spk08: Thanks, Mark, and thanks to everyone joining today's call. The fourth quarter of 2021 capped off a terrific year for Regeneron. Our performance was driven by strong execution across the organization, despite the ongoing challenges posed by COVID-19. We're all proud of the incredible work and dedication of our employees who continuously deliver on our mission to bring important medicines and novel medical breakthroughs to patients in need. Throughout 2021, we delivered strong top and bottom line growth. Revenues, excluding our COVID antibody cocktail, grew 19%, a testament of our diversified and strengthening core business. Our innovative and world-class pipeline advanced across a wide variety of diseases. We also unveiled initial clinical data and pipeline advancements from our Regeneron genetics medicines portfolio. which has the potential to unlock significant long-term value. Additionally, we return substantial cash to shareholders in the form of share buybacks. In 2021, we spent approximately $1.7 billion repurchasing over 3 million shares. For ILEA, 2021 global sales grew 19% to $9.4 billion. Even after 10 years on the market, and millions of injections later. We continue to view ILEA as an enduring product with significant future opportunity despite new market entries. In the second half of the year, we look forward to the results from our Phase 3 Aflibriset 8-milligram high-dose program. If those data continue to support that Aflibriset 8 milligrams provides extended dosing durations, Without compromising on safety and efficacy, Aflibicet 8mg has the potential to complement and enhance our retinal franchise. With Depixent, we're delivering on a goal of transforming the treatment of type 2 inflammatory diseases. 2021 global sales of Depixent were $6.2 billion, representing 53% growth for the year. Looking ahead, Depixent's outlook is bright. There are significant opportunities to increase market penetration rates in approved indications. And we are in the midst of a wave of new data submissions and launches in potential new indications further fueling Dupixent's growth. In oncology, Liptio continues to thrive in the approved non-melanoma skin cancers. We look forward to potential Liptio plus chemotherapy opportunities approval later this year in the broader population of non-small cell lung cancer patients. Our oncology footprint continues to expand. We have advanced many candidates and combinations into the clinic with a range of antibodies, bispecifics, and co-stimulatory bispecifics across many cancer settings. This year, we look forward to sharing what we hope will be groundbreaking data and difficult-to-treat solid tumors such as prostate cancers and ovarian cancers, both of which are conditions with historically low response rates to immunotherapy. We also remain encouraged in the progress of our maturing CD3 bispecifics. We are confident in the overall safety and efficacy profile for a dronextamab, our CD20 by CD3 bispecific. We are forging ahead with REGN5458, our BCMA by CD3-bispecific, which we believe will play an active role in the treatment of multiple myeloma given its competitive profile. Last but not least, we are immensely proud of our rapid response efforts against COVID-19. In 2021, with Gencov, our antibody cocktail was administered to millions of people globally, making a major impact during the darkest days of the pandemic. Based on preclinical data, we recently announced that Regencov is highly unlikely to be active against the Omicron variant. Appropriately, the FDA amended the emergency use authorization for Regencov, limiting its use in the U.S. in light of the Omicron variant being dominant. Regeneron remains committed to helping fight the COVID-19 pandemic, we are progressing next-generation antibodies that are active against Omicron Delta and other variants of concern. We are scaling up manufacturing efforts and completing the necessary requirements to begin clinical trials for next-generation candidate in the coming months. Concurrently, we are working closely and collaboratively with the FDA and other global regulatory authorities to establish and define clinical pathways to bring additional safe and effective monoclonal antibody treatment options to patients as quickly as possible. As one of the leaders in the fight against COVID-19, our Velocisweep platform of technologies makes us uniquely positioned to promptly develop and deliver potentially life-saving medicines. As the COVID-19 story transforms, from pandemic to endemic, we believe there will remain a significant opportunity to use our next generation monoclonals as a prevention for those immunocompromised individuals who do not respond adequately to COVID-19 vaccines. In addition, monoclonal antibody therapy is likely to play an ongoing role in treatment for infected individuals. In conclusion, 2021 was another high-performance year for Regeneron, with strong commercial results from our in-line marketed products, 30-plus pipeline candidates progressing through clinical trials, our discovery efforts firing on all cylinders, a growing portfolio of highly productive external collaborations, and our strong financial position with over $12 billion in cash and marketable securities and Regeneron is extremely well positioned for the future. Now I will turn the call over to George.
spk11: Thanks, Len. I'll start by briefly addressing our novel monoclonal antibodies for COVID-19. As Len mentioned, we are rapidly developing next-generation antibodies that retain potency against Omicron and other variants of concern. Early in 2019, we anticipated that the virus would mutate and thus began generating large pools of virus-neutralizing antibody candidates from both human survivors and our velocity mice. We have continually evaluated and refreshed this pool and now have next-generation candidates that, based on preclinical studies, effectively neutralize Omicron and other variants of concern. We're on track to initiate clinical trials with the first of these in the coming months. In addition, we are in discussions with the FDA regarding how to streamline the development program for monoclonal antibodies, considering the unwavering unmet need and demand for these medicines, especially with potential future virus variants in mind. As Len already highlighted, since we believe that monoclonal antibodies will continue to play an especially important role in the treatment and future protection of the several million immunocompromised people in the United States alone, we are committed to undertaking a development pathway that will make this possible in the near future. Moving on to ophthalmology. At the upcoming angiogenesis meeting, we will present the final Phase II data from the Aflibricep 8 mg Candela study in patients with wet AMD. In this study, Aflibricep 8 mg, given at the same protocol-specified dosing schedule as currently approved ILEA 2 mg, met its primary safety endpoint with measures of drying numerically favoring the 8 mg dose over the 2 mg dose. These phase two results give us more confidence that the upcoming phase three readouts have the potential to show that the higher eight milligram of filibrocept dose can at least match the efficacy and safety of ILEA, but with more convenient dosing. Moving on to Dupixent. Building on the outstanding clinical success Dupixent has shown so far across a wide spectrum of allergic or type two inflammatory diseases, the second phase three study in prurigo nigellaris recently met primary and key secondary endpoints, making Dupixent the first and only systemic medicine to demonstrate such success in this indication. These data confirm the results from the first Phase III trial, where 60% of Dupixent patients met the primary endpoint of its reduction compared to 18% of placebo patients at 24 weeks. Nearly three times as many Dupixent patients experienced reduced skin lesions compared to placebo as well. Pharygo nodularis marks the sixth disease for which dupixin has demonstrated profound benefit for patients, providing convincing evidence that the IL-4 and IL-13 pathways inhibited by dupixin are the key drivers of the type 2 inflammation underlying all of these diseases. We have to appreciate how remarkable the dupixin story is in terms of the important benefit it provides for the many patients across this diverse set of clinical conditions. together with its well-established safety profile, and highlights how Dupixent is delivering on its promise of providing a pipeline in a product. At the upcoming Quad AI meeting, in addition to the other important Dupixent updates, we will present pivotal results for the recently top-line studies in eosinophilic esophagitis, or EOE, and for the first chronic spontaneous urticaria, or CSU, study. EOE is a complex disease, and we are excited to share these data with the scientific community and patients. Our first regulatory submission for EOE in adolescents and adults is underway, with regulatory submissions for prurigo and angiolaris also starting in the first half of this year. Anticipated flow of Dupixin-related clinical data updates continues. We are planning on reporting results of an additional Phase III study in CSU, this time in omelizumab-experienced patients and also for the chronic cold-induced urticaria indication in the second half of this year. These represent more difficult-to-treat patients or conditions and present a higher bar for DUPIXA. We're looking forward to results of these pivotal studies. Moving on to oncology and first liptio. Progress in oncology portfolio includes pivotal readouts and regulatory filings for liptio, presented and anticipated data readouts for our bispecifics, as well as multiple upcoming milestones with novel diversified pipeline entrants. As Len mentioned, the Leption chemotherapy combination for patients with non-small cell lung cancer is under review at the FDA with a PDUFA date of September 19, 2022, which could address a larger portion of the patients with lung cancer. In hematology, at the American Society of Hematology annual meeting, we presented encouraging data for Regen 5458 are BCMA by CD3 bispecific investigated for relapse or refractory multiple myeloma. With safety data that has shown no grade 3 or higher cytokine release syndrome to date and strong efficacy data, we believe our investigational agent is promising and has the potential to be competitive in this indication. We are planning on investigating this product for earlier lines of myeloma therapy in combination with standard of care, and are excited about the combination with an appropriate co-stimulatory bispecific, which could further enhance responses. Our next demand, our CD20 by CD3 bispecific, has the potential for a best-in-class efficacy profile in both follicular lymphoma and diffuse large B-cell lymphoma, and our updated step-up dosing protocol may mitigate safety concerns and decrease the need for hospitalizations to manage cytokine release syndrome. In terms of progress, of our bispecifics for solid tumors. As previously disclosed, we are observing early signs of activity for our MUX16 by CD3 bispecific monotherapy developed for late stage ovarian cancer, and we are excited to be sharing these early data later this year. In addition to monotherapy, the MUX16 by CD3 bispecific is being investigated in combination with Lactio, and in a first of its kind, in a combination trial with a MUX16 by CD28 bispecific. These combinations are in early stages and are advancing through dose escalations. Later this year, we are hoping to share initial results for a unique bi-paratopic met-by-met antibody studied in advanced non-small cell cancer patients with met protein alterations. Early signs of clinical activity we have observed so far with the naked met-by-met bispecific antibody, especially in patients with met overexpression, bode well for our follow-on agent, the met-by-met bispecific antibody drug conjugate, which is now enrolling patients in a Phase I study. We're also excited about our early-stage EGFR by CD28 co-stimulatory bispecific program for lung and other cancers. For prostate cancer, we are expecting initial readouts from our first co-stimulatory bispecific, PSMA by CD28, later this year as well. PSMA by CD28 is progressing through dose escalation in combination with Liptio. We are excited about the potential of our broad oncology portfolio, which includes multiple Phase I, II, and III assets. As many are beginning to believe, the future is going to involve the right combination of targeted immunotherapy agents. Concluding with our Regeneron genetics medicines efforts, we and our collaborators have made significant strides in expanding the capabilities and scale of our groundbreaking work in genetics medicines. In terms of our siRNA collaboration with Alnylam, Alnylam HSD is progressing through healthy volunteers, and initial data in NASH patients are anticipated by the middle of this year. For the C5 siRNA and antibody combination, another first of its kind, Healthy volunteer data were presented at ASH, demonstrating PK and PD results supportive of the monthly subcutaneous dosing regimen selected for pivotal studies. Phase III studies of the combination for paroxysmal nocturnal hemoglobinuria, or PNH, were also initiated. Recall, in PNH, we are planning to test our combination in both naive and switch patients tested against standard care therapies including raviolizumab and eculizumab. Also, El Nilem has recently announced submission of the CTK application for El Nilem APP, the industry's first ever investigational RNAi therapeutic for CNS diseases. This agent will be evaluated in both the relatively rare disease driven by amyloid precursor protein known as cerebral amyloid angiopathy, or CAA, as well as in early onset Alzheimer's disease. Finally, later this quarter, we in INTELLiA will provide an update on our joint TTR CRISPR-based knockout program for transthyretin amyloidosis. This will include additional ascending dose interim clinical data from the polyneuropathy arm of the ongoing INTELLiA 2001 Phase I study. We have also expanded the study to include patients with transthyretin amyloidosis with cardiomyopathy. which we believe will address an even broader patient population. We are very excited by our large and diverse pipeline of siRNA candidates that we are advancing with L-nylin, ranging from targeting the liver, the brain, and the eye, as well as our CRISPR-based approaches in collaboration with Intelia and our viral targeted gene delivery programs, such as with Decibel. While still early, we think these groundbreaking approaches have the potential to change the practice of medicine. And with that, I will turn the call over to Mary.
spk05: Thank you, George. Our fourth quarter business performance demonstrated the strength and resilience of our inline brands and creates a foundation for commercial success as we prepare for future launches. Starting with Aliyah, we recently announced fourth quarter U.S. net sales of $1.55 billion and $5.79 billion in 2021. This represented 17% year-over-year U.S. growth for the full year, which is noteworthy for a brand 10 years post-launch. ILEA reached record share across all approved indications and is the recognized leader in a category that continues to grow due to favorable demographic trends. ILEA remains physicians' top choice for patients with indicated retinal diseases and due to its demonstrated efficacy, safety, dosing flexibility, and unsurpassed real-world experience, with more than 40 million administered injections worldwide. We are also excited about ongoing strategic initiatives that position our retinal franchise for future growth, such as our educational efforts in place across existing indications where many patients don't receive the treatment they need. Beyond ILEA, we are encouraged by promising early results for high dose of Flibercept 8 milligram, which, if supported by Phase III clinical results, potentially represents next-generation treatment for a range of eye diseases. Turning to Liptio, where global net sales in the fourth quarter were 121 million, in the U.S., net sales reached 81 million. In advanced cutaneous squamous cell carcinoma, which currently drives the majority of performance, Leptio is the number one systemic treatment, and we saw steady growth as the market continued its post-COVID recovery. In advanced basal cell carcinoma, Leptio is also rapidly being established as standard of care in patients who have progressed or are inappropriate for hedgehog inhibitors, building on our strength in non-melanoma skin cancers. In advanced non-small cell lung cancer, we are making progress in the launch of our monotherapy indication, with a steadily growing prescriber base. There is also significant opportunity in the chemotherapy combination setting, and if proved, Leptio would be available for a much broader range of first-line lung cancer patients than for monotherapy alone. Our experience is that medical oncologists consider combination treatment first and reserve monotherapy for a much smaller group of patients, which in part has limited Leptio uptake in lung cancer to date. Briefly turning to our cardiovascular franchise, our treatment for patients with HOFH was successfully launched in 2021 and is already the standard of care. We continue to see initiations in both switch and category naive patients. In 2021, we are focused on employing innovative efforts to identify patients not currently diagnosed with HOFH. Onto Depixent, which grew 51% in global net sales in the fourth quarter year-over-year to $1.77 billion. In the U.S., net sales grew 46% to $1.35 billion. Depixent is well-positioned for ongoing rapid growth based on significant unmet need in existing and potential new disease areas, with anticipated expansion into even younger age groups and new geographies worldwide. In atopic dermatitis, prescribing trends are strong across the spectrum of moderate to severe disease. Depixent is healthcare specialists' first-line systemic treatment of choice due to several highly differentiating product characteristics, including its dual anti-IL-4 and IL-13 mechanism of action, compelling efficacy and rapid symptom relief, well-established safety profile with no risk of serious infections due to immunosuppression, and clinical data in children as young as six months. If approved, we look forward to expanding Dupixent's skin indications to include babies and young children with atopic dermatitis, as well as two new dermatologic indications. There are no currently approved biologic medicines for Paragonodularis, where we estimate approximately 75,000 patients may benefit from Dupixent in the U.S. alone. We're also progressing an important opportunity to help chronic spontaneous urticaria patients. Dupixent is also steadily growing in the highly competitive asthma space. We see ongoing potential to differentiate Dupixent in moderate to severe disease through its competitive profile, including a broad label that allows use in uncontrolled steroid-dependent patients, regardless of their acinophil levels, as well as use in patients as young as six years of age. Dupixent is also the preferred treatment of ENTs and allergies and chronic rhinocytositis with nasal polyps, regardless of prior surgery, and contributes meaningfully to our business. We are also progressing our launch plans for eosinophilic esophagitis, a gastrointestinal disease with substantial unmet need. We estimate at least 50,000 patients in the U.S. could benefit from Dupixent if approved. We've received positive feedback from key opinion leaders on the strength of our data and lack of suitable treatment alternatives for this serious disease. In summary, in 2021, our commercial team delivered strong growth across the portfolio. Our momentum and new launch opportunities position us well for the future growth. Now I'll turn the call over to Bob.
spk10: Thanks, Marion. My comments today on Regeneron's financial results and outlook will be on a non-GAAP basis where applicable. Regeneron's fourth quarter capped off a strong year. In the quarter, we delivered top and bottom line growth driven by strong execution within our core business. Fourth quarter total revenue grew 104% year-over-year to $5 billion. Excluding revenues related to the COVID-19 antibody cocktail, Total fourth quarter revenue grew 17% year-over-year to $2.7 billion, demonstrating continuing strength of our core business. Fourth quarter total diluted net income per share was $23.72 on net income of $2.7 billion. Starting with RegenCOVE. In the fourth quarter, we delivered the remaining 1.1 million doses from our September 2021 U.S. government supply agreement and recognized 2.3 billion of U.S. net sales. In accordance with our global collaboration with Roche, the amount of manufactured products supplied by each party to the global market resulted in the recognition of a true-up payment related to Roche's share of profits. As a result, in the fourth quarter, we recognized a $260 million charge on in cost of goods sold, in recorded no Roche collaboration revenue. As mentioned, we completed all deliveries under the September 2021 U.S. government supply contract in the fourth quarter. With the FDA's recent amendment to Regencov's emergency use authorization, we do not expect to record any U.S. Regencov sales in the first half of 2022. I will now move to our collaborations, starting with Bayer. Fourth quarter 2021, ex-US ILEA net product sales, as reported to us by Bayer, were $934 million, growing 9% on a reported basis and 12% on a constant currency basis. Total Bayer collaboration revenue was $372 million, of which we recorded $354 million for our share of net profits from ILEA sales outside the U.S. Total Sanofi collaboration revenue was $518 million in the fourth quarter of 2021, Despite seasonally higher fourth quarter operating expenses, our share of the profits from the commercialization of the Pixon and Kevzar was $388 million, which compares favorably to our share of profits of $230 million in the fourth quarter of last year. Moving now to fourth quarter 2021 operating expenses. R&D decreased slightly to $639 million, primarily due to lower spending on RegenCOBE development as compared to the fourth quarter of 2020. SG&A expense increased 30% year-over-year to $495 million, primarily due to costs related to growth initiatives for ILEA and higher headcount-related costs. Cost of goods sold were $559 million, primarily related to Regencove manufacturing costs, and as I mentioned earlier, the recognition of the $260 million true-up payment to Roast for their share of profits related to the COVID antibody cocktail. Finally, the fourth quarter 2021 effective tax rate was 12.7%. Shifting now to cash flow in the balance sheet. For the year, Regeneron generated $6.5 billion in free cash flow and ended the year with cash and marketable securities less debt of $9.8 billion. In the fourth quarter 2021, we exhausted the remaining balance on our $1.5 billion share repurchase authorization, and in November, we announced a new $3 billion share repurchase authorization. Across both, we repurchased approximately 850 million of shares in the fourth quarter of 2021. We continue to be opportunistic buyers where we see dislocation between our stock price and our intrinsic valuation. Now, let me conclude with our initial 2022 outlook and guidance. As I mentioned earlier, we did not expect to record any U.S. Regenco sales in the first half of 2022. For U.S. praline, throughout 2021, we observed significant category and competitive pressures. We expect these pressures to accelerate throughout 2022. And now for our 2022 expense guidance. For R&D, we forecast our 2022 R&D expense to be in the range of $2.8 billion to $3 billion. As we highlighted throughout 2021, Critically important development programs are advancing in 2022, including the late-stage randomized studies versus branded comparators for the LAG3-Liptyo combination, BCMA by CD3, NC5 programs, and development expenses to advance next-generation antibodies against COVID-19. For SG&A, we forecast our 2022 SG&A expense to be in the range of $1.65 billion to $1.77 billion. Based on our initial plan, we expect SG&A expenses to be spread evenly across the quarters in 2022. For COGS, we forecast 2022 product growth margin on our percentage of net product sales to be between 90% and 92%. We expect cost of collaboration manufacturing to be in the range of $750 million to $830 million, driven by continued growth in our depiction franchise. And finally, we anticipate our 2022 effective tax rate to be in the range of 13% to 15%. A complete summary of our full-year guidance is available in our press release issued earlier this morning. In conclusion, our core business continues to advance and strengthen. With growth continuing across our existing portfolio and investments in our R&D engine supported by our strong balance sheet, we remain well positioned for sustainable long-term growth.
spk04: Thanks, Bob. Michelle, that concludes our prepared remarks. We'd now like to open up the call for Q&A. With many callers in the queue, we want to ensure that we're able to address as many as possible. We'll answer one question from each caller before moving to the next. Please go ahead, Michelle.
spk12: As a reminder, to ask a question, please press star then 1. If your question has been answered and you'd like to remove yourself from the queue, press the pound key. Our first question comes from Evan Siegerman with BMO. Your line is open.
spk03: Hi, all. Thank you so much for taking my question. You had touched on your solid tumor oncology franchise, specifically the met-by-met program. and MUX16 by CD3 by specifics that we're supposed to get this year. Can you elaborate a little as to kind of what we should be expecting with these data readouts and how that could inform potentially pivotal trials or a registration pass? Thank you very much.
spk11: Yeah, these are both being evaluated in late-stage patients who have essentially failed all existing therapies. And obviously the excitement would be if one saw evidence of convincing patients objective responses that were durable in these settings, and those would certainly inform how we move forward on these. And we've already announced that we've been observing encouraging early signs of efficacy, and we will be elaborating on these and giving the details in these future presentations.
spk04: Great. Thanks. Michelle, can we go to the next caller, please?
spk12: Our next question comes from Carter Gould with Barclays. Your line is open.
spk00: Good morning. Thanks for taking the question. Maybe I'll just take on the elephant in the room. For Len and Marion, I would love to get your thoughts on, as you think about the ILEA franchise in the context of what looks like a very accommodating label on furosemab and their pricing as we think about the implications for your high-dose label and commercial positioning.
spk08: Yeah, I'll let Marion get into the details. But we don't see furosemab as a transformative therapy of any kind, notwithstanding any label. It's very hard to see, when you look at it dispassionately, any scientific evidence for the contribution of ANG2 blockade. You know, people forget... Nobody has a greater interest and would love to see ANG2 blockade being evaluated, given that George and his colleagues were the ones who discovered and cloned ANG2 as the first in the world on that. But there's really no evidence that we can see where you separate it out. So what we're seeing here is a higher dose of furosemab relative to Lucentis. possibly on a molar basis relative to ILEA, we remind everybody that there are a lot of lessons learned here. And one of the biggest lessons is efficacy is super important. But well beyond that is safety. And nothing right now can track the, I don't know, almost 50 million injections that have been given worldwide with ILEA. So we feel pretty good. Competition is always good. Obviously, competition is going to eat into product. We suspect that Ferris Rev may take a lot of its share initially from Lucentis, but we'll see. Mary, you might want to elaborate.
spk05: Thank you, Lynn. Certainly, to give some very early market feedback, the comments that we're getting from key opinion leaders is that they don't see FirstMed to be a product that potentially is a game changer and that the dosing is complex and there are remaining questions on the clinical trial design and, of course, as Len mentioned, safety. More importantly, I'll go back over to ILEA where we certainly are, you know, establishing the product as standard of care and more across indications with great flexibility of dosing, indications, experience, real-world evidence, pre-filled syringe in busy times. So we look forward to strong performance going forward on ILEA, and we're very optimistic about what could be a next-generation product with our own Aflipracept 8-milligram high-dose product if the Phase III data works out.
spk04: Michelle, let's go to the next question.
spk12: Our next question comes from Tyler Van Buren with Cohen. Your line is open.
spk07: Hey, guys. Good morning, and thank you very much for the question. So for your next generation COVID antibody cocktail, it looks like it's, you said it's entering the clinic in the coming months. So was there a slight delay versus the prior Q1 guidance? And you referred to FDA streamlining development of monoclonal antibodies. So can you give us your latest thoughts on how long it might take to get to market? I noticed Bob mentioned that there won't be sales in the first half. So just curious if we could do something in the second half.
spk08: Yeah, George can comment on what he thinks is necessary, but I just want to be clear, I don't think there's any delay, whether we come in just at the end of this quarter or early in the next quarter or thereabouts. You know, it's tough to exactly estimate when we'll start. But we're scaling up and we're roaring forward. George can comment on some of the global and U.S. regulatory considerations and guidances that we know about thus far.
spk11: Yeah, there's not much to add. I mean, we're continuing to discuss with regulators what the program is and what are the abilities, as was done with vaccines, to expedite the development programs compared to what was necessary for the first-generation agents developed using the same platform. So we will update that as we learn more. George, there's some confusion.
spk08: If you could clarify it. Our next-generation antibody work on just Omicron, is there work on all of them?
spk11: As I mentioned in my script, so obviously we have one of the largest collections of antibodies to choose from, and what we do as a variant emerges is we select new candidate antibodies that will work against the new variant, but will also retain their activity against the previous variants of concern. And that's exactly... the candidates that we're advancing right now. They work against Omicron, but they work against Delta. They work against all the other variants before that.
spk08: And anything, any comment on stealth Omicron? Do you think it'll work there too?
spk11: Well, yeah. Obviously, we take all these things into consideration. And so when a new variant that looks like it could be coming along that might be important, we certainly have made sure that the candidates that we're advancing now are going to be active against all of those as well. Great.
spk04: Let's go to the next question.
spk12: Our next question comes from Salveen Richter with Goldman Sachs. Your line is open.
spk13: Good morning. Thanks for taking my question. Could you just speak to the RNAi programs? I think we're going to get first data this year from ALNAPP from that program. And how do you think about, you know, the optimization of delivery to the brain here and what we might see and how the C5 program could be differentiated?
spk11: Okay, so you're asking about the brain and CNS and the APP program, but you're also asking about C5. Okay, so, yeah, with the brain, obviously, as we all know, there have been disappointing results with antibodies that have been delivered to try to decrease APP levels. They work in a fundamentally different way. One of the problems that they cause, they cause this famous... inflammatory syndrome that may complicate activity. So obviously the hope of siRNA programs is they work by a completely different mechanism. They will actually decrease the production of APP and allow it to be cleared by normal mechanisms as opposed to letting it be made continuously at the normal rates and then trying to remove it by artificial mechanisms that they themselves may be toxic, i.e., the antibody efforts. So that's why they may be fundamentally different. Importantly, we're exploring this not only in Alzheimer's disease, as we all know. It's not as if the early results in Alzheimer's disease are going to really address the important endpoints, that is, cognition and efficacy and slowing down cognitive decline and so forth. They're going to be looking at levels of the biomarkers and so forth. That's why we're also excited that we are developing the same exact agent. In some ways, a much more rapidly progressing, though albeit much rarer disease, known as cerebral amyloid angiopathy, or CAA, because there, the ability to both look at the biomarkers, but also, more importantly, look at important efficacy parameters is going to allow us to proceed much faster in much smaller numbers of patients. And therein, we may be, over the next couple of years, able to establish both definitive efficacy, but maybe even get this agent approved in those indications. And that will certainly be quite an advance for the entire field of these types of diseases, and particularly for the first siRNA that's going into these diseases. So we are very excited about these programs, and we have a very large pipeline of other CNS diseases and targets that we are going forward in addressing with El Nylon. So, it's a very important part of our collaborative efforts with them, which also include a large number of targets in terms of genetic targets, genetically validated targets, and diseases in the eye, let alone outside of the eye, such as, for example, in the liver. And that brings us to the C5 that you asked about. So, as we all know, people are taking, you know, single types of approaches to target C5. You know, some people might have an antibody. There's now some other types of approaches and so forth. What we realize is that if we could combine an siRNA with an antibody, we might have really not only Combining the unique advantages of both, but incredible synergies. And what do we mean? Antibodies have the highest effectiveness because essentially they can bring down activity levels almost to zero. But because of the high target load, you have to give these antibodies, and these are all the existing approved antibodies and those that are under investigation by other sponsors, you have to give them relatively large amounts of them and relatively frequently. So antibodies are great, but by themselves, you need to give a lot of antibodies to deal with the high target load. SiRNAs are great at reducing the target load, but they don't get you to really almost zero activity, and that creates problems. We already know that. By putting the two together, you now get the best of both. You reduce the target load, and you allow now a much smaller amount of antibody to control activity, hopefully completely. So there really is tremendous synergy with these. This is the first of its kind that is combining sRNA with antibodies. We think there is very exciting potential for this to deliver best-in-class both efficacy but also convenience in dosing regimen. We're going for convenient subcutaneous self-administration once a month, which would really, I think, be game-changing for the field and for these patients. But we're also moving these programs also to other related indications as well. So we're very excited about this combination approach for C5 and for these types of indications. But once again, just like what we're doing with CNS, just like what we're doing with I, these are really franchising portfolio opportunities. I mean, you can just imagine if combining, and there are so many other settings where this could be very useful, combining the benefits of siRNA and antibodies, and bringing them together could really be game-changing, not only in this area, but in many, many other areas. And who better to do this than bringing together the leading siRNA company and the leading antibody and biologist company, Alnylam and Regeneron. So we're very excited about the individual programs with some of these siRNAs, but also these incredible combination opportunities bringing these two incredible technologies together, taking the advantages of both. Great.
spk04: Michelle, let's go to the next question. Operator, can we go to the next question, please?
spk12: Our next question comes from Lonnie Gal with Alliance Bernstein. Your line is open.
spk02: Good morning, everybody. Thank you for the great result in taking the question. Mine is from Marianne. Can you talk a little bit about the VEGF market? It seems that we've been coming close to a year for better than 10% growth, and I was wondering how much of this is catch-up versus how much of this is just higher natural market growth rate versus what we're expecting? And then can you talk a little bit about the dynamics of what it takes to compete in this market, kind of like how long to get a J code, how long to have contract with different practices, essentially how long will it take a competitor coming online, whether innovative or buy similar, to really be able to effectively compete in that market?
spk05: Sure. Ronnie, happy to take it. And I'm going to take the end of your question first. And I first would say that a competitor or a new entrant to the market's ability to compete is is really going to be based on the differentiation of their product profile, the quality of their studies, and the confidence and enthusiasm that the key opinion leaders have on the product as it comes in. So I do think differentiation matters quite a lot. In the case of ILEA, certainly our growth in the past year has been quite pronounced. We've captured not only the market growth, but we've also seen captured competitive share gain more than any other product, so that our market share today for ILEA is approaching 50 percent of the overall category and 75 percent of the branded category, and we've picked up several share points in the last year in this very large category. Let me go back now to new entrants who are asking about timing of J codes, and that is important. Quality of product, as I mentioned, reflects confidence in how well it performs. but it is a six-month period before a new product receives a permanent J-code. So in that window of time, especially in a product which is buy and bill, there's always the concern on reimbursement. There's not experience, not with the product, but there's also not experience with applying for reimbursement under the J-code. That period of time is six months. And to my earlier comment, product confidence will vary based on profile. I hope I've covered it. most of what you had in that. The only thing I think I probably missed is anti-VEGF category growth going forward. That is a little bit complicated because we're comparing to recovery in the market opposite the COVID period to some extent. However, there is growth of the category because of patient demographics and because of education. You know, I'll give you as an example of of patients who are diagnosed with DME, only about 47, 48% of those patients are treated. And those are those that are diagnosed. There's only, if you took all DME patients that exist, only about 25% of those patients are treated. So there still is tremendous unmet need in the marketplace. And we certainly will work hard through educational initiatives to make sure that we perform very well as we have been on an ongoing basis on all of our indications. So I hope that helps, Ronnie.
spk08: Can I just say one thing, Ronnie, on that, which is that it seems like it's been every single year for the last decade there has been a threat to ILEA that a variety of number of people have predicted would be the next thing to displace ILEA. And along the way, the barriers have changed. And the most important barrier that I think now exists is safety. And that safety, even for a biosimilar, the same product, safety for a new product with purported differences. You know, people have learned that the eye is a very sensitive place. And having given scores of millions of injections of ilea, there's a great deal of confidence out there. I think it's going to take a matter of time beyond J codes and meeting with practices before that level of confidence is significantly displaced.
spk04: Michelle, let's go to the next question, please.
spk12: Our next question comes from Robin Kamaskas with Truist. Your line is open.
spk06: Hi. Robin, is your telephone? Hello. Good morning. Sorry about that. My phone was on mute. This is Nicole on for Robin. Just a really quick question on yesterday's report on the Anacid Bio disclosing the Regeneron exercising option to license an Allocart T. Can you just comment on the move towards Allocart T and why this particular asset?
spk11: I couldn't hear the end of the question. It was a little hard to hear the question. The Anacid. Yeah, but what was the question? Could you repeat the question? Why does that matter?
spk04: What's the importance of it?
spk11: Okay, so, well, as you already referred to it, I mean, this is an advance in the CAR-T space because, obviously, so far, the approved approach and upcoming approaches are all dependent on giving... customized, individualized, autologous CAR T cells. And the results coming from this relatively novel gamma-delta approach, it's the first gamma-delta data in the world, showed that you could give allogeneic cells and get very remarkable, in very small numbers, but very remarkable response rates. And so this would take the customization autologous approach and take it to the autologous, to the non-autologous allogeneic way, which will really, could potentially revolutionize the treatment paradigm here. And so we've been long-term collaborators with Adacet, and we're pretty excited about this allogeneic approach. And so we're investing in it.
spk04: Great. Michelle, let's go to the next question, please.
spk12: Our next question comes from Matthew Harrison with Morgan Stanley. Your line is open.
spk01: Great. Good morning. Thanks for taking the question. I was hoping for one on CoStim. I know we're supposed to get some data this year. Can you just maybe help us think about dosing levels, how you're thinking about safety currently, and just in terms of initial data, what we should expect to see, whether it's just about safety or we should really start to have some idea on efficacy as well? Thanks.
spk11: Yeah, that's a great question. As we all know, this pathway was – explored many years ago now and led to, unfortunately, very dramatic safety concerns to patients, and that sort of killed the field. And so because of those concerns and that we were re-exploring utilization of this very, very powerful co-stimulatory pathway to add to, in combination, other immunotherapies, you know, the FDA appropriately asked us to move very, very slowly. So the first endpoint of most concern was the safety endpoint, of course, first do no harm. And I think that what we've announced is that in our ongoing dose escalation study, it's only been recently that we have achieved what we think are therapeutic dose potential levels. And And now, and we have, I think the thing that we have said publicly is we successfully crossed in terms of getting to these dose levels this very concerning and potentially, you know, game-stopping safety hurdles. And so now that we're at the potentially therapeutic dose levels, we are now hoping to focus on efficacy. And remember, In several of these programs, but for example, our prostate program, we're going in a setting where at least if properly identified, there are essentially no or very rare responses to PD-1 in these types of very carefully characterized prostate patients. I mean, there's been very little hope except for rare subsets of characterized patients that have mutations and so forth. for the PD-1 immunotherapy class. So if we can show essentially almost any responses in these types of very recalcitrant, hard-to-treat patients with PD-1 alone, in our combinations with our COSTIN for prostate cancer, I think there's a real reason to believe that our scientists have successfully figured out a completely novel way of taking advantage of this long-known, very exciting and powerful but dangerous pathway that we may have figured out a way to take advantage of it and done it in a safe manner. So this is what we're hoping to see this year, that now that we are at these levels, we've gotten there without activating these huge safety concerns that were previously seen. Essentially seeing any objective responses in this setting would really be potentially game-changing, and so we're looking forward to being able to tell you about this possibility later this year.
spk04: Operator, we have time for two more questions. Can we start the next one, please?
spk12: Hi, next question comes from Corey Kasimov with J.P. Morgan. Your line is open.
spk09: Hey, good morning, guys. Thanks for taking the question. I was wondering if you could frame expectations for the pending update on your program with Intelia that we're getting here near term. What new might we see relative to last summer's preliminary data disclosure? Thank you.
spk08: Yeah, we don't want to get too far in front of our partner. George's remarks already indicated the kind of things we'll see, but we should leave it up to Intelia to comment beyond what George said about looking at the dose escalation and including the safety and knockdown of it. But Intellia should have the benefit of making some comments.
spk11: But maybe just a couple obvious points. There's not stealing anybody's thunder. But obviously the initial results were incredibly exciting and revolutionary. Obviously the first systemic-based CRISPR therapy. I mean, all this excitement for almost 20 years, Nobel Prizes and all this. I mean, it is incredible that together with our Intellia team, colleagues, I mean, this represents the first ever systemic use of CRISPR to actually modify human genetic gene. But obviously, one of the most important things that one will see is the whole promise of this approach is duration. That is, you are modifying the gene, and hopefully you will never have to treat that patient again, okay? And that's part of the dream and the hope with these genetic cures, and so this is, of course, one important thing that we hope that we'll be seeing from the follow-up data, the duration, which is what is really game-changing. You can permanently cure these patients. That's the theory here by permanently changing their genes, and so the longer you follow them up, the more you can validate the duration of with, of course, the appropriate safety, and continue to keep the dream alive that this whole new approach could really be game-changing for important and appropriate clinical indications.
spk04: Operator, we have time for one quick last question.
spk12: Our last question comes from Mohit Banzal with Wells Fargo. Your line is open.
spk14: Great. Thanks for taking my question, and congrats on the progress. Maybe another one on Farisumab. And given that your competitor also has Lucentis, which is facing bias similar this year, are you seeing any rumblings of, you know, potential bundling or attractive pricing for those both products combined that could be played as a strategy to take on ILEA? And how much does payer versus provider matter in this market? Thank you.
spk05: Sure. So, you know, at a high level, I'll share just and talk about our own businesses. Certainly, you know, we have strong... market understanding and work closely with all of our customers across the market segment. When it comes to how another company might be looking at their pricing or strategy, it's probably best I let them comment. But I appreciate the interest in the category and the question.
spk04: Thanks, everyone. That concludes today's conference call, and thanks for your interest in Regeneron. The IR team and Bob Landry is here to take any questions that you may have. Everyone have a nice day.
spk12: This concludes the program. You may now disconnect.
