Good day and thank you for standing by. Welcome to the Fourth Quarter and Full Year 2024 Ascendis Pharma Earnings Conference Call. At this time, all participants are in a listen-only mode. After the speaker’s presentation, there will be a question-and-answer session. [Operator Instructions] Please be advised that today’s conference is being recorded. I would now like to hand the conference over to Scott Smith, Chief Financial Officer. Please go ahead.

Thank you very much, Operator. And thank you everyone for joining our full year 2024 financial results conference call. I’m Scott Smith, Chief Financial Officer at Ascendis Pharma. Joining me on the call today are Jan Mikkelsen, President and Chief Executive Officer; Sherrie Glass, Chief Business Officer; Jay Wu, President, U.S. Market; and Aimee Shu, Chief Medical Officer.

On the call today, we’ll discuss our full year 2024 financial results and we’ll provide further business updates. Following some prepared remarks, we will then open up the call for questions. With that, let me turn it over to Jan.

Thanks, Scott, and good afternoon, everyone. 2024 was a pivotal year for Ascendis as we achieved key milestones that set us up to deliver strong growth and value creation in 2024 and beyond. With SKYTROFA firmly established as a high value growth hormone brand in 2024, volume grew sustainable with revenue reaching around €200 million on a 6.5% market share of the total growth hormone market in the U.S. and around 45% of the total U.S. long-acting growth hormone market based on third-party prescription data. With further penetration in pediatric growth hormone deficiency and a planned commercial launches across multiple indications and countries, we expect sustained value creation for the TransCon Growth Hormone branches in the coming year as outlined in our Vision 2030. Importantly, YORVIPATH, the only FDA approved treatment for hypothyroidism in adults, is now launched in the U.S. and has already begun to establish itself as the new standard-of-care. Given the longstanding need for a treatment option like YORVIPATH, we are seeing significant early demand in both the patient and physician communities, and we are pleased with the pace of payer approval so far. The large global population living with a significant hypopara disease burden underscores the potential for YORVIPATH to grow into a multi-billion-dollar product over time. Rounding out our endocrine rare disease portfolio, TransCon CNP clinical data demonstrated it could be a highly differentiated product with a unique profile that represents a major step forward in the treatment of achondroplasia and other growth disorders. We believe the once-weekly TransCon CNP data demonstrates superior linear growth and benefits beyond linear growth, supporting our proposed label for treatment of achondroplasia. For this reason, following our pre-NDA meeting with FDA, we are on track to submit an NDA to FDA this quarter, followed by an MAA submission to…

Thanks, Jan Mikkelsen. The progress we made in 2024 enables us to head into 2025 with the financial and organizational strength to execute on our strategic priorities, which are to successfully launch YORVIPATH on a global basis, to build on SKYTROFA’s leadership position in pediatric GHD by expanding the U.S. label to adults while maintaining its premium net pricing of 3x compared to daily growth hormone, and to submit TransCon CNP for approval to treat achondroplasia in children in the U.S. and the EU. I will touch on some key points surrounding our fourth quarter and full year financial results, but for further details, please refer to our 20-F file today. SKYTROFA volume increased 37% in the fourth quarter of 2024 compared to the quarter last year, while reported revenue was €58.5 million, compared to €64.2 million reported in the fourth quarter of 2023. In the fourth quarter this year, SKYTROFA revenue benefited from volume growth and a favorable sales adjustment of €4.6 million attributable to periods prior to January 1, 2024, which was offset by higher sales deductions compared to the same period the prior year. Backing out this favorable sales adjustment, SKYTROFA revenue was approximately €54 million for the quarter. Sequentially, SKYTROFA volume increased 16% in Q4 compared to Q3, while pricing was stable. We expect revenue growth to continue to track closer to script growth unless payer mix changes substantially, as there have been no major contracting changes compared to Q4 last year. Shifting to YORVIPATH, as previously reported, fourth quarter YORVIPATH revenue increased to €13.6 million, bringing total 2024 revenue to €28.7 million. As Jan noted, the launch of YORVIPATH in Germany and Austria in 2024, together with the initial demand and progress with reimbursement in the U.S. so far in 2025 has been very encouraging.…

[Operator Instructions] Our first question comes from Jessica Fye with JPMorgan.

Hey, guys. Good afternoon. Thanks for taking my question and congrats on the strong YORVIPATH script number and breadth of subscribers. I have one question with a few parts, mostly just confirming some stuff. First, can you confirm that the 908 figure is unique patients and not like cumulative scripts, including refills, for example? Second, can you just confirm how many of the EAP and OLE rollover patients are now included in that 908 number? I want to make sure I heard you. I think you said it was 84% new to YORVIPATH, 16% from the EAP and OLE. Lastly, I think you reiterated that you continue to expect the majority of insurance approvals will take four weeks to eight weeks. Can you just confirm that’s actually what you’re seeing now that you’ve been in the U.S. market for coming up on eight weeks? Thank you. Thanks, Jess, a lot for the questions. I think we can confirm nearly all the answers. So, Jay and Sherrie, will you confirm all the numbers? So be sure.

Happy to. Jessica, thank you for the question. The first part of your question, from an enrollment standpoint, we can confirm that is unique patient enrollments. So not cumulative repeat. I think the second question you asked was the percentage of patients that are coming over from either the EAP or clinical trials versus those that are new to YORVIPATH. So about 20% of the 908 is existing patients from TransCon PTH, EAP or clinical trials. And then 80% of patients are actually new to YORVIPATH. And then the third question that I think we heard you ask, Jessica, is more around the four weeks to eight weeks. That is our estimate of what we think it should take. But keep in mind, too, that based on the timeframe for which the drug has been on market, it is still a very nascent period of time where, for many of the patients enrolled, that time period hasn’t actually occurred yet, right? So we’ll need more time to get a better sense of that. But that is our initial estimate today.

Thank you. For my follow-up, can you provide the YORVIPATH patient number outside the U.S.?

We have not broken that number down. It’s still increasing as we expected to do. We are still only in Europe-directed countries, full commercial in Germany and Austria. We have our AP2 program in France, a non-promotional program that also is enrolling reimbursed patients. And then we have our international market in this way. And the patient numbers are increasing to exactly as we have expected, but we have not broken down the numbers.

Our next question comes from Tazeen Ahmad with Bank of America.

Hi, guys. Good afternoon and thanks for taking my questions. Jan, could you provide any color on how many of the 908 scripts that have been written have now been converted to patients on actual therapy? And can you give us also any color that you might have on what proportion of these patients may have had previous experience with NATPARA? And then I have a follow-up.

Yeah. The question you are addressing is a question where we still lack all the information to give you really the concrete answer that you want to have. What we have done in our market research, we have looked a lot on claim data and we have defined a patient group, which we call the 10,000 to 15,000 patients, which we will call not controlled on standard therapy or conventional therapy. And this patient group is basically seeing the physician at least four times a year. And they also will have one thing more in common. They have at least one hospitalization related to the disease. And we also know the limitation in really that is in seeing an endo. So often that perspective, just by the random process, when you can see an endo, we actually believe that many of the patients that we see of the 908 actually are coming from the group, which we define as more uncontrolled in this. We don’t have a positive definition if that is true or not, but that is our expectation in this. The second question you raised about how many patients we have on therapy now, is a number we are waiting to some way to come out with until we feel we have sufficient, good enough data to give you a solid number, because we are now in the initial part of our, you can say, journey of getting them 100% reimbursed. We were extremely positive on the broadness of having reimbursed patients, both from the commercial set up, but also for the government side. And we basically are getting reimbursed patients every place from. And when you see the broadness on the state we’re covering with about 35 different states, we’re really coming out in all different states. We’re also feeling that we are in a very, very strong position. The vast majority of the patients are unlabeled and basically they’re also fulfilling exactly the criteria that justify for them to be on a PTH treatment. So we are really highly positive on the development we have seen in the reimbursement spectrum.

Okay. Thanks, Jan. And then I just wanted to clarify, I think you had said that you were considering providing sales guidance for YORVIPATH for the full year, sometime in the middle of the year. Does that still the plan?

I think it’s still the same. I think we would like to give you guidance when we believe in the numbers and I think that is the criteria we take up. So depending on how we see the launch going and how we see different regions, we will come up with what we call revenue guidance exactly when we’re feeling that we feel the confidence. Scott always like to give up a lot of numbers. So you can hear in his list and what he said in he prepared remark that he will come up with a lot of elements that can give you the best possible fundament to build up a solid model in your own way. Comments to you, Scott?

Yeah. We will. As we said, we’re excited to continue to share with you the underlying parameters driving the launch and we plan to do that in the quarters ahead.

Our next question comes from Gavin Clark-Gartner with Evercore ISI.

Hey, guys. Congrats on the very strong progress so far. Just had one question on your YORVIPATH and one on CNP. For YORVIPATH, how have your discussions with payers gone so far and what are your assumptions for how some of the prior authorization criteria may read? Specifically wondering if you think it’s going to be different than the label. Kind of on that same line, maybe you could just remind us your contracting or gross to net assumptions. That’s the first one. On the CNP side, for the CNP plus growth hormone combo data coming in the second quarter, can you just remind us your expectations specifically on AGV? Thank you.

Yeah. I think Jay will come with some flavor about the contracting situation. But also, as I said before, I’ve been lucky to see most of the UN criteria and I have been really pleased how they’re aligning to the labeling. But I believe Jay will come up with comments related to the commercial contracting landscape.

Yeah. So thank you for the question. As you can expect for any new launch, we are still in the early stages of establishing policy with payers. So just as an example, most medical policies right now for our large national players haven’t yet even published a policy yet, right? So our conversations have all been productive to-date, really focusing on the clinical value proposition of the drug. As you can see, and based on our data from our array of clinical studies, we feel really positive about the benefit that we can convey to the patient community and we’re having a great conversation around that. Specifically, your question around prior auths and what that might look like, we’re expecting. And again, as part of those negotiations and discussions, wanting to ensure that the standard is consistent to label, both in terms of reauthorization timelines, tests that may need to be conducted to ensure that, again, it is consistent with label. So while many of those plans and policies still need to take some time to come into fruition, we’re feeling encouraged by those conversations.

So the CNP question is always looking in the crystal ball. Because you asked me, Jan, what is your expectation to a data you have not really seen? And it’s the first time, to my knowledge, everyone has done a combination trial in achondroplasia, a Phase 2 trial between TransCon CNP and growth hormone. And why I think it’s really, really interesting, because it’s two different compounds with very different physiological mode of action. And if I ever believe in science, which I always do a lot, it should be a great combination, because it’s synergistic pathway. And when I look on what you can do when you address the hyperactive tyrosine kinase system that you have in achondroplasia, you can do that with either the tyrosine kinase inhibitors, you can do it by CNP as short-acting or you can say continuous exposure. I think it’s easier to saturate the analyzed height velocity in this part of the integrated effect you expect to give as a treatment option in achondroplasia. One of them that’s easiest to hit is basically the analyzed height velocity. And when I look on all the data, it’s likely are going around 5.5 to 6.0 on analyzed height velocity, which basically are reflecting a little bit what the science also will say, you are moving a brake and you restore normal growth. So out from that perspective. And this is why I love the growth hormone, because what is growth hormone? This is like sitting in a car, and then you get rid of the speeder. Somebody take a little bit on the speeder, get the brake off, and then you really can move. And this is why I feel this combination will give a good result. And I look forward to the results as much. I can ask you, what would a good result be, Gavin?

That’s helpful. Thanks, guys. We’ll leave it there for now.

We don’t. We don’t.

Our next question comes from a line of Li Watsek with Cantor Fitzgerald.

Hey, guys. I wanted to add my congrats on the strong YORVIPATH launch as well. Just curious for these 900 plus prescriptions, what proportion of these patients have more severe versus more moderate diseases? And if you can share any early trends, if compliance and initial titration, whether it’s consistent with your clinical trials?

Yes. It’s a question we tried to address before. But I think, Sherrie, you’re also sitting with a lot of data. Potentially, you can somehow describe the limitation that we have in our data set, really, to answer that question today.

Sure and thanks for the question, Li. So what -- we don’t actually have data in terms of the enrollments on patient severity. What we do know, though, is a couple of important things. One is that, as Jan said earlier, the most severe patients are going most frequently to the endocrinologist. So by that practical matter of them getting into the office to get the prescription, it’s likely that we have severe patients initially getting some of the first prescriptions. And as Jan also mentioned, there is a -- there are a number of those uncontrolled patients in the U.S. There’s 10,000 to 15,000 of them, and then a number more of people who are partially controlled. So to the extent that we are starting to see some of the first patients being the more uncontrolled and severe patients, we know there’s still a tremendous amount of room for expansion beyond that.

Thanks, Sherrie.

Thank you.

Our next question comes from Derek Archila with Wells Fargo.

Hi. This is Yvonne [ph] for Derek. Thanks for taking our questions and congrats on the progress. A quick one from us on YORVIPATH. So can you provide some color on what type of docs are prescribing YORVIPATH? Are these, like, high-volume docs or are you starting to get some docs from the community? And as a follow-up, how long do you expect patients will take to convert from drug in the EAP over to paid drugs? Thanks.

Yeah. Let me take the last question before I throw it over to Jay or Sherrie. What is happening in our EAP program, the last packet I got was a three-pack of basic three months and some of them got them in December to in January. So the 100-plus patients that we are converting from our EAP clinical trial over, we’d likely come into commercial drug starting in February and then the majority in March. So that was the second question. And I think Sherrie or Jay, who will take this? Would you start, Jay?

Sure. Happy to start. I think the question around prescriber breath, I think, as we mentioned before, 539 across 44 states. We’re seeing that pretty broadly across all different types of physicians, across all deciles. Naturally, you would expect directionally, physicians that are treating perhaps a greater number of patients, right, we’re naturally also focusing on them quite heavily. So from a field standpoint, we’re actually over 50% reach for a lot of our priority physicians. So I think naturally, you’re going to see some directional lean in that direction. But more importantly, what you’re seeing is a broad outreach and broad interest across the provider community agnostic of this [ph].

And maybe I’ll just add that to that, that what is really exciting is that we see that we’re broadening a lot beyond the NATPARA prescribers. So of the 539 physicians, only about 200, a little less than 200 had prescribed NATPARA. So we see that we’re really broadening our reach.

Thanks.

Our next question comes from Yaron Werber with TD Cowen.

Great. So thanks so much. I got maybe a couple of questions, Scott, for you. And then I don’t know, Jan, if you want to take the next one. I think, Scott, you said that toward the end of the year, you could be -- you could reach profitability on a cash basis. Does that still sort of hold? And what would drive that? How do we -- is it going to be YORVIPATH is the biggest driver? And then secondly, as you think about reimbursement for YORVIPATH, are you expecting with time prior authorizations or are you expecting not to have any prior auth? Thank you.

Okay. I think Scott would like to say something.

Yeah. I think you’re exactly right. YORVIPATH will be a big driver of the ability to cash breakeven. It’s a strong launch in Europe for us. Obviously, we’re off to the races here in the U.S. and it’s a very profitable product. So I think we agree that that’ll be a strong driver of breakeven potential this year.

Yeah. But I also believe you need to look that U.S. is the numbers we’re giving you today. But we basically have a global effort. And we also, some way, seeing that end of this year, we’re starting to take it to a much, much higher gear in our Europe direct countries. We will also see the international market is starting to really, really getting engaged. I accept that it will be a major event for 2026, where all the countries will come in, mainly with full year launches in for many of them. But the 2025 will be where we start in both the Europe direct in at least five countries more, but basically also our international market. So the U.S., sure, it’s a fast market. It’s a fast penetration we can get because it’s so large single market. So sure, it will dominate in the beginning of the year. But just remember the number of patients outside U.S. with hypopara is so much, much, much larger, perhaps four, five fold than what you have in the U.S. The second one, will -- do you take that, Jay?

Yeah. Sure. I mean, from a prior auth standpoint, I think the question was, what do we expect for YORVIPATH? It is a specialty product and I anticipate there to be some basic questions, even if it’s simple as who’s prescribing it, right? I think whether it’s an endocrinologist, whether it’s a nephrologist, et cetera. And I think secondly, what you’re going to see and should expect is there’s going to be wide heterogeneity across what you’ll see across both national and regional plans. I think as we alluded to before, we are seeing approvals across commercial payers, public payers and even absent of there being a formalized policy at some of the large national payers, we still submit generic prior auths to seek exception through that policy. So again, some of this will take time to evolve and some of it we would expect to change, but we will see probably a wide range across the various plans.

Our next question comes from the line of Joseph Schwartz with Leerink.

Hi. I’m Joori Park dialing in for Joe. Thank you for taking our questions. I believe in the last earnings conference call, you mentioned that in Germany, physicians are prescribing YORVIPATH to one to two of their patients, whereas in the U.S., you are expecting physicians to prescribe the drug to two to three of their patients. And based on the metrics that you provided today, it seems like on average, each physician is prescribing of a drug to a little over one and a half of their patients. So I was just wondering if you’re still expecting each physician in the U.S. to prescribe YORVIPATH to about two to three of their patients? And where does it go from there?

Yeah. I think in some way, I accept what I said and I stand by what I said before. And I think the pattern we see now is an early launch. I have seen and followed some of the physicians that were part of our EAP and clinical trial. And one of -- some of these physicians have already made prescriptions up to 20 patients. So no doubt the broadness of that will come. But in some way, this is an early launch, one to two months in the launch. So I would expect that to see and come in the future.

Okay. Great. That’s helpful. And then a clarifying question. Are there any -- are any of the 908 prescriptions included in the YORVIPATH sales from 2024, considering the drug was available mid to late December? Thank you so much.

Got it. I mean, strictly speaking, so we did ship a very small amount in December. It was basically immaterial to the total.

Yeah. So in practical, no.

Our next question comes from the line of Kelly Shi with Jefferies.

Congrats on the great quarter. And on the manufacturing front, how should we think about the capacity to meet the increasing demand of YORVIPATH throughout the year? Thank you.

Yeah. I think one of the things we have been very, very proud of at Ascendis is really our robust supply chains. And we have seen how we have managed to go up in high demand on the shortest of the daily growth mode and could fulfill all requirements for all issues for having, for example, the scratch over brand. And when I look at the YORVIPATH, we’re using the same solid supply chains, the same infrastructure. We follow the same way. I personally get a weekly report on every compound in every region, in every place where we are selling product, how many months that is on storage. And we some way are taking that as a really serious thing because we will never be in position that we will go short and that is our vision, and I hope we never come to this.

Thank you.

Our next question comes from the line of Ellie Merle with UBS.

Hey, guys. Thanks so much for taking the question and congrats on the launch progress. Just in terms of how we should think about the U.S. YORVIPATH script cadence, I guess, sort of what’s the latest that you’re seeing in terms of the cadence of new starts? Are you sort of seeing a steady number of adds each week? Was there a bolus up front? How should we think about this going forward? And second, just a follow up on reimbursement. I know you said you’re seeing approvals across a number of plans, but could you characterize maybe sort of the number of scripts that have been covered so far and sort of any trends that you’re seeing in terms of ease of reimbursement, say, between the moderate patients versus the severe patients and your expectations there? Thanks.

I think the question related to what we call control to party control and patient we have somebody answer this to our best of knowledge. We have no clear data of the patients that is already have received a prescription. We have a gut feeling and the gut feeling is that we believe many of them belong to the uncontrolled part because they see the endo in a much higher frequency than anyone else. Related to the pattern of prescription, we are not breaking it down in weeks or anything. This is something we are following where they are tied and we would like to see a pattern being developed. We don’t believe that’s really a huge bolus coming in because there is not a huge availability by the endo really to come in and say, oh, I just want to have an appointment run into an endo and now I have a prescription. It’s not like life. It is, like, Aimee sitting here. If you want to see Aimee, our CMO at Stanford, it takes how many weeks now, Aimee?

12.

12 weeks to see her. So it takes a little bit of time to get an appointment. So we don’t believe that it’s a lot of build up demand. It basically is patients that come in and have the need to be on a treatment. And I think it’s pretty obvious for me when I see the benefit of all the patients get, yes, everyone should have a treatment option and come on PTHs like everyone on type 1 diabetes should have insulin. This is a hormone replacement therapy in this perspective. Related to the reimbursement system, I do not know, Jay, if you have further comments, compared to that.

Yeah. As we mentioned before, because this is such early days, I don’t think we would be able to draw a meaningful pattern or a trend based on just the few weeks that we’ve been in here. I think I go back to the statement we made before. We are seeing approvals across all both commercial and public payers, but fully recognizing too that because many policies aren’t in place, a lot of these cases are exception by exception basis and we believe that after at least a few more months, we’ll have a better sense of how these policies shake out and what that more stable trend should be.

Great. Thanks.

Our next question comes from a line of David Lebowitz with Citi.

Thank you for taking my question. First on SKYTROFA, you had the PDUFA date coming up this summer for the adult growth hormone deficiency. I’m just curious, how should we be thinking about that in terms of what that market opportunity actually presents?

Yeah. I think, Aimee, can explain on the unmet medical need that really exists in adult growth hormone deficiency. From my perspective, there’s two key things I really, in some way, are reflecting over a lot. First of all, it’s an error with extremely low penetration to our best knowledge is under 5%, 6%, 7%. So you can say there is a huge opportunity for growth. And the other thing is that has been a huge burden basically to be in the treatment with daily growth hormone. But Aimee, you can explain and tell about what is really the unmet medical need, the burden of having adult growth hormone deficiency.

Sure. Happy to do so. So many people arrive at growth hormone deficiency in adulthood following something involving organically the brain, right? So a brain tumor or a brain cancer or its treatment, either surgery or radiation, that’s at least 50% or more. So many of them, because they are missing function of the pituitary gland, are taking many hormone replacements and growth hormone is just one on that list. So they have oftentimes said, if I -- if it’s something we can make simpler, right, that the community could provide more simply to them, they would, it is something they would consider, knowing that it adds to their metabolic health and overall endocrine health, right? But of course, their first priority always are the two life-saving hormones from the brain, that is from the adrenal gland and the thyroid gland. So those you can’t forget and those are pills. After that, they are willing to think about injectable, less frequent therapies, knowing it is good for their overall health. We could admit that growth hormone deficiency is not immediately life-threatening the way that if you don’t take thyroid or adrenal replacement is. So we think we’re in a nice, sweet spot here. It’s a hormone that should be replaced and if it meets patients’ expectations, we think they would be taken.

Thank you for that. And just jumping over to YORVIPATH. I’m just curious as to thoughts on potential competing pivotal data coming out this year and how you think the market ultimately might evolve?

Yeah. If you reflect on pivotal data, I don’t think there is anyone else than one compound, the amyloid compound. And to our best knowledge, when we talk with centers, the last patient in was in the beginning of November. So I’m still waiting to see the results of the pivotal trial. It’s a small trial with a little bit more than 100 patients. So it shouldn’t take too long time to clean the data and come up with the topline data. But I have not seen anything else. When I go back to the science and one of our key values, this is not a hormone replacement therapy. This is a substitution of the long-acting effect, where you basically are placing part of the receptor system into a fixed position and therefore have a long-acting effect. It’s not even reflecting the normal biology where you are basically activating both the PTH1 receptor and the PTH2 receptor. And by doing the different mode of action, you already are from the data can see that it can never substitute as a hormone replacement therapy element where you see it’s not restored normal function, for example, in the kidney, for example, related to phosphate excretion. See, for example, it cannot lower a key element like calcium phosphate complex. You also see the unnatural activation to the activating system in the bone and other organs. And then I’m not talking about the hemogenic potential that is in the compound. So we are looking forward to see the data. We would like to see the data and we hope one day it will come out. There should be out there now because it’s so long time since the last patient came into the visit.

Our next question comes from Paul Choi with Goldman Sachs.

Hi. Thanks. Good afternoon and congrats on the early launch success with YORVIPATH in the U.S. My first question is on YORVIPATH. And as we look at consensus numbers, the street is modeling less than 900 patients in the U.S. for this year and you’ve already exceeded that in terms of scripts. So I was just wondering, recognizing that you’re not giving guidance and not and the reimbursement is a work in progress, just your level of comfort with the street, a revenue number for the full year possibly or any color around that would be great. My second question is regarding CNP and the hypochondroplasia program that you plan to file an IND for later this year. Are you planning to do any run-in activities ahead of that, possibly at some of the centers just to potentially help accelerate the timing of that study? Any color there would be helpful. Thank you very much.

Yeah. Let me take the first part together with Aimee, because we are really dedicated to be the leader in growth result. And when we see the two cornerstone we have TransCon Growth Hormone and TransCon CNP. We really will do the best for the patient in each cases. How can we design an optimal treatment in this way? And what we’re doing now in hypochondroplasia is defining what is really the pathway forward for us. Is then just a TransCon CNP treatment or will it be a combination treatment between TransCon CNP and TransCon Growth Hormone? And we are now in a position that we are starting the discussion with regulatory agencies. But I think Aimee can give you a little bit of background. Why we think that when we’re moving into hypochondroplasia, it’s one of many growth disorders we actually would like to focus on and the actual design can also be a different state process.

So exactly, we are taking the time to give hypochondroplasia the opportunity it deserves. While some of hypochondroplasia overlaps highly with achondroplasia and the genetic variant arises on the same FGFR3 receptor. The gene changes are very different along that whole receptor and we are understanding that hypochondroplasia has a unique phenotype. It’s a broader phenotype and very unique. So along those lines, we are still figuring out, it’s an active process, what’s the population of interest to us, where we can benefit from them, and therefore, the different ways to find a regulatory path forward, which I think gets to your question about how much time do we put into the run-in. So I couldn’t tell you now as we are still figuring a lot of this out, but I think the condition and other conditions of short stature, especially on the skeletal dysplasia genetic side, right, deserve a very good, thorough understanding to find the best way to accomplish it.

We are in this position that potentially we will start both trials at the same time, and CNP and a combination trial, and then we will basically evaluate the data and find out that potentially we will go for an approval for both, and then they can choose the optimal treatment from the position, how the best can serve the patient needs in this way. If they really want to have a much more extensive linear growth, likely the combination therapy will be the preferred option. Related to your last first question, I think we said in Scott’s prepared remark that we are not giving any guidance, as you correctly said. We would like to give you as much as possible what we can call elements we are using in our own modeling and giving that as fast as we can give it with all the different goals to ensuring that you have the best possible modeling that you can do, and I think, Scott is always open for discussion. He’s extremely extroverted and likes to talk with people, so I think if there is any element of model discussion, I think he likely will engage in it.

Our next question comes from the line of Alex Thompson with Stifel.

Hey. Great. Thanks for taking my questions. I guess on YORVIPATH, I wonder if you could talk a little bit about how titration is working in the real world with patients, whether that requires additional visits with their HCP, et cetera, if this is done at home? And then maybe could you talk a little bit about your expectations around growth and that stability in 2025 for SKYTROFA? Thanks.

Aimee, would you take this one?

Sure. The first question was about titrations with YORVIPATH. From what we’ve seen so far, right, this is in the domain, this is the sweet spot for endocrinologists. They know how to titrate medicines. So we are -- but that being said, I’m not sitting on the shoulder of each prescriber and I can’t see what they’re doing week-to-week. I think so far they have found it straightforward to follow. They have gotten the guidance that they wanted, and the only times we may have touch points with them will be as we go further along and one switches from the medium dose pen to a high dose pen or a low dose pen, but we don’t have that insight yet. But from what we’re hearing just anecdotally, it’s what endocrinologists know how to do.

At least what we have seen now, but being in market in Germany for one year now, we are not seeing any issues to the titration and patient-physician field that is not complicated and easy element to do it, and they’re getting up on conventional therapy exactly at the same speed that we saw in our clinical trials, which surprised me a little that they’re doing in the same speed as we do when we have much more regional framework for a patient to come into and talk with the physician. It’s the same thing happening in real life. They’re out of conventional therapy extremely fast.

Our next question comes from the line of Yun Zhong with Wedbush Securities.

Excuse me. Good afternoon. Thank you very much for taking the questions. The first one on YORVIPATH. So when you report first quarter earnings, are you going to break down sales to tell us how much is coming from Europe, how much is from U.S., please?

That’s a good question. We will decide when we come to that state exactly how we report the data.

Okay. Then follow-up question on the SKYTROFA. I believe what I heard was that the adjustment has largely been over for 2024, but you haven’t really given any guidance, unlike in January last year, you put out the guidance for 2024. And are there any uncertainties surrounding the schedule? Is that related to the adult launch or more related to the pediatric market, please?

Yeah. Thanks for the question. So, we expect revenue growth to continue to track closer to script growth going forward, unless, of course, there’s payer mix changes, substantial payer mix changes and this is primarily because there’s been no major contracting changes compared to last year -- Q4 last year.

That’s all the time we have for questions today. This concludes today’s conference call. Thank you for participating. You may now disconnect.

Thank you. Bye-bye.
