Thank you very much and welcome to our half year briefing. Before I get into the financials, let me just summarize again the leadership announcements we made this morning. As you have seen, Christoph Franz has decided to step down as chairman of the board, and I'm nominated to succeed him as the chairman at the next general assembly in March 2023. At the same time, Thomas Schinecker will take over as CEO, my current role. I'm really pleased how things come together. My colleagues at the corporate executive team and myself, we very much look forward working with Thomas. We are going to prepare for a smooth transition over the coming months. For now, let's get back to business.
Let's get right into the half year results. It's been a solid set of results. We have seen a 5% growth on a group level. A 3% growth for pharma, which is pretty remarkable. You will see this in later slides as we still have a significant erosion due to the biosimilars and due to the entry of biosimilars. If you look at the underlying growth, if you correct for Ronapreve and the biosimilars, actually, the new portfolio is growing in the double digits. This is really a very positive and dynamic evolution on the pharma side. Diagnostics continues with a strong growth momentum. We have seen additional momentum in the first quarter for the COVID testing.
This has decreased in the second quarter and is supposed to decrease further for the remainder of this year. What is good to note is a really good solid growth of the underlying our routine business excluding COVID tests. For the future, I think we are well positioned here. Now, on the product portfolio, I'll come back to that in a moment, but we see not only a very strong continued growth with the newly launched medicines. On top of it, we could launch new medicines in the first half of this year. Let me just highlight Vabysmo here, where we have seen really an extraordinary launch with very good demand from the community for this novel medicine against eye diseases.
Now, if we move forward to the specific numbers again, pharma up 3%, diagnostics 11%, overall 5%. If you look now here on the quarterly development, you can immediately see the impact of COVID-19. While we have still seen a strong growth in the first quarter, you see here a negative development and, as a result, on a group level, we have grown only, I mean, it was only a flat growth, very much as we would have expected. I think that's a really interesting and pretty exciting slide.
If you look at our new pharma products, you can see CHF 1.6 billion growth in just six months, and that is more than compensating for the erosion which we see with Avastin, Herceptin, and Rituxan, which is roughly CHF 1 billion. That is really good to see as the impact of the biosimilars will further slow down over the coming years. You see this also reflected on the right-hand side of this slide where AHR has now a minor part of our overall portfolio. You remember not so many years ago, it accounted for almost half of our total sales. The portfolio has really rejuvenated a lot over a relatively short period of time.
Here, if we look a bit what is happening on a quarterly basis and what is happening with the underlying business both in pharma, I think that is a useful slide. What we did here is on the left-hand side for pharma, we excluded Ronapreve. That had quite some impact, still a positive impact in Q1 and a negative one in Q2. If you look here at the underlying business, you see a positive momentum with 4% sales growth in the second quarter. Even more importantly, of course, if you take out the effect for biosimilars, we are actually in the high single digits for pharma. On the diagnostic side again, here, a huge impact with the declining growth due to COVID-19.
You see actually a little bit of a dip in the base business in the second quarter. There's some temporary impacts due to China where we had lockdowns. We expect that to pick up. We have actually had already a strong start into Q3, so we should see a positive trend for the base business for the remainder of this year. On the financials, Alan will lead you through in much more detail. It's a bit of a special year with a number of special items. You see here core EPS up 11%. So that is also a result of the accretion due to the repurchase of the shares from Novartis.
We had a patent settlement in Japan, which was helping on the core earnings per share. Overall, a very good development both on profit margins and also on the cash flow. I mentioned Vabysmo. That's certainly a highlight in the first half of this year. Off to a very good start. Let me, however, not forget about Lunsumio and Polivy, which has been recently launched. It's now available in Europe for follicular lymphoma as far as Lunsumio is concerned, and for first-line aggressive form of lymphoma for Polivy. That's really good to see and we see a strong initial demand for those medicines as well. Now for the outlook, I've talked about the recent launches in pharma.
There's also a lot happening on the diagnostic side. We had a very successful launch in particular of cobas 5800, our kind of mid-size molecular platform, and the cobas pure. Those two platforms are now supposed to get FDA approval in the U.S. so that we can also enter this important market. There's a number of other platforms and diagnostic tests in the making, and I'm sure Thomas will comment on that in more detail. Outlook, this is a slide we showed you at the beginning of this year and it's still very true. As you have seen, we have confirmed the outlook for the full year. Good growth both with the new products in pharma and the base business in diagnostics.
We do have the drag with biosimilars, and we also expect lower sales for COVID-19. Now, I should say, of course, all of that is based on the assumption that we don't see new and importantly, more dangerous variants of the COVID-19 virus. In case we would be confronted with a new development on that front, that of course, would also have an impact on our sales for the full year. Again, to summarize, group sales stable to low-single-digit growth. As far as EPS is concerned, we expect low- to mid-single-digit growth and Alan will later lead you through all the specific items which influence that picture.
On that basis, we should be able to further increase our dividend in Swiss francs. With this, thank you very much, and I hand over to Bill.
Thanks, Severin. Hi, everybody. Great to have a chance to share our results. We're really excited about what's going on in the pharma division this year. Fasten your seat belts. Here we go. 3% overall growth, which I think we're encouraged. It's solid growth showing that we're really starting to emerge from the biosimilar period. As I'll discuss in a moment, the COVID impact, the pluses and minuses roughly cancel out. I think you can think about this as, you know, a 3% including the effect of biosimilars. Yeah, I think that's back squarely in the black and we intend to stay there. I'll talk about it. You can see Europe's down a bit, Japan's way up.
That's mostly related to sales of Ronapreve, where we were down in Europe. I think without Ronapreve, we would have been +4% in Europe, and in Japan, we would have been at 8% instead of 34%. They roughly wash out and the 3% is pretty close to the actual without pandemic. From a P&L standpoint, the royalties and other operating income was affected by the large settlement that Chugai had on Ultomiris and so that was a driver in there. In terms of cost of sales, COGS and period costs were up about 9%. Volume was up 8%, so it was up a little more because we were slightly lower capacity utilization.
We were basically at 100% for the last two years. We came down a little bit, which frankly I'm glad to see because I don't like running it at 100% capacity. M&D just reflects a little bit of extra spending on launches. The R&D's down a bit because of really high spending, extra high spending in R&D in the first half of last year, including CHF 200 million extra for Ronapreve and AT-527 last year that didn't recur this year. Then the G&A reflects some tax effects and our continued emphasis on savings there. Core operating profit up 8% and we're glad to be bringing in that result. From a product standpoint, I like the shape of this.
You can see if you look at the top eight lines, number eight is actually Vabysmo, so the newest entrant on the list. It's really excellent to see that the top eight lines are basically products we'll have for a while, and really part of our core portfolio. You can see Hemlibra and Ocrevus each contributing more than CHF 800 million on an annual basis of incremental sales, and then accompanied by strong results from Evrysdi, Phesgo, and we'll talk more about some of the others. Then down at the bottom end, what I would point out is you have AHR and Actemra. Actemra was down CHF 200 million, which basically reflects that in Q2 there was very little sales of Actemra for COVID.
Hopefully it'll stay that way, meaning that the hospitalization rates are down and stay down, but that remains to be seen. I think you can see, for example, with Herceptin and MabThera, we're starting to find the bottom. You know, you've got -16%, -21%, and so I think we're looking forward to being in the sort of post-AHR biosimilar era and getting there pretty quickly. In oncology, encouraged to see our two biggest franchises with growth. The HER2 franchise now where Perjeta, Phesgo, and Kadcyla are all kind of outgrowing the losses in Herceptin and so, you know, really an excellent result up about a little over CHF 9 billion annualized, so strong performance in HER2. Tecentriq with good performance.
We'll come back to that. Yeah, you can see we continue to make gains in the part of hematology that's not Rituxan. Coming back to the HER2 franchise. Phesgo, this is really proving this is our subcutaneous version of H+P, and it's proving very attractive when we have countries that are up at like 90% adoption, particularly healthcare systems where infusion capacity is limited, and we think this will be helpful. I mean, obviously it offers patients and healthcare systems a benefit today, but it'll also provide, you know, a more difficult to challenge product from a biosimilar standpoint when we get to that point with Perjeta. I also just wanted to share a study that we started. This is on the right side of the slide.
I think this is a really neat example of what we can do as a real leader in cancer. This is one where it's like the Phesgo use in first-line metastatic HER2-positive breast cancer. This is for patients who are HER2-positive as well as ER-positive. This time, what we're doing is we're running a phase III study to examine the addition of giredestrant to the standard regimen. Giredestrant is our new SERD and so we've already got metastatic first-line and adjuvant studies ongoing for giredestrant. Now this is a third study, and I think signals our confidence in the data we've seen to date.
What's I think especially important about this is in the maintenance setting, this would give patients basically a lower intervention because giredestrant is a pill and Phesgo is the subQ. It's we hope for a more potent but also more patient-friendly solution for these patients. As I mentioned, Tecentriq strong performance. In Q2, we were at 13%, and the first half was 11%. This just reflects getting the washout from the removed indications in TNBC and bladder cancer. That's kind of getting behind us. Really strong uptake in lung cancer in the adjuvant setting in the U.S..
We're now up to 80% testing in the adjuvant setting for PDL1, and then we're at 60% market share in the PDL1 positive patients or in the high PDL1 patients. I think a very strong launch there. We've just been approved in Europe. We're gonna get approval in Japan probably in the fall. By the way, if you look at the growth chart here, what you can see is quite strong growth in the U.S., in Europe, in international, and actually Japan shrunk, and they had a mandatory price cut at the beginning of the year. I think, you know, the 13% growth isn't all we're capable of and we're looking forward to continued strong growth as well as some good readouts coming up.
Hematology, another area where we've been really busy. We now have, as Severin mentioned, the POLARIX regimen's been approved in Europe. It's been filed in the U.S. and will be approved later this year. It's gonna be approved in August in Japan, and we're getting approvals around the world right now. We think this is a potential for, you know, more than CHF 1 billion of additional revenues. We think adoption will be quite rapid because if you're, you know, one of the seven or eight out of 100 patients that gets a cure from this therapy, this means all the world. We look forward to bringing that to patients in every country.
Lunsumio. Severin also mentioned this is the result and this is why we think this will rapidly become standard of care in third line and later follicular lymphoma. As you can see from the waterfall chart, I mean, 60% of patients with a complete response, 80% of patients with a response. It doesn't require hospitalization as some of the other later line therapies do and look for more there. Then I also wanted to mention Glofitamab, which is our other T-cell bispecific. This one in DLBCL, and we presented this data at ASCO. I think what's particularly compelling is we had a 39% complete response rate, which is quite a high rate of complete response, but also these were really durable. This is a fixed duration therapy.
You have a fixed duration of treatment, and then many patients are going for, you know, months, years without relapsing. We think this is a superior alternative to CAR- T. We're filing this, looking forward to launching Glofitamab. I also wanna point out that these initial approvals of Lunsumio and Glofitamab are really just the beginning for these two molecules. These are both monotherapy approvals, but we think that the real key here is gonna be combinations.
Because we're already the leader in hematology, especially in NHL, follicular lymphoma, CLL, we've got a lot of studies teed up, and you can see the list, including three phase, three studies, glofitamab with chemo in relapsed refractory DLBCL, Polivy and Lunsumio in relapsed refractory DLBCL, and then Lunsumio plus lenalidomide in second line follicular. I think we've got a lot of the bases covered here, and we're looking forward to some really great results in the future. Hemlibra is an excellent growth story. You know, it's just the combination of convenient dosing and high efficacy that's really unsurpassed in hemophilia, is just leading to continued adoption in every country.
Again, you can see from the bars, you know, very strong growth in the U.S. and Europe and international, as well as still some growth in Japan. We continue to see more growth ahead for Hemlibra. We always get the question, you know, sort of where's the top? We're not sure where it is, but we sure haven't found it. Again, you know, more approvals coming in. We have the label expansion to include mild to moderate patients soon in Europe, and we've got the infants results in HAVEN 7 coming soon. Immunology, this is mostly affected by Actemra declines, as I mentioned, due to COVID reductions. Xolair's holding up strong at 13%.
With all the talk about new asthma agents, people sometimes forget that Xolair is still the market leader in asthma but also is growing strongly in urticaria. Esbriet , finally, we did lose the patents. There are multiple generics in the market in the U.S. now, and those sales we anticipate will go away rather quickly. Coming to Ocrevus, again, a really nice growth here. You can see we have more than 250,000 patients. It's the number one, number one market share in new and total in the U.S. and number one in new market share in Europe. We have very high level of persistence, which means that with a given level of.
For example, with 35% new market share in the U.S. we can actually get higher than that in total market share because the other therapies lose patients faster and we get a longer persistence. That's an extra great feature. We have now commenced the phase III study for Ocrevus in subcutaneous Ocrevus, and we'll have results in 2023. Not far away from an Ocrevus subQ for patients. We also have the extensive phase III program with high-dose Ocrevus and Fenebrutinib, our BTK inhibitor. Moving on to SMA, Evrysdi, another really strong picture here.
If you look at the bars, you can see there's growth in every country or in every region, and this is really because of the convenient dosing, strong efficacy, and excellent tolerability of Evrysdi. You know, we're seeing a high level of switching from Spinraza. Also there have been rumors about, do patients stay on Evrysdi? Actually, 90% of our patients are staying on Evrysdi, which is pretty remarkable given that there are some very advanced patients, say with type two or type three, that maybe don't get many benefit from any of the therapies. You know, 90% retention is quite strong here. We continue to expand both our label and geographically, so we look forward to continued growth here.
This is the—I think the first slide I've shown in at least in some time with DMD results, and we're excited with our partner Sarepta to have been sharing these things. The phase I-B study called ENDEAVOR, also called Study 103. This was a cohort of 20 patients, and you can see that these 20 patients, the general trend was they had an increase in their functional score, which you know is atypical. You know, at baseline in non-treated patients, you would typically either see in this time period of a year, either stable or down, and our external control was roughly stable versus the increase for the boys who received the treatment.
We now have the four-year data from the initial cohort of the phase I study. This is obviously a very small data set, but it is good to see that these boys are maintaining their functional gains over time and these will be meaningful contributors to the overall data package. The outlook remains here that we will finish our phase III accrual this year. We'll have results next year, and we'll be filing shortly thereafter. But we are still exploring possibilities for accelerated approval, but our base case remains phase III. On to Vabysmo. We're super excited by the momentum here on this launch. We have. It says 70,000 vials, that was at the end of June. Now it's 80,000 vials.
This is important because so we can assume that most of those vials have been administered, and we haven't seen any, you know, unusual safety signals. This is something that doctors are very closely watching because they wanna make sure that when the real-world experience comes in, that there's no surprises. So far, there's no surprises. You know, 80,000 vials in. It's also noteworthy that in June in the U.S., we actually hit a $500 million annual run rate. What I mean by that is if you basically take June sales and multiply by 12, we were slightly over $500 million. And then Japan has come online in May with reimbursement. They've had a really positive uptake and they're really excited about what that means for the future of Vabysmo.
We now have simultaneous approval and reimbursement by NICE in the U.K., which is very unusual. We're launching there, and we'll be launching in many other countries. Look for more on Vabysmo. This is the latest data which shows that in AMD, we have more than 60% of patients, so 59 in one study and 67 in the other study, were able to extend dosing to four months. This is really unprecedented in this space. This is why I think Vabysmo is being so well-received. We have 60%-70% of our patients are switching from Eylea. A smaller number are switching from Lucentis, and then the least number is patients that are naive. Now reimbursements well-established.
80% of U.S. payers are reimbursing or covering and have policies for Vabysmo. We'll have a permanent J-code on October 1st. As I said, I think all indications are this is going to be a very important medicine in the retina space and a very important medicine for Roche. My last slide, just an update on a few things. One thing I wanted to mention is that we did have a negative study with Tecentriq adjuvant RCC. You know, this was an area where I think our expectations were modest, given sort of mixed results from other checkpoint inhibitors in the adjuvant RCC setting. Nevertheless, we were disappointed to see that we didn't have a statistically significant benefit on disease-free survival. That one's coming out.
Meanwhile, we're continuing to final analysis on the adjuvant head and neck study for Tecentriq, and that'll happen in 2023. Otherwise, I think we mentioned that Alecensa, the adjuvant study, is likely now to read out in early 2023. A lot of good progress for the pipeline and for the launches, and really excited to answer your questions later. I'll turn it over to my fantastic colleague, Thomas.
Thank you very much, Bill. I'm also excited to take you through the diagnostics results. Let me start with the first slide. Now with almost CHF 10 billion sales, we had a growth rate of 11% at constant exchange rates. This was driven by a good growth momentum in the base business, but I'll get into that more on a separate slide. In addition, we had CHF 3.1 billion in COVID testing sales. Now, just one thing I would like to point out on this slide is around diabetes care. I've pointed it out in Q1, but also every quarter last year. We did have a one-time positive effect last year in Q1 due to a settlement agreement.
Without this, actually diabetes care would be flat, which shows that it's holding up quite well. Now, just going quickly into the different regions, you see North America growing 34%. This is on one hand due to rapid antigen tests, but also the base business is doing really well in North America. In EMEA you see a decline, and this is driven only due to COVID-19 sales that are going down. Actually, the base business is growing at 6%. In Latin America, you also have COVID-19 testing sales going down. Here, the base business would actually be growing at 16%. In Asia Pacific, it's a mix between rapid antigen sales and also the base business growth.
Now, I promised I would give you a bit more detail on the different parts of our business. First, let me start with Core Lab. There are basically two effects that are impacting growth in Core Lab. One are the China lockdowns. You see that basically on the right-hand side when you look at immunodiagnostics. A big part of our sales in China are actually immunodiagnostic and clinical chemistry sales. If you look at that, we would be growing either close or around double digit in immunochemistry and immunodiagnostics and clinical chemistry. You see the underlying growth is doing really well in the Core Lab. You see another element, which is Custom Biotech. This is a B2B business that we're doing with other companies.
That's not something that's actually going into the market directly from us. The underlying business in Core Lab is doing extremely well in the high single digits. Point of care, this is where we report our rapid antigen test sales, and also point of care molecular, which is our LIAT, both showing very strong growth. Again, if you back out all the COVID-related sales, the base business is doing well with 7%. Molecular, 1%. Here you see that the PCR testing is going down related to COVID-19. You know, people don't have to quarantine themselves anymore. You don't have people, I think, getting tested before they get on flights, which probably would be a good idea because that's probably one of the reasons why we see a lot of infections at the moment.
You know, the underlying business is growing significantly with more than 16% in molecular. I already commented on diabetes care and pathology, fantastic growth with 10%. Now, this is slides in a bit of a different shape that Severin was also showing. You see, that we had flat growth overall in Q2 2022. This is because we had lower COVID sales than in Q2 last year, and the base business was growing 3%. Now, we were talking about effects like the lockdown in China. Now, if we backed that out, the base business would actually be growing at 6% in Q2.
Now, if we look into Q3, you know, we already have a couple of weeks in Q3 and the trends and what we're saying about the COVID business is actually a reality. We see a strong decline of COVID-related sales in Q3. We also see now with the lockdowns easing to a certain degree in China, a strong pickup again in the base business. Really positive to see the strong base business in the first couple of weeks this month. Now, let me take you through the P&L. First, core operating profit is growing in line with sales, so our margins are stable. Cost of sales is increasing faster than sales. This is due to a product mix effect.
We have a lot of rapid antigen sales in the first half year, and these rapid antigen sales have a much lower margin than the rest of our business, and that's why we have higher growth in cost of sales. M&D is growing 3%. Now, if you look at M&S, excluding distribution, it's actually flat. It's all driven by distribution of our rapid antigen tests. Nothing that will stick in our P&L in the future. Research and development with 11% growth, this just shows our commitment to innovation and G&A with 2%, very small numbers here. You can see that, you know, we have a P&L that's very much controlled on the cost side and the investments in the right areas.
Now, very happy with those results, but let me quickly give you a bit more details on some of the product highlights. Let me start with something that will come out very soon, and that's the Elecsys Interferon Gamma Release Assay for SARS-CoV-2. Now, you know, we have launched in the past antibody assays, so we can measure levels of antibodies. So this is the B cell response. We know that over time, antibody levels go down. But there is a second path where our immune system can defend us in case of an infection with SARS-CoV-2, and that's through T cells and T cell memory. Now we can combine these two tests, really understand, you know, which patients will progress to severe disease and how much protection really is.
This is through the antibody test on one hand, but also this T cell test on the other hand. The way this works is we actually have, you know, a tube with 189 SARS-CoV-2 specific antigens. So these are the proteins of the virus. When you add the blood of the patient, you do an incubation step, and you then afterwards measure the release of a cytokine called interferon gamma. With that, we can measure, you know, how strong the immune response is that is triggered by the T cells. Now, I've shown the slides also in Q1, and I think it's becoming also important at the moment because you always have constantly new variants appearing. At the moment, it looks like BA.5 is the one that's becoming the dominant variant.
Through our genotyping assays, we have more than 10 different assays, we can actually measure, you know, which of the genotypes are becoming dominant. It is much faster than doing sequencing. We can do this within hours, where sequencing it will take you more than a week. In times of pandemic, a week is a long time to actually monitor the spread. A lot of things happen. It's important that you know, measure that in a much shorter time period. Monkeypox is another assay that we released very quickly. You know that on the SARS-CoV-2 side, we were the first company to react. We have a team that constantly monitors the development of new viruses, how they are spreading.
With monkeypox, they realized pretty quickly that it was spreading very abnormally in regions of the world that normally don't see monkeypox. Very quickly, our team started to work to develop a number of assays. We've now also supplied these assays, for example, to the WHO so that we can track you know the spread of this virus. Although not as infectious and not as deadly as SARS-CoV-2, you know, experts now do believe and scientists do believe that this virus may also become endemic in the Western world, unfortunately. Now, another virus, but this virus now is a virus that's known to cause cancer, cervical cancer, is the human papillomavirus. Here we have a test on the market for quite some time.
We also have tissue tests that can help diagnose the cancer, but now we actually have a self-sampling solution also available. Why is this important? It's important because approximately 600,000 women get diagnosed with cervical cancer every year, and more than 50% of these women then die, 342,000 to be exact. Now, 90% of these deaths actually happen in LMICs . One of the reasons is that these women are not screened. Culturally, you know, to go to a gynecologist to get this sample taken is sometimes a difficult thing, and we believe that we can increase the access to our tests by also providing self-sampling solutions so that people actually get screened.
Another virus that also causes a cancer, in this case liver cancer, is hepatitis C. There are 58 million people in the world that are chronically infected, and 80% actually unaware. The good thing is there is actually a treatment, a curative treatment available. If we would screen the population, we can then, you know, treat these people, and then we have a, you know, a lot less liver cancer deaths per year. Now, with this test, which is a combination test of the HCV core antigen and the antibodies, we can actually close the diagnostic window by three weeks, can diagnose much earlier, and actually can find these patients. With that, we can support the WHO in the elimination strategy to eliminate liver cancer caused by hepatitis C.
On the system side, we had two launches, and let me start with BenchMark ULTRA PLUS. You saw that we're doing really well in the pathology area, 10% growth. Most of our business is in the advanced staining space, so immunohistochemistry and in situ hybridization. Now this is running on the BenchMark ULTRA. We've now launched the next generation with features like shorter turnaround times, fewer manual interventions, which is critical because there's always staff shortages. We've also launched this together with our menu with more than 200 assays, which is the leading assay menu in the industry. Very excited to continue to drive this forward. With the digital slide scanner, VENTANA DP 600, we now actually have an opportunity to really enter the digital pathology space.
We already had the DP200 slide scanner, but this slide scanner is much more fit for purpose for really the big cancer centers around the world. We have a slide capacity of 240 slides, so 40 times higher than DP200, which we can scan in a matter of four hours. The slide scanner is just the first step. We have our software, the Navify Digital Pathology, which actually manages the workflow. The real intelligence comes through the AI image analysis. We have a number of algorithms already on our digital pathology platform. We're partnering with a number of other companies to increase the suite of different AI algorithms. This really then helps patients to get a better diagnosis, to get a better outcome.
I mean, I can only say for myself, I mean, looking at those slides, I really would want AI to be used because I know that I can trust those results much more than just when someone looks through the microscope. I really excited to see how the digital pathology business is going forward. Now let me just finish with two slides. First, I'll be in the U.S. next week at the AACC, and of course, I would be very happy to welcome as many of you as possible at this event. We'll show a bit more details on our portfolio, and then we'll also be available for Q&A with some of our members of my leadership team. Finally, let me say that we've had a number of launches this year.
We have a number of them to go. Everything is on track and so really excited then also to show you all the progress that we're making in Q3 and Q4, but I can say, you know, we are really seeing now the output. Just recently, I think on Tuesday, we received breakthrough device designation for the blood-based Alzheimer's markers, so really excited to see how the pathology and all the other areas are really progressing in terms of portfolio. With that, thank you very much, and I hand over to Alan to take you through the financials.
Yeah. Thanks, Thomas. My pleasure to wrap it up a little bit and to lead you through a couple of the facts that we have had in the first half of 2022. Let me get right into it. You see the highlights here. I will address them all anyway in my slides so I move forward quickly, and let me give you the overview here. Before I dig really deeply into that, and that's another point I will address in the presentations as well, and you will see it on different slides, is I wanna make a couple of comments about the H2 performance, because we're sure, and let's grab the bull by the horns, that we will get questions on the guidance.
Let me give you a little bit of background for the second half. One element certainly is when you look at our guidance and when you look how we dealt with COVID, that we assume it's just one scenario, and Severin said it's just one scenario, but looks like that we lose COVID sales in H2 compared to H2 2021. As said, it's just an underlying scenario, but the current assumption which influences the guidance. Another one is a fact last year in the second half. We had a base effect on the tax side. We had a significant release of a tax provision, CHF 601 million, which certainly was a major boost to core EPS in the second half of 2021, which is not recurring.
Another point is, I will talk about the Ultomiris in-licensing agreement a couple of times from Chugai. You know it had a positive impact of CHF 765 million. There might be a question, okay, fine, at least this effect should be mirrored in the guidance. That is a clear change to what you had in mind at the beginning of the year. Let me say one element here. We were always uncertain how COVID would play out. Some people tend to forget that we had from Ronapreve in the second half of 2021 a positive impact on the royalty and other operating income line. That effect was CHF 654 million. You see a little bit, there's a balance coming in.
We have Ultomiris in the first half, if you like, and then in the second half, we will have a negative impact from not having the Ronapreve royalty and other operating income. Just to remind you, that came from the U.S.. Everything we delivered to the U.S. and Regeneron reported as sales. We got a royalty income from that, and that's evidently not recurring in the second half of 2022, or is at least uncertain. Then the last point is the full year accretion from the buyback of the Novartis shares, which is a little bit of a moving target, certainly not in the amount of shares, but when it comes to the profit that you divide by the shares. We see that on one element.
The other element is that we think that the debt level and the interest charges that we're gonna get from that are a little bit lower. The current projection is that the accretion effect for the full year will be 5 percentage points when it comes to core EPS. Good. That will come back again, but I wanted to make sure that these effects are not going to be lost, and I will mention them when I come to the respective slides. Let me lead you through the overall package here. I think sales up 5%. I think Thomas and Bill really framed that well. 11% on the Diagnostics side, 3% on the pharma side. I think quite impressive.
You see the core operating profit with a higher dynamic, with 9%. Certainly here, Ultomiris and the in-licensing agreement with Chugai comes into the game and gives us an additional margin on the core operating profit side. The core net income up 7% in constant rates. What you're gonna see is we lose a little bit momentum. This is not taxes. I will come to that. This is really the equity security. So the Roche Venture Fund, you know we're also investing in-house, yeah, into biotech. And as the biotech market came down, we were basically affected in the same way. There is quite some hope that this has bottomed out now, and we see a positive impact already in July, but let's see what happens until year-end. You see really core net income.
You go to core EPS, and you see a 7% growth on core net income. You see 11% on core EPS. Here are two elements. One, certainly the accretion effect. In the first half of the year, 6%. There's certainly a great performance from Chugai kicking in here as well and lifting the core EPS to 11%. IFRS net income, I have a slide on that, so basically mirroring the momentum that we're having there. You see really, which I find remarkable, the cash flow, you know, that we generated in the first half, with CHF 9.8 billion operating free cash flow, which certainly helps us to deliver it. In the first half, as you know, we paid the dividend. We'll talk about that.
You see the free cash flow with CHF 7.1 billion was a nice increase as well. Let's dig into these numbers. First of all, the split here and the bridge when it comes to sales growth. I think Bill and Thomas have done a great job here already to explain that. You see really we get to, on the right-hand side, CHF 32.3 billion in sales. When you look on the left-hand side, you see really the diagnostics base business with an increase of 6%. That certainly contains diabetes care. 6% up here. Then you see the diagnostics COVID-19 sales. We had a high base last year, but nevertheless, we have grown by 24%, which I find remarkable as well.
You see pharma with CHF 1.6 billion up, very much driven by the new products. You really see the AHR erosion with roughly CHF 1 billion. Really good momentum behind core EPS development. In all transparency, you see an 11% increase. Let me explain the ingredients. I think on one hand, operations up by 2.9 percentage points. You see really the Ultomiris in-licensing agreement with Chugai giving us an uplift of 3.5 percentage points. Okay, if you do the math, you ask yourself a little bit, how can that be that the effect is so low? The point is we have a high tax rate, a high corporate tax rate in Japan of 30.5%, which is well above the average that we have in the group.
I come to that later on. That really brings the effect a little bit down. Then you see really the net accretion effect of the share buyback of the Novartis shares with 6.1 percentage points. Then we have a couple of other impacts on other. One is the financial result. Let me say here very clearly, once again, I think in the second half last year we had a major positive impact from a release of a tax provision which is not recurring the second half, and that will be certainly a drag on the core EPS growth. Okay. With that, let's go to the P&L. When we look at the P&L, I think sales is clear. Royalties and other operating income up CHF 536 million.
One is Ultomiris. What goes against it is the lower divestment gains that we have had compared to the first half, 2021. That was a CHF 146 million lower gain compared to last year. If you add that up, I think that explains the difference. The cost of sales up CHF 1.1 billion. One is volume growth. 10% volume growth, you will see that later. That accounts alone for CHF 800 million, then we have a couple of other effects I will get to. M&D +4%, here really digital, really on the pharma side. On the diagnostic side, additional distribution costs as Thomas alluded to. R&D, we have a base effect from last year.
We had development costs for Atea and for Ronapreve of exactly CHF 200 million. So if you deduct that, you see really an increase in R&D, and certainly we are prepared to invest more in R&D, and you should expect quite an increase in the second half. Then G&A, I think with a nice saving, leads us to a core operating profit growth of CHF 1.1 billion. Good. With that, let's go into the royalties and other operating income. You see here the bridge I've mentioned a couple of times already. The major green bar that you see on the slide, that's really the Ultomiris in-licensing agreement with Chugai. Not the CHF 765 million because there are also other effects here from the out-licensing income which play a role here, a minor role.
You see other operating income, very minor, and you see income from the disposal of products, which I've explained already, down by CHF 146 million. As said, we had last year in the second half, a royalty and other operating income from Ronapreve in the magnitude of CHF 654 million, which won't reoccur in the second half of 2022. Cost of sales, well, you see really quite a significant increase here, overall. Let me lead you through it. We start with the first half 2021, CHF 8.2 billion. You see really we had in the first half a positive impact from a reversal of an impairment, you know, that we have done in the past.
CHF 184 million here, a positive, which we did not see in the first half of 2022. Leads us to roughly CHF 8.4 billion, and then you see the volume increase of CHF 800 million. I think these two figures alone explain it well. Then you see really on the pharma and diagnostic sales mix that there has been an impact as well. Let me mention here that in the second half of 2021, we had quite a negative effect on the cost of sales, which came from Atea and Ronapreve, which was CHF 615 million at the time. We had it on the slide in the full-year presentation. This effect is not going to reoccur.
There is quite some positive momentum coming to the cost of sales in the second half. The other piece I should mention here is, while on one hand we certainly assume that the COVID sales go down and that applies basically to diagnostics, and that certainly means we have lower volumes than on the diagnostic side, which should also be a benefit for the cost of sales. Okay, with that, let's get to the core operating profit and margin. I see nice development here. Margin goes up to 39.2%. As predicted and expected, I think the pharma division shows an improvement here. You see really that the diagnostics division has been able to stabilize the margin on a high level.
Certainly, I think once the COVID sales go down, I think, it's very clear that there is not the expectation that this margin can be maintained. Core net financial results, I said it here, a reduction of roughly CHF 370 million in constant rates. The major point is the equity securities asset, minority investments into biotech companies, predominantly, private ones. We have a couple of listed ones as well. That came down. As said, I think, a little bit of light at the end of the tunnel. I think really, July looked promising but remains to be seen what happens until the end of the year. Interest expense was a CHF -88 million, lower than expected, so that's good.
Lower momentum than expected, but there will be a higher dynamic in the second half of the year. We have other, and that's really a little bit of a sample of topics. One major one is we have an old pension plan in the U.S. with a really defined compensation plan where we had to inject some money into. Hyperinflation for Argentina and for Turkey plays a role here. I think that's a little bit of a sample of topics. Good. With that, group core tax rate. First of all, I remember very well that I gave you guidance that the tax rate, the group core tax rate should be around 18% in 2022. Here we are.
When we look at the right-hand side of the slide, effective tax rate in the first half is 16.1%. The deviation is coming from a resolution of a tax case which gave us a positive CHF 288 million here. If you adjust for that, we would have been at 18.5%. The guidance was directionally completely okay. It's very hard to forecast these tax case resolutions because you're at the hands of authorities and jurisdiction and very hard to forecast this. Nevertheless, I think that helped us. When you compare it with the first half of 2021, we have been at 16.9%.
Here we had a much smaller impact, you know, from the resolution of tax cases, in that case, CHF 95 million. I think based on all of that, yeah, certainly I think I have to change a little bit, yeah, the outlook for the year when it comes to the group core tax rate, and the expectation is now it should be around 17%. Don't forget that we had in the second half of 2021 the major positive impact from a tax provision, from a release of a tax provision of CHF 601 million that I've mentioned a couple of times already. Good. Non-core and IFRS income had an increase in the core operating profit as shown of roughly CHF 1 billion.
You see a little bit less global restructuring plans, CHF 200 million less compared to the first half of last year. Amortization of intangible assets, a positive impact, positive deviation compared to last year. Why is that? Well, the amortization for Esbriet came to an end. Impairment of intangible assets, we have a couple of more impairments here, nothing of major significance. That gives us really an uplift in the IFRS operating profit in total of roughly CHF 1.5 billion. You have the total financial result and tax effect on the above-mentioned topics, and you get to an IFRS net income increase of CHF 900 million, which represents an increase of 12%. Cash flow. Quick comment here. You see really a very nice development, and it comes from both divisions.
Yeah, can just be happy with that number, really well how we converted all the sales and the sales increase, yeah, really into cash, and I think that's great to see. You see where it comes from. On one hand, certainly higher profits. The other piece is we also worked on working capital, and we get a CHF 600 million positive impact from that, which is certainly nice to see, very much driven by the accounts receivable. When you look at the Group net debt development, we are at a net debt level now in the middle of the year of CHF -20.9 billion, which contains, by the way, the CHF 19 billion from the Novartis share buyback. I think really a very good trend.
When you look at the free cash flows in the middle of CHF 7.1 billion, which is driven by the operating free cash flow of CHF 9.8 billion, I think it's remarkable we paid a dividend of CHF 7.7 billion, and at least the free cash flow is, how should I say, getting near to this. The impact of the dividend in the first half was much less compared to previous years. Quick comment on the balance sheet. Cash and marketable securities go down. We have repaid the bridge financing completely, which means we paid back the CHF 19 billion. We did that by reissuing new bonds, and the other piece has been cash. That's explaining the reduction here. Other current assets is inventories going up. Non-current assets is a reduction in intangible assets.
Current liabilities is a reduction in short-term debt. Non-current liabilities is an increase in long-term debt, and the equity ratio is at 33% now. Net debt on total assets, you know we're aiming at the range of 0%-15%, we are now at 24%. Okay. Outlook, very quickly. Exchange rate is clear. I think really, you might have seen it, we basically have no exchange rate impact, across the board, you can argue. You see where it comes from, a weakening euro against the Swiss franc, a strengthening U.S. dollar, an impact from Japan. You see really it nets out quite well, and gives us overall a sales growth of 5%. Good. What do you expect?
You know, that modeling here, we assume that all the exchange rates at June thirtieth remain stable until the end of the year, which is certainly very unlikely, but perhaps a good orientation, then you see really what we expect for the full year, a - 1 percentage point impact on sales, - 1 percentage point on core operating profit, and - 1 percentage point on core EPS. As said, when you look at half year, no impact at all, which is quite remarkable. Good. I think I talked about the outlook quite a bit already and tried to explain the second half of the year. We're very happy, yeah, to receive your questions now. Thanks for your attention.
Thanks, Alan. I think with that, we come to the Q&A session. The first question would come from Jo Walton from Credit Suisse. Jo, please.
Jo, can you hear us?
Jo?
Apologies. Yes, I can hear you.
Great. Hi, Jo. You have a question?
Yes, I do.
Go ahead.
Could we get some sense of when you're going to be able to present the TIGIT non-small cell lung cancer PFS data? I think a number of us thought this could be at ESMO. Would it be possible to see this ahead of a possible OS data, which I assume we'll see in 2023? Following up from what Bill said about 100% capacity and the ability to move back a little bit from that, can I ask what would happen if gantenerumab were to be successful? That's got quite a heavy manufacturing burden, I assume. A final question, if I could just ask Alan.
There was a write-off of CHF 336 million of Flatiron Health in the half. Is there anything that you can give us as an update as to maybe what's gone wrong with Flatiron Health? Is this an opportunity to update us as to what the success of Flatiron Health and Foundation Medicine are doing for your business? Thank you.
Very good. Over to you, Bill.
Great. Thanks for the questions, Jo. In terms of the SKYSCRAPER-01 data in non-small cell lung cancer with tiragolumab, I think the team is still considering what the best timing is for release of the data. As you can appreciate, because it's an ongoing study with an OS component, and it's also a competitively sensitive field, I think there's just kind of multiple complexities there. So we don't have a fixed date at this point for a presentation on that. The question about gantenerumab success and our capacity. Yeah, actually, we were gearing up for gantenerumab co-production capacity as well as other important medicines in our portfolio when COVID hit.
We were just recommissioning the so-called CCP-2 plant in Vacaville, California, which is one of the biggest manufacturing plants in the world, and it was. Basically, we were doing engineering runs with Actemra when COVID hit. It proved fortuitous because that's the plant where we produced almost all the Actemra and all the Ronapreve that we needed for the pandemic use. Basically, now we expect the demand on those two products to be much lower and so that pretty much that whole plant would be available, and that's quite sufficient for gantenerumab for quite a while. Gantenerumab would require quite a bit of protein, but the process is relatively efficient, so we feel pretty good about our capacity situation. Let's see. Was it Alan?
Alan, yeah. Do you want to comment on the-
Yeah, happy. I mean, I think it's well addressed, because it's more an accounting topic, I would argue, because basically Flatiron. I think we're pretty happy with the sales development this year. The point is when you compare it, yeah, to the original business plan that we have had, I think we have been too optimistic. Yeah, let's face it. I think that's the point here. I think really we went now through a couple of discussions, yeah, to reset this and where the business is going. We would argue, yeah, the momentum that we are seeing this year is quite satisfying. Really it's going back when we acquired the business and all the expectations we have had. This is not really the point, yeah, that we doubt in our insights approach.
I think insights is a great topic to be in, and really working on real world data is a great topic, so all that strategy is completely intact. The only thing we had to adjust is with the net book value that we had for this asset on our balance sheet because as said, admittedly, everything is coming a little bit later than originally thought.
Right. Thank you, Alan. I just confirm from my side our commitment to leveraging real-world data and advanced analytics. There's a huge opportunity in itself in the long term. I believe from a strategic point of view, it's very synergistic with our core businesses both in pharma and in diagnostics. Very good. Can we have the next question, please?
Next question would be from Wimal Kapadia. Wimal?
Oh, great. Thank you very much for taking my question. Wimal Kapadia from AB Bernstein. First, can I just ask about the Vabysmo launch, please? You know, clearly a very, very strong launch. I appreciate you cannot be specific, but when we think about the product long term, should we really be thinking about this as a Lucentis-type revenue product of, you know, CHF 4 billion, or should we be thinking of as an Eylea-type product closer to CHF 10 billion? Any context there? Then just tied to that, is it fair to assume 2023 will be a blockbuster year for the product? Then my second question is just on Polivy in first-line DLBCL. You know, the first part is can we really expect to see any real momentum for the product in the OUS markets without OS data?
Just tied to that, you know, I think, Bill, you suggested at least CHF 1 billion, and previously you talked about CHF 2 billion. Just curious, you know, what assumptions you now make for this first- line DLBCL setting. You know, what share is feasible, and which patients do you think will use the product? Thank you.
Bill, now I'm really wondering how much you lean out of the window. Over to you.
Well, let's see. Where's our crystal ball? No, I think maybe I don't know if I can give you a number, but what I can tell you is, you know, maybe how we're thinking about it and what are the reasons to believe or the reasons to be, you know, questioning whether it gets, you know, all the way up into the high single digits CHF billions. I think the reasons to believe are kind of obvious from the clinical data, right? Yeah. I mean, you could say, well, that's great for patients who don't get an extended dosing on another product, but, you know, if you've got a product like this, why would you even start with something else?
Because the other thing that we know from the clinical trials is the effect on drying of the eyes, on central subfield subfoveal thickness, you know, the anatomical impact is very evident. In fact, we're hearing all kinds of anecdotes about that from the switching that's going on in the market now, how patients who really haven't had thorough drying are.
Their doctors are seeing this after one injection, and they're, you know, calling us, calling the investigators, and saying, "Wow, you didn't tell me, you know, it was this good." The four-month dosing interval for more than 60% of patients, frankly, the fact that, you know, the biggest problem in this field is all about dosing and the fact that patients don't get the doses, they don't come in, and they lose their vision. I think for those reasons, we ought to be aiming for the sky.
The reasons to temper that have to do with the fact that there's gonna be biosimilars to both Lucentis and Eylea that are gonna be launching around the world, and so it has a little bit to do with price sensitivity, and also the trade-off between price and capacity because in, for example, in the NHS, I mentioned, almost unprecedented, that we got approval from NICE the day we got regulatory approval in the U.K.. I think that's the first time that's ever happened for us, and, you know, it's almost the first time it's happened in the world. That's really about in the U.K., they just don't have the capacity to do the injections. You know, again, patients lose their sight.
Look, I'm bullish, and I'm thinking big, but I guess it's the analyst's job to figure out what the number is.
I'm gonna take that as CHF 10 billion. That's fine.
That's great. And then Polivy, you asked about, you know, without OS data, will ex-U.S. adoption occur? I think so. I mean, it's been a long time since R-CHOP launched. What was that? Almost 20 years ago. You know, this is curative intent. I mean, we're talking about first- line DLBCL. These are middle-aged people who have a basically disease that can be cured, or if it relapses, it's usually gonna be terminal. You know, now we have better second and third line therapies that can postpone that. You know, basically, you have a chance to cure a person in the prime of life, and they're done forever. Or if they have a relapse, then they're gonna have this disease, and they're probably gonna die from the disease.
As I showed you from the Kaplan-Meier curve, you're talking six, seven, eight patients out of a hundred as that curve matures, and then the OS curve will come in. You know, we should see similar things. I think the fact that people take this very seriously is underscored by the fact that the EMA moved so fast to approve it. Japan's gonna approve it in August. We'll have approval by the FDA later this year. Just to clarify, I said more than a billion, but I think the total Polivy potential, including the use in later lines as well as the Polivy is probably closer to two than one. We'll see.
Thank you.
Thank you. Perhaps I can also add here, now that I get into this phase of looking back, of my CEO tenure, there have been two. I mean, those who know me for a longer time, they know that I typically are not, I'm not super optimistic and, you know, I'm careful because I know that many things can go wrong and I've seen things going wrong a lot of times. I tend to be on the careful side. There were two instances where I was more optimistic than the investor community when I saw the first consensus coming in, and where we had debates with investors. That was Perjeta.
This was after the affinity trial, where I was really certain and I also spoke out in a very untypical, optimistic way, about the potential of this medicine. The second one was Ocrevus. I remember the initial estimates being relatively low, and we all were convinced that this is a really fundamental change in the way MS is going to be treated. I put Vabysmo into this category. In my discussions with ophthalmologists on the initial feedback I get from the community, I think this is a fantastic medicine and it has really a great potential.
To see this now confirmed already so early with the launch in the U.S. and to see the uptick in some other markets, you know, where it's starting to get it out to patients, again, this is one where I'm exceptionally more optimistic than the investor community used to be. Anyway, on that note, Bruno, the next question.
Were we able to answer your questions?
Yes. Great. Thank you very much.
Okay. Next one would come from Sachin Jain, Bank of America. Sachin, please.
Hi there. Thanks for taking my questions. I'm gonna kick off with a big picture one first, if I may. A lot of investors we speak to perceive risks around the growth profile if TIGIT and gantenerumab both fail, given the pressures we know, COVID decline, pressure to count Xolair, Lucentis as bridge generics. A lot of the presentation and prior answers have talked about the strength of pharma launches and the diagnostics-based business. The very simple question for me is how does all of that balance out for you in your mind in the next two, three years? 2023 specifically, do you have an ambition to grow given the substantial COVID decline? How should we think about the next two to three years without any TIGIT or gantenerumab launches? That's the big picture. Two specifics.
On gantenerumab, I think, Severin, with your cautious hat, you've talked about this as 50/50 before, any shifts in that thought process as we get closer to data. Then the final question also, I guess, for Severin specifically is on TIGIT. I think investors through roadshows, post results have received mixed messaging as to where you sit on TIGIT in terms of the missed PFS, but clinically relevant OS possible. Severin, from your seat, where do you sit on commercial potential, and how sort of disappointing was it not hitting PFS? Thank you.
Okay. So on the first question, it's a bit of a difficult one because it will very much depend on COVID. You know, if we lose COVID-related sales altogether, I mean, you can do the math, then it will be you know a steep curve for next year. Even though we see fantastic growth with these new medicines, even though there's the Vabysmo opportunity and others, I think it will be tough. If we have some tail business, if potentially you know COVID goes into next year, who knows? I think growth is possible next year. That's how I would frame it without you know making a guidance prematurely.
Now, if you look beyond that, as soon as we have washed out this COVID effect, then I clearly get very optimistic because, you know, not only get we over the COVID washout, but also, you know, the impact of biosimilars will come down. I see no reason why we should see, you know, a declining momentum for our franchise. On the contrary, there's a lot getting online, as we speak. 2023, you know, we always said this year might be a transition year, that last year might be a transition year, and then COVID kicked in, and then suddenly we had to start all over again. Now, of course, the success of today is getting the hurdle for tomorrow.
If we wouldn't have had COVID, if there was no COVID over the last two years, I can guarantee you we would grow next year, right? I remember I was once saying in 2023 we will grow, and we would grow if there was no COVID effect. Now with COVID, which we could benefit from and hopefully also made some contributions for healthcare and societies around the world, you know, it's a bit more of a challenge in relative terms. Certainly in absolute terms, I'm very... How should I say? I think we're very well-positioned with all the risks, of course, which are always there. As far as gantenerumab is concerned, no, my view has not changed. I think it is a high-risk project.
I mean, I'd say we plan for a situation where it doesn't come through. It's not that we have any more information than you would have, but I think it's prudent, and it's the right thing to do. Of course, if it is positive, that could be transformative and we are in a completely different situation also from a growth perspective. That's you know here the more how shall I say prudent part of me is dominant where I say, "Let's hope for the best, but let's don't plan on that basis." As far as Tecentriq is concerned, I mean, let's face it, this was a setback and we were all extremely optimistic.
I was personally very disappointed because, you know, when you see phase II results as we have seen for tiragolumab, then of course you are confident that it will also be confirmed in a late-stage trial, which was not the case. We didn't hit statistical significance. That is a setback because at the minimum we have lost a year, right? I mean, if we would have had positive PFS, we would have been to the market probably earlier. As a result of it, that would certainly have been beneficial in itself. We would have had a better start in terms of our market share position, et cetera. Now we'll see how it plays out.
In case that overall survival is positive, I think we can still salvage a lot of value of tiragolumab. The reason is simple, because at the end of the day, of course, overall survival will always beat progression-free survival. I mean, progression-free survival at the end of the day is a surrogate biomarker. What really counts is, do you live longer? It's more important if you have both endpoints, then is the tumor growing and at what time is it growing again? I mean, as a patient, you don't care. What you care about is how long you live and at what quality of life you live. We will have those data next year.
We have lost time as a result of not hitting PFS in a statistically significant way, even though we saw a positive trend. That is a setback in itself. It has certainly also lowered PTS for OS. The jury is still out, and if we do hit OS, I think this will still be a great opportunity for patients and certainly for our business. Thank you.
Thank you very much.
Next questions would come from Richard Vosser.
Hi. Thanks for taking my questions. First question just on the adjuvant trial for Tecentriq. The head and neck seems like obviously delayed, but seems like there was probably an interim analysis this year. Also renal cancer, as you said, hasn't hit. Just thinking about your confidence in the remaining Tecentriq adjuvant trials, and particularly head and neck, given it's been pushed out a little bit. Second question, just on diagnostics margins. Margins in first half very similar to second half. Clearly COVID revenues going down will reduce the margin, as you say. You know, should we be thinking about 20% margins this year and then a decline next year? Perhaps some shape of the curve there. I'll probably stop there. Thanks very much.
Thank you. Bill?
Yeah, sure. Let's see. In terms of the adjuvant studies. I think this sort of scales with the effects in the metastatic setting. You know? For example, one of the readouts we'll have in the second half is adjuvant liver cancer, and, you know, I think the Tecentriq plus Avastin data in metastatic liver cancer was quite unambiguous. You know? Really big impacts on PFS, OS, very, very clear result. That makes us pretty bullish in adjuvant. You know, in other indications like RCC where the data's been a little more mixed, then, you know, maybe it's not as surprising that the adjuvant readout would be, yeah, less strong. I think in head and neck cancer, I mean, basically there we have an IDMC. They've looked at the data and said the trial should continue.
You know, if they had looked at it and said it was futile, then the trial wouldn't continue, and we'll have to wait and see what we learn in 2023. You know, I think we've got some things ahead of us still with Tecentriq, and I would say, Severin, if you challenge me on this if I get it wrong, but like, for example, when you said we're not planning for gantenerumab, we're not counting on it.
Correct
We're definitely, you know, gearing up for it.
Yep.
That's what you do when you have a sort of 50/50 thing. You know, from an operational standpoint, we absolutely. You know, we have teams. We're working on all the things you work on in terms of health economics and access approaches in different countries and obviously manufacturing preparations and things. I think the point you made is right on, that we're not reliant on gantenerumab. In fact, it's not even that significant even in a positive case in the next 18-24 months because we would just be launching out at the end of that period. And then I would just say on tiragolumab, as Severin said, the OS, you know, that's a big part of it.
That's why we put most of the alpha on OS and, you know, I think there's more than 10 cancer immunotherapy studies so far that missed on PFS and hit on OS, which is why we use co-primary endpoints and why we put most of the alpha on the OS because at the end of the day, that's the one that counts. You know, I think I don't know if the message has been received in a mixed way, but I think, yeah, we have reasonable confidence that we'll have a positive outcome on OS. You know, we won't know for sure until we get it, but until then we're still optimistic about tiragolumab.
Thanks, Bill, and thanks for clarifying the important points on gantenerumab. Very important. There was another question on the diagnostics side. Thomas.
Exactly. The question was on the Diagnostics margins. Yeah, I think the way you're thinking about it is also the way I was thinking about it. That will stay above 20% for this year. In fact, when we were managing the P&L for Diagnostics, we were always managing excluding COVID sales, right? Because we know that COVID sales can go up, can go down, and so we try to manage costs diligently based on the base business, actually. If you actually look back in, I think 2019, we had margins of 13.9% in Diagnostics. Going to 20% excluding COVID would be a huge jump.
what I can say is that we've made huge progress in really managing our P&L, and we have significantly improved our margins just, you know, excluding COVID. Not quite to 20%, somewhere in between where we were and the 20%. I mean, if I look at our P&L, how much money we're investing in R&D, I mean, this is the reason why we're not yet at 20%, but we have so many important programs currently in our pipeline that are really exciting like mass spectrometry, just to name one of them. They're, you know, will be not in the too distant future. We really wanna see that through to make sure that these products have the impact that they can have.
Thank you. Can we have the next question, please?
Yes. Maybe a question I will take from the chat, and it goes to you, Thomas, follow on diagnostics. Do you have visibility that the additional Cobas machines placed through the pandemic are still active and now used for other purposes? This question comes from Luisa Hector from Berenberg.
Yeah. We actually have all of our systems, or let's say 90% of our systems are connected to our IT systems. We do see the usage of those machines and we see that they are being used. What we also see is a lot of consolidation on these kind of instruments. Why do we see the consolidation? It's, you know, the high level of automation, the high throughput, and the menu that we have. We do see that, you know, this is the primary choice. By the way, another way I see that is that, you know, looking at how many systems we placed in the last couple of years, you may think that the demand for these systems is going down, but that's not the case.
We're still producing more of those systems than we did pre pandemic times. Now on top with the cobas 5800 launch, we have even more opportunity in the segments where actually you know it's more suitable for, let's say, countries in Latin America or Asia with the 5800 or smaller European countries in terms of throughput. You know, I'm actually very positive if I look at you know how the instrument placement is continuing.
Thanks. Next question would come from Keyur Parekh, Goldman Sachs. Keyur, please.
Thank you. Hopefully, you can hear me. Severin, you kind of mentioned, as you kind of look back at your tenure as CEO, I wanted to ask you kind of a slightly more forward-looking statement. As the chairman or the future chairman of Roche, and as you look at the next decade, what do you think are going to be some of the critical changes to the structure of the global kind of industry? Do you think there will be fewer pharma companies than there are today? Do you think there'll be more pharma companies? And what role do you think kind of Roche will play in that new structure?
Separately for Bill, as we look at kind of the bispecific antibodies, and you kind of were very keen to point out that the indications we are seeing in the near term are very much kind of the top of the iceberg, and there's a lot more to go. I'm just wondering, kind of as you look at the broader competitive landscape for agents like this, what gives you the confidence that Roche have a differentiated asset here? Then lastly, for both of you, Roche spends more on R&D than any other company in the industry. I'm curious to hear your thoughts on what the trajectory of returns on R&D investments at Roche have been over the course of the last 10 years, and what justifies you continuing to spend at 500, 600 basis points ahead of industry average.
Thank you.
Okay. Thank you, Keyur, for your questions. I think actually the last question and the first one is connected. I do believe that going forward, at the end of the day, what counts is that we maintain our power to innovate. That's really what drives growth in the long term, both in pharma and in diagnostics. It's all about translating cutting-edge science into breakthrough potentially life-saving curative medicines in the best case, and novel diagnostic solution. That's what it is about. We will continue to focus on that. I do believe that you know, there's a lot of people who say, "Well, is there an end to innovation and this tailing off," et cetera.
I really don't believe so because the complexity of the human body, the complexity of diseases is enormous, and we have only scratched the surface. There is so much more we have to better understand and couple that with this human kind of curiosity. Those two things, if they come together, humans who are curious to make progress, to understand, and having such a complex challenge to solve like how the human body works or actually doesn't work if you have a disease, that cries for further progress in science, and that will continue, and we want to be part of that. That will be absolutely vital.
I think there is one component which we can leverage now on top of it, which is relatively new to our industry, and it was touched on earlier. That's around digitalization. There's no doubt that healthcare will get more digital. We can leverage data from the real world. We can leverage new advanced analytic tools. And that again will help us to innovate and to tackle diseases which we couldn't tackle in the past. Now, your question on do we see fewer or more companies, I don't think that in the pharmaceutical industry, it is about scale. I think it is much more about ingenuity, creativity, resolving a specific issue, discoveries. And you see that over and over again.
Also very small groups, if these are talented people, they can innovate, they can make progress, and therefore, I also think that there will not be a consolidation as you see in other industries like in the generics industries, where it is much more about economies of scale. In our industry, we will see and we will continue to see smaller companies popping up, and I don't think that there will be a big structural change, and I'm talking about the innovative industry, right? Yeah, it's about innovation. It was about innovation in the last 125 years, and I think it will be about innovation as we go forward. Bill, anything to add on that?
I think you said it really well, and I think the other thing, Keyur, to remember is that we didn't just increase R&D spending. We took down everything else, and you know, again, we just think that's the future. As Severin said, we gotta innovate our way to the future. We're putting a huge amount of energy into how do we better spend the R&D money. So again, we don't think it's just like, oh, we're gonna spend more. We need to make sure that it counts. So we're investing in foundational investments like the Center for Human Tissue.
What is it? Sorry.
Translational.
Yeah, thank you. Human Translational Biology, which is like the Organoid Center. It's probably going to be the biggest thing of its kind, which is, you know, trying to get to much better models that'll be much more predictive of what's going to happen in the clinic and less reliance on animal models. You know, the work we're putting into computation and analytics, I mean, these are all things to increase PTS, to decrease cost, to reduce cycle times. It's all of that. You asked about the bispecific antibodies, and I agree, it's a very crowded field, and I think anyone could be confused in hematology of wondering like, well, you know, how's anybody going to make money here if there's so many options and so many alternatives?
I think the reason we believe that we can really lead out here and actually make a viable business of it as well is twofold. One is just in oncology, it's still first past the post, you know. If you're second with some efficacy result, I mean, nobody cares. You get 5% market share. If you're first, you get 70% market share. We're first with mosunetuzumab. We're going to be first with glofitamab. We're first with Polivy. We have Gazyva. That comes to the second point, which is combinations and surely combinations are going to be the key. We think we have a lot more faith, for example, in combinations of two or three off-the-shelf medicines versus CAR- T, which requires, you know, a much more elaborate process.
I agree. It's a bit confusing if you look at the field, but I'm really positive on us emerging with a really strong business.
Can we have the next question?
Yes. Next question comes from Andrew Baum, Citi.
Thank you. A couple of questions for Bill. Firstly, on tiragolumab and SKYSCRAPER. You disclosed qualitative comments about PFS and OS being numerically greater in the tiragolumab arm. You are in possession of the response rate. Could you say anything on a qualitative basis similarly on the response rates in the two arms, the depth of the responses and the durability of the responses that would help inform us in anticipation for the maturity of the survival endpoint? Second, Roche has a legacy in infectious disease. Obviously, you know, you are a dominant player in COVID-related diagnostics. You have more biologic manufacturing capacity than anyone else. Where I'm going with this is there's a sizable market for antibody prophylaxis for patients at high risk of COVID that plays directly into your hematology, your solid tumor franchises.
Evusheld is the only player out there. Why hasn't Roche entered this market given, seemingly, you have all the tools required and a group of patients that's going to need therapy forever, given the poor response to monoclonals? I'll stop there. Thank you.
Thank you. Bill?
Sure. I'm sorry to say, I don't think we can really disclose any more on tiragolumab at this point. So I'll look forward to being able to share all of that. In terms of your question about prophylaxis and antibodies, you know, this really has to do with the trajectory of the pandemic and the mutations. So, you know, we and our partner Regeneron were very far down the path with prophylaxis. We had data out to eight months from a single dose of Ronapreve, looked great. By the way, it might look great again, depending on what the next major variant is, because you remember that Omicron was not descended from Delta.
Omicron came from an earlier variant, you know, we had great efficacy against Delta, but then when Omicron came, it kind of wiped us out. I know the fact, you know, if you have an antibody that works against the present prevalent strain, then you can get that indication or that application. If we started right now to develop an antibody for Omicron, you know, there's no way by the time it was out that Omicron's still going to be the thing. That kind of the problem. I mean, there are some protein engineering approaches to try to design around that, but I don't think we're confident enough in that to go whole hog in.
It's not to say we're not, you know, we're still evaluating this with Regeneron, with Chugai. You know, we have our scientists are looking at it and working at it, but I don't want to promise anything in the near term.
Thanks, Bill. Next questions would come from Emily Field, Barclays. Emily, please.
Hi. Thanks for taking my questions. Just a follow-up question on the guidance. I appreciate that there's a lot of mechanical moving parts, but just wanted to confirm that, you know, if there was any components of the business fundamentally that have deteriorated since you gave the full year outlook, you know, are you allowing more room perhaps given the volatility of lockdowns in China? Did the lockdowns in China have any material impact on the pharma business in 2Q also? Then just on the guidance for AHR, you know, annualizing the first half would suggest an erosion closer to CHF 2 billion. Any reason to suspect acceleration there, in the second half? Thank you.
Right. Yeah. The short answer on the guidance is no. The underlying business is doing very well, but perhaps, Bill, you can comment specifically on China.
Yeah. In China, we saw some impact in Q2 on the pharma business, but it wasn't particularly severe. I think maybe because, well, I would say we worked heroically. Our people there, I think we had like, 100 people who spent 75 days and nights at the plant, you know, sort of sleeping on cots and things to keep the product flowing. The patients, even if they were on lockdown, they were still able to get their medicines and things. The main impacts, pluses and minuses in China, we have growth of new medicines and AHR biosimilar impact, which is a drag on things. Yeah. Then you asked about acceleration, in fact, of AHR and the outlook.
I think we're looking at international, possibly China could be accelerating, and so that's why we've maintained the guidance.
It is, I mean, it is roughly CHF 2.5 billion and probably that is the higher end of the expectations as we see it today. Good. Can we have the next question?
Yes. Next questions would come from Steve Scala, Cowen. Steve?
Thank you. Can you hear me?
Yes.
Yes.
I have two questions. Thank you. First, I apologize. I'd like to go back to the OS trend in SKYSCRAPER. Bill, first, can you confirm that you have seen the curve? The question is, management's very tempered tone suggests the trend is barely there. There were no optimistic words chosen at all to describe it. Since we have nothing else to go on at this point, would acknowledging your trend be the most accurate metric that we will have until we see the data? The second question is on Hemlibra. Does any of the recent competitive data, either from Sanofi or Novo, concern you? And if not, why not? Thank you.
Bill?
Steve, I can't really answer your question specifically, but what I can say is you've probably heard two kinds of things from us about tira. One kind of thing you've heard is us explain sort of in detail about co-primary endpoints and, you know, allocation of alpha, that we put more on OS and that kind of thing. Then you've heard from us say, "Hey, we've not given up on this." Then the other thing you've heard from us is our, you know, sort of normally conservative thing that we say about anything that's uncertain, is we say, "Well, it may not happen. It may not work." I don't know. I don't know what else to say, but I think the fact that we're still talking about it would should suggest to you that
Like, for example, if we say, "Yeah, we're still reasonably optimistic, we could have a medicine here," that means we're reasonably optimistic that it's going to be a medicine and that this is Roche talking, and you know, translate it accordingly. In terms of Hemlibra and competition, I think the modified factor product, I think remains to be seen what that's going to look like from an inhibitor standpoint, because as you know, you know, if you have hemophilia, you don't want to develop inhibitors to factor eight and highly engineered medicines tend to be more antigenic.
I think probably the field is going to want to see a considerable amount of real world evidence and see what does actually happen in terms of inhibitor formation before that would be, you know, sort of like wholesale switching, just like we saw with Hemlibra. You know, there was a cautious uptake. If you're going to have a condition for your whole life, and you have options currently available like Hemlibra, you know, I would submit the patients who have stuck with their factor and haven't switched to Hemlibra may not be the ones who are going to rush right out and go with a highly engineered factor product. In any case, we don't think they're going to take Hemlibra patients.
It'd be more that, you know, there would be competition within the factor space. That would be our read. Congratulations to Sanofi on a good trial and a nice looking product. The other one you mentioned is just farther out. I mean, we're talking about a launch somewhere out in, I guess, 2025 or 2026, in that kind of timeframe, and a lot can happen between then and now. You know, when you're adjusting the level of clotting factor or a pseudo clotting factor, you know, things can go wrong and you can have downstream effects that are unpredictable.
You know, I think again, if we have like now I think we have about 18,000 patients worldwide on Hemlibra, and what we hear from them is they're very satisfied with their therapy. I think it's unlikely they're going to be quick to switch to something else that's not materially different clinically. You know, by the time those products would come, Hemlibra's gonna had you know, two or three more years of penetration. Bottom line is we feel really good about Hemlibra standing and think it's going to continue to grow for quite a while.
Thanks, Steve. Yep. Next question would come from Mark Purcell, Morgan Stanley.
Thanks very much, Bruno, for taking my questions. I have three. Firstly, on Vabysmo launch dynamics. Clearly you're very confident in the potential of the product, and the question is, how quickly should we expect share to be gained? That gives us a degree of extra confidence in the product as well. Could you help us understand the sort of initial patients that are switching, the reasons for that, whether it's injection burden or whether it's an efficacy consideration. You talked to the J-code coming into effect on the 1st of October. Beyond the net pricing effect, should we expect another uplift there to your annualizing sales rate of CHF 500 million at the moment? Are you seeing any sort of dynamic differences between AMD and DME?
Just sort of more color on Vabysmo would be really helpful. Thank you. The second one is on tiragolumab. I'm not gonna ask you about survival curves and things like that, but given you've got a one-year head start in terms of understanding from the experience of SKYSCRAPER-01, could you help us understand how you're looking to build on that experience? Are you looking to introduce more combinations to partner Tecentriq and tiragolumab, whether it's to improve the depth of responses or whether it's to target sort of T-cell exhaustion pathways that could generate resistance like CD226, for example. And then the last one is for Thomas. Could you provide us a breakdown of COVID sales in Q2 of rapid antigen versus PCR?
The reason for the question is to try and understand where the base of the more stable and more durable sales component is, while we appreciate the fact that your guidance assumes little contribution from COVID diagnostic sales in the second half of the year. Thank you.
Thank you. Bill.
Yeah. Thanks, Mark. Yeah, let me describe how I would see the Vabysmo, you know, kind of dynamic. The initial dynamic for the first couple months was, will you get reimbursed? And so, you know, that was a period of, you know, real hesitancy in the retinal specialists. You really only had the kind of leading adopters using it. And there, they were really only using it for patients where they're really having breakthrough disease and, you know, very problematic on efficacy. That was sort of the initial. We started seeing reimbursement coming in. The word was getting out in kind of April that, yep, this drug's getting reimbursed. In the meantime, we've managed to get 80% of the commercial payers are on board as well.
Now, you know, we started seeing switching that was not only where you had breakthrough disease, but also, you know, for example, patients that need monthly dosing. I think looking forward that we should see, you know, basically more patients that are requiring, let's say, every other month dosing or every three-month dosing or also naive patients. You know, why would you start them on something else? I think we can look forward to that dynamic. Finally, the J-code will kick in on October 1st, which will mean that the prescribers who use relatively less or treat relatively fewer of these patients, maybe are waiting to see that that'll kick in as the additional real world safety evidence comes in. That should also drive momentum and breadth of use.
Finally, we'll have international expansion. As I mentioned, Japan, U.K. have already launched, and we'll have many more countries coming online. We should have EMA approval in September, so we'll be really covering a large part of the world at that point. Tira combos, we're not really discussing that. You know, what other things we would do with Tira right now. We're definitely contemplating that with the data we have, and we'll look forward to saying more about that in upcoming sessions. I'll turn it over to Thomas.
Yeah. Thanks for the question. In Q2, we still had quite a lot of rapid antigen sales. More than two-thirds of the sales were rapid antigen sales. And I agree with your comment that the more stable business is PCR. And the reason is simple. I mean, if I just look in Q2 alone, you know, one government ordered for CHF 550 million, right? That was one customer. And if that one customer doesn't reappear, you know, you're missing CHF 550 million. Because, you know, governments are currently not investing anymore into rapid antigen tests, perhaps it will change again in Q4. Let's see how things develop. I mean, we were talking about, you know, potentially new variants appearing, maybe hospitalization going up.
The reality is that you have very few customers with very high orders. There is a very high volatility. PCR, these are, I would say more normal customers that we had pre-pandemic, labs, hospitals, et cetera, and thousands and tens of thousands of customers, so it's more stable situation. I would agree with that assessment. Now, also keep in mind that, now people don't have to test anymore when they go in quarantine. In some countries, they don't have to quarantine at all. There's no more testing before flights, so there is an impact also on the PCR side from that aspect.
Thank you. I think, Bruno, we are really running over time. We have to bring it to a close now. I'd like to thank you very much for your interest. I'm sorry for running over time. I know there are still a couple of questions in the queue. I would suggest that you directly get back to Bruno and his team. I wish you a good day. Thank you very much. See you next time.
