TOKYO and CAMBRIDGE, Mass., January 7, 2023 – Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) and Biogen Inc. (Nasdaq: BIIB, Corporate headquarters: Cambridge, Massachusetts, CEO: Christopher A. Viehbacher “Biogen”) announced Eisai has submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) supporting the conversion of the Accelerated Approval of LEQEMBI™ (lecanemab-irmb) 100 mg/mL injection for intravenous use to a traditional approval. This sBLA is subject to validation of whether the FDA accepts the application for review. LEQEMBI is a humanized immunoglobulin gamma 1 (IgG1) monoclonal antibody directed against aggregated soluble (“protofibrils”)* and insoluble forms of amyloid beta (Aβ), approved under Accelerated Approval Pathway by the FDA on January 6, 2023, for the treatment of Alzheimer’s Disease (AD). Treatment with LEQEMBI should only be initiated in patients with the mild cognitive impairment or mild dementia stage of disease and confirmed presence of Aβ pathology.
Accelerated Approval of LEQEMBI was based on Phase 2 data that demonstrated LEQEMBI reduced the accumulation of Aβ plaque in the brain, a defining feature of AD. Continued approval for this indication is contingent upon verification of LEQEMBI’s clinical benefit in a confirmatory trial. The sBLA for LEQEMBI is based on the data from the Phase 3 confirmatory Clarity AD clinical trial. In Clarity AD, LEQEMBI met the primary endpoint and all key secondary endpoints with highly statistically significant results, and the profile of Amyloid-Related Imaging Abnormalities (ARIA) incidence was within expectations. In November 2022, the results of the Clarity AD study were presented at the 2022 Clinical Trials on Alzheimer’s Disease (CTAD) conference, and simultaneously published in the New England Journal of Medicine, peer-reviewed medical journals.
“We deeply appreciate the cooperation of people living with Alzheimer’s disease and healthcare professionals who participated in LEQEMBI’s Phase 3 Clarity AD clinical study, which enabled us to submit this sBLA. Alzheimer’s disease causes significant impairment and burden to both the people living with this disease and their families, as well as having a profound impact on society,” said Haruo Naito, Chief Executive Officer at Eisai. “The fact that Eisai was able to file LEQEMBI’s supplemental Biologics License Application for traditional FDA approval on the same day we received accelerated approval demonstrates our commitment to the Alzheimer’s disease community and is a major step forward in ensuring access for all those in the U.S living with this disease in need of this medicine. We will continue to actively cooperate with the FDA’s review.”
Eisai has initiated submission of data for BLA to the National Medical Products Administration (NMPA) of China in December 2022. Eisai plans to file for marketing authorization applications of lecanemab in Japan and EU by the end of Eisai’s FY2022, which ends March 31, 2023.
“Today’s filing is an important milestone for people living with Alzheimer’s disease, demonstrating the resilience of the scientific and medical communities in their fight against this terrible disease despite the many setbacks and the challenges they’ve faced,” said Christopher A. Viehbacher, President and Chief Executive Officer of Biogen. “We commend Eisai for their leadership on the development of lecanemab and for the speed in which they were able to complete this filing, which is based on important new data from the pivotal late-stage Clarity AD study.”
Eisai serves as the lead of LEQEMBI development and regulatory submissions globally with both Eisai and Biogen co-commercializing and co-promoting the product and Eisai having final decision-making authority.

INDICATION, DOSAGE AND ADMINISTRATION, AND IMPORTANT SAFETY INFORMATION IN THE U.S
INDICATION
LEQEMBI is indicated for the treatment of Alzheimer’s disease. Treatment with LEQEMBI should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical trials. There are no safety or effectiveness data on initiating treatment at earlier or later stages of the disease than were studied. This indication is approved under accelerated approval based on reduction in amyloid beta plaques observed in patients treated with LEQEMBI. Continued approval for this indication may be contingent upon verification of clinical benefit in a confirmatory trial.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Amyloid Related Imaging Abnormalities
- LEQEMBI can cause amyloid related imaging abnormalities-edema (ARIA-E) and -hemosiderin deposition (ARIA-H). ARIA-E can be observed on MRI as brain edema or sulcal effusions, and ARIA-H as microhemorrhage and superficial siderosis. ARIA is usually asymptomatic, although serious and life threatening events, including seizure and status epilepticus, rarely can occur. Reported symptoms associated with ARIA may include headache, confusion, visual changes, dizziness, nausea, and gait difficulty. Focal neurologic deficits may also occur. Symptoms associated with ARIA usually resolve over time.
ARIA Monitoring and Dose Management Guidelines
- Obtain recent (within one year) brain magnetic resonance imaging (MRI) prior to initiating treatment with LEQEMBI. Obtain an MRI prior to the 5th, 7th, and 14th infusions.
- Recommendations for dosing in patients with ARIA-E and ARIA-H depend on clinical symptoms and radiographic severity. Depending on ARIA severity, use clinical judgment in considering whether to continue dosing, temporarily discontinue treatment, or permanently discontinue LEQEMBI.
- Enhanced clinical vigilance for ARIA is recommended during the first 14 weeks of treatment with LEQEMBI. If a patient experiences symptoms suggestive of ARIA, clinical evaluation should be performed, including MRI if indicated. If ARIA is observed on MRI, careful clinical evaluation should be performed prior to continuing treatment.
- There is no experience in patients who continued dosing through symptomatic ARIA-E or through asymptomatic, but radiographically severe, ARIA-E. There is limited experience in patients who continued dosing through asymptomatic but radiographically mild to moderate ARIA-E. There are limited data in dosing patients who experienced recurrent ARIA-E.
Incidence of ARIA
- In Study 1 (Study 201), symptomatic ARIA occurred in 3% (5/161) of LEQEMBI-treated patients. Clinical symptoms associated with ARIA resolved in 80% of patients during the period of observation.
- Including asymptomatic cases, ARIA was observed in LEQEMBI: 12% (20/161); placebo: 5% (13/245). ARIA-E was observed in LEQEMBI: 10% (16/161); placebo: 1% (2/245). ARIA-H was observed in LEQEMBI: 6% (10/161); placebo: 5% (12/245). There was no increase in isolated ARIA-H for LEQEMBI compared to placebo.
- Intracerebral hemorrhage >1 cm in diameter was reported after one treatment in LEQEMBI: 1 patient; placebo: zero patients. Events of intracerebral hemorrhage, including fatal events, in patients taking LEQEMBI have also been reported in other studies.
Apolipoprotein E ε4 (ApoE ε4) Carrier Status and Risk of ARIA
- In Study 1, 6% (10/161) of patients in the LEQEMBI group were ApoE ε4 homozygotes, 24% (39/161) were heterozygotes, and 70% (112/161) were noncarriers.
- The incidence of ARIA was higher in ApoE ε4 homozygotes than in heterozygotes and noncarriers among patients treated with LEQEMBI. Of the 5 LEQEMBI-treated patients who had symptomatic ARIA, 4 were ApoE ε4 homozygotes, 2 of whom experienced severe symptoms. An increased incidence of symptomatic and overall ARIA in ApoE ε4 homozygotes compared to heterozygotes and noncarriers in LEQEMBI-treated patients has been reported in other studies.
- The recommendations on management of ARIA do not differ between ApoE ε4 carriers and noncarriers.
- Consider testing for ApoE ε4 status to inform the risk of developing ARIA when deciding to initiate treatment with LEQEMBI.
Radiographic Findings
- The majority of ARIA-E radiographic events occurred early in treatment (within the first 7 doses), although ARIA can occur at any time and patients can have more than 1 episode. The maximum radiographic severity of ARIA-E in patients treated with LEQEMBI was mild in 4% (7/161) of patients, moderate in 4% (7/161) of patients, and severe in 1% (2/161) of patients. Resolution on MRI occurred in 62% of ARIA-E patients by 12 weeks, 81% by 21 weeks, and 94% overall after detection. The maximum radiographic severity of ARIA-H microhemorrhage in patients treated with LEQEMBI was mild in 4% (7/161) of patients and severe in 1% (2/161) of patients; of the 10 patients with ARIA-H had mild superficial siderosis.
Concomitant Antithrombotic Medication and Other Risk Factors for Intracerebral Hemorrhage
- Patients were excluded from enrollment in Study 1 for baseline use of anticoagulant medications. Antiplatelet medications such as aspirin and clopidogrel were allowed. If anticoagulant medication was used because of intercurrent medical events that required treatment for ≤4 weeks, treatment with LEQEMBI was to be temporarily suspended.
- Most exposures to antithrombotic medications were to aspirin; few patients were exposed to other antiplatelet drugs or anticoagulants, limiting any meaningful conclusions about the risk of ARIA or intracerebral hemorrhage in patients taking other antiplatelet drugs or anticoagulants. Because intracerebral hemorrhages >1 cm in diameter have been observed in patients taking LEQEMBI, additional caution should be exercised when considering the administration of antithrombotics or a thrombolytic agent (e.g., tissue plasminogen activator) to a patient already being treated with LEQEMBI.
- Patients were excluded from enrollment in Study 1 for the following risk factors for intracerebral hemorrhage: prior cerebral hemorrhage >1 cm in greatest diameter, more than 4 microhemorrhages, superficial siderosis, evidence of vasogenic edema, evidence of cerebral contusion, aneurysm, vascular malformation, infective lesions, multiple lacunar infarcts or stroke involving a major vascular territory, and severe small vessel or white matter disease. Caution should be exercised when considering the use of LEQEMBI in patients with these risk factors.
Infusion-Related Reactions
- Infusion-related reactions were observed in LEQEMBI: 20% (32/161); placebo: 3% (8/245), and the majority of cases in LEQEMBI-treated patients (88%, 28/32) occurred with the first infusion. All infusion related reactions were mild (56%) or moderate (44%) in severity. Infusion-related reactions resulted in discontinuations in 2% (4/161) of patients treated with LEQEMBI. Symptoms of infusion-related reactions included fever and flu-like symptoms (chills, generalized aches, feeling shaky, and joint pain), nausea, vomiting, hypotension, hypertension, and oxygen desaturation.
- After the first infusion, 38% of LEQEMBI-treated patients had transient decreased lymphocyte counts to <0.9 x109/L compared to 2% on placebo, and 22% of LEQEMBI-treated patients had transient increased neutrophil counts to >7.9 x109/L compared to 1% on placebo.
- In the event of an infusion-related reaction, the infusion rate may be reduced, or the infusion may be discontinued, and appropriate therapy initiated as clinically indicated. Prophylactic treatment with antihistamines, acetaminophen, nonsteroidal anti-inflammatory drugs, or corticosteroids prior to future infusions may be considered.
ADVERSE REACTIONS
- In Study 1, 15% of LEQEMBI-treated patients, compared to 6% of placebo-treated patients, stopped study treatment because of an adverse reaction. The most common adverse reaction leading to discontinuation of LEQEMBI was infusion-related reactions that led to discontinuation in 2% (4/161) of patients treated with LEQEMBI compared to 1% (2/245) of patients on placebo.
- The most common adverse reactions reported in ≥5% of patients treated with LEQEMBI (N=161) and ≥2% higher than placebo (N=245) in Study 1 were infusion-related reactions (LEQEMBI: 20%; placebo: 3%), headache (LEQEMBI: 14%; placebo: 10%), ARIA-E (LEQEMBI: 10%; placebo: 1%), cough (LEQEMBI: 9%; placebo: 5%), and diarrhea (LEQEMBI: 8%; placebo: 5%).

Notes to Editors
1. About LEQEMBITM (lecanemab-irmb)
LEQEMBITM (lecanemab-irmb) is a humanized immunoglobulin gamma 1 (IgG1) monoclonal antibody that is directed against aggregated soluble (“protofibrils”) and insoluble forms of amyloid-beta (Aβ). LEQEMBI is indicated for the treatment of Alzheimer’s disease (AD) in the U.S. Treatment with LEQEMBI should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical trials. There are no safety or effectiveness data on initiating treatment at earlier or later stages of the disease than were studied. This indication is approved under accelerated approval based on reduction in Aβ plaques observed in patients treated with LEQEMBI. Continued approval for this indication may be contingent upon verification of clinical benefit in a confirmatory trial.
LEQEMBI is the result of a strategic research alliance between Eisai and BioArctic. Eisai has been initiated submission of data for the BLA to the National Medical Products Administration (NMPA) of China in December 2022. Eisai plans to file for marketing authorization applications of lecanemab in Japan and EU by the end of Eisai’s FY2022.
Since July 2020, Eisai’s Phase 3 clinical study (AHEAD 3-45) for individuals with preclinical AD, meaning they are clinically normal and have intermediate or elevated levels of amyloid in their brains, is ongoing. AHEAD 3-45 is conducted as a public-private partnership between the Alzheimer’s Clinical Trial Consortium that provides the infrastructure for academic clinical trials in AD and related dementias in the U.S., funded by the National Institute on Aging, part of the National Institutes of Health, Eisai and Biogen.
The Tau NexGen clinical study for Dominantly Inherited AD (DIAD), that is conducted by Dominantly Inherited Alzheimer Network Trials Unit (DIAN-TU), led by Washington University School of Medicine in St. Louis, has been ongoing since January 2022. Eisai has completed a LEQEMBI subcutaneous bioavailability study, and subcutaneous dosing is currently being evaluated in the Clarity AD (Study 301) OLE.
2. About Amyloid-Related Imaging Abnormalities (ARIA)
ARIA is an important adverse event of amyloid-lowering therapies that is critical to monitor and manage during treatment. ARIA is most commonly seen as temporary swelling/effusion (ARIA-E) in areas of the brain that usually resolves over time. Some people may also have small spots of bleeding in or on the surface of the brain (ARIA-H) with the swelling. Although most people with ARIA-E do not have symptoms, some people may have symptoms such as headache, confusion, dizziness, vision changes and nausea.
3. About the Collaboration between Eisai and Biogen for AD
Eisai and Biogen have been collaborating on the joint development and commercialization of AD treatments since 2014.

Hope for Patients with Early Alzheimer’s Disease
LEQEMBI™ (lecanemab-rimb) has the potential to make a difference for people living with early Alzheimer’s disease (AD), their loved ones and healthcare professionals, and was recently approved by the U.S. Food and Drug Administration (FDA) for the treatment of AD. Eisai has worked with the FDA and the FDA has approved the LEQEMBI U.S. Prescribing Information (USPI) and Medication Guide, which provides a summary of the essential scientific information needed for the appropriate use of the product. This information will allow healthcare providers, patients and their families to make an informed decision regarding LEQEMBI therapy and will provide guidance to healthcare providers on how to monitor patients for potential side effects, such as amyloid-related imaging abnormalities (ARIA). As with all therapies, patients and their families will need to discuss the benefits and risks in relation to their condition and medical history with their healthcare provider, prior to initiating treatment.
Patient Safety is Eisai’s Priority
First and foremost, the well-being and privacy of the patients enrolled in our clinical studies or prescribed our medications are always Eisai’s top priority. Eisai has an experienced team responsible for collecting and analyzing adverse events (including any fatalities) possibly related to its investigational drugs or commercially available medicines. These adverse events and other safety information from any source undergo continuous review to fully inform our knowledge of the safety profile of Eisai’s products. This information is provided to the FDA and other regulatory authorities consistent with their requirements and guidelines. Eisai promptly communicates important safety information to regulatory agencies, clinical trial sites, clinical trial investigators and patients through the established notification methods, including clinical trial site communications, Independent Review Board (IRB) communications and patient Informed Consent Forms (ICF) as required by the various health authorities. Eisai works closely with regulatory agencies to update approved product information with new safety information.
Important Considerations in the Study of Alzheimer’s Disease
Part of Eisai’s commitment to patient safety is studying the frequency, pattern, causes and risk factors of diseases and health-related events in different populations. According to the World Health Organization (WHO), dementia is the seventh leading cause of death among all diseases1 and the Centers for Disease Control and Prevention (CDC) reports that AD is the leading cause of dementia and the fifth leading cause of death for those 65 years and older.2 According to the Alzheimer’s Association, the average survival after diagnosis is typically three to eleven years (median survival time: eight years).3 The patients who participate in trials for AD treatments have a relatively high rate of mortality due to the physical effects resulting from the natural progression of AD and the variety of medical conditions that develop as people continue to age. For example, comprehensive reviews of the scientific literature have found that patients with AD have a significantly higher incidence of hemorrhagic strokes (strokes associated with bleeding in the brain).4 When evaluating suspected serious adverse reactions, including death, of any clinical trial participants or patients prescribed medications outside clinical trials, one must consider factors like age, clinical history, concomitant medications, temporal correlation, biologic plausibility, and effects of dechallenge/rechallenge of the suspected drug.
Understanding Amyloid-Related Imaging Abnormalities (ARIA)
Monoclonal antibodies directed against aggregated forms of beta amyloid, including LEQEMBI, can cause ARIA characterized as ARIA with edema (ARIA-E), which can be observed on magnetic resonance imaging (MRI) as brain edema or sulcal effusions, and ARIA with hemosiderin deposition (ARIA-H), which includes microhemorrhage and superficial siderosis.5 ARIA and infusion reactions are important side effects that can be seen with LEQEMBI treatment.
ARIA-H can occur spontaneously in patients with AD. ARIA-H associated with monoclonal antibodies directed against aggregated forms of beta amyloid generally occurs in association with an occurrence of ARIA-E. ARIA-H of any cause and ARIA-E can occur together. ARIA is usually asymptomatic, although serious and life-threatening events, including seizure and status epilepticus, rarely can occur. When present, reported symptoms associated with ARIA may include headache, confusion, visual changes, dizziness, nausea and gait difficulty, and focal neurologic deficits may also occur. These symptoms usually resolve over time. Intracerebral hemorrhage greater than 1 cm in diameter has been reported. Events of intracerebral hemorrhage, including fatal events, in patients taking LEQEMBI have also been reported.5
The USPI provides physicians with important clinical information on, among others, the incidence and classification criteria for ARIA, how to monitor, and recommendations for dosing interruptions in patients with ARIA. Prescribing physicians are also instructed to obtain a recent (within one year) brain magnetic resonance imaging (MRI) prior to initiating treatment with LEQEMBI as well as an MRI prior to the 5th, 7th and 14th infusions. Enhanced clinical vigilance for ARIA is recommended during the first 14 weeks of treatment with LEQEMBI. Risk of ARIA, including symptomatic ARIA, was increased in apolipoprotein E ε4 homozygotes compared to heterozygotes and noncarriers. If a patient experiences symptoms suggestive of ARIA, clinical evaluation should be performed, including MRI scanning if indicated. Please review the complete USPI for important safety information on ARIA and infusion-related reactions.5
On November 29, 2022, the confirmatory Phase III CLARITY AD clinical trial results for LEQEMBI were published in The New England Journal of Medicine6 and presented at the 15th Annual Clinical Trials on Alzheimer’s Disease (CTAD) conference.7 The overall mortality rates observed in both the LEQEMBI and placebo groups in the CLARITY AD clinical trial were similar and below the age-adjusted mortality rates reported by the CDC for the U.S. population.8 The results of the confirmatory CLARITY AD study are anticipated to be submitted to the FDA very shortly for review for traditional approval.
Media Inquiries on Individual Cases
As we explained in our December 23, 2022, statement, Eisai takes seriously our responsibility to protect the safety and privacy of patients who contribute to medical science by participating in our studies. Outside of scientific papers in peer-reviewed journals or scientific conferences, it would be inappropriate to provide additional information about specific patients or comment on information that was provided by other sources.
On January 4, The New England Journal of Medicine (NEJM) published two peer-reviewed letters about a tragic individual case9,10. The NEJM letters provide medical perspectives to this case previously reported by the media. Eisai will continue to examine and publish data in peer-reviewed medical journals and present findings to the scientific community at medical congresses.
We are incredibly grateful to patients, families and the healthcare provider community for their participation in clinical research to help combat AD and all other devastating diseases.

MAXIMIZING VALUE FOR ALL STAKEHOLDERS WHILE GIVING BACK VALUE TO SOCIETY
For Print(PDF)(364KB)
Based on hhc (human health care) concept, our corporate philosophy, Eisai is committed to improve patients health outcomes and quality of life, simplify care delivery, increase health system efficiency and spur future investments in Alzheimer’s disease (AD). We consider a holistic approach in assessing value and making decisions that may affect patient access, so that our LEQEMBI pricing approach can maximize value for all stakeholders (patients, families, caregivers, healthcare providers, payers, employees and shareholders). This approach includes clinical outcome assessments of our medicines and the benefits we deliver to patients, their families and caregivers as the “clinical value,” as well as the projected “social value” that help improve patients’ and caregivers’ quality of life and productivity. Moreover, we assess the simulated impact of our medicines on reducing demand for health services and global burden of disease as potential “economic value” while enhancing further innovations in AD.
Social Impact of AD in the U.S.
According to the Alzheimer’s Association’s “2022 Alzheimer’s Disease Facts and Figures”1, an estimated 6.5 million Americans aged 65 and older are living with dementia due to AD (i.e., mild, moderate and severe dementia stages of AD). AD was officially listed as the sixth-leading cause of death in the U.S. in 2019 and the seventh-leading cause of death in 2020 and 2021. It is a chronic, progressive, disabling and fatal disease. According to another report from the Alzheimer’s Association, “Changing the Trajectory of Alzheimer’s Disease: How a Treatment by 2025 Saves Lives and Dollars”2, the total costs of care in the U.S. from all payers (i.e., Medicare, Medicaid, out-of-pocket and other payers), would increase from $267 Billion in 2020 to $451 Billion in 2030 if no treatment exists to delay the disease.
A recent 2022 study, “Projecting the Long-term Societal Values of Disease-Modifying Treatment for Alzheimer’s Disease in the United States”3, quoted as many as 10 to 14 million Americans living with MCI (Mild Cognitive Impairment) of any etiology, the very mild symptomatic stage before onset of dementia stages, in which 55% have AD as the underlying pathology. In this study, the lifetime value of a disease-modifying treatment in Early AD (MCI due to AD and mild dementia stage of AD) from a U.S. societal perspective assuming a treatment effect of 30% relative decline in progression rates from MCI to mild dementia and from mild to moderate dementia was estimated at $134,418 per person.
Value of LEQEMBI Adoption to U.S. Society
LEQEMBI is indicated for the treatment of AD, and treatment with LEQEMBI should be initiated in patients with MCI or mild dementia stage of AD after confirmation of amyloid beta pathology (Early AD). In the U.S., we estimate that the diagnosed eligible Early AD population will reach approximately 100,000 individuals by year 3 representing a measured initial attainment in the real world and will increase gradually over the mid-to-long term given the time required to advance new screening and diagnostic technologies such as blood-based biomarkers to confirm amyloid beta pathology.
Published findings in a peer-reviewed journal4 from the confirmatory Phase 3 Clarity AD study in patients with Early AD demonstrate that LEQEMBI treatment resulted in less decline on measures of cognition and function than placebo at 18 months (27% slowing over 18 months measured by CDR-SB*) and was associated with adverse events that were within expectation. Clarity AD results were consistent with that from the Phase 2 trial (Study 201)5 that was the basis for the FDA’s accelerated approval and will be submitted to the FDA very shortly for review for traditional approval.
LEQEMBI’s clinical data show that it could help patients maintain cognition, preserve activities of daily living and maintain functional ability for longer, and therefore, LEQEMBI’s clinical efficacy could potentially translate into impactful outcomes for these patients and their families. A simulation study using an established, validated disease model called Alzheimer’s disease Archimedes condition event (AD ACE),6,7,8 which is an individual patient-level model with a focus on predicting the trajectory of cognitive decline and simulating the effects of early interventions in AD, helped assess the potential lifetime value and economic impact of LEQEMBI in patients with Early AD based on clinical trial populations and findings. The results9,10 of this simulation study based on Study 201 of LEQEMBI were published in a peer-reviewed journal, and the model has been recently updated with data from the Clarity AD trial showing consistent outputs.
Per Patient Societal Value of LEQEMBI at $37,600 per Year in the U.S. by AD ACE Model
In the updated AD ACE simulation study using Clarity AD data, LEQEMBI treatment was projected to delay disease progression, resulting in an increase in patient’s expected time in Early AD while reducing the time in more advanced severe states. Slowing of clinical decline in patients treated with LEQEMBI is estimated to delay disease progression by nearly 3 years on average (delay progression mainly from MCI to mild AD and from mild to moderate AD) compared to standard-of-care (SOC). LEQEMBI’s impact on the disease trajectory is then modeled into an annual per-patient value to the U.S. society based on four components according to the following equation: a) quality-adjusted life-years (QALY) gains compared to SOC; b) willingness-to-pay (WTP) threshold; c) cost offsets compared to SOC; and d) time on treatment, all in present value term. Note that the costs, benefits and time on treatment need to be adjusted for the values between present time and future times using discounting in a health economic evaluation.

With regard to a) QALY gains, since health is a function of length of life and quality of life, this measure combines both attributes into one single index, with one QALY gain representing one additional year of a person’s life at perfect health. LEQEMBI treatment was predicted to offer an additional 0.64 QALYs compared to SOC for an Early AD patient over lifetime by improving outcomes for both the patient and caregiver. With regard to b) WTP threshold per QALY gained, conventionally, the WTP threshold is based on 1 to 3 times country’s per capita gross domestic product (GDP). In the U.S., as a result, a WTP threshold of $50,000 to $150,000 is referenced as the cost-effectiveness threshold11, but a higher WTP threshold is often considered to account for the gravity of conditions with greater burden, and interventions that exhibit wider societal benefits, such as AD with substantial impacts on caregivers. A modified societal perspective at $200,000 WTP threshold per QALY gained is used in the U.S. when societal cost of the disease is large such as AD. With regard to c) cost offsets, avoidance of both direct medical/non-medical costs for AD management, as well as indirect costs of caregivers including family members totaling $7,415 over the lifetime for each Early AD patient, was predicted with LEQEMBI treatment compared to SOC. Direct costs contain cost of medications, medical visits, hospitalizations, living accommodations and community services for the patients. Indirect costs of caregivers, including family members, consider the monetary value for hours spent on caregiving activities. With regard to: d) time on treatment, LEQEMBI was modeled to be stopped upon transition to moderate AD dementia or worse. The average treatment duration in this Early AD population was estimated to be approximately 3.6 years with consideration of discounting to present value.
Taking all four components together in present value term, for a) 0.64 QALYs gained b) at WTP threshold of $200,000 per QALY gained plus c) cost offsets of $7,415 over d) 3.6 years on treatment, the yearly per-patient value of LEQEMBI from a societal perspective was quantified at approximately $37,600.

This yearly estimate of $37,600 equals to approximately $135,000 (0.64 × $200,000 + $7,415) in lifetime value per patient to the U.S. society. Over 10 years cumulatively, the gradual adoption of LEQEMBI treatment among Early AD patients could potentially generate positive social impact of several tens of billion dollars to the U.S. society, in the form of “clinical value” that help patients delay their disease progression, projected “social value” that help improve patients’ and caregivers’ quality of life and productivity, and simulated “economic value” that help reduce demand for health services.
LEQEMBI U.S. Launch Pricing at $26,500 per Year
While we estimate the per-patient-per-year value of LEQEMBI treatment to the U.S. society to be $37,600, Eisai decided to price LEQEMBI below quantified societal value at the wholesale acquisition cost (WAC) of $26,500 per year (estimated annual price based on 10mg/kg IV biweekly for average U.S. patient weight of 75kg based on Study 201 and Clarity AD) aiming to promote broader patient access, reduce overall financial burden, and support health system sustainability. As such, the WAC for the 200mg vial is $254.81 and the WAC for the 500mg vial is $637.02. Actual annualized pricing may vary by patient. In addition, Eisai continues to pursue a less frequent maintenance dosing regimen for LEQEMBI, such as monthly instead of current biweekly regimen, upon significant amyloid beta clearance to prevent re-accumulation of amyloid beta biomarkers while maintaining clinical efficacy. This could further lower the yearly cost of LEQEMBI during the maintenance dosing phase, for example, from $26,500 to potentially about half of this figure given less amount of drugs.
Patient Affordability
Eisai believes patient affordability must be a key consideration to promote patient access and intended use and benefits of LEQEMBI. Among the eligible Early AD patient population in the U.S., once the patient’s insurer covers LEQEMBI, we estimate that approximately 91% of individuals will be covered by Medicare with Medigap (supplemental insurance), Medicare Advantage (Medicare-approved plans from private companies with potential supplemental coverage), Medicaid, and Commercial (private insurance12). For these patients, their out-of-pocket costs for LEQEMBI treatment could range from $0 to a few dollars per day. Remaining 9% of the individuals will fall into the category of Medicare without supplemental insurance, and hence will be responsible for 20% of the LEQEMBI cost as co-insurance under Medicare Part B. For these patients, their estimated out-of-pocket costs for LEQEMBI at the price of $26,500 per year will translate into about $14.50 per day13. Across the entire eligible Early AD patient population, we estimate the weighted average out-of-pocket costs for LEQEMBI to be about $2 per day12.
Commitment to Patient Access
Eisai is committed to ensuring that certain financially disadvantaged patients have access to LEQEMBI. Firstly, Eisai is establishing a Patient Assistance Program, which will provide LEQEMBI at no cost, for eligible uninsured and underinsured patients, including Medicare beneficiaries, who meet financial need and other program criteria. Secondly, Eisai will offer patient support for improving access through LEQEMBI Patient Navigators, who will provide information about accessing LEQEMBI, help patients and their families understand their insurance coverage and options, and identify financial support programs for eligible patients.
Health System Sustainability
We believe our pricing approach for LEQEMBI would also help improve health system sustainability, which is projected based on appropriate use of LEQEMBI in eligible patients with Early AD to improve patient’s health outcomes and quality of life and reduce demand for health services and global burden of disease through changing disease trajectory. Furthermore, we believe our pricing approach for LEQEMBI, coupled with the size of the targeted patient population, will be sustainable under historical growth and spending assumptions for Medicare Part B.
Giving Back More Than Half of LEQEMBI Value to U.S. Society
The price of LEQEMBI at a yearly cost of $26,500 is $11,100 below the projected societal value of $37,600, and a less frequent maintenance dosing regimen will further lower the yearly cost well below the projected societal value. Taking these savings as well as discounts and rebates within the U.S. healthcare system into consideration, over 10 years cumulatively, the gradual adoption of LEQEMBI treatment at this pricing approach could give back about 60% of the potential positive social impact of several tens of billion dollars to the U.S. society14. These resources could help realize new innovations that enhance the health and quality of life of individuals at risk of developing or living with AD as well as their families and caregivers. On the other hand, about 40% of the potential positive social impact of several tens of billion dollars will be accrued by employees and shareholders in the form of product sales, from which we are committed to re-invest in future research and development to create new AD therapies and new innovations such as establishing ecosystems toward inclusive AD communities14. We deeply believe that our pricing approach to maximize value for all stakeholders will help Eisai achieve social good in the form of relieving anxiety over health and reducing health disparity according to our corporate philosophy.

Notes to Editors
INDICATION, DOSAGE AND ADMINISTRATION, AND IMPORTANT SAFETY INFORMATION IN THE U.S.
INDICATION
LEQEMBI is indicated for the treatment of Alzheimer’s disease. Treatment with LEQEMBI should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical trials. There are no safety or effectiveness data on initiating treatment at earlier or later stages of the disease than were studied. This indication is approved under accelerated approval based on reduction in amyloid beta plaques observed in patients treated with LEQEMBI. Continued approval for this indication may be contingent upon verification of clinical benefit in a confirmatory trial.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Amyloid Related Imaging Abnormalities
- LEQEMBI can cause amyloid related imaging abnormalities-edema (ARIA-E) and -hemosiderin deposition (ARIA-H). ARIA-E can be observed on MRI as brain edema or sulcal effusions, and ARIA-H as microhemorrhage and superficial siderosis. ARIA is usually asymptomatic, although serious and life-threatening events, including seizure and status epilepticus, rarely can occur. Reported symptoms associated with ARIA may include headache, confusion, visual changes, dizziness, nausea, and gait difficulty. Focal neurologic deficits may also occur. Symptoms associated with ARIA usually resolve over time.
ARIA Monitoring and Dose Management Guidelines
- Obtain recent (within one year) brain magnetic resonance imaging (MRI) prior to initiating treatment with LEQEMBI. Obtain an MRI prior to the 5th, 7th, and 14th infusions.
- Recommendations for dosing in patients with ARIA-E and ARIA-H depend on clinical symptoms and radiographic severity. Depending on ARIA severity, use clinical judgment in considering whether to continue dosing, temporarily discontinue treatment, or permanently discontinue LEQEMBI.
- Enhanced clinical vigilance for ARIA is recommended during the first 14 weeks of treatment with LEQEMBI. If a patient experiences symptoms suggestive of ARIA, clinical evaluation should be performed, including MRI if indicated. If ARIA is observed on MRI, careful clinical evaluation should be performed prior to continuing treatment.
- There is no experience in patients who continued dosing through symptomatic ARIA-E or through asymptomatic, but radiographically severe, ARIA-E. There is limited experience in patients who continued dosing through asymptomatic but radiographically mild to moderate ARIA-E. There are limited data in dosing patients who experienced recurrent ARIA-E.
Incidence of ARIA
- In Study 1 (Study 201), symptomatic ARIA occurred in 3% (5/161) of LEQEMBI-treated patients. Clinical symptoms associated with ARIA resolved in 80% of patients during the period of observation.
- Including asymptomatic cases, ARIA was observed in LEQEMBI: 12% (20/161); placebo: 5% (13/245). ARIA-E was observed in LEQEMBI: 10% (16/161); placebo: 1% (2/245). ARIA-H was observed in LEQEMBI: 6% (10/161); placebo: 5% (12/245). There was no increase in isolated ARIA-H for LEQEMBI compared to placebo.
- Intracerebral hemorrhage >1 cm in diameter was reported after one treatment in LEQEMBI: 1 patient; placebo: zero patients. Events of intracerebral hemorrhage, including fatal events, in patients taking LEQEMBI have also been reported in other studies.
Apolipoprotein E ε4 (ApoE ε4) Carrier Status and Risk of ARIA
- In Study 1, 6% (10/161) of patients in the LEQEMBI group were ApoE ε4 homozygotes, 24% (39/161) were heterozygotes, and 70% (112/161) were noncarriers.
- The incidence of ARIA was higher in ApoE ε4 homozygotes than in heterozygotes and noncarriers among patients treated with LEQEMBI. Of the 5 LEQEMBI-treated patients who had symptomatic ARIA, 4 were ApoE ε4 homozygotes, 2 of whom experienced severe symptoms. An increased incidence of symptomatic and overall ARIA in ApoE ε4 homozygotes compared to heterozygotes and noncarriers in LEQEMBI-treated patients has been reported in other studies.
- The recommendations on management of ARIA do not differ between ApoE ε4 carriers and noncarriers.
- Consider testing for ApoE ε4 status to inform the risk of developing ARIA when deciding to initiate treatment with LEQEMBI.
Radiographic Findings
- The majority of ARIA-E radiographic events occurred early in treatment (within the first 7 doses), although ARIA can occur at any time and patients can have more than 1 episode. The maximum radiographic severity of ARIA-E in patients treated with LEQEMBI was mild in 4% (7/161) of patients, moderate in 4% (7/161) of patients, and severe in 1% (2/161) of patients. Resolution on MRI occurred in 62% of ARIA-E patients by 12 weeks, 81% by 21 weeks, and 94% overall after detection. The maximum radiographic severity of ARIA-H microhemorrhage in patients treated with LEQEMBI was mild in 4% (7/161) of patients and severe in 1% (2/161) of patients; 1 of the 10 patients with ARIA-H had mild superficial siderosis.
Concomitant Antithrombotic Medication and Other Risk Factors for Intracerebral Hemorrhage
- Patients were excluded from enrollment in Study 1 for baseline use of anticoagulant medications. Antiplatelet medications such as aspirin and clopidogrel were allowed. If anticoagulant medication was used because of intercurrent medical events that required treatment for ≤4 weeks, treatment with LEQEMBI was to be temporarily suspended.
- Most exposures to antithrombotic medications were to aspirin; few patients were exposed to other antiplatelet drugs or anticoagulants, limiting any meaningful conclusions about the risk of ARIA or intracerebral hemorrhage in patients taking other antiplatelet drugs or anticoagulants. Because intracerebral hemorrhages >1 cm in diameter have been observed in patients taking LEQEMBI, additional caution should be exercised when considering the administration of antithrombotics or a thrombolytic agent (e.g., tissue plasminogen activator) to a patient already being treated with LEQEMBI.
- Patients were excluded from enrollment in Study 1 for the following risk factors for intracerebral hemorrhage: prior cerebral hemorrhage >1 cm in greatest diameter, more than 4 microhemorrhages, superficial siderosis, evidence of vasogenic edema, evidence of cerebral contusion, aneurysm, vascular malformation, infective lesions, multiple lacunar infarcts or stroke involving a major vascular territory, and severe small vessel or white matter disease. Caution should be exercised when considering the use of LEQEMBI in patients with these risk factors.
Infusion-Related Reactions
- Infusion-related reactions were observed in LEQEMBI: 20% (32/161); placebo: 3% (8/245), and the majority of cases in LEQEMBI-treated patients (88%, 28/32) occurred with the first infusion. All infusion-related reactions were mild (56%) or moderate (44%) in severity. Infusion-related reactions resulted in discontinuations in 2% (4/161) of patients treated with LEQEMBI. Symptoms of infusion-related reactions included fever and flu-like symptoms (chills, generalized aches, feeling shaky, and joint pain), nausea, vomiting, hypotension, hypertension, and oxygen desaturation.
- After the first infusion, 38% of LEQEMBI-treated patients had transient decreased lymphocyte counts to <0.9 x109/L compared to 2% on placebo, and 22% of LEQEMBI-treated patients had transient increased neutrophil counts to >7.9 x109/L compared to 1% on placebo.
- In the event of an infusion-related reaction, the infusion rate may be reduced, or the infusion may be discontinued, and appropriate therapy initiated as clinically indicated. Prophylactic treatment with antihistamines, acetaminophen, nonsteroidal anti-inflammatory drugs, or corticosteroids prior to future infusions may be considered.
ADVERSE REACTIONS
- In Study 1, 15% of LEQEMBI-treated patients, compared to 6% of placebo-treated patients, stopped study treatment because of an adverse reaction. The most common adverse reaction leading to discontinuation of LEQEMBI was infusion-related reactions that led to discontinuation in 2% (4/161) of patients treated with LEQEMBI compared to 1% (2/245) of patients on placebo.
- The most common adverse reactions reported in ≥5% of patients treated with LEQEMBI (N=161) and ≥2% higher than placebo (N=245) in Study 1 were infusion-related reactions (LEQEMBI: 20%; placebo: 3%), headache (LEQEMBI: 14%; placebo: 10%), ARIA-E (LEQEMBI: 10%; placebo: 1%), cough (LEQEMBI: 9%; placebo: 5%), and diarrhea (LEQEMBI: 8%; placebo: 5%).

Accelerated Approval is based on Phase 2 data showing a reduction in amyloid-beta plaques in early AD patients treated with LEQEMBI™
Treatment with LEQEMBI should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical trials
For Print(PDF)(243KB)
TOKYO and CAMBRIDGE, Mass., January 7, 2023 – Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) and Biogen Inc. (Nasdaq: BIIB, Corporate headquarters: Cambridge, Massachusetts, CEO: Christopher A. Viehbacher, “Biogen”) announced today that under the Accelerated Approval Pathway the U.S. Food and Drug Administration (FDA) has approved lecanemab-irmb (Brand Name in the U.S.: LEQEMBI™) 100 mg/mL injection for intravenous use, a humanized immunoglobulin gamma 1 (IgG1) monoclonal antibody directed against aggregated soluble (“protofibril”)* and insoluble forms of amyloid beta (Aβ) for the treatment of Alzheimer’s disease (AD). The approval is based on Phase 2 data that demonstrated that LEQEMBI reduced the accumulation of Aβ plaque in the brain, a defining feature of AD. Using the recently published data from the large global confirmatory Phase 3 clinical trial, Clarity AD, Eisai will work quickly to file a Supplemental Biologics License Application (sBLA) to the FDA for approval under the traditional pathway.
INDICATION
LEQEMBI is indicated for the treatment of Alzheimer’s disease. Treatment with LEQEMBI should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical trials. There are no safety or effectiveness data on initiating treatment at earlier or later stages of the disease than were studied. This indication is approved under accelerated approval based on reduction in amyloid beta plaques observed in patients treated with LEQEMBI. Continued approval for this indication may be contingent upon verification of clinical benefit in a confirmatory trial.
DOSAGE AND ADMINISTRATION (Patient Selection, Dosing Instructions, Monitoring and Dosing Interruption for ARIA)
The recommended dosage of LEQEMBI is 10 mg/kg administered intravenously once every two weeks to eligible patients with confirmed presence of Aβ pathology prior to initiating treatment. Enhanced clinical vigilance for amyloid-related imaging abnormalities (ARIA) is recommended during the first 14 weeks of treatment with LEQEMBI. Baseline, recent (within one year) brain MRI prior to initiating treatment with LEQEMBI and periodic monitoring with MRI prior to the 5th, 7th, and 14th infusions should be obtained.
ADVERSE REACTIONS
The safety of LEQEMBI has been evaluated in 763 patients who received at least one dose of LEQEMBI in Study 201. The most common adverse reactions reported in at least 5% of patients treated with LEQEMBI 10 mg/kg biweekly (N=161) and at least 2% higher incidence than patients on placebo (N=245) were infusion-related reactions (LEQEMBI 20%; placebo 3%), headache (LEQEMBI 14%; placebo 10%), ARIA-E (LEQEMBI 10%; placebo 1%), cough (LEQEMBI, 9%; placebo, 5%) and diarrhea (LEQEMBI, 8%; placebo, 5%). The most common adverse reaction leading to discontinuation of LEQEMBI was infusion-related reactions that led to discontinuation in 2% (4/161) of patients treated with LEQEMBI compared to 1% (2/245) of patients on placebo.
CONCOMITANT ANTITHROMBOTIC MEDICATION AND OTHER RISK FACTORS FOR INTRACEREBRAL HEMORRHAGE
Patients were excluded from enrollment in Study 201 for baseline use of anticoagulant medications. Antiplatelet medications such as aspirin and clopidogrel were allowed. Patients who received LEQEMBI and an antithrombotic medication (aspirin, other antiplatelets, or anticoagulants) did not have an increased risk of ARIA-H compared to patients who received placebo and an antithrombotic medication. The majority of exposures to antithrombotic medications were to aspirin; few patients were exposed to other antiplatelet drugs or anticoagulants, limiting any meaningful conclusions about the risk of ARIA or intracerebral hemorrhage in patients taking other antiplatelet drugs or anticoagulants. Because intracerebral hemorrhages greater than 1 cm in diameter have been observed in patients taking LEQEMBI, additional caution should be exercised when considering the administration of antithrombotics or a thrombolytic agent (e.g., tissue plasminogen activator) to a patient already being treated with LEQEMBI. Additionally, patients were excluded from enrollment in Study 201 for the following risk factors for intracerebral hemorrhage: prior cerebral hemorrhage greater than 1 cm in greatest diameter, more than 4 microhemorrhages, superficial siderosis, evidence of vasogenic edema, evidence of cerebral contusion, aneurysm, vascular malformation, infective lesions, multiple lacunar infarcts or stroke involving a major vascular territory, and severe small vessel or white matter disease. Caution should be exercised when considering the use of LEQEMBI in patients with these risk factors.
“The FDA’s approval of LEQEMBI under the Accelerated Approval pathway is an important milestone in Eisai’s four decades of research in Alzheimer’s disease and reflects our continued commitment to alleviating the burden of Alzheimer’s disease for patients and their families. Eisai has made great efforts to understand the reality of the challenges and concerns facing patients and their families who are living in the various stages of Alzheimer’s disease, and we are incredibly pleased to offer LEQEMBI as a new treatment option to help with the tremendous unmet needs of this community,” said Haruo Naito, Chief Executive Officer at Eisai Co., Ltd. “The challenges of Alzheimer’s disease reach beyond medical implications for patients and considerations for their families, but also impact society as a whole through reduced productivity, elevated social costs and anxiety. Upon receiving this Accelerated Approval, we will focus on providing important information on proper usage of LEQEMBI to healthcare professionals. Eisai will also engage with various payers to provide access to LEQEMBI, offer a patient support program, and will do its utmost to complete submission for traditional approval as soon as possible to serve more people living with early Alzheimer’s disease.”
“The approval of LEQEMBI provides new hope to patients with Alzheimer’s disease. Patients at an early stage of the disease and their caregivers can now consider a new treatment option with their doctors. Our focus now is on the path forward, working alongside Eisai with the goal of making LEQEMBI available to patients who may benefit from this treatment as soon as possible,” said Christopher A. Viehbacher, President and Chief Executive Officer of Biogen. “This approval is also a recognition of the many scientists and doctors who have, over many years, patiently and persistently worked to find a treatment for this highly complex disease. Eisai and Biogen have collaborated for nearly a decade to advance research to improve the lives of those suffering from Alzheimer’s, and we know that this commitment must and will continue in the fight against Alzheimer’s disease.”
LEQEMBI’s ACCESS AND INITIATIVES TO SUPPORT PEOPLE LIVING WITH AD
The Eisai Patient Support Program offers several support programs to help patients and care partners. Dedicated Patient Navigators will work directly with patients and families to navigate treatment and coverage for eligible and appropriate patients and to help with what to expect regarding insurance coverage, co-pay and patient access programs. To learn more visit LEQEMBI.com(New Window), call 1-833-4-LEQEMBI (1-833-453-7362), Monday-Friday, 8 a.m. to 8 p.m. Eastern Time or fax to 1-833-770-7017.
In addition, to support access to LEQEMBI for certain financially disadvantaged patients, Eisai’s Patient Assistance Program (PAP) will provide LEQEMBI at no cost, for eligible uninsured and underinsured patients, including Medicare beneficiaries, who meet financial need and other program criteria.
Eisai looks forward to continuing to engage constructively with various payors, including the Centers for Medicare and Medicaid (CMS), TRICARE, the U.S. Veteran’s Health Administration and private health insurance companies to ensure appropriate beneficiaries have access to this new therapy. Currently, Medicare patients do not have access to LEQEMBI. Medicaid sole beneficiaries who are diagnosed by a healthcare professional with mild cognitive impairment or mild dementia stage of disease, and with confirmed presence of amyloid plaque in the brain will have access to LEQEMBI under the Medicaid program post accelerated approval, depending on individual state processes.
Eisai is developing a multi-faceted educational initiative to further advance the understanding in the AD healthcare community of the real-world management and monitoring of ARIA. This initiative, Understanding ARIA™, will provide resources and programs that will include peer-to-peer education, individual and group educational sessions and subject-matter-expert evaluation of historical case studies. Understanding ARIA will include engagements with leading experts in medical imaging as well as major professional societies. Initial resources will be available by January 2023.
LEQEMBI will be available during or before the week of January 23, 2023. Eisai announced the U.S. pricing and rationale for LEQEMBI today.

INDICATION, DOSAGE AND ADMINISTRATION, AND IMPORTANT SAFETY INFORMATION IN THE U.S.
INDICATION
LEQEMBI is indicated for the treatment of Alzheimer’s disease. Treatment with LEQEMBI should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical trials. There are no safety or effectiveness data on initiating treatment at earlier or later stages of the disease than were studied. This indication is approved under accelerated approval based on reduction in amyloid beta plaques observed in patients treated with LEQEMBI. Continued approval for this indication may be contingent upon verification of clinical benefit in a confirmatory trial.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Amyloid Related Imaging Abnormalities
- LEQEMBI can cause amyloid related imaging abnormalities-edema (ARIA-E) and -hemosiderin deposition (ARIA-H). ARIA-E can be observed on MRI as brain edema or sulcal effusions, and ARIA-H as microhemorrhage and superficial siderosis. ARIA is usually asymptomatic, although serious and life-threatening events, including seizure and status epilepticus, rarely can occur. Reported symptoms associated with ARIA may include headache, confusion, visual changes, dizziness, nausea, and gait difficulty. Focal neurologic deficits may also occur. Symptoms associated with ARIA usually resolve over time.
ARIA Monitoring and Dose Management Guidelines
- Obtain recent (within one year) brain magnetic resonance imaging (MRI) prior to initiating treatment with LEQEMBI. Obtain an MRI prior to the 5th, 7th, and 14th infusions.
- Recommendations for dosing in patients with ARIA-E and ARIA-H depend on clinical symptoms and radiographic severity. Depending on ARIA severity, use clinical judgment in considering whether to continue dosing, temporarily discontinue treatment, or permanently discontinue LEQEMBI.
- Enhanced clinical vigilance for ARIA is recommended during the first 14 weeks of treatment with LEQEMBI. If a patient experiences symptoms suggestive of ARIA, clinical evaluation should be performed, including MRI if indicated. If ARIA is observed on MRI, careful clinical evaluation should be performed prior to continuing treatment.
- There is no experience in patients who continued dosing through symptomatic ARIA-E or through asymptomatic, but radiographically severe, ARIA-E. There is limited experience in patients who continued dosing through asymptomatic but radiographically mild to moderate ARIA-E. There are limited data in dosing patients who experienced recurrent ARIA-E.
Incidence of ARIA
- In Study 1 (Study 201), symptomatic ARIA occurred in 3% (5/161) of LEQEMBI-treated patients. Clinical symptoms associated with ARIA resolved in 80% of patients during the period of observation.
- Including asymptomatic cases, ARIA was observed in LEQEMBI: 12% (20/161); placebo: 5% (13/245). ARIA-E was observed in LEQEMBI: 10% (16/161); placebo: 1% (2/245). ARIA-H was observed in LEQEMBI: 6% (10/161); placebo: 5% (12/245). There was no increase in isolated ARIA-H for LEQEMBI compared to placebo.
- Intracerebral hemorrhage >1 cm in diameter was reported after one treatment in LEQEMBI: 1 patient; placebo: zero patients. Events of intracerebral hemorrhage, including fatal events, in patients taking LEQEMBI have also been reported in other studies.
Apolipoprotein E ε4 (ApoE ε4) Carrier Status and Risk of ARIA
- In Study 1, 6% (10/161) of patients in the LEQEMBI group were ApoE ε4 homozygotes, 24% (39/161) were heterozygotes, and 70% (112/161) were noncarriers.
- The incidence of ARIA was higher in ApoE ε4 homozygotes than in heterozygotes and noncarriers among patients treated with LEQEMBI. Of the 5 LEQEMBI-treated patients who had symptomatic ARIA, 4 were ApoE ε4 homozygotes, 2 of whom experienced severe symptoms. An increased incidence of symptomatic and overall ARIA in ApoE ε4 homozygotes compared to heterozygotes and noncarriers in LEQEMBI-treated patients has been reported in other studies.
- The recommendations on management of ARIA do not differ between ApoE ε4 carriers and noncarriers.
- Consider testing for ApoE ε4 status to inform the risk of developing ARIA when deciding to initiate treatment with LEQEMBI.
Radiographic Findings
- The majority of ARIA-E radiographic events occurred early in treatment (within the first 7 doses), although ARIA can occur at any time and patients can have more than 1 episode. The maximum radiographic severity of ARIA-E in patients treated with LEQEMBI was mild in 4% (7/161) of patients, moderate in 4% (7/161) of patients, and severe in 1% (2/161) of patients. Resolution on MRI occurred in 62% of ARIA-E patients by 12 weeks, 81% by 21 weeks, and 94% overall after detection. The maximum radiographic severity of ARIA-H microhemorrhage in patients treated with LEQEMBI was mild in 4% (7/161) of patients and severe in 1% (2/161) of patients; 1 of the 10 patients with ARIA-H had mild superficial siderosis.
Concomitant Antithrombotic Medication and Other Risk Factors for Intracerebral Hemorrhage
- Patients were excluded from enrollment in Study 1 for baseline use of anticoagulant medications. Antiplatelet medications such as aspirin and clopidogrel were allowed. If anticoagulant medication was used because of intercurrent medical events that required treatment for ≤4 weeks, treatment with LEQEMBI was to be temporarily suspended.
- Most exposures to antithrombotic medications were to aspirin; few patients were exposed to other antiplatelet drugs or anticoagulants, limiting any meaningful conclusions about the risk of ARIA or intracerebral hemorrhage in patients taking other antiplatelet drugs or anticoagulants. Because intracerebral hemorrhages >1 cm in diameter have been observed in patients taking LEQEMBI, additional caution should be exercised when considering the administration of antithrombotics or a thrombolytic agent (e.g., tissue plasminogen activator) to a patient already being treated with LEQEMBI.
- Patients were excluded from enrollment in Study 1 for the following risk factors for intracerebral hemorrhage: prior cerebral hemorrhage >1 cm in greatest diameter, more than 4 microhemorrhages, superficial siderosis, evidence of vasogenic edema, evidence of cerebral contusion, aneurysm, vascular malformation, infective lesions, multiple lacunar infarcts or stroke involving a major vascular territory, and severe small vessel or white matter disease. Caution should be exercised when considering the use of LEQEMBI in patients with these risk factors.
Infusion-Related Reactions
- Infusion-related reactions were observed in LEQEMBI: 20% (32/161); placebo: 3% (8/245), and the majority of cases in LEQEMBI-treated patients (88%, 28/32) occurred with the first infusion. All infusion-related reactions were mild (56%) or moderate (44%) in severity. Infusion-related reactions resulted in discontinuations in 2% (4/161) of patients treated with LEQEMBI. Symptoms of infusion-related reactions included fever and flu-like symptoms (chills, generalized aches, feeling shaky, and joint pain), nausea, vomiting, hypotension, hypertension, and oxygen desaturation.
- After the first infusion, 38% of LEQEMBI-treated patients had transient decreased lymphocyte counts to <0.9 x109/L compared to 2% on placebo, and 22% of LEQEMBI-treated patients had transient increased neutrophil counts to >7.9 x109/L compared to 1% on placebo.
- In the event of an infusion-related reaction, the infusion rate may be reduced, or the infusion may be discontinued, and appropriate therapy initiated as clinically indicated. Prophylactic treatment with antihistamines, acetaminophen, nonsteroidal anti-inflammatory drugs, or corticosteroids prior to future infusions may be considered.
ADVERSE REACTIONS
- In Study 201, 15% of LEQEMBI-treated patients, compared to 6% of placebo-treated patients, stopped study treatment because of an adverse reaction. The most common adverse reaction leading to discontinuation of LEQEMBI was infusion-related reactions that led to discontinuation in 2% (4/161) of patients treated with LEQEMBI compared to 1% (2/245) of patients on placebo.
- The most common adverse reactions reported in ≥5% of patients treated with LEQEMBI (N=161) and ≥2% higher than placebo (N=245) in Study 1 were infusion-related reactions (LEQEMBI: 20%; placebo: 3%), headache (LEQEMBI: 14%; placebo: 10%), ARIA-E (LEQEMBI: 10%; placebo: 1%), cough (LEQEMBI: 9%; placebo: 5%), and diarrhea (LEQEMBI: 8%; placebo: 5%).

Notes to Editors
1. About LEQEMBITM (lecanemab-irmb)
LEQEMBITM (lecanemab-irmb) is a humanized immunoglobulin gamma 1 (IgG1) monoclonal antibody directed against aggregated soluble (protofibril) and insoluble forms of amyloid-beta (Aβ). LEQEMBI is indicated for the treatment of Alzheimer’s disease (AD) in the U.S. This indication is approved under accelerated approval based on reduction in Aβ plaques observed in patients treated with LEQEMBI. Continued approval for this indication may be contingent upon verification of clinical benefit in a confirmatory trial.
LEQEMBI is the result of a strategic research alliance between Eisai and BioArctic. Eisai has been initiated submission of data for BLA to the National Medical Products Administration (NMPA) of China in December 2022. Eisai plans to file for marketing authorization applications of lecanemab in Japan and Europe by the end of Eisai’s FY2022.
Since July 2020 Eisai’s Phase 3 clinical study (AHEAD 3-45) for individuals with preclinical AD, meaning they are clinically normal and have intermediate or elevated levels of amyloid in their brains, is ongoing. AHEAD 3-45 is conducted as a public-private partnership between the Alzheimer’s Clinical Trial Consortium that provides the infrastructure for academic clinical trials in AD and related dementias in the U.S, funded by the National Institute on Aging, part of the National Institutes of Health, Eisai and Biogen.
Since January 2022, the Tau NexGen clinical study for Dominantly Inherited AD (DIAD), that is conducted by Dominantly Inherited Alzheimer Network Trials Unit (DIAN-TU), led by Washington University School of Medicine in St. Louis, is ongoing. Eisai has completed a LEQEMBI subcutaneous bioavailability study, and subcutaneous dosing is currently being evaluated in the Clarity AD (Study 301) OLE.
2. About Amyloid-Related Imaging Abnormalities (ARIA)
ARIA is an important adverse event of amyloid-lowering therapies that is critical to monitor and manage during treatment. ARIA is most commonly seen as temporary swelling/effusion (ARIA-E) in areas of the brain that usually resolves over time. Some people may also have small spots of bleeding in or on the surface of the brain (ARIA-H) with the swelling. Although most people with ARIA-E do not have symptoms, some people may have symptoms such as headache, confusion, dizziness, vision changes and nausea.
3. About the Collaboration between Eisai and Biogen for AD
Eisai and Biogen have been collaborating on the joint development and commercialization of AD treatments since 2014. Eisai serves as the lead of LEQEMBI development and regulatory submissions globally with both companies co-commercializing and co-promoting the product and Eisai having final decision-making authority.
