Good morning or good afternoon, and welcome to the Xeris Biopharma third quarter 2022 financial results call. My name is Adam, and I'll be your operator today. If you'd like to ask a question during the Q&A portion of today's call, you may do so by pressing star followed by one on your telephone keypad. I will now hand the floor over to Allison Wey, Senior Vice President of Investor Relations and Corporate Communications, to begin. Allison, please go ahead when you are ready.
Thank you, Adam. Good morning, and welcome to Xeris Biopharma's third quarter 2022 financial results and corporate update conference call and webcast. A press release with the company's third quarter 2022 financial results was issued earlier this morning and can be found on our website. We're joined this morning by Paul Edick, Chairman and CEO, and Steve Pieper, our CFO. Paul will provide opening remarks. Steve will provide details on our financial results, and after a few closing remarks by Paul, we'll open up the call for Q&A.
Before we begin, I would like to remind you that this call will contain forward-looking statements concerning Xeris' business practices, Xeris' future expectations, plans, prospects, clinical approvals, commercialization, corporate strategy, performance, and the impact of COVID-19 on Xeris' business practices, which constitute forward-looking statements for the purposes of the Safe Harbor provision under the Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those indicated by these forward-looking statements as a result of various important factors, including the effect of uncertainties related to the COVID-19 pandemic on U.S. and global markets, Xeris' business, financial condition, operations, clinical trials, third-party suppliers and manufacturers, and other risk factors including those discussed in our filings with the SEC.
In addition, any forward-looking statements represent our views only as of the date of this call and should not be relied upon as representing our views as any subsequent date. We specifically disclaim any obligations to update such statements. I will now turn the call over to Paul.
Thanks, Allison. Good morning, everyone, and thank you for joining us today. Before getting into the results of the quarter, I wanna reiterate a few things we talked about on our second quarter call regarding what we're trying to build at Xeris. Number one, the most important aspect of building multiple successful companies as a team over the years has been knowing where we are, where we wanna be, how we plan to get there, and executing against that strategy with absolute clarity. We have evolved considerably over the last few years, growing from a development company with one end of phase two asset and two very unique technologies to a full-fledged commercial business with three growing products, targeted pipeline development, and potentially meaningful technology partnerships.
Reiterating what I said on the second quarter call, where we want to be and what we focus on at the beginning and end of each day is building a substantial, patient-centric, commercially focused, self-sustaining biopharma enterprise with multiple products in multiple therapeutic areas, a highly targeted development pipeline that has significant long-term promise and increasingly value-added technology partnerships. What you will hear today is that we are continuing to progress very successfully on that journey. We are executing on our vision. Our 2022 momentum continued through the third quarter and into the early part of the fourth quarter. We continued delivering record growth and patient demand and net revenues for all three of our marketed products through the quarter. We also continued advancement of our levothyroxine pipeline program.
With the solid year-to-date performance of all three products and the disciplined management of expenses and cash, we are confident we can achieve the following. As I've said on previous calls, I believe that a result at any point in our range of net product revenue guidance would be an exceptional commercial performance of 2022. At this point in the year, we have a good line of sight to where we may end the year and are thus narrowing our net product revenue guidance from $105 million-$120 million to $105 million-$110 million. At the same time, we are raising the previous year-end 2022 cash balance guidance, which was $90 million-$110 million and is now $110 million-$120 million in cash.
We are reiterating our expectation that our cash position is adequate to fund our operations to cash flow break even, currently expected to happen by year-end 2023, without the need to tap the equity markets for the purpose of funding ongoing operations. Now, I'll go into some specific highlights for each product behind this performance. Gvoke had another strong quarterly performance with record revenues and prescriptions. Gvoke net revenue in the third quarter was a record $13.7 million, a 24% increase compared to Q3 last year and a 19% increase from last quarter. Year to date, Gvoke net revenues increased 35% compared to the same period last year. In the third quarter, Gvoke total prescriptions were over 38,000, growing more than 40% compared to the same period last year.
Year to date, Gvoke total prescriptions were over 103,000, growing approximately 60% compared to the same period in 2021. The total glucagon market grew an additional 9% in the third quarter versus prior year, fueled considerably by Gvoke's performance. Gvoke continues to outpace and drive market growth quarter after quarter. Gvoke's market share grew to approximately 24% at the end of October, and the ready-to-use glucagon products are now approximately 70% of the glucagon market. It's great to see that more and more people with diabetes who are on insulin, and therefore at serious risk of a severe low blood sugar event, are getting a ready-to-use glucagon prescription such as Gvoke. However, we have a long way to go until all patients on insulin who are all at high risk have a ready-to-use Gvoke available just in case.
Moving to Keveyis. Keveyis had another record quarter with $13.4 million in net revenue, an increase excuse me, of approximately 17% compared to third quarter 2021, and an increase of 4% from last quarter. Year-to-date, Keveyis net revenue has grown 19% over the same period in 2021 on a pro forma basis. Comparing third quarter 2022 to third quarter 2021, we saw a 9% increase in patient demand. In 2022, on a year-to-date basis, patient demand has increased 10% compared to the same period in 2021. Looking at Recorlev, during the quarter, we continued to generate a meaningful number of patient referrals and an increase in number of patients starting on therapy. We're also seeing patients that have started on therapy begin to titrate up their average daily dose, which is a very good sign.
This performance resulted in $2.5 million in net revenue for the third quarter, a 160% revenue growth from the second quarter. It's still very early in the launch of Recorlev, but Recorlev continues to grow and show great long-term growth potential. Now I'd like to turn to XeriSol levothyroxine. A few weeks ago, we reported very encouraging results from the phase I pharmacokinetic comparison of oral Synthroid versus subcutaneous XP-8121, our small volume, ready-to-use formulation of levothyroxine utilizing our XeriSol technology. The study results offer initial proof of concept that our novel subcutaneous formulation of levothyroxine has the potential to provide patients with a once-weekly dosing, potentially improving treatment adherence, as well as bypassing the gastrointestinal tract and mitigating the limitations of oral therapy. Excuse me.
In the first phase of the study, we compared single 600 microgram doses in a crossover design with normal volunteers. Subcutaneous XP-8121 provided a lower maximum concentration or Cmax, longer time to maximum concentration or Tmax, and a more sustained exposure profile relative to oral Synthroid. We continued the study with two additional ascending doses of XP-8121, and we confirmed linear dose proportionality between 600, 1200, and 1500 micrograms. Throughout the course of the study, no major safety concerns were identified. All data from this phase I study were then combined to develop a population pharmacokinetic model. This model allowed us to perform simulations of various chronic dosing scenarios.
Based on comparable exposure at steady state, the model estimated that 1,200 micrograms of once-weekly XP-8121 could provide similar exposure to 300 micrograms of daily oral Synthroid, implying a 4x conversion factor between once daily and once weekly dosing. At present, the FDA has granted our request for a Type C meeting to review our phase 1 data and proposal for a single phase II/III registration study and other requirements to enable an NDA. We expect their feedback by the end of this year. Our regulatory strategy is based on FDA's previous findings of safety and effectiveness for Synthroid, FDA-published guidance for in vivo pharmacokinetic assessment of levothyroxine products, and precedent FDA approvals for products comparing daily oral versus weekly or longer administration. Our levothyroxine has been the standard. Excuse me.
Oral levothyroxine has been the standard of care treatment for hypothyroidism for several decades. While generally safe and effective, oral levothyroxine presents several challenges to hypothyroid patients in managing their condition, including inadequate absorption of levothyroxine in the gastrointestinal tract, either due to a concomitant GI condition or interfering concomitant medications, as well as compliance issues. Levothyroxine patients remain in need of improved treatment options. Yet levothyroxine remains one of the most prescribed medicines in the United States, with over 100 million prescriptions dispensed every year. What does this mean in terms of a potential market opportunity? Conservatively, if we take 10% of those patients with multiple issues, as I've described, or approximately 7 million prescriptions of this market at current branded pricing, this could be a $2 billion-$3 billion market segment in which we believe our once-weekly subcutaneous levothyroxine could compete very effectively.
I know that's a mouthful on levothyroxine, but I think it's important for us to detail that once again. At this point, I'll turn it over to Steve for details on our financial performance.
Good morning, everyone. I will focus my remarks on a few of the key financial results, the details of which are in the press release issued this morning. Total net product revenue was a record $29.6 million for the third quarter, representing a 31% increase over the same quarter last year on a pro forma basis. This increase was driven by growth of all three of our products. Strong underlying demand, patient demand for both Gvoke and Keveyis, and new patient starts on therapy for Recorlev were the key drivers for total product revenue growth in the quarter. Breaking it down by product, Gvoke net revenue for the quarter was $13.7 million, representing a 24% increase compared to the same period last year.
This increase in revenue was driven by continued growth in prescriptions, topping 38,000 for the first time, more than a 40% increase compared to the same period in 2021. This growth in demand was partially offset by a decrease in net pricing, which I explained in detail on our last call. To be clear, we believe that our net pricing has stabilized. Year-to-date, Gvoke net revenue was $37.6 million, representing a 35% increase compared to the same period last year. This increase was again driven by growth in prescriptions, approximately a 60% increase compared to the same period in 2021, which was partially offset by a decrease in net pricing. Moving to Keveyis. Keveyis net revenue for the quarter was $13.4 million, representing a 17% increase compared to the same period last year on a pro forma basis.
On a year-to-date basis, Keveyis net revenue was $35.5 million, representing a 19% increase compared to the same period last year on a pro forma basis. We continue to see increases in the number of patients on Keveyis. These patient increases, coupled with a net pricing increase, contributed to this revenue growth. Recorlev net revenue for the quarter was $2.5 million, more than double compared to the second quarter of 2022, and a direct result of the steady growth of patients on therapy. Year-to-date, Recorlev net revenue was $3.6 million. We continue to be pleased with our initial financial performance of Recorlev, and we are also encouraged by the outlook of Recorlev given the weekly growth of new patient referrals and new patients coming on to therapy.
As Paul mentioned, we are tightening our guidance of total net product revenue of $105 million-$110 million, still within our previous range of $105 million-$120 million. Moving down to P&L, cost of goods sold increased by $7.9 million for the nine months ended September 30th compared to the same period in 2021. The increase was attributable to an increase in sales as well as product mix and increased costs. Research and development expenses increased $0.9 million, or roughly 6%, for the nine months ended September 30th compared to the same period in 2021. Consistent with prior quarters, the increase was primarily driven by higher personnel-related costs offset by lower product development costs.
Selling, general, and administrative expenses increased by $31.8 million, or roughly 45%, for the nine months ended September 30 compared to the same period in 2021. We incurred $24.2 million of increase in personnel-related costs due primarily to the Gvoke field expansion in Q3 of last year and the inclusion of our Keveyis and Recorlev commercial infrastructure, as this change is not on a pro forma basis. The company also incurred increased marketing spend driven by the launch of Recorlev. From a cash perspective, as of September 30th, Xeris had total cash equivalents, and short-term investments of $93.4 million, compared to $111.6 million at June 30th, 2022.
We continue to maintain a strong cash position, are delivering on the synergies from the Strongbridge acquisition, and have a healthy balance sheet even as we have faced inflationary headwinds. Based on our current cash position, forecasted spend, and our previous guidance to draw the additional $50 million available under our Hayfin debt facility by the end of this year, we expect to end 2022 with more cash than previously guided. We are increasing our year-end 2022 cash guidance from a range of $90 million-$110 million to a new range of $110 million-$120 million. We feel that Xeris is in a unique position with a healthy balance sheet and three growing commercial assets that we believe will ultimately lead to Xeris reaching cash flow breakeven by the end of 2023.
I will now turn the call back to Paul.
Thanks, Steve. As we finish the year and head into 2023, we expect to build upon our 2022 momentum and continue creating shareholder value through continued revenue growth, careful allocation of resources, and prudent expense management. Operator, would you please open the line for questions at this point?
Of course. As a reminder, if you'd like to ask a question today, please press star followed by one on your telephone keypad. When preparing to ask a question, please ensure your headset is fully plugged in and unmuted locally. Star followed by one to ask a question. Our first question today comes from Glen Santangelo from Jefferies. Glen, your line is open. Please go ahead.
Thanks for taking my question. Paul, I wanted to dive into the glucagon market a little bit more. You said that this quarter, the total market grew 9%. That seems, you know, it seems encouraging, but it's also a slight deceleration from where we were in 2Q, and 2Q decelerated somewhat from where we were in 1Q. I'm wondering if you could, you know, talk about that from a high level. You know, beyond that, you know, in speaking with one of your competitors who manufactures a generic legacy kit, they seem to be very excited about the fact that two of the manufacturers are gonna sunset their legacy kits here soon.
It's their view that the price differential between, you know, the ready-to-use products and the generic products aren't big enough that maybe that'll be enough to stem, you know, the tide towards these ready-to-use products. I was wondering if you could just sort of give us your assessment of this market, how you think it shapes up for 2023 given all the moving parts. Thanks.
Yeah. Thanks, Glenn. I'll take that in reverse order because I think the end of your comments are probably the most pertinent at the end of the day to kind of the dynamic in the marketplace. I would describe the legacy products relative to the new ready-to-use products as impossible to use products. There is no issue of price in this marketplace, and you can tell by the speed with which 70% of this market has gone from the legacy products to the ready-to-use products.
When I say impossible to use, when you look at the human factor studies that have been done by us and other manufacturers, in almost any study, the best outcome you could get was approximately three out of every 10 people could actually execute and deliver the proper dose using those kits. The critical need in the marketplace is a usable form factor. It's not price. What has made the difference has been the nature of the new ready-to-use products. They're easy to use for a caregiver, they're easy to use for a medical professional, and they're easy to use for self-administration. Self-administration has never really been an option because of the complicated nature of the kit and the nature of a severe hypo. People are losing cognitive function.
They can't execute the kit. I think that's critically important to how people view this market. As far as the growth, we've had growth pre and pre-pandemic that was as high as 25%-30%, and we've had consistent growth in double digits throughout the COVID period. It has been up and down, and we've had a couple of quarters where it's gone below double digit. That doesn't scare us at all. We think that's gonna reverse and continue to grow. The fact of the matter is Gvoke and Xeris are shouldering the majority of the growth that's happening in the marketplace. As Lilly gets more active with their nasal and Novo comes in, gets more active, we'll have a louder voice in the marketplace.
The bottom line is, there's 7 million people on insulin who are at high risk for a severe low that should have one of these ready-to-use products such as Gvoke. Sooner or later, that message will get through to clinicians.
Okay. Paul, maybe if I could just ask a quick follow-up on the guidance. I mean, in your prepared remarks, you seem to be, you know, suggest that anything within the original guidance range was very encouraging, and I guess I generally agree, but, you know, just sort of looking at the guidance reduction, right? You lowered the midpoint by $5 million and the top end of the range by $10 million. I'm just kind of curious as to maybe what changed in your mind, or relative to what you might have been thinking, you know, 90 days ago. Then lastly, you know, Steven, thanks for the update on the cash, but could you give us the debt number as of today? That'd be great. Thanks.
Yeah. I think the answer to your question, Glenn, was in your first question. We expected double-digit market growth to continue, and we saw high single-digit market growth. The top end of the original guidance had more substantial market growth built in.
Okay.
On the debt, you know, we currently have with Hayfin $100 million outstanding, and then we have a convert that has roughly $47 million. As I mentioned in my remarks, we plan to draw the additional $50 million available to us under the Hayfin facility. We'll have $150 million.
I would just reiterate relative to that guidance, we've said from the very beginning that with two launch products, especially Recorlev, Gvoke still being in launch mode, that we had a fairly wide guidance range, anticipating that there would be some variability. The bottom line is all three products continue to grow. They all are growing incredibly well at double digits versus prior year. I've said from the beginning, anywhere in that range would be excellent performance for us as a company.
Great. Thanks for the responses.
The next question comes from David Amsellem from Piper Sandler. David, your line is open. Please go ahead.
Hey, thanks. Just a few. First, can you talk about payer dynamics surrounding Recorlev, what you're seeing there and, you know, what you can do to continue to grow, you know, underlying patient usage? Just talk generally about what you're hearing in the field about, you know, overall receptivity to the product. If there's any, you know, patient-specific metrics or prescriber metrics that you could share, that would also be helpful. Just going back to the glucagon market. Amphastar noted that they're gonna be doubling their glucagon capacity. You know, your comments regarding the kits are not lost on me.
Is it your view that with the kits being discontinued by Novo and Lilly, that the ready-to-use products will capture the lion's share of that, or you think it'll be sort of a mix of, you know, business going to the generic kit and the ready-to-use products. I mean, ultimately, how do you see that shaking out as we move through 2023? Thanks.
Okay. Well, let me start with glucagon first again. What you've seen over the course of the last couple of years is regardless of whether Lilly or the Amphastar generic entry, et cetera, the legacy kit type of delivery has continued to decline. We believe, you know, we're seeing evidence of it in the marketplace, that the ready-to-use products like the nasal and like Gvoke are going to continue to take a greater percentage of the market. The Lilly discontinuation of their kit is a clear signal to prescribers that the biggest company in the business does not believe that that kit is an appropriate form factor for patients. You know, where the rubber meets the road is with the prescriber.
If they're prescribing the ready-to-use products, they're not gonna be converted to the old legacy generic kits. We expect that portion of the market to continue to decline, and we expect the ready-to-use to take the lion's share. You know, we've always said a little bit of it might linger, but I don't think anyone anticipated that it would be 70% in the ready-to-use in such a short period of time. In terms of Recorlev patient usage, patient usage on Recorlev is patient referrals are strong, patient initiations are strong. The difference that we're seeing is we had anticipated that people would titrate up to their optimal dose a little bit faster. You know, we're not concerned about that at all. Physicians are taking an appropriate approach to stepwise dose titration.
That's good medicine. We're working very effectively with payers, clearing insurance. Nobody gets Recorlev until the insurance is cleared. There is a process to a patient starting on Recorlev. There's the initial referral, and then the patient has to go through some testing. They need to get an EKG. Physicians are busy, patients are busy, and those repeat visits take time. We've said from the beginning that, you know, it can be weeks to months from a patient referral to an actual patient on drug. Receptivity has been outstanding. We've gotten no pushback from physicians. It's a matter of them getting a good sense of Recorlev and how they can best utilize it in their practice.
We think we've got a better product than Isturisa, which has a lot of androgenic side effects. We think we have a better product than Korlym, which when you think about it, the goal in Cushing's is to normalize cortisol. Korlym doesn't do that. We think we've got a very competitive product. In fact, we know we do, and we're encouraged by the results so far. Payer dynamics have been as expected. You know, it's a negotiation one at a time.
Okay. Helpful. Thank you.
The next question comes from Oren Livnat from H.C. Wainwright & Co. Oren, your line is open. Please go ahead.
Thanks. I have a few questions. If we could just talk big picture, you've reiterated your guidance for year-end cash flow breakeven or 2023 year-end breakeven, which I think is probably a major upside to current Street expectations. Can you just talk about, you know, the main drivers of that growth in your mind? You know, is it safe to assume that's largely year-over-year Recorlev growth in there? I guess the main drivers of that, is that versus the current trends we're seeing, is that just the conversion of a, you know, maybe a backlog of patients as they get on, you know, through insurance and that product accelerates quickly now? Or is up titration a major component of that? A couple others. Thanks.
Yeah, Oren, it is. Recorlev plays an important role in that. It is a lot about the time from referral to patient on drug. The more efficient we get at that, the better we get at that, the more we negotiate with payers, et cetera. Importantly, the rate of titration to the optimal dose. More patients getting to where they need to be over time is gonna be a pretty big driver. As well as.
Okay.
Continued growth in Gvoke.
Go ahead.
I think, yeah. Continued growth in Gvoke as well, Oren.
Okay. Following up on that Recorlev, conversion and up titration, at any point, should we expect to get numbers on, you know, patients referred and/or patients on drug, or is that gonna be something you maintain close to the vest even going forward? You talked about having a superior drug. Can you comment on just any pushback in the adjudication phase, the insurance adjudication phase with regards to off-label, ketoconazole out there? Is that an issue you face or is it just normal, we're trying to put a patient on a very expensive drug and that's a process?
It's what you just said at the end. It's trying to put a patient on a very expensive drug and it's a process. We are not getting pushback on ketoconazole because, in fact, at the physician level, we're being embraced as having something that's actually been studied has an actual label and is being detailed on label. Physicians are not comfortable using ketoconazole off-label. They just aren't. The payer is not really in a good position to require ketoconazole in order to get to Recorlev.
Okay. Just one last one on Gvoke. Aside from prescription growth, it looks like your quarter-over-quarter revenue growth was surprisingly strong. It was above our estimates. Can you confirm if there were any inventory dynamics at play, or is it just that the net price has stabilized higher than maybe where it was recognized in 2Q? I think you said that should be stable going forward.
Yeah. It stabilized in Q3, the net price. You know, assuming a consistent payer mix, Oren, I think we would expect that it to remain kind of where it leveled off in Q3. I think what we did see is, you know, relative demand. We did see a little bit of inventory build in the quarter. You know, could be going to alternate channels. Yeah, we saw a little bit of inventory build in the third quarter. You see that from time to time, so.
All right.
Particularly the, you know, back-to-school season.
Perfect. Well, thanks for the help.
The next question comes from Roanna Ruiz from SVB Securities. Raghuram, please go ahead. Your line is open.
Great. Thanks. Good morning, everyone. I did have a couple questions on Gvoke. Maybe could you talk a little bit about some of the competitive dynamics you're seeing between Gvoke and Baqsimi? Is there anything that we should expect going into the holiday months, end of this year for 4Q?
The competitive dynamics I think are pretty much as we expected. Lilly continues to promote Baqsimi. They're most active during the back-to-school season. Their you know their biggest real franchise is in pediatric endocrinologists, so that's usually when they're even more active. You know, like I said previously, and you and I have talked about, I'd like to see them a little bit even more active because they're a big voice and they can drive market growth. You know, we've got a great product, and we continue to grow our share of the ready-to-use. You know, so I think the competitive dynamic is playing out like we said at the outset. They're gonna take a bigger piece of the pie than we are early on. We're gonna close that gap somewhat.
If both products continue to grow the way they are, and continue to grow the market, we're both gonna do extremely well. It's pretty much just Lilly and us at this point. Like I said previously, the generic companies can ramp up in their manufacturing as much as they want. They have a product that patients can't use.
Yep, fair point. Wanted to ask a little bit about Recorlev. I know you talked a little about the titration going very well. I was curious if you had any insights on what you expect the overall average maintenance dose to be, like, going into 2023 as more patients ramp up. Any sort of color on that would be super helpful.
Well, what we saw in the clinical studies was patients were titrated up to most commonly 600. We expect that you know, in the practical utilization, that we'll end up somewhere in the 500-600 neighborhood. I think it's playing out that way. You also asked something about the holiday in your previous question. You asked about holiday dynamics. Nothing special except you know, people are at increased risk during the holidays based on you know, the way they eat and drink, et cetera. You know, we don't attack it in any different manner than normal.
Got it. Thanks.
We have no further questions. I'll turn the call back to Paul Edick for concluding remarks.
Thank you. I wanna personally thank all of our long, loyal shareholders and investors for their support over the last few years. We absolutely appreciate your continued belief in what we're building. We continue to work hard every day to deliver value on your investment. You can see from everything we just discussed that our business is in great shape. We continue to affirm and meet our guidance, which represents excellent continued growth year over year. We have plenty of cash, and we're managing expenses aggressively. Thanks for joining the call this morning and your continued support as we execute on our growth strategy to build a substantial, patient-centric, commercially focused, profitable biopharma enterprise. With multiple products in multiple therapeutic areas, a highly targeted development pipeline that has significant long-term promise and increasing value-added partnerships based on our unique technologies.
Meeting the needs of patients and caregivers every day. Thank you very much.
This concludes today's call. Thank you very much for your attendance. You may now disconnect your lines.
