A Study of LY2624803 in Japanese Participants With Transient Insomnia
December 22, 2015 updated by: Eli Lilly and Company
Pharmacodynamics and Pharmacokinetics of Single Doses of LY2624803 in a 5-hour Phase Advance Model of Transient Insomnia in Healthy Japanese Subjects
The aim of this study is to learn how different doses of LY2624803 affect sleep in healthy Japanese participants.
The study has four treatment periods.
Participants will receive a single dose of LY2624803 or placebo in each treatment period.

- Have an irregular or altered sleep/wake schedule that is likely to prevent from keeping a regular sleep/wake schedule during the study
- Regular napping (≥ 2 daytime naps/week by history)
- Extreme morning type or evening type
- Rhinitis, conjunctivitis, urticaria or chronic pain severe enough to interfere with sleep

- Symptoms consistent with a sleep disorder or history of same
- Evidence of significant active neuropsychiatric disease and in particular evidence of significant medical or psychiatric illness within the past 12 months that could contribute to insomnia
- History or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, neurocardiogenic or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; of constituting a risk when taking the study medication; or of interfering with the interpretation of data
- History or presence of orthostatic signs and symptoms within 2 years
- History of seizure or a close relative having a seizure disorder (such as epilepsy). History of a single febrile convulsion more than 10 years ago is acceptable. History of cranial trauma and loss of consciousness will be discussed prior to including any such participant
- Abnormal movements observed outside of normal sleep time
- Abnormal supine blood pressure and/or pulse rate
- Participants with orthostatic hypotension at screening
- An abnormality in the 12-lead electrocardiogram (ECG) that increases the risks associated with participating in the study

- Use or intended use of prescription (except oral contraceptives), over-the-counter or herbal medication, specifically antihistamines, anticholinergic medications or any medications that affect sleepiness, within 28 days prior to Period 1 dosing and/or during the study
- Participants who have donated more than 200 milliliters (mL) of blood or component blood within one month of screening, or those who have donated more than 400 mL of blood within 3 months of screening
- History of smoking within the previous 6 months of screening
- Participants who have an average weekly alcohol intake that exceeds 21 units per week (males) and 14 units per week (females), or participants unwilling to stop alcohol consumption for the period
- Participants whose daily caffeine intake does not permit maintenance of usual sleep/wake schedule
- No response to phase advance or a placebo responder
- Sleep disorders detected during the PSG screening night
- History or presence of breast cancer

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Wake After Sleep Onset (WASO) With LY2624803 Compared to Placebo
Time Frame: 8 hours in Periods 1, 2 and 3
|
WASO was calculated as total time in awake epochs between sleep onset time (first stage 2 epoch) and the end of the primary recording period (8 hours after lights -off).
Data presented are Geometric Least Squares (LS) means.
Geometric LS mean was calculated using mixed models analysis.
The model included factors for treatment, treatment sequence, period and participants.

LPS is defined as the latency from the lights-off time to the first stage 2 sleep followed by at least 10 consecutive minutes of sleep epochs.
Data presented are Geometric LS means.
Geometric LS mean was calculated using mixed models analysis.
