Operator00:00:00Good day, and welcome to the Artalex First Quarter 2024 Earnings Call. All participants will be in listen only mode. After today's presentation, there will be an opportunity to ask questions. Please note this event is being recorded. I would now like to turn the conference over to Caitlin Lowy, Vice President of Corporate Communications and Investor Relations at Artelyx. Operator00:00:29Please go ahead. Speaker 100:00:31Thank you. Good afternoon, and welcome to our Q1 2024 financial results call. During this call, we will refer to the press release issued earlier today, which is available on the Investors section of the company's website atardellis.com. During this call, we will be making forward looking statements that are subject to risks and uncertainties. Our actual results may differ materially from those described. Speaker 100:00:55We encourage you to review the risk factors in our most recent quarterly report on Form 10 Q that was filed today and can be found on our website atardellis.com. While we may elect to update these forward looking statements in the future, we specifically disclaim any obligation to do so even if our views change. Our President and CEO, Mike Robb, will begin today's call with opening remarks and an overview of the company's progress during the Q1 of 2024. Next, Susan Rodriguez, Chief Commercial Officer, will provide an update on the performance of Azrela and Exposa. Justin Rentz, Chief Financial and Operations Officer, will conclude today's prepared remarks with a review of the company's financial performance during the Q1 ended March 31, 2024 before we open the call to questions. Speaker 100:01:39With that, let me pass the call over to Mike. Speaker 200:01:42Good afternoon, everyone, and thank you for joining us on this call. Q1 earnings always seem to come quickly after we report our Q4 results, and yet, as usual, a lot has happened since we last provided you an update. First, EXPOSES performance out of the gate following the launch in November continues at a remarkable pace. This is a first in class product in a therapeutic area that has seen no innovation in decades. The response from the prescribing community clearly demonstrates the significant unmet need among its patient population. Speaker 200:02:14Exposa is an important new option for physicians to help patients whose serum phosphorus remains elevated despite best efforts. All demand indicators are favorable. Prescribers are eager to learn more about exposed blocking mechanism and are working to identify potential candidates for therapy. Like AZERELA, our Delixis is supporting prior authorizations and helping patients take advantage of our affordability programs. Patients are accessing the drug and the feedback is that patients are seeing sustained reductions in their serum phosphorus. Speaker 200:02:47We are focused on ensuring prescribers are aware and educated on exposome and ensuring patients have access to treatment. As you can see by our performance, it's going very well. ISRELA continues to perform strongly, providing an important option to again address a large unmet need among IBS C patients. We believe that this can be a $1,000,000,000 product and on the path to achieving that peak, we expect full year net sales revenue for 2024 to be between $140,000,000 $150,000,000 As I consider the Q1 performance, the underlying demand metrics and fundamentals of the business are robust and continue to demonstrate growth in new and repeat writers and new and refill prescriptions. Our reported revenue reflects demand growth offset by the impact of seasonality which is standard across the industry that we experienced during this Q1. Speaker 200:03:44Importantly, our cash position remains strong resulting from our revenue, the 3rd tranche of debt from our partnership with SLR and thoughtful management of our expenses. We are at an exciting time in our evolution as a company and our top priority is to build upon the growth momentum of Isabella and XFOZA. Now, I will turn the call over to Susan to discuss Q1 performance for both of our products. Susan? Speaker 300:04:11Thank you, Mike. It is great to be here today to discuss the commercial performance for EXPARELA and EXFOZA. Our performance reflects strong execution of our disruptive commercial approach for both 1st in class products, which centers existing treatment options is deemed to be inadequate and enabling patient access and affordability with favorable coverage policies that define the path to access, prior authorization support and patient support programs. Let me begin with Abzrela. Our confidence in this product is driven by the strength of the fundamentals driving IBZRLLA's performance. Speaker 300:04:58HCPs are evolving their treatment practice now that they have expanded treatment options for their IBS C patients following the launch of Idrela. Based on the favorable clinical response they are seeing and confidence in the path to access, HCPs are increasingly identifying patients in need of a novel treatment option. During the Q1, we saw increases across all key demand parameters for the product, including growth in new writers and repeat writers, as well as growth in new prescriptions and refill prescriptions. We are very encouraged by the continued growth of these key demand metrics despite AZERLA being impacted by Q1 seasonality that is commonly seen across the industry linked to insurance plan resets and prior XERLLA dedicated sales force footprint from 64 territories to 124 territories. We experienced a strong response to the job posting, attracting sales talent with extensive GI experience who are motivated and enthusiastic to join the AZERLA sales team and be part of disrupting the IBS C market with an innovative therapy. Speaker 300:06:14Hiring, training and full deployment of this team is on track to be completed by the end of the Q2. This sales force footprint puts us in a strong position to capitalize on the promotion sensitivity we have seen across our high riding HCP targets to further drive increases in new riders as well as drive expanded use across our growing rider base who are continuously broadening their view of patients who are candidates for AZRELA. The fundamental drivers behind AZRELA are strong and we anticipate continued quarter over quarter growth with our expectations for the 2024 performance consistent with our stated guidance. Turning to EXFOZA. We are extremely pleased with the nephrology community's response to this 1st in class phosphate absorption inhibitor. Speaker 300:07:02It is clear that patients have been in need of a new option to manage their phosphorus when binders are insufficient or not well tolerated. Our dedicated nephrology sales team, comprehensive blocking messaging campaign, speaker promotional programs and omnichannel initiatives are driving high interest and early uptake of EXFOZA. Nephrologists are responding favorably to the novel blocking mechanism and clinical data profile, are pleased with their early clinical experience, encouraged by the defined coverage policies and increasingly integrating this novel blocking mechanism product into the therapeutic regimen for their patients. The feedback we regularly receive from the field is that physicians are seeing that their EXPOSA treated patients, many of whom have been continuously outside of target ranges, are reflecting consistent improvement in serum phosphorus levels and that these levels are being maintained. We are also hearing that patients are responding favorably to the dosing profile and that HCPs are pleased with the flexibility they have in adapting the patient's treatment regimen, where they can add exposa to the patient's existing binder regimen or they can add Exposa and reduce the patient's binder regimen or they can add Exposa and fully discontinue the patient's binder regimen. Speaker 300:08:25HCPs are adopting Exposa and are adapting regimens based on the needs of the patients. We are very pleased with the $15,200,000 in sales we reported for Exposa during the Q1. This performance is consistent with the uptake indicators we are seeing in the field. Our sales force is experiencing highly engaged meaningful discussions with our target HCPs who are eager to learn about EXFOZA. Nephrology HCPs are rapidly identifying patients who they believe can benefit from therapy, reporting to us that they may have many patients outside of target ranges despite treatment with binders or are intolerant of binder therapy. Speaker 300:09:05HCPs are pleased with the clinical response they are seeing and patients are responding favorably to the treatment experience. Coverage policies are being defined that outline a path to access via prior authorization, attesting to the fact that the patient has been treated with binders and inadequately responding or unable to tolerate the therapy. HCPs are seeing that when prior authorizations are submitted for patients meeting the criteria, patients are gaining access to expoza. Nephrology HCPs and their office staff are responding favorably to our specialty pharmacy distribution network as well as to our comprehensive patient services offering, Ardellix Assist, that further enable patient access through prior authorization support and patient engagement with the affordability programs available to them. Our own internal metrics are supported by external research conducted by Spirex, who is tracking the launch of XPOSA. Speaker 300:10:03According to the April 2024 LaunchDynamics report, nearly all of the 77 surveyed nephrologists, 98% rate exposa as an advance over currently available hyperphosphatemia therapies. In addition, 56% of the surveyed nephrologists reported using exposa and of those, again, 98% report satisfaction with treatment. The research demonstrates that awareness is high among the nephrology community, interest and intent to adopt is high and satisfaction with the treatment is high among users. We will continue to build upon our launch momentum, capitalizing on the high nephrology awareness of the number of patients that are in need of a new treatment option despite treatment with binders and their intent to adopt EXFOZA for these patients. Our go to market strategy is working. Speaker 300:10:56We have established a strong presence in nephrology offices across the country and HCPs are responding favorably to the novel blocking mechanism and clinical data profile. They are identifying patients that could benefit from exposa therapy and with coverage policies in place, patients are gaining access and responding favorably to treatment. We are pleased with the performance thus far and are focused on continuing this growth momentum. We have several exciting months ahead as we will have strong commercial and clinical presence across key annual medical conferences for both Ibsrela and EXPOSA, where we will have the opportunity to present more clinical trial data on our products, connect with the prescribing community and deepen our relationship with patients. I look forward to continuing to share updates with you in the future. Speaker 300:11:43With that, I will hand it to Justin. Speaker 400:11:47Thank you, Susan. I'm very pleased to be with you today to discuss the Q1 performance we reported, which included meaningful progress towards our Xrela net sales revenue guidance, a strong launch of XPOSA, careful management of our finances and a strong cash position. Let's start with revenue. As you saw in this afternoon's release, we reported significant year over year growth bringing our total Q1 product related revenue to $45,600,000 compared to $11,400,000 in the Q1 of 2023. Net product sales revenue for IBZRILLA was $28,400,000 during the Q1 of 2024, more than doubling the $11,400,000 in revenue we reported during the same period in 2023 and a 1% quarter over quarter growth compared to the Q4 of last year. Speaker 400:12:41Volume demand grew for RIBZRILLA during the Q1, which was offset by deductions associated with the reset of annual prescription drug plans. Most notably, this was related to our commercial co pay program. The impact of the commercial co pay program is most significant in the Q1 when most commercial healthcare plans reset and patients have higher out of pocket requirements. As patients fill prescriptions throughout the year and begin meeting their deductible requirements, our expenses related to the commercial co pay program decline. Our gross to net deduction for Imperella during the Q1 was in line with our expectations at 33.5% and comparable to the 33.7% we saw in the Q1 of 2023. Speaker 400:13:28We expect this percentage to improve as the year progresses as it did last year. In addition, we saw the anticipated impact of the prior authorization renewal process that occurs at the start of the calendar year for many healthcare plans. The strong demand and expected improvement in gross to net deductions reinforced our confidence in the ongoing performance of Idrela. As such, we continue to expect that full year U. S. Speaker 400:13:55Idrela net product sales revenue will be between $140,000,000 $150,000,000 Exposa had an exceptional first full quarter performance as we are reporting $15,200,000 in net sales revenue driven by the meaningful demand for this product. Our gross to net deduction came in favorably for XPOSA at 23.8%. As we progress into the launch of XPOSA and learn more about the patient mix that drives the associated gross to net deduction, we will share more. In addition, we had $2,500,000 in combined licensing and product supplier revenue. We are very pleased with our top line results during the quarter, which demonstrated the growth momentum Mike and Susan both spoke to. Speaker 400:14:42At the same time, we continue to be thoughtful on how we manage our expenses. Research and development expenses were $10,600,000 compared to $9,100,000 during the Q1 of 2023. Selling, general and administrative expenses were $53,000,000 for the Q1 compared to $26,800,000 for the same period of 2023. The increase was related to watch activities for XFOZA as well as continued investments to grow Ibsrela, which we made throughout last year. Importantly, our costs were comparable to our spending in the Q4 of 2023. Speaker 400:15:19We expect to complete the current expansion of the Ibsrella sales force that Susan previously mentioned by the end of the Q2. Substantial top line growth combined with thoughtful cost management resulted in a net loss of approximately $26,500,000 or $0.11 per share in the Q1 of 2024 compared to a net loss of $26,800,000 or $0.13 per share in the same period of 2023. The net loss for the Q1 of 2024 included $9,300,000 in combined non cash expenses from share based compensation and non cash interest expense related to the sale of future royalties. As of March 31, 2024, we had total cash, cash equivalents and short term investments of $202,600,000 as compared to $184,300,000 at the end of 2023. This includes $49,800,000 in net proceeds that we drew in March from our term loan agreement with SLR Capital. Speaker 400:16:27We are very pleased with our performance during the Q1, driving top line growth across all reported revenue lines, planning for success, investing in our supply chain, managing our operating expenses and strengthening our cash position. We will continue to be thoughtful with how we deploy capital while focusing on maximizing shareholder value. Speaker 200:16:47With that, I'll turn it back to Mike. Thanks, Justin. I hope that what you took away from our performance during the Q1 is that one, we continue to have high expectations for Xrella, including $140,000,000 to $150,000,000 in net sales revenue this year and on the path to at least 10% market share and $1,000,000,000 in annual revenue. 2, EXPOSA's launch progress is exceptional and it is already beginning to disrupt the hyperphosphatemia market where there remains significant unmet needs among patients. And finally, we're in a strong cash position to invest in growth. Speaker 200:17:25We have a lot of important work ahead of us and we have the team in place who is able to deliver. I look forward to sharing our progress with you over the coming quarters. And I will now open the call to questions. Operator? Operator00:17:39Thank The first question comes from Chris Raymond with Piper Sandler. Please go ahead. Speaker 500:18:12Hey, thanks and congrats on the great success here with Exposa. Just maybe one question on that and a follow-up as well. So I know you guys are early in the launch and you've already established sort of a cadence here for guidance after having a number of quarters that you've set with Abbrella. But just the magnitude of the speed is obviously more than anybody expected. Can you provide maybe any sort of color here? Speaker 500:18:42I think everybody sees the script data and if folks were following that, they're even surprised. Those who've been following the script data closely are surprised by the number. Any sort of color in terms of the uptake in what we should be thinking in terms of the implications for the next several quarters, couple of quarters anyway? And then maybe the follow-up is, I know Mike you're not in the business of predicting legislation, but in the absence of sort of any progress in terms of pushing the phosphate binders into the bundle, pushing that off. At what point do you start maybe planning for that as a reality? Speaker 500:19:27Thanks. Speaker 200:19:29Yes. So Chris, thank you for the questions. I guess first of all, I hope by now you can tell that we're not quitters and that we see what we're doing for patients and the uptake that we see with EXPOSA is and has been absolutely worth the fight that we're fighting. I think as you see with what we've done with Intrela, these IVF C patients as well deserve the attention that we're giving them. What you saw with Xarel is we need and we expect to have roughly 4 quarters under our belts before we give guidance. Speaker 200:19:59We don't want to get over our skis. We are excited and thrilled by this performance. The anticipation for the drug out there, the enthusiasm, our ABDs are staying in the field is remarkable. The ability that we have in helping people through the prior authorization process through our dialysis is working extraordinarily well based on so many learnings that we got through with AZERLA. So although I would like to give you a clear answer on both of those, I'm sorry. Speaker 200:20:25I'm sure you understand that I can't. Got it. Thanks. Thank you for trying. Operator00:20:36The next question comes from Yigal with Citi. Please go ahead. Speaker 600:20:41Great. Hi, Mike and Susan and Justin and team. Thank you so much and congrats as well on a very strong launch. Susan, I just had a few questions on the commercial franchise. Regarding AZERLA, can you comment the percent that were new writers versus repeat writers in the quarter? Speaker 600:21:00And then with almost doubling in the territories, how do you expect that to scale in terms of the size of the base of the go and get them to go and ones where you can add and then reduce the binder and then even add EXFOZA and potentially remove the binder altogether. Do you have any anecdotal or early evidence or data to discuss sort of roughly what percent fall into each of those three scenarios? Thank you. Speaker 300:21:36Thanks, Yigal. Thanks for the question. In terms of the new and repeat writing, we have not disclosed the specifics in terms of those percentages. But what I can tell you that's a really important metric to track is just the persistence of new writers being generated weekly, monthly, quarterly. And what we're seeing since launch is that this has been persistent with new writers being generated constantly on a weekly, monthly and quarterly basis. Speaker 300:22:07So seeing that persist really gives us great confidence in the momentum and our guidance for this year. In terms of repeat writing, what's important to note there is that now that we're several quarters into launch, we have the data to show that new writers write again. So we're seeing that repeat writing is also persistent. Where the growth opportunity is, is in continuing to drive that new writer growth, but then also amongst that growing writer base, really growing depth of writing. So these repeat writers could write more often and for more patients. Speaker 300:22:43And what our sales force is executing on is really driving that broader view based on the foundation of positive experience they've had to date of patients that now really need to be considered as candidates for XERLYNXROLA because they do have persistent symptoms, have been tried on other things and now physicians have seen that there is a path to access and that patients are responding well. So they're broadening their view on potential candidates and that's really an important growth opportunity for us as well. In terms of the sales force impact, that's exactly why we believed it was critical to continue to invest in our sales force footprint because our experience to date shows that the space is quite promotion sensitive. So the more we call on doctors, the more they write Idrela. We see that relationship, the more they engage in all of our omnichannel initiatives and in our programs, the more Xarela they write. Speaker 300:23:34So expanding our footprint from 64 to 124 really gives us an opportunity to get those, get into those HCP offices more frequently to continue to drive, that expanded writing and really capitalizing on the fact that they are broadening their view on patients who are candidates for exposome and at the same time can also continue to penetrate our target space and generate new writers. So really being able to execute to achieve both. Speaker 600:24:05Okay, great. And then if you could comment on the exposer question, if you have any data there regarding the way it's bucketing, reducing the binder versus Speaker 300:24:16Yes. Not specifically from a percentage standpoint, Yigal, but what we're hearing persistently is that all nephrologists in general, nephrologists are just commenting on the flexibility. And that's what's really exciting because that means that that patient group that they identify that they believe is inadequately managed on binders or don't tolerate binders, they see exposa because of its complementary MOA blocking mechanism of action as a drug that that patient could benefit from. And they don't have an in going concern around how it gets integrated because they can be flexible on initiating therapy and then perhaps some of them are initiating, tracking and then taking them off, you know, some of the binders. Some of them just cut the binders right away. Speaker 300:25:01Some of the time they just eliminated entirely, as I mentioned in my narrative. So what we hear more is that each doctor is actually using the drug with this level of flexibility and that they see that as a way to really be able to realize the benefits of novel mechanism exposure across their patients that they see are inadequately managed. Speaker 200:25:24And Yigal, it's Mike. Just one additional comment with that is, I think as we spoke of earlier in other calls is you never had multiple mechanisms like you do with so many other diseases to manage what the drugs are trying to address. It's not going to be a static ratio in any given patient. There's going to be an interim intra patient variability depending upon their serum phosphorus. There's now flexibility and tools for these physicians to finally get phosphorus in the target range that they're looking for. Speaker 200:25:52So I think that's going to evolve. And as we understand that better in the coming quarters, we'll certainly share it. Speaker 600:25:59Great. Thank you very much. Operator00:26:04The next question comes from Louise Chen with Cantor. Please go ahead. Speaker 700:26:10Hi, congratulations on all the progress this quarter and thank you for taking my questions here. So first question I wanted to ask you about was Excoza and the $15,200,000 is all demand sales or is any stocking in there? And secondly, just back on this Buddy Carter bill, if it doesn't move through, then is that $1,000,000,000 of peak sales you have for IVYTHRELA at risk or that is regardless of whether or not buddy Carter happens? Thank you. Speaker 200:26:38Yes. I mean there are 2 different product lines in different patient population. So our guidance with INZRILLA is independent of that. But thanks for asking that. As it relates to stocking, let me ask Justin to address that. Speaker 400:26:52Yes. Thank you, Elyse. It has been really a just in time, if you will, approach with EXPOSIT. So through our network, we've seen very low inventory rates since launch in November. So I would say there's absolutely demand of the patients and not at all any stocking, very limited to roughly between 1 2 weeks at max in the channel. Speaker 200:27:39Congrats on the strong early EXFOZA launch. Two quick questions for me. At this point, I was wondering what the breakdown is looking like so far between patients getting access to EXFOZA through Medicare versus non Medicare? And then comparing the how much of EXFOZA's Strongstar are you attributing to differences in market dynamics versus differences in your commercialization strategy? In other words, is your commercialization strategy for EXFOZA markedly different from that of the early Xarel launch or is the main driver more related to differences and things like unmet need, patient exit rate, etcetera? Speaker 200:28:13Yes, Ryan, thank you for the question. The easy answer is, of course, it's our very, very unique and disruptive commercialization approach. No kidding is I think what we do here and Susan can address it in greater detail. It truly is one about having really good drugs that are making a difference for these patients. Having a commercial team that knows how to communicate that from the omnichannel initiatives and remarkable sales team with feet on the ground, talking to physicians about what these drugs can do for their patients, because these drugs work. Speaker 200:28:45Susan? Yes. Speaker 300:28:47So I would say exactly, to Mike's point, our go to market strategy, actually there are really very important parallels between AZERLA and EXPOSA in the novel MOA and the fact that there's limited options and the fact that there's patients in need of novel options. So where I see where what's an important distinction is that for EXPOSA, we went into the market with a very, very ingoing high level of awareness of exposa across the nephrology target base, and high interest and intent to adopt and high level of awareness on the range of the patients that they see that they have challenges in managing serum phosphorus on binder therapy. So I think there was a higher level of market awareness about both the product and the unmet need. Whereas with EBSRELA, while it's a parallel situation where patients have limited options and are inadequately managed and in need of a novel option, in our go to market approach, it's really our promotion and our education on our target base that really got them to begin to identify, wow, yes, patients are inadequately managed. We never had another option. Speaker 300:29:55Now that we have another option, we're increasingly identifying these patients. We're actually engaging in dialogue with these patients and now we're expanding the way we treat and using IBZRLLA for those patients and adequately managed. So there was a little bit more market need education required on the IBZRLLA side. And those would be the only differences. Path to access is the same and the coverage policies as they're being defined have also been favorable on both sides. Speaker 200:30:26Got it. And then on the Medicare versus non Medicare breakdown for the Q1? Yes, Susan? Speaker 300:30:33Yes. Thank you, Mike. Yes, so right now it's actually really interesting being on the market now for a full quarter that we can see from our IQVIA data what the percent mix is for the expoza prescription and, on average between 55% 60% is Medicare and the remainder is non Medicare. Speaker 200:30:57Got it. Thank you very much. Thanks, Ryan. Operator00:31:02The next question comes from Dennis Ding with Jefferies. Please go ahead. Speaker 800:31:09Hey, guys. Congrats on the solid quarter. A few questions for me, if I may. On gross to net for Xposa, this was definitely better than what people expected in the Q1. So how does this evolve through the year? Speaker 800:31:23And we should use the 23% as the new base going forward? And then secondly, I want to take another stab at this question, but on HR 5074, if the bill is to be signed into law in the first half of twenty twenty five, Exposa would need to go into TDAPA. But then if the bill gets signed, XPOSA would need to come back out of TDAPA. Can you perhaps shed some light on that process and some of the logistics surrounding that? Thank you. Speaker 200:31:59Hey, Dennis. Yes, let me just direct address that quickly. Currently, I think as we've said, our intent is to enter Dada, I think the specifics of what you're just describing, that's going to play out over time. But our current intent is to go through the process. And as we hope and the work that we're doing and what Buddy Carter is doing and others on the hill is understanding how important this medicine is for patients. Speaker 200:32:23This is good policy. This is the right thing to do to ensure that patients get access to a drug that's already beginning to make the difference in many, many lives of dialysis patients. So the work continues and the specifics about how things come in and out based upon these next 6 months or more, we'll get that to you as we also learn. And Justin, if you address the gross to net. Speaker 400:32:46Thanks, Mike. Yes, Dennis, in the Q1, Expose's gross to net deduction was 23.8%. It obviously is very early in the launch and also the Q1 of the calendar year. So as Susan articulated, our Medicare and non Medicare split is around 55% to 60% Medicare and the rest non Medicare. We're still warning the patient mix. Speaker 400:33:09This is going to drive the gross to net ratio through the course of the year. So as a reminder, like I said, it's our 1st full quarter. We're currently estimating that maybe it will slightly increase over the next few quarters. But in general, we believe for the rest of this year, it will be in the mid-20s range. And we will obviously comment more closely if we have greater clarity. Speaker 400:33:39Got it. Operator00:33:45The next question comes from a Ruana Ruiz with Leerink Partners. Please go ahead. Speaker 900:33:52Great. Afternoon, everyone. One for EXPOSA. Could you talk a bit about what the early adopter patients look like in terms of their main features and what's really encouraging physicians to find them and identify them as optimal candidates for EXFOZA? Speaker 200:34:10Yes. I'll ask Susan to address it. But the realities are they're not that hard to find. When we know up to patients are out of range, and they've been waiting for something like this. So it isn't that you have to seek and find, it's you should have asked the question, if you have patients above the answer is of course, yes. Speaker 200:34:30And then we move forward. Susan, sorry, I took the Speaker 300:34:34Yes. No, no, you're absolutely right. But I think in terms of I appreciate your question on who are these early patients we're getting. And I think to Mike's point, first of all, important to know that these phosphorus levels are tracked very closely. So nephrologists have like an ongoing understanding of their patient base and where their phosphoruses are. Speaker 300:34:54So what we're seeing in terms of the patients that are being initiated on exposa right away are those that the nephrologists had in mind that they know historically they've really had challenges in keeping them within target ranges. That's who we're getting now. And what's really important as we continue to execute is now that the EXPOSA is available, to really make sure that the nephrologist begins to adapt their behavior and turn to EXPOSA, when possible, looking at their patients that are outside of target ranges. Speaker 900:35:31Got it. Thanks. Operator00:35:36The next question comes from Laura Chico with Wedbush. Please go ahead. Speaker 900:35:41Hey guys, good afternoon. Thanks very much for taking the questions. Just 2 for me. First on AZREA, what needs to happen to hit the high end of the guidance range now for 2024? And then I just wanted to follow-up on EXPOSA, the conversation around the current Medicare Medicaid mix. Speaker 900:36:00Does that is that where you're projecting at a steady state level? You remain kind of a roughly even split between Medicare and non Medicare patients. And I'm just kind of thinking ahead in terms of revenue that might be more exposed to a TDAPA environment versus not. If you could just share any color in terms of where you see that payer mix split ending up over time, that'd be helpful. Thank you. Speaker 200:36:24Yes. I mean, just briefly address the Isabella question is, it's execution. And everything that we have been doing is what we need to continue doing. The expanded footprint certainly is going to be a benefit as we said trained in the field by the end of the quarter. So that's certainly a big part of it too, but it's execution. Speaker 200:36:43The patients are there, they're waiting and when you ask the right questions, the physicians identify them and we help them go through the prior authorization process. Susan, you want to address the exposure question? Speaker 300:36:56Yes, sure. So I think just as anything regarding exposure at this moment, only having 1 full quarter under our belt. It's hard to predict, Laura. I don't want to give you the impression that this is exactly steady state. However, it is not unexpected when you just understanding the patient mix in the dialysis setting and the mix that we've seen even for the IQVIA data for the binder therapies, this is not unexpected. Speaker 300:37:26But we need a few more quarters before we can tell you for certain. One thing that's important is just understanding that the coverage policies have been defined across all the payer segments. So, and I think that's really what's driving the ultimate outcome in terms of the profile. So that is established and will be consistent as we move into this as we proceed through this quarter and going forward since we have nice coverage policies in place across all those segments. Speaker 900:37:56Thanks very much. Speaker 200:37:59Thanks, Lauren. Operator00:38:02The next question comes from Joseph Thomey with TD Cowen. Please go ahead. Speaker 600:38:09Cohen. Congrats on the strong launch. Maybe on EXPOSA, can you give us a little bit of idea of the authorization process from a physician writing a script to actually getting the drug? And then second, Mike, you mentioned the cash balance. Maybe what's your appetite to invest in R and D either internally in the pipeline or maybe go externally and bring something in? Speaker 600:38:40Thanks. Speaker 200:38:41Let me address both the first and last question is, it's early days for us to be sharing what's on the patient assistance program. So we're going to wait until we've got more experience under our belts with that. And as you saw just under a month and a half ago, we hired Mike Kelleher as our Executive Vice President of Corporate Development Strategy. That should be the signal to your question, our willingness to invest in pipeline opportunities, whether it's organic development or opportunities we may find outside. As I think what we are demonstrating is that the approach that we take to commercialization of drugs is clearly unique. Speaker 200:39:20Our ability to attract remarkable performers in the field, I think is evidenced what you see in both ISRELA and EXPOSA performance. So leveraging that and bringing Mike on board certainly is a big part of us going in that direction. Speaker 600:39:38Great. Thanks. Operator00:39:42The next question comes from Ed Arce with H. C. Wainwright. Please go ahead. Speaker 1000:39:49Hi, everyone. This is Thomas Yip asking a couple of questions for Ed. Congrats on the strong early traction with exposure. Perhaps first question, can you discuss how many patients are on exposure therapy to date and among these patients, what's the split between GI, gastro and then PCP subscribers? And then I have a follow-up question as well. Speaker 200:40:14Yes. It's a little bit hard to hear the question, but I think you're asking about the split of patients in GIs versus PCPs. I think as Susan has spoken about our targets, it's high writing GIs and high writing HCPs who act as other GIs in that big practices. I don't know, Susan, if you want to add anything more to that? Speaker 300:40:34Yes, exactly. So we identify our target audience is 9,000 HCPs that account for 50% of the total IBS C indicated market. So even though so many doctors write IBS C scripts, the opportunity of really targeting this concentrated group that accounts for 50% is really what drives this Abbrella opportunity for us. And as Mike mentioned, what we find is that there really isn't a distinction between PCP and a GI. What we have is the high writing GIs and then we have high writing non GIs that actually behave like GIs and just decide to take an interest in treating IBS C and using the IBS C C indicated drugs to manage their patients. Speaker 300:41:20So it's really not a distinction that's relevant in our go to market approach. Speaker 1000:41:29Got it. And also, can you discuss how many patients are on exposure for efficacy data and also the script data, it can be a reasonable indicator of underlying demand of growth? Speaker 200:41:46I think you're asking how many people are on 60 day versus 30 day scripts. I think again it's early days for us to be sharing that kind of information. Operator00:42:03The next question comes from Matt Kaplan with Ladenburg Thalmann. Please go ahead. Speaker 1100:42:10Hey, guys. Thanks for taking the question. And nice out of the gate launch for Eksoza. Congrats there. Just want to dig in a little bit more to Eksoza's performance during the quarter. Speaker 1100:42:23I guess what that could mean for demand in 2024 and beyond. But I guess especially given the high levels of interest you're seeing in the SPHERIC survey. Were these initial doctors kind of adopters that really take on new therapies? And then will it be more difficult to get additional doctors down the line because these are the early on new therapy interest there? Speaker 200:43:00A quick comment and then I'll ask Susan to address in more detail is nephrologists have been trying their entire careers with these patients to get their serum phosphorus levels in check. And they have been woefully unable to with a single mechanism of action of binders irrespective of the type of binders that it is. Patients don't want to take that amount of material, low phospho suits are unpalatable, it's really a difficult life. And when a new mechanism of action like this comes in and as Susan spoke in her opening statement about how this is being utilized along exactly what the votes were in our AdCom is really heartening. And I think physicians see the opportunity to finally have a tool in their toolkit that may help their patients get into the target range that they've been trying to do. Speaker 200:43:46And as Susan said also in our opening comments that we are hearing from patients and from physicians that these effects are sustained. That's heartening and extraordinarily rewarding that we're going to have that kind of impact on patients. It is early days. You always are going to have early doctors, right? That's not an uncommon phenomenon. Speaker 200:44:06But the difference here is there is not one nephrologist out there that has not struggled with nor one patient out there that has not struggled with how to manage their serum phosphorus. Susan, anything to add? Speaker 300:44:18Yes. I would just say the SPIREX data did report a 56% user base and that's data that was generated in April. So and what we're seeing in the field is that nephrologists really want to spend time with our sales team. We're getting in to these offices. They're learning about it and they do have patients in mind, once they are detailed on EXFOZA. Speaker 300:44:40So I think it's more around it's not around an early adopter profile as much as every doctor to Mike's point has been managing this challenge of getting these phosphorus levels within target ranges with the limited options they have and now are very open to incorporating EXPOSA into the treatment regimen to try to do better. So I think that's pretty common across all nephrologists. Where it's going to be important to continue to move the uptake is to expand their thinking where it's not just that patient that they've always had in mind been so challenging. But now that you have a new tool, as you see these phosphors every month, don't wait for multiple reads or try to make everything work for them on diet or other things, the things that they've struggled with. Now they should treat these patients because of the expanded treatment armamentarium they have with exposos. Speaker 300:45:32So that's what's going to be important is just moving beyond that first cohort of patients that they clearly were waiting for something new and now adapting their practice to having blocking mechanism drug like exposa. Speaker 1100:45:48Thanks guys. That's really helpful. Operator00:45:52This concludes our question and answer session. I would like to turn the conference back over to President and CEO, Mike Raab for any closing remarks. Speaker 200:46:02Thank you everyone for joining us this evening, including our investors who've been on this journey with us, the employees who drive our success, our partners who support us and the patients that we serve. With that, we can close the call.

There are 12 speakers on the call. Operator00:00:00Good day, and welcome to the Artalex First Quarter 2024 Earnings Call. All participants will be in listen only mode. After today's presentation, there will be an opportunity to ask questions. Please note this event is being recorded. I would now like to turn the conference over to Caitlin Lowy, Vice President of Corporate Communications and Investor Relations at Artelyx. Operator00:00:29Please go ahead. Speaker 100:00:31Thank you. Good afternoon, and welcome to our Q1 2024 financial results call. During this call, we will refer to the press release issued earlier today, which is available on the Investors section of the company's website atardellis.com. During this call, we will be making forward looking statements that are subject to risks and uncertainties. Our actual results may differ materially from those described. Speaker 100:00:55We encourage you to review the risk factors in our most recent quarterly report on Form 10 Q that was filed today and can be found on our website atardellis.com. While we may elect to update these forward looking statements in the future, we specifically disclaim any obligation to do so even if our views change. Our President and CEO, Mike Robb, will begin today's call with opening remarks and an overview of the company's progress during the Q1 of 2024. Next, Susan Rodriguez, Chief Commercial Officer, will provide an update on the performance of Azrela and Exposa. Justin Rentz, Chief Financial and Operations Officer, will conclude today's prepared remarks with a review of the company's financial performance during the Q1 ended March 31, 2024 before we open the call to questions. Speaker 100:01:39With that, let me pass the call over to Mike. Speaker 200:01:42Good afternoon, everyone, and thank you for joining us on this call. Q1 earnings always seem to come quickly after we report our Q4 results, and yet, as usual, a lot has happened since we last provided you an update. First, EXPOSES performance out of the gate following the launch in November continues at a remarkable pace. This is a first in class product in a therapeutic area that has seen no innovation in decades. The response from the prescribing community clearly demonstrates the significant unmet need among its patient population. Speaker 200:02:14Exposa is an important new option for physicians to help patients whose serum phosphorus remains elevated despite best efforts. All demand indicators are favorable. Prescribers are eager to learn more about exposed blocking mechanism and are working to identify potential candidates for therapy. Like AZERELA, our Delixis is supporting prior authorizations and helping patients take advantage of our affordability programs. Patients are accessing the drug and the feedback is that patients are seeing sustained reductions in their serum phosphorus. Speaker 200:02:47We are focused on ensuring prescribers are aware and educated on exposome and ensuring patients have access to treatment. As you can see by our performance, it's going very well. ISRELA continues to perform strongly, providing an important option to again address a large unmet need among IBS C patients. We believe that this can be a $1,000,000,000 product and on the path to achieving that peak, we expect full year net sales revenue for 2024 to be between $140,000,000 $150,000,000 As I consider the Q1 performance, the underlying demand metrics and fundamentals of the business are robust and continue to demonstrate growth in new and repeat writers and new and refill prescriptions. Our reported revenue reflects demand growth offset by the impact of seasonality which is standard across the industry that we experienced during this Q1. Speaker 200:03:44Importantly, our cash position remains strong resulting from our revenue, the 3rd tranche of debt from our partnership with SLR and thoughtful management of our expenses. We are at an exciting time in our evolution as a company and our top priority is to build upon the growth momentum of Isabella and XFOZA. Now, I will turn the call over to Susan to discuss Q1 performance for both of our products. Susan? Speaker 300:04:11Thank you, Mike. It is great to be here today to discuss the commercial performance for EXPARELA and EXFOZA. Our performance reflects strong execution of our disruptive commercial approach for both 1st in class products, which centers existing treatment options is deemed to be inadequate and enabling patient access and affordability with favorable coverage policies that define the path to access, prior authorization support and patient support programs. Let me begin with Abzrela. Our confidence in this product is driven by the strength of the fundamentals driving IBZRLLA's performance. Speaker 300:04:58HCPs are evolving their treatment practice now that they have expanded treatment options for their IBS C patients following the launch of Idrela. Based on the favorable clinical response they are seeing and confidence in the path to access, HCPs are increasingly identifying patients in need of a novel treatment option. During the Q1, we saw increases across all key demand parameters for the product, including growth in new writers and repeat writers, as well as growth in new prescriptions and refill prescriptions. We are very encouraged by the continued growth of these key demand metrics despite AZERLA being impacted by Q1 seasonality that is commonly seen across the industry linked to insurance plan resets and prior XERLLA dedicated sales force footprint from 64 territories to 124 territories. We experienced a strong response to the job posting, attracting sales talent with extensive GI experience who are motivated and enthusiastic to join the AZERLA sales team and be part of disrupting the IBS C market with an innovative therapy. Speaker 300:06:14Hiring, training and full deployment of this team is on track to be completed by the end of the Q2. This sales force footprint puts us in a strong position to capitalize on the promotion sensitivity we have seen across our high riding HCP targets to further drive increases in new riders as well as drive expanded use across our growing rider base who are continuously broadening their view of patients who are candidates for AZRELA. The fundamental drivers behind AZRELA are strong and we anticipate continued quarter over quarter growth with our expectations for the 2024 performance consistent with our stated guidance. Turning to EXFOZA. We are extremely pleased with the nephrology community's response to this 1st in class phosphate absorption inhibitor. Speaker 300:07:02It is clear that patients have been in need of a new option to manage their phosphorus when binders are insufficient or not well tolerated. Our dedicated nephrology sales team, comprehensive blocking messaging campaign, speaker promotional programs and omnichannel initiatives are driving high interest and early uptake of EXFOZA. Nephrologists are responding favorably to the novel blocking mechanism and clinical data profile, are pleased with their early clinical experience, encouraged by the defined coverage policies and increasingly integrating this novel blocking mechanism product into the therapeutic regimen for their patients. The feedback we regularly receive from the field is that physicians are seeing that their EXPOSA treated patients, many of whom have been continuously outside of target ranges, are reflecting consistent improvement in serum phosphorus levels and that these levels are being maintained. We are also hearing that patients are responding favorably to the dosing profile and that HCPs are pleased with the flexibility they have in adapting the patient's treatment regimen, where they can add exposa to the patient's existing binder regimen or they can add Exposa and reduce the patient's binder regimen or they can add Exposa and fully discontinue the patient's binder regimen. Speaker 300:08:25HCPs are adopting Exposa and are adapting regimens based on the needs of the patients. We are very pleased with the $15,200,000 in sales we reported for Exposa during the Q1. This performance is consistent with the uptake indicators we are seeing in the field. Our sales force is experiencing highly engaged meaningful discussions with our target HCPs who are eager to learn about EXFOZA. Nephrology HCPs are rapidly identifying patients who they believe can benefit from therapy, reporting to us that they may have many patients outside of target ranges despite treatment with binders or are intolerant of binder therapy. Speaker 300:09:05HCPs are pleased with the clinical response they are seeing and patients are responding favorably to the treatment experience. Coverage policies are being defined that outline a path to access via prior authorization, attesting to the fact that the patient has been treated with binders and inadequately responding or unable to tolerate the therapy. HCPs are seeing that when prior authorizations are submitted for patients meeting the criteria, patients are gaining access to expoza. Nephrology HCPs and their office staff are responding favorably to our specialty pharmacy distribution network as well as to our comprehensive patient services offering, Ardellix Assist, that further enable patient access through prior authorization support and patient engagement with the affordability programs available to them. Our own internal metrics are supported by external research conducted by Spirex, who is tracking the launch of XPOSA. Speaker 300:10:03According to the April 2024 LaunchDynamics report, nearly all of the 77 surveyed nephrologists, 98% rate exposa as an advance over currently available hyperphosphatemia therapies. In addition, 56% of the surveyed nephrologists reported using exposa and of those, again, 98% report satisfaction with treatment. The research demonstrates that awareness is high among the nephrology community, interest and intent to adopt is high and satisfaction with the treatment is high among users. We will continue to build upon our launch momentum, capitalizing on the high nephrology awareness of the number of patients that are in need of a new treatment option despite treatment with binders and their intent to adopt EXFOZA for these patients. Our go to market strategy is working. Speaker 300:10:56We have established a strong presence in nephrology offices across the country and HCPs are responding favorably to the novel blocking mechanism and clinical data profile. They are identifying patients that could benefit from exposa therapy and with coverage policies in place, patients are gaining access and responding favorably to treatment. We are pleased with the performance thus far and are focused on continuing this growth momentum. We have several exciting months ahead as we will have strong commercial and clinical presence across key annual medical conferences for both Ibsrela and EXPOSA, where we will have the opportunity to present more clinical trial data on our products, connect with the prescribing community and deepen our relationship with patients. I look forward to continuing to share updates with you in the future. Speaker 300:11:43With that, I will hand it to Justin. Speaker 400:11:47Thank you, Susan. I'm very pleased to be with you today to discuss the Q1 performance we reported, which included meaningful progress towards our Xrela net sales revenue guidance, a strong launch of XPOSA, careful management of our finances and a strong cash position. Let's start with revenue. As you saw in this afternoon's release, we reported significant year over year growth bringing our total Q1 product related revenue to $45,600,000 compared to $11,400,000 in the Q1 of 2023. Net product sales revenue for IBZRILLA was $28,400,000 during the Q1 of 2024, more than doubling the $11,400,000 in revenue we reported during the same period in 2023 and a 1% quarter over quarter growth compared to the Q4 of last year. Speaker 400:12:41Volume demand grew for RIBZRILLA during the Q1, which was offset by deductions associated with the reset of annual prescription drug plans. Most notably, this was related to our commercial co pay program. The impact of the commercial co pay program is most significant in the Q1 when most commercial healthcare plans reset and patients have higher out of pocket requirements. As patients fill prescriptions throughout the year and begin meeting their deductible requirements, our expenses related to the commercial co pay program decline. Our gross to net deduction for Imperella during the Q1 was in line with our expectations at 33.5% and comparable to the 33.7% we saw in the Q1 of 2023. Speaker 400:13:28We expect this percentage to improve as the year progresses as it did last year. In addition, we saw the anticipated impact of the prior authorization renewal process that occurs at the start of the calendar year for many healthcare plans. The strong demand and expected improvement in gross to net deductions reinforced our confidence in the ongoing performance of Idrela. As such, we continue to expect that full year U. S. Speaker 400:13:55Idrela net product sales revenue will be between $140,000,000 $150,000,000 Exposa had an exceptional first full quarter performance as we are reporting $15,200,000 in net sales revenue driven by the meaningful demand for this product. Our gross to net deduction came in favorably for XPOSA at 23.8%. As we progress into the launch of XPOSA and learn more about the patient mix that drives the associated gross to net deduction, we will share more. In addition, we had $2,500,000 in combined licensing and product supplier revenue. We are very pleased with our top line results during the quarter, which demonstrated the growth momentum Mike and Susan both spoke to. Speaker 400:14:42At the same time, we continue to be thoughtful on how we manage our expenses. Research and development expenses were $10,600,000 compared to $9,100,000 during the Q1 of 2023. Selling, general and administrative expenses were $53,000,000 for the Q1 compared to $26,800,000 for the same period of 2023. The increase was related to watch activities for XFOZA as well as continued investments to grow Ibsrela, which we made throughout last year. Importantly, our costs were comparable to our spending in the Q4 of 2023. Speaker 400:15:19We expect to complete the current expansion of the Ibsrella sales force that Susan previously mentioned by the end of the Q2. Substantial top line growth combined with thoughtful cost management resulted in a net loss of approximately $26,500,000 or $0.11 per share in the Q1 of 2024 compared to a net loss of $26,800,000 or $0.13 per share in the same period of 2023. The net loss for the Q1 of 2024 included $9,300,000 in combined non cash expenses from share based compensation and non cash interest expense related to the sale of future royalties. As of March 31, 2024, we had total cash, cash equivalents and short term investments of $202,600,000 as compared to $184,300,000 at the end of 2023. This includes $49,800,000 in net proceeds that we drew in March from our term loan agreement with SLR Capital. Speaker 400:16:27We are very pleased with our performance during the Q1, driving top line growth across all reported revenue lines, planning for success, investing in our supply chain, managing our operating expenses and strengthening our cash position. We will continue to be thoughtful with how we deploy capital while focusing on maximizing shareholder value. Speaker 200:16:47With that, I'll turn it back to Mike. Thanks, Justin. I hope that what you took away from our performance during the Q1 is that one, we continue to have high expectations for Xrella, including $140,000,000 to $150,000,000 in net sales revenue this year and on the path to at least 10% market share and $1,000,000,000 in annual revenue. 2, EXPOSA's launch progress is exceptional and it is already beginning to disrupt the hyperphosphatemia market where there remains significant unmet needs among patients. And finally, we're in a strong cash position to invest in growth. Speaker 200:17:25We have a lot of important work ahead of us and we have the team in place who is able to deliver. I look forward to sharing our progress with you over the coming quarters. And I will now open the call to questions. Operator? Operator00:17:39Thank The first question comes from Chris Raymond with Piper Sandler. Please go ahead. Speaker 500:18:12Hey, thanks and congrats on the great success here with Exposa. Just maybe one question on that and a follow-up as well. So I know you guys are early in the launch and you've already established sort of a cadence here for guidance after having a number of quarters that you've set with Abbrella. But just the magnitude of the speed is obviously more than anybody expected. Can you provide maybe any sort of color here? Speaker 500:18:42I think everybody sees the script data and if folks were following that, they're even surprised. Those who've been following the script data closely are surprised by the number. Any sort of color in terms of the uptake in what we should be thinking in terms of the implications for the next several quarters, couple of quarters anyway? And then maybe the follow-up is, I know Mike you're not in the business of predicting legislation, but in the absence of sort of any progress in terms of pushing the phosphate binders into the bundle, pushing that off. At what point do you start maybe planning for that as a reality? Speaker 500:19:27Thanks. Speaker 200:19:29Yes. So Chris, thank you for the questions. I guess first of all, I hope by now you can tell that we're not quitters and that we see what we're doing for patients and the uptake that we see with EXPOSA is and has been absolutely worth the fight that we're fighting. I think as you see with what we've done with Intrela, these IVF C patients as well deserve the attention that we're giving them. What you saw with Xarel is we need and we expect to have roughly 4 quarters under our belts before we give guidance. Speaker 200:19:59We don't want to get over our skis. We are excited and thrilled by this performance. The anticipation for the drug out there, the enthusiasm, our ABDs are staying in the field is remarkable. The ability that we have in helping people through the prior authorization process through our dialysis is working extraordinarily well based on so many learnings that we got through with AZERLA. So although I would like to give you a clear answer on both of those, I'm sorry. Speaker 200:20:25I'm sure you understand that I can't. Got it. Thanks. Thank you for trying. Operator00:20:36The next question comes from Yigal with Citi. Please go ahead. Speaker 600:20:41Great. Hi, Mike and Susan and Justin and team. Thank you so much and congrats as well on a very strong launch. Susan, I just had a few questions on the commercial franchise. Regarding AZERLA, can you comment the percent that were new writers versus repeat writers in the quarter? Speaker 600:21:00And then with almost doubling in the territories, how do you expect that to scale in terms of the size of the base of the go and get them to go and ones where you can add and then reduce the binder and then even add EXFOZA and potentially remove the binder altogether. Do you have any anecdotal or early evidence or data to discuss sort of roughly what percent fall into each of those three scenarios? Thank you. Speaker 300:21:36Thanks, Yigal. Thanks for the question. In terms of the new and repeat writing, we have not disclosed the specifics in terms of those percentages. But what I can tell you that's a really important metric to track is just the persistence of new writers being generated weekly, monthly, quarterly. And what we're seeing since launch is that this has been persistent with new writers being generated constantly on a weekly, monthly and quarterly basis. Speaker 300:22:07So seeing that persist really gives us great confidence in the momentum and our guidance for this year. In terms of repeat writing, what's important to note there is that now that we're several quarters into launch, we have the data to show that new writers write again. So we're seeing that repeat writing is also persistent. Where the growth opportunity is, is in continuing to drive that new writer growth, but then also amongst that growing writer base, really growing depth of writing. So these repeat writers could write more often and for more patients. Speaker 300:22:43And what our sales force is executing on is really driving that broader view based on the foundation of positive experience they've had to date of patients that now really need to be considered as candidates for XERLYNXROLA because they do have persistent symptoms, have been tried on other things and now physicians have seen that there is a path to access and that patients are responding well. So they're broadening their view on potential candidates and that's really an important growth opportunity for us as well. In terms of the sales force impact, that's exactly why we believed it was critical to continue to invest in our sales force footprint because our experience to date shows that the space is quite promotion sensitive. So the more we call on doctors, the more they write Idrela. We see that relationship, the more they engage in all of our omnichannel initiatives and in our programs, the more Xarela they write. Speaker 300:23:34So expanding our footprint from 64 to 124 really gives us an opportunity to get those, get into those HCP offices more frequently to continue to drive, that expanded writing and really capitalizing on the fact that they are broadening their view on patients who are candidates for exposome and at the same time can also continue to penetrate our target space and generate new writers. So really being able to execute to achieve both. Speaker 600:24:05Okay, great. And then if you could comment on the exposer question, if you have any data there regarding the way it's bucketing, reducing the binder versus Speaker 300:24:16Yes. Not specifically from a percentage standpoint, Yigal, but what we're hearing persistently is that all nephrologists in general, nephrologists are just commenting on the flexibility. And that's what's really exciting because that means that that patient group that they identify that they believe is inadequately managed on binders or don't tolerate binders, they see exposa because of its complementary MOA blocking mechanism of action as a drug that that patient could benefit from. And they don't have an in going concern around how it gets integrated because they can be flexible on initiating therapy and then perhaps some of them are initiating, tracking and then taking them off, you know, some of the binders. Some of them just cut the binders right away. Speaker 300:25:01Some of the time they just eliminated entirely, as I mentioned in my narrative. So what we hear more is that each doctor is actually using the drug with this level of flexibility and that they see that as a way to really be able to realize the benefits of novel mechanism exposure across their patients that they see are inadequately managed. Speaker 200:25:24And Yigal, it's Mike. Just one additional comment with that is, I think as we spoke of earlier in other calls is you never had multiple mechanisms like you do with so many other diseases to manage what the drugs are trying to address. It's not going to be a static ratio in any given patient. There's going to be an interim intra patient variability depending upon their serum phosphorus. There's now flexibility and tools for these physicians to finally get phosphorus in the target range that they're looking for. Speaker 200:25:52So I think that's going to evolve. And as we understand that better in the coming quarters, we'll certainly share it. Speaker 600:25:59Great. Thank you very much. Operator00:26:04The next question comes from Louise Chen with Cantor. Please go ahead. Speaker 700:26:10Hi, congratulations on all the progress this quarter and thank you for taking my questions here. So first question I wanted to ask you about was Excoza and the $15,200,000 is all demand sales or is any stocking in there? And secondly, just back on this Buddy Carter bill, if it doesn't move through, then is that $1,000,000,000 of peak sales you have for IVYTHRELA at risk or that is regardless of whether or not buddy Carter happens? Thank you. Speaker 200:26:38Yes. I mean there are 2 different product lines in different patient population. So our guidance with INZRILLA is independent of that. But thanks for asking that. As it relates to stocking, let me ask Justin to address that. Speaker 400:26:52Yes. Thank you, Elyse. It has been really a just in time, if you will, approach with EXPOSIT. So through our network, we've seen very low inventory rates since launch in November. So I would say there's absolutely demand of the patients and not at all any stocking, very limited to roughly between 1 2 weeks at max in the channel. Speaker 200:27:39Congrats on the strong early EXFOZA launch. Two quick questions for me. At this point, I was wondering what the breakdown is looking like so far between patients getting access to EXFOZA through Medicare versus non Medicare? And then comparing the how much of EXFOZA's Strongstar are you attributing to differences in market dynamics versus differences in your commercialization strategy? In other words, is your commercialization strategy for EXFOZA markedly different from that of the early Xarel launch or is the main driver more related to differences and things like unmet need, patient exit rate, etcetera? Speaker 200:28:13Yes, Ryan, thank you for the question. The easy answer is, of course, it's our very, very unique and disruptive commercialization approach. No kidding is I think what we do here and Susan can address it in greater detail. It truly is one about having really good drugs that are making a difference for these patients. Having a commercial team that knows how to communicate that from the omnichannel initiatives and remarkable sales team with feet on the ground, talking to physicians about what these drugs can do for their patients, because these drugs work. Speaker 200:28:45Susan? Yes. Speaker 300:28:47So I would say exactly, to Mike's point, our go to market strategy, actually there are really very important parallels between AZERLA and EXPOSA in the novel MOA and the fact that there's limited options and the fact that there's patients in need of novel options. So where I see where what's an important distinction is that for EXPOSA, we went into the market with a very, very ingoing high level of awareness of exposa across the nephrology target base, and high interest and intent to adopt and high level of awareness on the range of the patients that they see that they have challenges in managing serum phosphorus on binder therapy. So I think there was a higher level of market awareness about both the product and the unmet need. Whereas with EBSRELA, while it's a parallel situation where patients have limited options and are inadequately managed and in need of a novel option, in our go to market approach, it's really our promotion and our education on our target base that really got them to begin to identify, wow, yes, patients are inadequately managed. We never had another option. Speaker 300:29:55Now that we have another option, we're increasingly identifying these patients. We're actually engaging in dialogue with these patients and now we're expanding the way we treat and using IBZRLLA for those patients and adequately managed. So there was a little bit more market need education required on the IBZRLLA side. And those would be the only differences. Path to access is the same and the coverage policies as they're being defined have also been favorable on both sides. Speaker 200:30:26Got it. And then on the Medicare versus non Medicare breakdown for the Q1? Yes, Susan? Speaker 300:30:33Yes. Thank you, Mike. Yes, so right now it's actually really interesting being on the market now for a full quarter that we can see from our IQVIA data what the percent mix is for the expoza prescription and, on average between 55% 60% is Medicare and the remainder is non Medicare. Speaker 200:30:57Got it. Thank you very much. Thanks, Ryan. Operator00:31:02The next question comes from Dennis Ding with Jefferies. Please go ahead. Speaker 800:31:09Hey, guys. Congrats on the solid quarter. A few questions for me, if I may. On gross to net for Xposa, this was definitely better than what people expected in the Q1. So how does this evolve through the year? Speaker 800:31:23And we should use the 23% as the new base going forward? And then secondly, I want to take another stab at this question, but on HR 5074, if the bill is to be signed into law in the first half of twenty twenty five, Exposa would need to go into TDAPA. But then if the bill gets signed, XPOSA would need to come back out of TDAPA. Can you perhaps shed some light on that process and some of the logistics surrounding that? Thank you. Speaker 200:31:59Hey, Dennis. Yes, let me just direct address that quickly. Currently, I think as we've said, our intent is to enter Dada, I think the specifics of what you're just describing, that's going to play out over time. But our current intent is to go through the process. And as we hope and the work that we're doing and what Buddy Carter is doing and others on the hill is understanding how important this medicine is for patients. Speaker 200:32:23This is good policy. This is the right thing to do to ensure that patients get access to a drug that's already beginning to make the difference in many, many lives of dialysis patients. So the work continues and the specifics about how things come in and out based upon these next 6 months or more, we'll get that to you as we also learn. And Justin, if you address the gross to net. Speaker 400:32:46Thanks, Mike. Yes, Dennis, in the Q1, Expose's gross to net deduction was 23.8%. It obviously is very early in the launch and also the Q1 of the calendar year. So as Susan articulated, our Medicare and non Medicare split is around 55% to 60% Medicare and the rest non Medicare. We're still warning the patient mix. Speaker 400:33:09This is going to drive the gross to net ratio through the course of the year. So as a reminder, like I said, it's our 1st full quarter. We're currently estimating that maybe it will slightly increase over the next few quarters. But in general, we believe for the rest of this year, it will be in the mid-20s range. And we will obviously comment more closely if we have greater clarity. Speaker 400:33:39Got it. Operator00:33:45The next question comes from a Ruana Ruiz with Leerink Partners. Please go ahead. Speaker 900:33:52Great. Afternoon, everyone. One for EXPOSA. Could you talk a bit about what the early adopter patients look like in terms of their main features and what's really encouraging physicians to find them and identify them as optimal candidates for EXFOZA? Speaker 200:34:10Yes. I'll ask Susan to address it. But the realities are they're not that hard to find. When we know up to patients are out of range, and they've been waiting for something like this. So it isn't that you have to seek and find, it's you should have asked the question, if you have patients above the answer is of course, yes. Speaker 200:34:30And then we move forward. Susan, sorry, I took the Speaker 300:34:34Yes. No, no, you're absolutely right. But I think in terms of I appreciate your question on who are these early patients we're getting. And I think to Mike's point, first of all, important to know that these phosphorus levels are tracked very closely. So nephrologists have like an ongoing understanding of their patient base and where their phosphoruses are. Speaker 300:34:54So what we're seeing in terms of the patients that are being initiated on exposa right away are those that the nephrologists had in mind that they know historically they've really had challenges in keeping them within target ranges. That's who we're getting now. And what's really important as we continue to execute is now that the EXPOSA is available, to really make sure that the nephrologist begins to adapt their behavior and turn to EXPOSA, when possible, looking at their patients that are outside of target ranges. Speaker 900:35:31Got it. Thanks. Operator00:35:36The next question comes from Laura Chico with Wedbush. Please go ahead. Speaker 900:35:41Hey guys, good afternoon. Thanks very much for taking the questions. Just 2 for me. First on AZREA, what needs to happen to hit the high end of the guidance range now for 2024? And then I just wanted to follow-up on EXPOSA, the conversation around the current Medicare Medicaid mix. Speaker 900:36:00Does that is that where you're projecting at a steady state level? You remain kind of a roughly even split between Medicare and non Medicare patients. And I'm just kind of thinking ahead in terms of revenue that might be more exposed to a TDAPA environment versus not. If you could just share any color in terms of where you see that payer mix split ending up over time, that'd be helpful. Thank you. Speaker 200:36:24Yes. I mean, just briefly address the Isabella question is, it's execution. And everything that we have been doing is what we need to continue doing. The expanded footprint certainly is going to be a benefit as we said trained in the field by the end of the quarter. So that's certainly a big part of it too, but it's execution. Speaker 200:36:43The patients are there, they're waiting and when you ask the right questions, the physicians identify them and we help them go through the prior authorization process. Susan, you want to address the exposure question? Speaker 300:36:56Yes, sure. So I think just as anything regarding exposure at this moment, only having 1 full quarter under our belt. It's hard to predict, Laura. I don't want to give you the impression that this is exactly steady state. However, it is not unexpected when you just understanding the patient mix in the dialysis setting and the mix that we've seen even for the IQVIA data for the binder therapies, this is not unexpected. Speaker 300:37:26But we need a few more quarters before we can tell you for certain. One thing that's important is just understanding that the coverage policies have been defined across all the payer segments. So, and I think that's really what's driving the ultimate outcome in terms of the profile. So that is established and will be consistent as we move into this as we proceed through this quarter and going forward since we have nice coverage policies in place across all those segments. Speaker 900:37:56Thanks very much. Speaker 200:37:59Thanks, Lauren. Operator00:38:02The next question comes from Joseph Thomey with TD Cowen. Please go ahead. Speaker 600:38:09Cohen. Congrats on the strong launch. Maybe on EXPOSA, can you give us a little bit of idea of the authorization process from a physician writing a script to actually getting the drug? And then second, Mike, you mentioned the cash balance. Maybe what's your appetite to invest in R and D either internally in the pipeline or maybe go externally and bring something in? Speaker 600:38:40Thanks. Speaker 200:38:41Let me address both the first and last question is, it's early days for us to be sharing what's on the patient assistance program. So we're going to wait until we've got more experience under our belts with that. And as you saw just under a month and a half ago, we hired Mike Kelleher as our Executive Vice President of Corporate Development Strategy. That should be the signal to your question, our willingness to invest in pipeline opportunities, whether it's organic development or opportunities we may find outside. As I think what we are demonstrating is that the approach that we take to commercialization of drugs is clearly unique. Speaker 200:39:20Our ability to attract remarkable performers in the field, I think is evidenced what you see in both ISRELA and EXPOSA performance. So leveraging that and bringing Mike on board certainly is a big part of us going in that direction. Speaker 600:39:38Great. Thanks. Operator00:39:42The next question comes from Ed Arce with H. C. Wainwright. Please go ahead. Speaker 1000:39:49Hi, everyone. This is Thomas Yip asking a couple of questions for Ed. Congrats on the strong early traction with exposure. Perhaps first question, can you discuss how many patients are on exposure therapy to date and among these patients, what's the split between GI, gastro and then PCP subscribers? And then I have a follow-up question as well. Speaker 200:40:14Yes. It's a little bit hard to hear the question, but I think you're asking about the split of patients in GIs versus PCPs. I think as Susan has spoken about our targets, it's high writing GIs and high writing HCPs who act as other GIs in that big practices. I don't know, Susan, if you want to add anything more to that? Speaker 300:40:34Yes, exactly. So we identify our target audience is 9,000 HCPs that account for 50% of the total IBS C indicated market. So even though so many doctors write IBS C scripts, the opportunity of really targeting this concentrated group that accounts for 50% is really what drives this Abbrella opportunity for us. And as Mike mentioned, what we find is that there really isn't a distinction between PCP and a GI. What we have is the high writing GIs and then we have high writing non GIs that actually behave like GIs and just decide to take an interest in treating IBS C and using the IBS C C indicated drugs to manage their patients. Speaker 300:41:20So it's really not a distinction that's relevant in our go to market approach. Speaker 1000:41:29Got it. And also, can you discuss how many patients are on exposure for efficacy data and also the script data, it can be a reasonable indicator of underlying demand of growth? Speaker 200:41:46I think you're asking how many people are on 60 day versus 30 day scripts. I think again it's early days for us to be sharing that kind of information. Operator00:42:03The next question comes from Matt Kaplan with Ladenburg Thalmann. Please go ahead. Speaker 1100:42:10Hey, guys. Thanks for taking the question. And nice out of the gate launch for Eksoza. Congrats there. Just want to dig in a little bit more to Eksoza's performance during the quarter. Speaker 1100:42:23I guess what that could mean for demand in 2024 and beyond. But I guess especially given the high levels of interest you're seeing in the SPHERIC survey. Were these initial doctors kind of adopters that really take on new therapies? And then will it be more difficult to get additional doctors down the line because these are the early on new therapy interest there? Speaker 200:43:00A quick comment and then I'll ask Susan to address in more detail is nephrologists have been trying their entire careers with these patients to get their serum phosphorus levels in check. And they have been woefully unable to with a single mechanism of action of binders irrespective of the type of binders that it is. Patients don't want to take that amount of material, low phospho suits are unpalatable, it's really a difficult life. And when a new mechanism of action like this comes in and as Susan spoke in her opening statement about how this is being utilized along exactly what the votes were in our AdCom is really heartening. And I think physicians see the opportunity to finally have a tool in their toolkit that may help their patients get into the target range that they've been trying to do. Speaker 200:43:46And as Susan said also in our opening comments that we are hearing from patients and from physicians that these effects are sustained. That's heartening and extraordinarily rewarding that we're going to have that kind of impact on patients. It is early days. You always are going to have early doctors, right? That's not an uncommon phenomenon. Speaker 200:44:06But the difference here is there is not one nephrologist out there that has not struggled with nor one patient out there that has not struggled with how to manage their serum phosphorus. Susan, anything to add? Speaker 300:44:18Yes. I would just say the SPIREX data did report a 56% user base and that's data that was generated in April. So and what we're seeing in the field is that nephrologists really want to spend time with our sales team. We're getting in to these offices. They're learning about it and they do have patients in mind, once they are detailed on EXFOZA. Speaker 300:44:40So I think it's more around it's not around an early adopter profile as much as every doctor to Mike's point has been managing this challenge of getting these phosphorus levels within target ranges with the limited options they have and now are very open to incorporating EXPOSA into the treatment regimen to try to do better. So I think that's pretty common across all nephrologists. Where it's going to be important to continue to move the uptake is to expand their thinking where it's not just that patient that they've always had in mind been so challenging. But now that you have a new tool, as you see these phosphors every month, don't wait for multiple reads or try to make everything work for them on diet or other things, the things that they've struggled with. Now they should treat these patients because of the expanded treatment armamentarium they have with exposos. Speaker 300:45:32So that's what's going to be important is just moving beyond that first cohort of patients that they clearly were waiting for something new and now adapting their practice to having blocking mechanism drug like exposa. Speaker 1100:45:48Thanks guys. That's really helpful. Operator00:45:52This concludes our question and answer session. I would like to turn the conference back over to President and CEO, Mike Raab for any closing remarks. Speaker 200:46:02Thank you everyone for joining us this evening, including our investors who've been on this journey with us, the employees who drive our success, our partners who support us and the patients that we serve. With that, we can close the call. Thank you, operator.Read morePowered by
