approval in the EU confirms that we have regulatory data protection through November of 2026.
Now moving to Slide 7. In Cosentyx, our sales stabilized in Cosentyx in the second quarter, with sales up 1%. When you dive in a little bit deeper into Cosentyx performance, you saw U.S. sales down 12% in constant currency. And this was a situation where volume growth was offset by revenue deductions as we outlooked in Q1. There's also the matter of the base impact we had in the previous year from the revenue deduction true-ups we took in the second half of the year, which weren't accounted in the first half of 2022, leading to a higher base last year.
Ex-U.S. sales were up 18% across -- with growth across all of our core indications. And importantly, in China, we're seeing outperformance versus the market with double-digit growth, as the China health care systems continue to stabilize. Now when you outlook to the second half, we expect important pipeline milestones with hidradenitis already approved in the EU. In the U.S., we expect to get approvals of both HS and R-IV formulation, which would allow us to penetrate the Part B segment with respect to Cosentyx, with rheumatologists who continue to use IV formulations of these medicines.
And the 300-milligram auto-injector was also -- we also received approval for -- from an LCM standpoint, 3 important programs continue to progress on track: giant cell arteritis; PMR; and rotator cuff tendinopathy. We did terminate our lupus nephritis program based on a lack of compelling efficacy.
Now moving to the next slide. Kisqali continued strong momentum globally. And I think this is a testament to its excellent differentiated profile. You had 66% growth across the globe driven both by the U.S. and ex-U.S. markets. Our NBRx share now in the U.S. has climbed to 34% on the 3-month rolling, and we continue to see strong month-to-month growth on our NBRx share. And this is, of course, driven by data you all know well, the consistent efficacy we showed in the metastatic setting across MONALEESA-2, 7 and 3, which show that the medicine has consistent benefit regardless of patient status or combination therapy.
The medicine is included in the NCCN guidelines is the only category 1 treatment for first-line metastatic breast cancer with an aromatase inhibitor.
Now moving to the next slide. Our NATALEE results, which we unveiled at ASCO earlier this summer, build on that differentiated profile, allowing us to demonstrate the potential benefits of Kisqali in a broad population of Stage II and Stage III early breast cancer patients. As a reminder, we had very consistent results across iDFS, RFS, distant disease-free survival and OS. And those consistent results is what give us confidence that we'll be able to achieve a broad label in the early breast cancer setting.
Importantly, as well, we saw a positive OS trend already at this early interim analysis. Now in terms of safety, there were no new safety signals to 400-milligram dose was well tolerated with limited need for dose reductions. AE-related discontinuations were mostly protocol mandated due to lab findings. The most frequent AEs were neutropenia and were liver related. And we had low rates of grade 3 symptomatic AEs, particularly with respect to GI-related symptoms.
Now moving to Slide 10. The next steps for Kisqali will be continued momentum in the metastatic breast cancer setting, where you see strong performance across our key geographies. And we want to continue to drive that momentum as we believe Kisqali is becoming the standard of care in the metastatic space. NATALEE update and analysis for iDFS and OS is expected in the second half of 2023.
We expect filings in the EU in Q3, and U.S. in Q4 at the FDA, we like a greater information fraction on the OS analysis to allow us to get to the filing in Q4 of this year. And we're pursuing a broad label reflecting the intention to treat population studied in NATALEE. So collectively, we believe that NATALEE has enabled Kisqali to have the potential to more than double the number of patients who could benefit from a treatment with a CDK4/6 in the early breast cancer setting.
Now moving to Slide 11. Kesimpta also had an outstanding quarter and continues its strong trajectory, doubling sales versus prior year. Sales were up 105% U.S. NBRx, you can see here, trending very well on a rolling 4 weeks. The TRx in the U.S. was up 80% and NBRx was up 43%. Our B-cell NBRx share is currently 54% of the market, and that, I think, will be a key driver going forward as the B-cell therapies continue to gain a larger and larger share of the MS market.
In Europe as well, now we're seeing strong launch momentum with 24,000 patients treated. And we're confident in the continued growth of this brand, as I mentioned, both with the expansion of B-cell therapies, but also with the compelling profile versus older therapies as well as some competing overall in the B-cell class.
Now moving to Slide 12. Pluvicto continued its strong performance. And importantly, we are at a situation where supply is no longer constraining our ability to grow this brand. In quarter 2, we saw Q2 sales of $240 million. Millburn and -- was approved for the U.S. and Zaragoza was approved for the EU as sites for commercial supply of Pluvicto. And we are ramping up now additional lines in Millburn rapidly. This has allowed us to start adding new patients as well as adding new centers where we have goal to add over 100 new centers over the coming months to enable continued treatment for patients with prostate cancer with Pluvicto. And we have progressed as well our ex-U.S. reimbursement discussions.
Upcoming milestones for Pluvicto will include the PSMAfore pre-taxane data presentation, and we expect a filing in the second half. In addition, the PSMA addition study is progressing on track as well. And we also expect submission and approval of our new Indianapolis site to further increase supply of Pluvicto. So we would expect a continued strong performance in this brand, and we continue to outlook at Pluvicto to exceed $1 billion in sales this year.
And moving to Leqvio. The launch continues to progress steadily as we've outlooked, and we continue to gain broader and broader utilization and adapt amongst cardiovascular providers in the United States. Sales reach $78 million globally. We now have 2,600 facilities that have ordered Leqvio, which is a solid increase versus quarter 1. We are expanding buy-and-bill as the primary mode of acquisition of Leqvio consistently now over time.
And one of our key areas of focus is to drive greater depth amongst early adopters of Leqvio. In general, we find that once physicians reach a certain comfort level with the medicine along with their office staff, then we can reach a significant number or proportion of patients in a given office or clinic, ultimately receiving Leqvio to lower elevated cholesterol.
We've demonstrated already, as you are aware, consistent safety profile for this medicine. But importantly, in the last few weeks, we've also achieved a label expansion in the U.S., which expands Leqvio to patients with primary hyperlipidemia and that, in effect, allows us to move into the primary prevention setting. Less restrictive language for use for statin therapy, meaning that patients do not have to be on a maximally tolerated statin to initiate Leqvio, as well as the removal of several adverse reactions from the safety section. So this will give us an additional catalyst to help us continue to drive broader Leqvio adoption in the U.S. and around the world.
Now looking at Scemblix sales. Scemblix sales were strong in the quarter. This brand continues to outperform our internal expectations. Sales reached $106 million in the quarter. This is driven by our new patient share in the third-line setting, where we've reached now 35%, and we've had a 16% increase of monthly prescribers on the brand, as well as the global rollout of the medicine in Germany and Japan.
I think one of the compelling things of this therapy are excellent efficacy, but also an outstanding safety profile, which clinicians and patients appreciate. And we continue to work to advance Scemblix data set to enable it to be used in earlier lines. The ASC4FIRST first-line registrational study has completed enrollment, and we expect readout and filing in the early part of next year. And we also continue to do additional studies to further profile sublet in the second-line setting as well as in combinations with second-generation TKIs.
Then moving to Slide 15 and turning to our pipeline. A couple of notes here. Our key 2023 readouts are on track. That includes the Kisqali data, which I've already mentioned; the Pluvicto updated analysis, which I've also mentioned; as well as iptacopan, where you're aware, we've filed in both -- PNH both in the U.S. and the EU. We used of priority review voucher as well in the U.S. We also are on track to read out the APPLAUSE-IgAN Phase III study in quarter 4 as well as the APPEAR-C3G data readout as well in Q4 of 2023.
Now turning to the next slide. When you look ahead now to the potential readout that we have -- expected readouts we have in the 2024, 2025 time frame, these also are on track. Remibrutinib will have its primary analysis in CSU, chronic spontaneous urticaria, in the second half of this year, with the final 52-week readout required for regulatory submission in the U.S. in 2024. I've already covered Scemblix and Pluvicto.
Our OAV-101 gene therapy for SMA in older patients with an intrathecal administration is on track now for a readout in 2024. And pelacarsen, ianalumab and additional indications for iptacopan also all are on track, which really gives us a broad array of new medicines to enable us to drive growth in the second half of this decade and into the 2030s.
Moving to the next slide and just to provide an update on some of our external BD&L related efforts. We've done a number of recent deals to bolster our pipeline as well as strengthen our technology platform. We have a proposed acquisition of Chinook Therapeutics, which is currently awaiting regulatory approvals. This would bring into the portfolio 2 late-stage assets for the treatment of renal diseases atrasentan and Zigakibart, which is an anti-APRIL antibody. Both have shown strong proteinuria reduction in Phase II and could provide near-term launches for -- in our portfolio.
We also announced earlier this week the acquisition of DTX, which is an siRNA company, that has an asset that we expect to soon enter human clinical trials for Charcot-Marie-Tooth syndrome, but also as a platform importantly, which enables the siRNAs to be directed using a lipid technology to the central nervous system, which hopefully could open up new opportunities to treat a range of diseases with siRNAs.
We also made important acquisitions of the gene therapy from Avrobio on for cystinosis, a really debilitating disease without great therapies currently, as well as a mid-stage radioligand therapy targeting FAP from Clovis Oncology.
We also continue to focus our portfolio. Consistent with our overall company strategy, we announced the proposed divestment of our front of the eye assets to Bausch & Lomb, for an upfront of $1.75 billion as well as a total consideration depending on sales milestones of $2.5 billion. We also recently terminated our option agreement for ociperlimab with BeiGene.
So with that, let me hand it over to Harry. Harry?
