A Long-Term Multicenter, Randomized, Double-Blind, Controlled, Parallel Group Study of the Safety and Efficacy of Lemborexant in Subjects With Insomnia Disorder (SUNRISE 2)

The key objectives of this study are to determine, using sleep diaries, whether lemborexant
at the doses 5 milligrams (mg) and 10 mg is superior to placebo on subjective sleep onset,
subjective sleep efficiency, and subjective sleep maintenance in participants with insomnia
disorder.

This is a long-term (approximately 1 year), multicenter, randomized, controlled,
double-blind, parallel group study of two doses of lemborexant and placebo in approximately
900 male or female participants with insomnia disorder. Approximately 40% of participants
will be age 65 years or older. The study will last a maximum of 60 weeks, and will include a
Screening Period, an approximately 54-week Treatment Period (during which study medication
will be administered), and a 2-week Follow-up Period. All participants will receive
lemborexant for at least 6 months and will receive placebo at some point during the study.
Participants will not know which medication they receive (lemborexant or placebo) until the
study has been completed, and will not know the timings at which the medication will change.

minutes on at least 3 nights per week in the previous 4 weeks

- History of regular time spent in bed, either sleeping or trying to sleep, between 7

- Confirmation of current insomnia symptoms as determined from the Sleep Diary completed

≥30 minutes on at least 3 of the 7 nights and/or sWASO ≥60 minutes on at least 3 of
the 7 nights

- Confirmation of time spent in bed, as determined from on the Sleep Diary completed on
7 mornings between the first and second screening visit, such that there are not more
than 2 nights with duration of time spent in bed 7 hours and 10 hours

regular time spent in bed, either sleeping or trying to sleep, between 7 and 10 hours

complex sleep-related behavior, eg, making phone calls, or preparing and eating food
while asleep

- For participants who underwent polysomnography (PSG) within the previous year:

- Age 18 to 64 years: Apnea Hypopnea Index ≥10, or Periodic Limb Movements with
Arousal Index ≥10

- Age ≥65 years: Apnea Hypopnea Index >15, or Periodic Limb Movements with Arousal
Index >15

- Beck Depression Inventory - II (BDI II) score >19 at Screening

- Beck Anxiety Inventory (BAI) score >15 at Screening

- Habitually naps more than 3 times per week

- Females of childbearing potential who are not practicing acceptable pregnancy
prevention methods (NOTE: All females will be considered to be of childbearing
potential unless they are postmenopausal or have been sterilized surgically.)

- Excessive caffeine use that in the opinion of the investigator contributes to the
participant's insomnia, or habitually consumes caffeine-containing beverages after
18:00 and is unwilling to forego caffeine after 18:00 for the duration of his/her

hours before bedtime for the duration of his/her participation in the study

- A prolonged QT/QT interval corrected by Fridericia's formula (QTcF >450 ms) as
demonstrated by a repeated electro cardiogram(ECG) at Screening (repeated only if
initial ECG indicates a QTcF interval >450 ms)

- Current evidence of clinically significant disease (e.g., cardiac, respiratory,
gastrointestinal, renal, neurological [including participants who lack capacity and/or
whose cognitive decline indicates disorientation to person/place/time and/or
situation], or psychiatric disease or malignancy other than basal cell carcinoma) or
chronic pain that in the opinion of the investigator(s) could affect the participant's
safety or interfere with the study assessments

- Comorbid nocturia resulting in frequent need to get out of bed to use the bathroom
during the night

- Scheduled for major surgery during the study

- Used any prohibited prescription or over-the-counter concomitant medications within 1
week before the first dose of study medication
