Brief summary

The purpose of this study is to determine the effect of TAK-925 after a single intravenous dose (compared to placebo) on promoting wakefulness as measured by sleep latency on the maintenance of wakefulness (MWT) in sleep-deprived healthy participants.

Detailed description

The drug being tested in this study is called TAK-925. This study will assess the safety, tolerability, PK and PD of TAK-925 and will assess the effects of TAK-925 in sleep-deprived healthy adult participants. The study will enroll approximately 20 participants. Participants will be randomly assigned (by chance, like flipping a coin) to one of the 4 treatment sequences-which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need): * TAK-925 Low Dose + Placebo + TAK-925 High Dose + Modafinil * TAK-925 High Dose + TAK-925 Low Dose + Modafinil + Placebo * Modafinil+ TAK-925 High Dose + Placebo + TAK-925 Low Dose * Placebo + Modafinil + TAK-925 Low Dose + TAK-925 High Dose TAK-925 will be administered as an intravenous infusion based on the availability of safety, tolerability and PK data from health Japanese participants in ongoing study TAK-925-1001. This single center trial will be conducted in the United States. The overall time to participate in this study is approximately 10 weeks. Participants will make a final visit 7 days after receiving their last dose of drug for a follow-up assessment.

Inclusion criteria

1. Be a nonsmoker who has not used tobacco- or nicotine-containing products (example, nicotine patch) for at least 6 months before study drug administration of the initial dose of study drug. 2. Have regular sleep-wake habits (example, routinely spending 6.5 to 8 hours sleeping nightly, not oversleeping by more than 3 hours on weekends, that is, total sleep not more than 11 hours) as determined by investigator interviews and confirmed in 5-day actigraphy records and whom regularly fall asleep between 9:30 PM and 12:00 AM. 3. Be willing to have actigraphy monitoring during the week before randomization and in each interval.

Exclusion criteria

1. Has a positive alcohol or drug screen. 2. Has a history of alcohol consumption exceeding 2 standard drinks per day on average (1 glass is approximately equivalent to: beer \[354 milliliter per (mL/)12 ounces\], wine (118 mL/4 ounces), or distilled spirits (29.5 mL/1 ounce)\] per day). 3. Has excessive sleepiness defined by a self-reported Epworth Sleepiness Scale score at screening greater than 10; irregular work hours; or routine night-shift work within 1 month before randomization. 4. Currently experiencing or having a history of any known/suspected sleep disorder, any disorder associated with excessive daytime somnolence (EDS), or any diagnosis interfering with assessment of sleepiness. 5. Abnormal findings on the initial polysomnography (PSG) conducted on Day -1 (check-in), as specified in the study manual. 6. Traveled across 2 or more time zones 2 weeks or less before screening. 7. Caffeine consumption of more than 400 milligram per day (mg/day) for 2 weeks before screening (1 serving of coffee is approximately equivalent to 120 mg of caffeine).

Latency to Sleep Onset on Maintenance of Wakefulness Test (MWT) at 2 Hours Post-infusion StartDay 1: 2 hours post-infusion startThe MWT is a validated objective measure that evaluates a person's ability to remain awake under soporific conditions for a defined period of time. This tendency to fall asleep is measured via electroencephalography-derived sleep latency. Sleep onset is defined as the first epoch of greater than 15 seconds of cumulative sleep in a 30-second epoch. Trials were ended after 40 minutes if no sleep occurs, or after unequivocal sleep, defined as 3 consecutive epochs of stage 1 sleep, or 1 epoch of any other stage of sleep. If no sleep has been observed according to these rules, then the latency is defined as 40 minutes. MWT sleep latency ranges from 0 to 40 minutes, with higher scores indicating greater ability to stay awake.

This tendency to fall asleep is measured via electroencephalography-derived sleep latency. Sleep onset is defined as the first epoch of greater than 15 seconds of cumulative sleep in a 30-second epoch. Trials were ended after 40 minutes if no sleep occurs, or after unequivocal sleep, defined as 3 consecutive epochs of stage 1 sleep, or 1 epoch of any other stage of sleep. If no sleep has been observed according to these rules, then the latency is defined as 40 minutes. MWT sleep latency ranges from 0 to 40 minutes, with higher scores indicating greater ability to stay awake.

Sleepiness on KSS

The KSS scale measures the subjective level of sleepiness at a particular time during the day. On this scale participants indicate which level best reflects the psycho-physical state experienced in the last 10 minutes. The KSS is a 9-item Likert-type rating scale for assessing subjective sleepiness, where 1=very alert, 3=alert, 5=neither alert nor sleepy, 7=sleepy (but not fighting sleep), 9=very sleepy (fighting sleep). Lower score indicates more alertness.

Time frame: Day 1: 14, 10, 6, 2 hours pre-infusion; 2.75, 4.75, 6.75. 8.75 hours post-infusion start; 1.75 hours post-infusion end

Population: The PD analysis set consisted of all participants who received at least 1 dose of study drug and have at least 1 evaluable postdose PD endpoint derived from the MWT, PSG, KSS, or CCBT. The PD analysis set where data at specified time points was available.
