Clinical Trial Summary

The purpose of this study is to investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of TAK-925 when administered to healthy participants and narcolepsy participants.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs)	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)
Secondary	Parts A, B and C; Ceoi: Observed Plasma Concentration at the End of Infusion for TAK-925	This assessment was pre-specified to be conducted for participants in "Part A', Cohort A'1: TAK-925 112 mg" as exploratory measures.	Part A,Days 1,7:pre-infusion(inf),0.5,1, 1.5, 2, 4, 6, 8, 9 hours(h)post start of inf;0.17, 0.33, 0.5, 0.75, 1, 1.5, 2, 3, 6, 10, 15 h post end of inf;Part B,C:Days 1,7:Pre-inf, 1, 2, 4, 6, 9 h post start of inf; 0.17, 0.5, 2, 6, 10, 15 h post end of inf
Secondary	Parts A, B and C; AUCtau: Area Under the Plasma Concentration-Time Curve During a Dosing Interval for TAK-925	This assessment was pre-specified to be conducted for participants in "Part A', Cohort A'1: TAK-925 112 mg" as exploratory measures.	Part A,Days 1,7:pre-infusion(inf),0.5,1, 1.5, 2, 4, 6, 8, 9 hours(h)post start of inf;0.17, 0.33, 0.5, 0.75, 1, 1.5, 2, 3, 6, 10, 15 h post end of inf;Part B,C:Days 1,7:Pre-inf, 1, 2, 4, 6, 9 h post start of inf; 0.17, 0.5, 2, 6, 10, 15 h post end of inf
Secondary	Parts A, B and C; Rac (AUC): Accumulation Ratio Based on AUCtau for TAK-925	Accumulation Ratio of AUC was calculated as AUCtau on Day 7 divided by AUCtau on Day 1. This assessment was pre-specified to be conducted for participants in "Part A', Cohort A'1: TAK-925 112 mg" as exploratory measures.	Part A,Days 1,7:pre-infusion(inf),0.5,1, 1.5, 2, 4, 6, 8, 9 hours(h)post start of inf;0.17, 0.33, 0.5, 0.75, 1, 1.5, 2, 3, 6, 10, 15 h post end of inf;Part B,C:Days 1,7:Pre-inf, 1, 2, 4, 6, 9 h post start of inf; 0.17, 0.5, 2, 6, 10, 15 h post end of inf
Secondary	Parts B and C: Change From Baseline in Sleep Latency in the Maintenance of Wakefulness Test (MWT) at Days 1 and 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.	Baseline, Day 1 and Day 7
