Brief Summary:
The purpose of this study is to investigate safety, tolerability, and pharmacokinetics of TAK-925 when a single dose of TAK-925 is administered to healthy adult participants, healthy elderly participants and patients with type 1 narcolepsy.

Condition or disease Intervention/treatment Phase
Healthy Participants and Patients With Narcolepsy Drug: TAK-925 Drug: Placebo Phase 1

Detailed Description:

Orexins are neuropeptides that play a role in the regulation of sleep and wakefulness. In type 1 narcolepsy, there is a loss of orexin producing neurons in the brain. The investigational drug, TAK-925, is an orexin 2 receptor agonist that is being tested in healthy adult participants, healthy elderly participants and patients with narcolepsy in order to evaluate the safety, tolerability, and pharmacokinetics (PK) of a single intravenous administration.

The study will enroll approximately 20 healthy participants and 16 healthy elderly participants in Part 1 of the study and approximately 20 patients with narcolepsy in Part 2.

In Part 1, the study consists of 4 cohorts of 8 or 4 participants each. Participants will be randomly assigned (by chance, like flipping a coin) to one of the following treatment groups to receive TAK-925 or placebo:

- Part 1, Cohort 1; TAK-925 (Dose Level 1, 3, 5), Cohort 2; TAK-925 (Dose Level 2, 4, 6), Cohort 3 and 4; TAK-925 (Dose Level 5)

For Cohort 1-4, healthy adult and elderly participants will be administered TAK-925 or placebo once in each cohort or dose level. The dose at the start (Cohort 1 dose level 1) is 7 mg of TAK-925 and following doses in Cohorts 1-4 will be determined based on available data from previous Cohorts/dose levels.

In Part 2 of the study, the study consists of 3 cohorts of 4 to 12 patients with narcolepsy. Patients will be randomly assigned to one of the treatment groups of Cohort 5-7 and will be administered TAK-925 or placebo once in each cohort. The dose of TAK-925 in Cohort 5-7 is TBD and will be decided based on available data from Part 1 and previous Cohorts.

- Part 2, Cohort 5-7

This multi-center trial will be conducted in Japan. Participants will make multiple visits to the clinic. Visits in Part 1 will include a screening period (Day -28 to -2), Check-in on Day -1, Treatment period (Day 1 and 2), and follow-up visit on Day 7. In Part 2 of the study, the visits include a screening period (Day -42 to -2), Check-in on Day -1, Cross-over period (Day 1 to 4), and follow-up visit on Day 7.

Secondary Outcome Measures :
  1. Part 2: Average Sleep Latency in Maintenance of Wakefulness Test (MWT) [ Time Frame: Days 1 and 3 up to 8 hours following the start 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. 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.
