[notes to editors]
1. about lemborexant
lemborexant is a novel investigational small molecule compound, discovered and developed by eisai in-house scientists, that inhibits orexin signaling by binding competitively to both orexin receptor subtypes (orexin receptor 1 and 2). in individuals with normal daily sleep-wake rhythms, orexin signaling is believed to promote periods of wakefulness. in individuals with sleep-wake disorders, it is possible that orexin signaling that regulates wakefulness is not functioning normally, suggesting that inhibiting inappropriate orexin signaling may enable initiation and maintenance of sleep. additionally, a phase 2 clinical study of lemborexant in patients with irregular sleep-wake rhythm disorder (iswrd) and mild to moderate alzheimer’s dementia is underway.

eisai co., ltd. (headquarters: tokyo, ceo: haruo naito, “eisai”) announced today that in the 8th meeting of the data safety monitoring board (dsmb) for the global phase iii clinical studies (mission ad) on the investigational oral bace (beta amyloid cleaving enzyme) inhibitor elenbecestat (development code: e2609) in early alzheimer’s disease (ad), the dsmb reviewed safety data including the potential for decline in cognition, and recommended the continuation of the studies. elenbecestat is being jointly developed by eisai and biogen inc. (headquarters: cambridge, massachusetts, united states).

the phase iii clinical trial program for elenbecestat (mission ad) consists of two global phase iii clinical studies with identical protocols, mission ad1 (study 301) and mission ad2 (study 302). both studies are multicenter, placebo-controlled, double-blind, parallel-group phase iii clinical studies aiming to assess the efficacy and safety of elenbecestat for treatment in patients with mild cognitive impairment (mci) due to ad or mild ad dementia (collectively known as early ad) with confirmed amyloid pathology in the brain. patients are allocated randomly to receive either 50 mg of elenbecestat or placebo daily during the treatment period of 24 months, and the primary endpoint utilizes the clinical dementia rating sum of boxes (cdr-sb).
enrollment in mission ad is scheduled to be completed in march 2019.

eisai aims to create innovative medicines for alzheimer’s disease as soon as possible in order to further contribute to addressing the unmet medical needs of, as well as potentially increasing the benefits provided to, patients and their families.

1. about elenbecestat (generic name, development code: e2609)
discovered by eisai, elenbecestat is an investigational next-generation oral candidate for the treatment of alzheimer’s disease (ad) that inhibits bace (beta amyloid cleaving enzyme). by inhibiting bace, a key enzyme in the production of aβ peptides, elenbecestat reduces aβ production, and by reducing amyloid plaque formations in the brain, exerts disease modifying effects of potentially slowing the progression of ad. currently, two global phase iii clinical studies (mission ad1/2) of elenbecestat in early ad including mild cognitive impairment (mci) due to ad or the mild ad are underway. in addition, the u.s. food and drug administration (fda) has granted fast track designation for the development of elenbecestat, a process allowing priority reviews by the fda for drugs deemed as having potential to treat serious conditions and tackle key unmet medical needs.

  

2. about mission ad
initiated in october 2016, the phase iii clinical trial program for elenbecestat (mission ad) consists of two global phase iii clinical studies with identical protocols, mission ad1 (study 301) and mission ad2 (study 302), and is being conducted at over 400 sites in 30 countries worldwide. both studies are multicenter, placebo-controlled, double-blind, parallel-group phase iii clinical studies aiming to assess the efficacy and safety of elenbecestat for treatment in patients with mild cognitive impairment (mci) due to ad or mild ad dementia (collectively known as early ad) with confirmed amyloid pathology in the brain. patients are allocated randomly to receive either 50 mg of elenbecestat or placebo daily during the treatment period of 24 months, and the primary endpoint utilizes the clinical dementia rating sum of boxes (cdr-sb).

tokyo and stamford, conn. – march 12, 2019 – eisai co., ltd. (ceo: haruo naito, “eisai”) and imbrium therapeutics l.p. (imbrium therapeutics), a clinical-stage biopharmaceutical company and operating subsidiary of purdue pharma, l.p. (president and ceo: craig landau, md) today announced that the u.s. food and drug administration (fda) has accepted for review the new drug application (nda) for lemborexant, an investigational agent being studied for the treatment of insomnia, a sleep-wake disorder. a prescription drug user fee act (pdufa) date is set for december 27, 2019.

the nda submission was based on data from the clinical development program including two pivotal phase 3 studies of lemborexant – sunrise 1 (study 304) and sunrise 2 (study 303).

• sunrise 1: a one-month phase 3 clinical study to evaluate the efficacy and safety of lemborexant versus placebo and versus an active comparator (zolpidem tartrate extended release, “zolpidem er”) in 1,006 patients 55 years and older (45 percent of all patients were aged 65 years and older) with insomnia disorder. this study assessed sleep latency (using latency to persistent sleep; primary objective); sleep efficiency and wake after sleep onset (effect on maintaining sleep; key secondary objectives) objectively using polysomnography, and achieved its primary and key secondary objectives. the most common adverse events (aes) reported in the lemborexant arms were headache and somnolence.¹

• sunrise 2: a 12-month placebo-controlled (first six months) phase 3 clinical study to evaluate the long-term efficacy and safety of lemborexant in 949 adult patients (18 to 88 years of age) with insomnia disorder. this study evaluated subjective (patient-reported) sleep onset latency (primary objective), sleep efficiency, and wake after sleep onset (key secondary objectives) using sleep diaries, and achieved its pre-specified primary and key secondary efficacy objectives. the most common aes reported in the lemborexant arms were somnolence, nasopharyngitis, headache, and influenza.²

“our ultimate goal for the development of a sleep-wake treatment is to bring to patients living with insomnia a new option that has the potential to improve their ability to fall asleep, stay asleep and wake the next morning without impairment,” said lynn kramer, md, chief clinical officer and chief medical officer, neurology business group, eisai. “this milestone for lemborexant brings us one step closer to addressing unmet needs for millions of patients who experience insomnia.”

“insomnia, a disorder of sleep quality and quantity, causes significant impairment in daily functioning and has long-term consequences for health and well-being,”³ said john renger, phd, vice president, head of research & development and regulatory affairs, imbrium therapeutics. “we are committed to working with our partner eisai to make this investigational treatment available to patients, pending regulatory approval.”

lemborexant is being jointly developed by eisai and imbrium therapeutics for the treatment of multiple sleep-wake disorders, including insomnia disorder. information about ongoing clinical studies is available at clinicaltrials.gov.

eisai and imbrium therapeutics are striving to address new unmet medical needs and to improve the lives of patients and their families.

this release discusses investigational uses of an agent in development and is not intended to convey conclusions about efficacy or safety. there is no guarantee that such an investigational agent will successfully complete clinical development or gain health authority approval.

2. about sunrise 1 (study 304)¹
sunrise 1 was a multicenter, randomized, double-blind, placebo-controlled, active comparator, parallel-group study evaluating the efficacy and safety of lemborexant in 1,006 male or female adult patients 55 years and older (45 percent of patients were 65 years and older) with insomnia disorder conducted in north america and europe. sunrise 1 included a pre-randomization phase of up to 35 days (including a two-week placebo run-in period) and a randomization phase comprised of a 30-day treatment period and a minimum two-week period without treatment prior to the end-of-study visit. in this study, patients were randomized to receive placebo or one of three treatment regimens (lemborexant 5 mg, lemborexant 10 mg, zolpidem er 6.25 mg).

the primary objective for sunrise 1 was to demonstrate using polysomnography that lemborexant at either the 5 mg or 10 mg dose is superior to placebo on objective sleep onset, as measured by latency to persistent sleep after the last two nights of one month of treatment. key secondary objectives included change from baseline in sleep efficiency and wake after sleep onset (waso) for both lemborexant doses compared to placebo, and waso in the second half of the night (waso2h) for both lemborexant doses compared to zolpidem er, each after the last two nights of one month of treatment.

3. about sunrise 2 (study 303)²
sunrise 2 was a 12-month multicenter, global, randomized, controlled, double-blind, parallel-group study of the efficacy and safety of lemborexant in 949 male or female adult participants 18 to 88 years of age with insomnia disorder. sunrise 2 included a pre-randomization phase of up to 35 days (including a two-week placebo run-in period) and a randomization phase comprised of a six-month placebo-controlled treatment period, a six-month period of active-only treatment and a two-week period without treatment prior to the end-of-study visit. in this study, during the placebo-controlled treatment period, patients were randomized to receive placebo or one of two treatment regimens (lemborexant 5 mg or 10 mg). during the active-only treatment period, patients who received placebo during the first period were re-randomized to receive lemborexant 5 mg or 10 mg. patients who received active treatment during the first period continued on the treatment to which they were originally randomized.

the primary objective was change from baseline in subjective sleep onset latency after six months of placebo-controlled treatment using patient reported (subjective) sleep diaries. key secondary endpoints were change from baseline in subjective sleep efficiency and subjective wake after sleep onset (swaso) by using patient reported (subjective) sleep diaries for both lemborexant doses after six months of placebo-controlled treatment.

4. about sleep disorders
population studies show that sleep disorders affect many more people worldwide than previously thought.⁴ insomnia disorder is the most common sleep disorder affecting approximately 30 percent of the adult population worldwide.^4,5 insomnia disorder is characterized by difficulty falling asleep, staying asleep or both, despite an adequate opportunity to sleep, which can lead to daytime consequences such as fatigue, difficulty concentrating and irritability.^3,6

sleeping well is essential for good health, including brain health. poor sleep is associated with a wide range of health consequences, including an increased risk of hypertension, accidental injury, diabetes, obesity, depression, heart attack, stroke and dementia, as well as adverse effects on mood and behavior.^3,7

experimental studies in animals and humans provide evidence of associations between sleep and disease risk factors, diseases and mortality.⁸ studies suggest an optimal sleep duration between seven and eight hours.⁹

women are 1.4 times more likely than men to suffer from insomnia.¹⁰ older adults also have higher prevalence of insomnia; aging is often accompanied by changes in sleep patterns, including disrupted sleep, frequent waking and early waking, that can lead to less sleep time.¹¹

six-month data show significant improvements in patient-reported measures of sleep onset and sleep maintenance for investigational agent lemborexant

tokyo and stamford, conn. – february 4, 2019 – eisai co., ltd. (ceo: haruo naito, “eisai”) and purdue pharma l.p. (president and ceo: craig landau, md, “purdue pharma”) today announced six-month results from sunrise 2, a long-term phase 3 clinical study evaluating the efficacy and safety of lemborexant, an investigational agent being developed for the treatment of insomnia, a sleep-wake disorder. data were presented at the sleep research society’s advances in sleep and circadian science conference, taking place in clearwater beach, florida, feb. 1-4, 2019.

sunrise 2 was a 12-month multicenter, global, randomized, controlled, double-blind, parallel-group study of the efficacy and safety of lemborexant in 949 adult patients (18 to 88 years of age) with insomnia disorder, which was characterized by difficulty falling asleep and/or staying asleep. approximately 28 percent of the patients randomized and treated were 65 years of age or older. during the first six months of the study, patients were randomized to receive either lemborexant 5 mg, lemborexant 10 mg, or placebo. the primary and key secondary efficacy objectives were assessed by patient self-reports via electronic sleep diaries.

at the end of the six-month, placebo-controlled treatment period, treatment with lemborexant at either 5 mg or 10 mg resulted in statistically significant improvements compared to placebo in patient-reported (subjective) sleep onset latency (ssol), the study’s primary efficacy endpoint, and subjective sleep efficiency (sse) and subjective wake after sleep onset (swaso), the study’s key secondary endpoints. six-month results from the study showed that:
● median reductions from baseline in ssol with lemborexant 5 mg (–21.81 minutes) and 10 mg (–28.21 minutes) were larger and statistically significant compared to placebo (–11.43 minutes) at the end of month six (p<0.0001 for all treatment groups).
● improvements from baseline, as measured by least squares mean (lsm), in sse with lemborexant 5 mg (14.19 percent, p=0.0001) and 10 mg (14.31 percent, p<0.0001) were larger and statistically significant compared to placebo (9.64 percent) at the end of month six.
● reductions from baseline in swaso, as measured by lsm, with lemborexant 5 mg (–46.75 minutes, p=0.0005) and 10 mg (–41.95 minutes, p=0.0105) were larger and statistically significant compared with placebo (–29.28 minutes) at the end of month six.

most adverse events (aes) reported were mild to moderate. serious aes were reported at a rate of 2.2 percent (lemborexant 5 mg), and 2.9 percent (lemborexant 10 mg), and 1.6 percent (placebo); only one was considered treatment-related. the most common aes reported, greater than 5 percent in either lemborexant treatment arm and greater than placebo, were somnolence, headache, and influenza. discontinuation rates due to aes were comparable between placebo and lemborexant 5 mg (3.8 percent and 4.1 percent, respectively), and higher for lemborexant 10 mg (8.3 percent).

“these findings add to the growing body of clinical data supporting the development of lemborexant for the treatment of insomnia, and we look forward to presenting 12-month results from the study in a future scientific forum,” said lynn kramer, md, chief clinical officer and chief medical officer, neurology business group, eisai. “it remains our aspiration to bring a medicine to physicians and patients that helps patients sleep well at night and wake well in the morning.”

sunrise 2 is one of two phase 3 safety and efficacy studies of lemborexant conducted by eisai and purdue pharma. these studies supported the new drug application for lemborexant for the treatment of insomnia, filed with the u.s. food and drug administration, on december 27, 2018. in japan, an application is scheduled to be filed within fiscal 2018.

“the six-month findings from sunrise 2 are exciting, highlighting improvements in subjective measures of both sleep onset and sleep maintenance,” said john renger, phd, head of research & development and regulatory affairs, purdue pharma. “sunrise 2 was a robust phase 3 clinical study in which the self-reported patient outcomes are encouraging as they reflect the patients’ perception of lemborexant’s impact on enabling the patient to both fall asleep faster and stay asleep longer.”

lemborexant, which acts on the orexin neurotransmitter system and is believed to regulate sleep and wake by dampening wakefulness without impeding the ability to awaken to external stimuli, is being jointly developed by eisai and purdue pharma for the treatment of multiple sleep-wake disorders, including insomnia disorder. in addition to the treatment of insomnia disorder, a phase 2 clinical study of lemborexant in patients with irregular sleep-wake rhythm disorder and mild to moderate alzheimer’s dementia is underway. information about ongoing clinical studies is available at clinicaltrials.gov.

eisai and purdue pharma are striving to address new unmet medical needs and to improve the lives of patients and their families.

this release discusses investigational uses of an agent in development and is not intended to convey conclusions about efficacy or safety. there is no guarantee that such an investigational agent will successfully complete clinical development or gain health authority approval.
