Once our call concludes, the IR team will be available to answer any further questions. With that, let me turn the call over to our President and Chief Executive Officer, Dr. Leonard Schleifer. Len.

Thank you, Ryan, and welcome to everyone joining our call today. We're pleased to report another quarter of strong performance driven by outstanding commercial execution and a large and diverse pipeline that is continuing to deliver on its promise. Total revenue grew 36% and non-GAAP earnings per share grew 70% compared to the third quarter of 2025. This marks our third consecutive quarter of double-digit growth on both the top and bottom lines. Our commercial teams continue to execute at a very high level. Dupixin, Hylia HD, and Liptio each set new all-time highs for quarterly net sales for the second quarter in a row. Dupixin global net sales in the third quarter, as reported by Sanofi, reached a record $6.5 billion, up 35% year-over-year at constant currency, which is truly remarkable for a medicine approaching 10 years on the market. In the U.S., where Dupixent is the leading biologic in eight of its nine FDA-approved indications, quarterly net sales grew 40% and exceeded $5 billion for the first time, primarily driven by robust demand across all indications, as well as gross-to-net favorability, as disclosed by Sanofi. ILEA-HD quarterly net sales in the U.S. reached a new all-time high of approximately 700 million, up 62% from a year ago, and now represent nearly two-thirds of our U.S. retinal franchise. Physician unit demand grew 20% sequentially, reflecting the value retinal specialists and their patients see in extended dosing intervals, as well as last year's label enhancements, which added the retinal vein occlusion indication and greater dosing flexibility. We remain optimistic for approval of the pre-filled syringe before the end of the year, and we expect it to drive even further adoption if approved. Liptio is making important differences for patients with skin and lung cancers, and it continues to build clinical and commercial momentum. In the U.S., it is the leading immunotherapy in non-melanoma skin cancers and the second most prescribed immunotherapy in non-small cell lung cancer. Global net sales reached a record $550 million, up 51% in constant currency, and U.S. net sales grew 81% to nearly $400 million. Last week at ESMO, we presented longer-term data from our Phase III C post-trial, showing an increasing overall survival benefit with adjuvant Libtio in high-risk cutaneous squamous cell carcinoma, where it is the first and only approved immunotherapy. Liptio is now on an annual run rate of approximately 2.2 billion and remains the foundation for our broader oncology strategy. Beyond our strong commercial execution, our pipeline is poised to deliver several potential blockbuster opportunities over the next several years. Let me highlight new advances in four of our pipeline programs while George will discuss in more detail along with other late-stage clinical programs, including Factor XI, Linazific, and Otorepetide. In neuromuscular disease, we expect an FDA decision in November for Simdisiran and generalized myasthenia gravis. If approved, Simdisiran would be the first siRNA therapy for generalized myasthenia gravis and the only treatment that can offer quarterly subcutaneous dosing. Early in my career as a neurologist, I cared for many patients with this difficult-to-treat condition, so it is particularly gratifying to see us bring forward a potential new treatment option for them. In metabolic disease, MASH affects millions of people and treatment options are limited. Our Side B program is a great example of our genetics-driven scientific process. Regeneron Genetic Center discovered that people with naturally occurring loss of function variants of the Side B gene have a markedly lower risk of fatty liver disease and cirrhosis, which led us to develop a first-in-class sRNA that targets Side B. We are encouraged by the initial clinical data, which suggests best-in-class, best-in-disease potential, and we are rapidly advancing this program into registration-enabling studies. I'd also like to highlight our program for postural orthostatic tachycardia syndrome, or POTS. This is an increasingly recognized debilitating condition that affects many young people, often disrupting school, work, and daily life with very few effective treatment options and no FDA-approved medicines. Recent estimates suggest that between 500,000 and several million people in the U.S. alone suffer from PAS. We believe the initial clinical data that George will highlight supports our antibody's potential to become the first FDA-approved treatment for this disease, and we plan to initiate a potentially pivotal study next year pending regulatory feedback. In oncology, we recently shared encouraging data for the Ubimanumab, our MUC16 by CD3 bispecific antibody, an advanced low-grade serous ovarian carcinoma. This is a rare and difficult to treat form of ovarian cancer that often affects younger women who urgently need better treatment options. We saw durable responses in heavily pretreated patients at rates well above those historically seen with available therapies. We are already enrolling a dedicated, potentially registrational cohort and plan to start a confirmatory phase to be studied next year. Each of these programs is supported by compelling clinical data, human genetic validation, or both. It is no accident that they span four distinct therapeutic areas and that each has first-in-class or best-in-disease potential. That reflects our disease-agnostic enterprise approach to R&D. Rather than confining ourselves to a few therapeutic areas, we apply our core technologies wherever the science leads us. These technology platforms, including our Velocimune antibody and bispecific engines, Regeneron Genetic Center, and siRNA and gene editing technologies that allow us to translate genetic discoveries like Side B into potential medicines. Today, that approach supports approximately 50 clinical programs spanning immunology, oncology, ophthalmology, hematology, cardiovascular and metabolic diseases, neurology, and Rare Diseases. Our commercial organization has been built the same way. Our teams already call on ophthalmologists, dermatologists, pulmonologists, allergists, gastroenterologists, ENT specialists, oncologists, cardiologists, and hematologists. And if Semdiseran is approved, we will begin to call on neurologists as well. That means many of our pipeline medicines, including several of the programs I just mentioned, can launch into specialties where we already have deep relationships and expertise and can leverage our existing infrastructure and capabilities. Briefly on business development. Historically, we have been a net outlicenser of innovation, with the most recent example being the expansion of our alliance with Sanofi. We are contributing to the alliance for next-generation long-acting antibodies, all invented at Regeneron, that target the same pathways that made Dupixent so successful. Regeneron will lead research and development, and Sanofi will lead global commercialization, now with greater transparency and increased participation by Regeneron. If approved, these medicines can also benefit from Dupixent's commercial leadership and the strong market access position it has established, an advantage neither company could capture on its own. At the same time, our financial strength positions us to bring differentiated external innovation into Regeneron. We've done this effectively to date, primarily through early-stage research collaborations, including those that built our emerging genetic medicines pipeline across sRNA therapeutics, gene therapy, and gene editing. We continue to evaluate a wide range of opportunities, from early clinical programs and platforms to commercial-stage products with a sharp focus on valuation and strategic fit. In closing, this was an exceptional quarter by every measure. Our three core growth brands are performing at record levels and our expanded alliance with Sanofi positions us to lead the next era of type two inflammation medicines. Our pipeline is poised to deliver additional potential blockbusters across a broad range of diseases and our commercial organization is built to bring them to patients. Our future is bright and we remain focused on translating our science into new medicines that can make a meaningful difference for patients and create long-term value for shareholders. With that, let me turn the call over to George.

Thanks, Len. For my remarks today, I'll first provide further details on the four programs that Len highlighted. then cover other key updates from our pipeline. Beginning with our C5 program. Regulatory submissions are under review for simdisarine or C5 sRNA for generalized myasthenia gravis or GMG. An FDA decision is expected next month and a European Commission decision is anticipated in the second half of 2027. If approved, simdisarine would be the first and only siRNA therapy approved for GMG. It would be distinguished by a combination of rapid onset, consistent efficacy throughout the dosing interval, manageable safety, and convenient subcutaneous dosing just four times per year. Our C5 program also includes a co-formulation of some discerne with poselamab, our C5 antibody that's already FDA approved for protein losing enteropathy. Together, they are being evaluated as a combination therapy for paroxysmal nocturnal hemoglobinuria, or PNH, where we expect to report pivotal results by the end of the year. Initial results from a lead-in cohort of the Phase III trial suggest that our novel combination approach could provide best-in-class control of intravascular hemolysis. Our C5 program further includes evaluating some discerin with and without pozolomab in geographic atrophy, or GA. via systemic administration. We now expect to report interim 26-week data from an exploratory cohort of our ongoing Phase 2-3 study in early 2027 where we hope to see a trend towards slowing of lesion growth comparable to the approved agents at a similar time point. A potential advantage of our systemic approach is the ability to treat bilateral disease, which affects many patients, while avoiding the potentially devastating ocular safety events seen with certain FDA-approved agents that are delivered intravitrally. In addition, we are exploring our own intravitreal administration of prezolomab, which might also offer safety advantage over currently approved therapies. Moving to MASH. At the upcoming liver meeting in November, we will present first in human data for our siRNA for PsiB. This target was discovered by our Regeneron Genetics Center which identified side B's unprecedented ability to protect against liver fat and liver disease through our large-scale human genetics database. In the initial data from 40 participants, a single dose was well-tolerated and reduced liver fat by approximately 70% on average from baseline in just 12 weeks, bringing mean liver fat to near or below upper limit of normal at every dose level tested. This effect was durable through 24 weeks of follow-up and was accompanied by improvements in liver enzymes consistent with reduced liver cell injury. These results not only clinically validate the side B discovery from the Regeneron Genetic Center, but suggest that we have a breakthrough new approach that directly addresses a genetic driver of MASH and could benefit the millions of MASH patients underserved by current approaches. We are working to rapidly advance to registrational trials and look forward to sharing more about this agent at our next Regeneron Roundtable Investor Event scheduled for November 10th. Moving to postural orthostatic tachycardia syndrome or POTS. This disease appears to be driven by chronic pathological depletion of intravascular volume. Current treatments include salt and fluid administration which provide only short-term relief. There are no FDA approved therapies and off-label treatments are generally unsatisfactory. At the American Autonomic Society Congress in November, we will be reporting results, initial results from our Phase II study. After a single treatment with high-dose balance of ART, we saw improvements in the two key endpoints for this disease, tachycardia and orthostatic symptoms, sustained over four weeks from a single dose. These improvements appear to be associated with durable restoration of intravascular volume. We are planning to initiate a potentially registrational study in the first half of next year, pending regulatory feedback, and we believe this could be a game-changing treatment for a debilitating disease with significant unmet need. Next, turning to Ubimatumab, our MUX-16 bispecific antibody in development for ovarian cancer. which was featured in a late-breaking plenary session at the International Gynecological Cancer Society meeting. The data presented there, along with additional data, indicate that uvimatumab monotherapy has an approximately 70% objective response rate with prolonged progression-free survival in women with advanced low-grade serous ovarian cancer with an acceptable safety profile and no biomarker selection required. To put this in context, Chemotherapy and endocrine therapy have historically delivered response rates below 15% in this setting, and the only approved therapy achieved a 44% response rate, but only in the roughly 30% of patients with low-grade serous ovarian cancers who tumor carry a specific biomarker. Based on these encouraging early results for uvimatumab, we're enrolling a potentially registrational cohort and plan to start a confirmatory phase 3 trial in mid-2027. Turning now to our larger late-stage programs and starting with Linazific, our BCMA by C3 bispecific. We believe Linazific is differentiated not only by the efficacy demonstrated in late-line multiple myeloma, but also by our development strategy, which creates important new opportunities in first- and second-line settings and even in pre-malignant disease, with pivotal readouts beginning next year. In 2027, we expect initial results from our confirmatory trial of linazivic monotherapy versus standard of care in patients with multiple myeloma who received at least one prior line of therapy. In 2028, we expect initial results from our first line study in transplant ineligible patients, as well as from our linazivic carfilzomib combination study in patients who received at least one prior line of therapy. We're also enrolling potentially registrational cohort in second line Light Chain Amyloidosis, and plan to start a Phase III study in first-line Light Chain Amyloidosis by early 2027. In addition, we are actively enrolling a Phase III trial in high-risk smoldering myeloma. We also have a differentiated development strategy for Odrenextamab, our CD20 by CD3 bispecific. We have a regulatory application under FDA review for relapsed refractory diffuse large B-cell lymphoma with the February 2027 target action date. Importantly, we expect results in 2028 from our fully enrolled phase three study of OGEN-XMF monotherapy in first-line follicular lymphoma, which could provide these patients who have high unmet need with the first bispecific and chemo-free immunotherapy option. Moving to anticoagulation. For Factor XI inhibition, we continue to favor Our antibody approach over small molecules because antibodies may enable more potent and specific inhibition with the potential to improve antithrombotic activity without increasing bleeding risk or introducing off-target safety issues. Our program features SINVASIBAR, our catalytic domain antibody, and MRESIBAR, our AT domain antibody. I'm pleased to report that all but one of the planned Phase III studies are now enrolling patients. These studies span venous thromboembolism prevention after total knee replacement, stroke prevention in patients with atrial fibrillation, cancer-associated thrombosis, peripheral aortic disease, and most recently, venous thromboembolism prevention in patients with peripherally inserted central catheters. The one remaining phase three study yet to initiate in secondary stroke prevention is expected to begin enrollment by year end. We expect pivotal results from our knee replacement program Starting next year with other pivotal studies expected to read out in 2028 and beyond. Turning to allotorepetide, our dual GLP-1 GIF receptor agonist in license from Hanzo. Recently, Hanzo presented encouraging efficacy, safety, and tolerability data from their Phase III trial in patients with obesity in China at the European Association for the Study of Diabetes Conference. We look forward to starting our global Phase III program We believe this could provide an important new treatment option for the many patients with obesity and type 2 diabetes who comorbidly also suffer from hypercholesterolemia and increased cardiovascular risk. And we plan to begin registrational studies of this combination next year. As Len discussed, we recently announced an expansion of our alliance with Sanofi. Building on the success of Dupixent and the validation of the IL-4 and IL-13 pathways as central drivers of type 2 inflammation, the Alliance is advancing Regeneron's four fully human, velocimine-derived, long-acting antibodies and bispecifics. These candidates are designed to preserve Dupixent-like efficacy and safety while enabling substantially less frequent dosing. All four candidates avoid the heavy engineering that tends to compromise biopharmaceutical properties or raise the risk of anti-drug antibodies. Our candidates, which are fully human and non-engineered, also share important molecular properties, so learnings from one should carry over to the others and potentially support an expedited development. Our first in-human trial for our lead IL-13 antibody, which has a target dosing interval of every three to six months, is currently enrolling with patients with atopic dermatitis. with registration of trials expected to begin in late 2027 and 2028. Three additional programs, a long-acting IL-413 bispecific, a long-acting antibody to IL-4 receptor alpha, and an IL-4 ligand antibody are expected to enter the clinic next year. Relevant to these programs, I want to end by reminding you that we have previously shared early clinical results for our BCMA by C3 bispecific in combination with dupixin in severe food allergy. These results strongly supported our hypothesis that food allergies could potentially be cured by rapidly and completely depleting plasma cells which produce immunoglobulins including the allergy-causing IgEs and then continuously suppressing the return of IgE antibodies by blocking IL-4 and IL-13. While the BCMA by CD3 eliminates plasma cells producing all classes of immunoglobulins, we have invented a new bispecific antibody that selectively eliminates only the IgE-producing and allergy-causing plasma cells. We plan to build on our groundbreaking results combining our BCMA bispecific with Dupixent by expeditiously pursuing this more targeted approach with clinical studies of this new bispecific antibodies to start in the first half of 2027. In summary, we have strong momentum across our broad and diverse pipeline that we believe that has the potential to change the practice of medicine across many diseases with high unmet needs. With that, let me turn it over to Marion.

Thank you, George. Our third quarter results reflect strong commercial execution across our portfolio with our largest brands achieving new all-time highs in net sales. Our team is also focused on recent and upcoming launches with Passatru now approved in the U.S. for ultra-rare FOP, and we are preparing for the November PDUFA for some discerin in generalized myasthenia gravis, starting with Depixent, which continues to deliver transformative benefits to patients across nine type 2 inflammatory diseases with more than 1.5 million patients currently treated worldwide. In the U.S., Depixent remains the most prescribed branded biologic among dermatologists, pulmonologists, allergists, and ENTs. and many more. reported by its best-in-class clinical efficacy and safety profile. Uptake is also strong in our more recently launched indications of COPD, pyraganodularis, chronic spontaneous urticaria, bolus pemphigoid, and allergic fungal rhinocytosis, with continued growth in new-to-brand prescriptions. With significant opportunity for future growth across all nine indications, Dupixin is well-positioned over both the near and long term. Additionally, we are excited about the recently announced expansion of the Regeneron Sanofi Alliance and to continue building on the strong foundation we've laid together with Depixent. Turning to our retinal franchise, in the third quarter combined, ILEA HD and ILEA US net sales were $1.1 billion, down 1% compared to last year, with ILEA HD now comprising nearly two-thirds of the franchise net sales. Third quarter ILEAHD net sales in the U.S. were $699 million, up 62% versus prior year. These results demonstrate strong physician unit demand, which grew 20% from the second quarter. This growth is driven by the ongoing benefit of recent label enhancements, which have increased adoption and broadened use of ILEAHD across the spectrum of retinal practices. Physicians increasingly recognize ILEA HD as the best-in-class product in the anti-VEGF category based on its efficacy, safety, and durability. ILEA U.S. net sales were $400 million for the quarter, a 41% decrease versus the prior year. Sequential physician unit demand declined by a high single-digit percentage compared to the second quarter, with this decline partially offset by favorable gross-to-net adjustments. Both ILEA HD and ILEA benefited modestly from the timing of end-of-quarter shipments. Looking ahead to the fourth quarter, we expect continued ILEA HD momentum with sequential physician unit demand growth of approximately 10%, partially offset by ongoing pricing pressure, resulting in full-year net sales growth of over 50% compared with 2025. For ILEA, we expect a sequential demand decline in the low to mid-teens in the fourth quarter. Overall, the franchise remains in a strong position despite increasing competition from additional Flibercept 2 mg biosimilar launches, and we look forward to potential FDA approval of the ILEA-HD pre-filled syringe to help sustain ILEA-HD momentum in 2027 and beyond. Turning to Libtaya, which delivered worldwide net sales of $550 million, up 51% year-over-year on a constant currency basis, and the U.S. net sales were $396 million, up 81%. In non-melanoma skin cancer, Libtaya continues its strong trajectory as the leading immunotherapy. In the U.S., the recent approval on adjuvant CSE is helping to drive growth and is changing the treatment paradigm. Leptio remains the only NCCN Category 1 preferred immunotherapy option for eligible patients and ongoing formulary wins are driving increased usage. In non-small cell lung cancer, Leptio remains the second most prescribed immunotherapy as physicians increasingly recognize its strong clinical profile. We continue to build on Leptio's strong momentum by enhancing the patient experience through extended dosing and shorter infusion times across all approved indications. We recently received a positive CHMP opinion for every six-week dosing for Liptio along with an infusion time as short as 15 minutes. An SBLA for this updated dosing regimen is under review with the FDA with a decision expected by March 2027. We expect continued growth for Liptio as we gain incremental share in lung cancer and drive uptake in adjuvant CSCC. Onto lenazific and multiple myeloma, physician feedback on the currently approved late line setting remains positive based on lenazific's differentiating efficacy and safety profiles, lower hospitalization requirements, and convenient dosing. Despite its strong profile, we expect lenazific growth to remain modest as we work to advance into earlier lines of therapy. We are also building Regeneron's severe disease portfolio, serving patients with significant unmet need FKESA continues to grow in its sixth year on the market with U.S. net sales of $55 million, up 28% versus the prior year. We have also expanded our portfolio with the recent launches of What Harmony for genetic hearing loss and Pass the Truth for FOP. Initial progress for both brands is promising, and we look forward to helping patients suffering from these devastating diseases. Finally, in neurology, we're preparing for the potential launch of Subdisrin and generalized myasthenia gravis, which has a November PDUFA date. We see significant commercial opportunity for some discerin based on three key factors. It's novel siRNA modality, rapid onset and durable efficacy without the waning treatment effect observed with many other approved therapies, and convenient four times per year subcutaneous dosing. In closing, our third quarter results reflect strong commercial capability across therapeutic areas. We've built an effective commercial infrastructure that enables us to execute across both inline brands and new launches. As Len mentioned earlier, our commercialization platform currently spans nearly every relevant specialty, and this market experience positions as well for the many potential new products from our pipeline. Whether a common or rare disease medicine, specialty or internal medicine prescriber, medical or pharmacy benefit product, we are confident in the capabilities of our commercial organization in both the near and longer term, and with that, I'll turn over to Chris.

Thank you, Marion. My comments today on Regeneron's financial results and outlook will be on a non-GAAP basis unless otherwise noted. Regeneron delivered a strong third quarter, once again reaching double-digit growth on both the top and bottom line, driven by some sustained momentum across our key growth drivers and solid execution throughout the business. Third quarter total revenue increased 36% from the prior year to $5.1 billion. driven primarily by higher Sanofi collaboration revenue along with strong growth from both Libtyo and ILEA-HD. Third quarter, diluted net income per share grew 70% to $20.07 on net income of 2.2 billion. Beginning with the Sanofi collaboration, third quarter collaboration revenues reached an all-time high of 2.7 billion, including 2.6 billion from our share of collaboration profits. Our share of profits increased 77% versus the prior year, primarily driven by continued Depixent net sales growth and the repayment of the Sanofi development balance, which was completed in the second quarter. Consequently, in the third quarter, we recorded our full share of collaboration profits for the first time. Under the recently amended antibody collaboration, Regeneron and Sanofi will share equally the development and commercialization costs of four next-generation antibodies. since R&D costs will be co-funded as they are incurred, there will be no R&D development balance. Global profits from these antibodies will also be shared 50-50 while the existing economic terms for Depixin and Kevzara remain unchanged. Regeneron expects to record the full $1 billion upfront payment as Sanofi collaboration revenue in the fourth quarter with any future milestone payments recognized in full in the period achieved. Moving to Bayer. Third quarter net sales of ILEA 8MIG and ILEA outside the U.S. were $643 million, inclusive of $384 million of ILEA 8MIG sales. Total buyer collaboration revenue was $267 million, of which $212 million related to our share of net profits outside the U.S. Other revenues in the third quarter increased 57% year over year to $310 million, including $253 million from our share of Arculus Profits and Alaris Royalties. Third quarter Alaris royalty revenue included an approximately $60 million cumulative catch-up adjustment reflecting the application of the highest royalty tier on year-to-date sales. This cumulative catch-up will not recur in the fourth quarter. Now to our operating expenses. Third quarter R&D expense was $1.7 billion driven by continued advancement of our broad clinical pipeline as well as the timing of related clinical manufacturing. Third quarter SG&A was $588 million, an increase of 9% year-over-year, reflecting investments across our commercial organization and broader business. Our third quarter effective tax rate was 15%. The year-over-year increase was primarily due to a shift in the geographic mix of our pre-tax income driven by higher Sanofi collaboration revenue. Regeneron generated $2.9 billion of free cash flow through the first nine months of 2026 and ended the quarter with $16.2 billion of cash and marketable securities net of debt. In the first nine months of 2026, we deployed nearly $3 billion across share repurchases, business development, and dividends. This included $2.3 billion to repurchase 3.2 million shares. We expect full-year share repurchases to total approximately $3 billion, and as of September 30th, we had $2.2 billion remaining under our repurchase authorization. Moving to guidance, we made modest refinements to our 2026 financial guidance as we enter the last quarter of the year. A full summary of our guidance can be found in our earnings press release published earlier this morning. As we look to 2027, Len and George discuss the meaningful progress we are making across our innovative pipeline. We expect to advance multiple large registrational programs in myeloma, anticoagulation, obesity, and emerging mid-stage opportunities with significant revenue potential, such as our programs in POTS and MESH. This year alone, we are on pace to initiate more than 15 Phase III trials. We believe these investments can create substantial long-term value. To support this progress, we currently expect 2027 R&D expense to increase by a mid-teens percentage compared with 2026. Regarding our 2027 effective tax rate, we expect approximately 100 to 200 basis points of upward pressure relative to 2026, consistent with our prior long-term tax rate commentary. Finally, turning to the new barter agreement for Inmazeb, Beginning in late 2027, we expect to supply additional treatment doses to the U.S. government through 2031. Therefore, we do not anticipate recording any revenue in the fourth quarter of 2026 for Amazep. In conclusion, we delivered another outstanding quarter and remain well-positioned to invest in our differentiated pipeline, deliver important medicines to patients, and create durable long-term value for shareholders. With that, I'll pass the call back to Ryan. Chris.

This concludes our prepared remarks. We will now open up the call for Q&A. To ensure we are able to address as many questions as possible, we will answer one question from each caller before moving to the next. Shannon, can we please go to our first question?

Thank you. To ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11 again. Our first question comes from the line of Salveen Richter with Goldman Sachs. Your line is now open.

Hey, good morning. Thank you for taking our question. This is Elizabeth Webster on for Salveen. Just ahead of AASLD, could you further frame the clinical data from Side B we've seen to date in the context of the competitive landscape and expand upon where Regeneron would position this asset? And in your view, what are the key aspects of differentiation? Also noting you will speak about this at the roundtable, but any color you can share now would be appreciated. Thank you.

Well, the other approach is to Thank you very much. Similarly, the product from Madrigal works by a separate mechanism as well. This is the first pathway that directly involves a genetically validated target that is central to protecting the liver against multiple liver diseases, including liver fat generated diseases. Reflecting the genetics and the specificity and importance of this pathway, The liver fat reductions that one is seeing here are unprecedented in the rapidity of onset and the depth of the liver fat reductions. As we said, they're on the order of 70% achieved in just a few weeks, and this is with a single dose lasting for a very long period of time. These are really game-changing results, and of course, highly supported with the genetics. So, of course, we've reproduced now the genetic effects on liver fat. This gives us even more confidence that we're going to reproduce the genetic effects on benefits in terms of liver disease. So this is really game-changing, unprecedented. There's nothing like this before for this disease, and I think it's reflective of our approach to using large-scale human genetics to actually define the underlying mechanism of disease and not just come up with drugs that sort of accidentally or by chance also benefit a disease of interest, but actually defining the underlying genetic pathway causing the disease, directly targeting with one of our signature platforms, in this case the siRNA approach, and producing unprecedented results in these early-stage data.

Thanks, George, and we certainly look forward to highlighting that in a couple weeks at our roundtable event on November 10th. Shannon, let's move to the next question, please.

Our next question comes from the line of Brian Abrahams with RBC Capital Markets. Your line is now open.

Hey, guys. Good morning. Thanks so much for taking my question here. I wonder if you could talk a little bit more about the CIMDISRA and pre-launch activities, just kind of some of the learnings there as you prepare for the launch. Now that you're close to the approval and a potential label, and just how you're thinking about the initial target audience and uptake. Thanks.

Sure. Very happy to make comments. So we certainly have a very talented neurology team at Regeneron. Very pleased with the caliber experience that the team has in neurology with other programs, and now we're really excited to bring that to Regeneron. The, as we mentioned, PDUFA date in November, very exciting. So launch activities, preparation are well underway. I'm not going to say a lot about launch strategy, but delighted to talk about it in the future. But I'm certainly sure, everyone, that we are launch ready. We look forward to the label and certainly bringing some Disren into the marketplace is a really important enhancement for patients who need this treatment.

Thanks, Marion. Let's move to the next question, Shannon.

Our next question comes from the line of Akash Tiwari with Jefferies. Your line is now open.

Hey, thanks so much. I noticed that your Sanofi collaboration allows you to add another early-stage Sanofi asset. Can we revisit, you know, STAT6? If the STAT6 orals start to deliver efficacy, not better, but let's just say similar to the Pixin, would that be an asset that your team would be interested in adding to the ongoing collaboration with Sanofi. Thank you.

Yeah, so look, the Alliance is open to doing anything and everything that makes sense to build on our expertise. I think the oral agents are an interesting class, but they're a long way from giving the efficacy and safety that 2-Pixen pathway blockers would give. You're talking, as you further get away, from the membrane and downstream. You always have to deal with other potential activities. And frankly, when you get into longer dosing intervals, a daily pill doesn't afford much of an advantage in convenience and maybe even have to take it more than once compared to something that you might take once a quarter, once every six months. So the bottom line is I think the alliance is open. We have a very good relationship now with Sanofi, I think we're back on a very strong track. Leilin Griho has been really clear-cut in helping us frame that we want to continue to build on Dupixent for a long time.

Yeah, I think we should add that certainly there may be room for multiple treatment options and ways at dealing with the patients with so much high unmet need out there. But certainly, as Len said, an injectable that can be given two or four times a year will certainly be an incredibly attractive option for so many patients, whereas, of course, there may also be room for an oral pending, of course, dealing with the efficacy and, of course, safety issues that Len raised.

Thank you, guys. Next question, please, Shannon.

Our next question comes from the line of Tyler Van Buren with TD Cowen. Your line is now open.

Hey, guys. Good morning and congratulations on a very, very impressive quarter. So is it fair to say that Regeneron will become even more aggressive on the business development front than it was a year ago given the long-term new product revenue incentives stretching up to $30 billion to $40 billion? What stage of development is the ideal time to acquire external assets in your view? Is it post-phase two, so you can have a hand in operating the phase three, or is it post-phase three when you're closer to commercialization?

Yeah, so Tyler, that's a great question. We do appreciate the two varies in your introductory remarks. I think our records show you've only given us one vary in the past, so thank you for that. In terms of business development, look, we look at the overall spend on investment, if you will, on research and development. And when you add up what other companies spend on external innovation and internal innovation and what we spend on internal and external innovation, these numbers, we're not out of line at all. It's just that we have this incredibly productive research effort that George detailed a little bit that is producing things where some of the things we haven't even talked about and Aaron in the clinic yet are still even more exciting than you can imagine. So we are open to any and all opportunities at all stages. But as I said in my remarks, we're focused on the science. Does it really make sense? We love platforms if we can get platforms. But we have the firepower to do an advanced product. or an early stage. So we are sort of agnostic. We don't really manage our BD in that, hey, we need to fill a phase two slot or phase three slot. We're looking for things that can make a difference to patients and build and interact better with and be better with us than they might be by themselves.

I need to add to what Len just said. I think that every company looks internally and externally at and tries to evaluate which are the best opportunities for them to take on. And unfortunately for most companies, they end up deciding that they have to look outside for the best opportunities compared to what's coming through the pipeline. As Len just described, most of the time when we compare almost all external opportunities to what we have coming internally from our R&D engine, we choose to focus to spend our resources on the internal opportunities when we compare them to what we get from the outside. If you evaluate the track history of the industry in licensing outside opportunities, I think you would realize that our track record tends to outperform the industry standards for in-licensing by far. Good point.

Thank you. Let's move to the next question, please, Shannon.

Thank you. Our next question comes from the line of June Lee with UBS. Your line is now open.

Hi. Congrats on a very strong quarter, and thanks for taking our questions. You have four very promising next-gen doopies based on patent filings. Do you need just one to succeed, or do you have different plans for different antibodies for different indications?

Thank you. That's a great question. I think that one of the reasons that we have these four assets is that we can actually imagine, as you say, that some might be better tailored for one setting versus another setting. And so our development plan is certainly anticipating that possibility.

Okay, thank you. Next question, please.

Our next question comes from the line of Tazeen Ahmad with Bank of America. Your line is now open.

Hi, good morning. Thanks for taking my question. I just wanted to get your updated view on the competitive landscape in AD, especially as it relates to next-gen assets. You've talked about the importance of having long-acting treatment. Do you think that's going to be sufficient to be competitive in the long run, just given that others might also try to have similar dosing frequencies? Or do you think showing improved efficacy over DUPI is also going to be needed? Thanks.

Well, let me comment on the commercial side. But showing efficacy over DUPI reminds me of the number of people that have tried to show efficacy over ILEA over the last 15 years. very difficult to do, and I think the same will be true for our side B and other things that George talked about, because when you get to the heart of a problem, it's tough to really improve on mechanism. That said, I think while others might be able to do long acting as we are, there's room for multiple entries in this space, but very few will have the experience, the leverage, the capabilities that Sanofi and Regeneron have put together with their experience with DUPI. I don't know, Marion, if you'd like to.

Well, let me just add one point to the competition. So, and I think it's a really, really important point. In order to achieve long-acting, if you look at the competition, they're using heavily human-engineered versions of previously existing old antibodies that were generated decades ago. And when history shows, if you look across the industry, human engineering is generally results in more problems than advances in terms of issues, for example, with drug antibodies and so forth. So our approaches, remember, depend on a very natural system, all derived naturally from our almost magical genetically engineered mouse that's fully humanized that delivers these, requiring almost no human intervention and engineering. So history shows, based on our own track record, that our naturally derived antibodies tend to outperform heavily engineered antibodies. So while others are trying to do what we're doing, we'll have to see how these heavily engineered versions will compare to what we've historically delivered and tend to perform very well in patients. Go ahead, Mary.

So from commercialization, it's the platform that George and Len described on the differentiation of our science, which results in efficacy, safety, and potential advancements on dosing frequency. But today, it starts with Depixent, where across nine indications, age groups, geographies, Depixent time and time again has shown itself to be the product with best efficacy across type 2 diseases, remarkable safety, and tremendous results for patients. From a commercialization standpoint, we look forward to these next programs. As George described, it all starts with the differentiation of our science.

Thank you. Next question, please, Shannon.

Our next question comes from the line of Ellie Merle with Barclays. Your line is now open.

Hey, guys. Thanks for taking the question and congrats on the quarter. On the MASH program, interesting on the 70% liver fat reduction, and we certainly agree that MASH is a very large opportunity. Curious for perspective on the anti-fibrotic mechanism that you might be seeing here, and how are you thinking about this in the context of the FGF21 class? I guess from your look at the genetics, do these point to a mechanistic rationale in F4 cirrhosis, or would you be focused more on the F2, F3 fibrosis setting? And then you alluded to moving into registrational studies here. I know there's been an evolving discussion at the FDA on non-invasive markers versus histologic endpoints. Just curious your perspective and strategy here in thinking about the target patient population and potential next steps. Thanks.

It was a little hard to hear you, and there was a lot of questions in there. But the bottom line, and you can read our published data on the genetics, in terms of this pathway seems to protect against multiple aspects of liver disease, including that driven by fat, but by other mechanisms as well, with the effects represented in all facets of the resulting subsequent liver disease. So we feel that this mechanism may be getting at the heart and driving of many aspects of the liver disease that the world would like to be preventing, and no other pathway has shown this sort of genetic protection profile. So that's what makes it so exciting, together with the fact that the early clinical data actually are mirroring what we see genetically, which is giving us even more confidence in the genetics. In terms of registrational trials, as we said, we are moving aggressively forward in this program and we'll be talking more at the November 10th Roundtable where we can give you a lot more details.

Thanks, George. Next question, please, Shannon.

Our next question comes from the line of Gregory Renzo with Truist Securities. Your line is now open.

Greg, good morning, everyone. Congrats on a tremendous quarter, and thanks for taking my question. Len, you certainly touched on, along with the team, the advantageous breadth of your presence across specialties, therapeutic areas. My question is, at what stage do you see that versatility perhaps presenting a challenge or even a risk to the execution and the depth that you want Regeneron to have? And maybe relatedly, as you talk about electrolyte and opening up a 3,000-patient trial, to what extent are you and the team willing to make an investment in the vast obesity space and the resources that are in demand for winning there? Thanks so much.

Very good question, Greg. It seems as though you may have been sitting in on some of our internal discussions. This is something that concerns us a lot. How do we make sure that our best-in-class opportunities in drugs get adequately developed, compete well, both in the development as well as commercialization? I can tell you we are very focused on that, but our experience matters. As I think we tried to get across, We have developed drugs for eye diseases, for cancer, for endocrinology, for ENT, for gastroenterology, for allergists and so forth, pulmonologists. We have this experience of working with the specialists that we need to. We have a great diverse group that George leads internally. I think we can do it. Doesn't mean we're going to be perfect. but we are going to strive to, anything we take on, we're going to take on wholeheartedly. And I think we do now have the experience that it's going to take. George, you want to add to that?

Yeah, I remind you, not only are we working with all these specialists across these areas, in many if not most of those cases, we have the world's leading biologic that's utilized by these specialists. And the reason why is a combination of the fact that we are providing What we believe is best-in-class, often first-in-class medicines for our commercial team to then explain and deliver to these various specialists. So when you talk about, for example, obesity, we don't want to just compete with just another obesity agent where we're maybe fighting that we might have 1% or 2% more weight loss or something like that. We want to deliver, once again, something that's truly differentiated. and that's what we're striving to do. For example, a weight loss agent that not only causes similar weight loss to all the other weight loss agents but also by a completely different mechanism of action dramatically lowers your lipids and your cardiovascular risk. We also have other approaches that we're combining with our obesity agent to prevent the profound loss of muscle that's caused by many of these obesity agents. and on and on. So if we're entering a space, our goal is not to just compete commercially with the Me Too, but to give our commercial group an agent that really makes a difference for patients, which they can then convey to the specialists that we're already dealing with who have already seen our ability to deliver game-changing, best-in-class medicines to their patients.

Okay, thank you. I think we have time for two more questions, Shannon.

Thank you. Our next question comes from the line of Evan Segerman with BMO Capital Markets. Your line is now open.

Hi, guys. Thank you for taking my question. So the expanded Sanofi Alliance has, I think, four next-gen antibodies focused on type 2 inflammation. What is the unmet need you're trying to solve that Dupixent cannot? And should we think about these programs primarily as franchise expansion, lifecycle protection, or ultimately replacement products? Thank you.

Good questions, Evan. I don't think this is the format where we really want to unveil our strategy. I think the Alliance has some very interesting ideas, and I think you'll hear about them over time. Sorry to put that off, but I do think there's a better format for us to discuss this with Santa Fe.

Okay, let's move to our final question, please, Shannon.

Our last question comes from the line of Alexandria Hammond with Wolf Research. Your line is now open.

Thanks for squeezing me in. So on PNH, the AXIS-1 cohort extension data versus Ultimeris shows some really strong data. If you continue to replicate those efficacy results in the upcoming readout against Solaris, what are your expectations on patients switching in the near term and steady state? I guess, are there any nuances to this patient population? We've heard them being characterized as sticky. Thank you.

Henry, do you want to take that?

Happy to. So, you know, I do think that the early clinical results have been very, very exciting and very compelling. But to the point, we'll have to see additional clinical data differentiation. But certainly, we will look forward to bringing this particular product and indication into the marketplace.

Okay. Thanks, Marion. And thank you to everyone who dialed in for today's call. We apologize to those remaining in the Q&A queue who did not have a chance to ask their questions. As always, the Investor Relations team is available to answer any questions that may remain. Thank you once again, and have a great day.

This concludes today's conference. Thank you for your participation. You may now disconnect.
