Healthy Volunteers | Drug: TAK-925 Drug: TAK-925 Placebo Drug: Modafinil Drug: Modafinil Placebo | Phase 1 |
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.

- Latency to Sleep Onset on Maintenance of Wakefulness Test (MWT) at 2 Hours Post-infusion Start [ Time Frame: Day 1: 2 hours post-infusion start ]The 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.
- Latency to Sleep Onset on MWT at 4 Hours Post-infusion Start [ Time Frame: Day 1: 4 hours post-infusion start ]The 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.
- Latency to Sleep Onset on MWT at 6 Hours Post-infusion Start [ Time Frame: Day 1: 6 hours post-infusion start ]The 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.
- Latency to Sleep Onset on MWT at 8 Hours Post-infusion Start [ Time Frame: Day 1: 8 hours post-infusion start ]The MWT is a validated objective measure that evaluates a person's ability to remain awake under soporific conditions for a defined period of time.

MWT sleep latency ranges from 0 to 40 minutes, with higher scores indicating greater ability to stay awake.
- Latency to Sleep Onset on MWT at 1 Hour Post-end of Infusion [ Time Frame: Day 1: 1 hour post-end of infusion ]The 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.

- Sleepiness on KSS [ 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 ]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.
