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.

Condition or disease	Intervention/treatment	Phase
Healthy Volunteers	Drug: TAK-925; Drug: TAK-925 Placebo; Drug: Modafinil; Drug: Modafinil Placebo	Phase 1

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.

Outcome Measures

Go to 

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :

1. Latency in MWT [ Time Frame: Day 1 ]
   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 are 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.

Secondary Outcome Measures :

1. AUClast: Area under the Plasma Concentration-time Curve from Time 0 to the Time of the Last Quantifiable Concentration for TAK-925 and its Metabolites M-I and M-II [ Time Frame: Day 1 pre-dose and at multiple time points (up to 9 hours) post-dose ]
2. AUC∞: Area under the Plasma Concentration-time Curve from Time 0 to Infinity for TAK-925 and its Metabolites M-I and M-II [ Time Frame: Day 1 pre-dose and at multiple time points (up to 9 hours) post-dose ]
3. Cmax: Maximum Observed Plasma Concentration for TAK-925 and its Metabolites M-I and M-II [ Time Frame: Day 1 pre-dose and at multiple time points (up to 9 hours) post-dose ]
4. Ceoi: Plasma Concentration Observed at the end of Infusion for TAK-925 and its Metabolites M-I and M-II [ Time Frame: Day 1 pre-dose and at multiple time points (up to 9 hours) post-dose ]
5. Tmax: Time to Reach the Maximum Plasma Concentration (Cmax) for TAK-925 and its Metabolites M-I and M-II [ Time Frame: Day 1 pre-dose and at multiple time points (up to 9 hours) post-dose ]
6. T1/2z: Terminal Disposition Phase Half-life for TAK-925 and its Metabolites M-I and M-II [ Time Frame: Day 1 pre-dose and at multiple time points (up to 9 hours) post-dose ]
7. CL: Total Clearance after Intravenous Administration for TAK-925 [ Time Frame: Day 1 pre-dose and at multiple time points (up to 9 hours) post-dose ]
8. Vz: Volume of Distribution during the Terminal Disposition Phase after Intravenous Administration for TAK-925 [ Time Frame: Day 1 pre-dose and at multiple time points (up to 9 hours) post-dose ]
9. Vss: Volume of Distribution at Steady State after Intravenous Administration for TAK-925 and its Metabolites M-I and M-II [ Time Frame: Day 1 pre-dose and at multiple time points (up to 9 hours) post-dose ]
10. Sleepiness on the Karolinska Sleepiness Scale (KSS) [ Time Frame: Day 1 ]
    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 better results.
