Thank you, operator. Good afternoon or good morning, everyone. I'm delighted to welcome you to our H1 results presentation. As you just heard, I'm David Loew, Chief Executive Officer of Ipsen and it's a pleasure to take you through our performance in the first half of the year. Note that our presentation is available on ipsen.com. Please turn to Slide 2. This is our safe harbor statement, which outlines the routine risks and uncertainties contained within this presentation. Also any commentary on growth you'll hear today will be based on constant exchange rates, unless stated otherwise. Please turn to Slide 3. For the presentation and for the Q&A, I'm joined today by our CFO, Aymeric Le Chatelier. Please turn to Slide 4. Here is the agenda for today's call. I will start the presentation with an overview of the business, after which Aymeric will take you through our financial performance as well as our upgraded 2023 guidance. After concluding our presentation, we'll be happy to take your questions. Please turn to Slide 5. So let's begin with the business overview. Please turn to Slide 6. Today's headlines illustrate how we are continuing to deliver on the strategic roadmap. In the first half, we produced a total sales increase of 7.4%. Our growth platforms, again delivered a double-digit performance led by Dysport and Cabometyx. These growth platforms along with our newly acquired medicines now represent around 2/3 of our top line. In the first half, we also delivered a solid core operating margin of 34%. We completed the acquisition of Albireo at the beginning of March, and the integration is progressing well. On the pipeline, it was a product this previous filing of the Onivyde sNDA in first-line Pancreatic ductal adenocarcinoma was accepted by the FDA, which also approved Bylvay in its second indication, Alagille syndrome. There was a favorable outcome from the FDA's Advisory Committee meeting regarding Palovarotene in FOP. While at the end of June, we announced that the primary endpoint was met in elafibranor Phase III relative trial in second-line primary delivery cholangitis. Finally, given Ipsen's performance in the first half, we are today upgrading our full year guidance on both total sales and the core operating margin. We now anticipate total sales growth greater than 6 in 2023, along with the core operating margin of over 30%. Please turn to Slide 7. Our growth platforms are continuing to excel, outlying the gradual decline of Somatuline. In the first half of the year, they grew by 18%, led by strong performances from Dysport and Cabometyx. Our newly acquired medicines also delivered meaningful contributions with Bylvay to stand out. Somatuline now at around 1/3 of total sales continues to decline gradually in line with expectations. I'll now take you through our sales performance in more details. Please turn to Slide 8. Looking at our growth platforms in more detail, Dysport's momentum continues. Growth of 32% in the first half reflected a strong aesthetics performance by both Ipsen and our partner as well as continued strong double-digit performance in therapeutics. As you know, there was a favorable supply comparison to that in H1 last year. We anticipate the opposite dynamic in the second half. Cabometyx sales up by 26% were supported by strong volumes in Europe and the rest of the world despite adverse price impact, mainly in Germany. The growing contribution from the first-line renal cell carcinoma combination with nivolumab continued, including the recent launch in Italy, where we have already achieved strong levels of total patient share. The Cabo/Nivo combination is now reimbursed in over 20 markets. Decapeptyl grew in the first half by 6%. There was a particularly strong results in Q2, especially in rest of world with China exiting the impacts of COVID. Growth in Europe was more subdued in the first half, however, partially impacted by adverse pricing. Finally, Onivyde continued to deliver strong underlying growth in the U.S. North America sales increased by 19% in the first half as we continue to make market share gains under the current label. We're now accelerating our prelaunch activities ahead of the regulatory decision in first-line PDAC in the new year. Please turn to Slide 9. Somatuline sales fell by 12% in the first half. This was further evidence of its gradual long-term decline profile as illustrated by the chart, you can see. In North America, sales fell by 10% in the first half. Volume demand and the market remained in solid growth, but pricing continues to be impacted by the level of commercial rebates and adverse movements in channel mix driven by the increased effect of 340B. Europe, where sales declined by 22%, now presents less than 1/3 of Somatuline sales. Here, the volume and pricing impact from generic competition continues, though we do anticipate a slightly sharper lower decline in Europe in the second half of the year given the baseline effect. Finally, in the rest of the world, solid underlying growth continued with several geographies performing well, including Latin America. Please turn to Slide 10. Turning to our recently acquired Epizyme's Bylvay has delivered a strong performance since we acquired Albireo at the beginning of March. Growth of 140% year-on-year reflected momentum in both North America and Europe, and we continue to see an increasing number of patients treated for PFIC. Sales of Tazverik amounted to EUR 19 million in the first half with commercial sales up by 18% year-on-year. As you know, relaunching a medicine takes time. sales in the U.S. will, therefore, see a gradual increase as we are repositioning the medicine in all comers and for elderly unfit patients in the office-based setting, which has not been the case before, and where we now see increasing sales. Please turn to Slide 11. Turning now to the major elements of our pipeline. There were a number of favorable developments in the first half of the year. Firstly, the FDA accepted the filing of Onivyde, NALIRIFOX regimen in first-line PDAC and approved Bylvay for the treatment of cholestatic pruritus in patients from 12 months of age with Alagille syndrome. The FDA's Endocrinology and Metabolic Drugs Advisory Committee also voted in favor of palovarotene as an effective treatment for people living with FOP. Positive top line data from the pivotal Phase III trial of elafibranor in second-line primary biliary cholangitis were published at the end of last month. The trial met its primary endpoint and full data from the trial will be presented in due course. Finally, we plan to add more patients to the Phase III Bylvay BOLD trial in biliary atresia to maximize the probability of success. We estimate a readout in around 2026. Please turn to Slide 12. We have plenty more pipeline news following in the coming months, including several potential regulatory approvals. Following the outcome of the advisory committee meeting I just mentioned, we anticipate a regulatory decision in the U.S. on August 16 for palovarotene in FOP. We also continue to expect Phase III date this year in respect of Cabometyx plus atezolizumab in second-line metastatic castrate-resistant prostate cancer. Given the recent use of a positive CHMP opinion for Bylvay in Alagille syndrome for the negative comp opinion on orphan drug maintenance, we anticipate a delay to the regulatory decision. Following the publication of top-level results from the Phase III ELATIVE trial, we plan to file for Elafibranor in the United States and Europe by the end of the year in second line primary biliary cholangitis and finally, a decision by the FDA on Onivyde is anticipated in mid-February. I'll now hand over to Aymeric, please turn to Slide 13.

Thanks, David, and hello, everyone. Please turn to Slide 14. Our financial results in the first half of the year reflects sustained top line improvement, investment for growth and a solid cash flow generation. Total sales increased by 7.4% at constant exchange rate as presented by David, a solid core operating margin at 34% of total sales, a decline of 5.6 percentage points, mainly reflecting investment for growth fueled by the rest of acquisition of Epizyme and Albireo, note that Albireo was consolidated in 2023 for 4 months since March. We have also a core EPS declining by 6.6% to EUR 4.73 per share. This is in line with the evolution of the core operating income and the free cash flow increasing by 10%, we'll come back to that. Please turn to Slide 15. Looking at the detail of the core P&L performance. The growth in total sales at 7.2% was marginally impacted by the evolution of currency in First semester. The gross margin ratio improved by 0.5 percentage points to 88.1% of sales, benefiting of higher other revenue from an upfront related to the grounding of license rights to Onivyde in the first-line PDAC indication from our ex-U.S. partner, which has offset the increase of cost of goods, driven by adverse mix in royalty pay. R&D costs increased by 40% to reach a ratio of almost 19% of total sales, in line with our ambition to invest more in our pipeline, including the asset from the acquisition of Epizyme and Albireo. SG&A costs increased by 13% with the ratio reaching 36% of sales, reflecting the commercial investment to support growth as well as several launches, including Tazverik in the U.S. and Bylvay in the PFIC indication in the U.S. and in Europe. As a consequence, core operating income declined by 7.9% to reach EUR 523 million. Please turn to Slide 16. Looking more in detail at the dynamic of the core operating margin, you can see the component of its evolution in the first half versus the record level reached in H1 2022 of 39.6% of sales. First half base business was almost flat in margin, driven the strong momentum of the growth platform and despite the gradual decline of Somatuline and the level of investment to support prelaunch activity and the investment to support our growth in the rest of the world markets. Secondly, the dilutive impact of 7.6 percentage points is coming from the acquisition of Epizyme and Albireo. This is fully aligned with our expectations with more synergies to be realized from H2 2023. Thirdly, the positive impact on group margin in H1 of 2.1 points of the Onivyde license rights upon from ex-U.S. partner for the first-line PDAC indication outside the U.S. And lastly, you know that the currency evolution had also a minor favorable impact on the profitability. As a consequence, Ipsen maintained a strong level of profitability in H1 with a core operating margin at 34% of sales. Please turn to Slide 17. Turning to core operating income to consolidated net profit, I wanted to highlight several movements. There was a significant increase in the amortization of intangible assets from EUR 46 million to EUR 91 million, mainly related to the new IP assets recognized for Bylvay and Tazverik. Restructuring and other operating expenses for EUR 125 million, mainly impacted by the integration and production costs related to Albireo and Epizyme acquisition but also the transformation program within Ipsen and the discontinuation of clinical trials. As a consequence and after a lower level of income tax, IFRS consolidated net profit declined by more than 50% while the core EPS only decreased by 6.6% with an effective tax rate at 20.4%. Please turn to Slide 18. We continue to deliver strong cash flow and maintain a very robust balance sheet after the acquisition of Albireo. As you can see, free cash flow grew by 10% to EUR 317 million, benefiting from some management of working capital and CapEx despite higher restructuring costs from the Epizyme and Albireo acquisition and lower EBITDA in line with our core operating income. Net debt at the end of June amounted to EUR 272 million after the payment of dividends for EUR 100 million and the acquisition of Albireo for almost EUR 1 billion. As a consequence of firepower for external innovation transaction, which remains our capital allocation priority, has increased to EUR 1.7 billion at the end of June 2023 based on the guidance of 2x net debt to EBITDA. Please turn to Slide 19. Based on this strong momentum, we are now upgrading our full year guidance for 2023 as David said in the introduction. We are now expecting total sales to increase by more than 6% at constant exchange rates this year. Our growth platform are set to continue performing well, and we will have further contribution from Tazverik and Bylvay in the second half of the year. Note that we now assume a 3% headwind from currencies based on the average level of exchange rate in the month of June as compared to 2 points before. We anticipate also a higher level of core operating margin at over 30% of total sales. We will continue to see the dilutive impact from the acquisition of Epizyme and Albireo, mitigated by the ramp-up of cost synergy and higher sales. In H2, we expect also an increase in R&D investment and increased commercial investment to support the potential launch of new indication and line of therapy, including Elafibrinor, Onivyde, Bylvay and palovarotene. Note that this guidance does not assume any incremental external innovation production in H2. Thank you very much. I will now hand back to David. Please turn to Slide 20.

Thank you, Aymeric. Please turn to Slide 21. Before we go to questions, please let me conclude. The ongoing execution of our strategic road map is consistently driving our growth story. The progress we are making means that we're continuing to deliver strong results. Our growth platforms are performing well, and we are seeing the benefits of our external innovation strategy, adding to the top line. Despite the significant investments in growth, we produced a strong core operating margin in the first half, while further cash generation is supporting a robust balance sheet underpinning our external innovation ambitions. The pipeline is also progressing nicely with several programs added this year accompanied by a number of favorable developments. We look forward to sharing further pipeline news flow with you in the coming months and give you more details on Ipsen's growth journey as an anticipated Capital Markets Day in London on 7th of December. Please turn to Slide 22. Thank you for listening to our presentation. We now have time for your questions. Operator, over to you.

[Operator Instructions] And the first question is coming from the line of Brian Balchin from Jefferies.

Brian Balchin

analyst
#6

Just first one. Just thinking about full year core operating margin, should we expect any more license income from Servier this year? And just how should we be thinking about cost phasing in the second half, presumably step up? Then second on elafibranor, does your EUR 500 million peak sales guide bake in competition from [indiscernible] just given the Phase III about this Q And it already looks quite derisked. And if it does bake in, do you think it will help us with your assumptions there just trying to get a sense of potential upside of the and downside?

David Loew

executive
#7

Okay. We start with Aymeric on the first 2 parts, the full year [query] and the cost savings, and then I will answer on elafibranor.

Aymeric Le Chatelier

executive
#8

Yes. So regarding your question, as you see, I mean, the first half was impacted by this milestone received from [indiscernible] . So under the agreement that we've signed, and I can't give you all the details, there are additional milestones, we don't know exactly what will be the timing of those milestones. So we have factored on a risk-adjusted basis, some limited, but the biggest one has been booked in H1. Regarding cost savings, yes, we continue to deliver consistently on our efficiency program. So we should continue to see impact of the efficiency program in H2. I think the more important will be the ramp-up of synergies that we expect also from the integration of both Epizyme and Albireo. As you remember, our guidance was more on a 12- to 18-month time line. So we will start to get some of the savings from Epizyme in the second half, and this is more in 2024, but we should get most of the synergies on the cost base to be materialized.

David Loew

executive
#9

Regarding your third question on elafibranor with the EUR 500 million guidance. Of course, we have taken into account the data that we have seen so far, including competition. That means now that we are waiting for the [indiscernible] And we have to really, really see the details to be then be in a position probably post AASLD, which is happening in November to provide you updated guidance. So we will come back with guidance. And in regards to upsides or downsides, we can really then only comment at that time point.

#10

And the next question comes from the line of Alistair Campbell from Royal Bank of Canada.

Alistair Campbell

analyst
#11

I hope you can hear me. I just had a couple, if I may. First of all, on fidrisertib, now that palovarotene looks very likely to get approved in the U.S. Does that have impact on the Fidrisertib development program? Will it need to be -- what you hope to see if you sort of look at fidrisertib versus palovarotene would you even have to consider head-to-head trials in terms of profiling that product appropriately? And then maybe I'll just chance my arm on the core EBIT and take it a bit further. I know we're too early for guidance for 2024. But as we look at sort of how things are evolving, costs stepping up in H2 this year, you still have to fully annualize the impact of the Albireo acquisition going into 2024. Can you maybe give a hint of sort of the broad trajectory for the core net margin in 2024? Is it kind of down, neutral, up?

David Loew

executive
#12

Thank you, Alistair. So I will take the first and Aymeric the second question. On fidrisertib, fidrisertib we're going to -- we are now in the pivotal trial. So we have to wait for the readout. Fidrisertib has a somewhat different profile than palovarotene. So we'll have to see once we see the full data, how we are going to position the drug. So it's too early to speculate about head-to-head or combinations, et cetera. We really have to cross the bridge when we have seen the full data of the readout of the pivotal study. And then core EBITDA 2024?

Aymeric Le Chatelier

executive
#13

Yes. So thank you for the question. As you indicated in your question, we're not going to provide a guidance for 2024. And maybe just to help you on some of the elements. You're right to say that there will be 2 additional months for Albireo as we consolidated only starting from March. But you have to take into consideration, as I said, that there will be increasing level of synergy, there will be increasing level of sales for the 2 acquisitions. So as we said when we announced the 2 deals, those 2 deals, it will take 2 years to break even from a margin and core operating income contribution. So we see less dilution, more synergy, more top line towards 2024, while at the same time, we are also investing and I said about elafibranor and Onivyde being the 2 biggest investments. And we expect also to start getting some sales -- in additional sales in 2024. So these are elements to guide on the margin. As you know, also, the [indiscernible] milestone that was a question before, is not going to be recurring, and we have also some FX impact as we talk about it in the updated guidance.

Operator

#14

And our next question comes from Manav Mastorakis from Deutsche Bank.

Manos Mastorakis

analyst
#15

First question was if you could give a bit of color on the guidance increase and what to expect in terms of the sales mix in H2 because you alluded to this port to potentially reversing the trend that we've seen in H1? And if you can tell us which products are most likely to drive most of that guidance increase. But also the you've had a string of a positive events recently. And just wondering how has that changed your overall corporate strategy and appetite for further BD and M&A?

David Loew

executive
#16

Okay. So Aymeric is going to answer on the first one, I will take the second one.

Aymeric Le Chatelier

executive
#17

Yes. So regarding your comment on the top line growth. So as you know, we delivered 7% in the first half, we're guiding for greater than 6%. So we see a similar profile in the second half of the year. But you're right to point out that the breakdown by product is going to be slightly different, mainly on Dysport, where the baseline was very low in H1, which explained to some extent, as David pointed out, the strong performance in H1. We still see a very dynamic market for Dysport. But clearly, the baseline not only was pretty low in H1, but we have catch up last year in H2, so the baseline is going to be higher. On the other way, we see increasing contribution from the newly acquired product, Bylvay and Tazverik. And we see also some further growth for Onivyde and normalization for ex-U.S. sales of Onivyde, you've seen they were negative this semester, due mainly to the ex-U.S. contribution we did that to normalize in the second half of the year. I hope it will help you to guide by product the view by the end of the year.

David Loew

executive
#18

And then on your second question regarding the positive events, you're right. So we were very happy to have those. So that bodes well for future growth and accelerating our external innovation add-ons that we have, but also our underlying base business with the growth platforms, for example, on Onivyde, or, of course, also with the new products on Alagille that we're going to launch in elafibranor. So that's very exciting. . In terms of future BD, that's not going to change. We still want to continue to fill the pipeline. So we are going to be active on the external innovation. You have seen that we are building up very rapidly, again, our firepower even after the acquisition of Albireo. So we have a strong cash generation. So yes, we are going to license or acquire potentially more medicines also in the future. That's our model, and we're going to continue to execute on it.

#19

And the next question comes from Delphine Louet Societe Generale.

Delphine Le Louet

analyst
#20

Three on my side, if I may. Looking at Somatuline loss over the semester, which was roughly EUR 70 million in revenue and the base business being up EUR 140 million. When I look at your Slide 16 and looking at the base business contribution to the core, can we think that it's effectively the breakeven point in terms of balance in between the base business and Somatuline and -- this is a way to look a bit further for the margin and for the margin dilution in the future? Second question is the one on Decap and Cabo. Decap, how should we think about the Chinese business right now? Can you give us a bit of a granularity regarding the reordering of the quarter plus any news on the pricing? Can you also detail why Germany is weak? Secondly, regarding Cabo, can you share the breakup in between the first and the second line? And/or can you give us some indication looking forward regarding the growth or the market share, whatever?

David Loew

executive
#21

Thank you, Delphine. So Aymeric is going to take the Somatuline question. I will take up the Decap and Cabo.

Aymeric Le Chatelier

executive
#22

Yes. So if I understand correctly, your question is today, we are showing that the base business is flat in margin, which means that we are able to compensate the gradual decline of Somatuline, which, as you know, is a highly profitable product by the growth of our -- or the contribution of our growth platforms in the semester. I think it is right today that going forward, Somatuline which now is only 1/3 of our total sales, the rate of Somatuline is going to decline. And we see that the growth platform will continue to contribute, and we believe that we should be able to maintain the profitability as we are been doing over this semester of all the business and be able to add progressively the contribution and the margin improvement of the new product, managing also the launch and investments of additional new products, elafibranor being one of them.

David Loew

executive
#23

So then on your -- Do you want to add something?

Delphine Le Louet

analyst
#24

No, no, absolutely not, no. Very clear. .

David Loew

executive
#25

Okay. Then on Decapeptyl China. As you know, this is an attractive piece for our business, reflecting about roughly 20% of our sales. We are going to launch the 6 months formulation where we are differentiated. Now in terms of pricing, there have been the submission of some new products, but they have not been submitted really as a generic pathway. So it's unlikely that this is going to result in a volume-based procurement because there are, a, mostly on the 1-month formulation at the market is very rapidly moving to 3 months. And in the future, we will push it also to 6 months because it's much more convenient than easier on the health care system. So we are positive on Decapeptyl in China, and we are positive for Decapeptyl overall as generally because we think it's really the backbone of therapy in prostate cancer, hormonal therapies are being given and we see longer and longer treatment duration and more demographics push with more elderly man coming in. Germany, I mean I'll let Aymeric perhaps say a word to Germany.

Aymeric Le Chatelier

executive
#26

Germany on Decapeptyl, I think this was a very minor impact. What we wanted to highlight is that all the geographies are growing in volume, except Germany, for very specific, but just as a reminder, Germany is less than 5% of the sales of Decapeptyl.

David Loew

executive
#27

And then on Cabometyx. So the split of first and second line is roughly 1/3 first, 2/3, second line. You're going to see this change. The first line is growing much faster than the second line, and the dynamic is the following. We're still launching second line in some of the emerging markets. On top of that, we have started to launch beyond the leadership position that we already have in second line in most of Western markets. We have started to launch in the first-line indication in several markets like Germany, France, Italy, very recently. And the pool of patients in the first line is at least 50% bigger and the treatment duration is also roughly 50% longer. So when you add that together, it means that in every market where you launch first line and we have now launched it in 20 markets around the world first line, there will be a much higher sales coming from that first-line indication. The market share already developing quite nicely. So we have roughly 20% of the first line and we hope to grow this further.

And the next question comes from Charlie Harwood from BofA.

Unknown Analyst

analyst
#29

Charlie here with Bank of America on behalf of Sachin Jain. Two please. Firstly, on your Bylvay on great launch, you had EUR 18 million sales in the quarter versus EUR 5 million sales in March, which was slightly more modest growth than the apparent first quarter uptick. So firstly, can you talk about your penetration into the PFIC market and your current share in market dynamics versus Livmarli launched recently? And secondly, how are you thinking about your Alagille syndrome launch with Livmarli orally well penetrated and seemingly like little different takes on efficacy? And then second question, please, on your recent elafibranor data. How compelling do you view the [ overall ] data profile? And then how important do you see the lack of statistically significant pruritus versus imminent consumer base of PFIC competition that could demonstrate statistical significance on pruritus?

David Loew

executive
#30

Thank you. It was a little bit hard to hear you. Your line is not very good, but if I understood it right, your question was build a first quarter EUR 5 million, second quarter total EUR 18 million and then the penetration in PFIC. So we are penetrating relatively well in PFIC, but there is much more to go. We are not giving out market share yet. We have heard regarding your question on Alagille, we believe that [ Neuro ] has about 20% market share in Alagille. So there is plenty of space where Bylvay now take market share. Of course, some patients are also not going to tolerate the drug or they will have a strong preference for the clinical formulation, which is in our new easier to take. So we hope that we're going to get significant market share also in Alagille. So we assume that Bylvay is going to continue to grow very strongly. Regarding your second question on elafibranor, how compeling is the data? Well, first of all, we have to be super careful on cross-study comparisons. I mean, as you know, we passed Phase III, ultimately was stopped. They have reinitiated a new trial. So some of the endpoints are very early, like pruritus has been measured, for example, at 3 months. We have data at 12 months. So you need to be very careful. You also have to look very carefully at the underlying demographics, where differences can play a very important role. So we can't really say how compelling our data is versus Livmarli because we clearly need to see their results and not just the press release, but we actually need to see the results in detail. So if they seek to what they have told the market that they are going to publish in Q3, that would mean they could have a late break curve potentially for AASLD if their data is compelling, and we are going to, therefore, potentially see the data AASLD. And that's when we really can tell you the answer to your question. The lack of pruritus, as I said, you can't compare to Livmarli because they measure that 3 months, we measure that 12 months. The fact that the trial was positive on the primary endpoint and the first secondary endpoints, which are the outcome is, of course, really very important. So we are delighted about that because these patients are in dire need of new solutions. Of course, on pruritus -- and we would have loved to hit this one as well, but there was a trend and we keep it quite achieve statistical significance.

And the next question comes from John Priestner from JPMorgan.

John Priestner

analyst
#32

John Priestner from JPMorgan. Just 2 from our side. So the first one on Bylvay. So Q2 looks strong. Was there any contribution from Alagille syndrome at all here? Or was this all PFIC? And obviously, just also thinking about the positive CHMP but the negative CHMP opinion for Alagille syndrome in Europe? How important is the Botox drug designation to approval and also exclusivity. What are the potential implications if it was approved without orphan drug designation, just trying to think about the dynamics relative to the Livmarli, which is obviously already approved here? And then the second question on Dysport. We're just trying to understand how much in capacity have really in terms of continuing to service the strong growth we've seen ex-U.S. And maybe just any more commentary about what was leading to the potential weakness in the U.S.?

David Loew

executive
#33

Yes. So on Bylvay, the sales that we have seen really come from PFIC, there is no Alagille contribution yet because we have just gotten the approval in the United States end of June. And then to your second question on Bylvay regarding the positive CHMP, we're, of course, delighted because they see the benefits of the drug. So it's clearly an approvable drug. There is, of course, the negative opinion of the COMP regarding the orphan drug status. And the question is how important is actually orphan drug status? So orphan drug status has 3 points considered. The first one is you get a faster review typically by regulatory authorities. In a way, that's where they're under the bridge because we now got the positive opinion of CHMP. So the first point becomes kind of irrelevant. The second one is it can confer to you an additional protection from generics if you would have a short substance patents, but our substance patents is actually fairly long. It goes until July 2036, at least, and potentially longer. So the orphan designation protection would come as a supplement to the base patent. But it would not -- it is actually slightly shorter than the substance patent. So therefore, it has a certain importance, but we have optionality's there. Now we still felt we wanted to appeal. And that appeal process is actually fairly short, so we should see an approval by the end of this year. Regarding your second question on Dysport capacity, we have enough capacity now. As you know, we have upgraded our capacity. We will still further add capacity because we believe that the neurotoxin franchise is a very attractive franchise for us in aesthetics and in the treatment space. And so we are continuing to invest. And as we speak, we're actually starting with the construction of an additional building, but that's really for the long-term forecast on our neurotoxin franchise. And then your question on weakness in the U.S. What we think is happening is that the U.S. market is softening a bit, but it remains to be seen how persistent that is going to be.

And our next question comes from Colin White from UBS.

I just had a couple of questions. First on Tazverik. I was just wondering when you think you'll start to show a change in momentum and when you think things are your strategy is going to help to start picking up? And the second question was on palovarotene and your thoughts after the AdCom and your level of confidence in that the FDA will follow the AdCom recommendation given some of the behavior so far?

So on your first question, thank you, Colin, regarding Tazverik. We are starting to see the first markers of uptake in the new positioning. You need to remember, Epizyme has positioned this in the academic centers in mutant patients. And what's happening there is we knew that the bispecifics are coming in there and also the CAR-T. So it is clear that we're potentially going to lose a little bit of sales in the academic and that is what is playing out. At the same time, we're starting to see a pickup in the office-based physicians because that's where the elderly frails lower progression patients are. And there, indeed, we started to see a faster uptake since we have deployed our field force, which before was not really the case. So these 2 effects are playing out against each other, and that's why you see the 18% growth rate. So it's going to be kind of a bit of a slow burn, a gradual increase that Tazverik is going to have. And then, of course, you're going to have potentially a much bigger step once we get the second line indication trial readouts and registered. Regarding Palo, you have seen 11 votes were in favor out of 14. Usually, the FDA is following that recommendation and the interactions with FDA are going according to plan.

And the final question comes from Livon Deminokian from Redburn.

Two quick ones, if I may. First one, can you give us a bit more granularity on the second half margin push and pulls? And then can you give us your thoughts on the scope of broadening the potential for recently appointed assets like Tazverik in solid tumors or Albireo's early pipeline like A3907?

David Loew

Yes. So Aymeric is going to answer you on the first one, I'm going to answer you on the second one.

Yes. So regarding the margin for the second half, as you see, we delivered 34% in the first half. We're guiding for above 30% for the full year. So even if you adjust for the one-off from the Servier milestone, there is clearly a lower margin in H2 which will be driven not that much by the top line, as I explained before, as we anticipate a similar top line. It's more related to 2 elements. It will be additional investment, mainly in R&D, but also commercially to prepare for some of the launch and in R&D to support especially the ongoing study that are going to be -- that are being large most positive data for elafibranor and also will have some negative impact of the FX as we anticipate a significant impact of FX in the second half of the year.

And then to your second question regarding potential broadening of the Tazverik , but also the other components from Albireo that we have in the pipeline, I'll start with Tazverik. In solid tumors, we have a prolonging in prostate cancer. That is in Phase II in combination with hormone therapy, you have all the details of the trial in the attachment of the slides. So we have to just wait for data to then take a decision, okay, where are we going to take it from there. We all have on Albireo on the IPN60250 formerly called the A3907, a trial ongoing in Phase II in primary scloroiling cholangitis. So again, we need to wait for the Phase III data. And again, you have the details in the attachment. And the same is true for the formerly called A2342 compounds, which is now IPN60260 in viral cholestatic disease that's actually hepatitis D often in combination with. Again, we need to see what the Phase I results are going to show before we can determine where we are going to take these drugs or we are going to accelerating slowdown stock, et cetera. So we need to really wait for the data. So with this, that concludes our call. Thank you very much everybody for having attendance. Bye-bye.
