FDA Grants Standard Approval for Leqembi (lecanemab-irmb) for the Remedy of Alzheimer’s Sickness


TOKYO and CAMBRIDGE, Mass., July 06, 2023 (GLOBE NEWSWIRE) — Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) and Biogen Inc. (Nasdaq: BIIB, Firm headquarters: Cambridge, Massachusetts, CEO: Christopher A. Viehbacher, “Biogen”) launched in the meanwhile that the U.S. Meals and Drug Administration (FDA) has licensed the supplemental Biologics License Software program (sBLA) supporting the traditional approval of Leqembi® (lecanemab-irmb) 100 mg/mL injection for intravenous use, making Leqembi the first and solely licensed remedy confirmed to chop again the velocity of sickness improvement and to gradual cognitive and purposeful decline in adults with Alzheimer’s sickness (AD). Leqembi demonstrated clinically important slowing of cognitive and purposeful decline in a affected individual group generalizable to U.S. Medicare beneficiaries, which included a mix of racial and ethnic groups, victims with widespread comorbid conditions, concomitant medicines and victims with light cognitive impairment (MCI) due to AD or light AD. Remedy with Leqembi have to be initiated in victims with MCI or light dementia stage of sickness, (collectively often called early AD) the inhabitants by which remedy was initiated in medical trials.

Leqembi’s typical approval depends on Half 3 information from Eisai’s huge, world Readability AD medical trial, by which Leqembi met its main endpoint and all key secondary endpoints with statistically necessary outcomes and confirmed the medical benefit of Leqembi. The primary endpoint was the worldwide cognitive and purposeful scale, Scientific Dementia Rating Sum of Packing containers (CDR-SB). Leqembi remedy decreased medical decline on CDR-SB by 27% at 18 months as compared with placebo. Furthermore, the secondary endpoint of AD Cooperative Analysis-Actions of Every day Residing Scale for Delicate Cognitive Impairment (ADCS MCI-ADL), as measured by of us caring for victims with AD, well-known a statistically necessary benefit of 37%. This measures the flexibleness of victims to carry out independently, along with with the power to robe, feed themselves and participate in neighborhood actions. Full outcomes of the Readability AD look at have been launched on the Scientific Trials on Alzheimer’s Sickness (CTAD) 2022 conference and concurrently revealed inside the peer-reviewed medical journal The New England Journal of Treatment on November 29, 2022.

Importantly, following FDA’s typical approval of Leqembi, CMS confirmed that broader safety of Leqembi is now on the market and launched further particulars on the registry, along with the easy-to-use information submission course of. The CMS-facilitated registry is now on the market for healthcare professionals to submit required affected individual information to CMS. Eisai is comfortable that Medicare will cowl this mandatory treatment for acceptable victims. This may facilitate reimbursement for and entry to Leqembi all through a broad range of healthcare settings within the USA.

“Instantly, the FDA licensed Leqembi beneath the traditional approval pathway, making Leqembi the first and solely licensed anti-amyloid Alzheimer’s sickness remedy confirmed to chop again the velocity of sickness improvement and to gradual cognitive impairment inside the early and delicate dementia ranges of the sickness. As a evaluation and development-focused agency primarily based totally on our hhc (human nicely being care) thought, we’re proud that the outcomes of Eisai’s AD evaluation over the earlier 40 years have been acknowledged and delivered to of us residing with this sickness within the USA,” talked about Haruo Naito, Chief Govt Officer at Eisai. “Alzheimer’s sickness is a progressive, lethal sickness that enormously impacts not solely the oldsters residing with it, however as well as their members of the family, care companions and society. We proceed to work to create broad and simple entry to Leqembi for victims and to assist evaluation and remedy on the early stage of the sickness. Eisai will diligently work to educate physicians on the safe and acceptable use of Leqembi to maximise its revenue to of us residing with early AD and their households.”

“Instantly marks a breakthrough inside the remedy of Alzheimer’s sickness, and we’re proud to be on the forefront of ushering in a model new interval of advances for a sickness that was beforehand considered untreatable. We want to particular our trustworthy appreciation to people who have labored tirelessly to find a remedy for this unrelenting sickness, with out whom this progress would not be potential,” talked about Christopher A. Viehbacher, President and Chief Govt Officer of Biogen. “Our focus is now on the path forward, working alongside Eisai with the intention of setting up Leqembi accessible to eligible victims as shortly as potential.”

Leqembi is a humanized immunoglobulin gamma 1 (IgG1) monoclonal antibody directed in the direction of aggregated soluble (protofibril*) and insoluble forms of amyloid beta (Aβ). Critically, Leqembi targets and clears primarily essentially the most neurotoxic kind of Aβ that always accumulates along with removes the prevailing plaques to take care of this progressive, persistent sickness. In June 2023, the FDA’s Peripheral and Central Nervous System Medication (PCNS) advisory committee voted unanimously that the data from Eisai’s Readability AD medical trial confirmed the medical benefit of Leqembi for the remedy of AD. Committee members moreover confirmed the overall risk-benefit of Leqembi. On January 6, 2023, Leqembi was licensed by the FDA beneath the accelerated approval pathway.

Eisai has developed and deployed Understanding ARIA™, a multi-faceted educational initiative to extra advance understanding inside the AD healthcare neighborhood of the real-world administration and monitoring of amyloid-related imaging abnormalities (ARIA). In collaboration with specialists inside the topic of medical imaging along with major expert societies, Understanding ARIA™ presents property and functions that embody peer-to-peer coaching, specific individual and group educational intervals and subject-matter-expert evaluation of historic case analysis.

Eisai is devoted to creating positive that acceptable victims have entry to Leqembi and has established a Affected individual Assist Program to supply Leqembi with out cost, for eligible uninsured and underinsured victims, along with Medicare beneficiaries, who meet financial need and totally different program requirements. Furthermore, Eisai presents affected individual assist for bettering entry via Leqembi Affected individual Navigators, who will current particulars about accessing Leqembi, help victims and their households understand their insurance coverage protection safety and selections, and set up financial assist functions for eligible victims. People inside the U.S. may be taught further about these corporations by visiting Leqembi.com, calling 1-833-4-Leqembi (1-833-453-7362), Monday-Friday, 8 a.m. to eight p.m. Jap Time or faxing an enrollment type to 1-833-770-7017.

Leqembi is indicated for the remedy of Alzheimer’s sickness. Remedy with Leqembi have to be initiated in victims with light cognitive impairment or light dementia stage of sickness, the inhabitants by which remedy was initiated in medical trials.



  • Monoclonal antibodies directed in the direction of aggregated forms of amyloid beta, along with Leqembi, might trigger amyloid related imaging abnormalities (ARIA), characterised as ARIA with edema (ARIA-E) and ARIA with hemosiderin deposition (ARIA-H). Incidence and timing of ARIA fluctuate amongst treatments. ARIA usually occurs early in remedy and is generally asymptomatic, although crucial and life-threatening events rarely can occur. Extreme intracerebral hemorrhages >1 cm, a couple of of which have been lethal, have been seen in victims dealt with with this class of medicines.
    • Apolipoprotein E ε4 (ApoE ε4) Homozygotes: Victims who’re ApoE ε4 homozygotes (roughly 15% of Alzheimer’s sickness victims) dealt with with this class of medicines, along with Leqembi, have the following incidence of ARIA, along with symptomatic, crucial, and excessive radiographic ARIA, as compared with heterozygotes and noncarriers. Testing for ApoE ε4 standing have to be carried out earlier to initiation of remedy to inform the possibility of making ARIA. Earlier to testing, prescribers ought to speak about with victims the possibility of ARIA all through genotypes and the implications of genetic testing outcomes. Prescribers ought to tell victims that if genotype testing simply is not carried out, they’ll nonetheless be dealt with with Leqembi; nonetheless, it could’t be determined in the event that they’re ApoE ε4 homozygotes and at bigger hazard for ARIA.
  • Bear in mind the benefit of Leqembi for the remedy of Alzheimer’s sickness and potential hazard of nice opposed events associated to ARIA when deciding to impress remedy with Leqembi


Leqembi is contraindicated in victims with crucial hypersensitivity to lecanemab-irmb or to any of the excipients of Leqembi. Reactions have included angioedema and anaphylaxis.



  • Leqembi might trigger ARIA-E and ARIA-H. ARIA-E could also be seen on MRI as thoughts edema or sulcal effusions, and ARIA-H as microhemorrhage and superficial siderosis. ARIA can occur spontaneously in victims with Alzheimer’s sickness. ARIA-H associated to monoclonal antibodies directed in the direction of aggregated forms of beta amyloid normally occurs in affiliation with an incidence of ARIA-E. ARIA-H and ARIA-E can occur collectively. ARIA usually occurs early in remedy and is generally asymptomatic, although crucial and life-threatening events, along with seizure and standing epilepticus, rarely can occur. Reported indicators associated to ARIA may embody headache, confusion, seen changes, dizziness, nausea, and gait difficulty. Focal neurologic deficits could occur. Indicators associated to ARIA usually resolve over time.

ARIA Monitoring and Dose Administration Pointers

  • Pay money for newest baseline thoughts magnetic resonance imaging (MRI) earlier to initiating remedy with Leqembi. Pay money for an MRI earlier to the fifth, seventh and 14th infusions.
  • Options for dosing in victims with ARIA-E and ARIA-H rely on medical indicators and radiographic severity. Counting on ARIA severity, use medical judgment in considering whether or not or to not proceed dosing, shortly discontinue remedy, or fully discontinue Leqembi.
  • Enhanced medical vigilance for ARIA is basically helpful by means of the primary 14 weeks of remedy with Leqembi. If a affected individual experiences indicators suggestive of ARIA, medical evaluation have to be carried out, along with MRI if indicated. If ARIA is seen on MRI, cautious medical evaluation have to be carried out earlier to persevering with remedy.
  • There is not a experience in victims who continued dosing via symptomatic ARIA-E or via asymptomatic, nonetheless radiographically excessive, ARIA-E. There’s restricted experience in victims who continued dosing via asymptomatic nonetheless radiographically light to affordable ARIA-E. There are restricted information in dosing victims who expert recurrent ARIA-E.

Incidence of ARIA

  • In Analysis 2, symptomatic ARIA occurred in 3% (29/898) of Leqembi-treated victims. Extreme indicators associated to ARIA have been reported in 0.7% (6/898) of victims dealt with with Leqembi. Scientific indicators associated to ARIA resolved in 79% (23/29) of victims by means of the interval of comment.
  • Along with asymptomatic radiographic events, ARIA was seen in Leqembi: 21% (191/898); placebo: 9% (84/897). ARIA-E was seen in Leqembi: 13% (113/898); placebo: 2% (15/897). ARIA-H was seen in Leqembi: 17% (152/898); placebo: 9% (80/897). There was no enhance in isolated ARIA-H for Leqembi vs placebo.

ApoE ε4 Service Standing and Menace of ARIA

  • In Analysis 2, 16% (141/898) of victims inside the Leqembi arm have been ApoE ε4 homozygotes, 53% (479/898) have been heterozygotes, and 31% (278/898) have been noncarriers.
  • The incidence of ARIA was bigger in ApoE ε4 homozygotes (Leqembi: 45%; placebo: 22%) than in heterozygotes (Leqembi: 19%; placebo: 9%) and noncarriers (Leqembi: 13%; placebo: 4%). Amongst victims dealt with with Leqembi, symptomatic ARIA-E occurred in 9% of ApoE ε4 homozygotes in distinction with 2% of heterozygotes and 1% noncarriers. Extreme events of ARIA occurred in 3% of ApoE ε4 homozygotes, and roughly 1% of heterozygotes and noncarriers.
  • The strategies on administration of ARIA do not differ between ApoE ε4 carriers and noncarriers.

Radiographic Findings

  • Practically all of ARIA-E radiographic events occurred early in remedy (all through the primary 7 doses), although ARIA can occur at any time and victims can have better than 1 episode. The utmost radiographic severity of ARIA-E in victims dealt with with Leqembi was light in 4% (37/898), affordable in 7% (66/898), and excessive in 1% (9/898). Determination on MRI occurred in 52% of ARIA-E victims by 12 weeks, 81% by 17 weeks, and 100% basic after detection. The utmost radiographic severity of ARIA-H microhemorrhage in Leqembi-treated victims was light in 9% (79/898), affordable in 2% (19/898), and excessive in 3% (28/898) of victims; superficial siderosis was light in 4% (38/898), affordable in 1% (8/898) , and excessive in 0.4% (4/898). Amongst Leqembi-treated victims, the velocity of maximum radiographic ARIA-E was highest in ApoE ε4 homozygotes 5% (7/141), as compared with heterozygotes 0.4% (2/479) or noncarriers 0% (0/278). Amongst Leqembi-treated victims, the velocity of maximum radiographic ARIA-H was highest in ApoE ε4 homozygotes 13.5% (19/141), as compared with heterozygotes 2.1% (10/479) or noncarriers 1.1% (3/278).

Intracerebral Hemorrhage

  • Intracerebral hemorrhage >1 cm in diameter was reported in 0.7% (6/898) of victims in Analysis 2 after remedy with Leqembi as compared with 0.1% (1/897) on placebo. Lethal events of intracerebral hemorrhage in victims taking Leqembi have been reported.

Concomitant Antithrombotic Treatment:

  • In Analysis 2, baseline use of antithrombotic treatment (aspirin, totally different antiplatelets, or anticoagulants) was allowed if the affected individual was on a safe dose. Practically all of exposures to antithrombotic medicines have been to aspirin. Antithrombotic medicines did not enhance the possibility of ARIA with Leqembi. The incidence of intracerebral hemorrhage was 0.9% (3/328 victims) in victims taking Leqembi with a concomitant antithrombotic treatment on the time of the event as compared with 0.6% (3/545 victims) in people who did not get hold of an antithrombotic. Victims taking Leqembi with an anticoagulant alone or combined with an antiplatelet treatment or aspirin had an incidence of intracerebral hemorrhage of two.5% (2/79 victims) as compared with none in victims who acquired placebo.
  • Because of intracerebral hemorrhages >1 cm in diameter have been seen in victims taking Leqembi, additional warning have to be exercised when considering the administration of anticoagulants or a thrombolytic agent (e.g., tissue plasminogen activator) to a affected individual already being dealt with with Leqembi.

Completely different Menace Components for Intracerebral Hemorrhage:

  • Victims have been excluded from enrollment in Analysis 2 for findings on neuroimaging that indicated an elevated hazard for intracerebral hemorrhage. These included findings suggestive of cerebral amyloid angiopathy (prior cerebral hemorrhage >1 cm in greatest diameter, >4 microhemorrhages, superficial siderosis, vasogenic edema) or totally different lesions (aneurysm, vascular malformation) that will most likely enhance the possibility of intracerebral hemorrhage. The presence of an ApoE ε4 allele may be associated to cerebral amyloid angiopathy, which has an elevated hazard for intracerebral hemorrhage. Warning have to be exercised when considering the utilization of Leqembi in victims with components that time out an elevated hazard for intracerebral hemorrhage and particularly for victims who needs to be on anticoagulant treatment.

Hypersensitivity reactions, along with angioedema, bronchospasm, and anaphylaxis, have occurred in Leqembi-treated victims. Promptly discontinue the infusion upon the first comment of any indicators or indicators per a hypersensitivity response, and provoke acceptable treatment.


  • In Analysis 2, infusion-related reactions have been seen in Leqembi: 26% (237/898); placebo: 7% (66/897), and almost all of circumstances in Leqembi-treated victims (75%, 178/237) occurred with the first infusion. Infusion-related reactions have been largely light (69%) or affordable (28%) in severity. Infusion-related reactions resulted in discontinuations in 1% (12/898) of Leqembi-treated victims. Indicators of infusion-related reactions included fever and flu-like indicators (chills, generalized aches, feeling shaky, and joint ache), nausea, vomiting, hypotension, hypertension, and oxygen desaturation.
  • Throughout the event of an infusion-related response, the infusion cost may be decreased, or the infusion may be discontinued, and acceptable treatment initiated as clinically indicated. Prophylactic remedy with antihistamines, acetaminophen, nonsteroidal anti-inflammatory medication, or corticosteroids earlier to future infusions may be considered.


  • In Analysis 2, the commonest opposed reactions leading to discontinuation of Leqembi was ARIA-H microhemorrhages that led to discontinuation in 2% (15/898) of victims dealt with with Leqembi as compared with <1% (1/897) of victims on placebo.
  • In Analysis 2, the commonest opposed reactions reported in ≥5% of victims dealt with with Leqembi (N=898) and ≥2% bigger than placebo (N=897) have been infusion-related reactions (Leqembi: 26%; placebo: 7%), ARIA-H (Leqembi: 14%; placebo: 8%), ARIA-E (Leqembi: 13%; placebo: 2%), headache (Leqembi: 11%; placebo: 8%), superficial siderosis of central nervous system (Leqembi: 6%; placebo: 3%), rash (Leqembi: 6%; placebo: 4%), and nausea/vomiting (Leqembi: 6%; placebo: 4%).
