spk01: Thanks, John. 2023 was another impressive year for Orladeo, starting with generating $326 million in revenue in just the third year of launch. We continue to make great progress toward our goal of global peak revenue of $1 billion. Let me explain why. Late last year, we laid out a set of assumptions that would lead us to $800 million in peak sales in the U.S. The first assumption was to exit last year with a base of approximately 1,050 patients on therapy. We actually exited the year with a base of over 1,100 patients on therapy. Second, we added over 300 net new patients, well above the average of 200 per year we need. Third, we improved the percentage of paid therapy in the commercially insured part of the business from 7% to 79%. And fourth, We made a modest net annual price increase in the US. In all four of these assumptions, Charlie executed such that we met or exceeded each of these goals. That's great execution and real progress towards our goal. Today, we'll focus our prepared remarks on Orla Deo and the financials. We'll start with Ryan, who will cover the data presented at Quad AI this past weekend. and how many patients on Orla Day are seeing excellent control of their HAE along with the convenience of one's daily dosing. With that, I'll pass it over to Ryan.
spk05: Thanks, John. I've had the privilege during my career to work on several therapies that help change the lives of patients who live with chronic, life-altering diseases. An important lesson I've learned is that long-term data, and particularly evidence from real-world experience, especially in rare disease, are critical to understanding how a treatment can address unmet needs and change the lives of differing patient populations. This is an exciting time for OrlaDeo because after three full years on the market, we are seeing a very consistent picture emerge from the building evidence. The realtor experience and the long-term clinical data are telling a very consistent story on how OrlaDeo can provide meaningful benefits to a variety of HAE patients. We recently published the final analysis of data from the open-label long-term extension portion of the APEX2 study of barotrol stat. The patients who started on blinded barotrol stat, 150 milligrams, and completed the full two years of the study had an average reduction of 90.8% in HAE attacks compared to their baseline rates. But most of us don't measure their attacks in percentages. What's most meaningful to people living with HAE is that they get the chance to live a normal life by minimizing their attack burden and experience meaningful improvements in their everyday quality of life. all while avoiding the unnecessary potential burdens of treatment. Orla Deo treated patients in this long-term study reported rapid and sustained improvements from baseline of 3.3 attacks per month to 0.3 attacks per month after two years, with the median attack rate of zero at month 24. These patients also reported meaningful long-term improvements in quality of life, treatment satisfaction, and an overall safety profile that is very reassuring for people living with this lifelong disease. That kind of change and the sustained low rate of attacks with just one pill once a day is transformative for many patients. These long-term data from our clinical program tell an important part of the story, which is being consistently reinforced by our expanding base of real-world evidence. This past weekend at the Quad AI meeting in Washington, D.C., we presented five posters showing strong real-world evidence with Orlidale in a variety of patients with HAE. What patients are experiencing in the real world is consistent with the two-year clinical data. Patients with type 1 or 2 HAE are reporting long-term median attack rates of around half an attack per month after switching from other prophylactic therapies. By their own account, these patients are having fewer attacks on oral and oral than on their prior therapies. Patients report rapid and sustained reduction in attacks or maintaining attack-free status regardless of whether their baseline monthly attack rate was very high or very low prior to starting on Orlidale. These data on effect, regardless of baseline attack rate, are consistent with evidence we have presented from our clinical trials. Patients diagnosed by their physicians as having HAE with normal C1 inhibitor levels also are reporting rapid and sustained reductions in attacks on Orlidale. And we are seeing similar outside of the United States, particularly in countries like France, where patients can be followed in comprehensive programs with the active involvement of healthcare providers. This real world evidence demonstrating the long-term safety and effectiveness of OrlaDale is exciting. Our team has been hearing the stories of OrlaDale over the past three years, and these data further illustrate why it is such a favorable treatment option for people living with HAE. What is even more exciting is that the data we presented at Quad AI are just the start. We will continue to generate more real world evidence with OrlaDale over the coming years And we look forward to showing again and again how this treatment can help change the lives of patients and families impacted by HAE. I'll now turn it over to Charlie to describe how this emerging evidence is translating to our commercial efforts. Thanks, Ryan.
spk07: As John noted earlier, we recently described how consistent net patient growth of 200 per year for the next several years puts us on track for $800 million in sales in the United States. Entering our fourth year on the market, we are very much on track because we added 321 Orlodeo patients in the US in 2023. The real-world evidence that Ryan described helps explain this growth. Patients would like convenience. There's no doubt about that. But what they demand is efficacy, control of their attacks. The real-world data with Orlodeo clearly demonstrate that patients can have both. efficacy, and convenience, no trade-offs. Our teams have done a very good job of launching Orlodeo, but in the end, patient experience will dictate how far we go. Ryan shared that after switching to Orlodeo from other prophylaxis therapies, patients experienced a median rate of about half an attack per month. What that means for patients is that many or most months are attack-free, and attacks that need to be treated are often less severe. Half an attack per month is also an important benchmark. We do market research with large samples of HAE patients, and we've reported previously at a medical congress that half an attack per month matches the level of attack control reported by patients taking injectable prophylaxis therapies in the real world. This low and consistent rate of attacks on Orlodeo meets patients' expectations because they know from experience that perfect control is unlikely with any product. For many patients, to be able to get that level of control with an oral once-daily therapy is transforming how they live with HAE. We recently conducted an anonymous market research project with a sizable cohort of patients who have experience with Orlodeo, and asked them as part of an exercise to write a letter to Orlodeo describing that experience. Themes such as, you gave me confidence, you changed my life, and I feel like a normal person again were common. The strong evidence from patients also continues to shape prescriber expectations and give them confidence. Our large quarterly surveys of allergists in 2023 showed they consistently expected to grow the proportion of their HAE patients treated with Orladeo by about 30% over the next 12 months. As we noted in our press release today, the number of patients on paid therapy or our long-term free product program also grew by 30% in 2023, tracking with physician predictions. Currently, about 50% of patients on Orladeo have switched from other prophylaxis. But the allergists in our 2023 surveys expect about two-thirds of Orlodeo growth over the next year to come from switches from injectable prophylaxis. By the end of 2023, Orlodeo had been prescribed over 2,500 times in the United States. That means that at least 5,000 diagnosed and treated patients have not yet tried Orlodeo. Over 1,000 US healthcare providers have now prescribed Orlodeo, including over 200 new prescribers in 2023, but clearly there is an opportunity for HAE treaters for many more of their patients, just as our market research predicts. We have way more opportunity in front of us than behind us, and the growing body of evidence about how Orlodeo is changing patients' lives is going to help us get there. I'll pass it to Anthony to describe our financial performance.
spk04: Thanks, Charlie. It was great to see such a strong Q4 and full year 2023 for Orlodea. Not just the revenue performance, but the continued underlying strength in net new patient ads, giving us confidence of achieving between $380 million in global Orlodea revenue this year on our path to peak sales of a billion dollars. You can find our detailed fourth quarter financials in today's earnings press release, and I'll call your attention to a few items. Total revenue for the quarter came in at $93.4 million, 90.9 of which came from Orlodeo and Orlodeo net sales for full year 2023 at $326 million, an increase of 74 million or 30% year over year. Of the 90.9 million of global Orlodeo revenue, 79.4 million came from U.S. sales with the remaining 11.5 or 12.7% coming from ex-U.S., On a full-year basis, U.S. Orlodeo sales contributed $288.4 million of the $326 million global total, with the remaining 37.6% or 11.5% coming from ex-U.S. Operating expenses, not including noncash.com for the quarter, were approximately $119.6 million. Included in this are significant one-time expenses. These include about $5.4 million attributable to the R&D reorganization, including costs related to the reduction in force and the postponement of the expansion of the Discovery Center in Birmingham, Alabama, the $5 million upfront payment we made to Clearside related to our partnership, as well as around $7 million in CMC and other trial costs related to our partnership decision for BCX 10013, all of which explain the increase in OPEX from Q3 of 2023. Operating expenses, not including noncash.com for the full year, came in at $379.5 million, which, when excluding the $5.4 million of restructuring one-time adjustments I mentioned, landed it within our guidance range. We expect that quarterly expenses in 2024 will normalize in the low to mid $90 million range, taking us in line with our full year 2024 guidance of between $365 and $375 million, and essentially flat to 2023. Cash at the end of the year was at $390.8 million, and net cash utilization for the quarter was $8.4 million. In January, we provided guidance on our near-term timeline to achieve profitability. For 2024, we expect that revenue will exceed OPEX, not including noncash.com, and this will result in us generating an operating profit this year. Additionally, with revenue exceeding $350 million, it puts us into a tier whereby the incremental revenue will be more profitable as the blended royalty rate is reduced. In the second half of 2025, we expect to be approaching net income and cash flow positivity on a quarterly basis. And then in 2026, we expect to achieve net income and cash flow positivity on a full year basis. Achieving independence from the capital markets, while we also continue to invest in further expanding our global reach for Orladeo and expanding our label with the pediatric indication, while also further advancing our exciting early stage pipeline puts the company in a very strong position moving forward. Operator, we'll now open it up for Q&A.
spk15: We will now begin the question and answer session. To ask a question, you may press star then 1 on your touchtone phone. If you are using a speaker phone, please pick up your handset before pressing the keys. If at any time your question has been addressed and you would like to withdraw your question, please press star, then two. At this time, we will pause momentarily to assemble our roster. The first question comes from Tuzine Ahmed with Bank of America. Please go ahead.
spk14: Hi, guys. Good morning. Thanks for taking my questions. Can you give us a little bit of color regarding the patients that you were able to add last year? They came, as you said, higher than what you anticipated. Was there a particular profile of patients that was added that you weren't expecting? And in general, do you have a sense of what level of baseline attacks patients have when they are switching in particular? to your drug from another drug? And then I have a follow-up. Thanks.
spk07: Sure. Tazine, there wasn't really a profile that we weren't expecting. Since the beginning of launch, we've been getting patients from all different profiles, as Ryan laid out with some of the data. Excuse me. Sorry. Some of the data that we presented this weekend at Quad AI, regardless of baseline attack rate, regardless of background therapy, patients do really well on Orladeo. Sorry, Kim.
spk01: Do you want to take the rest of that, Ryan?
spk02: Yeah.
spk01: Is there any phenotype? I think what she's asking is, is there a baseline attack rate? Is there any phenotype that we're seeing? Any particular group that's going into... you know, switching to Orladeo.
spk05: Yeah. And I'll call your attention to slide six and slide eight in our deck. Both of these speak to the background or baseline attack rates. And what you'll see here is despite varying attack rates being high or low, patients do very well on Orladeo. Slide eight specifically calls out a baseline attack rate of 1.33 at baseline for those with HAE type 1 or type 2. And, again, those patients did very well, achieving an attack rate of 0.5 at date 540. So they had a rapid and sustained reduction in their attack rates. So, you know, basically, you know, a variety of patients can benefit from Orladeo, regardless of what their baseline attack rate is.
spk01: Yeah, so Tazine, you really can't predict it. So the goal is to get everybody to try it and see if it works for them.
spk14: Okay, yeah. I was more asking about whether it. whether in real life you were seeing something different relative to what you would see in clinical trials. Seems like the answer to that is no. And then maybe just as a follow-up, how are you thinking about discontinuation rates on a go-forward basis? How have they been trending? Any changes from the time that you launched? Thanks.
spk01: So Charlie's alive. I think I can talk again.
spk07: It's my asthma attack. The discontinuation has been really steady in 2023 and the last few years. So still when a patient starts Orladea, we get 60% of those patients to 12 months and then very few discontinuations after that. And I think relating to your earlier questions too, we see the same retention rate regardless of patient's background. So regardless of their attack rates, regardless on whether they're switching from prophylaxis or coming in from acute only, they're all staying on at about that same rate, 60% a year. Okay, thank you.
spk15: The next question comes from Brian Abrahams with RBC Capital Markets. Please go ahead.
spk06: Hey, good morning, guys. Thanks for taking my question. Congrats on the continued progress. I'm curious if we could talk a little bit about your sales and marketing strategy this year relative to last year. do you expect, I guess, continued pull-through from some of the team territory changes that were implemented in 2023? In 2024, what do you expect to be the focus of the additional SG&A investment for this year? And are there any changes to your commercial approach or strategy with an expected greater proportion of the opportunity now coming from the switchers versus those patients who are on-demand only?
spk07: Charlie, you want to take that? Yeah. Hey, Brian. So one of the reasons I do think we did so well last year is we did make those adjustments to the team in the beginning of 2023. By the end of last year, the additional sales folks, the additional patient services, market access that we added, everyone was active and really comfortable in their roles and working well together. And I think that that is a big part of our performance. And then going forward to your question about any changes, the kind of data that, again, that Ryan presented I think is really critical. And we're very focused on getting patients and physicians comfortable with switching from an injectable prophylaxis to Oral-A-Deo is opportunity for patients to really benefit. And I think we're seeing that our customers are starting to understand that. So we'll keep the focus on that messaging.
spk01: And Brian, one thing I'd add, Brian, is that Charlie mentioned was this increasing confidence. And one of the things that we're seeing at Quad AI and other places, we had a standing room only session at Quad AI. And the confidence in the docs is really high. You compare that to a year ago where people were still kind of on the fence. And it's really because they've had experience and they're seeing it work extremely well in patients. So that'll have an effect on them that'll be really positive for Orladeo and for patients.
spk06: Got it. Thanks, John. And maybe just a quick follow-up. It sounds like you've got some visibility to getting to the goal of a paid rate of 85% by the end of the decade. Where do you think you can get the paid rate this year relative to 2023? What's embedded in your guidance and how much potential upset could there be versus your guidance if things go better than expected on that front? And I'll hop back in the queue. Thanks.
spk07: Brian, what we've said before is that that 85% number, yeah, we're very confident we'll get there, but it's going to take us a few years. And so we announced this morning in the press release that we ended last year at a rate of 71.5%. So we'll make some incremental improvements to that, but don't expect any major changes. We're not going to jump straight to 85%. We'll get there probably more in the 2026, 2027 timeframe.
spk06: Got it. Thanks, Charlie. Thanks again.
spk15: The next question comes from Jessica Fay with J.P. Morgan. Please go ahead.
spk02: Hey, guys. Good morning. Thanks for taking my question. Can you just talk about the extent to which your near and long-term top-line expectations for Orlodeo reflect the introduction of less frequently dosed injectables and other orals? Thank you.
spk07: Hi, Jess. We take into account all the introductions of new products, including new injectables and possibly in the future, new orals. And what Jinky Roselli and I described at the last earnings call is that patients, once they're on a therapy and doing well, tend to be really sticky on that therapy. And when patients are doing as well as they are on Oral-Adeo, We don't see them moving to other therapies. The other key part of it is that we have a very differentiated product in a once-daily oral, and that's something that patients and healthcare providers really want. And so a new injectable therapy offers some incremental benefits, but it is not highly differentiated the way Orladeo is.
spk01: Just flip the question around and ask, Why would they go on to another product? What's the incremental benefit? And I think what Charlie presented today and what Ryan presented is patients aren't sacrificing efficacy for convenience. This drug works spectacularly well in certain patients, and it's a once-a-day drug. So what incremental benefit is going to cause them to switch? And we've seen... we're getting switches, you have to have some incremental benefits. So the question is, it can't be efficacy, right? Because if you're controlled on our drug, then you can't do any better. Thank you. You're welcome.
spk15: The next question comes from Lisa Baco with Evercore ISI. Please go ahead.
spk03: Hi, just to follow up on that, I mean, you do have a half an attack rate per month, right, which is one every two months, which is six per year after switching from other prophylaxis. So would that not be like those types of patients, would they not be interested in maybe trying something else? That would just be my like one question, but I actually have other questions beyond that.
spk01: You want to tackle that one? I mean, the bottom line is nobody does better than that. That's kind of the standard. Every drug has breakthrough attacks. And, you know, in that number is a mixture of people that aren't having attacks and some that are. But, Ryan, I don't know if there's anything else to add.
spk05: Yeah, as John alluded to, I mean, you're seeing similar attack control with other injectable therapies. And, you know, we view this not as a tradeoff but a tradeoff because, again, patients don't want just attack control. They want the added conveniences as the quality of life improvements. And, again, we've reported all of that both in our clinical studies as well as in the real-world evidence. So half an attack per month is doing very well. And, again, that doesn't include attack severity, which for some they've shared these are very manageable. So, again, this is a very notable improvement and looks very similar to injectables in terms of attack rate control.
spk01: Yeah, so, Lisa, don't get confused by the numbers of attack rate reduction in a pivotal study because the confidence intervals from those studies overlap. They all work is the bottom line, and they're not perfect. They all have some breakthrough attacks.
spk03: Okay. And have you done any convenience analysis like market research on these sort of like, you know, very long-acting agents? Because it seems like, you know, at some point you might tip the balance between taking an oral pill and frequent injection. I realize that some people don't like injections too, but is there any, I guess, like elasticity there in a way?
spk01: Yeah, no, that's a really good question because we're super paranoid. And one of the things I ask Jinky is, what's the tipping point on frequency of injectable dosing that would make it as attractive as at once daily oral? We haven't found it yet. I mean, we run that research. We haven't found it yet. And so we'll keep looking.
spk05: Sorry to interrupt. I would just add, I think people underestimate the fear of injections that patients experience. And while it can be convenient for some, I think that fear and fatigue of injections can be underestimated, and we hear that continuously from our physicians and from patients as well. So they are seeking convenience as well as that aspect of having a normal life and carrying around a once-a-day oral feels very normal for a lot of patients.
spk03: Okay, great. And then just a quick question from me. Can you kind of go through the math of, like, how many patients you've treated so far? How many patients? like HAU patients are out there and how many more need to try Orlidale given the kind of like stickiness of the product, like, you know, maybe whatever half the patients or so end up like sticking to it long-term to kind of like go through from here to get to that sort of $800 million US number.
spk01: So start with the 7,500 and work backwards.
spk07: Yep. Lisa, the, the, Near the end of my remarks today, I pointed out that there are at least 5,000 patients who have not yet tried Orlodeo. That's based on our previous estimates that there are about 7,500 diagnosed and treated patients. We've had 2,500 prescriptions to date, so there's at least another 5,000 patients. And with what we're hearing from physicians and patients, we expect a lot more trials in that 5,000, so plenty of room to grow.
spk03: Okay, and as you think about what you need to get to that 800 number, is it like half of those that need to try it, or what is the amount?
spk07: That's probably a pretty good estimate. What we need to get is to about 2,000 patients who are sticky at peak, and we are more than halfway there at this point.
spk03: Great. Thank you so much, guys. You're welcome.
spk15: The next question comes from Stacy Koo with TD Cowen. Please go ahead.
spk13: Thanks for taking our questions. So first question is around kind of potential implications with the change in the Medicare Part D redesign due to IRA. So could there be any potential impact to patient volumes with a decrease in the max out-of-pocket spend? And what would be the timing of something like this? So that's one. And then just a follow-up to some of the questions that have been asked. Can you just further characterize your commentary around the clinicians that are prescribing? Are they more academic, more community? Is it really still just that 50% split now? Thanks so much.
spk07: Thanks, Stacey. So on the IRA, particularly next year when the max out-of-pocket shifts to $2,000, we think that will be an advantage for patients in terms of affordability. And very important is the next year that $2,000 can be paid over the course of the year in the 12-month increments. And so we think that that'll increase affordability and likely increase the rate for Orlodeo. Don't think it will really change the volume of patients treated. It's just going to affect the rate. And then as far as clinicians, we see a great mix. Again, we see the academic physicians as well as a lot of community physicians. As I said, over 1,000 healthcare providers have prescribed so far, and that is really distributed very evenly across the deciles of our healthcare provider potential index. And it's been very consistent that way. every quarter. So we're getting both academic and community.
spk13: Understood. And just to follow up, does that mean that you think as the rate improves for kind of the IRA changes, you do think that you'll be able to kind of switch more patients over to paid drugs? Is that a fair way of thinking about it?
spk07: Yes, we do. Next year in 2025 and beyond. Okay.
spk13: Wonderful.
spk15: Thank you. Thanks. The next question comes from Sergey Belenje with Needham & Co. Please go ahead.
spk08: Hi, good morning. Thanks for taking my questions. I guess the first one for Charlie, can you just give a little color on the 1Q seasonality this year? Is it similar to prior years? And then second question, I guess for John and maybe the rest of the team, I think you've all been consistent that you do expect competition from an oral prophylactic by the end of the decade. Just curious your thoughts on an oral on-demand treatment and what impact that could have for the market.
spk07: Thanks. Hey, Serge. I'll start with that. For 1Q, yes, we expect Similar seasonality with the first quarter revenue being down versus Q4. We had a really strong Q4, so we actually think the percentage reduction could be a little bit more this year. So I think 7% or 8% drop from Q4 and probably mid-80s in revenue for Q1.
spk01: And with regard to oral competition, specifically on-demand therapy, I mean, We certainly can't argue that orals are important, and if you have an oral alternative for a breakthrough attack, we think that's great. And so having that as a choice for patients, we think, is just another benefit. And an all-oral option would be fantastic, right, a prophy, and when you have a breakthrough attack, take an oral on demand.
spk10: Great. Thanks. You're welcome.
spk15: As a reminder, if you would like to ask a question, please press star, then 1 to be joined into the question queue. The next question comes from Gina Wang with Barclays. Please go ahead.
spk12: Thank you for taking my questions. I just have one. Regarding the data report, I think if we look at the slide 678, when we look at number of patients, more than two-thirds of patients, I mean the beginning of a patient number and the end of a patient number, it was about one-third of patients continue until the end of data report. So any color you could give regarding the other two-thirds of the patients,
spk01: Yeah, and these, well, maybe I'll let you start, Ryan.
spk05: Yeah, I mean, thanks for the question. You know, these are patients that are, you know, they're reporting, self-reporting their attack rates. And because this is real-world data, there's always limitations in terms of how that is recorded. In some months, patients may not share what their attack rates are, but that doesn't mean they've necessarily come off of therapy. Okay. And all of these patients that you've seen in these slides have completed 540 days of therapy. We're still waiting for some to complete that same timeframe to include them in the analysis.
spk01: Keep somebody in a study for two years is challenging, certainly. And remember, some patients don't do well in our drug. We've got about a 60% retention, and so it's not uncommon to see people not succeed, and you see that in some of these results.
spk07: Just to underline what Ryan said, just to make sure it's really clear, in this real-world evidence, We measure patients based on the length of time that they've been in therapy, and some of them just haven't had the opportunity to reach 540 days because they started at a later time point. So it's a dynamic sample. Of course, some patients do drop out, but this represents how well patients, when they're doing well on Orlodeo, they're doing really well and sticking on therapy.
spk01: That's the point, Gina, is that the patients that do well do really well on drug.
spk12: Okay, great. Thank you.
spk15: The next question comes from Francois Brisbois with Oppenheimer. Please go ahead.
spk11: All right, thanks for taking the question. I was just wondering, in terms of the discontinuation rate, so what leads to this discontinuation rate? Is it that, you know, for those patients that just aren't doing well, or is there any other reason out there? And if they do discontinue, what do they usually end up doing?
spk07: Thanks Francois. The discontinuation rate, there are two main reasons for discontinuation and these won't be surprising. The number one reason is perceived lack of efficacy. So as we've said, no drug is perfect and no one HAE therapy is for everybody. And so that's the number one reason reported. The number two reason is adverse events, specifically gastrointestinal, which is not surprising given given the product label and our clinical trial experience. What we do know is that some patients give up too early. And so part of our messaging is for physicians and others to set expectations that you can have a breakthrough attack. You might have GI events. The GI events tend to go away after a few weeks of therapy for most patients. And so it's important that patients don't give up too early. We actually see in 2023 about 10% of the patients starting Orlodeo were actually restarts. They're people who gave up in the past and came back because they knew that they'd given up too early.
spk01: And Francois, John can send you the slide, but one of the slides we've had in previous decks shows the pattern of discontinuations over two years, and it's flat. So I think now we have a pretty good idea of what that pattern is. And if we've got you for out to a year, we've got you.
spk11: Understood. And then can you just help me understand a little bit the U.S. versus ex-U.S. dynamics in terms of the growth and your assumptions and expectations? Are there challenges, maybe ex-U.S. that aren't happening in the U.S.? Just any color that would be helpful. Thank you.
spk07: Sure. Ex-U.S., first of all, once. The biggest challenge or the biggest time factor is getting market access in an ex-U.S. market. And so that always takes longer, and we have countries rolling on all the time. So a number of countries in Europe, for example, like Germany, U.K., and France, we got market access a few years ago, but we're just now getting market access in others like Spain and Italy. And so that's one factor. Pricing is a lot lower, ex-US, so it takes four to five ex-US patients to add up to one US patient. So our strategy is very much a volume strategy outside the US. And then finally, what we're seeing in the real world, in these countries where we have market access and we've launched, is the same consistent pattern of patient ads, depending on the market. the HA market dynamics. Sometimes that's patients switching from other prophies. Sometimes it's growing the prophylaxis market with a drug like Oral-Adeo. At peak, we expect XUS to equal about $200 million of the billion dollars in sales, and what we see so far gives us confidence that we'll get there.
spk01: And if Texairo is an analog here, Right at the time that the U.S. starts to flatten out, the ex-U.S. continues to grow, so you have overall growth of the brand still. So that's what we're expecting right now.
spk11: Understood. Thank you very much.
spk01: You're welcome.
spk15: The next question comes from Maury Raycroft with Jefferies. Please go ahead.
spk00: Hi. Good morning, and thanks for taking my questions. I just wanted to ask a clarifying question on the seasonality this quarter. Is that for the same reason as in first quarter 23, where there were budget issues with external charities, which increased the number of patients on free drug program? Or what are you seeing this year so far?
spk07: Sure, Maury. That's one of the situations, the Medicare issue. We've got a little bit of insight into that. What I'd say is it's not solved yet. It doesn't seem to be worse than that, but it's not solved. We think next year, as I said earlier, with the IRA rolling in fully, we have expectations that that budget issue will be more solved in 2025. The main reason for the dip in Q1 is the broader percentage of patients getting reauthorizations. And when that happens, we have to drop many patients back temporarily to free product. And then also in the first quarters, it's the highest hit to gross to net because in the commercial market, we're helping pick up patient copays. And the majority of that happens in the first quarter.
spk01: And you'll see a corresponding nice pop in the second quarter when we get those people back to pay.
spk00: Got it. Makes sense. And one other quick question. What proportion of the 321 new patients are on short-term quick start and how long on average does it take to convert these patients to long-term paid patients?
spk07: The 321 was the net growth across the whole year. So what we did say is that we ended the year with 1,104 patients on either paid therapy or long-term free product. There was also a sizable chunk of patients on short-term quick start, new patients coming in. And it usually takes us, we get the product out very quickly. For most patients, we get them to either paid or from free product within about a month.
spk00: Got it. Okay. Thanks for taking my questions.
spk07: You're welcome.
spk15: Your final question today comes from John Wallenby with Citizens. Please go ahead.
spk10: Hi, this is Catherine, on for John. I just have a question about how you're thinking about profitability versus your earlier pipeline, kind of prioritizing those, and then just a question about the data coming. Is it still coming in mid-year for the PNH trial? Thanks.
spk04: Yeah, I think we've been very clear about our path to profitability, very excited to get to the point where we're independent of capital markets. We've been seeing over the past years that convergence of the lines between revenue and OPEX. We continue to see it this year and beyond. So being able to generate an operating profit this year, getting towards both cash positivity and EPS at the end of next year and then achieving it in 2026, I think puts us in a great spot. we do that at the same time as continuing to invest in that early phase pipeline. So the two things coexist and actually the opportunity to be able to invest in, you know, whatever we can do to move as fast as we can in those periods because that early phase pipeline that we generated in or that we announced in November is in fact early phase. puts us in a spot where the expenditure within the next kind of three years is, you know, not as meaningful as it would be when you get them to pivotal trials. So, you know, I think the company's in a great spot, and if there's anything we can do to accelerate, we absolutely will.
spk01: And there's nothing to update on 10.0.13. Nothing's changed on the timeline.
spk10: Thank you.
spk01: You're welcome.
spk15: This concludes our question and answer session. I would like to turn the conference back over to John Stonehouse for any closing remarks.
spk01: Thank you. So one of the things that we're hearing from investors is they have so many things coming at them, and it's hard to keep up with the opportunities to invest in. And if you're in that camp, a question you may want to stop and ask yourself is, how many companies do I have in my portfolio that have a growing product, have a discovery engine that created the growing product, have a pipeline that came from the discovery engine that's going to create another growing product or more, and has an accelerated path to profitability where we're probably going to be cash flow positive or near that in the second half of next year? And if the answer to that is none or too few, and you want to diversify your portfolio, reach out to us. We're happy to get you up to speed on our company and answer any questions you may have. So have a great day, and thanks for your interest in Biochrist.
spk10: The conference has now concluded. Thank you for attending today's presentation.
spk15: You may now disconnect.
