What you see on the screen is a rabbit since this is the year of the rabbit. And every year, I doodle with the drawing of the zodiac of the year, animal zodiac of the year. Eisai is like a wild rabbit with animal spirit, and with lecanemab, we will jump. And globally, we would like to bring about benefits. And that is the meaning I wanted to convey in this drawing. Today, I would like to cover these 5 topics. First, business model driven by the article of incorporation, the hhceco model. This is the articles of the incorporation of Eisai. Since 2005, corporate philosophy is included in articles of incorporation. Articles of incorporation is like a constitution for a company. And more than 2/3 majority voting at the AGM or special resolution is required to adopt or change articles of incorporation. Last year, the AGM revision was made to Article 2 of the articles of incorporation, corporate philosophy. What is important is that we go beyond the realm of health care, but a stakeholder, the general public, was added. And secondly, under #2, we use the phrase social good. In these days, there is much talk about the purpose of the company's or social impact. This is also often talked about under the discussion regarding new form of capitalism, and Eisai's version of that is social good. More specifically, we seek to effectively achieve social good in the form of relieving anxiety over health and reducing health disparities. And we seek to achieve this effectively. Thirdly, company's mission. The mission is to increase the satisfaction of patients and the general public. This remains unchanged and to empower people in the daily living and medical domains to realize their fullest life through the -- through an hhc ecosystem based on collaboration with other industries. Over the whole of the lifespan, we would like to engage with the general public, and we would also like to develop ecosystem-like business model to encompass that through collaboration with other industries. And please refer to #1 under 5. This stipulates the content of the business activities, raising awareness of illnesses and providing information and services. Pharmaceutical products and information related to pharmaceutical products were -- have been provided by Eisai. But in addition, we would like to provide information and services utilizing technologies in addition to pharmaceutical technology, and that is stipulated here. Eisai hhceco model is the business model to achieve this. And this is an example for dementia. We will have hhceco model for each disease area. And the first model is to be developed for dementia. But oncology is an area we have been making efforts over many years, including for breast cancer and endometrial cancer. And in gynecological cancer, hhceco model can be developed. We believe we have sufficient capability to develop hhceco model for gynecological cancers. Currently, we are in the process of developing hhceco model for dementia. At the outermost rim this slide, people living with Alzheimer's, families, caregivers, health care providers, peers, government, shareholders and employees are the stakeholders to whom we will be delivering social impact and value. And in return, as shown at the very bottom, there is a potential of funding through sustainable financing with social impact targets as KPIs. This can be one form of the reward for the impact that we deliver. Funding and financing cost for Eisai will be lower in comparison to the situation where no such impact is delivered. Inside of this ecosystem and inside blue dotted line, that is hhceco model. In the very important base of that is data. For example, genome data for disease or our proprietary data, meaning data from clinical studies and real-world data and personal health record data, these data are the very important premise of our hhceco model. These data will be input into the model to create value. And R&D will play a very important role in creating value. In addition to the conventional R&D or, rather, we are shifting in a major way from conventional R&D, we are now looking at disease as a disease continuum. Dementia starts from preclinical condition to severe condition. And in case of cancer, there is precancerous condition to metastatic disease. There are various stages within a disease. And for this disease continuum, we would like to apply human biology, which is becoming more and more clear. There is a better understanding of human biology, and based on that understanding, we will engage in drug discovery. This is what we call DHPL, deep human biology learning structure. And this will be playing a central role in value creation within the ecosystem. And from that, their solutions will be emerging, as shown in the top part, real-world medicine -- real medicine or prediction of the progression of the disease, et cetera. And these solutions can be provided to the people in various stages. That is the hhceco model. And purple circles around are partners. In case of industry collaboration, insurance industry for dementia insurance and it is said that JPY 160 trillion is the asset owned by dementia patients, and we can collaborate with the financial services industry to address that issue and connected car program to be developed with the automobile industry collaborating partners to ensure safe driving for elderly people. And to create a society that is safe and secure, it is important to work with local governments as shown in inclusion bubble. And we are also collaborating with academia and the start-ups. This is indispensable. In relation to data, general data, public groups, we are working together or monitoring PHR partners, are also partners for collaboration in this hhceco model. That is the overall picture of this model. This is a busy chart, and I will briefly walk through -- walk you through this. And this is the dementia version of ecosystem. At the very top shows the stage. It starts from aging, and there is a high-risk stage and preparation for care. Up to that stage, there are various stages. In each of these stages, people have various anxieties. In hhc project -- through hhc projects, we have a deep understanding of what anxieties people have. And anxieties include anxiety about one's health condition and what solutions can we offer. People may not be aware of the condition called dementia, or even people at high risk may hesitate to go to the hospital and may have fear of being diagnosed as having dementia. There are many people who have such anxieties. We need to provide solution to address those anxieties. Dementia is now becoming a disease -- or dementia has become a disease that can be treated, and we have to communicate that and cognitive function checking, for example, with NouKNOW should be made widely available by working with our partners. Those are included in our solutions from medical consultation to treatment to evaluation and monitoring. In case of medical consultation, clinical diagnosis, no matter where a person may live, it should be possible to seek consultation and diagnosis. And A-beta diagnosis environment should be better established in communities, and solution is to provide an environment where consultation and clinical diagnosis are possible wherever one lives. And in health care sector and otherwise, what is possible to seek, that can become a very important part of the solution. PET equipment may not be available in a nearby facility, but if in a different specialized clinic, it may be available. And where are -- specialists provide practicing and how can these specialists work together with family doctors, and that is what we are trying to address in our solutions. As for development of inclusive societies, there are health checkups by local governments, and NouKNOW can be used in ordinary health checkup to identify people at high risk. And people at high risk can be referred to medical institutions in the community. We are implementing these solutions. And one of the key in the solution packages is the very bottom row of boxes. Risk prediction AI and treatment-effective AI are some of the things that are mentioned here. And based on our proprietary clinical trial data and proprietary cohort data based on that data, AI algorithm is developed. And in a personalized fashion, prediction can be made for each individual. Within the solution packages, this is a part where we have the most proprietary value. In addition, on the left side, there is a box called Click-Karte with a smartphone camera. If health check-up results are photographed in a clearly organized way, information can be organized and be presented in easy-to-grasp fashion. ePRO, electronic patient-reported outcomes, on the right side between clinical visits, the daily experience of the patients can be input into an app by patient or family to be shared with medical providers. And we -- it is known that by using ePRO, there is a better -- there is an improvement of treatment effect. Within such ecosystem, it will be indispensable to use digital technology. This is digital model called Yin Fa Tong, which is used in China. This is a collaboration with Jingdong Health. On the left side, you see screens of a smartphone. There are more than 94,000 users who are registered as app users. And this is for online treatment, online health platform for the medical treatment. Over 4,800 physicians, including specialists and neurologists, are registered, and users are able to choose a physician and can seek medical consultation online. Last year, in 1 year, over 2,000 times this service was used. In a very vast country of China, this will enable providing dementia medical consultation in a uniform fashion, eliminating regional disparities. This is an example from Thailand. We would like to expand lecanemab to Asian countries. When lecanemab is launched in Asian countries, naturally, an important question is who will pay for that cost. And as one solution, here, we are tying up with Thai Life Insurance. Thai Life is the second biggest life insurer in Thailand and as noted here, insurance product that covers expenses for the treatment including costs for drugs. If insurance subscribers are diagnosed with mild to moderate AD, this product was developed. And with this product, a part of the cost of lecanemab, we believe, can be covered. And within the same group of Thai Life Insurance, [ there ] the bank and this bank is considering dementia alone at a favorable rate. By tying up with these financial service players, we are -- we believe we can provide a funding assistance to middle to lower income segments, and that will be a very important part of our work in hhc ecosystem. Now I would like to turn to the next topic, which is we like to aim to replicate LEQEMBI's success. As you may have known very well, LEQEMBI demonstrated its remarkable p values, quite astonishing results. So we believe that this is a very powerful innovation derived from Japan, which will create a new chapter in the history of drug discovery. So why was it possible in the first place? These are the 4 patterns of success, we believe. First one is, in drug discovery, you needed to have hypothesis as the basis for creating new drugs. That is very important. If you have the wrong hypothesis, you are not able to create good drugs. So the very rough drug profile will result. So having the right hypothesis is absolute necessary condition for success. As I said earlier, this hypothesis needs to be built based upon human information. The most human information is available in academia, so through collaboration with academia to establish this right hypothesis, which I believe is going to be the first condition to make success. The second condition is what we will be able to obtain from Phase II study. Phase II study is in between Phase I and Phase III. Therefore, people may usually think that you would like to finish this study quickly in order to transition into Phase III or pivotal study. So that is the mentality of pharma company. But in this LEQEMBI case, we had to take 6 years for Phase II study. In this phase, what kind of target population will be most effective? MCI due to AD and mild AD, early AD was obtained as the right target as a result. And dose 10 milligram per kilogram biweekly with no titration, this dosing schedule was found to be most effective. And for end point, CDR-SB was used, but originally, it was planned to conduct for 12 months. However, rather than that, we decided to opt for 18 months for a valuation of CDR-SB. That is derived from the results of the Phase II study targets. Dosage and end point all were rightly set up and identified from this Phase II, which I believe is another major factor for making the LEQEMBI project a success. Third one is robust ability to conduct clinical research. First one under this is clin pharm or clinical pharmacology. As you know, this includes pharmacokinetics, pharmacodynamics. Simulation is relevant to this. In case of lecanemab, utilizing these technologies, efficacy depends or correlated to CRH, and area is correlated with Cmax. These were found in early course. Therefore, this was very effective and useful for setting the right dosage and maintenance dose, which is being studied with less frequent dosing to maintain the efficacy of the treatment. So in development of the maintenance dose, this clin pharm capability has been quite useful. So this is a very important aspect. Second one here is sophisticated statistics. As I said, in this Phase II, 5 doses were compared to placebo. During this period, which was 18 months, 16 -- as many as 16 interim analyses were conducted. Therefore, almost every month, IA was conducted. Every time, the new -- next cohort is where patients are assigned to the area showing you the best efficacy. That was the design. This required a very advanced, sophisticated statistical technique. Reaching a Phase III study is simply the 2-arm comparison with 1 dose. 1,800 patients were enrolled. So this is a very large-scale study with a very sophisticated statistical technique. So I think that this very powerful statistical capability was very important. And lastly, the central clinical trial is mentioned here because this period of this study matched the period where the COVID-19 infection spread, therefore, patients could not come to medical institutions. Diagnosis or visiting have to be done remote. And remote cognitive assessment and safety should be monitored remotely. And also, administration was done. The health care providers visited the homes or places of the patient to provide a treatment. So that was the key in the success of the clinical research going forward and lessening the burden of the patients in order to carry out clinical research. I think this is going to be a very powerful factor. Number four, the value of the drug in this particular society needs to be quantified and demonstrated based upon the value pricing we've set. So we implement the value-based pricing. So we needed to explain for that with high transparency. By doing so, the drug or a therapy would be more acceptable in the society. So I would like to raise these 4 as the patterns of success in drug discovery. And the first source of such success is derived from the hypothesis for drug discovery and with academia. And the patients do not come to medical -- to pharmaceutical companies. They come to medical institutions, particularly university-affiliated hospitals. Therefore, frontline of human biology is not in pharma companies. That resides in academia. Therefore, the most human biology data is accumulated in academia. So in order to create a human biology-based hypothesis, we needed to collaborate secur1ely with academia. There is no doubt about that. So if you just knock on the door, you are not able to get collaboration from them easily. With these 3 colleges and universities, we have built very deep and sound long-term collaboration relationship through various activities, in the middle, University College in London, which is located in London, where a neurology research is conducted jointly with us over 10 years. In 1980s, on the campus of UCL, we established London-based research institute of Eisai. So that was the start for collaboration, which lasted very long. U.K. dementia research, 7 university or college consortium is established in the U.K. and UCL has been playing as -- a role as a hub. An antibody research was derived from the research conducted at the UCL. To your left, EKID is the collaboration with Keio University, which lasts over -- for 10 years and funded by AMED, and it is in its sixth year. As you can see here, Keio University has a centenarian cohort, 100, 110, 120 years old patients or peoples are being monitored. Then at 120 years old but still healthy and ApoE4 carriers but not had an onset of the dementia, why can it be possible? Based upon the multi-omics research, they are studying such cohort. And the omics data here are for the entire body such as intestinal flora and also oral flora of bacteria and the details and also the underlying disease such as complications, and all are included in the omics data. Therefore, not simply about the neurodegeneration information but rather more deeper, for example, like information about the robustness of the brain is included in the data. It may lead to the -- a clue for the discovery. There are 3 milestones. And first milestone has been cleared, and that is related to the pumping of the removal of the waste from the brain. And this was the trigger for creating the new drugs. And that is -- the first barrier was -- but the ultimate goal is to reactivate the neurons. So that is the ultimate goal. And iPS and organoid of the brain, the cutting-edge technologies, they have such technologies on a world-class level. To your right, WashU, meaning Washington University in St. Louis. As you are aware, they have a DIAN. The hereditary Alzheimer's cohort is being managed by this research group. And also the anti-tau antibodies are being tried. And the cutting-edge biomarker is being researched here. We have exchanged between Eisai's research as well as their research. They are wearing 2 hats as our researchers as well as they're researchers at the university. Such anti-MTBR-tau antibody, E2814, which is described on the right-hand side and what I'd like to say is that LEQEMBI's origin hypothesis, MOA and target population, so E2814 is following almost a path towards winning, which was followed by LEQEMBI. First, regarding the origin. At UCL, which I disclosed earlier, the core of the tau aggregation is found to be MTBR-tau. That was discovered. Therefore, this is the propagation species of tau, MTBR-tau. If you are able to capture them in the extracellular space and then will be able to remove them in order to prevent the propagation of taus, and that was found at the UCL. This anti-tau antibody, particularly binding to these regions called R2 and R4 specifically, this antibody was created. At the same time, at Washington University, hereditary AD patients' CSF, MTBR-tau was found to be increased at a very early stage. Such human biology evidence was discovered. This hypothesis based upon the tau propagation specie, MTBR-tau, if that is removed and then aggregation, accumulation of tau can be prevented. Therefore, it is thought to be able to provide a new therapy for AD. On the right-hand side, although this is very busy, but this contains very important information and this is taken from [ CU ], an AD cadaver brain. And then tau species profile was conducted. As you see in the right, MTBR region is indicated. And please look at R2 and R4, 299 and 354, a normal and a mild and a severe. Compared in severe AD, these have been expressed very highly, so not dependent on the dose, but this is correlated to the progression of the disease phases. So very powerful evidence was obtained. So we are very -- we have very high confidence in this MOA. Currently, DIAD program -- with DIAD program, this anti-tau antibody, lecanemab is utilized for a treatment of AD and a Phase II [ SR3 ] study is ongoing. And for sporadic AD patients, of course, they have similar symptoms. Therefore, we would like to apply this technology to such patients as well. Now the pipeline that is shown here, on the horizontal axis, you can see all phases of the disease. And on the vertical axis, you can have all pathophysiology, ADNI -- or ADIN, covering all the phases stages of the disease and all pathophysiology factors. We are preparing the development of these treatments. So we believe that we have the world's best and comprehensive pipeline. Pricing based on societal value or value-based pricing, as shown here, the thinking illustrated here is that regarding lecanemab, when we set price for lecanemab in each country, we would like to apply this as common way of thinking or common logic. First, every business should generate a social impact. The current administration advocates new form of capitalism, and I believe this is in line with that concept. And we have to enhance the understanding of stakeholders of this. And in order to enhance understanding, social impact must be quantified. And the quantification is done using disease model called AD ACE model. It is now possible to quantify and by inputting various data into this model, lecanemab annual value or yearly value can be calculated. And our value is allocated to public as well as private stakeholders. As public stakeholders, we have people living with the disease and various other stakeholders, including governments and private stakeholders, are Eisai shareholders and employees. To all of the stakeholders, to deliver value is important. In the American society, the -- out of the value generated by lecanemab, 60% will be returned to the public stakeholders, and 40% is to be allocated to private stakeholders. This is a 60-40 split. And this split can be different from country to country. And this is quite natural. In lower-income countries or in countries where health care system or insurance systems are underdeveloped, public allocation should be at a higher percentage. In case of our [indiscernible] drug deck tablet, this is a public return of 100 since it is priced at 0. And as for the value that is allocated to the private stakeholders, it is not that it will merely be consumed, but it will be reinvested in future research and development and for the inclusive communities. I discussed this in January press conference, and I would like to review this once again. In the U.S. society, the yearly value of lecanemab is estimated at $37,600 per person, and the price set in the United States per person per year is $26,500. Value and price are different. And the value was estimated using this formula. Very briefly, the numerator part, 0.64 multiplied by $200,000 means that the health -- the total sum of health delivered to U.S. society by lecanemab. What is the additional gain of total sum of health in monetary value? That is represented by this. And 3.6 is QALY, quality adjusted life year. After receiving LEQEMBI, the years lived by the patient is multiplied by indicator, which represents quality of life. Total sum of health, I think, is the most appropriate way to describe this. And as for $200,000 in the U.S. society, if there is complete freedom from AD, how much is one willing to pay? Willingness to pay and around $200,000 is typically or oftentimes used as the amount for willingness to pay. So this can also mean price for 1 QALY. And it increases by 0.64. And if you multiply that with $200,000, we can come up with a value that is delivered by LEQEMBI and $7,415 is how much saving there is in medical cost and long-term nursing care costs and family burden and hospitalization or institutionalization costs. This is the sum of the offset cost or cost that is saved. And this is all represented in present value. And to analyze this, 3.6 years is the denominator or time on treatment is the denominator to arrive at annual value, which is $37,600. 40% of this is to be allocated to Eisai shareholders and employees. And that is shown below. First, $37,600 and the time span of 10 years is used to calculate the price. In 10 years, in the U.S. society, how much value in total will be brought about lecanemab? So $37,600 multiplied by a number of patients who will be receiving LEQEMBI in 10 years, then we will be able to have the value in 10 years. And 40% of that will be net sales to be allocated to private stakeholders. And if that is divided by the cumulative number of patients in 10 years, then there will be a net price for each person. But this net price will include both the original price as well as price during the maintenance dose phase. Maintenance dose currently is assumed to be monthly, which means the price will be half. When adjusted for that, the -- we can derive USD 26,500 in the initial stage before maintenance phase. And this is not exactly 60% to 40%. But in 10 years, in maintenance phase, since price will come down, $26,500 will decline. And therefore, over 10-year period, the ratio will be 60% to 40%. In Japan as well, we would like to have a same discussion in there in as transparent as possible fashion. And as a premise to that, we have to look up the condition in Japan shown in numbers here. On the left side, there is medical cost and public long-term care insurance finance and how much impact is coming from AD or how much AD is consuming medical cost and long-term care insurance finance. In case of medical cost, it's 2.5%. But as for long-term care insurance, about 50% is spent on caring for AD. It shows how much AD is impacting society as a burden and in particular, in long-term care. On the right side, it shows that -- how medical costs and long-term care costs increase in the following stages. In case of medical cost, it will be about double in severity in comparison to MCI. But what is surprising is that from MCI to severity, long-term care cost increases by about tenfold. Lecanemab, according to the current clinical data, is understood by specialists and researchers to slow the progression of disease by about 3 years. What this means is that in the former stage or in the current stage, patients can remain for 3 additional years. In these bar graphs on the right side, rather than shifting to the right side, it will remain on the left side. And that effectiveness will be more pronounced in long-term care cost. That is the value of LEQEMBI. And value-based pricing. In the context of value-based pricing, I believe that the larger effect -- larger savings effect of long-term care cost should be properly reflected in pricing calculation. I believe that, that is necessary. And that is the basis of the concept of value-based pricing. AD ACE model, that was applied in the U.S. If that is applied in Japan, that is being considered, and this is more or less complete. And jointly with academia, we are preparing to submit a paper. We expect the paper to be published in May. Naturally, this will include that the cost of QALY is different. And the willingness to pay for 1 year free of AD, that will also be different between Japan and the United States. And the cost savings will also be very different between the 2 countries. And therefore, the results is expected to be different from the U.S. result, but a similar argument is possible to be applied in Japan. And value-based pricing as a pricing approach is possible. And the current Prime Minister evaluated highly LEQEMBI as innovation coming out from Japan. And as a worldwide innovation and a new form of capitalism, it is said that companies that bring about social impact should be rewarded. In the form of reward for pharmaceutical companies, it should be reward that is reflected in the pricing for pharmaceutical products. And that is why I wanted to explain this. And if such a pricing approach is adopted by Japan, that will very much encourage innovation in life science sector. And I believe that it will also help break the sense of stagnation in pharmaceutical industry in Japan. Let me report to you on the update about LEQEMBI. First, the submissions and review processes are being accelerated. On January 6, we received the AA from FDA in the United States. We submitted for the approval, and that was just accepted on March 3. And also this was disseminated as priority review. And PDUFA action date is set for July 6, therefore, a little less than 4 months away from today. In Japan as well, on the 16th of January, we filed submission. And immediately after that, this was designated as a priority review. And in Europe, we have completed the submission. In China, in February from NMPA, we have notified of the priority review designation. Therefore, in major agencies, we believe that review process is being accelerated and steadily ongoing. Now in the United States, coverage by Medicare in the United States, the status of this is very important. And the coverage is managed by a government body called the Center for Medicare & Medicaid Services, CMS. With CMS, there have been various advocacy activities. More recently, from Congress, letter was sent. That is shown here. A group of 74 Congress members signed a letter regarding the CED requirements designated by CMS. They asked for a review of this for providing the early and broader coverage for lecanemab is requested in the letter. And the similar contents were written in a letter from 20 senators' signature, and that was sent out on the 17th of February. Now this is quite a busy slide, but with CMS, we have been cooperating and communicating with them. Now the position -- current position of the CMS, in our view, is as follows. Actually, CMS responded, too, in a letter to Alzheimer's Association in the U.S. As you know, national coverage determination, which was announced last year, that was the decision made last year by CMS for the entire class of monoclonal antibodies against amyloid, and this decision will stay unchanged. But when it comes to individual-specific antibodies, out of which, if one is granted full approval from FDA, then immediately after that, coverage with evidence development, or CED, there is such a criteria. But under this criteria, the flexible application will be considered in order to provide a broader coverage. That was the statement issued. So what is important here is under CED, at the time of NCD last year, the CED coverage is to be relieved. There were 3 questions to be answered in order to release -- relieve these requirements under CED. So there are 3 questions. The first one is does the anti-amyloid mAb, in this case, lecanemab, does this improve health outcomes like slowing the decline of cognition and function for patients in broader community practice? For this question, with the data from Clarity AD, globally utilized CDR-SB, which covers both cognitive and day-to-day functional scale, this is comprehensive indicator, and 27% slowing of the decline was demonstrated with the overwhelmingly statistically significant difference. And the overall activity, ADCS MCI-ADL evaluation by caregivers and a 37% slowing of the decline with statistical significance difference. And also QOL measures of EQ-5D-5L and QOL-AD, 49% less decline and 56% less decline were observed. Very clear difference was observed in the difference against placebo. And in Clarity AD study, in patients who had a broad range of comorbidities and comedications and diverse ratio and ethnic elderly patient population that generally reflected that of the U.S. Medicare population, which covers people over 65 years old, therefore, we believe that we are able to answer this question 1 perfectly. Question #2 is do benefits and harms such as brain hemorrhage and edema associated with this drug depend on characteristics of patients, treating clinicians and settings. As for benefits, in all prespecified subgroups, so based upon the confirmation in advance with FDA subclasses, the stages of disease, MCI or mild AD and ApoE4 status, presence or absence of concomitant approved AD symptomatic medication region of America or Asia and so forth. Overall, these subclasses, we have been able to demonstrate consistent data for benefits. As for harms, infusion-related reactions were most common adverse events, but this was observed across all the subclasses. However, ARIA-E and ARIA-H were less common in ApoE4 noncarriers versus carriers. And comparing ApoE4 homozygous against ApoE4 heterozygous carriers, higher frequency was observed in homozygous group. Therefore, harm's information based upon the demographics and attributes of the patients were also available. Therefore, we are able to answer this question. And question 3, how do the benefits and harms change over time? For benefits, based on the CDR-SB, please recall the gap widening over the period of 18 months showing the disease-modifying effect. Therefore, benefits can increase or remain stable. When it comes to harms, after 3 months of administration, harms decreased and then returned to baseline risk. Therefore, for this question #3, we believe we are able to answer perfectly. As you see, at the very bottom is a belief that the clinical study data of LEQEMBI can fully answer the 3 questions, so-called high level of evidence touted by CMS. We believe that our answers will qualify for that. Therefore, at the time of obtaining approval, the Medicare coverage will be flexibly and broadly granted. That is our expectation. And another aspect is about the outlook for the amyloid diagnosis. I would like to give you a brief overview. In the United States as well as Japan, capacity for PET test itself over the past 3 years have been improved. We believe that this capacity is going to be improved in the coming 3 years. But the challenge here is to cover such testing under insurance in the U.S. and Japan as well. PET and the CSF test as well are not yet covered by ample insurance coverage. But in our communication with authorities, at the time of the therapies being approved, PET/CSF to be covered under the insurance, I believe that, that is what the regulatory authorities are considering. Therefore, of the coverage situation at the time of getting approval for lecanemab will be realized. That is our expectation. On the right side, you can find the blood-based biomarker status in the U.S. and Japan. There are several -- more than 2 blood-based biomarker technologies that have been approved. So for the time being, blood-based biomarkers will become available in use in real world. Therefore, using this technology for screening and then will allow us to accumulate data. So for the use of this technology in the confirmation of the amyloid beta or a definitive diagnosis and in blood-based biomarker or BBB shall be utilized. If that situation is realized and data will be accumulated, so by 2025, I believe that the likelihood of having such situation is very high. So now demography. Demographics showing the prevalence and people potentially treated with AD-DMT are described here. Please look at the pie chart or circles. The first population, the largest one, which shows the prevalence of early AD in combination of MCI due to AD and mild AD, which is the indication of lecanemab, which is shown in the outer circle, that is the total prevalence of early AD. As I said earlier, some people may want to seek the consultation by medical institution, so they have to visit first hospitals. So not reaching the stage of using PET or CSF, the CDR will be used for dementia screening, showing the suspect of the early AD. So that diagnosis is necessary. And then after that, the physician will tell the patients to go through the amyloid beta test in Population 3. And in Population 4, they will find that they are -- have positive amyloid beta, and then they will consult with attending physician. And the physician will introduce this amyloid -- AD-DMT. And would you like to have this treatment or not? And then they will reach number five as the population-eligible patient or treated with AD-DMT, so number one, prevalence; and number five, population is AA, the eligible patients. So at last, the patients will reach this step or number five. Going through these steps, if you turn to the bar graph in the middle, currently, the patients going through 1 through 5 steps and then the AD-DMT patients or patients treated with AD-DMT is quite a small fraction of the total prevalence, so the number of eligible patients accounts for only 0.01% or 0.02% of the total prevalence of early AD. Yellow portion here is going to be expanded, of course, when people's awareness is enhanced about the disease and then seeking the medical consultation from 2025 onward when blood-based biomarkers will become available for confirmation. And then Population 3 or 4 will be done -- will be expanded because they can seek such testing more easily. And in 2030 and 2032, I believe that the number of people, patients treated with AD-DMT will increase as such, so accounting for about 1.2%. But in Japan or the United States, where environment of health care is more advanced, and I believe that the number ratio will be further increased. On the right, you can find the prevalence by region. And clearly, Latin America, Asia and China combined, accounting for 70% of the total prevalence. So for the long run, in Asia, Latin America and China, this treatment -- so how access to this therapy can be enhanced is going to be a very important key. I have final 3 slides to show future scenarios. First, revenue simulation toward fiscal 2032 for the next 10 years. The red part is LEQEMBI. Blue is Lenvima. Yellow are -- is new potential products -- others including new potential products. As for LEQEMBI, around 2025, blood-based biomarker expansion is expected. And since around that time, we expect a rapid increase, and we'll reach about JPY 1 trillion in 2028. We will continue to grow. As for Lenvima -- correction, JPY 1 trillion to be reached by LEQEMBI by fiscal 2030. Lenvima may reach peak sales in fiscal 2025. For HCC, RCC, we see strong growth from Lenvima. LEAP studies -- 12 LEAP studies are also underway. And that contribution to growth is also taken into account here. As for new potential products, earlier mentioned, tau antibody E2814 is included. And in oncology, we have MORAb-202. This is a product where we are collaborating with Merck and the CBP/beta-catenin inhibitor E7386 are expected to contribute. Two final slides, management's intention. Eisai is building an ecosystem for each disease that supports and encompasses the people's entire process from healthy state to high risk, onset treatment, follow-up, prognosis by playing the role of a producer. hhceco will be enhanced through repeated mutual interactions between data and solutions. Eisai is a corporate entity that achieves social impact through its business of creating data and providing solutions. That is the clear intention of the management. This is the final slide. You may wonder what this is. Actually, this is where the headquarters in the U.S. of Eisai is located. It is in New Jersey. Last year, we relocated to New Jersey. It's an 11-story building. And at the top-most floor, there is my office. And from my office, we are able to see Manhattan. And for some reason, I'm very motivated to work more and -- by looking at this view. And that is why I included this photograph. And this slide is the new chapter for Eisai hhceco model has started by LEQEMBI. And with that, I would like to conclude. Thank you for your attention.

This is Yamaguchi with Citi. My first question is about Page 25 regarding this diagram about LEQEMBI. Now in FY 2025 onward, there will be an increase. And toward 2032, where you expect to see JPY 1 trillion level, I have 2 -- 1 question. And in 2025, when there will be a turning point in the revenue, as you said, blood-based biomarker technology will become available. That's why you think that there will be a jump. And JPY 1 trillion in 2022, of course, you cannot tell the global average drug price. But JPY 300,000 to JPY 400,000 will be utilized. That means that the 10% penetration from the eligible patients. And I think you said the 3 million, therefore, 0.3 million, 0.4 million, so that will be used for the price calculation, and the penetration will be estimated as the 10%. So what is the ground for estimating that there will be further increase from that? Could you please give us your take?

Haruo Naito

#5

Your first question is, as you rightly pointed out. BBB will become available for the use in a confirmation. We believe that the BBB technology will start to play an important role. So there will be a boost. And in 2030 -- FY 2030, the global brand lead is here, so I'd like to let him explain.

Hideki Toyosaki

executive
#6

Thank you very much. I am in charge of global brand lead of LEQEMBI. My name is Toyosaki. I am stationed in the U.S. now. Regarding this simulation of the revenue, in FY 2030, revenue is expected to reach JPY 1 trillion. How we estimated this number? Let me explain. First, the origin is the AD-DMT, the eligible patients, and this number is used as the start. In 2030, as I said earlier, AD-DMT-eligible patients will reach about 2.5 million. And for AD-DMT, there will be other drugs than LEQEMBI will be launched. So therefore, we have taken into account the market share. For us, LEQEMBI will obtain the largest share of the market of AD-DMT. We are confident. So we have considered a certain share of the market in here. And out of which in -- throughout the year and then a number of patients to be treated is estimated for LEQEMBI. For a certain period of time, that LEQEMBI treatment will be continued. So during the treatment period, dropout rate or discontinuation rate considered in order to calculate the patients to be treated. So for the current year, the new patients will be added, and then the number of patients treated with LEQEMBI is estimated for the year. So in 2030, globally, we'll reach about 0.9 million. So that is our estimate. As you said, the pricing in the United States per person, year to $26,500. But because of the introduction of the monthly regimen of the maintenance and the maintenance period, this price will be halved. And currently, SC, subcutaneous formulation is being developed and which may be priced differently. And for prices other than U.S., which is not determined yet but in addition to the medical value and the social value will be added and therapy's value and affordability for patients and also health care system's sustainability in each different country is factored in, in setting this price. So as I said, AD-DMT-eligible patients, are the starting point for calculating the simulation of the revenue for LEQEMBI. We have taken a conservative view in China and in Asia and globally, around 2030, this LEQEMBI is expected to reach JPY 1 trillion in revenue. We believe that there is such a sufficient likelihood.

My next question is simple. For your company, you have shown us various numbers. From next fiscal year onward, on the ground, marketing costs in the United States and how many MRs or sales reps will be rolled out or Biogen as a partner, I don't think that you have mentioned anywhere in this slide deck this time. But what about the partnership with Biogen? Well, in the near-future strategies of the marketing in the United States, do you have any comments you're able to make?

Thank you for the question. This is Ivan Cheung. As of this moment, we are at the first stage of the launch under accelerated approval. And as you know well, our primary goal is to get the patient journey and the health system readiness in place so that when a second stage of launch, which is post-traditional approval and post-CMS reimbursement, then the full launch will be ready. At this moment, in the United States at the current stage, Eisai is taking the lead with the launch with support from Biogen of course. And at the full launch stage, Eisai will continue to play the role leading the launch with Biogen's support. As of this moment in the United States across all the functions, meaning sales and marketing, medical, market access, government affairs, all the key functions together, we have over 150 people dedicating to getting this stage of the launch in shape. And at the next stage, at the full launch stage, of course, we will ramp up the number of individuals dedicating to the full launch of LEQEMBI because we are obviously, as you heard from CEO Naito, are optimistic about the traditional approval by the FDA and the granting of our broader access by the CMS.

Motoya Kohtani

#13

I'm Kohtani from Nomura Securities. I have 2 questions. And the first, Mr. Naito, CEO, I have a simple question. Lecanemab, A-beta antibody, you had a CLARITY AD study where you had very strong results. And this is carried in New England Journal of Medicine. And as noted in one of your slides, U.S. Congress members are signing letters asking for coverage, and scientists also signed a letter, 270 scientists signed a letter supporting LEQEMBI and with blood testing. On the other hand, there is also a progress, including a blood-based biomarker by Sysmex. And I think this is the first time that a drug as well as diagnosis are led by Japanese companies. However, your share price is not reacting to this much. There should be strong expectations given this situation. But why is stock price not reacting?

Haruo Naito

executive
#14

I am certain that stock price will rise. In the past, through PR, IR, every time we carryout events, we communicate information. And we have been communicating positive information, including the latest communication regarding a priority decision by FDA and lecanemab certainty and potential. With respect to that, there is no negative information. Looking into the future, we do not expect bad news. At least as far as I can see, I do not expect any bad news. And the advisory committee under FDA is also welcome. In a transparent fashion, a discussion can take place, and data can be acknowledged by the advisory committee. And we positively welcome this because we think that this will lead to increased awareness of LEQEMBI. And most likely, we believe that the CMS will be responding in a way that we expect. So I believe that we are in very good condition. And we are having a very good journey at a cruise speed. So I'm very certain that market will evaluate this.

Motoya Kohtani

#15

Second question is on Page 25. This is about the yellow part. I believe this is increasing from '28 to 2030 because of tau antibody E2814 and since this is going to be likely an orphan drug and may be priced higher to be given to DIAD-targeted population. But yesterday, you've mentioned that there will be a study for sporadic Alzheimer's patients. And then will this product be considered an orphan drug? And can this be priced at high price? If a DIAD is successful in sporadic as well, it can be considered that it will be successful. And as for tauopathy MTBR, different types of dementia involving base -- cerebral part and other types of dementia. Are you going to look into developing this product for different types of dementia?

Unknown Attendee

attendee
#16

Ivan Cheung will address the question.

Ivan Cheung

executive
#17

Thank you very much to your question. I believe there are 2 parts to your question. With regard to the first part, you are correct. In addition to studying E2814 in the DIAD population, we will also study E2814 in the, of course, much larger sporadic AD population because we believe E2814 is specifically designed for Alzheimer's disease. As you see on this slide, on Slide 11 right now, as we disclosed previously, we -- in addition to the DIAN-TU Phase II/III study, we are also ramping up the Phase Ib/IIa study also in DIAD subjects, which we will read out important biomarker information this year in terms of early tau pathology biomarkers, late tau pathology biomarkers ranging from tau PET to various species of CSF and plasma tau biomarkers. These information will be very important for us to design the Phase II/III registrational study in sporadic AD in terms of the right dose and more importantly, the right population. So this is the goal for E2814. To your question about orphan drug, now in sporadic AD, of course, this will not be an orphan drug. DIAD, of course, is orphan drug, but sporadic AD is not. And from a pricing perspective, similar to what you heard from CEO Naito about how we are pricing LEQEMBI, same concept we will apply. What is the societal value for E2814? How much we're going to give back to the society and how we're going to price E2814 considering other factors such as health system sustainability and patient affordability? Now to your second -- the second part of your question with regard to other dementia types, as I mentioned earlier, E2814, as you heard from our CEO Naito, the mechanism, this is very specific to catching the propagation of tau seeds from cell to cell in Alzheimer's disease brain. We believe this is important because as you look at other anti-tau antibodies being studied by other companies, studying those more general anti-tau antibodies without being disease specific, meaning applying that across different disease areas, may not be as effective and efficient as E2814. So we believe, given how this is specifically designed for Alzheimer's disease from the early collaboration with UCL, we are going to be focusing in the Alzheimer's disease space first and foremost, including the synergistic complementary approach in combination with LEQEMBI. Thank you.

Motoya Kohtani

Can I just confirm, you said that you will show biomarkers on tau CSF and also tau PET, right? That will be shown this year and that will probably indicate the engagement of this drug on the disease? Correct?

Ivan Cheung

#19

That's the goal -- yes, that's the goal for this year. Not only engagement. We will also have biomarker results that we believe are surrogate for efficacy. That's our goal this year, both target engagement and efficacy surrogates.

Next question is from the person in the front row, please.

Seiji Wakao

analyst
#21

My name is Wakao. I am from JPMorgan. With the presentation, I have been able to understand clearly your ecosystem as well as the R&D strategy. And you said that you are expecting to see the rise in stock price. You seem to be confident. And going forward, as you've said, ADCOMS and donanemab results will become available. So for both of these, I would like to seek your opinion and a take from CEO. And ADCOM, I think you have touched upon briefly. You said that you are very confident. But in the first place, ADCOM will be held. What is the ground for having such ADCOM? What was the cause for them to determine -- decided to hold ADCOM? And what is the rationale for you to be so confident? And you have shown us a very excellent data, and also the points raised by CMS are important as well. And you have already said that you were able to answer those questions. And ADCOM, I believe that there shouldn't be any problem in holding this. But from an outsider's view, I think that it is quite uncertain or there are some points, which are not clear to us as outsider. Could you please explain?

Haruo Naito

Before me making comments about ADCOM, but I'd like to invite Ivan Cheung to introduce general view about ADCOM, and then I'd like to follow.

Unknown Attendee

#23

Okay, then I would like to ask Ivan Cheung to respond first.

Ivan Cheung

executive
#24

Yes. Thank you very much for the question. As you heard from CEO Naito, as you all know very well, since our CLARITY AD data presentation at CTAD last year and a simultaneous publication in New England Journal of Medicine, Eisai continues to uphold our principle to gain public trust in LEQEMBI through our clinical data transparency. So we very much welcome the FDA Advisory Committee meeting to be another productive occasion to share the highly statistically significant and clinically meaningful efficacy data as well as the consistent safety data from Clarity AD. Specifically to your question about the rationale behind the advisory committee for this application, as you know well, and this is really the first time in this class and actually any potential disease-modifying therapy for Alzheimer's disease. This is the first medicine going through that full traditional approval process. So I think to gain public trust, and given the fact that the CLARITY AD data is so robust, we believe this is a win-win situation to have an advisory committee meeting for many stakeholders for the public, for the FDA, for Eisai, for everyone involved. So I think this is, in our belief, a good move to go down this path.

Haruo Naito

executive
#25

I, myself, agree with Ivan in principle. So what kind of issues to be reviewed? Well, I cannot think of any specific issues. So the submission for full approval has been accepted by FDA. And I believe that they have thoroughly reviewed that, and they have granted a priority review status. So if there are any specific issues in the review and then are they going to ask the opinions from the ADCOM members about those issues? We do not know. And the schedule or date of the ADCOM is not specified yet. So if ADCOM is going to be held, we would like to take it rather positively with higher transparency, and we can be more convincing to the general public. We believe that, that will provide us such opportunity.

Seiji Wakao

analyst
#26

Understood clearly. My second question is about donanemab. Regarding the peak sales you mentioned, you said that you are going to be taking the largest share without data from donanemab being available. So you are saying that you will be able to get the top share. Because of the data available, I think that you have become confident enough, but based upon the data from donanemab, you do not think that donanemab will become a threat to you. So why do you think your product will take the largest share? And what kind of data are you expecting from donanemab? As far as you can, please mention them.

Unknown Executive

executive
#27

Our view is amyloid beta reduction based on the data from CLARITY AD study at 18 months turning into negative side. But after that, through the OLE study, A-beta deposition data was shown, there are some patients with a completely suppressed -- and there are some other patients who have shown the slight increase in trend in the amyloid. So the biweekly turning to monthly dosing with less frequent dosing and then turning into the maintenance period, and therefore, patients will continue to treat, we would like to establish such regimen or schedule of treatment. I believe that when we consider patient journey and welfare of patients, I think that this is the appropriate dosing regimen taking into -- such aspects into account. And of course, in maintenance period, those will be halved, therefore, the price will be halved as well, and the burden will be reduced. With such dosing, we are confident we have a Core and a gap and also OLE. And during the gap period in between the 2 study periods, we have understood what happened to the patients. So based upon that, we believe that the treatment needs to be continued. So I wonder if I am answering your question. This is what I can say now. The data itself from donanemab, I don't think I am in a position to mention any specific comments, so I'd like to refrain from making any comments. Thank you very much.

I'm Muraoka from Morgan Stanley. In January, you've commented on this. But what is the timing of turning profitable? There was a discussion of 150 or so sales reps. In the latter half of the second year to the third year or latter part of 2024 was the answer last time. JPY 200 billion of sales by 2024 and according to this, it might seem that it is possible to turn profitable in the second year in the latter part of 2024. How should we understand this? Can you share with us your thinking including scenario?

Unknown Executive

Internally, we are conducting a very detailed review, and we would like to achieve what, Mr. Muraoka, you exactly said.

Unknown Executive

#32

There has been rejuvenation by about 30 to 40 years of age when there was a change of guard. And now I'm 75. So it would mean that people in the 30 to 40s, but this is quite delicate, and I find it difficult to answer. Thank you. I will read between the lines.

So I'd like to take next question. The person in the second row from the front, please have the floor.

Akinori Ueda

analyst
#34

My name is Ueda. I'm from Goldman Sachs Securities. I would like to ask only one question because of the interest of time. On Page 15, your concept behind the pricing, so looking at this formula and going forward, the long-term data will become available and after accumulation of the evidence. And then is it possible for you to consider raising the price slightly? And in the Q&A session and SC formulation, you are considering different pricing. I think you commented that. So could you please explain what is going to be your view on the pricing?

Unknown Executive

executive
#35

Yes, as you said, from time to time, we needed to continue evaluation. I think that is important. Of course, the QALY may change. And the cost offset portion may change. Therefore, we needed to continue updating this. So by doing so, we will be able to respond to the pricing reflexively. So taking this opportunity because you asked this -- about this. So I'd like to say, in the United States, a free-of-charge provision, patient assistance program called PAP, it's being used in the United States. And going forward, when we roll out these products in Asia, PAP is going to play a key role. PAP does not generate any revenue for us. But yearly value terms, the PAP portion can be reflected on the yearly value. So impact weighted accounting is now being the buzzword. And for both, we would like to continue to report on both aspects. Regarding the SC, subcutaneous formulation. Yes, for SC formulation, this is going to be a separate filing with a different setting of the price. Yes. For SC, I believe SC will carry higher value.

Would there be any other questions from those of you in the room? If not, I -- we would now like to take questions from those who are participating online. We have a question. We understand that Barker-san from Jefferies would like to ask a question. Please unmute and please start.

Stephen Barker

analyst
#37

I'm Stephen Barker from Jefferies. My question is about CMS. Mr. Naito, CEO, according to what you've said, NCD, national coverage decision rule will be -- so CMS will be abiding by that NCD while considering the coverage of LEQEMBI and consider expansion of coverage. Specifically, how can coverage be expanded? Current NCD would mean that unless there are participation in clinical trials, coverage cannot be increased. So our large-scale clinical trial would lead to covering a larger number of people or without a clinical trial while abiding by the current NCD rule. Do you think that without going through a clinical trial, you can increase coverage?

Unknown Attendee

attendee
#38

The question will be addressed by Ivan Cheung.

Ivan Cheung

executive
#39

Thank you for the question. This is Ivan Cheung. If you look at the NCD document, it's very clear that each antibody will be judged on its own merit. So each antibody has to answer those 3 CED questions, which we believe the LEQEMBI data including both the CLARITY AD data and the Phase II plus Phase II long-term extension data fully answered those 3 questions. What does that mean? That's your question. If you look at the NCD document, which you see on this slide, we believe LEQEMBI can be qualified for a so-called high level of evidence in the NCD document. In that scenario, it's likely that the CMS could lift the CED requirement for LEQEMBI, meaning there is no access restriction. So that's one scenario. The other scenario could be that these data from LEQEMBI almost fully answered all the questions, and as a result, a very light CED may remain in place. That's also a possibility. That's not a clinical trial as you mentioned. In the NCD document, the CMS used the phrase registry, which can mean many things in terms of different ways of collecting any type of information in the real world. But again, as of this moment, our interactions with the CMS and our data sharing with the CMS, Eisai's position is that we fully answered all 3 CED questions qualified for high level of evidence, and we believe the CED for LEQEMBI should be lifted for the benefit for American seniors. Thank you.

Unknown Analyst

#41

Sanford, my name is [ Sugi ]. On Page 23, the patients to be treated with AD-DMT. Could you please explain this hypothesis? I have a question about this. When we have a discussion or interview with physicians in the United States, beta amyloid diagnosis as well as the [ beta ] after the amyloid diagnosis and whether or not patients will seek the treatment, actually, patients will not feel like going to the treatment stage. And there are many such patients, and particularly those senior patients going to seek the consultation at the hospital, that itself is difficult and also it requires infusion. And the efficacy of LEQEMBI, of course, can slow the progress of the disease. It is meaningful medically -- medically meaningful. However, this is not a cure from the perspective of patients, and it does not mean improvement. So when it comes to the actual confirmation of the beta amyloid and then patients may seek to proceed to the medical consultation treatment, and what is the comment? And I believe based upon the hypothesis that you have presented out of the patients who have the amyloid positive status, and then how are they going to transfer to the actual receipt of the treatment? And the current status, do you think that this situation can be changed? Or are there any plans of your company's activities [indiscernible]?

My name is Toyosaki. I am the global lead for LEQEMBI. Let me respond. As you pointed out, in the U.S. as well, after positivity of amyloid beta is confirmed, well, not everyone with positivity will seek the treatment with LEQEMBI. We believe that a certain percentage, which I do not know, have at hand. However, I would say that not every patient with positivity in amyloid will seek the treatment with LEQEMBI. Having said that, the clinical meaningfulness of this LEQEMBI is to the effect that the decline of the cognitive function for patients and their families and what benefits or impact will be brought about by this LEQEMBI, we needed to explain fully to them or asking the physicians to explain that fully to patients and their families. And then that will impact the acceptance of this drug. We like to enhance the acceptance by doing so.

Unknown Executive

#47

Let me supplement his explanation. As you asked in question, after confirming the positivity of amyloid beta, then becoming the eligible patients to be treated with AD-DMT, in between the 2 processes, there is another step. As you pointed out, you needed to consult and discuss with the attending physicians to determine whether would like to -- whether they would like to be treated with this drug or not. So that is taken into account and the number of patients treated with LEQEMBI was calculated.
