Thanks, Ryan, and thanks to everyone for joining today's call. Before we begin, I would like to acknowledge with deep sadness the passing earlier this week of financial industry luminary and long-time Regeneron director, Arthur Art Ryan. Art served on our board for more than two decades and was a trusted advisor whose judgment, integrity, and business insight helped guide the company through many important milestones. Prior to joining Regeneron's board, he built a distinguished career in financial services, including serving as chairman and CEO of Prudential Financial, and previously as president and COO of Chase Manhattan Bank. In addition, Art left an enduring legacy of civic engagement and philanthropy throughout Newark and Essex County, New Jersey. On behalf of everyone at Regeneron, I want to express our gratitude for Art's many contributions and years of service. We joined his family and all who knew him in celebrating his life and legacy. We will miss his wisdom and unparalleled support of Regeneron's mission. Turning now to our business, Regeneron delivered another strong quarter, with total revenues up 17% and non-GAAP earnings per share up 11% compared to the second quarter of 2025, making our second consecutive quarter of double-digit growth on both the top and bottom lines. Dupixen, ILEA HD, and Liptile all set new all-time highs for quarterly net sales and are carrying strong momentum into the second half of the year. Dupixen global net product sales, as reported by Sanofi, were $6 billion, up 38% compared to the second quarter of last year on a constant currency basis. Demand trends, across all approved indications, remained robust and accounted for the majority of the year-over-year growth. We in Sanofi continue to see a long runway for Dupixen growth, driven by further penetration of existing indications, expansion into additional age groups, and international growth opportunities. Beyond Dupixin, we are rapidly advancing a broad portfolio of next-generation programs that we believe can build on the foundation we've established with Dupixin. George will discuss some of our recent progress in this area, including encouraging early clinical data from our long-acting interleukin-13 antibody. Our collaboration with Sanofi spans nearly two decades and has been one of the most successful in the biopharmaceutical industry. Together, we have built a highly productive development and commercialization engine and the continued success of Dupixin in nine FDA-approved indications across specialties ranging from dermatology, pulmonology, gastroenterology, ENT, and allergy highlights the value that this model can create. Given that success, I can report that we have had productive early discussions with Sanofi to identify potential opportunities for further collaboration, including for several of Regenerance to Pixen follow-on programs. Ali HD in the U.S. continued to gain momentum, with net product sales in the second quarter of nearly $600 million, up 52% compared to the prior year. Importantly, this quarter marked the first time ILEA HD net sales exceeded ILEA, highlighting the continued strength of the conversion to a next-generation product. Physician unit demand for ILEA HD in the second quarter increased 24% sequentially, reflecting continued strong update following recent FDA label expansions and growing prescriber appreciation for ILEA-HD's differentiated profile and dosing flexibility. We continue to work towards obtaining approval for yet another product enhancement for ILEA-HD, the ILEA-HD pre-filled syringe. We expect launch of this enhancement to drive even further adoption of ILEA-HD, and we are continuing to work closely with the FDA and multiple contract manufacturers with a goal of approval before the end of the year. All in all, ILEA HD has performed extremely well, and we look forward to continuing to grow this product. Littauer maintained its strong growth trajectory in the second quarter. Global net product sales reached nearly $500 million, up 29% compared to last year on a constant currency basis. Growth was driven by continued strong adoption in its approved non-melanoma skin cancer indications and further penetration in non-small cell lung cancer, where Liptire now captures 20% of new-to-brand prescriptions in the U.S. Beyond its growing patient impact and commercial contribution, Liptire remains the strategic backbone of our ongoing efforts to expand and strengthen our oncology portfolio. Turn it to the rest of the pipeline. I firmly believe that one of Regeneron's core strengths is that we do not rely on any single program or platform. Our pipeline is broad, diversified, and highly productive. And while not every program will succeed, we are confident that it will create many substantial value for patients and shareholders. With approximately 50 active clinical programs and many rapidly advancing preclinical candidates, we have one of the largest R&D portfolios in the entire industry. George will have more details on our pipeline progress in his remarks, but I want to highlight a few important programs where we expect near-term regulatory and clinical milestones. We anticipate multiple milestones for our C5 complement programs, including an FDA decision in November for our new drug application, for simdisoran, and siRNA that targets C5 and generalized myasthenia gravis, which we believe has the potential to offer a differentiated profile for patients living with this serious autoimmune disease. We also continue to make meaningful progress across several longer-term value drivers, including factor XI for coagulation disorders, limoseltumab for multiple myeloma and pre-malignant conditions, and our obesity portfolio, where we expect multiple Phase III study initiations later this year. Now to a few comments on capital allocation, where our framework remains consistent. First and foremost, we believe the highest return opportunities to continue from investing in our own science. At the same time, we remain active in evaluating external opportunities. We're casting a wide net across the universe of business development options, with particular interest in areas where we can leverage, regenerate, differentiated expertise in genetics, antibody engineering, clinical development, manufacturing, and product commercialization. While we remain disciplined on valuation and strategic fit, we believe our financial strength, scientific capabilities, operational infrastructure, and long-term perspective position us well to capitalize on compelling opportunities as they emerge in closing our ability to repeatedly discover develop and deliver important medicines has been a defining strength to regenerate for decades this quarter's performance together with the important milestones ahead reinforces our confidence in the company's long-term outlook we have a thriving commercial business a deep and diverse pipeline, and a talented team committed to improving patients' lives through science. Together, these strengths position us well to continue delivering meaningful innovation for patients and sustainable value for our shareholders.

With that, let me turn the call over to George. Thanks, Len. Today, I'll focus on the key updates from our development pipeline. For a comprehensive summary of our mid- and late-stage pipelines, please refer to the Programs and Clinical Development section of our 10-Q. I'll start with our complement-mediated disease franchise, beginning with Cymdicerine, our C5-SIRNA. Regulatory submissions for Cymdicerine monotherapy in generalized myoceniogravis, or GMG, have been accepted for review by both the FDA and the EMA. The FDA target action date is in November of this year, while a European Commission decision is anticipated in the second half of 2027. If approved, Subdisirin would represent a highly differentiated treatment option in GMG and be the first sRNA approved for this disease. We believe some discerin's efficacy, safety, and convenient four-times-per-year subcutaneous dosing profile highly differentiated from C5 antibodies and other modalities approved for GMG. For some discerin, in combination with Pozelmat, our C5 antibody, we continue to expect registrational data in paroxysmal nocturnal hemoglobinuria, or PNH, in the fourth quarter of this year. Our phase three leading cohort that compared this combination with rabilizumab, an FDA-approved antibody to C5 for the treatment of PNH, suggested that our combination could provide a more convenient monthly subcutaneous regimen that could also improve disease control based on LDL meshes and support our hypothesis that complete complement blockade in this disease is required to sustain disease control. As a reminder, the registrational study is evaluating noninferiority of our C5 combination versus eculizumab, the other C5 antibody that is FDA-approved for the treatment of PNH, using co-primary endpoints of intravascular hemolysis control as well as transfusion avoidance. In ophthalmology, our C5 approach in geographic atrophy, or GA, remains on track to read out 26-week data from our exploratory cohort in the fourth quarter of 2026, which will help inform our pivotal strategy. As a reminder, we are evaluating systemic administration of syndicerine with or without pozelimab with the goal of slowing the rate of GA lesion growth and associated declines in visual acuity while avoiding the ocular safety issues that have been observed with certain FDA-approved therapies. We are also evaluating intravitreal in GA to provide optionality and are actively developing co-formulations of this with other agents, such as Aflibrocept, to address comorbid retinal disease settings. In immunology and inflammation, to follow on onto Pixin's success, we continue to advance a series of next-generation, fully human-animized and biospecifics designed to build onto Pixin by extending duration, enhancing target coverage, and potentially improving efficacy. We have enrolled initial healthy subjects in our first in-human trial for a long-acting IL-13 antibody and expect to begin dosing patients with atopic dermatitis later this quarter with plans to execute an expedited path to starting registration-enabling studies, potentially by the end of next year or early 2028. Our initial clinical data indicate that this antibody has a prolonged half-life that has the potential to extend the dosing interval well beyond those achieved with currently approved products in this category. First and human studies of our other next-generation long-acting antibodies are planned, with next-generation Dupixin, or Soupy Doopy, expected to be clinic-ready by early 2027, and additional candidates, including our IL-4, IL-13, 5-specific, next year. Briefly, on to oncology. Uvamadamab, or MUC16 by C3 bispecific, continues to demonstrate promising monotherapy activity in low-grade serious ovarian cancer, a subset of advanced ovarian cancers, and we plan to present detailed data in this setting at a medical meeting this fall. We also continue to advance pivotal studies for linozific, or BCMA by C3 bispecific, in multiple myeloma and premalignant conditions, including a newly initiated pivotal study in high-risk smoldering multiple myeloma. We expect results next year from the Linker MM3 study, our confirmatory trial of the nocific monotherapy versus standard of care, and patients have received at least one but no more than four lines of therapy. In 2028, we expect minimal residual disease or MRD negativity results from our first-line study in transplant ineligible myeloma patients, as well as our linozific carfilzomib combination study in myeloma patients who have received one or more prior line therapy. At the American Society of Clinical Oncology, or the ASCO meeting, we presented first results from the Phase I-II linker AL2 trial of linozific monotherapy in patients with second-line plus systemic light chain or AL amyloidosis. Normalization of free light chain occurred by day 15 across all doses, and 100% of patients achieved a hematologic complete response at the highest dose test. The majority of patients with renal or cardiac involvement demonstrated improvement in organ function despite short follow-up. The phase 2 portion of the study, which has registrational intent, is now ongoing. A phase 3 study in first-line light chain amyloidosis It's planned to start early next year. Moving to anticoagulation, we are on track to initiate the remaining Phase III studies from our comprehensive Factor XI program this year, featuring Synvacibart, our catalytic antibody formerly known as REACH-N7508, and Amrezibart, our A2 antibody formerly known as REACH-N9933. Federal results from our studies in venous thromboembolism, or VTE, prevention, following total knee replacement surgery are expected in the first half of 2027. Also in 2027, we anticipate results from the Phase II ROXI-ATLAS study, which evaluates both Factor 11 antibodies against apixaban in stroke prevention in patients with atrial fibrillation, or SPAP, which is expected to provide us with important insight into bleeding risks after three months of observation. We have also begun enrolling patients in our Phase III SPAF trial, ROXI-INCLINE, that will evaluate both of our antibodies against placebo in patients who are not candidates for conventional anticoagulant therapy. We remain excited about our program and favor antibodies as opposed to a small-molecule approach as we believe antibodies enable greater and more specific inhibition of Factor XI, leading to improved antithrombotic activity without increased bleeding risk or other off-target safety issues. Turning to obesity, oloreptotide, our dual GLP-GIF receptor agonist in license from HANSO continues to advance. Data from Hanzo's Phase III study of oloreptide in Chinese patients with obesity, which top lined in March, would be presented as a late breaker at the European Society for the Study of Diabetes Conference, or EASD, in October. Acknowledging the inherent limitations of cross-trial comparisons, oloreptide generated weight loss that was comparable to the weight loss observed in a similar study of trisepatide in China, while demonstrating a favorable gastrointestinal tolerability profile, including meaning meaningfully lower rates of diarrhea, nausea, and vomit. Remain on track to commence Phase III studies later this year in patients with obesity as well as patients with obesity and type 2 diabetes. In addition to the alitorepatide monotherapy program, we also continue to advance our combination of OLA and Pralut, our PCSK9 antibody, to address patients with obesity or type 2 diabetes that have comorbid hypercholesterolemia. Also at EASD, we will present 52-week results from the COURAGE study, including accompanying MRI findings in a subset of patients. Adding tribo-grubab to semaglutide did not drive additional weight loss, but did show encouraging skeletal muscle mass preservation versus semaglutide alone. These findings reinforce our belief that preventing muscle mass loss may become increasingly important as obesity treatment involves, particularly in older patients with sarcopenic obesity. In rare disease, we expect an FDA decision in August for gartosamab, or an active in aid blocking the antibody, in fibrodysplasia osteoporosis progressiva, or FOP. If approved, gartosamab would be the first treatment shown to reduce the number of new abnormal bone formation lesions, as well as clinician-assessed flare-ups in FOP patients. From our earlier stage pipeline, we're planning to present at medical meetings this fall some promising clinical data from our pipeline of SIRNAs for metabolic dysfunction-associated steahepatitis, or MASH, and for our NPR1 antagonist antibody, Belogservard, for the treatment of postural arthostatic tachycardia syndrome, or POTS. Finally, we continue to work with the U.S. government and international health organization to deliver potential new treatments for the devastating recent Ebola virus epidemic that is driving the current outbreak in the Democratic Republic of the Congo. Regeneron-developed antibodies are now being tested in non-human primates, with early data showing they can prevent mortality when it's administered even after clinical symptoms have already appeared. We are talking with the international health organizations to see whether we will be able to once again help with the current Ebola outbreak as we have in previous outbreaks. In summary, we remain focused on rapidly advancing our broad, diverse pipeline, which we firmly believe has the potential to change the practice of medicine across many diseases with high unmet needs. And with that, I'll turn it over to Mary.

Thanks, George. Our second quarter results reflect strong commercial execution across our portfolio, delivering meaningful growth from our market-leading brands in multiple therapeutic categories. Starting with our retinal franchise, in the second quarter, ILEA HD and ILEA delivered just over $1 billion in combined U.S. net sales, up 7% quarter over quarter. We also achieved an important milestone in the second quarter, with more than 100 million doses of ILEA HD and ILEA administered to patients. since ILEA's launch in 2011. Second quarter, ILEA HD net sales in the U.S. were $596 million, representing a 52% year-over-year increase and 27% growth quarter-over-quarter. These results reflect strong physician demand, which grew 24% from the prior quarter. ILEA HD has the broadest label and greatest dosing flexibility of any anti-VEG of medicine, following last year's label enhancements to include retinal vein occlusion and additional dosing options that range from every four weeks through to every 20 weeks. ILEA HD now comprises approximately 60% of U.S. franchise net sales compared to 34% in the second quarter of last year. Within the innovative branded category, ILEA HD and ILEA captured 57% share in the second and quarter. And ILEA HD was the only innovative brand that achieved quarter-over-quarter share growth. Physicians increasingly recognize ILEA HD for its efficacy, safety, and durability profile. Initial uptake of ILEA HD in RVO has been strong, driven by its differentiated label and clinical data. ILEA HD is the only product that offers every eight-week dosing in this indication and was the only product to demonstrate numerical improvement in visual acuity in clinical studies compared to ILEA, the prior gold standard in RVO. ILEA U.S. net sales in the second quarter were $412 million, representing a 45% year-over-year decline and a 13% decline quarter-over-quarter, primarily driven by ongoing conversion to ILEA HD and competitive dynamics. Looking to the second half of 2026 for ILEA, we expect sequential quarterly demand declines in the low to mid-teens due to the factors mentioned, as well as additional competition primarily from multiple Flibercept 2-milligram biosimilar launches. With an ILEA-HD label that now includes wet AMD, DME, DR, and RVO, as well as the broadest dosing interval in the category, retina specialists increasingly recognize ILEA-HD as the next standard of care in the anti-VEGF category. We expect this will drive sequential demand for ILEE-HD in the low to mid-teens in the third and fourth quarters of 2026. Turning to Depixin, which continues to deliver significant benefit to patients globally, with more than 1.5 million patients actively treated worldwide, Depixin has had a tremendous impact across its nine approved indications, and it's the number one biologic medicine prescribed by dermatologists, hominologists, allergists, and EMTs. Second quarter net sales were $6 billion, reflecting 38% growth on a constant currency basis. In the U.S., sales grew 42% year-over-year to $4.6 billion, primarily driven by continued growth across our blockbuster indications and uptake in recent launches. In addition, as reported by Sanofi this morning, a favorable gross-to-net adjustment also boosted U.S. net sales in the quarter. Depixen continues to drive strong growth across blockbuster indications, including atopic dermatitis, asthma, nasal polyps, and a synophilic esophagitis, supported by its clinical efficacy and safety profile. Uptake is also growing on our new indications of COPD, chronic spontaneous urticaria, bollus pemphigoid, and allergic fungal rhinocitis. With significant opportunity to improve the lives of even more patients, Depixin is well-positioned for sustained growth over the near and long term across approved indications. In the second half of the year, we expect year over year global net sales growth to remain strong, but to moderate relative to the first half of 2026 as we annualize recent indication launches and face stronger prior year comparisons. Turning to Liptayo, which delivered worldwide net sales of 489 million, up 29% year over year on a concurrency basis. In the U.S., sales grew 38% year-over-year to $343 million with growth across both non-melanoma skin cancers and non-small cell lung cancer. The recent launch in adjuvant continuous gram cell carcinoma has generated positive feedback on this paradigm-changing treatment and has been accompanied by increasing use across all approved CSCC settings. In first line non-small cell lung cancer, Liptio is now firmly established as the second most prescribed immunotherapy treatment in the U.S., where Liptio's share of new patient starts has doubled since early 2025 to 20% as physicians increasingly recognize its strong clinical profile. We expect continued growth for Liptio in the second half of 2026 as we strive to gain incremental share in lung cancer and drive uptake across all approved stages of CSCC. On to LinoZific, which is now in its third full quarter on the market, physician feedback in this late-line treatment setting is positive based on LinoZific's differentiated efficacy and safety profile, lower hospitalization requirements, and community dosing. Despite its strong profile, we expect LinoZific growth to remain modest in this small late-line setting as we work to advance into earlier lines of therapy. Turning to rare disease, where Regeneron is expanding our portfolio of life-changing medicines for patients with significant unmet medical need. Our homozygous familial hypercholesterolemia medicine, Eftiza, delivered net sales of $53 million in the second quarter, representing 29% year-over-year growth. I'm also delighted to inform you that first patients have been dosed with Otarmini, the first and only gene therapy for children born with genetic hearing loss, and our early launch efforts continue. We are looking forward to adding geratosumab to our rare disease portfolio with a potential FDA approval in August for FOP. FOP is a serious life-threatening disease where geratosumab would be the first treatment shown to reduce the number of new abnormal bone formation lesions as well as clinician-assessed flare-ups in FOP patients. We are also excited about the potential FDA approval of sendicerin and generalized miocene Gravis later this year. We see significant opportunity in a large and growing category based on some disciplines clinical profile demonstrated in this pivotal study, including rapid, deep, and sustained clinical benefit, favorable safety profile, and convenient quarterly subcutaneous dosing. In closing, our second quarter results reflect focused commercial execution across therapeutic areas. We continue to drive growth for our inline brands and are preparing for upcoming launches. We remain well-positioned to deliver meaningful benefit to patients worldwide across many different diseases. And with that, I'll turn the call to Chris.

Thank you, Marion. My comments today for Regeneron's financial results and outlook will be on a non-GAAP basis unless otherwise noted. Regeneron delivered a strong second quarter highlighted by continued momentum across our key growth drivers and disciplined execution across the business. Second quarter total revenue increased 17% from the prior year to $4.3 billion, driven by higher Sanofi collaboration revenue, reflecting the continued strength of Dupixen, as well as strong growth for ILEA HD in the U.S. and Liptio globally. Second quarter diluted net income per share grew 11% to $14.29 on net income of $1.5 billion. This included a $0.99 negative impact from acquired in-process research and development expense, reflecting upfront and opt-in payments associated with collaboration and licensing agreements. Beginning with the Sanofi collaboration, second quarter total Sanofi collaboration revenue reached an all-time high of $2.2 billion, of which $2 billion related to our share of collaboration profits. Regeneron's share of profits grew 59% versus the prior year, driven by de-pixing growth and improving collaboration margins. We've now fully repaid the Sanofi development balance, which was approximately $3.1 billion when the Sanofi antibody collaboration agreement was amended as part of the 2022 Liptio transaction. action. That amendment accelerated repayment of the balance, which further reduced our share of collaboration profits as it was paid down. The repayment lowered our reported Sanofi collaboration revenue by approximately $930 million in 2025 and $530 million in the first half of this year. Given full repayment of the Sanofi development balance, starting in the third quarter, we expect Saniki collaboration revenue to step up as we record our full share of collaboration profits. Moving to buyer, second quarter net sales of ILEA 8MIG and ILEA outside the U.S. were $667 million, inclusive of $366 million of ILEA 8MIG sales. Total buyer collaboration revenue was $276 million, of which $227 million related to our share of net profits outside the U.S. Other revenue in the second quarter increased 5% to $193 million, of which royalty income from Alaris combined with our share of profits from Archelis totaled $157 million, an increase of 44% versus the prior year. Now to our operating expenses. R&D expense was one and a half billion in the second quarter, reflecting continued investment to support Regeneron's innovative pipeline, which has approximately 50 product candidates, including mid- and late-stage programs across hemonc, anticoagulation, and complement-mediated diseases. Second quarter SG&A was 574 million, reflecting investments to support our commercial portfolio, including continued growth of ILEA HD and Liptio as well as ongoing launch activities across our broader product portfolio. Non-gap gross margin on net product sales was 87 percent in the second quarter. Our gap gross margin was 78 percent which similar to the first quarter was negatively impacted by unabsorbed manufacturing costs related to the temporary interruption in bulk manufacturing production at our Limerick Ireland facility. Production at this facility resumed to normal levels as of the end of the second quarter. Regeneron generated $1.4 billion of free cash flow through the first half of 2026 and ended the second quarter with $15.1 billion of cash and marketable securities net of debt. During the first half of the year, we deployed approximately $2.5 billion to share repurchases, business development, and dividends. Within that, we repurchased $1.2 billion of our shares in the second quarter alone, bringing total repurchases to approximately $2 billion for the first half, resulting in a net reduction of 2.4 million shares outstanding since the end of 2025. As of June 30th, we had $2.5 billion of share repurchase authorization remaining, and we continue to be opportunistic buyers of our stock. Finally, we made modest refinements to our 2026 financial guidance as we enter the second half of the year. A full summary of our guidance can be found in our earnings press release published earlier this morning. In conclusion, Regeneron's strong second quarter results position us well to continue investing in our differentiated pipeline, delivering important medicines to patients, and prudently deploying capital to drive long-term value for shareholders. With that, I'll pass the call back to Ryan.

Thank you, Chris. This concludes our prepared remarks. We will now open 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. Michelle, can we go to our first question, please?

Our first question comes from Chris Raymond with Raymond James. Your line is open.

Hey, thanks for taking that question. Just on cash management, so you guys have about $18 billion on hand now with the Sanofi obligations sort of rolling off. I guess it seems that that will be accelerating pretty meaningfully. Hearing what you guys have said about R&D and share repurchases and other uses of cash, even with pretty robust investment, that outlook's pretty sizable. Len, I'm wondering if you could maybe square that dynamic with some of the aversion to M&A that you've expressed in the past as a primary use of cash. Thanks.

Thanks for the question. I don't think I expressed an aversion to M&A. I think I expressed an aversion to overpaying in M&A settings. And we have been involved in many of these interested transactions, and we have seen people pay far more than we think the value would justify. We deploy a lot of our R&D money, and I think we'll talk more about that later in the year, and Chris gives some guidelines. But if you look at what we spend on R&D, both internally and externally, we're really kind of in line with what other people spend but we tilt more towards the internal R&D we are not allergic to any external opportunity we look at them all but we are pretty disciplined in trying to create value with these transactions so no aversion whatsoever we can do small we can do large but we want them to make sense and make money for our shareholders over the long term.

Thanks, Len. Michelle, let's go to the next question, please.

Thank you. Our next question comes from Chris Scott with J.P. Morgan. Your line is open.

Hey, this is Taylor Hanley on for Chris Scott from J.P. Morgan. Thanks for taking our question. We were just wondering, given some of the recent updates in the broader I&I space, can you talk a bit more about your latest thoughts on expanding the Sanofi collaboration to include additional assets, and then also what steps you could take to accelerate the development of those assets. Thank you.

Right, thanks for the question. I think as you heard from Sanofi today, they talked about the productivity of our alliance, and we agree with that, that this has been perhaps one of the, if not the most productive alliance in the history of our industry, with Depixen driving remarkable returns for both Sanofi and Regeneron. We do have some follow-on opportunities to Depixen, as George mentioned in his talk, including our IL-13 long-acting antibody, which we now confirmed with the very early PK data, Soupy Doopy, and we have several others that are related to the Depixen portfolio. We have had productive early discussions. Beilin, the new CEO, and I have talked multiple times. We are looking to see what might make sense and what kind of transaction might make sense for the two companies to get together on further assets where some of those assets might be best-owned in a depiction portfolio. We'll keep you posted on those discussions as they progress.

When you asked about development and expediting it, we should just remind you that we have led the most innovative development program probably in the history of the industry in terms of, with Dupixen, getting it approved for nine different indications, including many of them, the first approved biologic in many of these indications. Obviously, we know this field. We created this field better than anyone else. And just as we've been very innovative with the first in class to Bixen, you can imagine it will be just as, if not more innovative going forward. Thanks, Len and George. Michelle, next question, please.

Our next question comes from Tyler Van Buren with TD Cowan. Your line is open.

Good morning. Congratulations on the tremendous quarterly performance. So can you provide additional details on the ongoing ILEA HD pre-filled syringe review with hopeful approval by year-end now? And when you say working with multiple contract manufacturers, does that mean there is now a third CMO in the mix? And if so, why did you feel they need to add another, or is it still just the two, and is the second one most likely to receive approval by the end of the year? Thank you.

Yeah, thanks, Tyler. Look, a lot of things have been changing at the FDA. People have been changing. Leadership has changed. We had thought that we would get some action, perhaps an approval by the end of the second quarter. That obviously didn't happen, but we have now had renewed discussions. We are looking at leaving no stone unturned, multiple, and that means more than two are in the mix. We could always use backups if we succeed on one, three, one and two, two and three, or three and so forth. But we're doing everything we can. We've had some good conversations recently. We know what the path is. We could see this ending by the end of the year or sooner.

Cheryl, next question, please.

Our next question comes from Corey Kasimov with Evercore ISI. Your line is open.

Before you begin, I neglected to point out, if you think about ILEA HD and how it's progressed, we had a great product. The product itself really made a difference to patients in terms of durability. The doctors really appreciated it. But we felt that we could bring on additional enhancements to really make the product even more attractive to patients and the doctors. Those enhancements included getting the Q4 monthly indication in the label. It included getting the RVO indication with a favorable, and the only one with a favorable interval, and getting the long-term durability intervals in the label. Those three enhancements have really driven ILEA HD, and it's really the only product in the branded space that has had this remarkable growth recently. We think that can continue, but we do believe if we can add another enhancement, it would go even set another leg up. But everybody should understand that the product is doing great. Just look at the numbers, look at the growth, look at how the other products in the space are doing. It's really doing very, very well.

Let's move to Josh. Are you still on the line from Evercore?

Still here. From the market research you've done in Mycena Gravis, what percent of the market is currently served by IV C5 therapies, and do you expect a robust switch market to develop when some discerin reaches the market before the end of the year?

Oh, you're welcome. We very much look forward to the potential approval of some discerin and bringing our product into the marketplace for GMG patients. Very important market, certainly therapies in the market today, but we do believe our clinical profile, our safety profile, convenience of dosing will be very meaningful. We have experts working on the commercialization launch strategy. We know the market well through them. We've had an amazing ability to attract talent to the organization for this launch. Specifics on launch strategy, market size opportunity will hold until later times. But just to assure everybody that we look forward to the launch and we're preparing for it actively. And obviously, as we mentioned today, potential approval from FDA in November.

Yeah, just to amplify a tiny bit on what Marion said, to address some part of your question. Look, the switch population is obvious what some might say in the business, one of the lower hanging fruits in this space. But we're not going to only focus on that, because if you look at the FCRN approach, our data in terms of convenience potentially being given very infrequently to be able to have a continuous effect on myosteagravice patients in their ability to function. I think this can compete in all segments, but of course there are some easier versus harder parts of the market.

Thanks, Marion and Lynn. Let's move to the next question, please, Michelle.

Our next question comes from Salveen Richter with Goldman Sachs. Your line is open.

Good morning. Thanks for taking my question. You'll be presenting data from one of your CERNA programs in MASH this year. Could you just speak to the expected differentiation of this asset versus approved targeted agents, such as ResDifra, and then maybe put the commercial opportunity in context for us, especially with the uptake of GLIPS in this category as well.

Right. All other agents in this field are not really directly addressing the mechanism of MASH itself. They're working indirectly by decrease, for example, food intake through the GLIPS and other mechanisms. What I want to remind you is due to the investment we made in the Regeneron Genetic Center, we have actually redefined the field. We invented, we discovered actual genetic mechanisms that are protective for the actual basis of this disease. And the genetics would suggest that if you could come up with a medicine that could mimic the genetics like we've done in other areas, then we could directly impact the actual mechanism of this disease and perhaps reverse it more quickly and more deeply than other indirect approaches, which are not directly working on the mechanism itself, but working indirectly, as I said, by decreasing food intake and so forth. So these would be results using the first agents that are directly addressing the methods of action of this disease as defined genetically so we will be very excited to see based on this potential how these agents will have performed in these clinical studies okay thanks George exciting data to come next question please Michelle our next question comes from Alexandria Hammond with Wolf your line is open hey guys thanks for taking a question so on On both DCEMD and PNH, we're expecting that readout later this year, so if you kind of help us think about the incremental data points beyond LDH control, maybe transfusion avoidance

that you need to see to kind of support a best-in-class label claim, and assuming a clean readout, what does the regulatory and commercial path look like from here and timeline? Thank you.

Well, we strongly believe that improved control of intravascular homolytops is the most relevant and validated endpoint because it directly reflects the T5 mechanism of action. And it's directly related to preventing what are the most devastating consequences of these disease, which is thrombosis and clotting and so forth. And that is what we're really looking for. We think that that would most strongly demonstrate whether this product is really differentiated and perhaps superior to existing therapies in addition to providing a much more convenient dosing regimen. So that's what we're really focused on here. We think that that is what everybody should focus on because it directly addresses the C5 mechanisms of action and it's related to what are the devastating consequences of this disease.

Thank you, George. Let's go to the next question.

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

Hi, good morning. Thanks for taking my question. I wanted to get your thoughts on SEMD Saran, on how you're thinking about the launch trajectory in GMG. So you would be entering a market that has quite a few options. So can you just give us your thoughts about what you think doctors in particular could respond to as a differentiating factor relative to, you know, let's say the market leader, which is Discard right now.

Thanks.

So certainly as we launch into the market, we study it carefully in the competitive dynamic. As I mentioned with some Disrin, we're very excited about the potential launch in November in the U.S. marketplace, certainly working towards that. In terms of the overall uptake, it's probably early to predict, but I would point to some of the characteristics of some Disrin that are really exciting, not only to Regeneron, but to the key opinion leaders and physicians who've been involved in the clinical trials, and that is the efficacy, the safety, the convenience of dosing, and those elements certainly have the opportunity to create differentiation that will be meaningful in that market.

Yeah, just to add that from a clinical point of view, I don't feel it's optimal to chase symptoms. It's much better to have a steady improvement where you're not cycling on and off. And some of the, clearly in the FCRNs, you see this cycling, even though you can even give repeat cycles now, you still are seeing evidence of loss of control. And we think that, you know, the unpredictable nature of all that compared to giving something every quarter by a simple injection is really going to be changing the practice and the way patients think about it. Convenience does matter, but we know that.

Yeah, as Len said, it's important that a significant proportion of the FCRN-treated patients do lose efficacy over time and have to be switched to another therapy. We think that we have obviously an optimal option for patients and physicians to consider. We think that we have the best efficacy across studies shown in the field, but as Len said, we have consistent efficacy over time. we have convenience but we should also not dismiss that one of the concerns with all the treatments here is the impact on complete complementing mission and also immunosuppression with FCRNs and we have to remind you and this is something that we have to remain to demonstrate but what we have demonstrated which is very clear and for the first time is that we are achieving best-in-class efficacy in cross-study comparisons while doing this using this sRNA approach without complete complement inhibition, which is really stunning. And that may, over time, represent another benefit to patients that we'll have to demonstrate, probably using real-world evidence and so forth over time. But I think this is a very, very exciting and very differentiated profile that There's the opportunity not only to capture by switch a lot of the C5 class, but also all the patients who, over time, begin to lose efficacy using the FCRN approaches. Thank you. Next question, please, Michelle.

Our next question comes from Evan Siegerman with BMO Capital Markets. Your line is open.

Hi, guys. Thank you so much for taking my question. And I want to follow up on your partnership with Sanofi. You know, it's been a very successful partnership for Dupixent. As you think about the next phase of the relationship, what are the key elements you want to preserve from the original collaboration, and where do you see opportunities to improve the structure going forward? Thank you.

It's a very astute question, Evan. I'll answer in more general terms than will satisfy you because these are ongoing negotiations. But what we want to do is capture the joint learned capabilities and experience in developing and commercializing to fix it. And those learnings are substantial. And together, if we're able to reach an agreement, they would, I think, drive success of these follow-on products. I think as Baylin may have mentioned in her Q&A today, we need to make some adjustments. When we were a first partner with Sanofi, George probably remembers Baylin either, but it was got to be a couple of decades ago. We were quite a different company. And so the rules of the game were a little bit different. And so we have to, I think, get together and be open-minded, and I think Berlin is, to have a relationship that reflects where the companies are now. So I'm cautiously optimistic that we can get there.

But I think importantly, the companies have complementary as well as overlapping strength and so forth. And I think that the proposed deal opportunities will take advantage of both the complementary but also overlapping strengths of both companies.

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

Our next question comes from Gregory Renza with Truist Securities. Your line is open.

Great. Good morning, guys. Congrats on a nice quarter. Thanks for taking my question. And I just wanted to follow up on the obesity programs and certainly that path. You've commented certainly on this evolving quick landscape here. Just given the maturity landscape, what is the realistic timeline for the GLIP-GIPR plus probably one combination? And how should we be thinking about that potential and differentiation to carve enough share here? Thank you very much.

Well, as we've announced, we're going to be initiating the Phase 3 program over the next few months, and we're continuing to advance the combination, the way that we're looking at it, and I think the way we've termed it is, everybody's trying to compete by getting a few more percentage points of weight loss and so forth, whereas what we're trying to do is provide a fundamentally substantially different profile. So imagine if somebody had invented a glib that could also lower your bad cholesterol by 50% to 60%, and substantially, in addition, further you reduce your risk of cardiovascular disease. Well, that's what we're offering, and our program is advancing quickly in this area. In addition, providing co-treatments that counter some of the negative aspects of GLP-induced weight loss, such as muscle loss, would be, once again, a fundamentally different profile. and we're moving those programs along and we'll be releasing more data from those programs and so forth. So we think it's very different to not just be going after a few more points of weight loss, but substantially enhancing the profile that you get along with it, whether you're addressing a related comorbidity that many of these patients also suffer from, which is cardiovascular disease, or a side effect that causes and is being recognized as causing increasing problems, especially for sarcopenic patients, that is patients who are already starting with low muscle mass. Those are the sort of things that we're actually going for. But we also, as we discussed, at least in cross-study comparisons, the GLP that we're working on might have indeed favorable profile on its own as well. I should also remind you that we have a very additional deep and slightly earlier stage pipeline using many other approaches as well that we're very excited about, but we don't have time to discuss right now.

Okay. Thank you. We have time for two more questions, please, Michelle.

Our next question comes from Carter Gold with Cantor. Your line is open.

Great. Good morning. Thanks for taking the question. I think this problem probably falls on George here. On the back of the Cianlamap setbacks and coast in progress, which has been relatively paced, I was wondering if you kind of used that as an opportunity to step back, reassess your solid tumor portfolio. It clearly was less of a point of focus on the call today and maybe just how you see that going forward and if that's still going know, warrant the same sort of spend and attention and effort that's had in the past couple of years?

Yeah, well, obviously, cancer is a challenge. I mean, you know, the United States put out a war on cancer in the 1960s. I don't know if you realize it, but back in the 1960s, they did a survey, and 90 percent of the U.S. population thought that based on the war of cancer would be cured. 90% of the US population thought cancer would be cured by the year 2000. Clearly, we celebrate incremental advances in the field. I mean, getting a few more months here and there. We think that, obviously, Fianna Lab demonstrated that it was an active agent. Numerically, it did add about five months in PFS, and as you saw, we just missed on our primary endpoint. point. We have a lot of programs, many programs, both in solid and liquid tumors. We continue to be very excited about them and moving them forward. And if anything, we are going to continue to advance and continue to take more shots in many different ways, both in monotherapies and combinations using a lot of our unique and first-in-class agents against this very tough and devastating disease and we hope to be delivering successes going forward but as we all know it's a challenging field but we need progress and we're not going to stop focusing on it.

Okay last question please Michelle.

Our last question comes from Jeff Meacham with Citi. Your line is open.

Great. Thanks, guys, for the question. Just overall, maybe a bigger picture on ophthalmology. Just trying to get a sense for you guys' strategy, obviously beyond VEGF. How do you think about, you know, kind of the investments, the strategy, looking at, you know, complement and glaucoma and others? Is this like a vertical that, you know, we should expect you guys to add a lot of resources to in terms of, you know, R&D investments? or is it really, you know, HEMONC is the primary focus in INI?

Yeah, we have a huge, huge investment belief in our ophthalmology portfolio. As I like to put it, we're hoping to deliver the sort of successes and differentiated advances that we did with ILEA for AMD and all those associated diseases and bring those elsewhere. where, as I like saying, we want to deliver the ILEA for glaucoma, we want to deliver the ILEA for thyroid eye disease, and as you just said, for geographic atrophy and related diseases, we want to deliver those sorts of excess successes. We think that there's still so much opportunity in all of these areas, but since we're furthest advanced right now in geographic atrophy, we know the field needs safer agents, the The field needs longer-acting agents. The field needs to address the fact that many of these patients suffer from comorbid diseases. There are many patients with GA who also have wet AMD who need to be simultaneously treated with multiple injections to try to control both sides of the disease. And obviously, we know the devastating consequences that are possible with some of the current complement treatments for this disease. So we think that there's many, many, many ways that we can really help patients out here because there is a crying need, just like, as I said, just like in cancer, we have so much unmet need, and we're going to continue to focus on that. We're going to continue to focus on I. We're going to continue to focus in all the many areas in I and I, and that's as Len started the show today. He highlighted the thing that distinguishes us is we don't take one shot. We don't focus on one thing. Because many times the one thing doesn't work out. But when you look over the years at the many shots that we've taken, so many of them have delivered so much benefit to so many patients and have literally changed the practice of medicine. That's what we continue to do. We don't just focus on eye or on one disease in eye. We don't just focus on one indication in immunology. We don't just focus on one setting in cancer. We focus on everything, and that's why we have the deepest and broadest and, I think, most exciting pipeline in the history of the industry.

Thank you, George, and thanks to everyone who dialed in for your interest in Regeneron. We apologize to those who remain in the Q&A queue who we did not have a chance to hear from today. As always, the investor relations team is available to answer any remaining questions that you may have. Thank you once again, and have a great day.

Thank you for your participation. this does include the call, you may now disconnect.
