Gerard, please proceed.

Thank you for joining us today to review our first quarter's financial results and business updates. I'm proud of our continued progress this quarter in terms of both revenue growth and incremental center openings. Both Hepsado and Chemostat have had an impressive first quarter of 2025, generating a combined revenue of $19.8 million. Hepsado sales in the U.S. contributed $18 million, while ChemoSat sales in Europe added $1.8 million. Thanks to the exceptional efforts of our commercial team, we ended the quarter with 17 treating sites and have since opened an additional two centers, bringing our total to 19 active centers in the U.S. In the first quarter, we continued to solidify the company's finances. With positive cash from operations of $2.2 million and an income of $1.1 million, positive adjusted EBITDA of $7.6 million. Additionally, we ended the quarter with no debt and approximately $59 million in cash and investments. With this strong financial footing, we will continue to leverage cash from operations to support Hepsado's research and development initiatives beyond metastatic uveal melanoma patients. Given our belief that Hepsado and the underlying hepatic delivery system platform has the potential to benefit a much broader set of patients, suffering from cancer in the liver. Turning back to center activations, in the first quarter, we activated the University of Kansas Health System, Cleveland Clinic, and Providence St. John's. So far in the second quarter, we activated Northwestern Memorial Hospital and the University of Miami. In addition to the 19 active treating centers, there are currently 10 centers now accepting referrals and pending activations. With our pace of opening between three to five centers per quarter, I am confident that we are well on track to achieve our previously stated goal of 30 active centers by year end. In the first quarter, we averaged approximately two treatments per month per center, and based on the expected pace of new center activations and mix of existing centers, we expect the average monthly treatment per site to be just under two for the remainder of the year. As we increase our footprint across the United States, we are expanding from four to six territories, with each territory having a liver-directed therapy manager, an oncology manager, and a clinical specialist. This transition to six territories is nearly complete, and we are successfully attracting top commercial talent across the United States to support our expansion. We continue to improve access for patients with metastatic uveal melanoma through our newly implemented Hepsado Kit Access 360 platform. This comprehensive program connects patients with authorized Hepsado Kit treatment centers and supports eligible patients in reducing their out-of-pocket costs. Hepsado Kit Access 360 also includes co-pay assistance for those with commercial insurance and also helps patients explore additional financial support available. The European market continues to experience growth, increasing 29% over the prior quarter to $1.8 million. As we have previously stated, given the reimbursement and pricing challenges in Europe, this market will not be a significant contributor to revenue, at least in the short to medium term. However, given Chemosat holds a comprehensive pan-solid tumor device label, and several of our European sites boast over a decade of experience with Chemosat, the region has and will continue to be a critical source of clinical data. Turning to company-sponsored trials, our clinical team is diligently working to establish sites for our liver-dominant metastatic colorectal and metastatic breast cancer trials, which represent a promising new indication for Hepsado. Our Phase II trial in metastatic colorectal patients received FDA clearance in December of 2024. As a reminder, the Phase II trial will evaluate the safety and efficacy of Hepsado in combination with standard of care versus standard of care alone in patients receiving third-line treatment. Standard of care will be trifluridine, tipterazole, and bevacuzumab. Our phase 2 trial of metastatic breast cancer received FDA clearance in April of this year. The phase 2 trial will evaluate the safety and efficacy of Hepzato in combination of standard of care versus standard of care alone in second- or third-line patients with liver-dominant HER2-negative metastatic breast cancer. Standard of care options will be erubuline, vinorelabine, or capcitabine. Each trial will enroll approximately 90 patients across over 20 sites in the United States and Europe. Both trials have a primary endpoint of hepatic progression-free survival. We anticipate both studies starting by the end of 2025 with enrollment for the metastatic colorectal trial to begin at third or early fourth quarter and enrollment for metastatic breast cancer to follow shortly thereafter. For metastatic colorectal, we anticipate the primary endpoint to read out by the end of 2027 or early 2028. with overall survival data expected to follow in 2028. For our metastatic breast cancer trial, we project hepatic progression-free survival data to be read out in late 2028 or early 2029, with overall survival data likely following in 2029. Our market research estimates an annual addressable market of approximately 7,000 patients with liver-dominant metastatic colorectal cancer advancing to third-line treatment in the U.S., alongside a comparable population of approximately 7,000 patients with liver-dominant metastatic breast cancer eligible for second- or third-line therapy. Each of these markets is approximately seven times larger than the metastatic uveal melanoma patient population, which affects approximately 1,000 patients annually in the U.S. These substantial patient populations face the significant unmet needs as neither systemic therapies nor permanent liver-directed therapies adequately address liver metastases. understoring the urgent demand for innovative treatment options. Our strong start to 2025 was marked by consistent revenue growth and the expansion of active treatment centers adopting Hepstado. In the first quarter, we achieved both positive net income and operating cash flow, driven by robust clinical demand and accelerating adoption among oncologists and interventional radiologists. Our ongoing engagement with these specialists underscores the critical role of whole liver treatment in addressing liver-dominant disease. informing our strategy to pursue additional invitations. These efforts position us to potentially transform care for a broader population of metastatic patients, including those with liver, dominant colorectal, and breast cancer. I'll now hand the call over to Sandra, who will provide a detailed overview of our financial performance.

Thank you, Gerard. Revenue from our sales with Hepzada was $18 million, and ChemoSat was $1.8 million for the first quarter of 2025, compared to just $2 million per APSADO and $1.1 million for CHEMOSAT during the same period in 2024. We recognized gross margins at 86% in the first quarter compared to 71% for the same period in the prior year. Research and development expenses for the quarter were $5 million compared to $3.7 million for the same period in the prior year. Spelling general and administrative expenses for the first quarter were $11.3 million compared to $8.8 million for the same period in the prior year. Our first quarter 2025 net income was $1.1 million compared to $11.1 million net loss in the first quarter of the previous year. Non-GAAP positive adjusted EBITDA for the first quarter was $7.6 million compared to an adjusted EBITDA loss of 7.3 million for the same period in 2024. As Gerard mentioned, we ended the quarter with approximately 59 million in cash and investments, positive operating cash flow of 2.2 million compared to a 1 million operating cash burn in the previous quarter. As of today, we have no outstanding debt obligations and no outstanding warrants. The exercise of Series F warrants resulted in $16.2 million of funding in 2025. The warrants were previously issued in May of 2020 as a component of a private placement, had an exercise price of $10 per share, and expired recently on May 5th. Thank you all for participating today. That concludes our prepared remarks, and I'd ask the operator to open the phone lines for Q&A. Thank you. Thank you.

We will now be conducting the question and answer session. If you'd like to ask a question, please press star then 1. on your telephone keypad. A confirmation turn will indicate that Ilan is in the question queue. You may press star and then two if you decide to leave the question queue. For participants making use of speaker equipment, it may be necessary to pick up your handset before pressing the star keys. Our first question comes from Chase Knickerbocker of Craig Hallam Capital Group. Please go ahead.

Good morning. Congrats on the strong results here, continued progress, and thank you for taking the questions. Just first on center ads, Gerard, you had previously said that you expect the majority of ads to be in the second half of the year. I would say that this is kind of stronger progress than we had expected. You've got visibility on a further 10. Can we add another two to three centers in Q2 here? I mean, do you kind of still stand by those comments that the majority of the ads will be in the second half? Just kind of an update there.

I think it'll be a little more even throughout the year than I anticipated. As you know, I've had a less than perfect track record in predicting center activations. For some reason, the hospitals don't always listen to our timing. But You know, it is a solid Q. I know a few of those 10 will all of a sudden will hit a barrier. I don't know what it will be that will slow them down. So I'm balanced looking at them. I think 30 is about the right number to expect by the end of the year. Hope to do better, but I'm not going to bank on that.

But so more even in the first half and so call it potential for two or three more of those centers in Q2 to come on?

Yeah, I think so. And I think, you know, I think it's going to be more along the lines of, you know, roughly four or a quarter. But again, very difficult, you know, we're talking about small ends and complex processes, but yeah.

Got it. And has there been anything that's changed about the process, any learnings that have kind of smoothed it out? And then you've got a little over two treatments per center per month in Q1. You'd said a little under two kind of for the rest of the year. Can you just give us an update on kind of who these, you know, centers are for the last 10? Do you expect them to be pretty, is there some pretty good potential adopters in there? And, you know, any reason why we're going to see that little bit of a decrease sequentially from that Q1 treatments per center per month number?

Yeah, there are some that we would hope would be of really high value. If you look at just script data who treats metastatic uveal melanoma, Miami should be theoretically a big center, Cleveland Clinic, et cetera. But what we found is even these centers with a lot of patients, it takes a while before they kind of start doing a lot. They'll do a few patients, wait and see. And that wait and see can take, you know, when I say wait and see, it doesn't mean they stop, but they're not going to do a lot. And that can be like a six-month lag before they really hit their stride. So that's why I'm keeping the number a little under two for the balance of the year. And it's been pretty consistent since we launched, just under two. Yeah, this first quarter, you're doing some quick math. It was about two, maybe a little over. But I think as we continue to increase the pace of new centers, I think just under two is probably the right number. Now, you would ask, are there any learnings? I think we're getting better at anticipating where there are hiccups and being much more aggressive to get the multiple, multiple stakeholders in the hospital or the center around the table and talk to them beforehand to try to preempt some of the barriers. So on the margin, yeah, I think we've gotten better at it as we've learned, but still there's just a lot of uncontrollable variables that we have to deal with as they come up.

Got it. And just last for me, Sandra, as we think about kind of basically asking kind of cadence of OPEX here, how we expect kind of R&D to ramp as these studies ramp up and, you know, connected with that, how are you thinking about EBITDA kind of through the year as those expenses ramp for the trials?

Yeah, so, you know, total OPEX, yes, we expect it to increase, obviously, over 2024, as you've already seen in Q1. 2025 SG&A will increase probably 60% over 2024, and that includes our non-cash stock compensation. Stock comp is comprised about 35% of that. Now, R&D is expected to increase, you know, Higher rate over 2024, around 150%, again, with Stockholm comprising about 20% of that balance. In terms of EBITDA, yeah, we had EBITDA margins of 30% in Q1. There is no current target to maintain that EBITDA margin. Now, in the near term, in executing site opening and clinical trial initiatives, we should remain EBITDA positive this year.

Thank you.

Our next question comes from Suyampankula Rammakanta of H.C. Wainwright. Apologies, from H.C. Wainwright. Please go ahead.

Thank you. This is R.K. from H.C. Wainwright. Excellent quarter. It's good on all fronts. In general, in terms of patients undergoing procedures, are you seeing any repeat procedures done on patients over the period that it has been commercial so far? And also, in terms of the centers coming on board, So just trying to understand the cadence in the sense, are some of these centers kind of in that competitive situation where they feel they're within a certain geographic jurisdiction that they need to grab patients as soon as they can, and some of them are, you know, in that process, and that's why you're seeing this higher than expected, you know, increase in terms of coming on board.

Sure. In terms of your question about frequency of treatment, in the clinical trial, it averaged 4.1. And as we look backwards, you know, patients who came on board a year ago, six months ago, et cetera, it seems like we're going to be pretty much have exactly what happened in the trial or close to it. So I think, you know, for those modeling, four is a good number, 4.1 is a good number, you know, It might bounce down to 3.9 at some point or up to 4.2 or 3, but it's definitely in that range. And, you know, that is a big driver for overall revenue is how many treatments do these patients get. In terms of pace of opening, this is about what we expected. Maybe it's a center over or so, but it's about what we expected in terms of pace. Our center is feeling, you know, competitive pressure to get this. It's human nature. I'm sure there's a bit of, you know, hey, XYZ Center has it, so I need it as well. I think the biggest driver, the larger driver, though, is there aren't that many patients in this area. Nobody's really, except perhaps Thomas Jefferson, nobody is, you know, no one has a foundation of their practice based on uveal melanoma, except outside of St. Doc's and Thomas Jefferson. So they talk to each other and share information. And it's very collaborative across centers, we've noted, in this particular disease state with docs. And they're just hearing about good results. And I think that's the biggest driver. An IR or an oncologist speaks to another one at a conference, and they say what they're seeing with Hepsado. And I think that's the biggest driver for centers wanting to bring the product on board.

Thanks for that, Gerard. One last question from me on the European front. If I heard it correctly, the revenues were up 26%. But you're saying it's not a major contributor yet. I get that. But at the same time, every quarter we are watching that and it's kind of inching higher and higher. What is working there and do you think you would want to put additional resources or you just want to wait for it to grow organically to a certain point before you start adding more resources? I know you are also looking for other countries to get reimbursement through. Any comments on that front?

Aside from Germany, there is no other reimbursement in Europe. And we hope to get reimbursement in the UK. We've put our submission in. And hopefully we get approval sometime this year and fund next year. The issue we have is twofold. One is when they look at the price of this, they include the cost of the procedure. The second thing is when they come up with pricing, they do look at the trial, and they say this is a single-arm trial. We factor all that in. We don't think we're going to get much more than maybe a seventh of the U.S. price, which is roughly what we're doing now. So, you know, whatever the TAM is in the U.S., you kind of have to divide that. Let's say Europe's roughly equivalent. You have to divide that by seventh. So there's just less to go after at this price point. It's just not feasible to get the price point we have in the U.S. and Europe. I would invest more if there was reimbursement. When we do get reimbursement, we will invest more in certain markets. But right now, I am willing to do IITs and that sort of thing anywhere in Europe because it generates clinical data. I'm managing it roughly on a break-even basis. So we've probably... added three people in the last two years in Europe, which isn't a lot, but, you know, we're incrementally adding people when we think it'll do some good. But, yeah, my focus in the short to medium term is let's get a lot of clinical data out of Europe. At some point, an indication will come along at high enough volume with the right type of data to get better pricing and higher volume and reimbursement. That's probably not going to be with uveal melanoma. Maybe it'll be with colorectal breast or one of the other indications we'll pursue.

Yeah. So if I can, if I may, one, really one last question on the R&D front, because you just talked about additional indications. So you, you know, on the opening remarks, you know, we did talk about the CRC and breast cancer, but at the same time, I know since chemo side has been in Europe for a long time, are you seeing any, any additional indications that the centers are wanting to do, especially with the liver metastasis in it? And if so, you know, is that indication at a point where we can start thinking about or is it just too early?

Yeah, no. Centers in Europe have done breast cancer. They've done quite a bit of ICC. We've had centers say they'd like to do cutaneous melanoma, but these are like N equals 2, 3, 6, not enough to generate real-world data. The most data that's out there on the product is uveal melanoma. And while docs like to, I don't want to call it experiment, try this for some patients, what will really drive it is us either funding an IIT when a doc raises their hand and asks about it and getting that published or a sponsored trial. But, you know, we're trying to get these docs to publish case studies or small series when I have the data. And, you know, hopefully we'll get some more papers out of Europe based on these small and, you know, retrospective analyses. But I don't think from a revenue perspective, I don't think there's anything to bake into a model that's meaningful.

Thank you. Thank you very much, Gerard, and good luck. Thank you.

Our next question comes from Maria Turbolt of BTIG.

Please go ahead.

Hi, good morning. Thanks for taking the questions, Gerard and Sandra, and congrats on a very impressive start to the year. I wanted to ask here very quickly, I heard mention of the patient access program. I want to understand if there's been any hurdles in terms of payments or anything that you're seeing on the patient access front that's led to the creation of this program or if this was always sort of intended and planned as we typically might see with some of these more rare diseases. So any detail on that and any impacts you might see or expect from it on adoption pace would be great.

Now, in terms of, I mean, we put this in place primarily for co-pays. and the rare patient that had no coverage whatsoever. In terms of the hospitals getting reimbursed, aside from the hiccups that were driven by submitting claims incorrectly, we have seen nothing that gives us any pause about either commercial or Medicare coverage. So I think this is the sort of thing that it's helpful for patients that can lower their copay. If they don't have any coverage at all, we can point them towards various charities that do assist the patients with rare diseases. And I think, as you said, Marie, it is kind of standard practice to have this type of service up and running. You know, if we had been a company with, you know, more resources moving into the launch, we probably would have had it in day one. But we had to wait a bit so we could gather the resources necessary to launch it.

Okay. Glad to see it and glad to confirm that billing is going well. And then we're expecting Chopin data, I think, later this year. Any chance we could start to sort of understand what the bar for what will be impressive to clinicians is? I don't know if you can start to help us set up some expectations for that data at this point, Gerard.

Yeah. The end point is PFS. So I think, you know, a meaningful increase in PFS would, you know, is what we're looking for. What might that be? I think it's in the eye of the beholder. I think anything, you know, any increase of, you know, given how severe this disease is for patients, I think, for example, a four-month increase would be phenomenal, you know, because that probably translates into four months or more life. So... Something in that range, I think, would be great. But, you know, we'll have to see. But that's my kind of personal bar, about four months increase in success would be great.

Okay, great.

Congrats again on the nice quarter.

Thank you.

The next question comes from Sudan Loganathan of Stevens Inc.

Please go ahead. Hi, Gerard and Sandra. Congrats on the great quarter, and thank you for taking my questions. My first one is going to be kind of on the territories that you mentioned. Does the six territories you mentioned cover the lower 48 states and get you to that eventual peak site activation to potentially 40 sites like you've mentioned before? Does your current boots on the ground get you to the over 30 sites, or will there need to be some kind of increase to that SG&A effort to support site activation growth? over 30 sites.

I think we can get to 40 with the six territories. With that said, if it looks like the number of boots on the ground, as some say, is limiting the growth, we'll do more. Luckily, this is not a huge expense. If we went from six territories to eight, that would be an incremental six people. So it doesn't move the needle very much one way or another. So time will tell. Right now on paper, our models say, hey, we should be able to get by with these six territories.

Okay, great. And then my second one, you know, with the FDA's clearance now in hand for the phase two trials for, you know, HER2 negative breast cancer and DRC, you know, what are the remaining tasks prior to initiating the first patient on trial? You know, what's kind of the bars now from initiating a patient, you know, maybe this quarter itself versus, you know, waiting into the third or fourth quarter of this year?

Sure. I've got Boyo virtually here with me. So, our CMO, I'm going to ask Boyo to chime in there. Sure. Happy to address the question.

So, once the FDA clears the protocol, here in the U.S., we engage with clinical trial sites, major centers, to review and approve the protocol, train the site if necessary, and also do the contracting to make sure that the cost of the trial and procedures is covered. So because we typically go to large academic centers which are quite complex to navigate, this process can take anywhere between six and 12 months for the typical treatment centers. So that's why there's a gap between the FDA clearing the protocol and us actually enrolling patients. In Europe, it's a similar situation. We file typically in Europe protocols for regulatory clearance after the FDA has left them, and that's what we've done for these two trials. And in parallel, we engage in sites and repeat the same process. Activation of sites in Europe can also take anywhere between 3 and 12 months, depending on what type of site and which country it is. So there's always an operational lag between clearance of the protocol and start official enrollment. I hope that suggests your question.

Yeah, thank you for the clarity there, Victor. I really appreciate it. And one more last one if I can squeeze one in. I think I believe you may have noted before that achieving that around $13 million in revenues should kind of yield like a break-even EPS. And then over that could yield a positive EPS, you know, with current OpEx levels, you know, which you now have proven in the first quarter. So, you know, congrats on that great milestone. Now that is proven about your business and with the cash decisions you currently have, is there any interest in employing that cash to in-license a companion diagnostic device or therapeutic that could go hand-in-hand with EpsadoKit and be accretive to the business maybe in a shorter timeframe? then running, you know, clinical trials for label expansion and going that route. Just curious, you know, what your level of consideration is for that kind of a strategy.

We always keep an open mind. And, you know, a number of things have come across our desks to look at, none of which seem like it makes sense. I think usually in licensing, it's usually along the lines of what else could the sales force sell in this type of business? I think taking our eye off this very profitable product to sell something that is high volume, low margin, that takes a lot more sites to sell into doesn't make a lot of sense. Now, if something comes along that is more a profile in terms of focused sales focused, highly technical sale, that might make some sense. But nothing's come across to date. In terms of a companion, you know, diagnostic or something, you know, if we do move into an adjuvant setting, which is probably, you know, something we do talk about, but it's not actionable yet. You know, if there was something that, for example, predicted one will get liver mets, we might be interested in funding something like that. There's no such thing out there right now that's just a pickup that's commercialized. That would be more of an R&D investment. But, you know, we look at complementary things like that. If there might be a synergistic systemic, something that for some reason fits with our liver targeted, we would look at that if there's a good clinical and medical rationale. But I don't think there's a lot out there in the near term that, you know, that fits well within the business. We're certainly not going to in-license something just to have a larger top line. Got you. Thanks, Gerard. I really appreciate all the color there.

Again, congrats on the great start to the year.

Our next question comes from Bill Morgan of Clear Street.

Please go ahead.

Hi. Thanks for taking the question. Congrats on the quarter. So looking at revenue in Q1, I just kind of want to look at it from any angle to see kind of how stable this base is going forward with it being such a strong number. So was there any month-to-month variability that might suggest any quarter-to-quarter variability going forward? And were there any headwinds from beginning of the year insurance resets? Thanks.

In terms of the latter part, we expected to perhaps see something with the copase resetting, and we didn't. We didn't expect. We wondered. That's probably a better way to put it. But with a disease such as this, it seems relatively, I won't say immune to it, but it is less of an effect. In terms of month-to-month variability, We're still talking about relatively small ends. So by definition, you're going to have some level of variability. It's tough to tease out a pattern. Since patients are treated every six to eight weeks and probably closer to eight, you know, we do kind of see an up and down effect month to month depending on, you know, if January has a lot and February has a lot. a bit fewer than March is likely to have a lot, and April a bit fewer just due to the returning patterns. But it's not that meaningful. And again, the ends are relatively small, so there's noise in there as well.

Thank you.

Ladies and gentlemen, just a reminder, if you'd like to ask a question, you're welcome to press star and then 1. Our next question comes from Hale Jen of Le Blanc and Company. Please go ahead.

Good morning, Gerard, and congrats on a great quarter. I have a few short questions here. First, in terms of the CRC trials, how many sites you are anticipating to activate for the study?

Avoyo? Sure. We anticipate more than 20 sites across the U.S. and Europe to participate in the colorectal trial.

Okay, great. And the second one is that I don't remember whether you have mentioned how many hapsado units have been sold in the quarter. I guess we can calculate that, but would you be able to just provide a number as well?

um it's not we had a price increase um mid first quarter uh so it probably isn't quite as clear as that um but i think if you just you know divide by about let's say 185 000 you'll get the number or close to it within you know two units or so okay so uh could you elaborate uh the level of price increase uh sandra you Is there a price increase to the timing?

Yes. We started the year on January 1st with a price of 182.5, and on February 1st, we went up to 187.5.

Okay, great. That's very helpful, and thanks. The next question is that in terms of, have you guys thought to track to see how many patients, the breakdown of patients that are actually referred, initially referred by oncologists versus those patients already in the interventional oncology, so to track in terms of the performance of the cell team toward the oncologist.

So are you asking out of the next edition? How many of those patients were already at that center versus were referred into that center? Yes, yes. Kevin, can you give an estimate on that?

Yeah, that's a great question and something we attempt to track as some of our key indicators for the health of the centers that we're in. And I would say that right now, it's probably around 30 to 40% of the patients are organic to the sites that we have opened with the remainder being referred from the outside.

Okay, great. Go ahead.

Yeah, I'm going to say there's two contravening forces there. We try to get better at generating referrals into the centers. On the flip side, as more centers open, there's less need for referrals. But that's a health thing. The reason we structured these territories with three different types of professionals, the liver therapy manager, the clinical support or specialist who's in there, and then the oncology manager, that third person, their job is to get those referrals to those centers. And so they're clearly doing a decent job. Now, some of these patients are self-referrals, but definitely, you know, we're doing the introductions for many, many of these patients, oncologists to oncologists, to keep feeding the pipeline into these centers.

Okay, great. Maybe the last question here is that I'm just doing a quick scan in terms of the top line of particularly a saddle in the United States. And I just realized that you've got roughly a four million quarter over quarter revenue increase up to this quarter. So it's about almost five quarters when we started. I mean, was there any meaning you can extract from this or simply that just wanted to happen?

I think it's, you know, it's driven by center activations. And it hasn't been the same number of centers every quarter, but it's, you know, that's roughly what's causing that increase. You know, we add, let's call it, you know, three to five centers a quarter or three to, that you're going to end up at the pace at which centers do treatments. It kind of leads to that fixed increase every quarter. So it's not an exponential growth like you might get with a drug. But, you know, this is kind of more of a typical device ramp. As you enter more centers, you get the growth.

And actually, let me see the last one here, which you may or may not answer, which is can we extrapolate at least toward the end of this year? I'll pass on that one, yeah. Okay, great. Thanks a lot. And really congrats on the performance.

Thank you.
