Good day, and thank you for standing by. Welcome to Jazz Pharmaceuticals 2025 Second Quarter Earnings Conference Call. [Operator Instructions] Please be advised that today's conference is being recorded. I would now like to hand the conference over to your first speaker today, Jack Spinks, Executive Director of Investor Relations.

Thank you, operator, and good afternoon, everyone. Today, Jazz Pharmaceuticals reported its second quarter 2025 financial results. The slide presentation accompanying this webcast is available on the Investors section of our website. Investors should also refer to the press release we issued earlier today that is available on our website. On the call today are Bruce Cozadd, Chairman and Chief Executive Officer; Renee Gala, President and Chief Operating Officer and recently announced Chief Executive Officer effective August 11; Rob Iannone, Executive Vice President, Global Head of R&D and Chief Medical Officer; and Phil Johnson, Executive Vice President and Chief Financial Officer. On Slide 2, I'd like to remind you that today's webcast includes forward-looking statements, such as those related to our future financial and operating results, growth potential and anticipated development, regulatory and commercial milestones and goals, which involve risks and uncertainties that could cause actual events, performance and results to differ materially from those contained in those forward-looking statements. We encourage you to review the statements contained in today's press release in our slide deck and the risks and uncertainties described under the caption Risk Factors in our annual report on Form 10-K for the fiscal year ended December 31, 2024, and our subsequent filings with the SEC, including our quarterly report on Form 10-Q for the fiscal quarter ended June 30, 2025, which identify certain factors that may cause the company's actual events, performance and results to differ materially from those contained in the forward-looking statements made on today's webcast. We undertake no duty or obligation to update our forward-looking statements. As noted on Slide 3, we will discuss non-GAAP financial measures on this webcast. Descriptions of these non-GAAP financial measures and reconciliations of GAAP to non-GAAP financial measures are included in today's press release and the slide presentation available on the Investors section of our website. I'll now turn the call over to Bruce.

Thanks, Jack. Good afternoon, everyone. Thank you for joining us today to discuss Jazz's second quarter 2025 results. Starting on Slide 5, I'd like to congratulate Renee on her unanimous selection by the Jazz Board of Directors as President and CEO. I'm confident Renee is the right leader to build on Jazz's momentum and serve as a catalyst in driving long-term growth. After working with Renee closely for more than 5 years, I've seen firsthand that she has the right skill set and experience to further drive innovation while nurturing the culture of purpose and patient impact that is at the center of everything we do at Jazz. Since cofounding Jazz in 2003, I've had the extraordinary privilege of leading the company through its growth and significant diversification that has transformed the business into the fully integrated biopharma company is today. I'll continue serving as Chairman of the Board of Directors, providing strategic guidance and look forward to seeing Jazz continue delivering for patients, employees and shareholders. Now turning to Slide 6. Jazz continues to demonstrate considerable progress across commercial, R&D and corporate development. We remain confident in the strength of our diversified portfolio and excited about the potential for future growth as we prepare for the anticipated approval of dordaviprone and approval of Zepzelca in an earlier line of treatment. We're approaching a significant milestone for dordaviprone with the upcoming FDA PDUFA target action date of August 18. We added dordaviprone to our pipeline through the Chimerix acquisition we closed in April, enhancing our presence in rare oncology. Given its patent protection into 2037 with potential to receive patent term extension, and the opportunity for expanded use in the frontline setting, we view dordaviprone as a meaningful and durable revenue opportunity for Jazz. In addition, we have the right…

Thanks, Bruce. I'm thrilled to be stepping into the CEO role to build upon Jazz's incredible success and transformation over the last several years. I'd like to thank the Board for their trust and confidence in me and Bruce for his dedicated leadership of Jazz over the past 2 decades. I believe this company has immense potential, and I look forward to continuing the important efforts underway and working with our team to drive greater value for our patients and shareholders. I know there may be questions about potential changes to Jazz's future direction. Right now, my focus is on ensuring a smooth transition into the CEO role. As we shape our next phase of growth, I plan to listen and gather insights from a broad range of internal and external voices. And as decisions are made, they will be shared broadly. In the meantime, I appreciate your patience and support, and I look forward to engaging on this topic in the future. Now I'll begin on Slide 8 to discuss the progress of our commercial portfolio. Starting with our sleep therapeutic area, total sleep revenue, which includes Xywav and Xyrem net product sales plus royalties from high sodium oxybate authorized generics or AGs was $505 million in the second quarter of 2025. Xywav delivered another strong quarter with net product sales increasing 13% year-over- year to approximately $415 million. As the only low sodium oxybate therapy, the benefits of Xywav in reducing sodium intake and individualized dosing continue to resonate with patients and HCPs. This is reflected by the approximately 625 net patient adds across both narcolepsy and IH exiting the second quarter. We continue to focus on strong execution and enabling as many patients as possible to benefit from low sodium Xywav. Our field teams are generating strong…

Thank you, Renee. Starting on Slide 14. We have an exciting pipeline and are making substantial progress on key programs with additional milestones expected this year. In oncology, we were pleased the FDA granted priority review of our sNDA for Zepzelca, with a PDUFA target action date of October 7 for maintenance therapy in first-line extensive stage small cell lung cancer for patients who have not progressed during induction chemotherapy. The submission was based on the compelling Phase III IMforte data presented at ASCO. We believe these results are practice-changing, and we have submitted the data for potential inclusion in NCCN guidelines. Regarding our Phase III first-line HERIZON-GEA zanidatamab trial, given that we're now in early August, we do not expect to announce top line data in the third quarter. Based on the current event projections, we do continue to expect we will announce top line data late in the fourth quarter of 2025, consistent with our prior disclosure, of the second half of 2025. We are also excited to highlight the recently initiated Phase II trial studying zanidatamab as neoadjuvant and adjuvant therapy in breast cancer. This trial aims to reduce the burden on patients with early breast cancer, increased pathologic complete response rates, improve long-term outcomes and reduce overall toxicity. The randomized open-label trial will assess the past CR rate of neoadjuvant zanidatamab and taxane with or without carboplatin versus a regimen containing a taxane, carboplatin and trastuzumab and pertuzumab. Following surgery, patients with a past CR will continue on zanidatamab and those without a past CR, will receive TDM-1 as adjuvant therapy and will be followed for event-free survival. Turning to our zanidatamab development program on Slide 15. The ongoing clinical trials continue to progress, and we're expanding the program with the new trial in neoadjuvant and…

Thanks, Rob. I'll start on Slide 19 with our top line results. As a reminder, our full financial results are available in our press release, which is available today and in our 10-Q, which will be filed tomorrow morning. In the second quarter of 2025, we generated $1.05 billion in total revenues. This represents an increase of 2% over last year's quarter and was driven by robust Xywav growth of 13%. As Renee mentioned, net patient adds were particularly strong, providing great momentum as we move into the second half of the year. Epidiolexs' growth moderated to 2% this quarter, driven by several factors, including year-over-year inventory dynamics in the U.S., as Renee mentioned earlier. Despite inventory dynamics, we continue to be pleased with the demand we're seeing for Epidiolex. In total, our oncology products decreased 1% compared to the second quarter of 2024 as lower sales of Rylaze and Zepzelca were largely offset by higher sales of Ziihera, Defitelio and Vyxeos. Looking forward, we remain optimistic and confident in the future of our oncology franchise and are ready to successfully execute on the rolling launch of Ziihera for BTC in Europe and the potential near-term launches of dordaviprone in our current H3 K27M- mutant diffuse glioma and of Zepzelca in the first-line maintenance setting for small cell lung cancer. In addition, we look forward to the upcoming Phase III first-line GEA readout for zanidatamab. Adjusted net loss for the second quarter of this year was $505 million. This loss was entirely driven by the $905 million nontax deductible acquired IPR&D charge from the Chimerix acquisition. We continue to generate significant cash, recording $519 million of operating cash flow in the first half of the year. And even after the acquisition of Chimerix and payments to settle certain of the…

I'll conclude our prepared remarks on Slide 23. We remain well positioned to deliver shareholder value as we head into the second half of 2025. We continue to focus on optimizing our commercial execution, advancing key development programs and maintaining our commitment to patients who depend on our medicines. I'm pleased with the robust net patient adds exiting the quarter for Xywav, the only low sodium oxybate and continue to anticipate Epidiolex will reach blockbuster status this year. As our oncology portfolio overcomes near-term headwinds, we expect to return to growth driven by new opportunities. We look forward to our 2 upcoming PDUFAs, 1 for dordaviprone this month, and 1 for Zepzelca in October as well as the top line readout of the Phase III HERIZON- GEA clinical trial expected late in the fourth quarter of 2025. Again, I'd like to congratulate Renee and thank our talented employees for their dedication and commitment to innovating to transform the lives of patients and their families. That concludes our prepared remarks. I'd now like to turn the call over to the operator to open the line for Q&A.

[Operator Instructions] Our first question comes from Marc Goodman at Leerink. Our next question comes from Jason Gerberry at Bank of America.

Congrats, Renee and Bruce, it's been awesome working with you. So my question is what's driving the strength of Xywav and IH, specifically the patient adds look like they're sustainable and going up. And just kind of curious if I can get your perspective on the sustainability of that rate of patient adds into next year.

Renee, do you want to jump in on that? While we're waiting for Renee to figure out how to get off mute unless somebody else can hear. I'll just say, Jason, it's been a pleasure working with everyone over the past many years that Jazz has been a public company since 2007. And for a couple of you out there on the buy side and the sell side, I'd probably go back 30 years. So it's been a real pleasure getting to know you all and I will be watching Jazz's forward progress as all of you will, under Renee's leadership. So with that, Renee, over to you.

Yes. Can you hear me now?

Yes, we can.

Okay. Great. Sorry, I'm not sure what happened there. So thanks, Jason. We're really pleased with the growth that we saw in the quarter with Xywav, both in narcolepsy and in idiopathic hypersomnia. In terms of IH, we do see that as being an area where we see the most opportunity for growth as Xywav is the only FDA-approved therapy. So in terms of what's driving the growth, we have seen some really strong execution across our field teams and our investments. Our consumer targeted digital and media campaigns are performing really well. We have invested quite a bit in building disease awareness and patient education. Because this, of course, is an area where in the past, if you haven't had an approved therapy, there's not necessarily a large incentive to go through the process of getting diagnosed. And then I would say also our field nurse educator program is particularly helpful with IH patients. When you think about starting oxybate therapy, there is greater persistence once you have titrated up to an efficacious dose. The field nurse educators assist with this. And in particular, with this community of IH being less familiar with oxybate therapy, as compared to narcolepsy, that's been another really helpful service that we've been providing to patients and is helping our persistence and overall growth.

Our next question comes from Jess Fye at JPMorgan.

Congrats to Renee on the new role and to Bruce on retirement. I wanted to ask about zani for the Phase III trial coming up. If I recall, Jazz's top line updates have historically been more qualitative in nature with numbers to follow later. Is that how we should think about the zani top line? Or could there be potential for any numbers this time around? And if the update is more qualitative, can we expect to hear comments on both zani arms?

So Jess, I'll jump in first and then see if Rob wants to add anything. Typically, we've tried to give important top line results in terms of have we hit or not a primary endpoint or certain prespecified secondary endpoints if we think they're germane and important while preserving our ability to publish and present at major conferences by not sharing all the information. We often tried to give qualitative commentary that helps people understand the clinical meaningfulness of results in other ways. So we're not trying to leave people completely in the dark. But it's rare that we go all the way to full statistics. We're also, of course, often unblinding results and sharing them fairly quickly at the top line, while continued analysis goes on at a very detailed level as we prepare for regulatory filings and otherwise. Rob, anything you want to add?

I think that was great, Bruce. And I would just say our recent experience with IMforte is probably a good example where we not only set stat sig, but we commented on both endpoints, PFS and OS and gave some color around it being clinically meaningful and practice changing.

Our next question comes from David Amsellem at Piper Sandler.

So I had a question on Zepzelca. I know you've talked about the competitive headwinds here. Your competitor on its call did cite growing traction of tarlatamab in the community setting. And so I'm just wondering out loud, with that in mind, do you see continued headwinds for Zepzelca in second line? And at what point do you start to see perhaps stabilization with the label expansion? And when do you think we'll have better visibility into a return to growth for Zepzelca?

Yes. Renee, do you want to take that?

Sure, I'm happy to jump in. Can you hear me?

Yes.

Okay. Perfect. So thanks for the question, David. And certainly, we have commented on a couple of different dynamics impacting our sales of Zepzelca, 1 being the increased competition in the second line tarlatamab. Now these impacts were in line with our expectations. However, it is having an impact on our overall positioning in the second line. And then, of course, we've also said that we've seen increased adoption of IO in the treatment of first-line limited-stage, small cell lung cancer. This is the impact of the adriatic regimen, and that's delaying progression of some of those first-line limited-stage patients from the first line into the second line. And we can see this trend in claims data. Importantly, we're really looking forward to the potential approval in first-line maintenance for extensive stage based on the IMforte study data that Rob was just mentioning. So we have our PDUFA date on October 7. We have already submitted for potential inclusion in the NCCN treatment guidelines. We do expect this data to be practice-changing. And we do expect, as we look at that first-line population to have a larger group of patients, and we have talked about the duration of therapy also being longer there. So that's really what we're focused on.

Our next question comes from Andrea Newkirk at Goldman Sachs.

Maybe as a follow-up to a prior 1 for Rob, when you think about the sustainability of Xywav's growth profile on the forward, is there anything you're looking to understand from the upcoming orexin data presentations at World Sleep to better inform how you think orexin agonist and oxybates will coexist in the rare hypersomnia space?

Thanks for the question. I mean certainly, we've only seen limited data. And so I am eager to see as much data as possible, not only in terms of daytime efficacy measurements but the overall safety and tolerability profile and very, very interested in understanding impact on nighttime sleep. As we know, alerting agents often can disrupt nighttime sleep, which is really the root cause of narcolepsy. Narcolepsy patients have substantially disrupted nighttime sleep. For example, on average, about 80 awakenings a night with not as much deep sleep, not as much deep sleep or total sleep time. So the impact on nighttime sleep where Xywav has its main impact and results in benefit during the day is going to be important. So we continue to think about these 2 mechanisms as potentially being complementary.

Our next question comes from Akash Tewari at Jefferies.

Rob, you mentioned that for the top line press release for HERIZON-GEA, you could give commentary on whether the PFS would be clinically meaningful and practice changing. Can you kind of prospectively identify what that would look like for zani in that indication? And then maybe, Renee, I had asked Bruce this maybe a year ago, when you think about core and noncore parts of Jazz, and I think Bruce had alluded, there could be parts of Jazz that are noncore to the business going forward. You guys have such an esoteric mix of products. How would you define what is core and noncore within the Jazz portfolio?

Yes. Thanks for the question. I would say it's always hard to give a specific number to say, if we observe this, we think it will be practice changing. But this field certainly has evolved over the last 10 to 20 years, and you can look at examples of how clinical trials have resulted in change in practice, whether that be from the ToGA trial to establish Herceptin through the JACOB trial and then more recently KEYNOTE-811, where KEYNOTE-811 had about a 2-month median PFS difference and about a 4-month overall survival difference. So I think the benchmarks are out there. We're very encouraged by the 2 frontline Phase II trials that have been conducted, 1 recently published at ASCO, zani plus chemo with a median overall survival of 36.5 months, very encouraging, but strong response rate, duration of response and PFS as well. And those data were very comparable to the other trial where tislelizumab was added and you saw in some respects, incrementally better results as well.

Yes. And I'm happy to jump in on the second question, Akash. So yes, I appreciate that you are thinking about core and noncore parts of Jazz. And I do think, at times, what people miss is at the core of our business, the vast majority of our products are essentially rare disease or orphan disease products. And so while on the surface, they may not always look like they fit together but the underlying capabilities that are required to identify patients to be able to partner with, interact with patient advocacy groups to understand patient needs to be able to target and engage with physicians in some of the field execution capabilities, those are actually quite similar across a number of our products. Now I would also say, when you look at Jazz over time, there have been a number of businesses, products that we have decided to divest because they did not necessarily fit into the core business that we were looking to, to drive growth and where we felt we could invest to continue to bring forward. I would say Sunosi is a good example of that. Even though it was a product within sleep, it no longer fit the type of business model that we were focusing on going forward. So as I'm stepping into the new role, I will be looking at where is the best place for us to be investing. As I mentioned, I do intend to spend time listening, talking to both internal and external parties to better inform the direction that we go forward. But we are in an excellent position today with roughly $4 billion of top line revenue, healthy cash flows and multiple products to be able to invest in, both on the commercial and pipeline front as well as continued appetite for corporate and business development.

Our next question comes from David Hoang at Deutsche Bank.

Congrats on the quarter. So maybe one on Epidiolex. I want to ask about what underlies the confidence there that, that product will reach blockbuster status this year? And are there any potential headwinds that may be related to seasonality that could impede those growth expectations? And then on the oxybate franchise, could you just refresh us about potential entry of multi-source oxybate generics near term and how that might impact the business?

Sure. I'm happy to jump in on both of those. So with respect to Epidiolex, this is a product that we do remain confident in, in terms of reaching blockbuster status this year and ongoing growth. It's also a product that does tend to see seasonality that impacts inventory and as a result, can impact our growth when you're comparing quarter-over-quarter. And the second quarter is an excellent example of that. We saw strong underlying demand growth -- but we also saw a typical inventory build last year. Typically, we see inventory build in the second half. It burns off in the first quarter, sometimes into the second quarter. But last year, we saw that inventory build start in the second quarter, which, therefore, as a result, not seeing that same dynamic in the second quarter of this year, means it negatively impacted our growth rate. We do expect to see a gradual build of inventory in the second half of this year. And the overall growth when you look between 2024 and 2025, doesn't actually need to be very high in order to reach blockbuster status. But given the strong underlying demand that we see, we feel highly confident that we'll achieve that at a minimum. With respect to your second question...

Yes, timing of multisource generics.

Yes. Sorry, Thank you. With respect to the timing of multisource generics, they have the ability to enter on December 31 of this year. Of course, Hikma has the ability with notification to us to enter at any time. They have had that ability over the last roughly 1.5 years as well as the ability to extend the -- continue in the AG agreement through the end of 2027. So if a generic enters onto the market at the end of this year, they will need to have their own REMS to be able to support their product. And we continue, as a result, to really focus on the differentiation of Xywav as the only low sodium oxybate on the market as the #1 treatment within narcolepsy, the #1 branded treatment as well as the only product available and approved for IH. So I think, Phil, you wanted to jump in and add something as well?

Yes. Epidiolex real quick. Just in terms of the growth that's required, as Renee mentioned, we finished last year with $972 million in global revenue, effectively need less than 3% growth to get past $1 billion. We did grow 5% in the first half of the year this year. And as you'll see in the Q, where we have some disclosures on volume growth for certain products, volume growth continued to be robust at 6%. So some of these inventory things will fluctuate from period to period. As Renee mentioned, we're really pleased with the underlying demand that we're seeing for the product.

Our next question comes from Ami Fadia at Needham.

Congratulations to Renee on your new role and to Bruce on your retirement. I'm sure you'll be missed. My question is a follow-up on the zani GEA trial. Given that you've increased the enrollment of the study somewhere in early 2024, do you think you'll have data that will be mature enough for you to have a look on OS? Or would you need to wait for the next interim look there? And what is the bar for showing a trend towards OS benefit? Is it simply a hazard ratio under 1 or something more specific? And then just with regards to the disclosure that we can expect in the fourth quarter with regards to arm C, how much of an improvement would you need to see versus arm A or B to indicate that adding tislelizumab is sort of incremental for PD-L1 patients?

Thanks, Ami, for the questions. So as a reminder, we have 3 planned overall survival analyses. The first is time for when we do the 1 and final PFS analysis. And so certainly, it doesn't have the full maturity that we'll have even at the second, but certainly the final. However, the additional time, as you point out, in getting to the PFS endpoint certainly improves the power in OS relative to what we might have had a year ago. So it improves our chances, so to speak. And your next question was how much of a trend is needed on OS? I think it depends ultimately on the totality of the data. We certainly don't get into that kind of specific discussions with health authorities, et cetera. But depending on the magnitude of effect of PFS, I think it will all be considered together. There's a fair amount of precedents in this space in terms of approvals. Of course, the ToGA regimen Herceptin showed an overall survival benefit. And KEYTRUDA had an initial approval, accelerated approval on response rate and then full approval on PFS before having mature OS data. So I think there is a certain amount of precedent in this space to go by. And then lastly, you asked the question of what is the incremental benefit that you need to observe in arm C versus B in order for that to be approvable. And again, I think it's a totality of the data question. Certainly, it needs to be contributing meaningfully and the overall benefit risk needs to be favorable.

[Operator Instructions] Our next question comes from Joseph Thome at TD Cowen.

Congrats to both Renee and Bruce. Maybe when we talk about the frontline GEA data, this has been pushed a little bit. And even though it's in the current guidance, it sounds like it's going to be later in the fourth quarter. I guess, can you talk a little bit about your confidence that the data will come this year? And also maybe your confidence that the control arm A is performing similarly to prior studies? And then maybe just a little bit of a tack on what would that subsequent OS analysis be?

Yes. So I would just say we remain blinded overall to the data. But as we get further along in the study and more mature, the assessments around when maturity will come, have greater precision. So we have greater confidence in our projections around that. And that has led to a refinement there. Could you clarify again the last part of the question that you asked?

Yes. I guess just the confidence that the control arm is performing similarly to prior studies. And then you indicated that there are several OS analyses and the first 1 comes with a mature PFS. I guess when is the next 1 after the mature PFS? When would you expect that to be available?

Sure. So again, this is an area that is, I would say, a disease setting that's been very, very well studied. And if you look at ToGA, JACOB and then KEYNOTE-811, the control arm has performed in a fairly narrow band. And I think it's reasonable to expect in the modern era that the control arm would be similar to the KEYNOTE-811 results. We're blinded to the data, so we can't say for sure how the control arm is performing. But I think that Herceptin and chemotherapy has performed pretty consistently across studies. And so that makes it easier for planning purposes. We haven't given details on exactly how much maturity we would have, for example, on the second interim analysis. But what we have said in the past is when we increased the sample size from approximately 700 to approximately 900, it allowed us to sort of roughly maintain what had been the timing for, and what had been planned for a final OS analysis while adding a later analysis to be the final and to be better powered.

Our next question comes from Joon Lee at Truist Securities.

You have a very strong momentum in the narcolepsy franchise, but Takeda is planning to submit an NDA for their orexin agonist for NT1 and Axsome is also planning to submit an NDA for their NT1 narcolepsy drug in 4Q. So how much impact, if any, do you think that Takeda and Axsome drug could have on your current momentum in the narcolepsy franchise, given the potential differences in the VA scheduling? And where are you with your orexin agonist 441?

Renee, do you want to take the first part on potential impact of product entry? And then Rob, any update on 441?

Sure. Happy to do that. So I would say, I'll let Rob comment on some of the mechanisms, but we continue to believe in general that oxybates will be complementary to orexin. And then when we lay out the differentiation of Xywav with both low sodium being the only low sodium oxybate on the market and flexible dosing, we see that HCPs and patients alike continue to choose the low sodium based on the underlying cardiovascular conditions that often exist and the propensity to develop cardiovascular conditions on high sodium oxybates. And I would say also, when you think about other mechanisms, be it wake-promoting agents or stimulants, we simply have not seen a meaningful impact with any of those launches on our Xywav momentum. So again, we would think of these as being largely complementary. When you think about the studies that we ran for Xywav, we saw a large number of patients coming in on a background of wake-promoting agents and still improved meaningfully with Xywav. Rob?

Yes. I mean I'd love to add that we have very, very extensive and robust data, not only with Xywav, but in the oxybate field in general, and many, many years of patient experience showing that when administered at night, and of course, it's washed out by the time patients wake up in the morning. There's a very significant and clinically meaningful impact on nighttime sleep, improving key parameters like total sleep time, reducing awakenings after sleep onset dramatically, improving deep sleep, consolidating REM sleep. And that improvement in what's the -- essentially the underlying root cause of the daytime symptoms translates then into more wakefulness and less cataplexy during the day. Certainly, what we've seen of orexin is that they are potent daytime alerting agents. What we haven't seen is orexins improving meaningfully nighttime sleep. The little data that are in the literature shows some consolidation of REM sleep, but really no impact on total sleep or deep sleep. And we haven't seen a lot of data around that first part of the night where residual exposure to orexins might actually be disrupting sleep. And that's partly why we think that these mechanisms are likely to be complementary. I would mention that at APSS, we recently published more PSG data, both in narcolepsy and IH, again, establishing the value of Xywav for improving nighttime sleep. And then with regard to our own program, as we mentioned, we are already dosing in a small cohort of NT1 patients to evaluate whether JZP-441 could progress beyond this stage, depending on the therapeutic index that's observed, and we continue to pursue a backup program that's in the preclinical space.

Our next question comes from Ash Verma at UBS.

Congrats on your retirement, Bruce. I wanted to ask a more bigger picture question on your journey. So I know you've made pretty massive strides in terms of diversifying the business. But in terms of the stock, there was a pretty significant outperformance from inception, but it's been range bound for the last, let's say, 10-plus years. So from your perspective, what do you think drove that disconnect? And then, Renee, any learnings you can take from this experience and how you think you can maximize the shareholder return as a CEO?

Yes. Ash, thanks for the question. I would say, the diversification of our business has been important to have multiple growth drivers, not only the strong continued performance of our sleep business, but the growth in Epidiolex now with its clear long-term runway as well as exciting developments in the oncology portfolio as we've continued to add new drugs and expand the opportunity for drugs we do have with a lot of excitement, in particular, around zanidatamab. A place we've begun to be more active again is corporate development. We've always said that's part of our strategy. We had a bit of a pause after doing the larger GW transaction as we delevered, but that's a clear priority for us as you saw with the Chimerix transaction earlier this year, which hopefully leads to near- term launch and a really nice return for us. So we've been trying to make that strategic shift over a number of years. It's been quite dramatic going from 75% of our revenues being dependent on 1 product, which is now a very, very small percentage of our revenues to having these multiple drivers. So I think we've set the company up well as a platform to continue to grow, and I'll let Renee talk about where we go from here.

Yes. Thanks, Bruce. And I think at this point in time, it might be a bit premature, Ash, to go into a lot of detail. I'm thrilled to be stepping in where the company is today with respect to the strength of the balance sheet, the revenues we're generating, we have multiple approvals ahead, a very meaningful pipeline readout coming in GEA and a workforce that is highly engaged and passionate about what we do. So I do believe there is really meaningful value to unlock here, and I look forward to working with the team to be able to accomplish that. So stay tuned.

Next question comes from Sean Laaman at Morgan Stanley.

This is Mike Riad on for Sean. I'd also like to extend our congratulations to both Bruce and to Renee. For JZP441, is there a likelihood to get the Phase Ib results this year in NT1? Or is that more of a first half '26 event?

We haven't given specific timing on that. All we've said is that it's a relatively small study. We think in 10 patients or fewer, we can get a read on the therapeutic index. And it is an open-label trial. So patients are enrolling. And as soon as we have meaningful information, we'll provide an update.

Our next question comes from Mohit Bansal at Wells Fargo.

Congrats, Bruce, on the retirement and Renee, very well-deserved promotion. Looking forward to continue working with you. So my question is regarding tariffs and MFN. And I think last quarter, you talked about Ireland being important for Xywav, what about other products? Do you see any impact on products like Epidiolex and ALL as well? And given your portfolio of rare disease drugs, do you think the MFN recent chatter around MFN being impacting the Medicaid pricing could have an impact on these drugs as well?

Yes, Mohit, thanks for the questions. So maybe starting with tariffs. As we had talked on prior call, we do have the opportunity to produce our oxybate products here in the U.S. with a supplier that has more than ample capacity that's available to us to serve all of our U.S. needs. And we also have a U.S. CMO that does the drug product for Rylaze or for -- yes, Rylaze as well. So I would say in terms of the exposure we've got to tariffs, similar to what we said in the past with steps we've taken to mitigate that risk, there really is no exposure to either the existing or some of the ones that are pretended to be coming here in the near future to our 2025 results. And we have a decent amount of coverage for nearly all of our products in terms of U.S. inventory already here locally in the States to cover a decent portion of our 2026 needs as well. Beyond that, we'll continue to look for ways to go ahead and mitigate that exposure, which could include working with additional third parties here in the U.S. for other manufacturing. So we'll continue to keep you updated there. On MFN, it really is, obviously, the sort of topic of the last few days here. A lot still is unclear about scope, time line operational mechanisms of how the administration may pursue MFN drug pricing, what may happen legally in terms of challenges to proposals that could be coming. So I'd say at this point, it is premature to speculate on what's going to happen specifically and therefore, put some kind of quantification of our exposure. I would say we do have exposure because we do have U.S. government business and ex U.S. prices are typically lower than U.S. prices, and some of the products that would have a larger exposure for us based on their proportion of government business would include, for example, Rylaze and Epidiolex. But again, much more to come here, I'm sure, in the coming weeks and months, and we'll keep you appraised as we have something more specific to be able to say based on concrete proposals.

Our next question comes from Gary Nachman at Raymond James.

Bruce, best of luck to you, and my congrats as well, Renee. So on dordaviprone, what's your confidence level in the accelerated approval at the PDUFA on August 18? Have your conversations been going with FDA, if that's all been on track? And I know you'll have a webcast after, but high level, how are you thinking about that opportunity and how quickly it could ramp up in that subset of glioma patients? And can you just roll this into the current oncology sales infrastructure?

Yes. Maybe in the interest of time, since we're getting short, I'll just say, Gary, we've been in conversations with FDA, and we know what the PDUFA target action date is, and we hope to have an FDA decision very soon. Renee, maybe I'll let you comment a little bit on the opportunity. I'll just say we're really excited about the opportunity to bring this therapy to patients and think there's a real nice opportunity to make a difference for a lot of patients.

Yes, absolutely. Happy to make a few comments. I mean, first, we are incredibly excited about this potential approval and making this medicine available. This has been a I would say, true labor of love for our colleagues at Chimerix, and we look forward to bringing it to market. We do believe the product will be predominantly administrated in -- administered in academic settings of excellence. So we do think largely a more concentrated call point. And as a result, we are looking at a relatively small but dedicated group to be able to augment our internal footprint, ensure we have sufficient focus on the launch, but also do so in a highly concentrated way. And I would say we're also excited about this patent portfolio that goes out well into the late 2030s, 2037 with the potential to receive patent term extension. So we also believe this is a durable, long-lived product. More to come, though, with respect to our launch meeting.

Our last question comes from Marc Goodman at Leerink.

This is Basma on for Marc. Could you please provide quick color on the launch on the BTC performance in the second half, the Ziihera in BTC in the second half of the year? And also, we just have a quick question on Epidiolex. Can you remind us if you did collect cognitive data in the different DEEs such as LGS and GS and Dravet? That's it for us.

I think in light of the limited remaining time, we'll just answer the first question, which, Renee, maybe will come to you on the BTC launch.

So I would say, keep in mind that BTC represents a very small patient population. And as we've said, while this is very important for us to make this medicine available for patients, we do expect the revenue contribution to be modest. We don't provide guidance by product. So I'm not going to give specific expectations for the second half. But I would say what we're hearing from HCPs is they're really pleased to have the product available. They're having a positive experience with the drug. And for us, we're really looking forward to seeing the GEA data late in the fourth quarter.

This concludes the question-and-answer session. I would now like to turn it back to Bruce Cozadd for closing remarks.

All right. Thank you, operator. And I'd like to close today's call by recognizing our Jazz colleagues for their efforts and thank our partners and shareholders for their continued confidence and support. And as I said earlier in the call, it's been a pleasure working with many of you for a few years. A lot of years, a decade, 2 decades or 3 decades, depending on who I'm talking to, and you're in very good hands with the continuing Jazz team. So good afternoon, everyone.

Thank you for your participation in today's conference. This does conclude the program. You may now disconnect.
