Eton Pharmaceuticals, Inc.

Good afternoon and welcome to the Eaton Pharmaceuticals first quarter 2022 financial results conference call. At this time, all participants are in a 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 Krempa, Senior Vice President of Business Development and Investor Relations at Eaton Pharmaceuticals. Please proceed.

Thank you, operator. Good afternoon, everyone, and welcome to Eaton's first quarter 2022 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 Brinjelson, our CEO, James Gruber, our CFO, and Kevin Guthrie, our Executive Vice President of Commercial. 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 etonpharma.com. Before we begin, I would like to remind everyone that statements 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 filings with the SEC. I will turn the call over to our CEO, Sean Brinjelson.

David, thank you. Good afternoon, everyone, and thank you for joining us. On today's call, I will discuss our strong first quarter commercial performance as well as some product-related development updates. Starting with the commercial results, very pleased with our revenue that we posted in the first quarter. It was our fifth straight quarter of sequential growth in product sales and royalty revenue. And we expect that streak of sequential growth to continue throughout the rest of this year and into the foreseeable future. In the first quarter, we reported product sales revenue of $2.2 million, which was double what we had reported in the fourth quarter of 2021. Our revenue continues to build month over month. Alkindi, cargumic acid, biorphine all saw record revenue levels in April and are also expected to exceed those levels in May. These products are starting to gain significant traction and yet are still in the early stages of their launches. So I hope it's becoming more evident to investors that they hold significant revenue potential for the company. I believe it will be even more apparent as we report the coming quarters throughout the rest of this year. I continue to expect us to report more than $25 million in revenue this year, composed of $10 million of milestone payments and at least $15 million of product sales and royalty revenue. By the way, on a side note, I wouldn't say we're going to hit $25 million. If I didn't think we could at least hit that, I think we could probably hit more. To be clear, the $15 million of product sales is only from products on the market today, and any of our potential new approvals and launches in the back half of the year would be additional upside. Turning to product-specific updates, I will start with curglimic acid, which we launched in late December. We are very happy with the performance of curglimic acid, and it is tracking ahead of our original expectations. I'm also pleased to report that we had numerous patients initiate treatment during the quarter, and more have initiated since quarter end. Product earned a meaningful revenue in the first quarter. Many patients joined mid-quarter to start on what we call a quick start, so the full revenue contribution from the product will be more pronounced in the second quarter and also in the rest of the year. The product's reception from patients and physicians continues to be overwhelmingly positive. They are excited to have another treatment option and are particularly pleased about our product's room temperature storage compared with the refrigeration requirement associated with the competing product. Our team exhibited at three of the most important conferences in the field over the last eight weeks, which provided us with valuable interactions that we believe are likely to translate into additional patient conversions in the coming months. We continue to make strong progress towards our goal of taking 25 to 35 percent market share of this more than $50 million market before the end of the year. Turning to Alkindi Sprinkle, Alkindi Sprinkle also had a very strong quarter, first quarter. We added more patients on treatment in the first quarter than we had in any quarter since launch. Alkindi sales continue to grow month over month, with April well exceeding March levels and May expected to grow from April. While the product posted solid growth in April, the number of new patient ads was not as high as the record number we saw in March. We believe the slower growth rate in April could be due to some organizational changes implemented by our co-promotion partner, Tolmar. However, there's large sales force, which was previously selling into two call points, both pediatric endocrinology and oncology, is now in the process of shifting that into two separate sales forces. So there will be a new sales force, 100% dedicated to just pediatric endocrinology. And we also believe this change is a positive, may cause some short-term disruption, but ultimately will be a long-term benefit as these dedicated sales reps will build deeper relationships and more frequent interactions with the prescribing doctors. Our partner expects to have these changes fully implemented by July, and so the disruption will be short-lived. We also saw good results from our hospital products in the quarter. Biorphin ampules continue to see increased adoption and record sales month over month. While the current sales are not yet reaching their full potential due to the ampule container, I am pleased to share that we finally have submitted our prior approval supplement for the vial format and have been assigned a target action date of August. Based on the feedback from customers, the conversion rates of these ready-to-use products are going to be significant. We continue to believe that the long-term opportunity for the Bryorcan franchise is in the millions of units annually and tens of millions of dollars annually. Our partner, XGen, also launched ResiPress ampules in the first quarter. We expect to submit the prior approval supplement for the ResiPRESS vials later this month, which would allow it to be approved before the end of the year. Unfortunately, since the launch of the ResiPRESS product, we have seen increased competition from other ready-to-use ephedrons in the market. However, given that market is estimated to be more than 10 million doses annually, we still believe there's ample opportunity for this product to provide a meaningful profit contribution. On the R&D side, we have had a very productive couple of months since our last call. Most notably, we received final FDA approval of our cysteine injection product, bringing us up to a new total of seven FDA-approved products in our portfolio. The team continues to execute. We were the first to file an ANDA on cysteine injection. We've also been awarded 180 days of generic exclusivity if we successfully overturn the patent. The trial took place in March, and we expect to receive a judge's opinion by August. We are taking steps to prepare for launch so that we can be ready to commercialize the product shortly after the judge's opinion is positive. We estimate the current Cysteine market well in excess of 50 million annually. As you may remember, our partner has been manufacturing Cysteine in its current formulation for more than a decade, well before Accela began working on its product or filing its patent So we believe we have a very strong position in this case. In addition, we believe the fact that our product has now received final approval by the FDA further strengthens our case. We also announced today our development project for a biorphine premixed bag, which I am very excited about. We believe this would be a critical product and address a significant unmet need in the marketplace. Currently, hospitals must manually mix up their own bags or purchase premixed bags that are not FDA approved, have not been shown to be safe or efficacious from compounding pharmacies. We expect to submit the NDA for the product by the third quarter of this year, which could allow for approval as early as the first half of next year. And this is one of the most in-demand, premixed products that we've encountered. In recent weeks, we also received good news on our zonisamide suspension product. Our partner received notice from the FDA that the manufacturing site inspection has been officially resolved and the facility was deemed ready for commercial manufacturing. As you may recall, the only previous deficiency in the application was the lack of the manufacturing site inspection, which had been delayed by COVID. Now that the inspection is behind us, we expect to see the application approved on or before the newly assigned target action date of July 18th. Eaton would receive a $5 million milestone payment from Missouri upon the launch of this product. We are also waiting on the upcoming PDUFA date of May 30th for our Lamotrigine product candidate. Our partners submitted the product's human factor study data in the fourth quarter of 2021, which we believe addressed all of the FDA's requests and allows for the product approval later this month. We have no reason to believe that the product would not be approved by the end of this month. The launch of the Lamotrigine product would also trigger a $5 million payment to Eaton. While I've been excited about Eaton's prospects, I hope it's clear to investors that we are positioned for a great 2022. With our commercial products ramping up quickly, we are poised to deliver significant revenue growth to shareholders throughout the rest of the year. But on top of the existing products, we have potential launches in lamotrigine, zonisamide, biorphin vials, resipress vials, cysteine injection, and even business development opportunities that I won't go into detail today. Despite the stacked pipeline of potential 2022 product launches, we are not satisfied and are not coasting. We continue to aggressively hunt for new high-return product opportunities. Obviously, there's no guarantee that any transactions will close, but we are actively engaged in discussions on a number of opportunities, not just development but even commercial, that could further expand our rare disease footprint. We believe we are sufficiently capitalized to deliver on product launches and continue investment in new products for long-term growth. We finished the quarter with more than $15 million in cash. Our burn is shrinking by the month with a rapid growth. And in addition, we are set to receive a toll of $10 million of milestone payments in the coming months if Zonisamide and Lamotrigine are launched as we expect. Absent of any large new product acquisition opportunities, we do not see any need for a capital raise. Now I will turn it over to our new CFO, James Gruber, who is on the call for the first time today. James was previously the U.S. controller at Horizon Therapeutics, one of the most successful rare disease companies in the industry. During his tenure at Horizon, the company grew revenue more than tenfold, so he has shown he can successfully manage accounting and finance departments at a rapidly growing pharmaceutical company. We are happy to have him joining the team, and we believe he will see similar growth during his tenure here at Eaton. We are, of course, sad to see Wilson retire as CFO. He's been an instrumental part of the company for our entire five-year existence and has certainly earned his retirement. He was one of the founding members of our team. Wilson will be around until the end of the month to ensure a seamless transition, and he will also be consulting over the subsequent months. So with that, I will now turn it over to James to discuss our financial results. James? Thank you, Sean. Thank you, Sean.

Eaton reported product revenue of 2.2 million for the first quarter of 2022, which is an increase of 1.8 million over the 0.4 million of product revenue reported in the first quarter of 2021. Q1 of 2021 also included 11.5 million of licensing revenue, primarily from Missouri Pharmaceuticals, while there was no licensing revenue in the first quarter of 2022. Eaton's gross profit for Q1 of 2022 was $1.4 million and reflected continued growth of our Alkindi Sprinkled product as well as the launch of perglymic acid. The gross product on product revenue for the prior year quarter was $0.3 million and gross profit on licensing revenue was $10 million in Q1 of 2021. Research and development expenses for the first quarter of 2022 were $1.6 million compared to $0.9 million in the prior year period. R&D expenses in the first quarter of 2022 included a $0.5 million payment triggered by a successful development milestone on our hydrocortisone autoinjector product and continued development of our other new product candidates. Selling, general, and administrative expenses for the first quarter of 2022 were $4.9 million, which was $0.8 million higher than the $4.1 million in the first quarter of 2021. Q1 of 2022 expenses included increased sales and quality assurance activities supporting the growing commercial landscape at Eaton, along with increased legal expenses compared to the prior year quarter. As a result of these factors, Eaton reported a net loss of $5.4 million for the first quarter of 2022, compared to net income of $5.1 million in the prior year period. Eaton reported diluted earnings per share of negative 21 cents in the first quarter of 2022 compared to positive 19 cents per share in the first quarter of 2021. Cash and cash equivalents were $15.2 million as of March 31, 2022. That concludes our first quarter remarks, and with that, we're happy to take questions. Operator?

Thank you. As a reminder, ladies and gentlemen, if you have a question, please press star, then 1 on your telephone. If your question has been answered or you wish to remove yourself from the queue, please press the pound key. Once again, to ask a question, that's star, then 1. Our first question comes from the line of Ram Selvaraju with AC Wainwright.

Hi, this is Mitchell on for Ram. Thank you for taking our questions. The first one is, you know, now that you have seven products approved, Just wondering how you're thinking through the strategy for your commercial efforts and about allocating resources.

Sure. You know, I think the key for us is we have, for the rare disease products, we're going to continue to focus on that as a company. That is really where we want to allocate resources for the sales and marketing team. As we grow that out, we'll add another product like, you know, for example, a coagulamic acid we added. We have a dedicated sales force for that product. As we add another orphan drug product, we'll likely have a dedicated sales force for that. In some instances, it makes sense to partner, you know, so we do this promotional, this co-promotional arrangement with Tomar because that was what was required. So we really want to look at each product individually, but I don't expect our SG&A expenses to go up significantly. I think that, you know, as a small company, sometimes you give up longer-term value in order for shorter-term value, and that's important for us because as we grow, we have to be able to grow for the short term and do that successfully, and that ultimately will position us long-term, but you don't always maximize, you know, the... the NPV or the present value by always partnering, but sometimes it's the right thing to do. I hope that answered your question.

Yeah, absolutely. Thank you very much. And then the second question we have is just thinking about kind of the business development opportunities ahead. And if you could just elaborate on kind of the potential search for rare disease products and what fits well, and also just kind of when you hit a critical mass of what you can handle.

Sure. We, um, We would expect to close a deal, let's say in the next three months, I would say. I mean, we're in multiple conversations, so it could be, there's no guarantee, but we would expect to close a deal in the next three months, which would add another commercial product to our revenue base. We're looking for products which are strategic and really position us more and more into the rare disease space. That's where we want to be. We probably won't do too many hospital products in the future, so that business will probably have a lower percentage of sales compared to the rare disease drugs. We don't look for early stage drugs. We typically will look for late stage, so something that can be filed or launched in a 24-month period, ideally 12. And then the best scenario really is to look at commercial products where we can add value. So there's some large companies, for example, that might have an orphan drug they just don't promote because it wouldn't be significant even if they put an entire sales team behind it as a percentage of their overall revenue, and that might be a good fit for us where we're willing to do that because it's more meaningful. So those are the types of opportunities we'll continue to look at and that we are actually in conversations with.

Great. Thank you for taking our questions.

Sure. My pleasure. Thank you. Once again, if you have a question, please press star 1. Our next question comes from the line of Justin Walsh with B. Riley.

Hi. Thanks for taking the question. Just one for me. I'm wondering if you can expand on any feedback you've gotten from customers with respect to interest in purchasing the BioOrphan and or ResiPres vials once approved and how that feeds into your expectations for sales there.

Yeah, I think that's a good question, actually. We have been approached by more than three companies for that franchise. I think that they see the value in that. It's not out of the question because it's become the hospital business is a little bit non-core for what we want to do. It probably is more of a core strategy for other companies, but we still believe that is a very strong business overall with the demand that we've seen and then the shift. And the fact is the hospitals, which were reluctant to buy ampoules, are buying them more and more every month. Every month we're setting a new record on biorphine, which was not really expected, but it's been happening. And we really can feel that switch to the vial is going to happen in a big way. So I see that as well. And we think this franchise will have some robustness to it long term. for a variety of reasons, which I won't go into too much detail on that, but we think it'll be robust. It'll be a product that will see revenue, significant growth over the years to come. And if what our research has shown is that the majority, more than 80% of the hospitals, will switch to the ready-to-use vial immediately versus buying compounded products, which have no safety or efficacy shown or demonstrated, we believe they will switch quickly. So I think that product is really going to take off.

Great. Thanks for taking the question.

Sure.

Thank you. And I'm showing no further questions on the phone line. I'll now turn it back to David Crempa for any emailed questions.

Thank you, Operator. Most of the questions were asked. We have one here about how do you feel about our cash position. I'll let James answer that. Sure.

We're in good shape overall, our burn rate. Current burn rate is expected to decrease as we move throughout the year with continued growth of our on-market products. As Sean mentioned, we do expect to receive two $5 million milestones in the second half of 2022. So that being said, we should end the year with approximately $10 million of cash on hand, which still allows us some flexibility to continue to look for new product opportunities. Great.

That concludes our questions. Thank you everyone for joining us today.

Ladies and gentlemen, this concludes today's conference call. Thank you for participating and you may now disconnect.
