Detailed Description
The drug being tested in this study is called TAK-925. TAK-925 is being tested in healthy participants and participants with narcolepsy. This study will look at the safety, tolerability, pharmacokinetics, and efficacy of TAK-925.
This study will consist of three parts. Part A will be a randomized, double-blind, placebo-controlled, multiple rising dose (MRD) study in healthy participants. Part B is a randomized, double-blind, placebo-controlled MRD study in participants with narcolepsy. Part C is a randomized, double-blind, placebo-controlled, parallel group, multiple repeat dose study in participants with narcolepsy. Part A' is a single dose study in healthy participants.
The study will enroll approximately 96 participants planned as total. All participants except Part A' will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which will remain undisclosed to the participants and study doctor during the study (unless there is an urgent medical need):
Part A:
- TAK-925 (Dose Levels A1-A6)
- Placebo
Part B:
- TAK-925 (Dose Levels B1-B4)
- Placebo
Part C:
- TAK-925 (Dose Levels C1-C2)
- Placebo
Part A':
• TAK-925 (Dose Levels A'1-A'2)
All participants will be asked to take TAK-925 or Placebo at the same time each day from Day 1 to Day 7 in Parts A, B and C, and take TAK-925 on Day 1 in Part A'.
This multi-center trial will be conducted in Japan. The overall study period is approximately 15 days in Parts A, B and C, and approximately 7 days for Part A'. Participants will be partly admitted to a hospital during the study.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs)
Time Frame: From the first dose of study drug up to 7 days after the last dose of study drug (up to Day 15)
|
An Adverse Event (AE) was defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment.
An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug.
A TEAE was defined as an AE with an onset that occurs after receiving study drug.
|
From the first dose of study drug up to 7 days after the last dose of study drug (up to Day 15)

Parts B and C: Change From Baseline in Sleep Latency in the Maintenance of Wakefulness Test (MWT) at Days 1 and 7
Time Frame: Baseline, Day 1 and Day 7
|
The MWT is a validated objective measure that is used to measure excessive daytime sleepiness in clinical studies.
It has been used as a secondary outcome measure for excessive daytime sleepiness.
The MWT evaluates a person's ability to remain awake under soporific conditions for a defined period of time.
Wakefulness in this study was measured indirectly by time to fall asleep using MWT.
In this study, four 40-minute (1 session) MWT assessments per day was administered on Baseline, Day 1 and Day 7. MWT sleep latency ranges from 0 to 40 minutes, with longer sleep latency indicating greater ability to stay awake.
