Eisai to Present Latest Insomnia Research, Including Data on New Treatment DAYVIGO(TM) (lemborexant) CIV, at the SLEEP 2020 Virtual Conference
WOODCLIFF LAKE, N.J., Aug. 24, 2020 /PRNewswire/ -- Eisai Inc., the U.S. pharmaceutical subsidiary of Eisai Co., Ltd., today announced it will present new DAYVIGO(TM) (lemborexant) CIV research at the SLEEP 2020 virtual conference, the 34th annual meeting of the Associated Professional Sleep Societies, August 27-30, 2020. DAYVIGO, a dual orexin receptor antagonist, was recently launched in the U.S. for the treatment of adults with insomnia characterized by difficulties with sleep onset and/or sleep maintenance.(1)
Highlights include an oral presentation focusing on the long-term efficacy and safety of DAYVIGO in adults ages 65 and older with insomnia disorder from the Phase 3 clinical study, SUNRISE 2, in which patients were evaluated for up to 12 months. Additional research to be presented will explore sleep onset and sleep maintenance responder profiles over 12 months of treatment with DAYVIGO, efficacy and safety of DAYVIGO in females of perimenopausal age with insomnia disorder, and impact of DAYVIGO treatment on fatigue severity. In addition, interim results from a multi-center pilot study evaluating the next-dose transition from zolpidem to DAYVIGO for the treatment of insomnia will be presented.
"We look forward to sharing new findings about safety and efficacy of DAYVIGO in specific patient populations, particularly those related to its long-term impact in individuals 65 years and older, at SLEEP 2020," said Lynn Kramer, MD, Chief Clinical Officer, Neurology Business Group, Eisai. "These findings will provide key considerations for addressing insomnia in specific patient populations. Insomnia affects millions of people in the United States.(2) This research is especially relevant now, as we know life changes due to the COVID-19 pandemic are causing increased sleep problems."(3)
Eisai's research to be presented at SLEEP 2020 includes:

[Notes to editors]
1. About Lemborexant
Lemborexant is a 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.(2) In individuals with insomnia, it is possible that orexin signaling regulating wakefulness is not functioning normally.
INDICATION
DAYVIGO (lemborexant) is an orexin receptor antagonist indicated for the treatment of adult patients with insomnia, characterized by difficulties with sleep onset and/or sleep maintenance.
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS
-- DAYVIGO is contraindicated in patients with narcolepsy.
WARNINGS AND PRECAUTIONS
-- Central Nervous System (CNS) Depressant Effects and Daytime Impairment:
DAYVIGO can impair daytime wakefulness. CNS depressant effects may
persist in some patients up to several days after discontinuing DAYVIGO.
Prescribers should advise patients about the potential for next-day
somnolence.Driving ability was impaired in some subjects taking DAYVIGO
10 mg. Risk of daytime impairment is increased if DAYVIGO is taken with
less than a full night of sleep remaining or at a higher than
recommended dose. If taken in these circumstances, patients should not
drive or engage in activities requiring mental alertness. Use with other
classes of CNS depressants (e.g., benzodiazepines, opioids, tricyclic
antidepressants, alcohol) increases the risk of CNS depression, which
can cause daytime impairment. Dosage adjustments of DAYVIGO and
concomitant CNS depressants may be necessary when administered together.
Use of DAYVIGO with other insomnia drugs is not recommended. Patients
should be advised not to consume alcohol in combination with
DAYVIGO.Because DAYVIGO can cause drowsiness, patients, particularly the
elderly, are at a higher risk of falls.
-- Sleep Paralysis, Hypnagogic/Hypnopompic Hallucinations, and
Cataplexy-Like Symptoms: Sleep paralysis, an inability to move or speak
for up to several minutes during sleep-wake transitions,
hypnagogic/hypnopompic hallucinations, including vivid and disturbing
perceptions can occur with DAYVIGO. Prescribers should explain these
events to patients.Symptoms similar to mild cataplexy can occur with
DAYVIGO and can include periods of leg weakness lasting from seconds to
a few minutes, can occur either at night or during the day, and may not
be associated with identified triggering event (e.g., laughter or
surprise).
-- Complex Sleep Behaviors:Complex sleep behaviors, including
sleep-walking, sleep-driving, and engaging in other activities while not
fully awake (e.g., preparing and eating food, making phone calls, having
sex), have been reported to occur with the use of hypnotics such as
DAYVIGO. Events can occur in hypnotic-naïve and hypnotic-experienced
persons. Patients usually do not remember these events. Complex sleep
behaviors may occur following the first or any subsequent use of
DAYVIGO, with or without the concomitant use of alcohol and other CNS
depressants. Discontinue DAYVIGO immediately if a patient experiences a
complex sleep behavior.
-- Patients with Compromised Respiratory Function: The effect of DAYVIGO on
respiratory function should be considered for patients with compromised
respiratory function. DAYVIGO has not been studied in patients with
moderate to severe obstructive sleep apnea (OSA) or chronic obstructive
pulmonary disease (COPD).
-- Worsening of Depression/Suicidal Ideation:Incidence of suicidal ideation
or suicidal behavior, as assessed by questionnaire, was higher in
patients receiving DAYVIGO than placebo (0.3% for DAYVIGO 10 mg, 0.4%
for DAYVIGO 5 mg, and 0.2% for placebo). In primarily depressed patients
treated with hypnotics, worsening of depression and suicidal thoughts
and actions (including completed suicides) have been reported. Suicidal
tendencies may be present in such patients and protective measures may
be required. Intentional overdose is more common in this group of
patients; therefore, the lowest number of tablets that is feasible
should be prescribed at any one time. The emergence of any new
behavioral sign or symptom of concern requires careful and immediate
evaluation.
-- Need to Evaluate for Comorbid Diagnoses: Treatment of insomnia should be
initiated only after careful evaluation of the patient. Reevaluate for
comorbid conditions if insomnia persists or worsens after 7 to 10 days
of treatment. Worsening of insomnia or the emergence of new cognitive or
behavioral abnormalities may be the result of an unrecognized underlying
psychiatric or medical disorder and can emerge during the course of
treatment with sleep-promoting drugs such as DAYVIGO.
ADVERSE REACTIONS
-- The most common adverse reaction (reported in 5% of patients treated
with DAYVIGO and at least twice the rate of placebo) with DAYVIGO was
somnolence (10% for DAYVIGO 10 mg, 7% for DAYVIGO 5 mg, 1% for placebo).
DRUG INTERACTIONS
-- CYP3A Inhibitors: The maximum recommended dose of DAYVIGO is 5 mg no
more than once per night when co-administered with weak CYP3A
inhibitors. Avoid concomitant use of DAYVIGO with strong or moderate
CYP3A inhibitors.
-- CYP3A Inducers: Avoid concomitant use of DAYVIGO with moderate or strong
CYP3A inducers.
USE IN SPECIFIC POPULATIONS
-- Pregnancy and Lactation: There is a pregnancy exposure registry that
monitors pregnancy outcomes in women who are exposed to DAYVIGO during
pregnancy. Healthcare providers are encouraged to register patients in
the DAYVIGO pregnancy registry by calling 1-888-274-2378. There are no
available data on DAYVIGO use in pregnant women to evaluate for a
drug-associated risk of major birth defects, miscarriage, or adverse
maternal or fetal outcomes. There are no data on the presence of
lemborexant in human milk, the effects on the breastfed infant, or the
effects on milk production. Infants exposed to DAYVIGO through
breastmilk should be monitored for excess sedation.
-- Geriatric Use: Exercise caution when using doses higher than 5 mg in
patients >=65 years old.
-- Renal Impairment: Patients with severe renal impairment may experience
an increased risk of somnolence.
-- Hepatic Impairment: The maximum recommended dose of DAYVIGO is 5 mg in
patients with moderate hepatic impairment. DAYVIGO is not recommended in
patients with severe hepatic impairment. Patients with mild hepatic
impairment may experience an increased risk of somnolence.
DRUG ABUSE AND DEPENDENCE
-- DAYVIGO is a Schedule IV-controlled substance.
-- Because individuals with a history of abuse or addiction to alcohol or
other drugs may be at increased risk for abuse and addiction to DAYVIGO,
follow such patients carefully.

2. About Insomnia
Population studies show that sleep disorders affect many more people worldwide than previously thought.(2) Insomnia symptoms affect approximately 30% of the adult population worldwide.(4) Insomnia disorder is characterized by difficulty falling asleep, staying asleep or both, despite an adequate opportunity to sleep.(5 )
Diagnostic criteria for insomnia disorder include if the sleep disturbance causes clinically significant distress or impairment in social, occupational, educational, academic, behavioral or other important areas of functioning, occurs at least three night per week and is present for at least three months.(6)
Sleeping well is essential for good health. Studies suggest an optimal sleep duration between seven and eight hours.(7)
Women are 1.4 times more likely than men to suffer from insomnia.(8) Older adults also have a 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.(9)
3. About SUNRISE 2 (Study 1)(1
)SUNRISE 2: six-month placebo-controlled treatment trial with a 6-month parallel-group extension period including adult patients age 18 or older who met DSM-5 criteria for insomnia disorder. Patients were randomized to placebo (n=325), DAYVIGO 5 mg (n=323), or DAYVIGO 10 mg (n=323) once nightly. The primary efficacy endpoint was the mean change from baseline to end of treatment at six months for subjective sleep onset latency (sSOL; the estimated minutes from the time that the patient attempted to sleep until sleep onset). Secondary efficacy endpoints were mean change from baseline to end of treatment at six months subjective sleep efficiency (sSEF; the proportion of time spent asleep per time in bed) and wake after sleep onset (sWASO; the minutes of wake from the onset of sleep until wake time). These endpoints were measured by sleep diary.
