IONS - NASDAQ

Good morning, and welcome to the Ionis Second Quarter 2024 Financial Results Conference Call. As a reminder, this call is being recorded. At this time, I would like to turn the call over to Wade Walke, Senior Vice President of Investor Relations, to lead off the call. Please begin.

Thank you, Danielle. Before we begin, I encourage everyone to go to the Investors section of the analyst website to view the press release and related financial tables that we will be discussing today, including a reconciliation of GAAP to non-GAAP financials. We believe non-GAAP financial results better represent the economics of our business and how we manage our business. We've also posted slides on our website that accompany today's call. With me on this morning's call are Brett Monia, our Chief Executive Officer; Richard Geary, Chief Development Officer; Kyle Jenne, Chief Global Project Strategy Officer; and Beth Hougen, our Chief Financial Officer; Eric Swayze, Executive Vice President of Research; Eugene Schneider, Chief Clinical Development Officer; and Jonathan Birchall, Chief Commercial Officer, will also join us for the Q&A portion of our call. I'd like to draw your attention to Slide 3 in our presentation, which contains our forward-looking language statement. During this call, we will be making forward-looking language statements that are based on our current expectations and beliefs. These statements are subject to certain risks and uncertainties, and our actual results may differ materially. I encourage you to consult the risk factors contained in our SEC filings for additional detail. And with that, I'll turn the call over to Brett.

Thanks, Wade. Good morning, everyone, and thanks for joining us on today's call. We've achieved a great deal during the first half of this year, delivering many significant milestones as we continue to execute on our vision to bring better features to people with serious diseases. Today, Ionis discovered and developed medicines reaching more and more people, bolstered by two recent launches, WAINUA for people with hereditary ATTR polyneuropathy in the U.S., and QALSODY, the first approved treatment for a genetic cause of ALS currently available in the U.S. and now and available in Europe. And with the progress we're making across our pipeline, our medicines are well positioned to continue reaching more and more patients for years to come. The U.S. launch of our first Ionis co-branded medicine WAINUA is progressing well with Astra

Thank you, Brett. We are pleased that our pipeline delivered many important achievements to date this year. With WAINUA reaching more and more people with hereditary ATTR polyneuropathy. I am proud of all that Ionis team has accomplished to discover and develop this important new medicine and bring it to patients in need. Recent ATTR cardiomyopathy data further reinforces our confidence in the potential of WAINUA to improve cardiovascular outcomes in this estimated worldwide patient population of approximately 300,000 to 500,000. With over 1,400 patients enrolled, our ongoing CARDIO-TTRansform study is the largest and most comprehensive study ever conducted in ATTR cardiomyopathy. And as a result, we expect the data we generate will enable physicians and payers to make informed treatment decisions in this dynamic treatment landscape. In addition, as part of our Phase 3 program, we're conducting advanced cardiac imaging sub-studies, including an MRI sub-study and a [indiscernible] sub-study, which will generate valuable data about the potential benefits of WAINUA in cardiomyopathy patients. We were delighted that our recent Olezarsen NDA submission was accepted by the FDA for priority review, highlighting the potential of this medicine to make a profound difference in the lives of patients. Our submission was based on the positive Phase 3 results in FCS that we presented and published earlier this year. In the Phase 3 BALANCE study in patients with FCS, Olezarsen showed substantial and durable triglyceride reductions. And importantly, for patients, physicians and payers alike, Olezarsen demonstrated substantial and clinically meaningful reductions in acute pancreatitis attacks, a remarkable 84% reduction in hospitalizations and a favorable safety and tolerability profile. We look forward to our upcoming December PDUFA date and assuming approval, bringing Olezarsen to people with FCS who currently have no approved treatments in the U.S. We are also developing Olezarsen for the much larger severe triglyceride patient population, and we recently completed enrollment in our extensive Phase 3 program for sHTG with more than 2,500 patients enrolled across three studies. This puts us on track for data in the second half of next year, maintaining our multiyear first-mover advantage for this wholly owned blockbuster opportunity. Following closely behind Olezarsen is Donidalorsen for the prophylactic treatment of hereditary angioedema. We recently presented and published in the New England Journal of Medicine positive Phase 3 data from OASIS-HAE, our placebo-controlled trial. Additionally, we also presented positive data from OASISplus. Our trial that includes an open-label cohort for patients rolling over from the Phase 3 study and a separate cohort that we refer to as the SWITCH study. Donidalorsen treatment significantly reduced HAE attacks. The reduction in HAE attacks translated into significant and clinically meaningful improvements in quality of life across multiple validated measures and high levels of disease control in a vast majority of patients. And with longer-term treatment, patients improve further on all these measures. Additionally, as of our most recent data cutoff in February, 98% of patients remain in the study. These positive data were further bolstered by the encouraging SWITCH results. The SWITCH study through week 17, patients showed a substantial reduction in their HAE attack rate with Donidalorsen treatment compared to baseline on their previous treatment. Donidalorsen treatment also resulted in improved quality of life measures and increased disease control. Importantly, more than 80% of patients surveyed reported a preference for Donidalorsen over their prior prophylactic treatment. And nearly 90% of SWITCH study patients remain in study as of the data cutoff in February. In addition to strong clinical results, Donidalorsen offers the potential for simple, monthly or every two-month self-administration via an auto-injector. Based on these data, we believe Donidalorsen could become a preferred prophylactic treatment for people with HAE. Our NDA, which we plan to submit soon will include data from OASIS-HAE, OASISplus, OLE study SWITCH and our Phase 2 study. Outside the U.S., Otsuka is preparing to submit for marketing approval in Europe later this year. And with the recent expansion of our license agreement, Otsuka also plans to bring Donidalorsen to patients in the Asia-Pacific region. The rest of our rich Phase 3 pipeline is also advancing, positioning us to continue delivering a steady cadence of potentially transformational medicines to patients. We recently completed enrollment in the pivotal arm of our zilganersen study for Alexander Disease keeping us on track for a Phase 3 readout next year. From GSK recently completed enrollment in the Phase 3 program for Bepirovirsen for chronic hepatitis B, which keeps the program on track for data in 2026. Coming right behind these programs, we have our next wave of medicines including a number of medicines to treat both rare and broad neurological diseases, five of which are wholly owned. And we expect our wholly owned pipeline to expand later this year in two more medicines from our neuro disease franchise enter clinical development. ION582, our medicine for Angelman Syndrome has transformational potential for the tens of thousands of people living with this serious rare disorder, who are in need of disease-modifying treatments. For this reason, ION582 is poised to become the cornerstone of our wholly-owned neurology pipeline. We're encouraged, I recently presented positive early results from the HALOS study of ION582 and people with Angelman syndrome. In this study, we demonstrated evidence of consistent and meaningful improvement on all key functional areas across multiple assessments. This includes 97% of participants showing clinically meaningful improvement in overall Angelman syndrome symptoms on the SAS CGI assessment. Improvements in measures of communication, cognition and motor function exceeded natural history on the Bayley-4, Vineland-3 and ORCA assessment. Additionally, we observed consistent improvements across ages and genotype. And we saw favorable safety and tolerability at all dose levels, including no discontinuations or adverse events that were considered related to study drug. Based on these positive data, we plan to advance ION582 into a well-controlled Phase 3 study in the first half of next year. Alongside the positive Phase 1/2 data for Angelman Syndrome, several recent events have also occurred in our mid-stage pipeline. We were pleased to present positive Phase 2 data at EASL for ION224, our medicine targeting DGAT2 for the treatment of Metabolic Dysfunction-Associated Steatohepatitis or MASH. Additionally, based on the encouraging Phase 1b data from IONIS-MAPTRx also known as BIIB080 that were presented late last year, Biogen recently announced that they amended the ongoing Phase 2 study with the goal to accelerate a potential proof-of-concept to outcome. As a result, this change, they are now projecting data in 2026. Also, we and our partners recently discontinued development for ION541 targeting ataxin-2 for ALS and IONIS-FB-LRx for geographic atrophy. Both programs showed good target engagement and favorable safety but did not meet their primary efficacy end points. Importantly, Roche continues to advance the IONIS-FB-LRx IgA Nephropathy Phase 3 study that they initiated last year based on positive Phase 2 data. Looking ahead, we have several important milestones still to come this year. These include presenting new Phase 2 open-label extension data for Donidalorsen and data from the DEVOTE study, which is evaluating a higher dose of SPINRA

Thank you, Richard. We are pleased with the initial results of the WAINUA launch with Astra

Thank you, Kyle. Our results in the second quarter and first half of this year reflect the excellent progress we've made toward our goal to bring a steady cadence of medicine to the market. We continue to generate meaningful revenue while investing our capital to independently launch several new medicines over the next few years that have a combined multibillion dollar peak sales potential. We are also investing in advancing our next wave of wholly owned medicines, which continued to make great progress in the first half of this year. In addition to our recent pipeline achievements, we delivered strong financial results, keeping us on track to achieve our financial guidance. We earned revenues of $225 million and $345 million for the second quarter and first half of this year, respectively. SPINRA

Thank you, Beth. As just summarized, we have made great progress in the first half of this year. And in the second quarter alone, we've achieved a great deal with many important successes, which include a continued strong start for the WAINUA launch for hereditary ATTR polyneuropathy in the United States, approval in Canada and submissions under review in many additional territories. Positive FCS data for Olezarsen, which we present at ACC, which were the basis for our NDA submission, which was recently accepted by the FDA with priority review. Positive HAE data for Donidalorsen presented at [indiscernible], that will be the basis of our upcoming regulatory submissions. And we completed an enrollment for the Phase 3 Olezarsen sHTG program this past quarter, keeping us on track for data next year. We also presented positive data from the HALOS Phase 1/2 study in people with Angelman syndrome, and we are well along in preparing for our end of Phase 2 meeting with the FDA scheduled for this Fall, with plans to advance this important medicine in the Phase 3 development next year. And we delivered solid second quarter and first half financial results, keeping us on track to achieve our 2024 financial guidance. Based on the strong progress we've made across our business this year, we are well positioned to continue building on our positive momentum as we execute towards achieving all of our strategic priorities. We've arrived where we are today by being focused on a clear vision and a clear set of strategic objectives which include building and advancing our pipeline and delivering medicines that we can see, discover and develop directly to patients. Our pipeline is delivering. We achieved multiple marketing approvals and positive key data readouts over the past year, and we are poised to build on the strong momentum in the near term. We prioritized building our wholly owned pipeline and are now advancing several of these medicines towards the market. In parallel, our partner programs are progressing on track with important Phase 3 readouts next year and beyond. We are also focused on extending our leadership position in type therapeutics by expanding and diversifying our technology, further optimizing our capabilities for existing therapeutic areas and opening up new areas for drug discovery. All of this sets us up to continue bringing a steady cadence of new medicine to patients for years to come. We're looking forward to sharing our progress as we build on our recent achievements and accomplish our strategic objectives. And with that, I'll now open the call up for questions. Before moving into the Q&A portion of our meeting, I just ask that our analysts, please limit yourselves to a single question as we have quite a long queue. We'd like to get as many people into the queue and ask their questions as much as possible. So with that, Danielle, we'll open it up for questions.

Thank you. We will now begin the question-and-answer session. [Operator Instructions] The first question comes from Akash Tewari from Jefferies. Please go ahead.

Hey, this is Amy on for Akash. Thanks so much for taking our question. So one on ATTR CM. There's been some debate on if you need a certain level of TTR to have a cardioprotective effect. Have you seen anything in your own data around this theory? And do you expect any differences with the silence your approach using in all-cause mortality versus the mortality composite primary endpoint? Finally, do you have the flexibility to change your primary endpoint if needed? Thanks so much.

Thank you, Amy. So we have seen -- we don't believe that there's any evidence of a threshold effect, for TTR lowering to achieve benefit in either polyneuropathy or in cardiomyopathy endpoints. We're very pleased with the magnitude of TTR reductions that we have seen in our -- in all of our studies for WAINUA for polyneuropathy, very pleased with the level of magnitude of TTR lowering that we're getting. But I don't believe that there's any believable evidence out there that suggests a specific threshold effect for TTR lowering to produce benefit in polyneuropathy or in cardiomyopathy. We believe -- our primary endpoint is in cardiovascular mortality and hospitalization. And that's what we're laser-focused on. We also have a secondary endpoints, specifically CV mortality as well as closed mortality. We think both are very important. Next study or next question.

The next question comes from Myles Minter from William Blair. Please go ahead.

Hi, just on the timing of the CARDIO-TTRansform readout, I mean, is it fair to say that your -- at least waiting for data at ESC in London that might have read through your trial? And if that is the case, what exactly would you be looking for out of that data set to stick with the decision that you're going to read that out early or just wait until the full 140 weeks up in that study?

Thanks, Myles. So we're very pleased with the way the CARDIO-TTRansform study is advancing. We are particularly pleased with the blinded events that were continuing to evaluate both CV hospitalizations as well as mortality. It's going very well right on track. As the first silencer to read out in this indication, we're very much looking forward to any and all additional data that we can see, which we think will be a very nice read-through to our CARDIO-TTRansform study. As you know, we have the largest by far study ever conducted in this patient population. And we think that anything we see from other molecules in the silencer trails are going to be very, very good read-throughs to what we expect to see in our study. So we're just looking forward to any and all data that comes from future presentations on the silencer class. Next question please.

Thank you.

The next question comes from Mani Foroohar from Leerink Partners. Please go ahead.

Hey guys, you have Ryan on for Mani. Thanks for taking our question. Can you just talk a little bit about any early insights from the WAINUA launch? And how you see that informing a potential on strategy in cardiomyopathy? And kind of alongside that, maybe what pre-commercialization activities you guys are undertaking in cardiomyopathy? Thanks.

Kyle, or I'm sorry, Jonathan?

Yes. We're -- thanks for your question. We're very pleased with the early insights we're getting with the PN launch. As Kyle referenced, we're seeing patients who are used in treatment. We're seeing patients who are switching from existing treatments, and we're seeing patients to having WAINUA added on to their current treatment. So we're super pleased with what we're seeing. It's very early days. This is a foundation year for the launch of WAINUA. But we think there's certainly significant opportunity here when you think through the potential patient population of both PM and CM. The number of patients who are potentially underdiagnosed. And fundamentally, the relatively small numbers today were actually treated. What we're pleased with is that we're seeing prescribing from both neurology and cardiology and both centers of excellence as well as in the community. And that I think bodes well, not just for the PM launch and that progression, but also the transition, obviously, into future indications. Obviously, when it comes to some of those future indications, it's very premature to speculate as to what might happen there. We'll have to wait for future data readouts of our own pretty comprehensive programs.

Yes, two quick things to add. First, on the payer access side of things, we're seeing payers cover WAINUA very quickly. So from the prescription process, the patients actually starting on drug is going very, very well. That tells us that the right types of patients are being identified. And it's also telling us that physicians are justifying the prior authorization process with a sense of urgency, which tells you that these patients need treatment, and they see the value in WAINUA. The second thing I'll just mention is around our patient engagement team. Our PIM team is directly interacting with these patients and getting feedback on a real-time basis. Patients are extremely pleased when they start WAINUA at the ability to self-inject with the auto-injector. Very well tolerated. Very easy to use. Very convenient for those patients and the profile of WAINUA is really playing out the way that we expected it to in the market. Next question please.

The next question comes from Yanan

Great. Thanks for taking our questions. Wondering about what's your takeaway from Roche's recent presentation of their syndrome Phase 2 data at the ASF meeting? And also separately, given the similar development time line our Angelman syndrome program and Astra

Thanks, Yanan. I'll take the first question, then I'll ask Eugene to comment on the primary endpoint and the in primary endpoints for Angelman. So -- we are very pleased to see the data that Roche presented on their Angelman's program. And particularly, we are pleased with the fact that the data further supported our comments ins our Phase 1/2 data that we presented at ASF. Specifically, that the rank order of improvements that they reported with respect to the magnitude of improvement was exactly what we reported. The biggest magnitude that they reported was an expressive communication followed by expressive -- receptive communication, followed by cognition, followed by motor function and so on. And that's exactly what we reported, which get bolstered a further confidence that in our results to date. We are also pleased with the magnitude of benefit we're seeing compared to their program, which really -- it looks like when you really compare apples-to-apples and you convert daily to a outcomes bodes very well. We look like we have even better efficacy at loose compared to what Roche presented. But we were pleased to see what they showed because of the constancy in subdomain benefit between the two programs. Eugene?

Yes. Well, regarding the primary endpoint and conversations to be had the agency, of course, we're looking forward to updating you after we've had our discussions. But there is -- from our standpoint, there's -- this will be data driven. We certainly do believe that the data and consistency of what we see in our Phase 1/2 study gives us a pretty good idea of what we would like to see in a pivotal study, but it's still to be seen what the specific primary endpoint will end up. We'll certainly give you an update. Is there a precedence to have a slightly different or different primary endpoint? Of course, there's plenty of precedents in the neurology space as well as outside. I mean if you look at ATTR CM. That's another example where primary endpoint is not identical for two very similar programs. So stay tuned. We will certainly will be happy to provide you an update.

Thanks, Eugene. Next question.

The next question comes from Jessica Fye from JPMorgan. Please go ahead.

Hey there. Thanks for taking my question. On the back of the top line HELIOS-B data, what's your latest expectation for weather silencers in TTR cardiomyopathy will mainly used in combination with stabilizers versus as monotherapy? Thank you.

Yes, I'd be happy to talk to that. This is Kyle. Thanks, Jessica. The data ultimately is going to drive this, we believe. That is a starting point. I think ultimately, it will come down to physicians and patients making a decision around the profile of treatment that they want in that decision. But when we see it right now, we're seeing -- we knew a used in combination, obviously, as hATTR polyneuropathy indication, combined with cardiomyopathy indication for the stabilizers currently. So we're seeing it happen now. We think that that will continue to progress over time. And we also believe that based on the data and the way the data plays out will be justification for physicians to be able to justify that to payers whenever submit these requests and try to get the drugs approved. So I think it's ultimately data and driven by physicians in patients.

And just to add to that, as you know, Jess, we have -- we're positioned to have the richest data set across the board on primary as well as secondary and some endpoints and subgroups. And we're going to have a great deal of data in combination usage as well as in monotherapy, second to none. And that includes data on key endpoints, clinical endpoints such as hospitalizations, mortality, six minute walk test, biomarkers and so on, but also in the imaging studies. We have several imaging studies in process, and we think that if anyone is going to be able to show really meaningful improvements in combination versus monotherapy across the board, whether the imaging or clinical end points, we're going to be in the best position to do so. And we think that that will, as Kyle said, because this is a data-driven environment. We're going to be in best position to actually have the data to support combination usage. Next question please.

Thank you.

The next question comes from Allison Bratzel from Piper Sandler. Please go ahead.

Hey, good morning guys. And thanks for taking my question. Maybe one on Pelacarsen, since that Phase 3 data and regulatory filings are coming up next year. Could you just talk to or frame what you'd like to see in that readout? And maybe in [indiscernible] what gives you confidence in differentiation of this asset? And what could be a competitive space color on that or the next-gen program would be helpful? Thank you.

Yes, Allison. So there's not -- the only news on Pelacarsen is really that the study is on track to read out as scheduled next year. Everything is going very well. And our partner, Novartis, is well positioned with first mover advantage in this first-to-market patient population has enormous patient population. Everything we're seeing in the Phase 3 study is very supportive. This being set up for a successful outcome. First mover advantage is really important, and we with Novartis are have substantial lead to the market. Yes, the program that -- our follow-on program to Novartis -- with Novartis on the follow-on program is advancing well, maybe I'll ask Eric Swayze to comment on how things are going.

Things are going great. We've been working closely with Novartis. Looking at a variety of ways to extend the dosing interval, and make a great healthy lowering growth. And I'm sure we'll discuss it in sometimes as the program advances further, but I can't really say more than manifest time, but very pleased with the progress we've been making on new technologies, siRNAs in particular, and a broad range of other things beyond what would be amenable for the [indiscernible].

We feel very comfortable that we're going to achieve our objectives with Novartis on a follow-on molecule. Things are going very well. There's obviously a lot of benchmarks out there today. And so there's a lot to compare to. We're pleased. Next question please.

The next question comes from Yaron Werber from TD Cowen. Please go ahead.

Great. And also thanks for taking my question. I also have just a quick follow-up on WAINUA. And as you look at the HELIOS-B data and I'm totally obviously aware that you're probably going to be waiting for the full HELIOS B result. But as you think about with a much powered trial design, where can you potentially differentiate? And how important will that combo data be? Just given that overall [indiscernible] but with broad labor for TTR? Thank you.

Thank you, Yaron. As the largest study ever conducted in this patient population by far, we think we have the opportunity to differentiate in several different areas. It will be very interesting to see the onset of action for silencers and whether or not our onset of action is going to be similar or faster. It's going to be very interesting to see the combination data, as you alluded to just now, and we touched on earlier. Combination data is going to be very important in this patient population and is having a broad label, which we expect to have as well. Cardiologists are data-driven, and they're going to need to see data before advocating for combination usage, I think we're well positioned to have that data. New York health class categories are going to be very important to see how mild patients are doing moderately ill patients and severely ill patients are doing. All this when you have a well-powered study, rich data -- and provide set up to have the rich data set, you have the potential ability to differentiate across the board. Anything to add to that, Eugene?

No, not really, Brett. You characterize it. I think the power really comes from the size of the study and also an ability to look at subpopulations, which were really well visioned to do.

Thank you. Next question please.

The next question comes from Jason Gerberry from Bank of America. Please go ahead.

Hey, guys. Thanks for taking my question. I wanted to come back to the cardio transform timing question. So it sounds like we're going to get pretty detailed and granular data from Alnylam at ESC in terms of multiple curves, on overall mono and subgroups with famous background, including mortality. So it seems like you'll have everything you need to know post AESC on whether or not the 2025 interim is in the cards. So is it fair for investors to get or expect maybe a clear message as of the third quarter update on which way you're going to go as the base case 2026 or whether or not you'll look to 2025 interim? Thanks.

Thanks, Jason. So Ionis and our partner, Astra

Thanks so much.

Next question, please.

The next question comes from Jay Olson from Oppenheimer. Please go ahead.

Hey, congrats on all the progress. And thanks for taking the question. Can you talk about your launch preparation for Olezarsen in FCS? And how should we expect the launch uptake and eventual opportunity in FCS? And also the early access program, how many patients you have? And will those patients switch over to commercial product soon after approval? Thank you.

Yes, thanks for your question. We're really pleased with the progress we're making and have continued to make. Obviously, our preparation started a couple of years ago with the medical affairs team. And subsequent to that, we've built out all the commercial functions that you would expect, whether that's marketing market access, patient support that Kyle referenced. We're trying to build out industry-leading support there for our patients. And to bring you right up-to-date, we've now started hiring and training our field teams ready to engage with customers. So the build has gone very well and is certainly on track, aligned with our regulatory progress, which with breakthrough designation has been at this point, very timely. And that, we think sets us up for a positive launch. Obviously, to your question specifically about the expanded access program, we've got patients, let's be honest, before that, who've been in our pivotal registration studies that are obviously, patients have launched, we hope to provide the opportunity to move on to commercial drug. And the EAP is now in the hands of our medical team and they're talking to customers today. And patients are progressing through the administration or the administrative side of getting access to Olezarsen through that program. So all in all, we are doing a lot of work, as you can imagine, but very much on track to be ready to launch just as soon as the FDA provides approval, fingers crossed. Thanks, Jay. Next question please.

The next question comes from Mike Ulz from Morgan Stanley. Please go ahead.

Hey guys. Thanks for taking the question. Maybe just one on the neurology pipeline with Angelman sort of emerging as your lead program, can you maybe highlight what you view as the next key opportunity there? And if there's any potential read through from what you learned in Angelman's? Thanks.

Eugene?

Yes, sure. Happy to. Thanks for your question. So certainly, we are delighted to have Angelman as service kind of [indiscernible] of the neuroscience portfolio. That is a very rich portfolio following the Angelman Phase 3 program. Just to name a few that are most that bounce currently, certainly, the Olezarsen which is now fully enrolled in its pivotal study. As we recently announced, is the next molecule that we're super excited about. It's an ultra-rare disease. It fits very well with our neurology portfolio. The study is progressing well. There's great feedback from sites and investigator on kind of the quality of the study conduct. And behind

Our wholly-owned neurology pipeline -- thanks Eugene, is positioned to grow and expand in addition to the programs that are in the clinic today. We expect to start two additional wholly-owned neurology programs by the end of this year and more next year, for both rare as well as larger indications, more highly prevalent indications. I also want to highlight the great progress we're making to extend our leadership technologically in neurology. Our most advanced backbone chemistry MSPA will enter -- is expected to enter clinical development and see for a CNS indication later this year, which is focused on reducing dose frequency very meaningfully. We're also making great progress in traversing the blood-brain barrier, using subcutaneous or intravenous infrequent administration. And we're looking forward to maybe our first candidates overcoming the BBB early 2025, and we're looking forward to talking about that as well. So CNS is here and now, and we're leading in this space, and we continue to expect to extend our leader position in CNS going forward. Thanks, Mike. Next question please.

The next question comes from Nary -- I'm sorry excuse me, Gary Nachman from Raymond James. Please go ahead.

Great. Thanks guys. For Doni, when you submit the NDA, what indication will you be looking for in the label? And are you optimistic that switch data will actually be included on the label, which will be so important for these HAE patients? Any chance you could get a priority review or is it likely a standard review? And when will you start building out that commercial team, how much could you fully leverage? What you're doing currently with Olezarsen? Thanks.

Thanks, Gary. Eugene will take the first couple of questions. And then Jonathan we could touch on the build-out of the commercial team.

Yes. With regard to the indication, of course, we're seeking a broad indication for prophylaxis of attacks in rater angioedema and we're pretty comfortable with how things are progressing. Obviously, it is to be determined what the final label looks like and the indications. We are -- sorry, what was the same part of the sub-question?

We've expect that switch data?

Switch data, I'm sorry. And yes, along the same line, again, it's really early to speculate on what the final label is. We will do our best we believe that our program -- our pillar program is very comprehensive, and we also believe that the data that we collected and switch copyists important for physicians to be OR. So we'll make sure that this data is shared broadly, whether it's publication or it ends up in the label, we can't really speculate today.

Yes. And I'll just touch on that a little bit more, Gary. The Switch data is very important, we believe, from a safety standpoint, which we think bodes very well for including it in the label. I mean these patients switch all the time, right? And actually having data that informs physicians on how to safely switch patients such that they avoid getting a gap in their protection in HAE attack is going to be very important. And we think that, that will -- and of course, the FDA is focused on safety and protection against disease progression. So we think that, that bodes very well for us to get in the label. But as Eugene said, it's we don't -- it's risky to get ahead of the regulators on what the label would look like, but we think that we have a pretty good shot at that. Jonathan, how's the launch prep going?

Launch prep is going well. As you can imagine, this is coming hot on the heels of the potential lease launch that we talked about. But the launch prep on the commercial side for WAINUA is well advanced. There are a lot of capabilities that we built. For Olezarsen that we can leverage for Doni, whether that's the medical affairs function, first and foremost, that's been established Olezarsen, that's now leading in the HAE space. We've got brand teams, access teams building out the value dossiers. Patient services is also well advanced and ready to support patients in HAE space and omnichannel as well as a capability that we feel very confident that we've built well at Ionis now and is a capability that's very applicable both to the FCS launch, but also the HAE launch. So there's a lot of synergy there on the commercial side, albeit a lot of that is being appropriately built to best serve each of those launches in the markets and the challenges that they present.

We're also very pleased with the making for submission and preparing for launch in Europe. So stay tuned for them as well. Next question please.

The next question comes from Salveen Richter from Goldman Sachs. Please go ahead.

Good morning, thanks for taking. Good afternoon thanks for taking my question. Could you just speak to the work you're doing here on oligos with next-generation backbones and the other modalities you're looking at and when these programs might enter the clinic? Thank you.

Sure. So as Brett mentioned earlier, the first compound that incorporates our MSPA backbone. We'll enter the clinic for a neurology indication later this year. And the objectives there are to try and extend the dosing interval with the enhanced stability of that backbone, which it provides, and we'll see how it performs. We also have a compound in development with a partner, Astra

Thanks, Eric. And I'll just add to that. So you can expect to see in the not-too-distant future new programs advancing towards development focused on neuromuscular diseases, skeletal muscle, specifically takes further to extend our leadership in neurology. And also, we're pleased with the progress we're making with metagenome on gene editing. We have several programs there that are advancing very nicely preclinically. And I think next year could be a very informative year, a very interesting year in our gene editing program with respect to new information coming out as to what our strategy is and what our first molecules will be. So stay tuned for that. We're making great progress across the board in diversifying in expanding our technological capabilities. And with that, I think we have time for one more question.

The next question comes from Kostas Biliouris from BMO Capital Markets. Please go ahead.

Hello, thanks for taking our question. And congrats on the progress. Can you talk a little bit about the CARDIO-TTRansform enrolled population? And specifically the differences between the geographies and the follow-up from the originally enrolled population and the population who were enrolled after the changes you made to the statistical design? And if you expect any impact from the differences between these two populations? Thank you.

Thanks, Kostas. So we have, of course, having shared the demographics for our CARDIO-TTRansform study. We look forward to doing that in the future. We really are pleased with the enrollment in the study. And as we've said, we have a nice balance in this big study, the largest study were conducted in TTR cardiomyopathy, nice balance between monotherapy patients as well as patients on combination treatment. We're also very pleased with very small percentages of drop-ins and families in the study. It's going exactly as planned. We're pleased with the percentages of patients we have with New York Health Class 1, 2 and 3 in the study. And we -- everything we've seen that has come out in this space with respect to other people's patient demographics supports our decision to expand our study to take into account for a patient population that's being diagnosed much earlier in their disease. So we couldn't be more pleased with the way the study is going, including our patient demographics. So thanks for the question, Kostas. I think we have -- it's time to wrap things up. I really want to thank everybody who joined us today for your participation and your questions. We're very proud of everything we've accomplished the past quarter, first half of this year. And we're planning to build on this momentum to achieve even greater successes in the second half of this year. And we're very much looking forward to providing the updates on the progress we continue to make this year as well as into next year. So thank you very much, everybody, and have a great day.
