consistency of efficacy assessments evaluated across various statistical methods

 

tokyo and cambridge, mass., nov.12, 2021 – eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) and biogen inc. (nasdaq: biib, corporate headquarters: cambridge, massachusetts, ceo: michel vounatsos, “biogen”) announced today results of sensitivity analyses evaluating the consistency of lecanemab efficacy results across multiple statistical models in patients with mild cognitive impairment (mci) due to alzheimer’s disease (ad) and mild ad (collectively known as early ad). this presentation was made by eisai at the 2021 clinical trials on alzheimer’s disease (ctad) conference, november 9-12, 2021 in boston, massachusetts and virtually.

in september 2021, eisai initiated a rolling submission of a biologics license application (bla) for lecanemab, an investigational anti-amyloid beta protofibril antibody, for the treatment of early ad, to the u.s. food and drug administration (fda) under the accelerated approval pathway.

study 201, a multicenter, double-blind, placebo-controlled, phase 2b trial conducted in 856 patients with early ad, evaluated key efficacy assessments, including clinical change on the alzheimer’s disease composite score (adcoms) at the primary endpoint of 12 months and at select key secondary endpoints, clinical dementia rating-sum-of-boxes (cdr-sb) and alzheimer’s disease assessment scale-cognitive subscale (adas-cog14) at 18 months. six sensitivity analyses across four statistical models (mixed model for repeated measures, disease progression model, natural cubic spline model, and quadratic mixed model) showed consistent positive lecanemab treatment effects for adcoms, cdr-sb and adas-cog14 at 18 months.

the primary endpoint was bayesian analysis of 12-month clinical change on adcoms with the goal to identify the most efficacious dose (ed90 dose). primary analysis was super-superiority over placebo by ≥25%: goal was 80% probability of ≥25% reduction in decline versus placebo. study achieved the goal of identifying smallest dose that achieved ≥90% of maximum treatment effect (10 mg/kg biweekly), i.e., the ed90 dose. at 12 months, ed90 dose had 64% probability of being super-superior to placebo by 25% reduction. at 12 months, ed90 dose had 98% probability superior to placebo. consistent treatment effect was observed at 18 months for adcoms (29% to 37%), cdr-sb (26.5% to 35%), and adas-cog (47% to 56%), with separation from placebo observed by six months for the top dose (10mg/kg biweekly) across all analyses.

“in study 201, lecanemab showed robust clearance of brain amyloid and slowing of clinical decline across several clinical and biomarker endpoints. this sensitivity analysis shows lecanemab clinical efficacy results across statistical models are consistent, reliable and further enhances our confidence in the clinical potential of this investigational therapy,” said michael irizarry, m.d., vice president, deputy chief clinical officer, neurology business group, eisai inc. “through our comprehensive research program, we will continue to advance the understanding of how this anti-amyloid beta protofibril antibody may play a role in the treatment of early and preclinical ad. in march 2021, eisai completed enrollment of 1,795 patients with early alzheimer’s disease in our confirmatory phase 3 clarity ad clinical study. the phase 3 clinical study, ahead 3-45, is currently exploring lecanemab’s safety and efficacy in individuals with preclinical ad.”

[notes to editors]

1. about lecanemab (ban2401)

lecanemab is an investigational humanized monoclonal antibody for alzheimer’s disease (ad) that is the result of a strategic research alliance between eisai and bioarctic. lecanemab selectively binds to neutralize and eliminate soluble, toxic amyloid-beta (aβ) aggregates (protofibrils) that are thought to contribute to the neurodegenerative process in ad. as such, lecanemab may have the potential to have an effect on disease pathology and to slow down the progression of the disease. with regard to the results from pre-specified analysis at 18 months of treatment, study 201 demonstrated reduction of brain aβ accumulation (p<0.0001) and slowing of disease progression measured by adcoms* (p<0.05) in early ad subjects. the study did not achieve its primary outcome measure** at 12 months of treatment. the study 201 open-label extension was initiated after completion of the core period and a gap period off treatment (average of 24 months) to evaluate safety and efficacy, and is underway.

eisai obtained the global rights to study, develop, manufacture and market lecanemab for the treatment of ad pursuant to an agreement concluded with bioarctic in december 2007. in march

2014, eisai and biogen entered into a joint development and commercialization agreement for lecanemab and the parties amended that agreement in october 2017. currently, lecanemab is being studied in a pivotal phase 3 clinical study in symptomatic early ad (clarity-ad), following the outcome of the phase 2 clinical study (study 201). in july 2020 the 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, was initiated. 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 alzheimer’s disease and related dementias in the u.s., funded by the national institute on aging, part of the national institutes of health, eisai and biogen.

* developed by eisai, adcoms (ad composite score) combines items from the adas-cog (alzheimer’s disease assessment scale-cognitive subscale), cdr (clinical dementia rating) and the mmse (mini-mental state examination) scales to enable a sensitive detection of changes in clinical functions of early ad symptoms and changes in memory.

tokyo and cambridge, mass., nov.12, 2021 – eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) and biogen inc. (nasdaq: biib, corporate headquarters: cambridge, massachusetts, ceo: michel vounatsos, “biogen”) announced a presentation about exploring the use of plasma-based biomarkers in the phase 3 ahead 3-45 study of lecanemab (ban2401), an investigational anti-amyloid beta (aβ) protofibril antibody. ahead 3-45 is the first preclinical alzheimer’s disease (ad) trial to use these biomarkers to detect ad pathology and potentially accelerate the screening process. this presentation was made by the alzheimer’s clinical trial consortium (actc) at the 2021 clinical trials on alzheimer’s disease (ctad) conference, november 9-12, 2021 in boston, massachusetts and virtually.

the ahead 3-45 clinical study will evaluate the efficacy of treatment with lecanemab in participants with preclinical ad and elevated amyloid and in participants with early preclinical ad and intermediate amyloid. in september 2021, eisai initiated a rolling submission of a biologics license application (bla) for lecanemab for the treatment of early ad, to the u.s. food and drug administration (fda) under the accelerated approval pathway.

the phase 3 ahead 3-45 study consists of two sister trials (a3 and a45) with specific dosing regimens tailored to baseline brain amyloid levels on screening pet scans for intermediate amyloid in a3 and for elevated amyloid in a45. in a first-of-a-kind approach in a preclinical trial for ad, the study will seek to determine the potential role of plasma-based biomarkers in the identification of cognitively unimpaired individuals most appropriate to move on to pet imaging, which is currently the standard of care to determine treatment approach.

blood samples will be collected at a brief initial visit to determine the aβ42/40 ratio, which has previously been shown to be a potentially reliable predictor of brain amyloid level and is used to determine eligibility to proceed to pet imaging. based on the pet imaging results, the participants are grouped into a3 or a45 trials.

as of october 18, 2021, data from 659 participants was available for analysis. adjusted aβ42/40 ratio demonstrated very good ability to predict amyloid pet eligibility (auc of 0.87) suggesting plasma screening has potential to substantially reduce number of pet scans needed to fully enroll a3 and a45.

“the screening process for ad can be time consuming and costly. there is a need to accelerate and improve the efficiency of identifying individuals who may be eligible for current and future ad treatments based on cognitive testing and confirmation of elevated amyloid in the brain,” said michael irizarry, m.d., vice president, deputy chief clinical officer, neurology business group, eisai inc. “eisai is forging new ground by incorporating plasma screening in a clinical study for individuals with preclinical ad. we are optimistic that this novel approach will help identify people with elevated brain amyloid, and reduce the need for diagnostic amyloid pet scans or spinal taps.”

tokyo and cambridge, mass, nov. 11, 2021 – eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) and biogen inc. (nasdaq: biib, corporate headquarters: cambridge, massachusetts, ceo: michel vounatsos, “biogen”) announced today results of new clinical, biomarker and safety assessments of brain amyloid reduction and five-year clinical status of people living with early alzheimer’s disease (ad) from the lecanemab phase 2b 201 and the open-label extension (ole) studies. the findings were presented and discussed in a late-breaking roundtable session with esteemed clinical researchers at the 2021 clinical trials on alzheimer’s disease (ctad) conference, november 9-12, 2021, in boston, massachusetts and virtually. eisai recently initiated a rolling submission of a biologics license application (bla) for lecanemab, an investigational anti-amyloid beta (aβ) protofibril antibody, for the treatment of early ad, to the u.s. food and drug administration (fda) under the accelerated approval pathway.

 

ole study explores biomarkers and clinical effects across five years

an ole with 10 mg/kg iv biweekly lecanemab dosing was implemented after analysis of the 18-month, core phase (study 201, ) with an intervening off-treatment period (gap period) ranging from 9-59 months (mean 24 months). the ole phase evaluated the effect of lecanemab on amyloid pet over 12 months of treatment, including earlier time points (3 and 6 months) than in the core phase (12 and 18 months). this study design provided the opportunity to explore the biomarker and clinical effects of stopping and restarting lecanemab across five years of disease trajectory.

 

amyloid reduction correlates with clinical benefit

the updated assessment of the ole phase showed that treatment with lecanemab resulted in reduction of brain amyloid levels in as early as 3 months based on ole data and robust clearance of amyloid plaque with more than 80% of participants (10/12) achieving amyloid negative status by 12-18 months of treatment as measured by pet (visual read). these results are consistent with core phase results. the 201 study core data suggested that clinical efficacy (adcoms) is correlated with amyloid reduction (pet suvr) at both the population (correlation coefficients=0.832, p-value=0.080) and subject levels (correlation coefficients=0.201, slope=0.199, p=0.036). amyloid pet levels were significantly reduced by quantitative assessment in newly treated ole subjects in as early as 3 months after initiation of treatment. additionally, the core data suggested that clinical efficacy is correlated with plasma aβ at both the population (correlation coefficients=-0.306, not significant) and subject levels (correlation coefficients=-0.208, slope=-3.957, p-value=0.050).

 

potential slowing of cognitive decline may suggest disease-modifying effect

the clinical treatment difference in study participants between lecanemab treatment and placebo at the end of core period is maintained after discontinued dosing over the 24-month gap period. the reduction of clinical decline of participants receiving the highest dose of lecanemab relative to placebo at the end of the 18-month, core period showed a difference of 0.05 in adcoms (placebo 0.19, lecanemab 0.14). this treatment difference of 0.10 in subjects who entered ole was maintained while off-treatment during the gap period up to the beginning of the ole (placebo 0.28, lecanemab 0.18). similar findings were observed for cdr-sb and adas-cog, although both groups continued to progress. this pattern of sustained treatment effect after stopping lecanemab, reflected in biomarkers as well amyloid pet, plasma aβ42/40 and ptau181 is consistent with a disease-modifying effect.

 

blood tests may be able to monitor lecanemab treatment effects

new results were presented for two new blood tests that were measured in the phase 2b and ole studies: plasma aβ42/40 ratio and plasma p-tau181. plasma aβ42/40 ratio changes suggested an inverse correlation with amyloid pet changes. both amyloid pet and blood aβ show correlation with adcoms at the population and individual levels in the core phase (pet correlation coefficients=0.832 population, 0.201 subject level and aβ plasma correlations coefficients:-0.306 population, -0.208 subject level). monitoring of treatment effects using plasma biomarkers may allow simple dose modification following robust amyloid removal (e.g., less frequent and/or lower dose).

 

safety profile with low incidence of aria-e and symptomatic aria rate in core and ole

consistent with the safety findings in the core period, lecanemab was well-tolerated with <10% incidence of aria-e at 10 mg/kg biweekly in the core and ole. the incidence of symptomatic aria-e was <2% in core and ole. this safety profile enables lecanemab to be initiated at the therapeutic dose without titration.

“the latest lecanemab findings provide greater insight into the time course and extent of amyloid reduction observed with lecanemab, and the relationship to clinical outcomes and blood-based biomarkers,” said lynn kramer, m.d., chief clinical officer, neurology business group, eisai. “the clarity ad phase 3 study in early ad, which completed enrollment of 1795 subjects in march, aims to verify these findings.”

the presentation video and slides will be available on the investors’ section of the eisai co., ltd. website by 10:00 p.m. u.s. est on november 11.

[notes to editors]

1. about lecanemab (ban2401)

lecanemab is an investigational humanized monoclonal antibody for alzheimer’s disease (ad) that is the result of a strategic research alliance between eisai and bioarctic. lecanemab selectively binds to neutralize and eliminate soluble, toxic amyloid-beta (aβ) aggregates (protofibrils) that are thought to contribute to the neurodegenerative process in ad. as such, lecanemab may have the potential to have an effect on disease pathology and to slow down the progression of the disease. with regard to the results from pre-specified analysis at 18 months of treatment, study 201 demonstrated reduction of brain aβ accumulation (p<0.0001) and slowing of disease progression measured by adcoms* (p<0.05) in early ad subjects. the study did not achieve its primary outcome measure** at 12 months of treatment. the study 201 open-label extension was initiated after completion of the core period and a gap period off treatment of 9-59 months (average of 24 months, n=180 from core study enrolled) to evaluate safety and efficacy, and is underway.

eisai obtained the global rights to study, develop, manufacture and market lecanemab for the treatment of ad pursuant to an agreement concluded with bioarctic in december 2007. in march 2014 eisai and biogen entered into a joint development and commercialization agreement for lecanemab and the parties amended that agreement in october 2017. currently, lecanemab is being studied in a pivotal phase 3 clinical study in symptomatic early ad (clarity-ad), following the outcome of the phase 2 clinical study (study 201). in july 2020 the 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, was initiated. 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 alzheimer’s disease and related dementias in the u.s, funded by the national institute on aging, part of the national institutes of health, eisai and biogen.

* developed by eisai, adcoms (ad composite score) combines items from the adas-cog (alzheimer’s disease assessment scale-cognitive subscale), cdr (clinical dementia rating) and the mmse (mini-mental state examination) scales to enable a sensitive detection of changes in clinical functions of early ad symptoms and changes in memory. the adcoms scale ranges from a score of 0.00 to 1.97, with higher score indicating greater impairment.

** an 80% or higher estimated probability of demonstrating 25% or greater slowing in clinical decline at 12 months treatment measured by adcoms from baseline compared to placebo.

eisai’s anti-microtubule binding region (mtbr) tau antibody e2814 previously selected as the first investigational therapy among anti-tau drugs for the dian-tu tau next generation trial

 

eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) announced today that the dominantly inherited alzheimer network trials unit (dian-tu), led by washington university school of medicine in st. louis, has an agreement with the u.s. food and drug administration (fda) and the european medicines agency (ema) to amend the clinical study (tau nexgen) design to include a background anti-amyloid agent. the tau nexgen clinical study was originally designed to focus on therapies that target tau. with increasing evidence from clinical studies showing that targeting amyloid can reduce biomarkers of alzheimer’s disease (ad), the tau nexgen clinical trial leaders selected eisai’s investigational anti-amyloid beta (aβ) protofibril antibody lecanemab as the background anti-amyloid agent.

the purpose of the tau nexgen study is to assess the safety, tolerability, biomarker and cognitive efficacy of investigational therapies in people who have an alzheimer’s disease-causing gene mutation. the study will evaluate if treatment with study drug slows the rate of progression of cognitive impairment and improves disease-related biomarkers.

people who have this genetic mutation of dominantly inherited alzheimer’s disease (diad) are known to develop ad and will likely develop symptoms at around the same age their affected parents did, often in their 50s, 40s or even 30s. in march 2021, the dian-tu selected anti-microtubule binding region (mtbr) tau antibody e2814, which was created from collaboration research between eisai and university college london, as the first investigational medicine among anti-tau drugs for the dian-tu tau study.

in the amended tau nexgen study, symptomatic participants will be administered lecanemab for six months before being randomly assigned to also receive the anti-tau drug or a placebo. since amyloid plaques accumulate before tau tangles in ad, this study design allows the researchers to assess whether amyloid removal clears the way for the anti-tau drug to function most effectively. pre-symptomatic participants will be randomly assigned to receive the anti-tau drug or a placebo for a year before beginning lecanemab administration. by staggering the drugs in this way, the researchers will be able to evaluate the effects of the anti-tau drug alone before assessing the effects of the two drugs together. the primary endpoint is a slowing of tau accumulation in the brain in symptomatic participants, as seen on pet brain scans. as a secondary endpoint, the researchers will evaluate whether the investigational therapies affect levels of a specific kind of tau — phosphorylated tau 217 — in the cerebrospinal fluid of pre-symptomatic participants. if these primary and secondary endpoints are positive in the analysis two years after the start of study, the study will be extended for another two years to assess whether the drug slows cognitive decline and has further effects on tau pathology.

“with growing evidence that removing amyloid plaques has biologically beneficial effects on amyloid and tau, we believe that targeting both alzheimer’s disease pathologies — amyloid plaques and tau tangles — at the same time can provide the highest chance of success,” said principal investigator randall j. bateman, m.d., director of dian-tu and the charles f. and joanne knight distinguished professor of neurology at washington university.

“eisai’s anti-mtbr tau antibody e2814 was chosen as the first investigational therapy among anti-tau drugs for the groundbreaking dominantly inherited alzheimer network trials unit tau nexgen, which was originally designed to target tau proteins. the growing body of evidence suggesting the removal of amyloid plaque slows cognitive decline is creating new possibilities to potentially fight this devastating disease. eisai is proud that our investigational anti-amyloid beta protofibril antibody lecanemab has been selected as the background anti-amyloid agent in this arm of the study,” said lynn kramer, m.d., faan, chief clinical officer, neurology business group, eisai co., ltd. “in our , lecanemab 10 mg/kg biweekly dosing without titration, demonstrated robust clearance of the brain amyloid plaques from early stage of administration and slowed cognitive decline in people living with early ad. encouragingly, the rate of amyloid-related imaging abnormalities-edema/effusion for this same dosing was 9.9% with less than 2% being symptomatic.”

eisai positions neurology as a key therapeutic area, and it will continue to create innovation in the development of novel medicines based on cutting-edge neurology research as it seeks to contribute further to improving the benefits of affected individuals and their families in diseases with high unmet needs, such as dementia including ad. our vision is clear: a world free of neurodegeneration.

eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) announced today the presentation of data from the company’s extensive alzheimer’s disease (ad) pipeline, including six oral presentations that will provide deeper insights into lecanemab’s potential as a treatment for early ad. eisai initiated a rolling submission of a biologics license application (bla) for lecanemab, an investigational anti-amyloid beta (aβ) protofibril antibody, for the treatment of early ad, to the u.s. food and drug administration (fda) under the accelerated approval pathway in september 2021. the lecanemab data and additional research findings from eisai’s robust ad pipeline will be featured in 10 presentations, including five late breaker oral presentations, at the 14th clinical trials on alzheimer’s disease (ctad) conference, november 9-12, 2021, in boston, massachusetts and virtually.

“the findings eisai will present at ctad provide scientific insights into the potential role of lecanemab in the treatment of early alzheimer’s disease as well as the relationship between clearance of amyloid-beta plaque from the brain, changes in blood-based biomarkers and clinical outcomes,” said michael irizarry, m.d., vice president, deputy chief clinical officer, neurology business group, eisai inc. “we are working to advance lecanemab and our other targeted investigational compounds as quickly as possible in our commitment to bringing solutions to patients and their families.”

the focus on ad has historically been on alleviating cognitive, functional, and behavioral symptoms, but there has been significant progress in understanding the biological mechanisms of the disease and eisai’s investigational pipeline aims to treat the range of underlying pathophysiology, including amyloid, tau and neurodegeneration.

“with lecanemab’s rolling bla submission to the fda under the accelerated approval pathway, completion of enrollment of 1,795 patients in the confirmatory phase 3 clarity ad clinical trial, initiation of a lecanemab subcutaneous dosing phase 1 study and the ongoing phase 3 ahead 3-45 study in people with pre-clinical alzheimer’s disease, it is an exciting time for lecanemab and eisai’s ad franchise,” said ivan cheung, chairman, eisai inc., senior vice president, president neurology business group and global alzheimer’s disease officer, eisai co., ltd. “we are optimistic about the promise lecanemab and other investigational compounds in our robust pipeline may have for people living with alzheimer’s disease.”

eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) and prism biolab co., ltd. (headquarters: kanagawa, president and ceo: dai takehara, “prism”) announced today that the  creb-binding protein (cbp) / β-catenin inhibitor e7386, a medium-molecular weight compound created through collaboration research between eisai and prism, has achieved the clinical poc (proof of concept).

eisai is conducting a phase i clinical study of e7386 monotherapy for solid tumors, and a phase ib clinical trial of e7386 plus lenvatinib mesylate (product name: lenvima®, “lenvatinib”), the orally available multiple receptor tyrosine kinase inhibitor discovered by eisai, for solid tumors including hepatocellular carcinoma. the achievement of the poc, which is defined in a collaborative research agreement between eisai and prism, was confirmed based on data such as antitumor activity and changes of biomarkers in these clinical trials.

the e7386 targets, β-catenin, is considered to be one of the undruggable targets that are particularly difficult to develop into drug discovery. β-catenin, along with cbp, which is also the target of e7386, is located at the downstream of the wnt signaling and regulates the wnt signaling-dependent transcription activity. e7386 is a cbp / β-catenin inhibitor that inhibits cbp and β-catenin protein-protein interactions and regulates the wnt signal-dependent gene expression. it is expected to suppress tumor growth dependent on the wnt signaling. 1 e7386 is also expected to release the suppression of tumor-infiltrating t cells by the wnt signaling activation, and to enhance the effect of immune checkpoint inhibitors1. the antitumor effect of e7386 alone and the combination of e7386 and anti-pd-1 antibody has been confirmed in a cancer-bearing mouse model.

based on the poc achievement, eisai has initiated a phase ib/ii clinical trial (study 201) of e7386 in combination with anti-pd-1 therapy pembrolizumab for solid tumors in japan.*

dr. takashi owa, senior vice president, president of oncology business group, at eisai said, “with achieving the poc, we are confident with the prospect of offering e7386 to patients as a cancer treatment. e7386 may overcome lenvatinib and pembrolizumab treatment resistances through its combination therapy with lenvatinib or pembrolizumab. eisai will accelerate clinical trials of e7386 in combination with lenvatinib or pembrolizumab, and do its utmost aiming to create new treatments for cancers with high unmet medical needs.”

dai takehara, president and ceo of prism commented, “the approval of the clinical poc for the e7386 demonstrates that prism’s drug discovery platform is an effective option for novel drug targets which have been considered difficult. we are grateful to eisai for advancing this development. we will continue to take on the challenge of targeting more novel targets, with the aim of providing new treatment to as many patients as possible.”

positive opinion granted for advanced renal cell carcinoma based on significant progression-free survival (pfs), overall survival (os) and objective response rate (orr) benefit compared to sunitinib in clear/keynote-581 trial

positive opinion granted for advanced endometrial carcinoma based on significant os and pfs benefit compared to chemotherapy in study 309/keynote-775 trial

 

tokyo and kenilworth, n.j., oct. 18, 2021 – eisai (headquarters: tokyo, ceo: haruo naito) and merck & co., inc., kenilworth, n.j., u.s.a. (known as msd outside the united states and canada) today announced that the committee for medicinal products for human use (chmp) of the european medicines agency has adopted positive opinions recommending approval of the combination of lenvima® (marketed as kisplyx® in the european union [eu]  for the treatment of advanced renal cell carcinoma [rcc]), the orally available multiple receptor tyrosine kinase inhibitor discovered by eisai, plus keytruda®, the anti-pd-1 therapy from merck & co., inc., kenilworth, n.j., u.s.a., for two different indications. one positive opinion is for the first-line treatment of adult patients with advanced rcc, and the other is for the treatment of adult patients with advanced or recurrent endometrial carcinoma (ec) who have disease progression on or following prior treatment with a platinum-containing therapy in any setting and are not candidates for curative surgery or radiation. decisions on the chmp’s recommendations will be given by the european commission for marketing authorization in the eu, and are expected in the fourth quarter of 2021. if approved, this would be the first combination of an anti-pd-1 therapy with a tyrosine kinase inhibitor approved for the treatment of two different types of cancer in the eu.

the positive chmp opinions are based on data from two pivotal phase 3 trials: clear (study 307)/keynote-581 evaluating the combination in adult patients with advanced rcc and study 309/keynote-775 evaluating the combination in certain patients with advanced ec.

in clear/keynote-581, lenvima plus keytruda demonstrated statistically significant improvements versus sunitinib in the efficacy outcome measures of overall survival (os), reducing the risk of death by 34% (hr=0.66 [95% ci, 0.49-0.88]; p=0.0049) versus sunitinib, and progression-free survival (pfs), reducing the risk of disease progression or death by 61% (hr=0.39 [95% ci, 0.32-0.49]; p<0.0001) with a median pfs of 23.9 months versus 9.2 months for sunitinib. additionally, the confirmed objective response rate was 71% (95% ci: 66-76) (n=252) for patients who received lenvima plus keytruda versus 36% with sunitinib (95% ci: 31-41) (n=129).

in study 309/keynote-775, lenvima plus keytruda demonstrated statistically significant improvements in the study’s dual efficacy outcome measures of os, reducing the risk of death by 38% (hr=0.62 [95% ci, 0.51-0.75]; p<0.0001) with a median os of 18.3 months versus 11.4 months for chemotherapy (investigator’s choice of doxorubicin or paclitaxel), and pfs, reducing the risk of disease progression or death by 44% (hr=0.56 [95% ci, 0.47-0.66]; p<0.0001), with a median pfs of 7.2 months versus 3.8 months for chemotherapy (investigator’s choice of doxorubicin or paclitaxel).

“keytruda plus lenvima demonstrated a survival benefit for advanced renal cell carcinoma in the first-line setting and represents an important potential new treatment option for these patients. additionally, keytruda plus lenvima is the first anti-pd-1 and tyrosine kinase inhibitor combination to demonstrate a survival benefit in advanced endometrial carcinoma patients, and the benefit was shown regardless of mismatch repair status,” said dr. gregory lubiniecki, vice president, clinical research, merck & co., inc., kenilworth, n.j., u.s.a. research laboratories. “we are pleased that the chmp has recognized the important role of the combination therapy in these difficult-to-treat cancers.”

“we appreciate the positive opinions rendered by the eu chmp recommending approval of lenvima plus keytruda in advanced renal cell carcinoma and advanced endometrial carcinoma, underscoring the potential significance of the outcomes observed in the clear/keynote-581 and study 309/keynote-775 trials” said dr. takashi owa, president, oncology business group at eisai. “we are grateful to the patients who participated in these studies, their families and clinicians. their commitment made these meaningful milestones possible.”

in clear/keynote-581, the most common adverse reactions (≥30%) for lenvima plus keytruda* were diarrhoea (61.8%), hypertension (51.5%) fatigue (47.1%), hypothyroidism (45.1%), decreased appetite (42.1%), nausea (39.6%), stomatitis (36.6%), proteinuria (33.0%), dysphonia (32.8%), and arthralgia (32.4%).

in study 309/keynote-775, the most common adverse reactions of these patients (≥20%) for lenvima plus keytruda* were hypertension (63%), diarrhoea (57%), hypothyroidism (56%), nausea (51%), decreased appetite (47%), vomiting (39%), fatigue (38%), decreased weight (35%), arthralgia (33%), proteinuria (29%), constipation (27%), headache (27%), urinary tract infection (27%), dysphonia (25%), abdominal pain (23%), asthenia (23%), palmar-plantar erythrodysaesthesia syndrome (23%), stomatitis (23%), anaemia (22%), and hypomagnesaemia (20%).

[notes to editors]

1. about the eisai and merck & co., inc., kenilworth, n.j., u.s.a. strategic collaboration

in march 2018, eisai and merck & co., inc., kenilworth, n.j., u.s.a., known as msd outside the united states and canada, through an affiliate, entered into a strategic collaboration for the worldwide co-development and co-commercialization of lenvima® (lenvatinib). under the agreement, the companies will jointly develop, manufacture and commercialize lenvima, both as monotherapy and in combination with keytruda® (pembrolizumab), the anti-pd-1 therapy from merck & co., inc., kenilworth, n.j., u.s.a.

in addition to ongoing clinical studies evaluating the keytruda plus lenvima combination across several different tumor types, the companies have jointly initiated new clinical studies through the leap (lenvatinib and pembrolizumab) clinical program and are evaluating the combination in 13 different tumor types across more than 20 clinical trials.

2. eisai’s focus on cancer

eisai focuses on the development of anticancer drugs, targeting the tumor microenvironment (with experience and knowledge from existing in-house discovered compounds) and the driver gene mutation and aberrant splicing (leveraging rna splicing platform) as areas (ricchi) where real patient needs are still unmet, and where eisai can aim to become a frontrunner in oncology. eisai aspires to discover innovative new drugs with new targets and mechanisms of action from these ricchi, with the aim of contributing to the cure of cancers.

keytruda® is a registered trademark of merck sharp & dohme corp., a subsidiary of merck & co., inc., kenilworth, n.j., u.s.a.

eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) announced today that it has received the award for excellence in corporate communications at the 37th annual corporate communications awards, hosted by the japan institute for social and economic affairs (tokyo, chairman: masakazu tokura), an affiliate of the japanese business federation (tokyo).

the corporate communications awards were established in 1984 with the aim of advancing the field by recognizing companies and individuals that practice excellent corporate communications. there are three awards: the award for excellence in corporate communications, outstanding leadership awards in corporate communications, and the outstanding merit awards.

the award for excellence in corporate communications received by eisai is given to the company that contribute to society by identifying what is expected and required of them by society, reflecting this in their management, and disseminating and communicating accurate information about their corporate activities to their stakeholders through public relations initiatives.

the award was presented to eisai in recognition of its efforts to promote understanding of dementia, which has become a social issue, by providing not only information on the status of new drug development, but also on the latest findings on the pathological condition of the disease and the social burden of nursing care, as well as efforts to promote understanding among stakeholders through study sessions for scientific and medical journalists and providing easy-to-understand explanations of difficult science, thereby making a significant contribution to increase the benefits of patients and their families in line with its corporate philosophy of human health care (hhc).

eisai’s corporate philosophy is to give first thought to patients and their families, and increase the benefits that health care provides, and eisai calls this philosophy the “human health care (hhc)” philosophy, in one word. in the new medium-term business plan “eway future & beyond” started in fy2021, based on the hhc philosophy, eisai aims to remove the anxiety of “the people”, including not only patients but also society at large, by delivering not only pharmaceutical products but also solutions to the people. in order to realize the hhc philosophy, we will make further contributions to increase the benefits to “the people” by enhancing corporate value through public relations activities.
