With that, I will turn the call over to Glauco's Chairman and CEO, Tom Burks.

Okay, thank you, Chris. Good afternoon, and thank you all for joining us. Today, Glauco's reported record first quarter consolidated net sales of $150.6 million, up 41% on a reported basis and 39% on a constant currency basis versus the year ago quarter. As a result of our first quarter outperformance, we are raising our full year 2026 net sales guidance to $620 to $635 million, compared to $600 to $620 million previously. Our first quarter results reflect strong execution across our global commercial and development priorities, highlighting the commitment of our teams, the strength of our differentiating technology platforms, and our continued progression as an increasingly diversified leader in ophthalmology. Looking ahead, we believe we are well positioned to sustain this momentum driven by two transformational growth drivers, including the continued advancement of the interventional glaucoma treatment paradigm with IDOSTR and the launch of Epiaxa, establishing a new standard in interventional keratoconus and rare diseases. Together, these compelling and durable market opportunities reinforce our confidence in delivering a best-in-class growth profile well into the next decade as we continue to invest in and advance a robust industry leading pipeline while remaining disciplined in capital allocation focusing on roi driven investments to support our near-term objectives of continued operating leverage and cash flow break even now let's discuss our first quarter results in more detail within our u.s glaucoma franchise we delivered record first quarter net sales of 93.5 million on strong year-over-year growth of 58 percent driven by growing contributions from idos tr which generated sales of approximately 54 million in the first quarter idos tr continues to deliver strong clinical outcomes that meaningfully improve patients lives driving strong physician interest and adoption from an execution standpoint we remain focused on our key initiatives including expanding our base of trained surgeons and active accounts, increasing utilization, broadening market access, scaling targeted commercial investments, and expanding body of clinical evidence. On that last point, IDOSTR is supported by a robust and growing body of clinical evidence demonstrating soft strong efficacy, safety, and durability of effect. This now includes 22 peer-reviewed publications, complemented by a broad portfolio of active Phase IV studies across diverse real-world clinical settings, further reinforcing its consistent performance in real-world practice. Importantly, INOS-TR is serving as the foundation for a broader shift towards earlier interventional glaucoma care. Our efforts to educate surgeons and key opinion leaders globally are gaining traction and helping to drive a steady evolution in the standard of care. This momentum was evident at recent major industry meetings, including AGS and ASCRS, where engagement and enthusiasm around interventional glaucoma and our novel therapies were notably strong and growing. To support these efforts, we continue to invest in our commercial organization and infrastructure to expand disease awareness and education, while enabling our customers to effectively adopt and operationalize interventional care into their clinical practice. Moving on, our international glaucoma franchise delivered record net sales of $35.8 million on year-over-year growth of 23% on a reported basis and 16% on a constant currency basis. This strong growth was once again broad-based as we continue to scale our international infrastructure and execute our plans to drive and explore as a standard of care in each region and major market in the world. As previously discussed, we continue to expect new competitive product trialing headwinds in some of our major international markets as we progress through 2026, partially offset by growing contributions from ISN Infinite following its EU MDR certification and associated European commercial launch late last year. We also expect the currency tailwinds to abate going forward based on the current rate environment. And finally, our Cornell Health franchise-delivered net sales of $21.3 million on year-over-year growth of 15 percent, including Fortrexam and very early Epioxa net sales of $17.7 million. At the end of the first quarter, we are delighted to announce commercial availability of Epioxa, our novel groundbreaking advancement in corneal cross-linking for the treatment of keratoconus, a rare site-threatening disease that is currently far too often under under diagnosed undiagnosed and untreated we believe epioxa represents a transformative innovation in keratoconus care offering an incision free alternative to traditional corneal cross-linking procedures as it does not require the removal of the corneal epithelium the outermost layer of the front of the eye this novel oxygen enriched topical therapeutic, bioactivated by UV light, is designed to reduce the pain associated with removal of the epithelium, streamline the procedure, and minimize recovery, all while delivering clinically meaningful outcomes and exceptional value to patients, providers, and the healthcare system. The response we've received from surgeons in the broader ophthalmic community since FDA approval and the more recent initial commercial launch activities has been very encouraging as we've discussed with the launch of Epioxa we have redefined our go-to-market approach to better address this site-threatening disease and truly expand patient care and access importantly with this launch we are substantially increasing our investments in patient awareness education and access while addressing the long-standing challenges of underdiagnosed and under treatment that have affected this rare disease community. As with all pharmaceutical launches, initial patient access will be gated by typical pair adoption headwinds and hurdles, but we've been encouraged by the progress we've made in short order through the early days of our launch. First, I'm proud to report that we have successfully established and continue to selectively expand a broad reaching site of care network. Our acquired O2N systems are already actively deployed across locations serving roughly 65% of the U.S. population, with a pipeline progressing through various approval processes that we expect will expand our treatment center reach to approximately 95%. Looking ahead, we will continue evolving this network to bring treatment access closer to patients as reimbursement and drug acquisition pathways become further established and streamlined. Next, we continue to make considerable progress with payers to secure access pathways or policy coverage for Epioxide, with several plans having already updated or are in the process of updating their policies to include this novel therapy. These efforts are translating into expanded access with pathways now established for more than 100 million covered commercial lives in the United States, including with four of the five largest payers, reflecting encouraging initial receptivity of EpiAccess clinical value. While we expect the pace of policy adoption to build over time, we remain focused on driving broader commercial or sorry broader coverage across both commercial payers and Medicaid programs to support more streamlined access pathways over time. Earlier this month we achieved another important market access milestone as CMS assigned a product specific J code for Apioxa consistent with our expectations and in response for our application the new code j2789 is scheduled to take effect on july 1st 2026 and we believe it will help streamline the reporting and reimbursement process for epioxa among us payers over time until then we anticipate epioxa will be commercially available under a new technology miscellaneous j code and anticipate measured adoption over this initial period until the permanent J code is in place and solidified operationally by providers and our specialty pharmacy. Beyond Market Access, we're proud to lead the way once again and forge a new path for interventional care to conus by advancing targeted marketing and DTC initiatives to drive awareness, education and early detection supported by greater optometric engagement and strengthened and advocacy partnerships. Finally, we launched a co-pay assistance program for eligible patients and are operationalizing a specialty pharmacy in support of Epioxa patients. As you can see, we are very excited by the significant potential Epioxa offers to patients living with keratoconus. While Epioxa remains in the early stages of its launch, our teams are energized and executing with focus, and we're encouraged by the solid progress we're making against our core launch priorities. Beyond Epioxin, we continue to advance a broad and differentiated clinical pipeline across our five novel therapeutic platforms, encompassing 13 publicly disclosed programs and additional undisclosed assets supported by a robust portfolio of active clinical and Phase IV studies. This includes ongoing pivotal trials for iDose T-Rex, iStent Infinite in Mild-to-Modern Patients, and the Presser Flow Microshump, an active phase 2 trial for iLucian Demodex Bluthritis, ongoing development for our iLeak platform, including a planned and market introduction of our KC screening device later this year, and our promising earlier stage retinal assets. Overall, we remain on track with our clinical timelines and encouraged by the progress across our complete portfolio. In conclusion, at Glaucos, we're in the business of pioneering new marketplaces within ophthalmology for the benefits of patients. Our record first quarter performance highlights the strength of our strategy and execution as we continue evolving into an increasingly diversified ophthalmic leader with multiple transformational growth drivers in IADOS-TR and Epioxa and advance our mission to transform vision therapies for the benefits of patients worldwide. So with that, I'll open the call for questions. Operator?

The reminder to ask a question, press star 1 on your telephone keypad.

And our first question comes from the line of tom steven with staple please go ahead great hey guys thanks for the questions nice nice quarter um first one on epiox uh tom or joe maybe if you can talk about early findings one on sort of how initial experiences in sort of the claims and prior off processes are going um And two, what demand in the market looks like sort of from an early utilization standpoint, you know, maybe based on what you're seeing in the Epioxa patient portal. And then I'll have a quick follow-up.

Sure. Thanks, Tom. It's Joe. I'll start off there. You know, I think Tom gave you some of the higher level stats, the progress we're making with the Epioxa launch, both in terms of the two fundamental, you know, I think foundational items, both our site and care network as well as the broader payer pathways underlying that which i think you're asking a good question is the process of making your way through that and clearly it's hard to judge too much on that until we get into the post j code period because at this point you're dealing with a miscellaneous code so all systems around that if you will are by definition slower than normal as you adjudicate on a claim by claim basis but i will say that you know we've been very encouraged by those sites of care who come online as Tom referenced and the patient flow that's coming from that and into our portal of the hub as you say as a leading indicator of what it can mean for the clinical demand associated with with an epi on therapy like epioxide so as we make our way through that and we see those claims get adjudicated which we've seen positive claims get through the process and also those procedures get done now, we're encouraged by I'll call the leading indicator in terms of that funnel as it develops.

Got it. That's great. And then follow up just on Eidos, really solid in the quarter. Joe, maybe to stick with you, can you just talk about drivers of the strength? And it'd be great if you could maybe also discuss kind of Noridian and Novitas versus the remaining max and you know what you're seeing in kind of each of those two pools if you will. Thanks.

Yeah absolutely. I think the most encouraging thing about the results of the first quarter was it was very broad based in terms of what drove that performance. It was continued expansion within the more established I'll call it Max, and you referenced Noridian Novitas, I'll say if I put First Coast in that as well, I'll come back to that. But now you start to see NGS in particular turning on, the early signs of Palmetto turning on as well, as we've more recently achieved a professional fee formally in that region. And I think also encouraging was a real increase, certainly in the funnel into our hub associated with commercial and Medicare Advantage patient flow. So I think it was broad and consistent with what you would hope to expect in the context of our core initiatives. You know, to put a finer point, I think, on your question around Neridian Novotis, typically I talk about that in the context of Neridian plus Novotis and First Coast as some of the earlier um adopting uh max and uh in the first quarter that was down to about 73 percent of the the uh overall you know region volumes if you will um from 78 percent in the fourth quarter and again that's really because as they continue to grow uh you might expect the the adoption curves to be picking up even faster in areas like uh ngs and palmetto boston then congrats again Our next question comes from the line of Adam Mader with Piper Sandler.

Please go ahead.

Hey, good afternoon. Thank you for taking the questions, and congrats on a great start to the year. The first one for me, I wanted to ask a modeling question. So nice Q1, top line B, you raised the full-year outlook by more than the Q1 outperformance. You've given a lot of great modeling color in the past. So, Joe, maybe for you or Alex, can you just kind of pull apart the updated guidance with IDO's contribution versus the spent business versus corneal health, and, you know, as we think about Q2 in particular, and as it relates to Epioxa, would appreciate, you know, if you could give us a little bit of modeling help and then add a follow-up.

Sure, Adam. I'll dive in, and I'll give at least some intricate comments on that front, and if folks have additional questions we can we could add in a little bit deeper but as you said it was a great start to the year um with really each of our franchises exceeding expectations and and we make considerable progress across all those fronts including within interventional glaucoma and idos in particular um and and as a result we were thankful to be able to raise our guidance um you know up to the 626 35 million range and as you think about that in your your models by franchise, a handful of perspectives, first by franchise. On the international glaucoma side, I'd say really that the dynamics here are somewhat unchanged. Obviously, we expect as we move forward here, some of the currency benefits that you heard Tom call out in the prepared remarks will wane. And so we do expect that going forward, we'll see sort of high single-digit growth for the remainder of this year. Now, when you put all that together, that's going to translate into low double digit growth for the full year but the remaining quarters we would expect single digit growth in that franchise on the on the corneal health side um obviously i think everybody knows there's a fair number of moving parts there um it was a strong first quarter but we do continue to anticipate volatility associated with both the potrexid epioxide transition but also the temporary permanent j code transition over the course of call it q2 and q3 and so um when you put all it together with the performance and what we're sort of seeing, we now expect kind of high single-digit growth for this franchise for the entire year with some puts and takes in the individual quarters as we get there. And as you've heard me say in the past, we certainly expect to be exiting the fourth quarter with a pretty strong performance curve as we start to pull through epioxide in a more meaningful way. On the U.S. glaucoma side, again, another strong start to the year, we would adjust our views there probably to be more in the I'll call it a low 30% type growth for the full year. And that's really driven by still an ongoing view that going forward we should expect kind of flattish non-IDOS sales going forward until we've really been proven otherwise and continued sequential progress as we've been seeing with the IDOS launch. So you put all that together and I think as you said, not only did we raise our overall guidance, but we raised it for each of our underlying franchises and the drivers. I will add, just because you asked about, I think for Q2 in particular, given, you know, there's a lot going on here and it's all good, but I want to make sure we've got it as dialed in as possible, that, you know, for the U.S. glaucoma franchise I alluded to earlier in Q2, I think we'd expect sort of a flat non-i-dose and that continual sequential i-dose expansion.

In interventional glaucoma, we'd expect the highest single digits, as we talked about, um you know uh the fx benefit wanes and the cornea side i think as we sent on the last call we would expect in the second quarter to see a bit of a dip there um on a year-over-year basis as we transition um from botrexa to uh tapioxa really appreciate all the color joe and if i could just sneak in the follow-up um wanted to ask idos and we're reaching a point now where you have critical mass from a reimbursement standpoint um so tom or joe can you just maybe talked about some of the the new initiatives that you're going to start to put in place here i think you've talked about growing the commercial team potentially looking at direct to consumer as we

kind of get into the latter part of the year we just love some incremental color for kind of the next chapter thanks again yeah you're you're exactly right adam we've always talked about you didn't want to put some of these things into place until you start to have a more solid foundation from a reimbursement standpoint certainly what you're hearing in the context of our first quarter results and our and our guidance is increasing confidence in that foundation both in terms of the five of the seven you know max that are that have now established professional fees and the teams driving incremental confidence both on the reimbursement side as well as obviously the clinical commercial side but also now increasingly as we move forward here on the broader commercial medicare advantage so you know i think as we've talked about in the past As we move forward here, it's about driving increased awareness for IDOS and interventional glaucoma and teams that help drive that broader environment of both education of patients as well as the process to get them treated by an interventional procedure like IDOS. So we have been making significant investments for some time now in more of our reimbursement and business teams that surround the traditional sales force to really try to make sure that we can maximize both patient access and that broader awareness initiative. So I think you should expect to see more of that, certainly as we get our way into the second half of this year and as we get closer to exiting the year and heading into next. Based upon this trajectory, we're going to feel, I think, a lot more confident starting to make some of those more offensive.

Next question comes from the line of Larry Biggelson with Wills Fargo. Please go ahead.

Good afternoon. Thanks for taking the question. I'll echo my congratulations here. Maybe one on Iodos, one on Epioxa. Yeah. Joe, if you could talk about how you've engaged with the MAC since the CAC meeting last year and any updated thoughts on the likelihood of an LCD this year and the timing of those two RCPs you're running. And I had one follow-up.

Yeah, Larry, I'll start off at the beginning and Tom can comment on the broader studies that we're doing associated with IDOS here in a minute. So, as we think about the engage with the MAC, I'm not sure we have a particularly different strategy here. We've always engaged in an education process to make sure they understand our technologies, how they're utilized, the labels and indications for use around them, and we continue to do that. We continue to try to diagnose where we've got ongoing, you know, I'll call it less streamlined reimbursement in areas like CGS and WPS, and we've continued to have momentum in some of those conversations. So hopefully we're marching forward those two MACs in a productive way that can drive professional fee establishment similar to the other five larger MACs that have come before them. You know, as it relates to the, you know, post-CAC conversation, LCD conversation, really no changes on this front since our last call, Larry, and we've talked about it. But at this point, we've not seen any signs of an LCD, and we continue to believe it would be premature at this stage of the clinical adoption curve. And having said that, obviously, by nature, these things could be unpredictable and opaque. So it certainly remains possible, even if we believe it's less possible.

And I think to address your question on Phase 4 studies, Larry, that we've contemplated actually been enrolling for some time once we received NDA approval, we have done two major Phase 4 studies. The first would be IDOS plus cataract versus cataract surgery alone to be able to demonstrate the incremental value of using IDOS in combination with cataract surgery. And that study is actually fully enrolled, and we'll be following those patients over the course of this coming year, and we'll be looking to publish the data at regular intervals. And I think that will be a very powerful supplement to the data that we currently have on hand. And again, another 22 peer-reviewed clinical trials. And I think we were largely prescient in also doing a study looking at IDOS versus IDOS plus infinite, because I want to show the incremental value of these two different mechanisms of action to be able to lower intraocular pressure to supremely low target pressures, which will, by all evidence, be able to force the progression of glaucoma or progression in glaucoma. I think with both of these in hand, I think it will be timely in case in any event in the future we're challenged by any MACs and using either combination modalities of procedural pharmaceuticals plus MIGs or using IDOS in combination with cataract surgery.

One other thing I'll just add, Larry, I think even at a minimum on this, these studies that Tom's are referencing is important in the broader payer community. So, this is how you continue to expand that coverage, irrespective of MACs and LCDs, et cetera, with the individual commercial players and Medicare Advantage plans to make sure that we're optimizing that access for our patients.

Thanks. And for my follow-up on Epioxide, Joe, I'm going to ask you kind of more of a big-picture question. I think from our past conversations, you felt confident that Epioxide could return to peak you know, for TREXA levels of roughly 18 to 19,000, you know, eyes, you know, by the end of the decade. And, you know, if that's paid volume, that would be, you know, well north of a billion dollars in revenue. So I guess my question is, you still, you know, how are you feeling about, you know, achieving that? And, you know, what is the ramp to that look like? Thank you.

Yeah, Larry, I mean, I think I'll stop short of obviously making the longer term predictions formally and just say I think we have been on record saying you know we view this as a as a you know potential billion dollar plus uh franchise and the the pace in which we we get there um you know we'll continue to monitor as we get into the actual true commercialization especially if we get towards the second half of this this year but you know I think part and parcel with that is um you know I don't think we view it just in the context of where we've been with Votrex patient volumes we're making the investments we're making which are enormous moving forward to drive increased awareness and detection and ultimately action and access in the hopes that we can treat you know quite frankly far more than that we believe that there are more than the 18 to 19 000 eyes at any given time that that should be getting diagnosed and treated, and so from our standpoint, a lot of the DTC and the things that you've heard Tom reference will be putting those investments towards hopefully growing this overall market from a volume perspective over that period of time and getting more and more of these patients treated. Thank you.

And I would just add on that, you think about what the possibilities are to build this marketplace over the planning period, and it's really important to be able to recognize what we have beyond this planning period certainly at the tail end of the planning period this would be the second generation customized algorithms that we have in place for the treatment of keratoponcin that can't help but be market expanding if we show demonstrable changes in k-max for these patients and have the possibility of actually increasing their best corrected visual acuity by virtue of customized algorithms that we're going to be able to dispense and use on relations with Terraconis. So I'm very bullish, not only on the near term of all the different mechanisms we're putting in place to build the marketplace, but our possibility of having a second wind moving into the 2030s, which will increase our presence in this rare disease.

Thank you very much. Thanks, Larry.

Your next question comes from the line of Ryan Zimmerman with BTIG. Please go ahead.

On a strong start here. Just kind of dovetailing on some of the questions before, there's been obviously a lot of investor concern about these LCD risks. I know you just addressed it. But Tom, I guess my question is around the existing body of evidence. I'm wondering if you could kind of talk about it in contrast to the phase four study and remind us what percentage, now that we have you know quite a track record with idos what percentage are you seeing today either in combination with cataract or with another mig in terms of the idos usage and and you know if some of the studies already bear out evidence of combinatorial usage of idos with other products or procedures you know do you think that is sufficient or the phase four study is really the you know necessary to kind of you know refute any concerns there i'll let joe start and i might add some color go ahead joe yeah i'll start on the in the context of the trends that we've seen

um certainly i think they remain consistent ryan with the past commentary the the relative percentage of the procedures done today where surgeons are treating you know glaucoma with idos and at the same time um in in conjunction with the cataract procedure it's growing as expected um given you know obviously glaucoma has already changed the standard of care to those patients, but at the same time, our efforts remain focused on that interventional glaucoma opportunity, and we continue to see rapid growth in the number of standalone procedures. So I would say that the majority of patients last year still saw a standalone Ido's procedure, but the mix is certainly shifting towards in combination with cataract or in combination with another mix, as you might expect, because these physicians are trying to obviously do everything they can to slow the progression of a site-threatening disease.

Yeah, and I would just say, based on the question that you had, that most of the phase four studies we do, and as Joe has mentioned, are really for the payers and for moving into commercial payers and Medicare Advantage. I think surgeons, a priori, already have the confidence that putting IDOS in combination with cataract surgeon is going to yield an incremental effect. I think that you will see that in any channel checks you do. Likewise, the use of combination therapy of IDOS plus an ISTEN-Infinite surgeons will have high confidence that they're going to treat incremental effects. So the studies we're doing are less to be able to drive that portion of the market. They're more to validate surgeons' already existing confidence in using these technologies together.

Understood. And then maybe a question for Joe and Alex even, which is just, you know, operating expense guidance and your thoughts on profitability. I mean, it's almost getting to a point where despite your best efforts, you will become profitable in kind of the next year. And I'm wondering kind of how you think about the ramp and sale, or excuse me, the ramp and expenses needed for Epioxa commercialization and kind of, you know, what that does or doesn't do to your timelines, or at least in our model, our timelines, the profitability.

Hey, Ryan, it's Alex. I'll start, and I'll start with profitability. Again, just to reiterate what Tom had mentioned in his opening remarks. You know, our near-term focus in managing the business do so on a cash flow breakeven and driving basically operating leverage within the P&L, which we're pleased to say we saw in the first quarter. We're glad that, you know, that that execution is happening. But as we look ahead, to your point, you know, we certainly can see with the commercial launches of IDOS and Epioxa that we definitely have a fairly clean line of sight towards that pathway of profitability over the next few years. To your point, some of it will depend on the ramp of these commercial launches and the associated revenues that come with it. But as we continue to manage the business towards that cash flow breakeven, you'll see from an operating expense side that we continue to reinvest in the business and reinvest in these commercial launches. And, you know, we've talked about the fact that our operating expenses will grow this year, year over year, and we need to feel that way, you know. And I'll just give you some commentary now that as we did overachieve in the first quarter, you know, Tom and I and Joe have talked about adding additional fuel to the fuselage and these commercial launches. So you should see the operating expenses pick up slightly and modestly from what we talked about at the beginning of the year. But still in the high teens and still showing that operating leverage overall as we progress throughout the year.

You know, I think, Ryan, the overall, you know, when you hear Tom and I talking about the incremental spending from DTC or otherwise, it's important to note that a lot of that is by its very nature discretionary. So as we look forward, you know, you're thinking about making those investments alongside of the significant, you know, growth that we're achieving and hopefully with the hopes of a return on investment that makes that certainly worth the incremental spend associated with it. So we'll be in a process here where we're continuing to evaluate the effectivity of those efforts and what that return looks like before diving in with two feet, if you will, to go full spend on DTC-related efforts. We've always been pretty disciplined in how we've thought about those types of things. Okay.

Appreciate it, guys. Thank you.

Your next question comes from the line of Alan Gong with J.P. Morgan. Please go ahead.

Thanks for the question. I wanted to start off with one actually on the core U.S. glaucoma business. I think IDOS clearly had a really strong quarter, but underlying U.S. glaucoma also did quite a bit better than expected and grew at a healthy clip year over year, albeit also a bit of an easy comp, I believe.

So when I think about your forecast, your reiteration for flat for 2Q in the year, what are you seeing that kind of supports that outlook? is it just conservatism or are there real challenges that you're seeing out on the market yeah alan thanks for the the question i mean you're you're you're right in the context that this was the second straight quarter where we've seen about the restoration of growth in that non eidos remainder or as you said i think core um u.s glaucoma uh franchise so i think we've certainly seen signs of stabilization of the underlying market there um and and i think that our teams are doing a great job in the on the performance side within that more now more stabilized market as we go forward i think we're just not ready yet to make that call that that is i'll call it the new normal that we're operating in it's been an encouraging two quarters but if we look forward here i think it's still safer for us and for investor expectations to be in that sort of more i'll call it flat year of year basis until until we prove it otherwise on a sustained basis there are some things in there um obviously i think we've benefited a little bit in in the quarter from some supply chain disruptions on the on the competition front um it's hard to measure that i don't think it's material but but that should subside as we move forward here so i think we just want to play a couple more innings here of this on that side before we before we re-rate um

our view on the guidance there got it and then i guess follow up moving on to corneal health You know, you talked about how you've reached coverage of, you know, 65% of the U.S. population with, you know, a blind of sight to reaching 95%, I believe the number was. How quickly do you think you can get to that 95%? Is that a target you think you can reach by the end of the year, or is it going to maybe slow down a little bit now that you grabbed some of the low-hanging fruit? Thank you.

Yeah, thanks, Alan. In some ways, it's actually been accelerating. As you might imagine, once you announce commercial availability and the transition plan becomes more real, what we've seen is more of an acceleration than a deceleration on that front. Having said that, you also know that hospital systems and even certain other customers have longer cycles for bringing on new technologies and new drugs to the pharmacy network and the like. And so I think we'll continue to make substantial progress here every month. And certainly hope that we're getting, you know, there or close to that target in terms of realized side of care network by the end of the year.

And your next question comes from the line of David Roman with Goldman Sachs. Please go ahead.

Thank you. Appreciate you're taking the question. Maybe I could just start on Epioxide here. Could you maybe talk to us a little bit about some of the specific market development efforts that you have underway? And maybe you kind of break them into whether that's physician in practice education, patient assistance programs, and then engagement in education with payers.

Yeah, sure, David. It's Joe. On the epiopathy side, you know, I think about it kind of as follows. So I will repeat what Tom's already said and we've commented on. There's a foundational element that's first and foremost when you're kind of going through the stage of a launch. And that is, you know, that you get the site of care network established, affected, trained, and everything ready there. The second layer of that is that you're engaging with the payers in a way to establish access pathways, and then ultimately from there, further streamlining and optimizing those. And then as you go alongside of that, you start to dial up, I'll call it the more, you know, physician-related and even patient-related marketing efforts. But you don't want to do that too soon in that life cycle until really the overall ecosystem is ready. So a lot of where we're at right now is around the last part of what you said, which is making sure that as we're having success with a side of care network and on the patient side, that the machinery in the middle is working as efficiently as possible to make sure that we're working things through the hub and through our specialty pharmacy and providing that visibility to our customers and to our patients. that our co-pay assistance programs are working as they're intended and all the stuff that probably is a little less interesting to investors but is critically important to the ultimate success here as we move forward. And as I mentioned earlier in the call, we're really encouraged by that initial burst, if you will, of patients that are going in there. And now we have to get through that process of trying to get them on therapy, which can be a lengthy one when you're dealing with a miscellaneous J-code. And so navigating that is paramount for us before we get to, obviously, the formal J code in the second half.

Very helpful. Maybe just a follow-up here on IDOS, and I know you talked a little bit about this, but could you just talk to some extent whether there was any contribution here from having the re-implantation approval that came early in the first quarter to what extent that may be giving physicians increased confidence implanting IDOS and how we should think longer term about the interplay between having the re-administration label and IDO's T-Rex?

Yeah. Well, I can confirm that we've now seen numerous successful re-administration procedures as some of those earliest patients are getting out several years. It's not the predominant procedure being done. It's still a small fraction, but we've seen multiple surgeons do re-administration and do so successfully. We've seen payer policy updates occur and a lot of, I'll call it general progress on that front. So I think we're encouraged, and this is sort of in line with what we always expected, that as the benefits of the initial procedure start to wane, that both the patient and the provider are going to want to continue that therapy given the clear benefits to the patient. So we're seeing that start to happen. And I think as we look out over the long run, certainly, you know, re-administration becomes a much more material part of that overall mix. You know, every month and every quarter that we move forward here, it should be more and more relevant to what we're looking at. But out of the gate, we're encouraged by what we're seeing.

Great. Thanks for taking the questions.

Your next question comes from Richard Neurider with Truth Securities. Please go ahead.

Hi, thanks for taking the questions. Congrats on the quarter. Just I'm wondering if you could give us any kind of color on, you know, what's happened to the provider base as this transition to Epioxa is taking place? You know, I'm not looking for you to necessarily give us a specific number of doctors or your installed base per se, but, you know, do you guys envision just a big concentration over the next few quarters in a small number of providers' hands to getting, you know, to getting all of this refined and figured out from a consistency on the payment standpoint? Or is this potentially going to be broader and not as concentrated than maybe what I'm suggesting as we think through this? Just trying to get a sense for, you know, is it really a dramatically fewer number of doctors or is it going to be potentially broader than that?

And I appreciate the question, Richard. I think, well, first, I think that's the definition of how you do concentrate. And I mean, I think, you know, relative to our Eidos, you know, user base, for example, inherently in Keratoconus, even with Potrexa, you had a relatively concentrated group of centers and sites that were doing the procedures. Now, it won't surprise you, and I think you know that with Epioxa, it was our intent, obviously, to make sure that your initial, you know, site of care network is as concentrated as you can reasonably be to try to make sure you're, you know, close enough to the vast majority of the U.S. population. So inherently, our wave one, if you will, efforts have been very targeted around the country in that context. But I'll tell you, in some respects, our wave one efforts have gone maybe a little too well. And that's caused us to have to accelerate some investments to meet the needs of that customer base and their patients that are coming out of that. So there will always be earlier adopters than mid adopters in any launch. And we'll see that here, obviously, as part of the OXA, but I'm not particularly concerned about any, you know, significant concentration issues in any one or two or even 10 customers. I think it's going to be, you know, measured much more in, you know, hundreds of customers ultimately than it is in single digits.

Yep, that's helpful. And then is there any one area where the spend that you're stepping up from a position of offense, clearly, is directed, now that you've had some early learning experiences, in other words, where are the friction most notable, either to a doctor not wanting to do this, not wanting to buy Epioxa and move forward, or is it more on the pull side from the patients and the demanded awareness increase standpoint? Thanks.

Yeah, I would say it's actually maybe a bit more, so if you think about this, whenever, there's always going to be conversations and education, both by Salesforce and the broader teams, to make sure people understand what we're doing, why we're doing it, how we're doing it, as it relates to that, the AXA launch, and certainly in the future, as we've talked about, there'll be a whole lot more of that spin oriented towards, I'll call it more growth, and DTC education related. Right now, in this moment, where a lot that spend is going it shouldn't surprise you it's much more in that initial lift confidence and process associated with uh claims prosecution and adjudication it's it's about making sure that customers understand how it works that they're successfully seeking prior authorizations that we're supporting that process where appropriate compliant and then ultimately getting those patients access to that care so a lot of it's much more in the machinery i'll call it within the market access world than it is necessarily in marketing or even sales from that statement. Got it. Thank you.

Your next question comes from the line of Mason Carrico with Stevens Incorporated. Please go ahead.

Hey, this is Harrison on for Mason. Thanks for taking the questions here. Would you be willing to provide some color on the utilization of the various cohorts of surgeons trained on IDOS?

Is there a portion of the surgeon base today that you would say has matured at this point with more stable utilization or are you still seeing pretty robust utilization growth across these older cohorts of surgeons too yeah um harrison i i'm not sure i would say that we're reaching um stabilization if you will in in one cohort i mean if you think about it even for some of the earliest um adopters uh there's still ongoing enhancements to how they think about interventional glaucoma, the amount of time they're spending on that versus other areas of their practice, let alone, as we talked about, you know, coming into this year to get on this call, the movement from, I'll call it the more traditional fee-for-service patient population into the commercial and Medicare Advantage world. So I think we continue to see growth across both our more mature customer base, as well as certainly with the addition of new surgeons and new practices throughout the country. So, you know, we're still pretty early in that overall evolution curve, if you will, of that.

Got it. Yeah, that's helpful. And then second question here, could you update us on the progress you've made this year from a commercial payer standpoint on IDOS? I think the middle of last year you called out more than 50% of Medicare Advantage and commercial policies had a positive policy in place. Where does that percentage stand today?

Yeah, so I'm not sure it's changed a significant amount this past quarter, but just to put a line in the sand, sitting here today with IDOS, we have about 99% of patients have an access pathway in the commercial and Medicare Advantage arena. To the point you made in your question, about 50% of those patients are in plans where there's a specific policy attached to it, and the remainder where there's silence, and we're certainly seeing successful pull-through on that. I'll also add that in the early days of the real, we're seeing a very, very high success rate in the context of the prior authorizations that are submitted for these patients across that landscape, which is what you'd expect given the statistics I just got done citing around the broader, you know, patient access panel.

Thanks for taking the questions.

Your next question comes from the line of David Saxon with Needham. Please go ahead.

Great. Hey, guys. Thanks for taking my questions, and congrats on the quarter. I wanted to start on the specialty pharmacy channel with Orasimi. So, I mean, I'd imagine the docs doing Epioxa were previously doing buy and bill with Potrexia. So, you know, maybe new to Orasimi. So, what's the feedback been from them in terms of process and, you know, whether there's any friction in that kind of change of workflow?

Yeah, David. So, I think that historically speaking, it was a mix. there were certainly those customers who preferred to buy and build Votrexa and those customers who acquired it through the pharmacy channel in this case on our case Orsini and that continues going forward I think it will surprise you that certainly amongst our non-hospital based customers the vast majority certainly out of the gate are choosing to access the drug via our specialty pharmacy And so that does mean some of them are doing this for the first time with our channel. I think it's a little too early to comment specifically around that dynamic because, again, it's what I said earlier. When you're in the miscellaneous code environment, even with a perfectly streamlined, I'll call it hub and specialty pharmacy process, the process to getting that access for the patient is much more elongated. And we've only had the drug on the market now for a month. So from that standpoint, I think we're still in the early days of adjudicating those claims and getting access to the drug via the SP channel. But more to come on that. And we're certainly encouraged with the work that Orsini has been doing to make sure that they're in network with these various plans. And I think ultimately that's going to accrue to the benefit of our customers who choose that channel.

Great.

Thanks for that. and then um maybe one for alex just on the gross margin um so maybe remind us you know what your expectations are for for the year and then you know as we go through idos and at the oxa looking into next year kind of how we should think about gross margin uh potential thanks so much you bet thanks david i mean we saw 84 margin in the first quarter which was up 120 basis points from last year so we're that was pleased to see that uh you know and the last call we i gave a range for the year of an expectation of 84 to 86 percent and sitting here today we still continue to feel comfortable with that guidance range for the year uh with expected accretion over the course of the

year as as products like epioxa become a greater share of the mix and then to your point looking forward in 2027 we'll comment more further when we get closer but you would expect accretion uh you know as these products continue to ramp great thank you our next question comes from the line of michael the chrome with jeffries please go ahead hey good afternoon and thanks for squeezing me in here so just to follow up on on the epioxa specialty pharmacy question i mean when you think about uh buying bill you know understanding that specialty pharmacy is coming first. Can you talk about, you know, options that you may have or are evaluating to enable or efficiently enable buy-in bill for Epioxide down the road?

Yeah, Michael, I probably won't go, you know, too far into the details around that, but obviously there's always an ongoing education process around from our reimbursement teams and the experts within that, as well as some of our site of care teams and the like, to make sure those customers understand how the buy and build process will work, the key terms and conditions that we have in terms of our payment terms and things like that, to make sure that we can enable that where customers ultimately choose to buy and build the drug. Obviously, when they think about it from a business standpoint, that can be an attractive an option to them when they've got the right building blocks in place to enable viral activity.

Got it. Thanks, Joe. And then just a quick follow-up on iDose Trio. What's the latest and greatest there in terms of timelines and where we stand?

Yeah, I'll be happy to address that, Michael. As we said before, we would complete and we have completed the clinical study for i-dose trio. We'll monitor those patients over the course of this year. We plan to file by the end of this year, and we expect to be in position for targeted approval in the fourth quarter of 2027. So we're hitting on all marks and all cylinders, and as we talked about before, when we did our human factors analysis, we saw a real strong preference for this new design on the order of 90 percent. So we're encouraged by what we think we'll be able to bring to the marketplace and more encouraged by the ability to drive in-office use over time.

Great. Thank you.

You're welcome.

Your next question comes from the line of Joanne Winch with Citi. Please go ahead.

Oh, hi. Can you hear me okay?

We can.

Excellent. You know, let me do some of our due diligence on IDOS. Physicians are still pushing back, or are pushing back, maybe still is the wrong word, on the price tag of it. And honestly, I'm a little confused by that, since you do have the J code and you do have the reimbursement in place. So I'm sort of curious what your initial conversations are like and what the response is to that.

Yeah, I think, I mean, you'll always have customers with varying views, but I'm not so sure that that's really as material of a driver today as it was when we launched. Anytime you launch a pharmaceutical like we have with Idos or Epioxide, there's a period where you have to make sure that your customers understand the why and how, right? But at this point, sure, there will always be some of that. But for the vast majority of the customers, certainly you can see with the results, we continue to add them and drive that forward. We can continue to overcome that challenge where it represents itself.

Thank you.

And your next question comes from the line of Stephen Lichman with William Blair. Please go ahead.

Thank you. Hi, guys. Just a couple of quick ones on Epioxa. First, as it relates to the transition from Potrexa, are you still anticipating it, Potrexa, to fully sunset by the end of 3Q, or has there been any change in that plan?

No change, and consistently communicated to our customers that we would expect in the third quarter to have that transition, you know, taking place. And, you know, ultimately, we will have Potrexa available in limited quantities through a different mechanism where their physician may require an epi-off-based procedure thereafter. But I wouldn't call that out as a real material consideration for certainly the commercial aspects of it for you all. But for those physicians who seek ongoing access to FOTREXA, we do have a pathway, which we're going to make it available to them.

Great. Thanks, Joe. And then obviously we're at the beginning of the runway with Epioxide in the U.S., but just thinking longer term, what is the potential for expansion of your platforms outside of the U.S., whether it's FOTREXA or with Epioxide?

Yeah, I think it has to be much more selective, and it won't surprise you, Stephen, that today's environment where you're navigating a combination of reference-based pricing initiatives as well as other things in terms of payer dynamics and the like, There are certainly some markets internationally that can support the type of therapies that we're talking about with Epioxa and with Eidos, but also we'll have to continue to evaluate that as the landscape shifts that we bring successor generations of products forward and bring as much of this technology over time as we can internationally. But it's not something that at the moment I would be factoring in an immaterial way into your models.

Thanks, Joe.

Our final question comes from the line of Anthony Patron with Mizuho Group. Please go ahead.

Congrats on the quarter. Maybe one on just keratoconus just broadly. You know, when you think about the disease state that it's just, you know, underdiagnosed, you're getting most of these patients that come in with, you know, stage 2 severity. You know, just thinking about the epioxide opportunity. What is the really true TAM from a patient standpoint in terms of this disease state? I know it's, you know, kind of considered an orphan disease, but I think the prevalence probably stretches to somewhere between 80 and 100,000 patients. So what is the true TAM in terms of prevalence in the U.S., and what is the diagnostic pathway to get more patients into the funnel?

I think, Anthony, it's a great question in the context of, you know, exactly the why behind what we're trying to achieve here. So, when you think about keratoconus as a condition and where we've been, the 18,000 to 20,000 eyes that have been getting treated, we believe is likely going to be proven to be a fraction of what really should be getting caught, should be driven to detection and ultimately into therapy over time. You know, I think our best estimates here suggest that there should be between 50 and 100,000 keratoconic eyes a year at a minimum that are getting diagnosed and treated with epioxide and cross-linking. But we're going to have to find that number out ourselves as we move forward with increased initiatives around awareness and detection and ultimately access that therapy. But we do believe that over time that this could be proven to be more of a rarely diagnosed disease than a rare disease. But today, it operates like a rare disease, and we're going to make those investments accordingly.

With no further questions in queue, I will now hand the call back over to Glavco's Corporation for closing remarks.

I want to thank you all for your time and for your attention today, and thank you as well for your continued interest and support of Glaucus. Goodbye.

Thank you again for joining us today. This does conclude today's conference call. You may now
