Piper Sandler 35th Annual Healthcare Conference

Nov 29, 2023

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

All right, we're gonna get started. Good afternoon, everyone. David Amsellem from the Piper Sandler pharma team, and welcome again to day two of the Piper Sandler Healthcare Conference. I should say 35th Annual Piper Sandler Healthcare Conference.

Paul Edick
CEO, Xeris

Anniversary.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah, 30. It's a big one. Yeah, a big round number. And with us, we have Xeris and Paul Edick. Thanks so much for CEO Paul Edick. Thanks so much for joining us. And I'll just jump right into questions, if that's okay.

Paul Edick
CEO, Xeris

Good. Uh-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

So I'll start off with, high level. You know, you've got Gvoke, you've got Keveyis, you've got Recorlev, and, we're moving towards, profitability. So I wanted to get your latest and greatest thoughts on, your profitability targets, when you expect to get there, and ultimately, talk to, how you're getting there. Is that continued Gvoke growth? Is it stability for Keveyis? Is it Recorlev growth? Is it a combination of all those things?

Paul Edick
CEO, Xeris

Okay, you know, there's like six questions in there, right?

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

That's how it is.

Paul Edick
CEO, Xeris

Okay.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah.

Paul Edick
CEO, Xeris

So the most important thing for me to clarify is our goal is sustainability.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

That, you know, we don't want to be in the market raising capital to run our business, and we don't anticipate, and we have no plans to. We have today a sustainable business based on what you just described.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

We will have, going forward, a sustainable business without having to raise capital. We've decreased our burn from $100+ million last year to $50-some million this year. It'll go down again next year. Net next year, will we have a modest burn? Maybe.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

It depends on how we invest in the business.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

Profitability is an important goal. We want to get there, but we want to get there in a way that we're continuing to fuel and foster growth in our business. As you know, we add sales force when it's opportunistic. We're potentially would like to bring a couple things through the pipeline into development. Gvoke, Recorlev, and Keveyis, to some degree, are going to continue to grow, Gvoke and Recorlev being the real drivers.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

But we've done an amazing job with Keveyis and grown it. In fact, triggered the CVR in the third quarter when it was a full year CVR. So the health of the commercial business, continuing to invest, driving our pipeline, and the partnership opportunity, I think is a, the potential future catalyst.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yep. I'll get to the partnership stuff sort of at the end. Want to talk about the your commercial portfolio. Let's cover Gvoke. So overall, glucagon rescue market growth, is it mainly been a Type 1 diabetes market? Are you getting more traction in Type 2 patients? Just help us understand the dynamics there that's driving that business forward.

Paul Edick
CEO, Xeris

Almost all Type 1 at this point.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

All Type 1.

Paul Edick
CEO, Xeris

Almost all.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay.

Paul Edick
CEO, Xeris

We're starting to get some traction in Type 2. As we increase our footprint and increase, you know, the breadth of our coverage, especially, we just added a few more of the inside salespeople-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

... to get to more of the primary care audience and working with the associations and next year with ADA, to try to take the message more to primary care.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

We're gonna start getting more Type 2, and the message, which ADA and others are starting to convey, is if you're on insulin or sulfonylureas, which is predominantly Type 2-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

... you should have a ready-to-use rescue glucagon on hand. And that population is easily 15 million people.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

Less than 1 million actually have a rescue glucagon today-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay

Paul Edick
CEO, Xeris

... which is an important, you know, all the guidelines have changed because they recognize that's not a good thing.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

And ADA is very much behind that message at this point. And the market growth, we're driving it all right now. Hopefully, as competitors, you know, start driving it also, that market growth will get back to where it was pre-pandemic, which is in the 30% range.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah. Do you think the COVID dynamics really stalled the penetration in Type 2, or is there something else that's sort of proving to be a barrier to wider adoption among Type 2s?

Paul Edick
CEO, Xeris

I think the barrier has always been a belief system that...

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

... technology, better insulins, you know, better CGMs, et cetera, was going to solve the issue of severe hypo, and it really hasn't. The rates of severe hypo, hospitalizations, emergency room visits, deaths every year-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm

Paul Edick
CEO, Xeris

... hasn't changed in decades. What really slowed the market growth, as it did for a lot of pharmaceutical categories-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm

Paul Edick
CEO, Xeris

... was two and a half years of pandemic-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah

Paul Edick
CEO, Xeris

... and not being able to call on doctors. What you're seeing now is we're back to double-digit growth, mid-teens, mid to high teens.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

You know, both products, both of the ready-to-use products continue to grow. The market continues to grow. The legacy kits is down below 20% now.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

Even Novo has announced that they're gonna discontinue their kit.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

I think everything's moving in the right direction.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Does Amphastar coming into the market and Lilly exiting on, on Baqsimi, is that a good thing or a net neutral or a negative? Or more... Or maybe I'll put it differently. Do you kind of want Lilly to be in the market just because they are, they are a diabetes leader?

Paul Edick
CEO, Xeris

Well, we wanted more voice, period.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah. Right.

Paul Edick
CEO, Xeris

So whether it's Lilly or whether it's Amphastar, the concern getting to those other 14 million people, you need more voice saying, "Hey, if you're on insulin, you're on sulfonylurea, you should absolutely have a rescue glucagon handy." So that's a positive. If it was Lilly and they were loud, that's an incremental positive-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

because they have a large position in the marketplace. What we're hoping is that Amphastar is going to be an aggressive commercial business behind Baqsimi. And that they're gonna focus on driving market growth, and if they do, everybody will benefit, especially the patients.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yep. I think you talked a little bit about sales force sizing.

Paul Edick
CEO, Xeris

Mm-hmm.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

and you mentioned inside sales. What's your headcount right now? Do you expect more expansion down the road? And just remind us how many practitioners you're targeting.

Paul Edick
CEO, Xeris

Well, the target in terms of number of practitioners we target changes every day. We've got 100 people on Gvoke in the field.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

We have 30 on Recorlev in the field. We have 20 on Keveyis in the field, with all the requisite support and marketing, et cetera, behind them. We've now upsized the inside sales group.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay

Paul Edick
CEO, Xeris

... to about 50. And, you know, that's a group that we put in place during the pandemic. Because everybody was going virtual. You had to be virtual.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

We found it to be very efficient, very effective, and about a third of the cost. You know, when you have natural turnover in a field sales organization.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

The cost of that turnover is high. We use the inside sales group as a training ground to backfill our field sales, so the cost of replacing people who move or get promoted is a hell of a lot less.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah. Okay, that's helpful. And then just lastly, on Gvoke, the payer landscape. I mean, we haven't really talked about it much, but any changes, anything to think about there?

Paul Edick
CEO, Xeris

No. It fluctuates, depending... But we've been as high as low 80% range-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

In terms of covered lives. I think we've settled in at around 70%-75% of covered lives when you look at commercial and Medicare. We don't have as much Medicaid. We just, we're not in the paid population as much.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

in any pharmaceutical category, over 70% of covered lives in commercial and Medicare is really good.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay. So let's move on to Recorlev. Maybe talk to the overall patient mix here. I know there's a lot of, you know, different, you know, modalities and patients go on and off different agents, but are you, are you getting treatment-naive patients? Are you seeing patients who are on, who've been on previous therapies, including racemic ketoconazole? Just talk to what you're seeing in the field there.

Paul Edick
CEO, Xeris

Yeah. Early on-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah

Paul Edick
CEO, Xeris

... predominantly, patients who did not do well on something or the churn, the patients that were changing therapies or physicians were changing therapies. We're actually starting to see more recently, drug naive, the patients who've not been on a previous therapy-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

... which is a really good sign because physicians who've tried Recorlev and got comfortable with getting the efficacy they want, seeing a very low incidence of side effects, beginning to use it first line, that's a really good thing. First-line use creates incremental barriers with payers-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

- because they hate that.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

So, you know, and what you'll see is you'll see some variability on a quarter-to-quarter basis in terms of the percentage of referrals that are converted to patients on drug. Referrals continue to grow very nicely, and it's like a linear curve. It's a lot of referrals.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

The time to convert that referral into a patient on drug varies.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

It sometimes takes longer, sometimes it's shorter. If we get a lot of those conversions early in the quarter, it's a really good quarter.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

If we get a lot of those conversions later in the quarter, it isn't. It's still growth, but it's not quite, quite the same. So you're seeing a little stair step.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

On average, how long does it take for a script to actually get in the hands of a patient?

Paul Edick
CEO, Xeris

A referral to turn into-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Referral to-

Paul Edick
CEO, Xeris

- a patient on drug?

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah.

Paul Edick
CEO, Xeris

Could take a month.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

Could take three or four months.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

Because there's a series of tests they have to do. They have to get an EKG before the... Then we have to clear insurance.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yep.

Paul Edick
CEO, Xeris

If it's a community-based endocrinologist, they might not have an EKG machine. You've got to schedule that. So, you know, that takes time. If you, you know, doctor's offices are full, you can't get an appointment the next day, so it's highly variable. Let's put it that way.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

So what does the payer landscape look like? I mean, in terms of, you know, ease of access and what different payers are requiring.

Paul Edick
CEO, Xeris

Yeah, you're in rare disease.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah.

Paul Edick
CEO, Xeris

Almost virtually, everybody's a prior authorization.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

So you have to go through the prior authorization process. The degree to which that prior authorization and the referral are filled out completely, you know, based on the physician, you're going to go to a payer, and you're gonna get a rejection for some reason. Then you've got to go through an appeal, and that all goes to the quality of the referral and the prior authorization coming out of the physician's office in the first place.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

Some do it really well, some don't do it so well.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah.

Paul Edick
CEO, Xeris

So, you know, we've got case managers, patient assistance managers, and a specialty pharmacy all working with the offices to try to improve and increase the quality of the referral, the quality of the PA, in order to get faster reimbursement. That being said, on average, depending on the quarter, we're clearing 50%, sometimes as high as 60% of the referrals are cleared for insurance, which is pretty good if you think about the conversation we had about Gvoke.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

70%-75% of covered lives is really good. To clear 50%-60% of referrals in a rare disease is excellent.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

In terms of the payer landscape, are you seeing payers want patients to have exposure to racemic ketoconazole? Has that happened in some cases?

Paul Edick
CEO, Xeris

Not to the degree that people would have assumed we would.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay.

Paul Edick
CEO, Xeris

You know, bottom line is they you know, physicians recognize they'd rather use an approved drug that's got a clinical package and you know, has a label.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah.

Paul Edick
CEO, Xeris

To some degree, are we still having to step through ketoconazole? Sure.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

It's been out there for a long time.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

A lot of patients have been on it. The good news is a lot of patients have already been on it. They've already failed it. So the step-through is almost a built-in. You know, if somebody asks us to step through Signifor, it's a harder hurdle. It's a higher hurdle-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right

Paul Edick
CEO, Xeris

... 'cause not that many people are on it.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right.

Paul Edick
CEO, Xeris

So it's both a blessing and a curse all at the same time.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

So, I know it's early days. The product hasn't been on the market all that long, but do you have a good read on discontinuations or patient persistence?

Paul Edick
CEO, Xeris

Discontinuations are very low.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay.

Paul Edick
CEO, Xeris

We've had, you know, a handful.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

These are sickly patients for the most part.

Paul Edick
CEO, Xeris

Yeah, and your point, it's early days. We will have-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure

Paul Edick
CEO, Xeris

...discontinuations because patients, they're—these are not well. They're sick people.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

They don't necessarily do well on everything. You know, we will. It's just we haven't seen many so far.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

So, from thinking about... I don't want to get too caught up on, you know, the near term in the fourth quarter, but if I'm hearing you correctly, you're getting these starts.

Paul Edick
CEO, Xeris

Mm-hmm.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

You know, the cycle from referral to script is variable, so that's a big wild card. It's -- we're trying to handicap, you know, 4Q and going into 1Q. I mean, are there any other dynamics that we should be mindful of, you know, that might swing, you know, sales in the fourth quarter one way or another, you know?

Paul Edick
CEO, Xeris

I don't think so.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay.

Paul Edick
CEO, Xeris

It's... It really is the dynamic that I described.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay.

Paul Edick
CEO, Xeris

If the referrals are pretty, remain very strong. If we convert a lot of those referrals to patients on drug early, like, in October, November-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

... it'll be a bigger quarter. If a lot of those patients get converted into drug in October or November, December, it'll be a good growth quarter, but maybe not quite as big. And that's why, you know, you saw a really big jump second to third, a nice jump, or first to second, and then a nice jump second to third, but not quite as big.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

That's just that stairstep that we're gonna go through.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right.

Paul Edick
CEO, Xeris

That's gonna be a long term, and it's on a small end.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

If you draw a line through that, it's really nice continued growth.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay, that's helpful. But let's move on to Keveyis. The product hung in there reasonably well, even with a generic. You don't see that very often.

Paul Edick
CEO, Xeris

Yeah.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

So talk about the dynamics of that Keveyis that make it unique and might explain why it's been resilient.

Paul Edick
CEO, Xeris

It's been more than resilient.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

It's remarkable.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah.

Paul Edick
CEO, Xeris

And the fact that we have grown Keveyis significantly-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

... you know, materially, in the face of a generic for a year, I think is outstanding. What accounts for that is we surround every one of those patients. So we find the patients to begin with.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

We surround them with services, case managers to help them with insurance, patient managers to help them with their physician interactions and the pharmacy interactions, and mentors, so patients who are on Keveyis-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

... who've been through the process to help them kinda work their way through it. And remember, the process is, to some degree, reentering society.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

These are people who've become housebound.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

Because you can't go to dinner or drive a car not knowing when you suddenly would be paralyzed. Okay? Driving a car, paralyzed, bad. Okay?

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah.

Paul Edick
CEO, Xeris

Patients who've been through that experience as a mentor, you combine all of that, physicians are willing to fight for brand-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

... to be able to give patients the opportunity to have all that service. Patients that we've lost, that have had to go to generic, several of them have come back.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

Okay? And so it's that dynamic, which is unique to a drug like Keveyis, you can't do this in every category, has allowed us to not only maintain it, which we said when we bought Strongbridge, we believe we can maintain this business.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

We've grown it. How well we can maintain it in the future with one generic, we think we can still be able to do it well.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

We might lose some patients because of payers. If there's another generic, that changes the dynamic, but we believe that this is still gonna be a very positive contributor for years to come.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Now, my understanding is the generic is changing hands, and that I don't know off the top of my head the company that's now taking it over, but I believe it's going to be more of a brand generic going forward, or at least that's what it seems like.

Paul Edick
CEO, Xeris

Yeah.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

So how does that change things for you, or what are you hearing?

Paul Edick
CEO, Xeris

Yeah. I don't know the specifics either, because-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah

Paul Edick
CEO, Xeris

... you know, people don't call us up and tell us that.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

Torrent is moving the product to more of a branded generic distributor to help them with the commercialization.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right.

Paul Edick
CEO, Xeris

'Cause obviously, it has not gone well.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

To some degree, I think you're right. It could be a very good thing because it is more of a branded generic player.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm.

Paul Edick
CEO, Xeris

It isn't a chase the price to the bottom kind of company-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right

Paul Edick
CEO, Xeris

- which I think will be good. Whether they are going to participate in the identification of patients to grow the category, I think that's, the jury is still out on that.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah, and I guess that brings me to my next question, is how penetrated is Keveyis in primary periodic paralysis? And you know, what does the pace of new starts look like?

Paul Edick
CEO, Xeris

I don't think, I don't think we really have a great handle on how penetrated it is.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah.

Paul Edick
CEO, Xeris

We believe that there are several thousand of those, these patients out there.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

If you look at the historical, you know, how many patients have actually been on drug for at one time or another, it could be 2,000-3,000 patients.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

So I think there, there's still a great opportunity. You know, how well we can penetrate that in the future, I don't know.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay. But there's... I mean, if I'm thinking about this the right way, there's, this is a market that can grow. I mean, is that a fair way to think about it?

Paul Edick
CEO, Xeris

Well, it's a category of patients that is probably pretty stable.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay.

Paul Edick
CEO, Xeris

But the penetration can improve.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay. Fair enough. So in the five minutes we have remaining, I wanted to touch on pipeline and partnerships and, you know, one product that you've been talking about is your injectable levothyroxine product. So just help us frame the value proposition here. I mean, this is a very big oral solid market.

Paul Edick
CEO, Xeris

Mm-hmm.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

There's a number of generics here. So why does an injectable Levothyroxine... or what does an injectable Levothyroxine product add to the-

Paul Edick
CEO, Xeris

Yeah

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

to this, to this category?

Paul Edick
CEO, Xeris

Yeah. What you're describing is very counterintuitive.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right.

Paul Edick
CEO, Xeris

Right? You wouldn't expect you go, you know, you go from a liquid to a daily oral, right?

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

But that daily oral, the population of people on levothyroxine is huge.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

It's over 100 million prescriptions a year, and there is a percentage of that population that either they have pretty serious gastrointestinal side effects or malabsorption, which creates a variability in blood levels, which we believe is better part of 25% of the population.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

Okay? Which, a drug this big, that's a lot of people.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

Evidence of that is in the phase II study we're currently doing. We're trying to finalize the dose conversion from oral to liquid.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

What we're finding is trying to do a study with stable Synthroid patients-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

is incredibly hard because most of the screen failure of is through the roof.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right.

Paul Edick
CEO, Xeris

For every 10 or 20 people we screen, we get one patient that actually goes on drug-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

- which says there are a lot of patients that aren't doing very well on the oral.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right.

Paul Edick
CEO, Xeris

If we can bypass the gut in a five-second subcutaneous injection-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

- once a week, you capture that, a big percentage of those people. At today's price, today's generic Synthroid price-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

If you multiply it by seven days, that percent, that slice of the market could be worth $2 billion-$3 billion. Okay, so I'll take a piece of that.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yep.

Paul Edick
CEO, Xeris

Okay, and our market research, limited so far, we've yet to bump into a patient who's experiencing those problems who said, "I wouldn't want a once-weekly subQ injection.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay, um-

Paul Edick
CEO, Xeris

I think it's a great opportunity.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

You have your phase II.

Paul Edick
CEO, Xeris

Mm-hmm.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Can you just walk through quickly the design and the trial?

Paul Edick
CEO, Xeris

It's pretty simple.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah.

Paul Edick
CEO, Xeris

It's stable... people who are stable on Synthroid-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yep

Paul Edick
CEO, Xeris

- to see what the conversion rate, the conversion is from oral to liquid. And in our modeling that we presented to the FDA on, non-drug taking patients-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

No, you know, like, healthy volunteers, it was four-to-one. What we're trying to determine for the FDA, per, per their directive-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

is do it on drug-taking patients.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

- who are active, you know, Syn, and across more doses-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah

Paul Edick
CEO, Xeris

- so that we can see that the conversion is the same at any dose. And if you, if you look at it, there's, like, 12 different doses of levothyroxine-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure

Paul Edick
CEO, Xeris

- out there, oral.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yep.

Paul Edick
CEO, Xeris

It's to... And that will inform a phase III.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay. What, what would a phase III look like? I mean, would it basically be also PK parameters?

Paul Edick
CEO, Xeris

TSH, its endpoint of TSH is what the FDA wants.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay.

Paul Edick
CEO, Xeris

They haven't gotten that from a lot of sponsors historically.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right.

Paul Edick
CEO, Xeris

We included that in the phase II because we know they're gonna want that.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

We could very easily argue, "You haven't done it, haven't made anybody else do that, but why should we?" But I think it's an endpoint that's worth doing. It's the correct endpoint, and, you know, that's where we should be in terms of helping the FDA further, what they're trying to do in terms of how they review these drugs. The question is going to be: How many patients?

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

How long is that gonna take?

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right.

Paul Edick
CEO, Xeris

Is it all comers or people who are stable on... stable or unstable?

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

So-

Paul Edick
CEO, Xeris

Is it Synthroid, or is it anybody?

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

I know that there's still a lot of questions outstanding, but, you know, what's a realistic case for when commercialization can happen? Is it 2027, 2028?

Paul Edick
CEO, Xeris

Yeah.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

I mean, is that the right way to think about it?

Paul Edick
CEO, Xeris

Probably late 2027, 2028.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay.

Paul Edick
CEO, Xeris

Part of the rate-limiting step is the dial-a-dose pen-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yep

Paul Edick
CEO, Xeris

- that you have to be able to dial 12 different dosages.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay.

Paul Edick
CEO, Xeris

That's the development timeline for those devices is considerable.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay. So this will be a patent?

Paul Edick
CEO, Xeris

Oh, yeah.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Nothing else but... Okay. Okay, that's helpful. And then we have about 30 seconds left. Just you've got the $6 million milestone on the subQ form of,-

Paul Edick
CEO, Xeris

Yes

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

- Tepezza. What are the next steps there? I know that's one partnership that-

Paul Edick
CEO, Xeris

Well, yeah

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

You know, we're-

Paul Edick
CEO, Xeris

Amgen just closed their deal, and they're gonna review all of what's going on in Horizon.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

They'll make a decision on whether they want to continue clinical development of-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

- the XeriJect Tepezza.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay, what would your royalties be on that to the extent-

Paul Edick
CEO, Xeris

Yeah

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

that it's commercialized?

Paul Edick
CEO, Xeris

We haven't disclosed value.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm.

Paul Edick
CEO, Xeris

until we get a license, it doesn't really make sense to de-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure

Paul Edick
CEO, Xeris

to talk about it. But with a license, we would get clinical milestones, regulatory milestones, commercial milestones, and royalties that one could argue, if you look at marketplace deals, market-sized deals-

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Mm-hmm

Paul Edick
CEO, Xeris

- pretty substantial.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

One last one, I know we're out of time. Just real quick, any other partnerships that we should be keeping an eye on?

Paul Edick
CEO, Xeris

I think the Regeneron platform deal is important.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Yeah.

Paul Edick
CEO, Xeris

They're gonna put a number of assets into our technology. We have successfully formulated for them multiple assets in the past.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Right.

Paul Edick
CEO, Xeris

I think that... and Regeneron is not a company that does third-party deals very often.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Sure.

Paul Edick
CEO, Xeris

I think that's an important one.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

All right. We'll keep an eye on it. Thanks, Paul. Thanks, everyone in the audience.

Paul Edick
CEO, Xeris

Thank you.

David Amsellem
Managing Director and Senior Research Analyst in Biotechnology, Piper Sandler

Okay.
