Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Samir. And thanks everyone for joining today's conference all. With me today, I have Felix Ehrat, our general counsel, Harry Kirsch, our CFO, Richard Francis, who leads out Sandoz business, Paul Hudson, who leads our pharmaceuticals business. I'd like to welcome Liz Barrett, our new head of our oncology business and Mike Ball, our head of Alcon. Today we're gonna use a little bit of a different format. We'll have more of an abbreviated presentation, so we have more time for a Q and A with all of you. And we hope this allows for a better exchange. Now moving to slide three, you saw this quarter we began executing a series of deals to focus our use of capital and focus our company. And this is in line with the stated priorities I laid out in January, that we wanna become a focused medicines company powered by data and digital technologies.

We started in January with the closing of the acquisition of Advanced Accelerator Applications, a novel therapeutic for neuroendocrine tumors and a subsequent launch of Lutathera from AAA. We licensed Spark, the first gene therapy for an ophthalmological condition. And in March, we agreed to divest our OTC JV stake for $13 billion. We also announced a digital collaboration with Pear Therapeutics, which we expanded earlier this week to build out our capabilities in digital technologies. In April, we announced an agreement to acquire AveXis which gives us a platform now in gene therapy and builds out our neuroscience portfolio. So, as you can see, we continue to progress on this strategy and look for bolt-on opportunity in line with our capital allocation priorities. Now moving to slide four, we also made a number of new appointments to the executive committee to support our strategy and support our strategic priorities.

John Tsai joins us. He's a physician executive with over 17 years of experience building and leading high performing teams. He joins us from Amgen where he was chief medical officer and senior vice president of global medical and overseeing all clinical and medical functions. He brings to us strong clinical development capabilities, strong medical affairs knowhow, and a strong mindset around data and digital technologies. Second, we had Steffan Lang, who joined Novartis is 1994 promoted to the ECN as global head of manufacturing. This will allow us to put a bigger focus on manufacturing, improving our manufacturing footprint and delivering on the cost improvements and reductions in cost that we've committed to and that we plan to continue to drive through the coming years. We moved Bertrand Bodson onto the executive committee as well, in line with our priority to be a leading company in data and digital in our industry.

And he's had prior experience with Sainsbury, Argos, Amazon, and EMI Music. And finally, we've also moved Shannon Klinger up to the ECN as well to elevate the importance of ethics, risk, and compliance at the company. She's been at the company for many years as well and comes with a deep understanding of our compliance environment as well as a strong legal background. All these appointments are in line, as you can see with the five strategic priorities that I outlined in January. Now moving to slide five, when you look at our performance in Q1, we delivered a strong performance across all operational and financial key metrics. Sales and core opinc were both up 4% in constant currency with a nice foreign exchange upside as you can see from the figures. On opinc and net income, it's important to note we had an impairment in 2017, so lower prior year base but nonetheless, a very strong performance.

And core EPS grew ahead of core opinc in part due to the share buyback that we've done in previous years. So, overall, strong financial performance across all key metric and sets us up for a strong year. Now moving to slide six, when you look across our growth brands, we continued our sales momentum in innovative medicines across all our key growth brands. We're quite pleased with our progress. And I'll go into a little bit more detail on a few of the key products, particularly Cosentyx and Entresto as well as the strong growth we saw in oncology.

Now moving to slide seven, looking at Cosentyx, you can see that we had a strong Q1 performance when you look at overall performance from an NBRx standpoint. In rheumatology, which we define here as AS and PsA based on IMS and Symphony data, you can see that we have the highest NBRx share at 42%. In dermatology, we continue to see strong performance relative to some of our key competitors with 17% NBRx share. We're also pleased with our performance to date when you look at new patient demand. It increased by more than 40% across our indications. Now I'd like to say, we continue to believe in the trajectory of Cosentyx. We believe that Cosentyx will reach in line with what consensus currently has out there. We look at the business, and we look at the performance, and we feel very confident about the volume growth.

Most of the variability you've seen and that I think have been commented on this morning were due to inventory destocking at the specialty pharmacy in the US. And Paul can get into that more in the Q and A. But the biggest sentiment I wanna leave with all of you is our confidence in the product and the confidence in the outlook. And from everything we see both in the US and Europe, we expect to deliver based on the expectations that we've set forth.

Now moving to slide eight on Entresto, we have strong momentum continuing in Q1. You can see that for the first time, we cleared 3000 weekly NBRx in the quarter. We delivered Q1 sales of $200 million. And importantly, we also continued to generate more clinical and real world evidence to support Entresto's profile. We released new data that showed the reductions in hospitalizations, improvements in quality of life, as well as additional data that showed Entresto's impact on renal function. Taken together, we think now we have Entresto with strong momentum, we're now one year into having a primary care sales force out in the US. When you look at ex-US as well, we see strong growth. So, we feel quite good again about the trajectory of Entresto to be in line with the longer-term expectations we've communicated to all of you.

Now moving to slide nine, in another important trend we've seen now in the first quarter that oncology returned to growth with 6% growth in constant currency. Now this was driven by a range of strong performance in our product line, starting with Promacta and Revolade, where you saw 41% growth in constant currency with $257 million sales end of quarter. Tafinlar and Mekinist are leading products for BRAF mutant melanoma, and other BRAF mutant cancers continued to have strong performance. And we filed for adjuvant melanoma in both the US and the EU. I would also like to note that we had a very strong performance in the quarter from Jakavi as well as good performance from our launch brands Rydapt and Kymriah. Now I also wanted to comment on Kisqali. Kisqali's off to a solid start. We've launched in a number of countries in Europe close to our competition in the CBK46 space.

In the US, we continue to see growth in new prescriptions. And I think the key thing now for us and for Kisqali is gonna be looking at the MONALEESA-3 and MONALEESA-7 data releases as well as that getting fully reflected in our labeling to see how can Kisqali then compete moving forward in the US. And I think Liz will be able to comment more about that in the Q and A. But overall, the oncology business is back to growth, and we feel very good about where we are overall with that business.

Now, moving to Sandoz on slide ten, Sandoz performance was a mixed picture over Q1, as you can see here in the chart. We continued to see strong performance outside the US with 5% topline growth, but the pricing pressures continued in the US. And it's clearly a difficult environment. Our US business is a good business. It's a business that we've built up over the years. We have strong capabilities, strong talent, strong portfolio. But we do have a challenging external environment, which is normal, I think is the cyclical environment of the generics business. Now importantly, we did receive FDA approval for Glatopa 40 earlier than expected.

Now with the situation at the McPherson site, which I think has been well described, we've had to build inventory to support the US launch. And we do expect an acceleration in sales as we move through the year. We also received a positive CHMP opinion for Infliximab, so our biosimilars portfolio continues to expand in Europe. We look forward to additional approvals later this year in both the US and Europe. Now one other update is that we did receive a CRL for Advair Gx. And we've evaluated that CRL and also had the necessary calls with the FDA. Based on everything we see and the plans that we currently have to address the deficiencies that the FDA identified, we believe that we have line of sight to launch before the end of 2019.

Now moving to slide 11, Alcon. But before getting into the details of Q1, I did wanna take a step back and say that I've had the opportunity now to visit our teams all around the world but importantly, our Alcon teams and our Alcon sales and marketing teams, production sites. And I've been very impressed by what I've seen. Alcon is the leading ophthalmology device company in the world. We have great capabilities, a great legacy, strong customer relationships, strong understanding of customer dynamics and of our products. So, I think what you're seeing now reflecting in our numbers is the strength of that core capability in this business and something I think we're very pleased with now the progress that we're making that Mike and his really, world-class leadership team have started to deliver. So, in the quarter, you saw continued strong growth and momentum reflecting the execution of the turnaround plan. We had 7% topline growth, 29% growth in core opinc.

Our core margin grew to 20.2% for the quarter. Now in part, this was due to a weaker comp in the previous year. So, I think it's important to note that as we get through this year, we're gonna have stronger comps in 2017 reflecting the turnaround that started mid of last year. But this result was driven by strong performance both in surgical and in vision care. Overall, we're optimistic about the outlook. I think you also see the impact of moving over the OTC products, which gave us a 3% lift on our core margin. When we look forward on Alcon right now, our expectations is we believe this business will trend in the low- to mid-20s in terms of core operating margins in the midterm and to the mid-20s over the long term in line with what we see overall in the industry.

So, moving to slide 12, we've also made significant progress in Q1 on our potential blockbuster launches. And I wanted to give an update on a few of these. First, as I mentioned, Lutathera received its approval in neuroendocrine tumors in the US. Kymriah and DLBCL remains on track for US approval in Q2 of this year, as does Aimovig, our first in class CGRP monoclonal antibody. We also filed ACZ885 for CV risk reduction in both US and Europe. That filing was completed in December. And we're on track to complete a rolling submission of BAF312 and secondary progressive MS in Q2 and RTH258 in Q4 of this year. So, you can see taken together, 13 potential blockbuster launches assuming a closure of the AveXis transaction. So, a very strong profile that we believe can drive the growth for the next five years and beyond.

So, going to slide 13, when you look at those launches, it's important to note our ability to leverage our existing infrastructure and commercial infrastructure across these launches. This is a situation where we've built up to the strength and depth in each of these therapeutic areas. We have existing sales forces. And as we bring these new launches on, we're leveraging existing infrastructure We believe this will help us drive the core margin expansion that we've outlooked in January because we won't have to build up new sales force and marketing capabilities but can really leverage the strength of the business that we've built. Now importantly as well, we've added new platform therapies to the company.

In particular, AAA with radionuclide therapy that we believe can be applied to multiple cancer types beyond neuroendocrine tumors as well as with AveXis, which will allow us to hopefully, if closed, expand beyond only in neuroscience to other monogenic neurological disorders, but also can support our efforts in NIBR and ophthalmology as well as other disease areas. And of course, we have continued to expand our efforts in CAR-T cell therapies and related therapeutics that impact cancer care. I wanted to take a little deeper dive on Aimovig because it is an upcoming launch with the potential to transform migraine prevention across the spectrum of episodic and chronic migraine. It's potentially the first monoclonal antibody to launch in the US. We believe the FDA action would happen in May. We have field teams in place to capitalize on our first mover advantage. And the other thing I wanted to highlight is that we are a leader in CGRP science.

And you saw that earlier this week with the release of our LIBERTY data. This is the first in class data that has been generated in patients who have failed multiple lines of previous therapy. What that allows us to do is to go to pairs and say, "Look. We have data that shows that in patients who failed existing therapies which are largely ineffective or not well-tolerated, we've shown that we have a substantial impact on these patients' wellbeing and quality of life." And I think that's gonna be an important element of our story, both in the US and in eventually in Europe to drive Aimovig's success in the market. Now with that, I'd like to hand it to Harry to go through some of the financials.

Harry:

Yeah. Thank you, Vas. Good morning. Good afternoon, everyone. So, moving to slide 15, we are confirming our group and division 2018 guidance. As you have seen at the group, we grew sales plus 4% in constant currency in quarter one, which is at a level of our full-year guidance of low- to mid-single digits growth. Now by division, innovative medicine sales were up plus 6% in quarter one, tripled by the growth plans. We expect this to continue for the rest of the year and innovative medicines to deliver to mid-single digit growth in full-year 2018. Sandoz declined in quarter one as expected due to competitive pressures in the US. We continue to expect 2018 sales to be broadly in line with prior year to a slight decline. Alcon expect to grow low- to mid-single digits in 2018. As you have seen, Alcon grew strongly in quarter one. But please keep in mind as Vas mentioned that the business started to turn it around throughout 2017, so our quarter one '17 was a bit of a low base.

For Q4 operating income, we confirm our guidance of mid- to high-single digit growth for 2018. Now let me briefly comment on our expected core operating income trajectory in 2018. The first quarter grew plus 4% in constant currencies. And we expect quarter two to grow low- mid-single digits as well. As I said, generally, we expect stronger core operating income growth in the second half, mainly due to increased contribution of innovative medicines' launches. On Slide 16, I would like to provide an update on financial items that should be helpful for you to model 2018. Most of this is related to the recently announced transactions. I have assumed that both the AveXis acquisition and OTC joint venture stake sale to GFK would close in the middle of this year. On AveXis, as I mentioned last Monday, we assume roughly $150 million or one core operating income point additional cost, mainly due to ongoing R&D programs, which would impact the core operating income line.

However, this is already considered in the full-year core operating guidance I just confirmed on the prior slide. Below the operating income line, we have three effects. First, the OTC joint venture is now classified as an asset head for sale on our balance sheet, hence the OTC joint venture will no longer provide income from associate companies as of April 2016. Second, for core net financial income, we expect approximately $50 million higher interest income from the investment of remaining cash proceeds after the expected AveXis acquisition. As a result, we expect our core net financial expenses to be approximately in the range of $780 to $800 million in 2018. Third, on core tax rates, we expect a slight increase versus 2017, but this is due to a mathematical effect as we have left income from associate companies. So, just as a reminder, income from associate companies is, as you know, always reported on an after-tax basis. Hence, by removing the OTC joint venture income, there is a mathematical increase in group tax rate.

There is however, no real impact on the underlaying business tax rate or the tax dollar amount we expect to pay. In summary, we would expect the two transactions together to dilute core EPS in 2018 and 2019 by about $0.20 in both years. Then the combined impact should be core EPS neutral in 2020 and strongly core EPS accretive from 2021 onwards driven by the significant ramp up of the AveXis sales on its way to an expected multibillion blockbuster [inaudible] effort. Of course, including the transactions, we would still expect 2018 core EPS to grow versus prior year in constant currencies and even more in US dollars. On slide 17, you see our currency impact guides for 2018. Assuming the currencies remain unchanged with the mid-April level, we expect for quarter two a positive currency impact of plus 4% on sales and plus 5% on core operating income. For the full-year, this positive currency impact remains plus 4% for both sales and core operating income.

And as you know, we continue to update our currency impact simulation each month on our website. And with that, I turn back to Vas.

Vas:

Great. Thank you, Harry. So, in closing, on slide 18, we started the year strong from an operational standpoint and financial standpoint. Our launch growth drivers continue to drive momentum powered by Cosentyx, Entresto, as well our oncology growth drivers. Our pipeline and key potential launches remain on track. And we're shaping Novartis, as you saw with our actions taken in Q1, as a focus medicines company. And we'll look forward to continued progress over the course of the year. With that, I'll open it up to questions. So, Operator, we can open the line.

Questions and Answers:

Operator

Ladies and gentlemen, if you would like to ask a question, please press *1 on your telephone keypads. If you change your mind and wish to withdraw your question, please press *2. You will be advised when to ask your question. The first question comes from the line of Michael Leuchten, calling from UBS. Please go ahead.

Michael Leuchten -- Barclays -- Executive Director Equity Research

Oh, thank you very much. It's Michael Leuchten from Barclays. A couple of questions please. No. 1, just clarification on your commentary around the Alcon margin please. So, is Q1 an unusually high margin now given some phasing? Or is the incremental margin step up from the [inaudible] OTC transfer? The main reason -- and I'm actually looking at this as a starting point despite the seasonality that we see through the year. So, that'd be question No. 1. Secondly, on Cosentyx, 1) Your NBRx share commentary in your slide is inconsistent with what one of the US company reported the other day. I just wondered whether you could comment on that, what the differences are and definitions? And they're talking about psoriasis shares. So, when you talk about your 17% NBRx share in dermatology, how do you think that compares to their statement? And then related, are you able to break down the inventory swings versus the rebate impact in Q1 for Cosentyx please?

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Great. Thank you, Michael. First on Alcon margin, Mike?

Michael Ball -- Chief Executive Officer of Alcon

Yeah, sure. So, the first thing is we don't forecast the margin for the year. But having said that, when you add the OTC business onto Alcon, that adds about three points of margin. So then, that restates 2017 to about a 17% margin. And what I've consistently said was 2017 is going to be the trough year for Alcon. So, you would expect margins to grow further from that. Now traditionally in Q1, our spending is lower than in other quarters. I would expect spending to ramp up in Q2. So, with respect to your comment around seasonality as it pertains to our spend, that would probably be true. As Vas said, as we look forward then out into the mid- and longer-term, obviously our goal is to get to the mid- to or at least low- to mid-20s in terms of operating income which is consistent with our peer group.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Great. Thanks, Mike. In terms of Cosentyx, Paul?

Paul Hudson -- Chief Executive Officer of Novartis Pharmaceuticals

Yeah. Thanks, Michael for the question. A couple of comments. I think I know what you're referring to in dermatology and psoriasis. I think it's important to understand that the IMS reported data is all I have in front of me and that we are a 17% share in psoriasis on NBRx. I think what you're referring to is actually a 6% from a competitor on NBRx. Perhaps some of the commentary from other calls has included a significant amount of free drug from a competitor which is perhaps even an internal calculation. So, we can't comment specifically on that. But if it was to be believed, then it would be a significant amount of free drug that's being given away to get to that number. We'll maybe get a chance later on in the call to give further background on Cosentyx, but we're very pleased with our underlaying performance.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

And then on the inventory stock and trade?

Paul Hudson -- Chief Executive Officer of Novartis Pharmaceuticals

So, on inventory, I know there's been a lot of comments already about Q1 over Q4. To remind everybody, we don't control the inventory levels and especially, pharmacy. And there was a destocking in Q1. For me, looking at the underlaying health of the business and why I'm comfortable with consensus this year is because we're already growing volume enough to offset the additional rebates to take a more impressive market position into the first line setting. So, the inventory accounts for most of the gap versus Q4, but the rebate that we've offset with volume is really the impressive start to the year.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Paul. Operator, we'll take the next question.

Operator

The next question comes from the line of Tim Anderson calling from Bernstein. Please go ahead.

Timothy Anderson -- Bernstein & Co. -- Managing Director, Equity Research, Global Pharmaceuticals

Yeah. Thank you. Can you just clarify on Cosentyx -- you're buying access to earlier lines of therapy. Can you just explain what that means, exactly? And then also on Cosentyx, you say in your press release that in most international markets it grew well. I'm wondering what markets were that it didn't grow well. And then why didn't it grow well there? And then last question on Cosentyx, head to head trial ongoing by J&J called Eclipse comparing your product to their IL23. And we've got results coming up in the back half of the year. And I can see that this is probably gonna be one of the things that investors are worried about next with the product. Can you give us your perspective on this trial, what you think it's likely to show, and how do you defend Cosentyx if Eclipse comes out in favor of J&J?

Paul Hudson -- Chief Executive Officer of Novartis Pharmaceuticals

Okay, Tim. Thanks for your questions. I'll often use the expression thoughtful rebating about how we approach things. There's many elements to that. One of them is being very considered about where we think the relationship between price and volume -- the volume can be accelerated. The other one -- and that's what's really interesting about our position in 2018 is we wanted to move deeper into more availability in the first line setting. I don't wanna overshare, but we've made low-double digit improvements, both in psoriasis, AS, and PsA to go into the first line setting, into effectively biologic naïve patients in terms of access while we've been predominantly competing in second line, we're now moving into that patient population, which is the majority just to remind everybody. So, we made a considered choice to do that which is really gonna open up the volume. And again, you're already seeing the volume improvements in Q1.

As for markets, we don't talk specifically. I'm enthusiastic that we're growing all geographies, all markets. Some a little bit slower because of reimbursement or biologic penetrations in general. We have no specific countries where I think we have a challenge. Again, our efficacy is really what's making the difference in the innovation in most markets. Some are slower of course, but they offer the whole class. In terms of the head to head, I think you described -- Vas, maybe you might wanna comment technically. All I would say to you is from a commercial perspective, it's clear that everybody thinks that we will be the significant player going forward.

So, they feel that they should need to do this. So, in some ways, we're flattered. But just to remind you again, we spent a lot of time separating out IL17 and IL23 in terms of indications that you can go into. And we feel uniquely differentiated as a class in PsA and AS. So, while we've maintained our position all along that we think psoriasis will be competitive -- and again, very pleased with our progress so far, despite new entrance -- that we still will remain the winner in AS and PsA. Vas?

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Yeah. Just on the study design, I think Tim, the important points are of course, this is -- to our understanding, primary endpoint is non-inferiority. So, that's I think indicative of a lot when you think about the study. And then of course, there are secondary endpoints that may look at superiority. I would also point out that in AS and PsA, as we look through the science at our investor day last fall, that there's very unique attributes to how Cosentyx works on the enthesitis or the insertion points into the joint, which clearly show in our view scientifically, medically, but also when you look at the data of the IL17-A class versus the IL12-23 class that IL17-A is the predominant upstream mechanism that really impacts the joints in the way you would want for both PsA and AS. And we think that will bear out over time. That's why we have such a strong NBRx already with Cosentyx in Rheumatology.

We're running head to head studies versus adadalimumab to demonstrate again, once and for all that we believe IL17-A is the right mechanism for those patients. And I would remind those on the call that the rheumatology market opportunity for Cosentyx equals that of the market opportunity in psoriasis. So, this is a significant opportunity that we're very focused on driving in addition to continuing to strengthen our position in psoriasis. So, Operator, we'll take the next question.

Operator

The next question comes from the line of Vincent Meunier calling from Morgan Stanley. Please go ahead.

Vincent Meunier -- Morgan Stanley & Co. -- Analyst

Hello. Thank you for taking my questions. The first one is on Kisqali. I mean, you say that it's off to a strong start and the next key events will be MONALEESA-3 and -7. But what can it bring really? Because so far, the challenge seems to be safety more than efficacy. And so, what should we expect actually from these MONALEESA trials? The second question is an update on the Advair generic CRL. Can you give more details and feedback from the FDA? Do you need to perform new clinical trials? And the last question is on Alcon, an update on the process. Might the sustained recovery of the units be a reason for you to wait a bit more before potentially divesting, or not at all? Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Vincent. So, I'll start with Kisqali, and I'll hand it over to Liz.

Liz Bennett -- Chief Executive Officer, Novartis Oncology

Thanks for the question. I think what we said was that quarter 1 was in line with where we expected it to be. The good news is we continue to see growth in both new and total patient share in the US. I think after obviously coming in just the last couple of months have been evaluating where we are, where we need to be, and I think we've done a lot of things right. And I also think we have a lot of opportunities for improvement, particularly around message and targeting. So, we've taken the opportunity to refine our messaging and our strategies against our targets and are rolling those out now in the US. And we feel very confident that they will have an impact on our patient penetration going forward. Importantly, we've also taken those key learnings and included those in all of our strategies as we roll out in Europe and the rest of the world where timing versus competition is really a lot closer or even sometimes at the same time, in some markets in Asia even ahead.

So, I think overall, we feel very good about it about where we are. To comment on the safety, I think you also have to think about it from keeping it in perspective as to what physicians are used to in this market and what our monitoring requirements are. And it's really a baseline and two time. So, I think there may be some perceptions. So, we wanna make sure that those perceptions are laid and that they're the reality of what exactly it is. And I think physician experience has been very positive so far.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

So, on the next question on Advair Gx on the CRL, we would expect to have to do a small bridging study, a biocolon bridging study, but we don't view this to be a significant hurdle from what we can see right now. So, our plan would be to get that study started and as I stated, to be ready for launch within 2019. And then on Alcon, we have always said that we wanted to be able to take a decision on Alcon from a position of strength, to really have the return of Alcon, which again, is the leading ophthalmology device company and contact lens company in our view in the world. And we see a continued strong trajectory. So, there's no real change in our outlook. We plan to have a potential action in the first half of 2019 if and when a decision is taken. So, there's no change in our perspective on that.

And Mike and the team are just continuing to focus on driving the business, continue to grow the topline, which you can really see now picking up, continuing smart margin expansion to enable us to get into the profitability range of our peers. And we'll keep you posted on our decision making process.

Vincent Meunier -- Morgan Stanley & Co. -- Analyst

Thank you.

Next question?

The next question comes from the line of Matthew Weston, calling from Credit Suisse. Please go ahead.

Matthew Weston -- Credit Suisse -- Managing Director, Pharmaceutical Research

Thank you very much. Some quick questions if I can. Paul, I'm sorry to come back to Cosentyx. And you probably won't be surprised by the question. But can you give us your experience in the first quarter of the year as to whether or not copay accumulator plans have had any impact on patient demand or your requirement to rebate the product and how those fit in given your confidence of the future growth? One for Richard. There have been some industry reports that Sandoz has supply issues on its biosimilar Rituximab. I wonder if you can comment and put those stories to bed. And then just a very quick one for Mike. I see that it notes stocking in the implantables business. There's been a lot of focus on Cosentyx destocking. Can you just quantify how much of the growth came from stocking within that marketplace? Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Matthew. So, first question Cosentyx. Paul?

Paul Hudson -- Chief Executive Officer of Novartis Pharmaceuticals

So, thank you, Matthew for the question. Maybe just an upfront comment about copay accumulators. I think we feel, like many others, quite strongly on this subject. And while every year there is a new initiative to try and extract further value somewhere in the chain, I think this is one we all feel passionate about because it's really against the interest of patients. So, disappointing that some patients may have to choose because of the way that this has been configured by the third parties. For us, the effect, if you're looking for the Cosentyx effect, it's negligible. It's very small numbers and frankly in line with the normal puts and takes through Q1. If this became a wider challenge, we would let you know for sure as we go forward through the year. But right now, with actions and measures taken, we don't see this as any reason to hamper the growth for Cosentyx. And maybe I could just add again, very pleased with the underlaying performance in Q1 in terms of volume, drive.

When you do provide more rebate to the system to access new patents, all you're looking for is a kick-up in volume to show that you've made the right choice. And the volume numbers really do speak for themselves. Over 60% growth versus Q1 last year in TRx, which is impressive. So, in case I forgot to mention it earlier, we are very comfortable with the full-year outlook and indeed, where consensus sits right now. Don't see copay accumulation as a challenge to that.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Paul. Richard on the supply for biosimilars?

Richard Francis ---- Chief Executive Officer of Sandoz

Yeah. Thank you for the question, Matthew. So, we're very pleased with the launch of our biosimilars across Europe that we rolled out last year. And the uptake in the willingness to prescribe has been very pleasing, particularly with Rixathon where I think, as I've mentioned in the past, the physicians have adopted it across all indications. So obviously, the penetration of biosimilars is moving very well. The success of Rixathon is looking very good. So, that means that in a way, we have a nice challenge. But what I would say around supply is that where we launched the product and where we've launched Rixathon, we have the ability to supply those markets and to grow those markets. And so, that's the way we manage it. But I wouldn't say we have supply issues. We more have how we manage the rollout of the product across the country that we're launching it.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Yeah. And maybe just one other comment on Biosimilars. I mean, we continue to believe we have the broadest portfolio in the industry. And we also continue to believe that given the environment in the US where there's clear commentary from the FDA commissioner, from the head of CMS in support of the broad use of biosimilars to remove cost from the US healthcare system and expand patient access that we're well positioned when those changes happen. And we believe those changes are going to happen because it's the right thing for the healthcare system, right thing for patients, and right thing for physicians. On Alcon, Mike?

Michael Ball -- Chief Executive Officer of Alcon

Yeah. So, on the question with respect to implantables, I assume the question is around the big growth we saw in implantables in this quarter. I think there's really four areas to look at here. In terms of stock and trade, it wasn't an increase in stock and trade in 2018. Rather, it was a reduction from last year in 2017 in the Asia marketplace. So, that has added some kick to that particular number. I should also remind you that the IOLs in Q1 in 2017 are rather low. So, it's a low comp as we're starting to turn that business.

As I look at the business and its performance right now, we've seen some nice stabilization in the monofocal IOLs but a really nice uptick in the advanced technology IOLs. So, I'm pleased with that because that's been one of our major focuses has been on PanOptix and restore. And finally, Zypass (sp) is in that particular group. As I said in the prior call, we're just getting reimbursement in the United States on Zypass, which is our mixed product. And it is starting to get traction then in the United States. So, it's really those four things that all combine for that result in implantables.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Mike. Operator, next question?

The next question comes from the line of Graham Parry calling from Bank of America. Please go ahead.

Graham Parry -- Bank of America Merrill Lynch -- Senior European Pharmaceuticals/Healthcare Equity Analyst

Great. Thanks for taking my questions. And apologies, Paul, but it is another Cosentyx one to start off with. Quarter on quarter prescriptions were flattening somewhat. So, you highlighted good growth in Q1. But there was only about 3% growth in TRx quarter on quarter. And to get to consensus for the year, which is around $3 billion is probably gonna require some sort of upward inflection in prescriptions in the US or ex-US to take up a lot more of the slack. So, could you just help us understand how you expect that to progress? Secondly, given the deals that you've been engaging in this year that have a dilutive impact below the operating income line impacting associates and their interest charges, is now the right time to start moving to EPS guidance for the market? And could you perhaps comment on how comfortable you are with the current consensus EPS level?

And then thirdly, on AveXis, you had said on the call that you discussed with the FDA data and felt comfortable with the data package. But do you have line of sight on FDAC on the AV9 vector specifically, given the Wilson papers target this vector and solid bioscience's clinical hold on its DMD trial which is also using an AAV9 vector? Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Yup. Thank you, Graham. So, first on Cosentyx, Paul?

Paul Hudson -- Chief Executive Officer of Novartis Pharmaceuticals

Yes. I took your point, Graham. I keep trying to repeat that while we transition through Q4 into Q1 and we're trying to make the right comparisons as we've converted free drug into commercial drug, I think the most useful comparison is the Q1 over Q1 last year and the overall TRx growth. Vas showed the charts a little bit earlier. They really are -- that NBRx number is really our leading indicator. And forecasting that forward, our own internal analysis puts us comfortably close to consensus. So, I'm very comfortable again with the underlaying prescription trends, both in Ns, Ts, indications, and geographies. Otherwise, it would be difficult for me to say that I was comfortable.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Paul. On EPS guidance, Harry?

Harry Kirsch -- Chief Financial Officer of Novartis

Yeah. Thank you, Graham. We don't intend to change the way we guide. I think by giving sales and core operating income in constant currency and ranges and then I would say a very specific guidance on the elements below core operating income and currency, I believe that what we have seen over the last years, that again, is community on the [inaudible] is very well able to model us quite well. Now of course, the changes are very recent, so we have to see how the overall consensus reflects this now, but I think with the comments I made today and last week, everybody should have very good information on how to model us, including the expected uptick of core EPS accretion in F of '20 for the AveXis deal and F of '21 for the combined deals.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Harry. Lastly on AveXis -- all questions related to AveXis regulatory findings need to be directed to AveXis. But what I can comment on is our assessment of AAV9 and the overall safety. So, important points to note about AAV9 and in general about the AAV space. So, AAV9 is the strain of vector we talk about. But then there's multiple variants within AAV9. And so, it's important to understand that there's different variants that we're talking about here. The second is that all of the findings that have been reported to date have been in animal studies and that these animal studies also vary from company to company. And based on animal studies that we've seen, and we've evaluated, we feel very comfortable with the profile. The third point is that risk benefit matters here. So, when you have a near 100% terminal illness and you have the opportunity to have a dramatic effect, regulators have a different view toward risk.

And importantly, in the reported studies in the New England Journal of Medicine, we saw no evidence of any of the dramatic toxicity findings seen in animals that Professor Wilson reported. We see none of that in the clinical data. In the paper, you can see there's transient liver enzyme elevations that resolve and then don't recur. And it's a single therapy, so we're not talking about a chronic therapy. So, once the transient elevations resolve, these elevations presumably will not come back. And the last point is dose. So, when you look at the dose, it's important to look at the doses that've been given in these different situations and important as well that in the SMA2 and in the older children that AveXis has publicly recorded in their clinical trials, they're using the intrathecal dose which is a small fraction.

So, when the risk benefit changes somewhat, you could argue -- though I would still argue it's still wildly in favor of treating -- that in SMA2, that you would still have a situation with an intrathecal does which is far lower than what the dose is that we're talking about in these animal studies. So, those are all these considerations that we had in our judgment that we don't feel that this a significant concern for us.

Graham Parry -- Bank of America Merrill Lynch -- Senior European Pharmaceuticals/Healthcare Equity Analyst

Operator

The next question comes from the line of Michael Comes from Michael Leacock calling from MainFirst. Please go ahead.

Michael Leacock -- MainFirst Group -- Pharmaceutical Equity Analyst

Oh, thank you very much. I have three questions if I may all relating to volume and price. In terms of the Cosentyx volume, and I do apologize for going back to this, when were rebates actually put in place? And how soon would it be reasonable to expect the change in prescription trends to be manifest? Secondly, you talk about this in the US, is there any risk or for that matter, opportunity, outside the US in terms of price versus volume adjustments? Are there any other products that might be suitable for a price volume adjustment if you truly believe that this delivers opportunity? And finally, on group level, we've seen a fairly stable volume price Gx, FX over the last few quarters with volume rising slightly. What are your expectations in terms of that volume growth rate in the longer-term? And what are the implications of your gross margin? Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

So, first Paul on Cosentyx in the US and EU.

Paul Hudson -- Chief Executive Officer of Novartis Pharmaceuticals

So, maybe the -- I think it's just worth reminding everybody that we include the rebates from pretty much the first of the year. That's how we calculate it. I think we have seen a volume improvement. Just to remind everybody again that our Q1 over Q4 minus inventory plus additional rebate has been offset by volume. And I don't wanna miss that point, just to be clear. And I didn't give Graham a full answer earlier of quarter on quarter growth rate. Inamburex (sp) was 12%. So, we're feeling we're nicely set up. I think ex-US, I think you also mentioned. We do see opportunities. In Germany, for example, we're market leader in biologic naïve patients in indications that we compete. And we're really making sure we're resourced appropriately to take these markets on. We're very pleased with our ex-US performance at the same time. I just maybe -- Vas, if it's OK just take a moment to clarify a question that was asked earlier around free drug and the liking things.

I just wanna remind everybody that our calculations include all drug free and commercial. The competitive comment which was one of the earlier questions that I got, the free drug I alluded to is absolutely in the competitive and not of -- when we aggregated up to on the NBRx performance. I just want to provide some clarity in case there was some people confused. Other opportunities on price volume?

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Yeah. I mean, I think in general, we're always and looking obviously to optimize our formulary position for all of our medicines and looking at how we do that through of course, the rebates and other important elements in terms of formulary positioning. And of course, we are watching the evolutions in the US market as well to be prepared for however the market evolves in terms of how the structure of the insurance and rebate environment changes, given all of the focus on this. And then in terms of group volume growth, Harry?

Harry Kirsch -- Chief Financial Officer of Novartis

Yeah. I think your question, Mike toward the end, how do we expect the cross margin to develop. One element is of course, price volume. Overall, we expect the growth margin to develop positively this year but also over the next years. One element of that is that more high value medicines will become part of the mix, No. 1. The second one is that we have -- at least when you look at August '19 -- the expected LOE on GILENYA, we have royalty on it. And the products that we placed is more than we placed from our expectation don't have royalty or just low manufacturing royalties or positive royalty mix. And thirdly, the significant manufacturing network transformation that we are driving forward will increase capacity utilization and reduce also production costs. So, while these things happen over time, I'm quite positive on a positive cross margin development over the next years.

The next question comes from the line of Florent Cespedes calling from Société Générale. Please go ahead.

Florent Cespedes -- Société Générale SA -- Senior Sell-Side Equity Analyst

[inaudible] Thank you so much for taking my questions. Quick, quick ones. First for Paul, on Entresto, it seems that there is an inflection point. So, it may be early days, but do you know if it could be attributable to your new marketing message on quality of life that resonates within the medical community? Or is there anything else? Second product-related question again for Paul on GILENYA. Could we add a little bit more color on the performance in the US and in Europe of the product within the multiple skill base and what is the proportion of the US performance which is driven by the stocking effect? And last question for Liz is carried from Vincent's previous question. Liz, could you be a little bit more specific on the when this new message, new target that you will have for the product? Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Florent. And thank you for the question on Entresto. Paul, I think is quite excited to answer. So, Paul on Entresto?

Paul Hudson -- Chief Executive Officer of Novartis Pharmaceuticals

I'm very excited, Florent. And I think I attribute it to what is a trend break based on great marketing capabilities and our communication of the quality of life data. It is nice to get a question on Entresto. We work incredibly hard in this area. The news flow in Entresto while everybody is of course rightly looking forward to preserved ejection fraction, the actual news flow through the last few months and into this year is really staggering when you think about the quality of life data. In fact, the quality of life data is probably one of the single biggest generators of interest for this specific patient population. And when we get great anecdotal feedback from patients and indeed, partners of patients, it is always about feeling that difference. So, that's very reinforcing for the prescriber to go after depth because they haven't had that opportunity before.

So, the news flow only strengthens this year, and we have to applaud the team and the comments we made '16 and earlier, really on this level of data. As for trend break, we've tried to guide all along that we know, in fact, that Entresto will be accretive from the very first day of 2019 -- we're really nicely set up -- and that our performance this year is really trending toward a large number. And I think it just vindicates the work put in by everybody and the commitment. As for GILENYA, what went against us a little bit on inventory movements, especially pharmacy with Cosentyx went for us a little bit with GILENYA. So, the US performance was increased in terms of dollars by -- in the majority, I should add -- an inventory improvement and a little bit on price. What's really important to remember -- and I don't want this to get lost in the conversation -- the underlaying health of the business in the US both on TRx, NBRx, and indeed, what we see on the SRx, the patients that are lining up to start is very strong, irrespective of new entrants.

So, it's important to have that confidence as we run through this year. But our Ts are slightly ahead perhaps where we expected given the level of new entrants. So, we're delighted all around. The other important point, and you raised it in terms of ex-US -- let's also be clear. We have a patent that runs through to I think March '22 and a share around about 20% stable and, in fact growing in some markets. So, it's important to separate those two conversations, as you know because that's a very big time difference. But healthy business in the US, a little bit bought by elementary movement in Q1 but underlined very strong.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Paul. And then on Kisqali, Liz?

Liz Bennett -- Chief Executive Officer, Novartis Oncology

Yeah. My first thought was I don't wanna share too much because from a competitive standpoint. But I think the most important thing to focus on is that we will be focused on growing the market. The CDK market is a large market. If you look at the penetration of the CDKs, it's only about 50% in first line and about 40% overall. So, there's a lot of room and a lot of patient segments and populations that can still benefit from these treatments. The important thing for us is for us to be the first CDK used and to use in first line. So, that's where our message will be focused, on ensuring that we are the first CDK used for Kisqali. So, that's really where we're focused and making sure that we're growing the market and focused on gaining those first line patients. The good news is is when you look at our share, and as you've seen over the last couple of months, is that we are stronger in first line and see an increased penetration in that market. So, that's been our focus, and that will be our focus going forward. So, thank you.

Florent Cespedes -- Société Générale SA -- Senior Sell-Side Equity Analyst

The next question comes from the line of Steve Scala calling from Cowen. Please go ahead.

Steve Scala -- Cowen and Co. LLC. -- Senior Research Analyst

Thank you. I have several questions. First, you provided a lot of helpful commentary on Cosentyx. But I'm wondering on the magnitude of the destock, it looks like it was about $30 million. So, maybe you can comment on that. And the magnitude of the enhanced rebates. Were they roughly an incremental 15%? Questions for Liz Barrett, you did a great job building eye brands but perhaps too good because the franchise now looks impenetrable. What are the weaknesses of eye brands that you can now exploit? And do you agree that MONARCH-3 has established Verzenio as delivering the best performance in first line disease? And then lastly, why won't Russia's CD79 bispecific [inaudible] lower the opportunity for CAR-T and DLBCL? Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Steve. So, first Paul on Cosentyx?

Paul Hudson -- Chief Executive Officer of Novartis Pharmaceuticals

Yeah, Steve. So, it's good to clarify because we really do need to clarify these things because I'm again, excited about our underlaying performance. In fact, we're exactly if not slightly better than where we predicted on demand at this point. So, it's worth reinforcing. And I really don't mind how many questions we get to support this because again, we feel very good where we're at. I chose the words 'the majority.' We can be more specific, but there is some competitive elements to how these variances are made up. So, I think I'll stick with the majority of the quarter over quarter change was due to inventory. As for rebates, same applies really. We did improve rebates.

But I won't share the exact percentage. But please don't underestimate what it meant to get low-double digit improvements in unrestricted access in the first line setting. There's one thing rebating to maintain a position the market with new entrants. There's a very different thing rebating to expand the available patient population and compete in the big pool. And to have got back to roughly the right sales number by volume given increased rebates, we know we've made the right choice.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Paul. On the CDK46 market, that's Liz.

Liz Bennett -- Chief Executive Officer, Novartis Oncology

Sure. Thanks for the message. I think that I'm not gonna comment obviously on eye brands. But I do think that, as we've talked about before, this is a large market. It's a large market, and it's gonna grow over time. It's gonna penetrate in the metastatic setting and then hopefully eventually move to the adjuvant setting. And we expect to be a formidable player in that market. We think there's room. The addition of now three CDKs in the market will continue to grow the market. And I think that's the most important thing. One of the things that we've seen if you look a t it from a market perspective is that there are still patient populations that aren't seeing a CDK. And I think if you look at the clinical data across all of the competitors, and particularly in Kisqali. you'll see that every patient population can benefit from Kisqali and the addition of Kisqali. And I think that's where we have to focus on is increasing penetration in the market. As we said, it's a big market, and there's an opportunity.

And we believe that will continue to be able to be an important, relevant medicine in this market. As far as MONARCH, I'm not gonna comment too much because they're not obviously, head to head studies. But what I will say is that if you look at the inclusion criteria of the different trials, they're different. And so, I think it's very difficult to make comparisons. I think you need to look at the hazard ratio and look at the patient populations in which they're all studied, which is like I said, slightly different across the board. And I think there was a third question.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Yeah. Maybe just one additional comment on CDK46 and Kisqali. I mean, one of the striking things as I've toured the markets, particularly in many of the European markets, is our long legacy in breast cancer. I mean, we know the breast cancer community. We have experience because of Femara, Zometa. I mean, we've been with these physicians for a long time. We are not a new entrant in breast cancer. And that gives us a strong commercial position then to launch a new medicine. So, I think that's gonna help us as we are much more comparable in some of the European markets. On the last topic, on the bispecifics versus CAR-T therapy, I think the critical thing here is durability. I mean, we know that with Kymriah and pediatric ALL, we see durability up to five years in many of the patients. In DLBCL, we're following. But we know patients who get to six months usually stay in a response up to 12 months and then longer-term.

I think the open question with bispecifics and some of the other technologies is can they lead to a durable response because with these patients, what you're looking for is a durable response to give them back their lives. So, that's gonna be the open question. I don't know the answer. But we do know that CAR-T cells, because of the ability for the T cell clones to expand again when the cancer recurs, when you do have patients who have that long-term response, they tend to stay in a positive state. So, that's how we think about the threat of bispecifics and other technologies versus CAR-T cells. Operator, next question?

The next question comes from the line of Tim Race calling from Deutsche Bank. Please go ahead.

Tim Race -- Deutsche Bank -- Pharmaceutical Analyst

Hi there, team. Yes, it's Tim here. So, a question on Cosentyx, sorry. Basically, this destock. Can you just confirm that it is actually a destock from normal levels to lower stocking levels, so we should expect a restock in second quarter? Or is it that stock levels were too high before and they've come down? That'd be the first thing. And then secondly, maybe just talking about acquisition strategy. You made a big point in much of your communication, Vas, since you've become CEO to talk about digital and data. Could you just help us understand your tangible financial targets that you have behind this and whether we should see you making acquisitions in this space as well to further optimize and enhance your portfolio? Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Great. So, I think on the destock, I mean, just to show you how deeply we've looked at the -- I'll actually have Harry comment because Harry's actually looked at the numbers in detail. Harry?

Harry Kirsch -- Chief Financial Officer of Novartis

Yeah. Of course, Tim. Thank you for the question. As you know, we are very diligent every month and every quarter and especially yearend that we ship in line with demand. Of course, not every little million, so to say, is part of our control. But overall, what we have seen here in Cosentyx, very normal inventory levels, especially in the US. Of course, there's especially pharmacies, so we don't control everything to the last dollar. But we had in quarter four very normal inventory level as we had throughout the last couple of years. And this is a destocking from a normal level. Now we do not count on it coming back because still OK level. But the normal levels have been higher over the last two years.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

So, on the digital front, we look at this over time. And this is more of a medium to long-term impact, transforming the efficiency of our operation from a research development and commercial standpoint and then hopefully also leading to new therapeutics and new innovation, more things like Pear Therapeutics, the two deals we've announced in the quarter. So, we do look externally now to make significant partnerships and investments. I think you'll hear more and more from that building off of the things we've already done in Q1. I think it's too premature to give it a hard financial number other than to say that when we look at how other industries have used these technologies to improve productivity and drive margin expansion and also to improve the overall efficiency of the operation, it's quite significant. And we would like to be a leader in our industry in doing that, which is why we have Betrand on the team and continue to do the work that we've already set forth.

I think more uncertain is how digital therapeutics will unfold. But we're the first company now to take a digital therapeutic forward in Pear, and we're gonna learn a lot about how this unfolds. And it could end up being quite significant. If you look at some of the news flow on things like Omada Health and some of the other companies out there that have had quite an impact on patient outcomes by using digital technologies -- here with Pear Therapeutics, you have a technology that actually has an FDA label for addiction therapy. And so, we're gonna take this to launch, and we're gonna learn a lot. And then it could lead to a whole new business line, to be seen. But I think the only way we're gonna win in this space and transform our business is to start to get out there and make partnerships with some of the leading companies. And that's what we're setting up to do. Next question, Operator?

Operator

The next question comes from the line of Richard Vosser calling from JP Morgan. Please go ahead.

Richard Vosser -- JPMorgan Securities Plc. -- Research Analyst

Hi. Thanks for taking my questions. Vas, you eluded to changes in the US market, and I think we've got a communication from President Trump coming up in the next week or so. So just, what's your thoughts for that communication? What could change for the industry and specifically around Novartis? Second question, just on Sandostatin LAR Clearly no patents left in the US, but should we be thinking about a generic in 2018 or 2019? And then finally, just on Sandoz and pricing pressure, clearly significant pricing pressure in this quarter. Could you give us an idea of the level and how you expect that level to continue throughout the rest of 2018? Thanks very much.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Yeah. Thanks for the question. In my time so far in visiting Washington, D.C. multiple times and being in the various discussions including participating in the dinner with the president, my overall expectation, as well I would say conversations with the FDA commissioner and hearing his perspective as well as the CMS administrator, I think there's a few areas of focus. And I don't think they're new. I think there's gonna be a continued focus on Part B and reforming Part B and taking out some of the incentives for your excess utilization in Part B. And I think that's very real. That could happen. I think 340B and reform of the 340B and how 340B may create distortions in the use of Medicaid hospitals -- I think that's another area that's gonna be in focus. Continuing to enable biosimilars and competition in the marketplace is a huge interest to the administration. You've seen them take actions both at CMS and the commentary of the FDA commissioner.

I think that's gonna be clearly in focus. Ensuring that generic companies have the ability to enter at the appropriate time with appropriate access to samples in order to do their studies again, is gonna be an area of focus. And I would say another big theme is gonna be trying to increase transparency in terms of how does the money flow, what is actually getting to the patient, and what is getting pocketed in between the pharmaceutical company and the patient. There's a huge interest to try to -- that's the toughest one, but that's also I think a huge area of interest. Now in general, I take a longer-term view on this. I think we have to be part of a sustainable solution for the healthcare system. We have to find ways to make this sustainable, so we as a company can succeed. When you look at any one of these, and even when you look at the recent action on the Part D donut hole, these have limited impact on Novartis given our portfolio and overall profile.

We don't have many Part D medicines. We're not exposed to biosimilars risk. We have limited medicines that were really impacted by the donut hole action in the recent budget round. So, we view our exposure as low, but I more view our role as being a positive force to try to shape this environment so that it's a sustainable environment and destructive actions aren't taken that would impact our industry and impact innovation. Now on Sandostatin LAR, Liz?

Liz Bennett -- Chief Executive Officer, Novartis Oncology

Yeah, sure. I think the important thing on Sandostatin is we've had good results. We're flat, even despite competition in this area. But when you talk about generics or other entrants, the most important thing to think about is the complexity of the manufacturing. So, many have tried in the past unsuccessfully to enter this market. And it's really driven by the manufacturing complexity. So, while we do and always looking at potential risks from generics and the competition in the future, we know ourselves with our own experience how difficult it is to make. And I think that the quality of the manufacturing is gonna be a deciding factor on anybody's ability to get in. I can tell you that we are not projecting in 2018 there to be any competition from generics. As we move into 2019 and beyond, it will depend on again, the ability of other manufacturers. But I don't think that anyone is gonna be able to supply globally the way that we have been able to do in Novartis because of our expertise in this area.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Liz. Thank you, Richard. Oh, did we have another question?

Richard Francis ---- Chief Executive Officer of Sandoz

Yes, we did.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Oh, sorry. Richard?

Richard Francis ---- Chief Executive Officer of Sandoz

Thanks for the question, Richard. So, we don't actually break out the pricing number for the US. So, apologies for that. But to give you my view on going forward, I don't actually see a significant change in the pricing pressure in the US. And I'll give you some reasons for that. One is the channel is too consolidated, and there's huge pressure on the channel to drive their margins. And so, they're obviously pushing that pressure back onto the manufacturers. The second is competition continues to rise while the FDA approvals continue to come through and companies continue to enter the US market. So, I think that's the reason why I don't see significant change. Now obviously, pricing can fluctuate just based on poor dynamics and competition. What I would say is our focus is on changing our portfolio and making sure we drive to a more differentiated portfolio.

And as you know, we're gonna be -- we got the biosimilars coming through to the US market, and we're very confident about bringing two big products to the US market in a short period of time and also moving our products toward a more differentiated portfolio where obviously, there'll be less competition. So, I think that's another thing to bear in mind. And that's a strategy we've been executing for some time. Now I will close -- and apologies for the long answer -- with when you look at our number in the US and the decline of 18%, there are a couple of factors within that that go beyond price.

One of those is pruning and divestment of our portfolio, which we've been doing over a couple of years. Going back to what I said about reshaping our portfolio, that's the action you see there. And that has an impact on the Q1 numbers. And the second thing is there has been a fluctuation in [inaudible] which has also hit Q1 as well. So, hopefully that helps give my perspective, Richard and answers the question. Thank you.

Richard Vosser -- JPMorgan Securities Plc. -- Research Analyst

Thanks.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Great. Operator, next question?

Operator

The next question comes from Dhanya Nair calling from Goldman Sachs. Please go ahead.

Keyur Parekh -- Goldman Sachs -- Analyst

Hi. It's actually Keyur Parekh here. A couple of questions please. Vas, you talk about Novartis being a more focused company. Can you expand a bit more on that? Where do you see that? Do you see the actions you've done year to date as being in the early innings of that focus? Do you think you are becoming -- you are there, or you want to be? What should we expect over the next 18-24 months from a big picture perspective? And secondly, obviously very strong from an oncology perspective. Big heritage there. But still a lot of questions about the roll you guys might play in the immune-oncology market going forward. Based on what you've learned at ACR, does that change your perception of Novartis' position there? Where do you think you guys might end up playing in that market? Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Yeah. Thank you. On the actions, I think it's always evolving, of course. But we have a -- we started out and we of course have a position in consumer health. We have the position in medical devices and ophthalmic devices. We have our generics business. We have our innovative medicines business. So, we've taken action now on the OTC. We've stated we're under an active evaluation and preparations with respect to Alcon. In Sandoz, we have also stated that we're continuing to evaluate the portfolio in the US. We have a strong business in the US and a strong commitment to the US. So, we're evaluating our best approach, especially with respect to certain segments in the US. And that will continue. And then in parallel to that, we also want to continue to focus our capital and build our innovative medicines business, which what we did already with the AveXis transaction. And we'll continue to look at bolt-on on MNA.

Our capital allocation priorities remain focused and invest in our business. We believe we have one of the best pipelines in the industry. We have the 13 potential blockbuster launches coming. We have a world class R&D engine. Second, strong and growing dividend. That does not change. And third, to use our capital to find strong bolt-ons that continue to build up our business in our core therapeutic areas and also bring new platforms like gene therapy or like radionuclide therapy into the company or even digital therapeutics. And then lastly, when appropriate, to share buybacks as we've always done. We've always offset the employee share programs, and we'll continue to evaluate appropriate share buybacks as well over time. And that doesn't change either.

And those capital allocation priorities are clear. But I think the big shift now is focusing the capital in the places that generate the highest return and the highest impact that we have in line with our overall ambitions as a company. Now when I look at the oncology situation, and I know of course a lot happened, I think there's very impressive data, certainly from the PD1 from one of our competitors, which I think is transformative for patients with lung cancer. So, it's a great thing in general for society and for patients. I think we have to of course have pause now about second generation IO. We evaluate our second generation assets now at a higher bar. We increasingly wanna ensure that we have appropriate control arms so that we can see whether or not the combination is having an impact on top of the PD1 mono.

And I think one of the things we're also putting a very heavy lens on is do we have single-agent activity? Because I think single-agent activity will increase the likelihood that whether in combination or not, we might have a medicine that's gonna matter. So, it is making us I think of course, revaluate and have a higher bar on what we progress. The nice thing for us in oncology is we have a broad set of platforms. We are a leader in targeted therapy. You see that in Mekinist and Tafinlar as well as a leader in non-malignant hematology as you see with Promacta, Revolade, Exjade, and Jakavi. So, we have that strong position. Second, we are a leader in CAR-T. We have Kymriah. We have a broad portfolio of CAR-Ts coming behind that. So, we have that as a platform. We have immune-oncology.

We have the 20 or so assets that are in the clinic evaluating them, but we'll take a stronger look at them. And then we brought in radionuclide therapy, transformative and neuroendocrine tumors. We'll see how it unfolds in prostate cancer. Also looking at gastric cancers. So, we strategically trying to take a broad position, so we're not overexposed to IO per se, and it's not a binary event for us whether IO pans out for the company.

Liz Bennett -- Chief Executive Officer, Novartis Oncology

Okay. I'm just gonna make one more comment about IO. And I think that one of the other learnings we're having is in IO in combination with targeted therapies. So, if you look at the TafMek plus our own PDR that we're studying today and some of the other IOs in combination, I think that's also an area that we will continue to interrogate, an opportunity.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

And we see Mekinist, Tafinlar, plus PD1 is a very exciting opportunity for us given our leading position in BRAF mutant cancers. So, next question --

Keyur Parekh -- Goldman Sachs -- Analyst

Just a follow-up then. When do we see data on this program next?

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

We're all looking at each other. We'll come back to you with a precise answer. I don't wanna say something incorrect.

Keyur Parekh -- Goldman Sachs -- Analyst

Sure. Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Yup. Next question?

Operator

The next question comes from the line of Eric Le Berrigaud calling from Bryan, Garnier. Please go ahead.

Eric Le Berrigaud -- Brian, Garnier, and co. -- Sell Side Equity Analyst

Yes. Good afternoon. Four quick questions please. First, to come back Harry's comment about the $0.20 dilutions coming from the two recent transactions. Could we understand that this is going to go through the P and L or do you intend to mitigate that, at least in part, that dilution? Secondly, also coming back to a previous comment about supply for Rixathon. The understanding is that you can supply in markets where the drug is already launched. How should we interpret that in light of the upcoming US approval at the end of the year? Should we expect additional supply capacity by then or meaningful delay between approval and launch in the US?

Third, on Aimovig as we come close to the approval, could you maybe just remind us how it's gonna play out for US in your accounts, whether there is any sales or only part of profits booked in other revenues or any other way to book that in UPNL? And fourth and last question, you put a voucher back in December, and I guess you probably got another one from Kymriah early on. Could we ask maybe what you intend to do with those voucher, or if it's fair to assume that at least one of the two filings, [inaudible] this year will benefit from one or the two of them? Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Ryan, so first, on dilution, Harry?

Harry Kirsch -- Chief Financial Officer of Novartis

Yup, Ryan. So, the $0.20 I mentioned, the majority of that is from not having the OTC joint venture income from associate companies as of April. It's roughly three quarters of it, $0.15. $0.05 is from the roughly ongoing trials agitating inclusion after expected the closure from the AveXis acquisition. But that's within our core operating income guidance. So, those are the two elements on the dilution.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Great. Thank you, Harry. On Rixathon supply, Richard?

Richard Francis ---- Chief Executive Officer of Sandoz

Yes. Thanks for the question. And [inaudible] clarity. So, we are all set for a US launch. So, from a supply point of view, we obviously targeted and prioritized the US market to make sure that was possible. So, that is the case. And maybe to clarify what I said in the past. We are in a position to supply the markets we've launched into as we see increase in demand and interest. And we obviously prioritize the markets we move into after that. And as we go into them, we make sure we have enough supply. And finally, I'd like to say -- and I didn't earlier -- but we are building capacity at the same time. So, in parallel, as we see this high level of interest in biosimilars and Rixathon as well, we're building more capacity within the Novartis network.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Great. Thank you, Richard. On Aimovig's financials, Harry, in the US?

Harry Kirsch -- Chief Financial Officer of Novartis

Yeah. In the US, as you can see also in our press release when we announced the deal, we have major co-commercialization where we do not book the sales, but we get a -- so, [inaudible] would book the sales. We get a royalty which you will see coming into our P and L as other revenues.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

And then lastly on priority review vouchers, you are correct. We have multiple priority reviewed vouchers. Given the strength of our pipeline, we think it's prudent to have multiple priority review vouchers to enable us to accelerate programs. We'll comment on which priority vouchers we've used on which programs when we've received acceptance of the file from FDA and their confirmation of the priority review. So, you'll be hearing more from us over the course of this year. So, we have five minutes left. I'd ask the next couple of questions, you could keep them quick, so we can try to get through everybody's questions. But Operator, let's go to the next question.

Operator

The next question comes from the line of Emmanuel Papadakais calling from Barclays

Emmanuel Papadakis -- Barclays -- Analyst

Thank you for taking the question. I'll try and keep them quick. There was a quick follow-up on Rituximab at US timing. I think the previous question cited end of the year. By my math, should be more like July. Haven't seen any sign of an adcom yet. Maybe you could just comment on timing and expected uptake in volume terms relative to what we've seen in Europe where you have launched. And the second quick question if you could answer it is just a bit more color on Kymriah. The uptake you gave a helpful sales figure. You said the majority lays in Alcon. Maybe you could talk a bit about patient centers' trajectory you expect for the rest of this year. Thanks very much.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Yeah. So, quickly on Rituximab, there is no planned adcom right now. We've got confirmation from FDA that won't be case. In terms of commercial uptick, Richard?

Richard Francis ---- Chief Executive Officer of Sandoz

Yeah. We're very positive. A lot of it depends on obviously timing and when we actually get the full approval and when we actually work through if there are any issues around litigation. But what we're seeing right now is a high level of interest. I think the US market has started to see what's happened in Europe. And so, that's really helped generate more enthusiasm. And also, obviously it's a small community, so they're speaking to each other. So, I think it's timing. What I would say, timing is something which is hard to predict. I'm pretty sure it's gonna be this year. And then we'll see exactly when it is. But with regard to uptake, enthusiasm's high. And we'll obviously get out there. And we don't give forward guidance on sales. I wanna stick to that. And we'll let you know as of when we launch and keep you updated as of when the launch progresses.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Great. And on Kymriah, Liz?

Liz Bennett -- Chief Executive Officer, Novartis Oncology

Yeah, sure. I'd love to give a little bit more color on that. As we've talked about before, the revenue in Q1 was actually in line with our expectations. We have been focused on exactly what you're talking about, expanding the sites. We now have 35 sites up and running. Just keep in mind, it's a new therapy. It's a new therapy for us, but it's also a new therapy for the hospitals and centers. So, we spent a lot of time making sure that the experience that they're having is a positive one and that we're getting the logistics down properly and we feel very good about where we are and preparation for the DLBCL hopeful anticipation of expansion soon.

So, I think we feel that reimbursement, we have not had any issues with reimbursement. That's going very smoothly. The sites are up and running. We feel very good about that. And in anticipation again of the expansion of the label soon. So, I think so far so good. Yes, we expect that we'll see the trajectory improve over time. But again, keeping in mind not only with ALL, but also with as DLBCL starts to launch, that these patients need to be referred to the centers. So, I think you'll see a continuous improvement quarter over quarter. But it will take time for these centers to get up and running and used to using this new therapy.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Next question, Operator?

The next question comes from the line of Louisa Hector calling from Exane. Please go ahead.

Luisa Hector -- Exane -- Pharma Research Analyst

Hi. Thank you for taking my question. So, on Cosentyx, I would like to ask whether your infrastructure selling efforts is sufficient or needs to be expanded, so that you can make sure you take full advantage of the increased access and the rebates? And could you comment on the duration of contract? Have you locked these rebates in for one year or possibly for longer? And then finally, in the FCC documents for AveXis, their internal forecasts seem to show a revenue stepdown in 2026. I just wondered if there was something specific going there that you could comment on please. Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Yeah. So, Paul on Cosentyx?

Paul Hudson -- Chief Executive Officer of Novartis Pharmaceuticals

Yeah. Very good question, actually. Perhaps we haven't shared this widely. But over the last six and 12 months we have built field capacity to fully maximize each indication. In fact, we separated -- it's not a secret. We separated our sales forces to align between each of the three major indications. So, we wanted that level of accountability and specific focus. No different in the US. We don't need to add any more resource in the US for Cosentyx other than some small opportunistic investments.

We are absolutely perfectly deployed because we covered these same positions, rheumatologists, dermatologists with the right frequency to be able to be front of center for this first line patient which we'll be focusing a lot on. The duration of contracts, we have worked very hard also to make sure that we are a long-term partner of the major players. We think in multiple years, it's not always easy to achieve that. But of course, when you add additional rebate to the system, you run a business case that allows for short and long-term returns. We're very careful with how we do it. It's a long-term partnership. I wouldn't wanna give away more specifics than that.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer

Thank you, Paul. On AveXis, I can't obviously comment on their forecasts. But I can tell you how we look at this. I mean, we look at this as an opportunity first in SMA1 expanding to SMA2 and importantly, the prevalent pool of patients which we view as sizable, and we also view this therapy as the first line therapy choice for these patients given it's a transformative efficacy that we've seen thus far in the clinical trial.

Now as the prevalent pool then gets penetrated through, you peak the sales, and then come back to the incident population over time where, as I presented as well, newborn screening and our expectations around that would allow as the deal closes, and us to take forward the medicine to have a consistent then, sales base over time. So, the key is how you model that prevalent pool. We have a perspective on that. But I think that's what you see when you see that big bulge in the sales curves.

Luisa Hector -- Exane -- Pharma Research Analyst

Thank you.

Vasant Narasimhan -- Global Head Drug Development and Chief Medical Officer
