Prepared Remarks:

Operator

Good morning and good afternoon, and welcome to the Novartis Q2 2023 results release conference call and live webcast. Please note that during the presentation, all participants will be in a listen-only mode, and the conference is being recorded. [Operator instructions] Please limit yourself to one question and return to the queue for any follow-ups. A recording of the conference call, including the Q&A session, will be available on our website shortly after the call ends.

With that, I would like to hand over to Mr. Samir Shah, global head of investor relations. Please go ahead, sir.

Samir Shah -- Global Head of Investor Relations

Thank you very much, Sharon, and good morning and good afternoon, everybody. I want to begin by thanking you for participating in our webcast and investor call again. Before we actually start, I'm going to read the safe harbor statement. The information presented today contains forward-looking statements that involve known and unknown risks, uncertainties, and other factors.

These may cause actual results to be materially different from any future results, performance, or achievements expressed or implied by such statements. For a description of some of these factors, please refer to the company's Form 20-F and its most recent quarterly results on Form 6-K that respectively were filed with and furnished to the U.S. Securities and Exchange Commission. Just a couple of housekeeping points, as per usual, we'll have one question per analyst when we go to the Q&A session, and you'll have time to go back again and ask a second question.

And the other point is that we aim to finish today at quarter past the hour. So, it's 9:15 East Coast time and 15:15 European time. And with that, I'll hand it off to Vas.

Vas Narasimhan -- Chief Executive Officer

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 up 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 we'll 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.

We're 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 at-risk launch on a product of Entresto size in at least 15 years. So, we'll continue to fully defend our IP, citizen 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 that 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 refreshed strategy of focus in five 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, HFrEF indication, but as well as continued use in the HFrEF indication. And importantly, our pediatric approval in the E.U. 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 our 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 healthcare systems continue to stabilize.

Now, when you outlook to the second half, we expect important pipeline milestones with hidradenitis already approved in the E.U. In the U.S., we expect to get approvals of both HS and our 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 autoinjector was also -- we also received approval for. From an LCM standpoint, three 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 a 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 three 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 showed that the medicine has consistent benefit regardless of patient status or combination therapy. The medicine is included in the NCCN guidelines as 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, built on that differentiated profile, allowing us to demonstrate the potential benefits of Kisqali in a broad population of Stage 2 and Stage 3 early breast cancer patients. As a reminder, we had very consistent results across IDFS, RFS, distant disease free survival, and OS. 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. The 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 a 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 updated analysis for IDFS and OS is expected in the second half of 2023.

We expect filings in the E.U. in Q3 and U.S. in Q4, as the FDA would 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 studies 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 have 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 the rolling four week. 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 in 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 our supply is no longer constraining our ability to grow this brand. In Quarter 2, we saw Q2 sales of 240 million. Millburn was approved for the U.S., and Zaragoza was approved for the E.U. 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-taxing data presentation, and we expect filing in the second half. In addition, the PSMA edition 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.

Moving to Leqvio, the launch continues to progress steadily as we've outlooked, and we continue to gain broader and broader utilization and depth among cardiovascular providers in the United States. Sales reached 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 among 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 up 35%. And we've had 16% increase of monthly prescribers on the brand, as well as a 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's data sets to enable it to be used in earlier lines. The ASC4FIRST first-line registrational study has completed enrollment, and we expect the readout and filing in the early part of next year. And we also continue to do additional studies to further profile Scemblix 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 the Iptacopan, where, you're aware, we filed in both PNH, both in the U.S. and the E.U.

We used a priority review voucher as well in the U.S. We also are on track to read out the APPLAUSE-IgAN phase 3 study in the Quarter 4, as well as the APPEAR-C3G data readout as well in Q4 of 2023. And turning to the next slide, when you look ahead now to the potential readouts that we have -- expected readouts we have in the 2024, 2025 timeframe, 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. At OAV-101, gene therapy for SMA in older patients in the 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 two 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 2 and could provide near-term launches 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 has a platform importantly, which enables the siRNAs to be directed using a lipid technology to 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 for cystinosis, really debilitating disease without great therapies currently, as well as a mid-stage radioligand therapy targeting FAPI 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 and Lomb for an upfront of 1.75 billion, as well as a total consideration depending on sales milestones of 2.5 billion.

And we also recently terminated our option agreement for our ociperlimab with BeiGene. So, with that, let me hand it over to Harry. Harry?

Harry Kirsch -- Chief Financial Officer

Yeah, thank you very much, Vas. Good morning and good afternoon, everyone. I'm now going to walk you through some of the financials for the second quarter and the first half. And as always, my comments refer to growth rates and constant currencies, unless otherwise noted.

As you would see from the numbers, it has been a very strong first half of the year. On Slide 19, we detailed the strength of top- and bottom-line performance during Quarter 2 and Half 1. It's really a pleasure to present results like these, which are strong across the board. Overall, we have continued the robust top- and bottom-line growth that we saw at the beginning of the year.

In Quarter 2, sales grew 9%, with broad-based performance across our key therapeutic areas and focused geographies. Core operating income increased by 17%, driven mainly by higher sales. Core EPS grew 25% to $1.83, faster than core operating income, also supported by our 15 billion share buyback program, which we just finished in June. Turning to the first half, sales grew 8%; core operating income, 16%, with strong core EPS growth also of 25% to $3.54.

Free cash flow grew 23% to 6 billion. In summary, a very strong first half of the year as our efforts to focus and streamline the business continue to pay off. On the next slide, Slide 20, I want to go into a bit more detail about performance of innovative medicines in Sandoz. For Quarter 2, innovative medicine sales grew 9%, which drove an increase in innovative medicine's core operating income of 20%.

Core margin improved 340 basis points versus prior year for the quarter, reaching 39% in Quarter 2 for innovative medicines. Sandoz net sales grew 8% for the quarter, mainly driven by Europe and the biosimilar business. Core operating income was up 6% with the core margin up 18% for the quarter. As we move toward the anticipation of the spin-off of Sandoz, we have also provided figures for Novartis, excluding Sandoz, in the bottom row here.

And you see, the Novartis, excluding Sandoz, grew 9% top line and 19% in the bottom line for the quarter. Of course, these numbers are very close to innovative medicines' numbers. And there was also a 300 basis-point growth in the core margin, which reached 37.7%, meaning, we are well on track for 40% midterm margin target. Next slide, please.

I would like to remind everyone about our capital allocation priorities. As a company, we have, of course, substantial cash generation, which we aim to distribute across both our priorities of investing in the business and returning capital to our shareholders. In terms of investing in the business, we have one of the largest R&D budgets in the industry and have spent $43 billion on R&D from 2018 to 2022. Over the same period, we spent about 30 billion on bolt-on M&A opportunities.

In terms of returning capital to shareholders, we have a strong and growing annual dividend in Swiss francs per share and have undertaken regular share buybacks at a reasonable level. Please note that the annual dividend will not be rebased post the Sandoz spin, and Sandoz will also pay its own dividend, essentially providing further uplifts of dividends for our investors. With respect to share buybacks, we have today announced a continuation of our previously completed share buyback program in June with a new up to 15 billion share buyback, which we expect to complete approximately by the end of 2025. Obviously, given our strong cash flows and expected top- and bottom-line continued growth, we continue to have the flexibility to do both share buybacks and bolt-on M&A and BD&L deals.

Now, to Slide 22, please. The continued strong performance so far and confidence in our future growth allows us once again to raise both top- and bottom-line guidance for the full year of 2023. So, for innovative medicines and Novartis, excluding Sandoz, we now expect sales to grow high single digit and core operating income to grow low double digits to mid teens. For Novartis, including Sandoz, which is the group guidance, and assuming that Sandoz would remain within the group for the entire 2023, we now expect sales to grow high single digits and core operating income to grow low double digits.

Our key assumptions are that no U.S. Entresto generic launches happen at risk in 2023 and also that no Sandostatin LAR generics enter in the U.S. in 2023. On the next slide and turning to Sandoz, Sandoz guidance is maintained for 2023.

This guidance is obviously very conservative given the first half delivery, but it's also ahead of a spin-off, and there are clearly upside potentials to that guidance. On the next slide, please. On the assumption that Sandoz becomes an independent company, it will do so clearly from a position of strength. First and foremost, we have built a strong leadership team around Richard with decades of generic industry experience.

Second, the company has a strong pipeline with small molecule generics and biosimilars. Clearly, the sales execution has improved significantly, and Novartis has increased investments to ensure Sandoz has strong future biosimilar capabilities, including a state-of-the-art, new biologics manufacturing site. These strengths will allow Sandoz to execute on its six strategic levers that you see on the right side. I won't go into all the details here, but you have seen Richard and his team having outlined in detail for you all of these priorities during the most recent capital market day and IR roadshows.

On the next page, I just want to turn to the numbers for Sandoz on the next slide. You can see that the business has performed well with respect to sales growth for the last few quarters. Looking specifically at Quarter 2 performance, sales were strong, driven by Europe and biosimilars, and the U.S. has stabilized quarter on quarter.

As expected, stand-up costs mean that the growth rates for core operating income are lower than for the top line. Importantly, for the midterm, we expect solid mid single-digit sales growth and core EBITDA margins to be in the mid-20s. And as a reminder, the first dividend will already be paid in 2024 for the full year 2023 performance. Now, turning to my final slide.

The planned spinoff is well on track. Many of you have attended the Sandoz capital market days and shareholder roadshows. If you have not been able to participate, there will be further opportunities to do so after the extraordinary general meeting. The EGM will take place on September 15, and you will receive the necessary materials, which include the shareholder brochure and listing prospectors as well in advance.

If you and the majority of the shareholders approve the spinoff, we will also be doing post-EGM roadshows in the second half of September, just in time before the expected spinoff in early Q4. And with that, I hand it back to Vas.

Vas Narasimhan -- Chief Executive Officer

Thank you, Harry. So, moving to Slide 28. So, you can see in the quarter that we demonstrated strong business momentum as we are really now well on our way to becoming a truly focused innovative medicines company, very strong Half 1 sales growth, robust margin expansion, and that broad-based performance was across TAs and geographies. We remain very confident in our near and midterm growth profile, including our pipeline, Kisqali, Pluvicto, Iptacopan, as well as the continued performance of our other launch brands such as Kesimpta and Leqvio.

We're raising our 2023 full year guidance, we are initiating based on our confidence in our outlook and in our company at $15 billion share buyback, and we're on track for the Sandoz spinoff in early Q4 2023. So, with that, we can open the line for questions. One question per analyst, please. Sharon?

Questions & Answers:

Operator

[Operator instructions] We will now go to your first question. And the question comes from the line of Richard Vosser from JPMorgan. Please go ahead.

Richard Vosser -- JPMorgan Chase and Company -- Analyst

Hi, thanks for taking my question. A question on Entresto, please. Could you talk about your discussions with the FDA around the citizen petition, around the form of the product, and whether any of the generics meet these requirements, and when we could expect an update around those discussions with the FDA? Thanks very much.

Vas Narasimhan -- Chief Executive Officer

Yeah, thanks, Richard. So, with citizen petitions, we, of course, file them and then there isn't a formal process. So, we're really now awaiting FDA's decision, and there is no timeline necessarily for FDA's decisions around citizen petitions. There are two relevant citizen petitions.

One is on the nature of any potential generic. And our view is that a generic must be an exact match to Entresto, which was an important consideration in the number of generics that might be able to be ultimately approved by the agency, and the second, with respect to labeling and how the label needs to reflect our dosing titration, as well as our overall indication statement for the medicine. So, we'll await that. Typically, the agency will rule on citizen petitions prior to taking an action on any of the generics.

And as we noted earlier that as of right now, there are no approved or pending approvals of generics to our knowledge. Thank you, Richard. Next question, please.

Operator

Thank you. Your next question comes from the line of Jo Walton, Credit Suisse. Please go ahead.

Jo Walton -- Credit Suisse -- Analyst

Hello, can you hear me?

Vas Narasimhan -- Chief Executive Officer

Yes, go ahead, Jo.

Jo Walton -- Credit Suisse -- Analyst

I wonder if you could just tell us a little bit more about Leqvio. You were very confident that there would be an inflection in the second half of the year. You do have a broader label. Could you just tell us a little bit more about say full repositioning levels of reordering, you know, how many doctors have really moved across from having tried it once to saying this is awesome and kept going, and a little bit more, perhaps, about the European rollout.

Thank you.

Vas Narasimhan -- Chief Executive Officer

Yeah, thanks, Jo. You know, with Leqvio, what we see right now is a continued expansion in the number of facilities that are ordering and the number of physicians that are ordering. On the positive side, what we see is once a physician gets beyond a certain number of patients on the medicine, roughly four or five, then they really expand their practice, and they actually can drive quite a bit of depth. But then we have a group of physicians who are still at the one to two dose -- one to two patient level.

And a big part of our efforts right now are to drive greater depth among those prescribers because we find once there's enough scale and a practice of understanding how to operate in Part B that -- then, of course, physicians find the value proposition very compelling. In terms of coverage, we have very good coverage. We were well beyond what the PCSK9 monoclonal has achieved. We're at over 75% coverage at label.

And so, we feel very good about the coverage. So, this is really more about just going step by step, practice by practice, and getting them comfortable with the buy-and-bill process with Part B and all of the details therein. I think we'll continue on a steady trajectory through the second half of the year. Difficult to predict when exactly an inflection will occur, but we know well from our past cardiovascular launches, whether it was Diovan or Lotrel or Entresto, that these things take time.

But once we reach a certain level of scale, that then the launch really takes off, and that's what we continue to expect for Leqvio. Overseas, we see good performance in the European markets where we primarily launched in the private markets, so very good. And now, in the U.K., we are starting to see an uptick as the U.K. has rolled out some additional programs for physicians to create incentives to get their patients to goal for cholesterol.

So, I think that's really helping the rollout in the U.K. And then, looking forward, we continue to work toward approvals in China and Japan, which should further help Leqvio's growth trajectory in the medium to long term. Thanks for the question, Joe. Next question, operator.

Operator

Thank you. Your next question comes from the line of Emmanuel Papadakis from DB. Please go ahead.

Emmanuel Papadakis -- Deutsche Bank -- Analyst

Thank you for taking the question. Maybe I could take one on Pluvicto. So, just a few thoughts ahead of the PSMAfore details, which you obviously headlined PFS for quite some time ago in December, but you've yet to present. So, ahead of seeing the details, any thoughts on whether that will directionally look similar to vision? Thoughts about how our OS trends may also match and mirror that data set? And then, just a word, if we get on the supply situation, the cadence of sales for H2 and beyond.

You reiterated the over 1 billion number, but how could PSMAfore reflect that addressable opportunity next year? And if it's not pushing my luck, we've got a competitor readout splash also due by the end of the year. Just love to hear your latest thoughts in terms of differentiation, mechanistic, or logistic. Thank you.

Vas Narasimhan -- Chief Executive Officer

Yeah, thanks, Emmanuel. So, on Pluvicto, we continue to see very strong demand for this medicine, and we're really now getting back out to actively promoting and generating demand as we've gotten our supply situation stabilized and beginning to expand. So, on the vision population, we continue to see very robust growth, and we would expect, as I outlined, over $1 billion of sales. Now, how much larger that gets is really dependent on how fast we can bring facilities online and work through the logistics of getting these centers scaled and up and running.

Now, in terms of PSMAfore, we outlined that we had a clinically meaningful, statistically significant readout in RPFS. We're now awaiting the maturation of OS. I think as everyone knows, the FDA is now requiring companies to have not just no detriment on OS on these readouts, but mature-enough data set, as well in terms of the information fraction available. So, that's why it's taking us a bit more time to get to that.

But that will then enable us to provide the full data set later this year, both for RPFS and OS. And what I can say is we found the RPFS data to be clinically meaningful and, we think, important for clinical practice. So, what will that mean for demand? You know, depending on how you, when you speak to physicians, at least the physicians I've spoken with personally, as well as heard through others, a potential tripling, I mean, on the order of that level, of the potential demand for the product in a given center. It's too early to say exactly the trajectory of that and really depend on the timing of us getting the approval, which would enable then the reimbursement.

But it would be a substantial, we believe, expansion of the potential for Pluvicto in the marketplace, which puts, I think, really the importance of us getting our Indianapolis site fully approved and up and running later this year. That would enable us between Millburn, our site in Italy, Ivrea, and Indianapolis to fully meet the demand. In terms of the competitor, our understanding of that competitor readout is similar to PSMAfore. And I think, really, this is a market that you need outstanding supply chain logistics, commercial scale, and the ability to consistently deliver for customers, not only in the U.S.

and around the world. And really, we believe our key differentiators will be experience with Pluvicto, as well as the supply chain that we've built that enables confidence in the supply. I would note as well, we're continuing to pursue Pluvicto as well in other markets. So, Japan, eventually other markets in Asia, as well as continued expansion in Europe.

So, it's very exciting. It's an exciting medicine. I would take a moment as well to say we also invest on our broader pipeline within RLT. Not only do we look at expansion of Pluvicto into the pre-metastatic setting, as well as biochemical recurrence delayed castration, but as well, we have our Lutathera programs, looking at other types of cancers.

We're advancing our FAPI program, which we recently acquired, as I mentioned, from Clovis in a range of different tumors. We have our bombazine program, which we're looking at a number of mid-stage studies as well. So, a lot of things happening in the RLT space, and we continue to believe, given the infrastructure we're building and the potential to have compelling efficacy and a very good safety profile so far, with a limited number of administrations, is very compelling to both patients, providers, and hospital systems. 

Emmanuel Papadakis -- Deutsche Bank -- Analyst

Thank you.

Vas Narasimhan -- Chief Executive Officer

Thank you, Emmanuel. Next question, operator.

Operator

Thank you. Your next question comes from the line of Emily Field from Barclays. Please go ahead.

Emily Field -- Barclays -- Analyst

Hi. Thanks for taking my question. I just wanted to ask a question about MBL-949. I know it was updated this quarter that that was discontinued for efficacy.

But just, you know, how you're thinking about the commitment to sort of the broader cardiometabolic space inclusive of obesity, given that you have a pretty substantial cardiovascular infrastructure from the commercial side? Is that, you know, an area for potentially focused business development? Thank you.

Vas Narasimhan -- Chief Executive Officer

Yeah. Thanks, Emily. So, the MBL ultimately did not have a compelling overall profile. So, we're stopping that program.

We do have earlier-stage efforts looking at novel mechanisms in the preclinical space in obesity and metabolism, but these are very early and I think, you know, still far away from ultimately reaching the commercial marketplace. Our focus is cardiorenal. I mean we continue to have, of course, on top of our efforts with Entresto and Leqvio, we have Pelacarsen. We have our XXB program, which is a novel mechanism looking at hypertension and heart failure; a range of programs in the clinic now in antiarrhythmic agents; as well as we're advancing a broad portfolio of siRNAs to follow up on Leqvio to address cardiovascular risk reduction, we hope with less frequent therapy and hitting multiple different drug targets at the same time.

On the renal side, as I mentioned, building on Iptacopan. We have the proposed acquisition of Chinook, as well as our continued efforts to treat a broad range of renal diseases, where we think there's a lot of unmet need and the opportunity to bring meaningful medicines forward. So, that's where we will be focusing on in the years ahead. Next question, operator.

 Thank you. Your next question comes from the line of Graham Parry, Bank of America. Please go ahead.

Graham Parry -- Bank of America Merrill Lynch -- Analyst

Great. Thanks for taking my question. It's on Entresto patent litigation again. So, we understand the 938 Delaware MDL litigation that was subject to a trial in October last year is now being settled ahead of ruling.

So, if you could just confirm that's correct, which filers you settled with and whether the filers that were in the 659 ruling two weeks ago for MSN, Macleods, and Hetero a part of that settlement? And then, how is the 938 and 134 crystalline patents being asserted against those filers that were successful in the 659 ruling that we saw a couple of weeks ago? So, overall, I guess, the broader question is, is there still a scenario where generic Entresto doesn't launch until November 2027 or later? Or do you now see that as off the cards and the latest that you could protect this being mid-2025? Thank you.

Vas Narasimhan -- Chief Executive Officer

Yeah. Thanks, Graham. So, you know, the overall Entresto situation is complex in that each one of the generic filers has different scenarios in terms of the patents that they -- we believe they've infringed, and we've asserted against them. They have different approaches, which may or may not enable them to ultimately get approved depending on how FDA rules on citizen petitions.

So, I'm not going to get into all of the details. I can confirm that we did -- as you did note, we did settle the 938 patent with Crystal and the relevant other generics. And so, that matter is closed off from our perspective. But in terms of the rest right now, our focus is on appealing the district court ruling, where we feel that we have strong grounds to ultimately prevail on appeal to continue to assert our remaining patents through the various litigations that we have ongoing to await the citizen petition ruling.

Our forecasting guidance remains unchanged at a mid-2025 forecasting guidance. We, of course, will do everything we can to extend our overall support longer -- overall exclusivity longer for Entresto. And as I mentioned as well, there's no generics currently approved. And in terms of the history here, nobody has filled that launched at risk on a brand of this size in the last 15 years.

So, all of that gives us confidence on the outlook on the brand. Thanks, Graham. Next question, operator.

Thank you. Your next question comes from the line of Michael Leuchten, UBS. Please go ahead. Hello, Michael.

Is your line on mute?

Michael Leuchten -- UBS -- Analyst

Sorry. It's Mike from UBS. Obligatory question for Harry, please. The guidance implies a less of a margin gearing from the top line in the second half.

What opex lines would be heavier as we're heading into the second half that wouldn't allow you to gear the top line as much as we saw in the first half?

Harry Kirsch -- Chief Financial Officer

Yes, Michael, thank you for the question. So, overall, maybe if we talk about Novartis, ex-Sandoz, right, there will be a little bit more inflation coming through on the COGS line as inventory, of course, gets used like through six months, if you will. Not dramatic, but, you know, a little bit there. The other one is we started to get our transformation for growth savings in Quarter 4 last year.

So, that's a bit harder comp. And, of course, one is a bit conservative, maybe also so maybe there's a bit more upside coming. So, overall, I do see that the sales continues to have this very good momentum. And then, maybe a little bit less bottom line leverage, but still a very nice bottom line leverage, right? We have 340 basis-points improvement.

I think one cannot assume that it happens every quarter and every year. So, those are the things. And then, of course, on the group guidance, that has to do with Sandoz in the second half, expecting also a little bit higher COGS line, lower gross margin due to inflation, as well as some stand-up costs. That is then on the Sandoz P&L a bit more, obviously.

Will it be as much as guided? We have to see that. Spin situation is a bit more volatile than normal ongoing business. But overall, I would say, especially for Novartis, ex-Sandoz, continued fantastic top- and bottom-line performance expected, with maybe a little bit less margin leverage than we have seen in the first two quarters.

Vas Narasimhan -- Chief Executive Officer

Thanks, Michael. Thanks, Harry. Next question, operator.

Operator

Thank you. Your next question comes from the line of Tim Anderson from Wolfe Research. Please go ahead.

Tim Anderson -- Wolfe Research -- Analyst

Thank you. Could I just go back to Entresto? So, if generics do, in fact, launch early and at risk, how does Novartis adapt to that reality? I'm guessing you may not have significant additional cost to pull out of the organization, for example, because you're still promoting other drugs in the category. So, maybe you could talk about your cost levers in that worst-case scenario and then also what it would mean toward M&A strategy? Thank you.

Vas Narasimhan -- Chief Executive Officer

Yeah. Thanks, Tim. As we stated, we continue to not expect generics to launch at risk given the risk of trouble damages in such a brand of this size, as well as the strength of we believe our case on appeal. That said, you know, we feel confident that in the midterm, we'll continue to hit our 4% sales and 40% margin guidance for the company, ex-Sandoz, as Harry outlined.

And that wouldn't require us to take any additional cost out because we had already assumed Entresto would go in mid-2025 as our forecasting assumption. So, our five-year CAGR outlook and 40% margin outlook already assumed that Entresto will be moving out. So, all of our current transformation programs, procurement programs, etc., as they continue to mature, would enable us to still achieve those mid-term goals. Harry, anything you want to add?

Harry Kirsch -- Chief Financial Officer

I think, Tim, you're right, the majority of the marketing and sales is, of course, also on the other growth drivers. And these other growth drivers have significant potential. We talked about a few of them, right? So, I do not see that, you know, there would be a significant adjustment on the cost base because of a bit earlier Entresto LOE. On the other hand, in this scenario, we are fully on defending our IP, and that's the focus here.

And then, of course, driving the full portfolio, including Entresto and the other great growth drivers as we go forward and not have a distraction to the organization after having done quite a significant restructuring already. And by the way, we are ahead of our restructuring cost savings. So, all of that is growing also very well, which you also see reflected in the bottom-line numbers.

Vas Narasimhan -- Chief Executive Officer

Thanks, Harry. Thanks, Tim. Next question, operator.

Thank you. Your next question comes from the line of Mark Purcell from Morgan Stanley. Please go ahead.

Mark Purcell -- Morgan Stanley -- Analyst

Yeah, thank you for taking my question. It's on Pluvicto. I wondered, firstly, if you could help us understand the importance of showing a strong trend on overall survival in the PSMAfore trial, given sort of recent rulings and precedents the FDA has taken a bit of a tougher stance when it comes to showing an OS benefit in prostate cancer specifically. The reason for the question is we've been asked about the relevance of the PFS benefit in patients progressing on an androgen receptor pathway inhibitor being rerandomized on alternative ARPI, as opposed to being moved on to a taxane in the control arm.

And therefore, you'd expect a high crossover rate from the control arm to Pluvicto in this study. So, recognizing, clearly, they've shown -- already shown a strong PFS benefit with the trial powered for a 44% benefit. But how important is it to show the strong OS benefit to gain approval from the regulatory authorities? Thank you.

Vas Narasimhan -- Chief Executive Officer

Yeah. Very good question, Mark. So, right now, our trial is designed in such a way -- and our agreements with FDA is that we would need to show no detriment to OS and a compelling rPFS benefit. As you likely, rightly note, there will be significant crossover in the study because these patients have few alternatives at that point in time and so crossing over to Pluvicto after the results that we announced earlier, of course, will happen.

So, our current expectation is to show no detriment to OS. On an upside case, we would show a positive OS already now. And then, over time, of course, the OS will mature. But with FDA, we have an agreement and understanding that there will be crossover that we'll need to account for in the study analysis.

Thank you. Your next question comes from the line of Kerry Holford from Berenberg. Please go ahead.

Kerry Holford -- Berenberg Capital Markets -- Analyst

Thank you for taking my question. It's on Kesimpta. So, clearly an impressive growth this quarter. But can you talk to your expectations for this product as we head into next year and beyond? In light of the new subcutaneous competition, it looks like need to be coming, I'm referring here to the recent positive data the Roche's subcut formulation of OCREVUS.

So, what is the risk here that you lose share to OCREVUS as a less frequently dosed subcut well-established option when that reaches the market? Thank you.

Vas Narasimhan -- Chief Executive Officer

Yeah. Thanks, Kerry. I think first, we'll have to see the full data set. Because I think as you know, one of the challenges with IV administered of CD20s, whether given in a long infusion or a subcu pump short infusion is do you need to steroid pre-treat and what is the level of reactogenicity and injection site reactions that you're going to see with the medicine.

Overall, our expectation is that the players who are currently compete -- are going to compete with one another for the market for physicians who prefer to provide IV-administered medicines or subcu pump-administered medicines in the Part B setting. And that, you know, where Kesimpta continues to do extremely well is among physicians who prefer to treat their patients with at-home administered monthly medicines and Kesimpta's outstanding efficacy and safety profile. So, we're prepared if, ultimately, there is a move by our competitors to try to move into the at-home subcu administration space. But we feel confident in the Kesimpta profile.

You have to remember, this is a medicine that takes, you know, a minute to give yourself -- a patient to give themselves a month, so 12 minutes a year. You don't have to have any pre-administration, you don't have to deal with pumps and other technologies, which I think in this patient population is greatly, greatly valued. So, we think the overall proposition is clear. We have to be aware of the competition, but we feel confident in the outlook for Kesimpta.

Thank you. Your next question comes from the line of Steve Scala from Cowen. Please go ahead. Your line is open.

Steve Scala -- Cowen and Company -- Analyst

Thank you so much. Also, on Entresto, but regarding the new $15 billion share repurchase. Based on what Novartis is saying, it sounds as though Novartis has every intention of fully completing the new $15 billion share repurchase by year-end 2025, even if, for instance, a generic Entresto were to launch tomorrow, which I guess is within the realm of possibility. Is that correct? Or is the share repurchase telling us that Novartis believes the probability of a generic Entresto launch between now and year-end 2025 is essentially zero? Thank you.

Vas Narasimhan -- Chief Executive Officer

So, Steve, on your first question, it is correct. Our $15 billion share buyback is independent of various business scenarios, including Entresto, but other business scenarios. It's based on a long-term view that we have adequate capital to pursue our internal investments, as well as our external M&A and BD&L. We're confident in the outlook for the company.

It's our growth outlook and, ultimately, where we believe our share price will appreciate, and believe it's prudent to buy back our shares over this period of time and returning capital to shareholders and, also, as we fundamentally believe we're undervalued versus our potential. So, those are the reasons for the share buyback. And we are also confident that, while we can't exclude, as I've mentioned many times on the call today, a generic will launch at risk, we believe we have a compelling case with respect to appealing the district court ruling, a compelling case across a range of other patents that go out to 2027, or in the case of our dosing titration patent to 2036, as well as the various citizens petitions we have with the FDA. So, we maintain as well our guidance for our expectation from a forecasting standpoint that there wouldn't be Entresto generics in the U.S.

before mid-2025.

Thank you. Your next question comes from the line of Seamus Fernandez from Guggenheim Securities. Please go ahead.

Seamus Fernandez -- Guggenheim Partners -- Analyst

Thanks very much. So, my question is a quick one. Just on the BTK, can you potentially update us on if FDA has made any request of your preliminary data or of your ongoing clinical trials just with regard to potential risk of liver injury? You know, the agency is reviewing the overall class more broadly, and this, you know, has been a stated differentiating factor. Just didn't know how long the FDA is requiring or potentially requesting Novartis study the product to kind of disabuse that potential risk.

Thanks so much.

Vas Narasimhan -- Chief Executive Officer

Yeah. Thanks, Seamus. So, consistent with I think they've asked other sponsors, we do have enhanced liver monitoring in our mobile sclerosis programs, and, I have to double-check, but I think also in CSU programs. To date, we have not seen any liver signals have been placed on any kind of clinical hold.

We continue to believe that this is not class specific to the BTK target, but specific to the design of individual molecules in the space. And if you look at, as we've noted, I think, in the past and you've seen our chemical structure is quite different than the chemical structure of the other BTK inhibitors being pursued either in neuroscience or in other indications, which is why we think it has the unique profile that it does from a safety standpoint. So, we're looking forward to the initial efficacy readouts in CSU in the second half of this year, which hopefully will enable us to file in CSU and get a first label in immunology for remibrutinib and then following that up with multiple sclerosis, as well as other immunology indications over time.

Naresh Chouhan -- Intron Health -- Analyst

Hi, there. Thanks for taking my questions. Just one on Hyrimoz, please. Just trying to get a feel for how we should think about the sales trajectory over the next kind of 18 months given the importance for Sandoz.

Should we -- given it's -- the six months of this year, should we expect a fast launch this year? Or will you need to negotiate the formulary position for 2024 before we get a better feel for where this can go? Thank you.

Vas Narasimhan -- Chief Executive Officer

Yeah. Thanks, Naresh. Right now, I think it's early days on the Hyrimoz launch. There have been multiple competitors entering.

Sandoz is also entering. I would expect a slow ramp for this medicine as we continue to get strong positions with payers, as well as get the infrastructure up and running to launch. But over time, we do believe this will be a meaningful growth contributor to Sandoz U.S. and, ultimately, global growth in overall biosimilars business outlook.

Let me hand it over to Harry in case he has anything to add.

Harry Kirsch -- Chief Financial Officer

Thank you. No it's, overall, too early, Naresh, to talk about now peak sales and other things, right? The launch is just starting. And as Vas said, we get on plan formulary positions. And Karen or Ruby on the U.S.

Thank you. Your next question comes from the line of Peter Welford from Jefferies. Please go ahead.

Peter Welford -- Jefferies -- Analyst

 Hi. Thanks for taking my question. It's just in general on returning back to capital allocation, just what would we think about the $15 billion buyback. I mean, last time, you did a buyback of that magnitude was obviously following the Roche share disposal.

Now you're doing another one again based on the underlying cash flows. But I wonder if you could just talk about whether we should read into this anything about further needs or further desire to slim down the portfolio like you did with ophthalmology, and whether or not, you know, there's any divestments that's sort of related to that? And how far you are on sort of the process of that sort of proving down to focus on the core therapeutic areas?

Vas Narasimhan -- Chief Executive Officer

Yeah. Thanks, Peter. I'll cover the focus, and I'll let Harry take on capital allocation. So, we've done a lot.

As you know I mean if you go back five, six years, between the exits of the consumer health business, Alcon, Roche stake, now the proposal on Sandoz, alongside that streaming down to -- streamlining down to five therapeutic areas, exiting areas like liver, as well as diabetes and now front of the eye, really, I think we're in the right place in terms of the therapeutic areas we're in. There may be one-offs that we still need to do in terms of streamlining, but nothing major that we would foresee at this point in time. And really, our goal is, post the Sandoz spin, is to focus on driving the pipeline, driving the strong operational performance you're seeing and hopefully exceeding the 4% sales growth and driving to that 40% company margin as a new Novartis, ex-Sandoz, by 2027. From a capital allocation standpoint, Harry?

Harry Kirsch -- Chief Financial Officer

Yeah. Peter, overall, of course, we do our mid- and long-term liquidity planning, right? So, you could say this is simply a continuation of a, let's say, very responsible capital allocation application. On the other hand, you can be also, in a very pragmatic way, you know, from the Roche stake, we have about 6 billion left. There will be a certain debt push down to Sandoz, and that pays already for the majority of the 15 billion.

On top of that, of course, we have and expect continued very good cash flows. And, of course, in that planning, we always have still flexibility for executing our bolt-on M&A and BD&L strategy over the years. So, all of that is simply a normal continuation of our capital allocation strategy, built on a very strong balance sheet. As you may know, our net debt is just 15 billion.

So, it's below one-time EBITDA. It's a very strong balance sheet there. We have strong cash flows. And from that standpoint I think it's just a logic way to continue share buyback at the same time, of course, a growing dividend in Swiss franc per share for the Novartis, ex-Sandoz.

Not rebasing after the Sandoz spin, and then Sandoz will pay another dividend on top of that. So, I would say it's a logic extension of our capital allocation that provides us a lot of still flexibility on M&A and BD&L. But we focus on bolt-on as always.

Thank you. Your next question comes from the line of Andrew Baum from Citi. Please go ahead.

Andrew Baum -- Citi -- Analyst

Thank you. Question for Vas on how you protect Leqvio from IRA-related price negotiation in the Medicare patients. Now, I'm assuming, given the duration of exposure around for the magnitude of MACE reduction is going to massively exceed that for Repatha and Praluent, and you're probably going to get a significant fatal MI benefit as well. If those assumptions are correct, how protective you think it will be when the clock strikes after nine years and you have price negotiation? I'm asking partly because you just opened the Victorian-1P trial, which is another large and expensive trial.

So, that's the first part. And the second part is just for Victorian-1P, what percentage of that trial population in the real world, do you think, is outside the Medicare patient population and therefore immune from the impact of price negotiation?

Vas Narasimhan -- Chief Executive Officer

Yeah. Thanks, Andrew. All very good questions. So, our overall strategy with Leqvio, and I say this with two important caveats, we don't know yet exactly how, as you know, CMS is going to be looking at data sets and how they're going to ultimately transact the price negotiations.

We'll understand more, I think, over the coming years. And then, second, we continue to advocate for moving the nine to 13 as an industry and as a company. And also more specifically until that big move happens also advocating that siRNAs and related therapeutics were never intended to be part of the nine-year portion of this ruling. And there is bipartisan legislation that's been tabled, at least in the Senate, trying to correct that -- those issues.

So, two elements of our story. One, as you rightly point out, is data. We believe that V-2P, given the longer follow-up that we'll have versus the PCSK9 monoclonal antibodies, so we can hopefully show a very compelling cardiovascular risk reduction. Theoretically, that risk reduction could be in the 25% to 30% when you look at the model outcomes, which we think would be very compelling and hopefully deserving of a price premium if and when the negotiations then happen.

V-1P would give us another data leg. Now, it's important to note, we don't need V-1P anymore from labeling standpoint because we've already received the label from FDA without any limitations on -- in the label referring to the lack of outcomes data. So, we actually have a very optimized label. Nonetheless, we think generating that data will be compelling.

I don't have the exact figures, but I would say a vast majority of those patients would be primary prevention patients would be below 65 years of age. And so, that also is another leg. Second, we are advancing combination programs of combination siRNAs. So, two -- one is working toward combinations with HMG-CoA reductase but also looking at are there ways to extend as well the intervals at which Leqvio would ultimately have to be given.

So, all strategies, we're looking at as well to protect Leqvio in long run in this situation. So, I think a lot will be seen in the coming years, but clearly something that's high in our minds to make sure we can protect this medicine. As a reminder, its patents go up to between 2036 and 2038, so we would have a long runway if we can navigate IRA. Next question, operator.

Thank you. Your next question comes from the line of Simon Baker from Redburn. Please go ahead.

Simon Baker -- Redburn -- Analyst

Thank you for taking my question. And coincidentally, it's also on [Technical difficulty] again to Jo's question and also touching on Andrew's. Given the strong progress you're making on the number of facilities, the number on board for buy-and-bill, I just wonder if you could give us a bit more detail on those [Technical difficulty] facilities and with prescribers. What's driving in that physician inertia from getting people from putting a few people on to four, five plus? Is it related to the profile of the product? Are people waiting for more data? Is it buy-and-bill? Is it Part B? If you could just give us a little bit more color on what's stopping that move.

Was it simply there is a lag time between people coming on board and becoming multiple prescribers? Thanks so much.

Vas Narasimhan -- Chief Executive Officer

Yeah. Thanks, Simon. I think the biggest, you know, topic is just helping physician offices, inclusive of the physician, to understand how to navigate the Part B buy-and-bill system. I mean we still have a surprising number of physicians who ultimately file for reimbursement for Leqvio on the first two doses under the pharmacy benefit.

And under the pharmacy benefit, they will either get rejected or go through a lot of hassle, and then that ultimately frustrates them. So, we're really focused now on educating physicians as best we can and physician offices that you need to set up a separate pathway, buy-and-bill is a different approach. And once they actually get that experience of both having the patient get on the medicine, ultimately, there is no co-pay for many of these patients depending on the insurance that they're in. There's net cost recovery for the physician.

So, many benefits. And then when they get through that journey, then they expand very quickly from two patients to eight patients to 10 patients to 12 patients. We're losing physicians because of that initial step of misunderstanding pharmacy versus medical, how to actually procure here under buy-and-bill. I would say, frankly, we underestimated that challenge, but that doesn't change our conviction when we see how -- when physician offices do convert, how large and big they grow.

It gives us the conviction that if we can get through that hurdle of getting enough offices to fully understand that there is a big runway for this project -- product coming out of that. And so that's the work we still need to work through over the coming months.

Thank you. Your next question comes from the line of Eric Le Berrigaud from Stifel. Please go ahead.

Eric Le Berrigaud -- Stifel Financial Corp. -- Analyst

Yes, good afternoon. Thanks for taking the question. Actually, the question is how to reconcile the second in a row raise in the full year guidance, the midterm guidance, because after the second raise in 2023, you will end up '23 by growing probably 8% to 9%, i.e., double the expected range of growth for the four to five coming years. So, how should we think about this? There are basically two scenarios.

One, growth is very much front-end loaded and the end part of the period will show slow growth or you're just very conservative. You're surprised yourself by the strength in the business this year, and you might surprise also by the strength in the business for the next four to five years. Thank you.

Vas Narasimhan -- Chief Executive Officer

Yeah. Thanks for the question. I think it's a very valid point. I mean overall, right now, we want to see, obviously, the continued trajectory on these brands.

Clearly, if Pluvicto, Kisqali in early breast cancer; Iptacopan, Leqvio, inflection; Scemblix, you know, and particularly if Scemblix first line comes, certainly, we have the opportunity to outperform that 4% sales growth, given the outlook that we have. I mean, right now, we maintain that outlook based on what we see today. But I think certainly, our aspiration is to do better. And I think it really comes down to the outlook on those handful of brands.

And if they continue to perform the way they have, there's certainly an opportunity for us to do better than what we've expected last year. Harry, anything to add on your side?

Harry Kirsch -- Chief Financial Officer

I think, of course, the five-year CAGR, right, is harder to lift than a one-year. But obviously, on the other hand, of course, from our financial planning standpoint, the Entresto contributions to the current growth would not be very much at the end of the five years because of our mid-'25 forecast assumption, right, the outlook was to '27. So, it's a technical detail that the Entresto contribution at the end of it would be lower. And that's why we also outlined at the time when we gave the 4% CAGR, if we are able to hold on to Entresto in the U.S.

longer, that this 4% CAGR would get to a 5% CAGR. So, we are in that range at the moment. And as Vas says, if Pluvicto, Kisqali, Kesimpta, Scemblix and -- continue to outperform like this, we certainly see the potential for overperformance.

Rajesh Kumar -- HSBC -- Analyst

 Hi. Good afternoon. If I may -- looking -- just looking at the acquisitions you've done, you've announced today or you announced in the quarter, could you run us through how you're thinking on what type of -- or what stage of assets you would acquire have changed as we have, you know, an uncertainty around IRA and also a lot of your peers are also looking to acquire? So, that part of capital allocation, if you could provide us with a bit more color, that would really help.

Vas Narasimhan -- Chief Executive Officer

Yeah, absolutely. I mean, generally, you see us moving to mid-stage and earlier. And as we've always guided, you know, the bolt-on range or smaller deals with Chinook, as you saw, it was in that $3 billion range, so I think very much in line with what we've guided. We are carefully looking at assets in terms of potential IRA impact and ensuring that we think we have opportunities to either manage the IRA impact or avoid the IRA impact, certainly with conditions like Charcot-Marie-Tooth, cystinosis.

These are areas where you wouldn't be impacted by IRA as best as we currently see those patient populations. Certainly, on Chinook, in terms of those renal assets, again, we believe that given the patient profile, overall, largely manageable with respect to IRA. So, that's certainly on our minds. But I think the biggest thing for us is we want assets that are in our core therapeutic areas or in our core platform technologies that have adequate risk reward, where they're de-risked from the basic science.

But still, there's an upside that we believe we can deliver based on our capabilities. And we don't want to overpay for very large deals where assets are fully valued, and it's difficult for us to find upside Novartis is contributing, and therefore difficult to create value for our shareholders.

All right. Thank you for taking my question. Just one last. There has been a lot of discussion obviously about the Entresto LOE, but there's also possible a couple of smaller products that could face generics over the next few years, I'm thinking Promacta and Tasigna.

So, just wondered if you could update for us your latest thinking on expected first generic launches to those two drugs in various territories. Thank you.

Vas Narasimhan -- Chief Executive Officer

Yes. I mean both with Promacta and Tasigna, there's no change to the previous expectations. We obviously are continuing to prosecute with respect to Promacta, our various patents, and seeing if there's a way we can have longer exclusivity on Promacta.

Presumably, San Antonio Breast Cancer Symposium would be a good forum for that. And given that the hazard ratio on overall survival was there approaching board lines statistical significance and when you look at the event rate in that trial now, is there an opportunity to see a statistically significant OS benefit this year if we sort of -- if you continue to predict event rates in line with what you've seen to date in the trial? Thank you.

Yeah. Thanks, Graham. I think on both of those conferences, those would be our aspirations. Of course, we have to get the data and ultimately, you know, get accepted to the various congresses.

But that's certainly in line with our current aspirations. With respect to the OS benefit, it is certainly possible given that we were at 0.76. I think it really will, of course, depend on the event rate and ultimately what we see. But I think there's at least the possibility that we get to a statistically significant OS benefit.

And then, when we look at the competitor OS benefit, we hope that we can demonstrate something that's compelling on that front to build on our broad benefit that we already saw in the iDFS and Stage 2 and Stage 3 patients. So, thank you all very much for joining the call. I really appreciate it. We continue to plan on delivering strong performance for the second half of the year, executing on the Sandoz spin, getting the share buyback moving and updating you with, hopefully, exciting clinical trial data over the course of the second half.

I really appreciate your interest in the company, and we'll keep you updated as we continue to progress on our journey. Thank you again.
