Phase 1 |
Detailed Description
The drug being tested in this study is called TAK-994. TAK-994 is being tested to find a safe and well-tolerated dose in healthy participants (non-Japanese and Japanese) and healthy elderly participants. The study will enroll up to approximately 160 healthy participants. The study consists of 6 parts and up to 20 cohorts as mentioned below.
-
TAK-994: Part A: Single-rising dose (SRD) design to assess the safety, tolerability, and PK of TAK-994 and effect of food on the PK of the TAK-994
-
TAK-994: Part B: MRD design to assess the safety, tolerability, PK and PD of TAK-994
-
TAK-994: Part C: MRD design to assess the safety, tolerability, PK and PD of TAK-994 and also central nervous system penetration relative to plasma concentrations of TAK-994
-
TAK-994: Part D: MRD design to assess the safety, tolerability, PK and PD of TAK-994 for HE participants
-
TAK-994: Part E: SRD and MRD design to assess the safety, tolerability, PK and PD of TAK-994 for Japanese origin participants
-
TAK-994: Part F (Optional Cohort): Nonrandomized design to assess orexin (OX) levels in the cerebrospinal fluid (CSF) of untreated healthy adult participants.
Participants in each cohort will be randomized to receive treatment with TAK-994 or matching placebo which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need). Participants in optional Part F will receive no study drug.
This multi-center trial will be conducted in the United States. The overall duration of the study is approximately 10 months. Participants will be followed up for 7 days after the last dose of study drug for a follow-up assessment.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: TAK-994: Part A TAK-994 tablet or matching placebo, orally, once on Day 1 to healthy non-Japanese participants. Sentinel dosing will be done in the first 2 cohorts of Part A (Cohorts A1 and A2 [fasted and fed dosing conditions]). Dose escalation in Cohorts A2 to A6 will be based on emerging safety, tolerability, and PK (pharmacokinetic) data from previous cohorts. |

TAK-994 tablets.
Drug: TAK-994 Placebo
TAK-994 placebo-matching tablets.
|
| Experimental: TAK-994: Part B TAK-994 tablet or matching placebo, orally, once daily or twice daily from Day 1 to Day 14 to healthy non-Japanese participants. Dose escalation will be based on review of the emerging safety, PK, and PD (pharmacodynamic) data from Part A. Fixed-dose titration regimens may also be evaluated based on review of the emerging safety, PK, and tolerability data from previous cohorts. |

|
| Experimental: TAK-994: Part C TAK-994 tablet or matching placebo, orally, once daily or twice daily from Day 1 to Day 7 to healthy non-Japanese participants. Dose will be determined based on previous multiple-rising dose (MRD) cohorts. |

|
| Experimental: TAK-994: Part D TAK-994 tablet or matching placebo, orally, once daily or twice daily from Day 1 to Day 14 to healthy non-Japanese elderly participants. Dose will be determined based on previous MRD cohorts. Fixed-dose titration regimens may also be evaluated based on review of the emerging safety, PK, and tolerability data from previous cohorts. |
