Eton Pharmaceuticals, Inc.

And welcome to the In Pharmaceuticals first quarter 2025 financial results conference call. At this time, all participants on the listen only mode. Following the formal remarks, we will open the call up for your questions. Please be advised that this call is being recorded at the company's request. At this time, I'd like to turn it over to David Kempe, Chief Business Officer at In Pharmaceuticals. Please proceed.

Thank you, operator. Good afternoon, everyone. And welcome to Eaton's first quarter 2025 conference call. This afternoon, we issued a press release that outlines the topics we plan to discuss on today's call. The release is available on our website, EatonPharma.com. Joining me on our call today, we have Sean Brangelson, our CEO, James Gruber, our CFO, and Ipek Trinkas, our Chief Commercial Officer. In addition to taking live questions on today's call, we will be answering questions that are emailed to us. Investors can send their questions to investorrelations at EatonPharma.com. Before we begin, I would like to remind everyone that remarks made during this call may contain forward-looking statements and involve risks and uncertainties that could cause actual results to differ materially from those contained in these forward-looking statements. Please see the forward-looking statements disclaimer in our earnings release and the risk factors in the company's balance with the SEC. Now, I will turn the call over to our CEO, Sean Brangelson. Thank you, David. Good afternoon, everyone, and thank you for joining us today. If you were aware or with us for our investor day in March, you heard about Eaton's transformational 2024, and I'm proud to say the momentum has continued into 2025. Our existing products are generating strong growth. We recently added two high-value commercial assets to our portfolio with the acquisition and relaunch of Inc. Collects and Dalsum, and we've advanced our pipeline candidates, setting the stage for two potential approvals in the next nine months. We've seen now sequential growth product revenue for 17 straight quarters since the launch of off-handie sprinkle. Though we are very proud of this track record of commercial execution, we are just getting started. With attractive growth prospects for existing products and a strong late-stage pipeline, we expect this streak to continue well into the future, and we're very excited about what lies ahead. I'd like to begin with one of our important products, Inc. Collects. Inc. Collects is a complex biologic product used in treating patients two years of age and older who suffer from severe primary insulin and light-poke factor one deficiency. SPIGFD affects an estimated 200 children in the United States. When we signed the transaction in the fourth quarter, we were very excited about the deal, given the strong strategic fit within pediatric endocrinology, and what we saw is a very attractive growth opportunity. We are now nearly five months into the transaction, and I am pleased to say that it is exceeding our expectations. We just saw a tremendous opportunity to leverage our existing pediatric endocrinology sales force and commercial infrastructure, as well as make new investments into community initiatives to raise awareness of this ultra-rare condition, which unfortunately has seen an increased number of children going undiagnosed in recent years. At its peak, more than a year or a decade ago, Incolix had 185 patients in the United States, but that number has been declining for years, and was at only 67 patients when we completed our acquisition late December. With the significant investments we've made, plus the hard work of our commercial team over the last five months, I am pleased to say that the trend appears to have reversed. We've now reached over 90 active patients and remain confident that we can reach our goal of 100 patients by the end of this year and even higher levels in the years to come. Missed diagnoses have been a long-standing problem with this condition. When physicians are presented with short of stature patients, an IGF-1 deficiency is not necessarily top of mind. And there's a great habit of automatically prescribing growth hormones. SPIGFD patients generally have normal growth hormone levels, so this treatment is ineffective and delays a proper diagnosis, causing SPIGFD patients to miss the Incolix treatment window. We feel that it's important for all short of stature patients to be screened for severe primary IGF-1 deficiency and are using our deep relationships in the pediatric endocrinology community to drive greater awareness of SPIGFD and push for the screening. Eton is also working to expand access for US patients by seeking to harmonize the US and EU labels. The definition of what constitutes severe primary IGF-1 deficiency differs between the regions. While the height criteria is consistent, the IGF level is not. In the United States, a patient's IGF level must be at least three standard deviations below the median. While in the EU, patients must be in the bottom 2.5 percentile for their age and gender, which translates to approximately two standard deviations. We have completed statistical analysis of the patient registry that has tracked hundreds of Incolix patients over the last decade, and we believe it shows that the product is safe and effective in the slightly broader EU label population. We expect to submit a supplemental filing to the FDA in the second half of 2025. By harmonizing the two definitions, we estimate that up to 1,000 US patients could clinically benefit significantly expanding treatment opportunities beyond the current 200 patients. We are proud of the team's hard work to close, integrate, and relaunch Incolix. The growth achieved in such a short period of time is impressive, and it is clear that a long-term growth opportunity remains without the label harmonization. During the quarter, we announced the outlicensing of Incolix's international lengths to study pharmaceuticals for an out-fork payment of $4.3 million. Incolix's international opportunities are relatively small, highly fragmented, and cost more than 30 different countries, and have slim margins. In addition, the outlicensing eliminated the need for Eaton to make a -million-dollar GNA investment to support global infrastructure, maintain foreign regulatory approvals, and facilitate commercial and distribution activities. We believe the transaction will be far more additive to Eaton's profitability than if we had commercialized the product internationally ourselves. The transaction also provided us with a $4.3 million up-fork payment, recouping a meaningful portion of our initial purchase price and providing excess capital that can be reinvested into our attractive pipeline opportunities. And finally, it eliminated the distraction and resource burden that would have come with managing more than 30 territories and instead allows our team members to fully dedicate their time and attention to our three high-value U.S. product launches in 2025. A survey shares a similar philosophy of putting patients first, so we are confident that they will be a good partner for the product and ensure that the international pace of patients have access to this meaningful therapy. Turning now to Alkindi. This has been a strong growth driver for us for 17 straight quarters with no signs of slowing down. In fact, the pace of referrals has actually increased in 2025. As you may remember, beginning in January, we made our existing Salesforce 100% focus on pediatric endocrinology. We believe this has driven increased efficiency, which is apparent not only in the strong launch of Incolex, but also in an increased rate of new Alkindi sprinkled prescriptions. Through April, the number of new patient referrals received this year exceeds the first four months of any other year since launch. Despite the relatively high discontinuation rate, we have still added a significant number of new patients this year and are quickly closing in on our 500 active patients. E10 has been encouraged by Alkindi's strong start to the year and are expecting the rate of new patient ads for adrenal insufficiency franchise to accelerate even further in the second half of 2025 with the anticipated launch of EG400. As we have discussed at length, we continue to see a large portion of the market using unapproved compounded hydrochlorosolone due to the profits for a liquid dosage form. We believe approximately 50% of young children are using a non-FDA liquid hydrochlorosolone today. With an estimated 5,000 adrenal insufficiency patients under nine years of age, we continue to see a very compelling market on the EG400. EG400's producer date is just two weeks away and we are prepared to launch quickly upon potential approval. We've manufactured our launch inventory and our specialty sales force and production on campaigns are ready to go live. We have been engaged in communications with the agency throughout the review being optimistic that they will meet their producer goal date of May 28th. It's a very exciting time, after many years of hard work, our team is very excited to be on the cusp of making this important medication available to the patients in need. Transitioning now to another significant opportunity, the treatment of Wilson's disease, or Wilson disease more correctly, a rare genetic disorder that causes excessive copper accumulation in the body. Patients suffering from this condition do not metabolize copper normally with their bodies absorbing the copper instead. Prevents it from leaking the body and Galzin is an FDA approved treatment for patients with Wilson disease who have been initially treated with a curating agent. It is the only FDA approved zinc therapy for Wilson disease today. As with Incolux, we were drawn to Galzin as an acquisition because we saw significant opportunities for each and to add value, grow the product and improve outcomes for patients. And similar to severe primary IGF-1 deficiency, Wilson disease is a severely under diagnosed condition with a lack of product investment leading to inadequate awareness and education. Wilson disease is estimated to impact approximately 10,000 people in the United States, but we estimate that only 2000 of those patients are diagnosed and actively on a therapy today. Unfortunately, most patients are not diagnosed until they are in their 20s or 30s when symptoms begin to present after years of excessive copper buildup. This domain diagnosis leads to worse outcomes, including neurological damage and liver failure. The increased frequency of genetic testing in recent years has led to earlier diagnoses, a lot of patients are proactively starting zinc therapy before liver or other damage occurs. But an unmet need still remains. Although roughly 2000 patients that have been diagnosed and are on treatment, we estimate approximately 800 used zinc therapy. While the remainder are on chelate agents. However, due to historical challenges with access, affordability and awareness, most patients on zinc therapy appear to be using -the-counter supplements rather than the FDA approved prescription products. The nutritional supplements are a different form of zinc, which have been shown to be less effective than GalZen. We acquired GalZen because we feel that we are the right company to address this dynamic. We relaunched the product in March with robust patient services, including a $0 COVID. For the first time ever, every most of these patients who lost GalZen can access it, regardless of insurance status. We believe Eaton Cares is one of the most generous by-touch patient assistant programs in industry. And one of the many things that sets us apart from other rare disease companies. Our relaunch has received a warm reception from the community, including patient advocates and leading Wilson disease physician. We are currently migrating patients to Eaton's commercial infrastructure and Eaton Cares program. This migration kicked off in March and will be a multi-month process out of the previous pharmacies work through inventory that remained in the channel. We expect the conversion to be largely complete by the end of the quarter or the third quarter at which time GalZen should begin producing meaningful revenue. I'm pleased to be able to solve the access and affordability issues that have impacted GalZen uses for more than a decade. However, we believe that there is more that can be done to criminalize in outcomes of Wilson disease patients. After access and affordability, the two most common complaints among zinc therapy are the burdensome dosing requirements and unpleasant GI status X. We set out to tackle these challenges with the development of ET700, which we disclosed for the first time in March. ET700 is an extended release version of GalZen, which we believe will eliminate the need for three times per day dosing, as well as potentially reduce the GI side effects that are reported by some patients on zinc therapy today. We initiated ET700 development last year prior to the acquisition of GalZen and have now filed a patent on our proprietary formulation. We're now advancing this program at full speed and working with the top Wilson disease thought leaders to prepare a clinical study protocol. We are preparing for the manufacturing registration batches later this year and have a meeting with the FDA in the second quarter to discuss our proposed clinical program. If everything goes as planned, we expect to file an NDA in 2027. We believe this product candidate is a potential to generate more than 100 million in peak growth. Our metabolic portfolio, which includes carbonic acid, methane, antigen, and build-like, continues to provide steady revenue in cash flow. The group of products produced a solid -over-year growth in the first quarter, but one of reduced significance to ETEM going forward due to the rapidly increasing revenue contributions from our high margin pediatric endocrinology products. Turning now to our development pipeline. During the quarter, we were pleased to report that ET600 passed its pivotal bioequivalency study, which allowed us to submit an NDA for the product in late April. ET600 is ETEM's proprietary patent or patented total solution of desmopressin under development for the treatment of central diabetes insipidus. Leading pediatric endocrinologists have long expressed the need for this product. Because it allows for the small, precise, anti-traitable doses required to treat pediatric patients. ET600 is the same pediatric endocrinology prescriber-based as Alkali Sprinkle, ET400, and Incollects. This should provide an important start once commercialization activities begin. We expect our application to be assigned a 10-month review, which will allow for an approval and launch potentially as early as the first quarter of 2026. Pre-launch commercial activities are already underway and we are excited about the prospects for this important product. ETEM is also continuing to advance Amblydia, which we acquired late last year. Amblydia is designed for the treatment of the ultra rare condition of neonatal diabetes mellus, which impacts an estimated 300 children in the United States and is within our pediatric endocrinology call point. Although the product has been approved in the EU since 2018, there are currently no FDA approved oral treatments for the condition and therefore it is not possible for infants in the US to receive the correct dose in an FDA approved manner. Today, caregivers must either obtain a suspension from a compounding pharmacy or crush adult tablets to create a suspension at home. Similar to ET400 and ET600, Amblydia gives us an opportunity to bring a liquid formulation to the market to provide precise and accurate pediatric dosage. Our acquisition terms allow us to have an FDA meeting to receive confirmation of the clinical pathway before any payment occurred. This meeting occurred in April and we were pleased with how it went. The FDA was receptive to what we believe is a feasible clinical pathway to bring this critical treatment to patients in the US. In the first quarter, we also unveiled another new internal development program, ET800. Our French development project will continue to work on advancing the ZENEO hydrocortisone autoinjector and separately ETIN will manage the development of this injectable vial product, which we are calling ET800. In addition to the large and detailed opportunity hydrocortisone injection, which we have discussed extensively, there was an even greater use of the hospital setting. A total of more than five million vials per year and approximately 100 million sales per day. Today, hospitals use a liapalized, reprieve-striped outer vial, which must be manually reconstituted prior to administration. We have developed and filed a patent on it prior to -to-use liquid formulation that we believe will save time, reduce the risk of medical errors, and is an important factor as hydrocortisone is often used in the emergency room and operating rooms. If development activities progress as planned, we expect to make registration batches in the coming months and submit an NDA in early 2027. On the business development front, we expect acquisition and licensing transactions to remain a central part of our one-term story and we continue to evaluate new opportunities. We've demonstrated that we can successfully execute value-creating transactions and we expect to continue to do so. However, our strong position allows us the luxury to remain disciplined and focus solely on products that are aligned with our -rearly-deed strategy and can meet our high threshold for financial returns and value-creation opportunities. As you have heard today, it's a very busy time indeed. We have made great strides in our mission to bring as many new rare disease treatments to patients as possible. With two major product launches, three launches already underway this year and the largest launch in our history, potentially a matter of days away, there's never been a more exciting time for the organization. Following the expected launch of ET400, we see a clear path to reaching 100 million of revenue in the near term and much higher levels as our pipeline products come to market. Through years of hard work, our team has built an extraordinary organization and we continue to make progress every day toward our goal of becoming one of the leading ultra-rear disease companies in the world. With that, I'll turn it over to James, our Chief Financial Officer, to discuss the financials and to discuss the tariff questions. James? Thank you, Sean. I'll start by addressing the tariff situation in the US since that seems to be at the top of everyone's list of questions right now. We believe Eaton would see minimal impact from any of the tariff proposals discussed to date. The majority of our products are produced in the US. Eaton does not hold any IP in any foreign countries and we do not have any inter-company transfer question arrangements. Our primary exposure would be with Incralex and Alkindi, which are both manufactured in Europe. However, the anticipated cost of products purchased from Europe represents less than 5% of our forecasted revenue. So a 20% tariff on European purchases would impact total company gross margin by less than 100 basis points. And the potential impact would likely be even smaller in future years since our late-stage pipeline products, ET400 and ET600, will also be manufactured within the US. In short, we are not concerned about the impact of tariffs, but we will continue to monitor the situation closely. Turning to our financial results, our first quarter revenue was 17.3 million compared to 8.0 million in the first quarter of 2024, an increase of 117%. Net sales during the quarter included 3.3 million of the licensing revenue, of which 1.8 million was from the licensing of Incralex rights outside of the US. Although Eaton is receiving 4.3 million up front, accounting guidance results in recording 1.8 million immediately, with the remaining 2.5 million recognized over the licensing term. We also recorded 1.5 million of licensing revenue from a regulatory milestone event associated with our previous divestiture of DS200. There was no licensing revenue recognized in the prior year quarter. Product sales were 14.0 million for the first quarter of 2025, compared with 8.0 million in the first quarter of 2024, an increase of 76%. This growth was driven primarily by increased sales of Alkindi Sprinkle and the addition of Incralex, which was acquired in late December. We expect product sales to continue growing quarter over quarter throughout the rest of 2025 and beyond. We continue to expect to exit 2025 at an approximately 80 million annual revenue run rate. Gross profit for the quarter was 9.9 million compared with 5.0 million in the prior year period, primarily due to increased product sales. Adjusted gross profit, which excludes the impact of acquired inventory step-up adjustments and intangible amortization, was 12.0 million, or .5% of total revenue, versus 5.2 million of adjusted gross profit, or .6% of total revenue in the prior year period. This increase was driven by continued growth of higher margin Alkindi Sprinkle and the recognition of higher margin licensing revenue in the first quarter of 2025. We expect to report full year 2025 adjusted gross margin of approximately 70% and long-term adjusted gross margin to exceed 75% by 2028. R&D expenses for the quarter were 1.2 million compared with 0.7 million in the prior year period, primarily due to increased expenses associated with our ET700 and ET800 project development activities. It's worth noting that in April, we paid a $2.2 million NDA application fee related to our ET600 submission. That cost will be fully recorded this R&D expense in the second quarter, and we also expect to record a $500,000 expense for an AMLIDIA licensing payment in the second quarter of 2025. Besides these two one-time items, we expect R&D spending to remain largely in line with historical levels for the remainder of 2025. General and administrative expenses for the quarter were 9.2 million compared to 5.2 million in the prior year period. As mentioned in our fourth quarter fall, increased SG&A expenses in 2025 were planned and necessary to build out the infrastructure needed to support the significant growth in our product portfolio and revenue base. These incremental investments include our new dedicated five-person metabolic sales team, which launched on January 2nd, commercial investments made in the product relaunches of Incrolex and Galvin, investment in our ET400 launch readiness activities, and additional corporate staff to support the growing portfolio in the areas of quality, regulatory, and finance. On an adjusted basis, which removes the impact of share-based compensation, transaction-related costs, and other one-time expenses, G&A expense was 7.3 million compared to 4.4 million in the prior year period. In addition to the planned increases in our infrastructure, SG&A expenses during the quarter were also affected by relaunch and prelaunch commercial activities in the period. We are not planning to make further significant investments in SG&A this year and anticipate that adjusted G&A spending will remain flat or slightly decline to the remainder of 2025. We believe that the investments we've made in G&A during the quarter will support revenue levels much higher than where we are today, and as a result, we expect a return to minimal G&A growth in 2026 and beyond. Adjusted EBITDA for the first quarter of 2025 was 3.7 million compared to 0.5 million in the first quarter of 2024. Total company net loss was 1.6 million for the quarter compared to a net loss of 0.8 million in the prior year period. Net loss per basic and diluted share was six cents during the quarter compared to net loss per basic and diluted share of three cents in the prior year period. On a non-GAAP basis, we reported net income of 2.4 million for the first quarter of 2025 compared to 0.2 million in the prior year period and diluted earnings per share of seven cents for the first quarter of 2025 compared to zero cents in the prior year period. Eaton finished the first quarter with 17.4 million cash on hand, and we generated 2.1 million of operating cash flow during the quarter. This concludes our remarks on first quarter results, and with that, we'll turn it over to the operator for Q&A.

Thank you. Ladies and gentlemen, to ask a question, you will need to press star 11 on your telephone and wait for your name to be announced. To withdraw your question, simply press star 11 again. Please stand by while we compile the Q&A roster. Now, first question, coming from the line of Chase Nickerbacher with Crate Hallow-Mulan is now open.

Good afternoon. Congrats on the results here, and thanks for taking the questions. Just first on Incralix, Sean, have you had your meeting with FDA to discuss that label expansion at this point?

The meeting request has gone in, so we'll be looking forward to having that, I would say, in the coming weeks, possibly, most likely July, in my opinion, and then it would follow ideally with the submission in the third quarter of the actual update. We believe the data we have is compelling. It's based on patient registry data out of Europe, and should support that label change.

Great, and maybe staying on the FDA front, appreciate the commentary on ET400. Any additional color on any recent interaction with FDA that you can give us? I mean, are things progressing as you would expect with the review at this late of stage, as in things like manufacturing inspections and final label discussions, et cetera?

Yeah, typically, we're looking at the final label as the last step in the review process of an NDA drug application with the labeling discussions. And so the FDA provides commentary on your label, and what I mean by that is the package insert. We've received that commentary. We have already had the submission sent back to the agency, and so we believe that should be the final step. I mean, we could hear something else, but it seems to me that we are on track for approval here in two

weeks,

or less.

Great, and on the AMGlidia front, sounds like you liked what you heard there. Does that mean you expect to just need a fairly simple kind of PK study to support an NDA filing there, or just kind of any additional color?

Yeah, so we like the feedback of the agency because you can tell during the time, they would like to see us develop and get this product on market. They provided a pathway. It didn't seem like they were fairly clear to us in what we need to do. We did have a few clarifying questions, so we are planning a follow-up meeting with the agency to ensure that we're doing what they want and what their expectations are. But I was very encouraged by that, by the comments that we received back, and I do expect that it would just be a fairly straightforward PK study, as you indicated.

Got it. Pretty impressive continued progress on Incralix. I think you said 90 patients. If I pursue the commentary on Incralix, on Sprinkel, I mean, it doesn't take much for that $80 million run rate in Q4 to start looking pretty de-risked. Is there anything I'm missing there, or maybe any comments that you would have on that Q4 run rate?

No, I think at the appropriate time, we feel very comfortable with the number. First, address your question there. The question is, will we be revising that number at some point? I think we're gonna leave it where it is right now, and we'll see where the sales go in the second quarter. But we're feeling pretty good about our sales, as they've been strong across the board, and we couldn't be happier with the Incralix launch and the quick addition of patients. We think the coming weeks here will help us to maybe provide some update on the next conference call.

I'll leave it there. Thanks, guys. Great,

thanks, Trace.

Thank you. Now, next question coming from the lineup, Madison El-Sadi from B-Riley. Your line is now open.

Hey, you guys, thanks for taking our question, and congrats, really firing on all cylinders here. Yeah, so could you maybe provide an update on the recent weekly Incralix prescription trends? I mean, it really looks like March was a tremendous month. Is that kind of the proxy of the barometer going forward? Yeah,

sure. On that point, I would say that we're significantly increased the number of patients. Now, as we increase, we expect that rate would go down. You're getting closer to that, whatever, 185 potential patients, let's say, that are in the US. So we would expect that, but as it stands today, firing on all cylinders in terms of the launch on that product, we expect to hit our goals, our revenue goals, or exceed them this year. I think we'll exceed those goals. Like to get a few more months under our belt, and then we'll provide an update. And I think we probably, we did indicate that we're down to 90s on the patient front. We'll get further updates on that rate, and better answer your question in terms of the trajectory of it.

Got it, understood. And then on ET400, if we assume approval is on time, what's the expected timing to the first commercial revenue that you would book? Do you think this could be an end of two queue story, or maybe early three queue?

I'm thinking more of a queue three. We will be launching it essentially right around the approval date. So we would expect a June, let's see, first week of June launch on the product. It takes a little bit of time for the patients to get the prescription, because patients have to come back to the office, and the doctors have to prescribe it. So I would say there's a bit of a lag between the initial launch, and then the actual revenue coming in. So from a revenue standpoint, I would really think more about that. Queue three, queue four, it will, we believe, have a rapid uptake. We know that it's something that there's a lot of pent-up demand for an oral solution. So maybe I'll leave it there and give you an idea. It won't have a massive impact in terms of revenue this year, but we think it will have a much more significant impact in the quarters after that.

Got it, Sean, thanks for that. And then lastly, I really appreciate the color on the tariff risk exposure, which looks to be really a non-story. Any commentary to theoretical exposure to the White House executive order, the favor nation policy?

Yeah, thanks for the question. It was probably the same question on others' minds. You know, when I first heard about that, I really didn't know what to make of it. There weren't enough details that were released around that, but now that we've had a chance to look at and digest that, and I've also been able to do a little bit more background research on it, I do not believe it will have a meaningful impact to us. We only sell in the US, so we're not selling products overseas to foreign customers at lower prices than we sell in the US. We believe that alone is pretty strong in the sense that we don't have dual pricing as big pharma does. So my opinion is this is something that would potentially impact big pharma, but we're also less relying on Medicare, Medicaid, than most pharma companies. Really, we have no Medicare business to speak of. It's only Medicaid, and on Medicaid, we lose money on any collections. I think a couple of people have talked about that, but we make money on Medicaid through products like I think it would be Kirk-Lumix. There are no plans for us to sell our products overseas, so that reciprocal or most favored nation pricing would not apply. We believe that for our company, I'm not asking this, because we are a rare disease company, an ultra rare disease company, so I think that it's a unique situation compared to more of your standard pharma circles.

Got it, thanks for that. Makes sense, I think that's a good one.

Cool. Yeah, our pleasure.

Thank you. Our next question, coming from the line of Swayam Pakula Ramakant from HC Wainwright. Yolanis Malpin.

Thank you, this is RK from HC Wainwright. Good afternoon, Sean, Jen, and David. I know you have had more experience with the relaunch of Incorlex compared to Galzin, but in general, what's the feedback from the sales force on Galzin? Anything anecdotal you can tell us about how the relaunch is going and what the expectations are internally for adoption during 2025?

So Galzin is an important product for the company. It's placing us squarely in the Wilson disease space, and we aspire to become a key player in Wilson disease beyond just Galzin. Obviously we have our ET700 product, which is an extended release version of Galzin. That product we think will have clinical trial results in January. That's a small study we're running, which will show the same efficacy, we believe, as the three times a day dosing, hopefully less side effects. So that is really the big opportunity, is the extended release version. The Galzin itself is now, it's been great for patients because they had in the past supply issues, they no longer have that. There's a zero copay, they never had that in the past, they have that today. There's overnight shipping, so we get the product to them very quickly. So we believe that product will add appreciable revenue in the quarters to come. The uptake and the conversion is going well, and we add patients weekly on Galzin. So we see a steady stream of patients coming off of, let's say, over the counter stuff or compounded medicine, and they were forced to go there, frankly, in the past, because of the inaccessibility of the medicine and the high copays that were charged by the part company. We've taken away all those blockades. So I think, and then last thing I wanna say is we're adding a really strong relationship with the Wilson Disease Foundation and with really some of the leading prescribers in the United States that treat Wilson disease. We have been able to get their, hear what their thoughts are, how we can help patients, how we can do the best job to make sure that these patients are served properly.

Thanks for that. Do you, by any chance, are you able to give us patient numbers that are on Galzin at this point, or we have to wait for the next update?

I think for the next update, we'll provide patient numbers because it's still in the transition period, but I can tell you that it is going better than, according to plan, and I'm very pleased with the launch and the job that our Chief Commercial Officer, EPEC, has done with the organization. We have a dedicated sales team in that space, just like we have a dedicated sales team on our other endocrinology products.

No, perfect. A quick question for Jim. Looking through the cash flow statement, I see an increase in the Medicaid rebates and also on the receivables. So is this, just trying to understand what's behind those numbers and how sticky are those?

Sure, let's start with the receivables. So significant increase there. Part of that was called normal operating activity with the addition of Incralex. We talked about significant impact with Medicaid there. So with that product relaunch, decent amount of addition, sorry, with Incralex receivables. With the licensing revenue, even though we only recognized 1.8 million of the Esteve licensing deal revenue in the first quarter, there's a receivable payment of 4.3 million. So we have not received that yet. So a big chunk of the $5.8 million increase receivables was licensing revenue. And then the remainder was just Incralex sales. On the Medicaid side, the increased liability was almost entirely due to Incralex, the product relaunch. So nothing out of the ordinary with the increased liability other than the fact that, and we have a traditional patient mix in Incralex and dollars are just higher with that product.

Okay, thanks for that clarification. Appreciate you taking my questions, folks.

Our pleasure, thanks, Artete.

Thank you. And there are no further questions in the queue at this time. Ladies and gentlemen, this concludes today's conference call. Thank you all for your participation and you may now disconnect.
