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

Thank you, Ryan, and thanks to everyone for joining today's call. Regeneron had a strong quarter, highlighted by 11% revenue growth and 8% non-GAAP earnings growth, along with continued investments and advances across our broad pipeline. For my remarks today, I'd like to review some of our key performance drivers and then briefly discuss near-term pipeline opportunities. After my remarks, George will provide further updates on our pipeline. Marion will then review our commercial performance. And finally, Chris will detail our quarterly financial results. Third quarter, 2024 total revenues grew 11% to $3.72 billion, primarily driven by higher Sanofi collaboration revenues reflecting the continued strong performance of Dupixent, continued growth for Libtayo, and growth for combined EYLEA HD and EYLEA in the United States. Dupixent had another strong quarter with global revenues of 24% on a constant currency basis to $3.8 billion. With this latest quarterly result, global Dupixent revenues are annualizing at over $15 billion, with over 1 million patients currently on treatment around the world across seven approved indications in patients as young as six months. In September, the FDA and Chinese regulators both approved Dupixent for patients with uncontrolled COPD and an eosinophilic phenotype. These approvals, along with the approval in Europe in June, enabled Dupixent to address several hundred thousand patients that are currently uncontrolled on maximal inhaled triple therapy. As Marion will discuss, early launch indicators have been positive with strong physician interest and initial favorable US payer coverage decisions. As the only approved biologic for COPD, we anticipate these ongoing launches will represent a meaningful driver for Dupixent's continued growth in 2025 and beyond. Net product sales for EYLEA HD and EYLEA combined were $1.54 billion, up 3% compared to the prior year. EYLEA HD generated $392 million in its full quarter on the US Market. EYLEA HD and EYLEA maintained anti-VEGF category leadership with a combined share of approximately 44% compared to 45% in the second quarter of 2024. As Marion will discuss, we have focused on increasing EYLEA HD share, while preserving share for EYLEA in an increasingly competitive category, including a near-term biosimilar aflibercept 2-milligram launch and the recent launch of a branded pre-filled syringe. The EYLEA HD clinical profile continues to look differentiated relative to EYLEA and other anti-VEGF products. As George will soon detail, results from the recently reported photon extension study in DME further underscore EYLEA HD's unprecedented durability while achieving vision gains and a safety profile typically seen with EYLEA. Moving to our pipeline, we're excited about several upcoming readouts later this year and in 2025 to further inform programs that could support significant long-term growth opportunities. By year-end, we expect to share interim Phase II lung cancer data for the combination of fianlimab, our LAG-3 antibody plus Libtayo, as well as proof-of-concept data for our Factor XI antibodies in thrombosis, both of which will inform our Phase III plans. Looking ahead to 2025, we expect to read out the results of our pivotal AERIFY studies for itepekimab, our IL-33 antibody in former smokers with COPD. We will also learn more about the potential opportunity to improve the quality of weight loss in obese patients on semaglutide by blocking myostatin and/or Activin A. Pivotal data for the fianlimab-Libtayo combination in first-line metastatic melanoma are also anticipated, which could support regulatory filings in this setting. In addition, we expect to provide periodic updates on our novel treatment approach for reversing severe food allergies, involving linvoseltamab, our BCMA by CD3 bispecific, and Dupixent. In closing, our pipeline continues to generate innovative and differentiated opportunities and now has approximately 40 programs in clinical development spanning many distinct therapeutic areas. We view our pipeline as the key to driving medium and long-term shareholder value and our antibody platform technologies and the Regeneron Genetics-centered database of over 2.5 million sequenced exomes linked to de-identified health records is expected to provide an enduring competitive advantage that we will continue to invest in. With that, I'll now turn the call over to George.

Thanks, Leonard. I'll start with EYLEA HD and the data from the Photon extension study in diabetic macular edema that were recently presented at the American Academy of Ophthalmology Annual Meeting. In addition to demonstrating that the vision gains and anatomic improvements with EYLEA HD over two years could be sustained over a third year of treatment, the results of the extension study provided the first data for patients who switched from EYLEA to EYLEA HD. For these switch patients who were dosed for 88 weeks with EYLEA every eight weeks following five initial loading doses, retinal fluid re-accumulation was substantially slower after a single EYLEA HD injection at week 96 compared to these patients' previous rate of fluid accumulation with our EYLEA 2 milligram. In addition, after one year of EYLEA HD treatment, 83% of these switch patients had a last assigned dosing interval of at least 12 weeks. Importantly, mean visual and anatomic achievement improvements achieved with EYLEA were sustained following the switch to longer dosing intervals with EYLEA HD. For Photon, patients assigned to EYLEA HD treatment groups at baseline, visual gains and anatomic improvements achieved in the first two years were all sustained in three years, but many of these patients were able to meaningfully extend the dosing interval. At the end of three years of treatment, nearly half were assigned the final dosing interval of at least 20 weeks. In summary, EYLEA HD achieved consistently longer dosing intervals, as well as notably slower fluid re-accumulation compared to EYLEA, a first for the category. When all other anti-VEGF agents were compared to EYLEA in head-to-head studies, these agents did not demonstrate slow fluid re-accumulation. The safety profile of EYLEA HD has continued to be similar to EYLEA through three years and remains generally consistent with the known safety profile of EYLEA HD in its pivotal trials. Altogether, these data support our belief that EYLEA HD has a best-in-class profile. Now moving to Dupixent, which achieved several first and only clinical and regulatory milestones since our second quarter earnings call in early August. First, we are pleased to receive US regulatory approval for Dupixent as an add-on maintenance treatment of adult patients with inadequately controlled COPD and the eosinophilic phenotype, marking the first-ever biologic approved to treat this disease and representing Dupixent's sixth indication approved in the United States. Also in COPD, as Len mentioned, we're looking forward to pivotal results in the second half of next year for Itepekimab, our interleukin-33 antibody. If approved in the United States, EU and Japan, Itepekimab could address approximately 1 million former smokers with COPD regardless of eosinophilic phenotypes. In terms of potential future indications for Dupixent, the Phase III ADEPT trial in moderate to severe bullous pemphigoid patients met the primary and all key secondary endpoints. Five times more Dupixent patients achieved sustained disease remission at 36 weeks compared to those on placebo. Dupixent patients were far less likely than patients on placebo to relapse following steroid taper or need rescue therapy during the treatment period. Based on these data, Dupixent is the first and only biologic to achieve significant improvements in disease remission and symptoms in bullous pemphigoid and is the first medicine to show significant steroid sparing in this disease. We anticipate this Phase III ADEPT trial will support regulatory approvals around the world, with the US supplementary BLA submission expected by the end of the year. We also announced results of a second Phase III study of Dupixent in biologic-naive patients with chronic spontaneous urticaria, or CSU, confirming the results of a prior Phase III study in the same population. In this most recent study, treatment with Dupixent met the primary endpoint and, in addition, resulted in a nearly 50% reduction in itch and urticaria activity scores from baseline, with 30% of Dupixent treated patients reporting a complete response or no urticaria by week 24 compared to only 18% of those on placebo. These data, along with the data generated in the first CSU study evaluating biologically naive patients, supported our supplementary BLA resubmission earlier this month, and we look forward to a potential FDA approval early next year, which would mark the first targeted therapy for CSU in a decade. Moving to oncology, starting with Libtayo, which provides a best-in-class foundation for combinations with our other oncology assets. At the World Conference on Lung Cancer, we announced five-year results from the final prespecified overall survival analysis of the Phase III EMPOWER Lung 1 trial, which evaluated Libtayo monotherapy as a first-line treatment for adults with advanced non-small cell lung cancer with more than 50% PD-L1 expression. The late-breaking data showed that at five years, Libtayo monotherapy nearly doubled median overall survival and reduced the risk of death by 41% compared to chemotherapy. There were also no new safety signals observed over five years among those patients. These five-year outcomes data in advanced non-small cell lung cancer compare favorably cross-trial to other PD-1 or PD-L1 antibodies and further support Libtayo's position as the anti-PD-1 backbone for Regeneron's ongoing oncology efforts. Moving on to one such Libtayo combination. At the recent ESMO meeting, we presented updated results of the fianlimab, or LAG-3 antibody in combination with Libtayo in adults with advanced melanoma across three independent expansion cohorts of our first-in-human multi-cohort trial. With longer follow-up, these latest results showed persistent and deepening tumor responses across all cohorts. In post-hoc pooled analysis, 57% of patients responded, with 25% of these patients achieving a complete response. Median progression-free survival was 24 months. Median overall survival was not reached in any of the individual cohorts when the results were pooled. These fianlimab-Libtayo proof-of-concept data showed nearly double the complete response rate, with more than five times greater median progression-free survival than previously reported for anti-PD-1 monotherapies. The fianlimab-Libtayo combination also showed robust clinical activity in subpopulations where there is currently no established standard of care, such as in patients previously treated with anti-PD-1 therapy in the adjuvant or neoadjuvant setting. Of the 13 patients in this subgroup, six patients, or 46%, responded to therapy. Among patients receiving any adjuvant or neoadjuvant systemic therapy, 11 of 23, or 48%, responded to the therapy, including six complete responses. The safety profile of the fianlimab-Libtayo combination was generally consistent with the safety profile of the Libtayo monotherapy and other anti-PD-1 agents, except for higher rates of treatment-related adrenal insufficiency. Ever since the exciting early data with individual checkpoint inhibitors were presented more than a decade ago, it's been widely hypothesized that combining multiple classes of checkpoint inhibitors might meaningfully enhance antitumor activity without exacerbating safety issues. Yet, progress to date has been broadly disappointing. We believe the results generated so far in advanced melanoma for fianlimab and Libtayo suggest it might be the first checkpoint inhibitor combination to demonstrate meaningful additive clinical benefit without significantly exacerbating safety. Our ongoing randomized Phase III trial of the fianlimab-Libtayo combination versus Pembrolizumab monotherapy in previously treated, unresectable, locally advanced or metastatic melanoma is ongoing, with pivotal data expected to read out next year. In addition to melanoma, we're exploring this combination in a variety of other cancer settings that have historically been responsive to anti-PD-1 therapy, including lung cancer, with initial Phase II data for which are expected to read out under this year. Next, to our bispecifics for hematology-oncology. We are pleased that the European Commission approved Ordspono or odronextamab, a CD20xCD3 bispecific for relapsed/refractory follicular lymphoma and diffuse large B-cell lymphoma, marking the first regulatory approval from our bispecific antibody platform. We continue to work on enrollment of our confirmatory studies to support resubmission of our BLA for follicular lymphoma, which we now expect to achieve in the first half of 2025. Linvoseltamab, a BCMAxCD3 bispecific for myeloma, data from the ongoing LINKER MM1 study in patients with relapsed/refractory multiple myeloma continue to mature, with responses continuing to do recall that 14 months of median follow-up among 117 patients, linvoseltamab continues to demonstrate a potentially best-in-class profile in terms of efficacy, safety, dosing, as well as hospitalization burden, with 71% of patients responding to therapy and 50% achieving a complete response or better. Perhaps the most differentiating aspect of our clinical development program for both odronextamab and linvoseltamab in earlier line settings is our plan to evaluate each agent as monotherapy, as well as in limited combinations. While competing CD20 bispecifics are evaluating combinations with linvoseltamab plus rituximab in first-line follicular lymphoma regardless of tumor burden, our Phase III OLYMPIA 1 study is evaluating odronextamab monotherapy compared to R-CHOP. Similarly, in first-line multiple myeloma, our ongoing Phase I/II LINKER MM4 study is evaluating linvoseltamab monotherapy. Furthermore, we are also conducting Phase II studies for linvoseltamab monotherapy in precursor conditions such as smoldering myeloma and monoclonal gammopathy of undetermined significance or MGUS in an attempt to prevent progression to myeloma. Now to our non-oncology hematology pipeline, starting with our C5 program, which is the first combination of an antibody and siRNA that targets the same protein. We expect to present updated results for one potential indication, Paroxysmal Nocturnal Hemoglobinuria, later this year and expect to read out pivotal results in generalized Myasthenia Gravis in the second half of next year. We also initiated our Phase III program in geographic atrophy in dry age-related macular degeneration with initial patient screening now underway. We believe that our systemic approach has several significant advantages over currently approved agents. First, it may avoid the risk of rare but severe eye inflammation and irreversible vision loss that has been observed with currently approved intravitreal treatments. Our systemic approach is also potential to offer convenient treatment of bilateral disease as well. Regarding our Factor XI antibodies, we remain on track to report top-line results by year-end of our proof-of-concept studies for our A2 domain targeting and our catalytic domain targeting antibodies in the setting of prevention of venous thromboembolism following knee replacement surgery. Results of these studies will inform whether to proceed to registration-enabling studies with one or both of these antibodies with the possibility that both antibodies will advance to Phase III, but in different thrombosis indications or in different patient populations. In summary, we continue to drive forward our innovative development pipeline and anticipate reading out several pivotal and proof-of-concept data sets in oncology, immunology, obesity, hematology, and genetic medicines over the next 12 to 18 months while our early research engine has never been more productive with multiple novel programs potentially advancing into the clinic over the same time frame. And with that, I will turn the call over to Marion.

Thank you, George. Our third quarter performance demonstrates Regeneron's ongoing leadership across therapeutic categories. We continue to advance the strength and diversity of our product portfolio. As George described, our pipeline is advancing with several potential regulatory filings and approvals on the horizon, creating both near and longer-term opportunities. I'll begin with EYLEA HD and EYLEA. In the third quarter, combined US net sales were $1.54 billion, a 3% year-over-year increase. EYLEA HD and EYLEA net sales were favorably impacted by approximately $40 million as a result of higher wholesaler inventory levels for EYLEA HD at the end of the third quarter, partially offset by lower inventory levels for EYLEA. As a result, we expect fourth quarter EYLEA HD net sales to be negatively impacted as this increase in wholesaler inventory is absorbed. Together, EYLEA HD and EYLEA captured 44% of the total anti-VEGF category in the third quarter, demonstrating retina specialists’ experience and confidence in both brands. EYLEA HD net sales grew 29% sequentially in the quarter to $392 million, driven by ongoing adoption across treatment-experienced and treatment-naive patients as treatment experience grows, retina specialists reporting to EYLEA HD's durability, coupled with its efficacy and safety as important clinical differentiators. Recent late-breaking data presented at the American Academy of Ophthalmology's annual meeting highlighted EYLEA HD's potential best-in-class profile. As George highlighted, diabetic macular edema patients who switched to EYLEA HD consistently achieved longer dosing intervals and slower retinal fluid re-accumulation. While we anticipate the anti-VEGF category to continue to be highly competitive with both branded and biosimilar products in the marketplace, we plan to further strengthen the EYLEA HD product profile through the anticipated launch of our differentiated prefilled syringe by mid-2025 and a potential approval of the RVO indication, for which registration-enabling data are expected by the end of this year. In the first year since launch, positive physician and patient experiences have propelled EYLEA HD to achieve billion-dollar brand status. With additional growth catalysts expected in 2025, our team is focused on helping even more patients benefit from EYLEA HD. Turning to Libtayo. We continue to make significant progress in the third quarter with global net sales increasing 24% year-over-year on a constant currency basis to $289 million, and US net sales grew 35% to $195 million in non-melanoma skin cancer. Our work to expand the immunotherapy market has resulted in an even greater number of Libtayo patients, and in lung cancer, we continue to gain market share. Outside the US, net sales were $94 million, which does not include $20 million in distributor purchases that shifted to the fourth quarter. We continue to see opportunities to increase Libtayo demand in 2025 with new launches in several markets. Finally, Dupixent continues its remarkable growth trajectory. In addition to the positive data readouts and regulatory updates that George mentioned, we've reached an impressive milestone. Dupixent has now surpassed 1 million patients on therapy across 7 indications worldwide. In the quarter, Dupixent achieved global net sales of $3.8 billion, a 24% year-over-year increase on a constant currency basis, driven by uptake across all indications, age groups, and geographies. In the US, net sales grew 19% year-over-year to $2.8 billion, and Dupixent continues to be the #1 prescribed biologic for new-to-brand patients in all of its approved indications. It's widely recognized by prescribers that Dupixent's dual mechanism of action targeting IL-4 and IL-13 addresses the underlying cause of these type 2 diseases. Demand is strong across the blockbuster indications of atopic dermatitis, asthma, and nasal polyps, and there is opportunity for ongoing market penetration based on unmet patient need. Uptake is also increasing across our recent US launches; new-to-brand prescriptions for prurigo nodularis are up approximately 30% compared to the prior year and EoE new-to-brand prescriptions, including the pediatric indication, are up approximately 40%. In September, Dupixent's label was expanded to include patients as young as 12 years of age who have inadequately controlled chronic rhinosinusitis with nasal polyps, and we estimate approximately 9,000 additional US patients can now benefit from Dupixent. In recent months, Dupixent has been approved to treat COPD in more than 30 countries. We are excited about the opportunity to extend Dupixent's leadership in respiratory disease, which we estimate may benefit more than 300,000 patients in the US alone with inadequately controlled COPD and an eosinophilic phenotype. In the first weeks of the US launch, we've been encouraged by the enthusiasm from physicians and patients for Dupixent as a treatment option in this underserved population. Educational efforts are underway to highlight the importance of type 2 inflammation in COPD and to support patient identification by prescribers while motivating patients to speak with their physician about Dupixent. We've made significant progress in securing access and reimbursement for patients, many of whom are covered under Medicare. With Dupixent's unique clinical profile and first biologic to market advantage, we anticipate the COPD indication will drive meaningful growth for Dupixent. In summary, Dupixent continues to transform the standard of care in the lives of patients worldwide. In addition to current approvals, we look forward to future potential launches in diseases, including COPD in Japan, pediatric EoE in the EU, chronic spontaneous urticaria in the US, as well as global regulatory filings for bullous pemphigoid. In conclusion, our commercial team continues to deliver on our goal to provide Regeneron medicines to an ever-expanding number of patients worldwide. There is significant growth potential within the current and future indications of our medicines, and our pipeline provides meaningful opportunities for growth. With that, I'll turn the call 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 strong financial performance in the third quarter with continued execution driving top and bottom-line growth. Total revenues increased 11% year-over-year to $3.7 billion, primarily driven by higher Sanofi collaboration revenue, continued growth for Libtayo, and US growth of total EYLEA HD and EYLEA. Third quarter net income per share grew 8% from the prior year to $12.46 on net income of $1.5 billion. Third quarter revenues from our Sanofi collaboration were $1.3 billion, inclusive of $1.1 billion related to our share of collaboration profits. Regeneron's share of profits grew 26% versus the prior year, driven by volume growth for Dupixent and improving collaboration margins, with collaboration profitability reaching another all-time high in the third quarter. The Sanofi development balance was approximately $1.8 billion at the end of the third quarter, reflecting a reduction of approximately $200 million from the end of the second quarter and approximately $520 million from the end of 2023. Moving to Bayer. Third quarter ex-US net sales of EYLEA and EYLEA 8 mg were $932 million, up 9% on a constant currency basis versus the prior year. Total Bayer collaboration revenue was $391 million, of which $368 million related to our share of net profits outside the US. We recorded $35 million of sales for Inmazeb, our antibody cocktail for Ebola, in the third quarter related to deliveries to the US government under our existing agreement. We still expect 2024 Inmazeb sales to be in line with 2023 sales of approximately $70 million. Other revenue in the third quarter was $114 million. We expect other revenue will increase sequentially in the fourth quarter of 2024, but on a full-year basis, it is expected to be lower than 2023. Now to our operating expenses. R&D expense was $1.1 billion in the third quarter. The increase in R&D expense versus the prior year was driven by ongoing investments in our pipeline, including late-stage oncology programs and increased clinical manufacturing costs to support ongoing programs. SG&A grew 15% from the prior year to $613 million in the third quarter, primarily reflecting ongoing investment to support the launch of EYLEA HD. Third quarter 2024 gross margin on net product sales declined to 89% compared to 90% in the prior year, primarily reflecting higher start-up costs for our fill/finish manufacturing facility. Now to cash flow and the balance sheet. Regeneron generated approximately $2.6 billion in free cash flow through the first nine months of 2024 and ended the quarter with cash and marketable securities less debt of approximately $15.6 billion. Through the first nine months of 2024, we have repurchased over $1.6 billion of our shares, including $738 million in the third quarter. Given our long-term growth potential, we continue to see share repurchases as an efficient use of capital and had approximately $2.9 billion available for repurchases as of the end of the third quarter. Finally, we made some minor changes to our full-year 2021 financial guidance based on our year-to-date results, narrowing ranges across most guidance items. A complete summary of our latest full-year 2024 guidance is available in our press release issued earlier this morning. In summary, Regeneron delivered strong financial results in the third quarter, and our focused investments continue to position us to drive long-term growth. 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. Operator, can we please go into our first question?

Thank you. Our first question comes from Chris Schott at JPMorgan. Your line is now open.

Hi. This is Taylor Hanley on for Chris Schott. We just had a question on EYLEA. So with Amgen launching their biosimilar, how are you thinking about EYLEA going forward? And what levels can you pull to potentially accelerate conversion to high-dose EYLEA? And how are you thinking about pricing for the franchise more broadly? Thank you.

We may have some extra comments on that. But look, EYLEA is a fantastic product. We have delivered probably somewhere in the neighborhood of around 100 million or more injections with EYLEA. And so the performance and safety of the product, our transparency with safety issues that may arise over the past decade, I think has given physicians and their patients a lot of comfort with EYLEA, and you see some stickiness of that product. Nonetheless, we think that EYLEA HD is a differentiated product, and we are continuing to work on using the standard approaches of education and informing the doctors about the potential use in patients, providing them with more data, as George referred to some of the long-term data is rather striking. We know that there is a biosimilar in the market for EYLEA, not for EYLEA HD, and we know it will be competitive, but we think we'll be able to compete well.

Okay, next question please, Shannon.

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

Evan, we don’t hear you. Maybe we’ll come back to Evan. Shannon, why don’t we go to the next.

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

Hi, guys. Good morning. Congrats on the quarterly results and all the progress. Can you reiterate your confidence in EYLEA HD quarter-over-quarter growth going into Q4 despite the negative impact due to wholesaler inventory? And are you seeing a tailwind with the overall franchise yet due to the removal of product from a major supplier of Avastin?

Let me address both of those points, Tyler. First, the quarterly performance showed growth for EYLEA and EYLEA HD. Regarding EYLEA HD specifically, we have strong confidence in its product profile, the interest from the retina community, and the robustness of our safety and clinical data is evident. I do want to highlight that there was an inventory situation during the quarter. While we won't provide guidance for the fourth quarter, I want to make you aware of the positive impact of about $40 million due to increased wholesaler inventory levels for EYLEA HD at the end of Q3, although this was partially offset by slightly lower wholesaler inventory levels for EYLEA. We wanted to share this information, and we remain confident in EYLEA HD's performance, but that inventory will certainly be utilized in the fourth quarter.

Looking ahead, I believe Marion mentioned that launching our prefilled syringe by the middle of the year will serve as a significant catalyst for growth. We have put considerable effort into ensuring that when we introduce a product to the market, it can endure millions of injections. Unlike some competitors who may have to use a filter needle due to issues with their product, we aim to avoid such complications and are carefully evaluating our product to prevent any inflammation. It's important to note that in this market, excessive inflammation can negatively impact products, leading to serious conditions like retinal vasculitis and potential vision loss. We are very mindful of these issues, and I believe physicians will also be cautious with any new launch, even in light of biosimilars. They will likely want to evaluate options closely, recognizing the reliability of EYLEA. Thus, we will approach this launch methodically, as we are focused on the long-term success.

Tyler, I also want to cover your question related to the removal of product from a major supplier of Avastin in the marketplace. So we're very well aware of that. And certainly, our teams are actively involved in retina offices supporting staff and working with them on any challenges that present. I would share that at this point, there still is Avastin inventory from pine in the market. I think it's anticipated to run out within a couple of weeks. So we haven't seen a material uptake in EYLEA HD or EYLEA related to that yet, but we're staying very close to that situation and supporting our customers.

Thank you. Next question please, Shannon.

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

Hi there. Good morning. Thanks for taking my question. On the HD prefilled syringe, can you talk about the potential inflection in use that could catalyze next year, including how the differentiation of that prefilled syringe might resonate? And maybe also elaborate on some of the gating factors to development there, timeline sounds like they've been pushed out a little bit. Thanks.

Yes. As I said, we anticipate bringing that to the market by the middle of next year. I believe already or almost immediately, Bayer will be bringing the same device to the market with EYLEA HD outside of the United States. So we have a high degree of confidence. There are some additional requirements that you have to fulfill inside the United States, which we are working through. I think we will have a differentiated product opportunity there. So you're right, Brian, it's possible that there could be an inflection when that comes to market because there is a preference for the prefilled syringe.

Okay. Thank you. Next question please.

Our next question comes from the line of Carter Gould with Barclays. Your line is open.

Yeah. Good morning. Thanks for taking the question. Maybe for Leonard and Chris, just now in the wake of Amgen potentially being on the market has driven any sort of change in your conceptual thinking about the pace of R&D investments going forward or your capital allocation priorities, or are you potentially leaning into buybacks or further rolling out or delaying a potential dividend? Any color on that front would be helpful.

Well, they say imitation is the best form of flattery. So we're pleased that Amgen is investing their time in imitating our products. Our focus is on bringing new products to market, which is the core of this industry. While biosimilars have their place, we believe that Regeneron is best positioned to deliver innovative products. We have over 40 products in clinical development, with many in Phase III. As George outlined, there are numerous exciting programs with plenty of data readouts. Our spending will not be restricted by the entry of biosimilars; instead, we will invest based on the opportunities we identify. We maintain a strong balance sheet, good earnings, and the capacity for significant investments. George has established a highly prolific research and development organization in the industry, and it would be unwise not to invest in that, so you can expect an increase in investments. The main question always is whether these investments will yield returns. While our past performance won’t guarantee future results, the over 10 or 12 products that George and the team have successfully launched are promising indicators of what's ahead. With more than 40 projects in development, we are very optimistic about our future product offerings.

Thanks, Len. Next question please, Shannon.

Our next question comes from the line of Terence Flynn with Morgan Stanley. Your line is now open.

Great. Thanks for taking the question. I know you have some upcoming Factor XI readouts here before the end of the year. Maybe you could just tell us what you're looking for to make the decision about whether to advance those into a Phase III program and how you're considering them versus each other and also versus the standard-of-care. Thank you.

Yes. This is George. We're very excited about our Factor XI program because we think it's very different from anything else that's out there. We chose to take a different approach where we attack Factor XI in two different ways, what we call our A2 domain antibody or catalytic domain antibody. Our A2 domain antibody is not a complete blocker of Factor XI; it actually is more like a complete Factor XII blocker. It's expected to not have as profound an effect on the coagulation pathways but to have a much milder safety profile. In contrast, we believe that our catalytic domain antibody is the best-in-class blocker of Factor XI and will come with the best ability to control coagulation among all agents that are attacking this pathway. But of course, it will also have presumably a higher safety load than our A2 domain antibody. So we think it's very exciting to have these two parallel but very distinguished approaches. We hope to be able to show that both of these substantially control thrombo formation in the clinical trials that we now have running. We hope to then in the future decide based on how well they each control and their expected safety profile, we expect the ability to consider multiple indications that we can evaluate each one for different potential indications for one versus the other. So these are sort of a pipeline in and of themselves able to attack, we believe, a variety of different coagulation settings, and each one can be used differentially and provide a different profile of efficacy versus safety as might be needed in the different clinical settings.

I just wanted to add that what George has taught me over the years is that not all antibodies are created equal, and not all blockers of the pathway perform the same way. We have in-house pharmacodynamic data suggesting that the antibodies developed and chosen by Regeneron give us a competitive advantage in outperforming other Factor XI antibodies or small molecule competitors. It's challenging for small molecule competitors to reach high doses due to off-target issues, and not everyone can access the best antibodies. We believe we have the technology to differentiate our offerings. Ultimately, the proof will be in the results when we obtain the data and evaluate performance.

Okay, thank you. Next question please.

Our next question comes from the line of Chris Raymond with Piper Sandler. Your line is now open.

Thank you. Maybe just a follow-up on the last question about the supply issue with Pine and potentially others exiting the market. Maybe just stepping back, compounded Avastin has seen supply and quality issues before. Do you see this episode as different from prior disruptions? We had a KOL tell us that he believes this marks sort of the beginning of the end for Avastin. I'd love to hear your thoughts on that. And maybe as a follow-up, if Avastin is likely to play less of a role here, does this not provide more of an opening for a biosimilar option?

So Chris, let me take the impact and the situation with Pine and say that I think that probably what we're hearing is that because of the prior Avastin shortages last year around this time, the same thing occurred, offices and practices are getting used to how to deal with the situation. Obviously, the confidence in Avastin goes down in the supply. So certainly, it's important. I see the evolution that you're hearing is because it's a situation that has been dealt with before. We certainly want physicians to have a choice in prescribing the anti-VEGF category product brand that they think is best for their patients. Certainly, I think it is a competitive marketplace, but as we show in growth of our franchise this quarter, we did last quarter as well. We certainly think that both EYLEA HD and EYLEA are both positioned very well in this competitive marketplace.

Thanks, Marion. Next question please, Shannon.

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

Thank you. Good morning. Can you just elaborate on the drivers for the pricing pressure noted for EYLEA HD, and whether these pressures are going to be ongoing going forward? And just in that context, maybe discuss kind of your outlook for overall growth of the branded anti-VEGF market in the context of the biosimilars. Thank you.

As we consider the pricing pressure in the anti-VEGF category, it's affecting all products, including both branded and biosimilar options, and this trend aligns with other competitive sectors. It's crucial to recognize that the products physicians prefer to prescribe are often those with proven experience, a solid safety profile, and effective results. In the case of EYLEA HD, its durability is an added advantage. These factors are significant for us to effectively compete in the anti-VEGF category. Regarding overall growth in this market, it is likely in the mid-single-digit range. To address the pricing pressure specifically, it's particularly noticeable for EYLEA, especially considering it has been on the market for over a decade. EYLEA HD stands out due to its clinical profile, providing physicians with both confidence in clinical results and safety, along with a demonstrated level of durability that we continue to observe. Our clinical data also supports this long-term perspective.

Thank you. Next, move to the next question please, Shannon.

Our next question comes from the line of Mohit Bansal with Wells Fargo. Your line is now open.

Thank you for taking my question. I would like to understand how well EYLEA is performing compared to your internal expectations, especially since it seems like about 25% adoption has occurred at this point. It appears to be growing very quickly, so I'm curious about the dynamics we should consider here and if there are any strategies you can implement to further boost uptake.

So Mohit, thanks for the question. Obviously, we don't give specific guidance on conversion or the size of the market, but we do talk about what we think the catalysts can be, and I do feel that we have a bunch of catalysts next year: the potential approval and data for RVO, more importantly, perhaps the prefilled syringe by mid-year. So I think that next year, we could see a little bit of an acceleration. Obviously, we're working very hard. It's a great product. But these things don't happen overnight because people do love EYLEA. And it is more sticky than one might have anticipated, but I think the progress is solid, and we expect it to keep going.

Okay, let’s move to the next question please.

Our next question comes from the line of Trung Huynh with UBS.

Good morning. This is Trung from UBS. Thank you for addressing my questions. I want to shift focus to the obesity program regarding the ongoing Phase II study of trevogrumab plus garetosmab and the GP1 study. It appears you have recently increased the trial size from over 620 to 1,000 participants and added three new arms. This brings the total to 13 investigational arms, indicating a desire for a comprehensive approach. Could you explain why these protocol changes were necessary and your reasons for wanting to further expand the trial? Thank you.

Could someone please repeat that question because I really couldn't understand it at all? Go ahead.

Definitely. Yes. Just the ongoing Phase II obesity study of trevogrumab plus garetosmab, with and without. So you recently increased the trial size, previously it was 620 plus. You also added two new arms. Why do you think those protocol changes are necessary, and why would you like to further expand the trial? Thank you.

Yes. I think what you're probably referring to is that we added additional dosing arms in our trial to expand different doses of the hopefully muscle-enhancing treatments. That's the major reason that the trial was enlarged, so we would have broader information on different doses and their effects on muscle preservation.

We didn't see any new safety signals in the healthy volunteer study, which allowed us to move forward. I believe it's just a matter of exploring additional doses.

Trying to find the right mix of antibodies with semaglutide to maximize the quality of the weight loss. Let’s move to the next question please.

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

Hi, everyone. Thank you for taking my question. I apologize for the earlier issue. I wanted to follow up on the topic of obesity. George, you've mentioned the significant need for quality in weight loss, which I believe is crucial. Could you discuss the regulatory landscape regarding muscle preservation or muscle-building products? I understand the FDA has been somewhat cautious and is primarily focusing on weight loss, but I'd like to hear your thoughts on how this might progress over the next few years.

Yes. I guess what you're referring to is obviously we all know, and it's been widely noted and acknowledged that in the setting of the very rapid weight loss that can be caused by these GLP-related agents, you get significant lean body and muscle loss of up to 30% to 40% of the weight loss, especially because most of these patients actually go off these treatments and then often cycle. This can actually lead to cumulative loss of muscle over time, which can actually be quite catastrophic. We may be creating a secondary problem here over time as people cycle on and off these treatments. So our approaches are intended to maintain the muscle. That said, the agents because they're promoting muscle remember, muscle is the major non-essential spender of energy that is renowned for its ability to expand energy. We've seen in the animal models that it can also cause our approaches when you maintain muscle, you are increasing the metabolic rate. So you're actually expending more calories, so you actually can lose more weight while you're gaining the muscle or preserving the muscle because the muscle itself is burning up the calories or using up the calories. So the easiest regulatory path will be if our approach is, as has been seen in the preclinical studies, actually result in more weight loss but a better composition of that weight loss. So that one won't even have to actually rely on a muscle regulatory endpoint, just on the increased weight loss itself. Of course, one will then hopefully be able to describe this all part of ongoing discussions with regulatory agencies that not only might you be seeing increased weight loss, but the body composition results will be better. So the simplest regulatory path will be just by increasing the actual weight loss, and then you'll be able to show secondary endpoints that you are doing better on the composition of the weight loss as well. That said, we are going to be measuring metabolic parameters. We're also going to be measuring functional assets, as well. And those are, of course, regulatory paths as well that will be more complicated and probably require larger and longer studies than just the weight loss studies themselves. So of course, we expect to be improving metabolic endpoints. We expect to be improving functional endpoints whether we're going to be needing those as exploratory or descriptive endpoints or whether we're going to end up relying on them for approval remains an open story. But the goal, of course, is to show these benefits in the setting of maintenance of the muscle while maintaining or actually getting greater weight loss. I should also point out that in our pipeline, we have a variety of what we call Unimolecular solutions, a whole series of molecules that have the ability all within the same molecule to do all of these things. And obviously, those will all have their own different regulatory path, some of which might be much more expedient in terms of what endpoints you can use for approval and so forth.

Thanks, George. Let’s move to the next question, Shannon.

Our next question comes from the line of David Risinger with Leerink Partners. Your line is now open.

Yes, thank you. I have just one question. Regarding next-generation product development, Regeneron had significant success with EYLEA HD. Can you discuss your efforts to create a next-generation version of Dupixent, specifically if it will be administered less frequently? Thank you.

All we can say is that we are constantly working on both improving approaches for something where we already have important products such as in the Dupixent class, as well as coming up with entirely new and different products and approaches as well. And as you might imagine, we delivered with HD. I mean this is what we're trying to do all the time. We're trying to improve the current approaches but we're also trying to come up with an entirely different next-gen approach as well. That's what we do here at Regeneron.

Thanks, George. Time for two more questions, Shannon.

Our next question comes from the line of William Pickering with Bernstein. Your line is now open.

Hi, thank you for taking my question. Do you think that the rate of biosimilar erosion for Lucentis is a good proxy for what we can expect for EYLEA? I think they saw about 25% of volume switch over in the first 12 months. And are there any important differences in the commercial dynamics to keep in mind? Thank you.

I would just say that it's very early to comment. Throughout today's conversation, we've discussed the factors that instill confidence in EYLEA, including its demonstrated use worldwide, but it's too soon to comment on a product that hasn't been utilized in a real-world setting yet.

I think it's also important. The situation is very different because at the same time, there are patients on EYLEA who might have a choice of going to a biosimilar, staying with EYLEA, or actually moving to a differentiated product profile, which is EYLEA HD. So that's a very different sort of situation than you had with just the Lucentis erosion situation.

Great point.

Thank you. Shannon, let’s take our last question.

Our last question comes from the line of Cory Kasimov with Evercore ISI. Your line is now open.

Hi, good morning, guys. Thanks for fitting me in. I wanted to follow up on Carter's question earlier about capital allocation priorities. I'm sure you're pretty frustrated by the market reaction to recent developments around EYLEA. I know you have nearly $3 billion left in your authorized share repurchase. But have you given any thoughts to an ASR? And what are your evolving views around a dividend given that you already have over $15 billion in net cash on hand? Obviously, you have another significant inflection in additional cash generation not too far down the road. Thank you.

We have lots of discussions on this. We don't really have anything more to add than we've said publicly, which is perhaps the best opportune time to think about the dividend is when we have paid off the development balance to Sanofi, which we anticipate should be somewhere around the end of 2026. But beyond that, how we repurchase stock, when, whether, et cetera, et cetera, is something that we really don't discuss until it's happening.

Okay. Thank you, Len, and thanks to everyone who dialed in for your interest in Regeneron. We apologize to those remaining in the Q&A queue that we did not have a chance to hear from. As always, the Investor Relations team here at Regeneron is available to answer any remaining questions you may have. Thank you once again. Happy Halloween, happy Diwali. Have a great day.

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