The purpose of this study is to assess the safety, tolerability and pharmacokinetics of TAK-137 in healthy male subjects.
This study is a phase 1, randomized, placebo-controlled, double-blind, multiple ascending dose study in Japanese healthy male participants to assess the safety, tolerability and PK following single and multiple oral doses of TAK-137.
This study is composed of 2 parts, a Single Dose part (Cohorts 1 to 3) and a Multiple Dose part (Cohorts 4 to 6). Up to 48 participants will be enrolled.
Single dose part (Cohorts 1-3): Single Dose, 3 dose levels, Placebo-Controlled, Randomized, Double-Blind.
Each cohort will include 8 participants. Participants will be randomly assigned to either TAK-137 or placebo treatment group within each cohort with an allocation ratio of 6:2.
The planned dose levels to be studied are 5, 10 and 20 mg. The principal investigator will consult with the sponsor and the medical specialist as needed and will determine go/no-go for the next cohort.. The dose in Cohorts 3 may be reduced to 2 mg/day instead of 20 mg/day if the principal investigator, in consultation with the sponsor, considers it appropriate.
Multiple dose Part (Cohorts 4-6): Multiple Dose, 3 dose levels, Placebo-Controlled, Randomized, Double-Blind.
Each cohort will include 8 participants. Participants will be randomly assigned to either TAK-137 or placebo treatment group within each cohort with an allocation ratio of 6:2.
The planned dose levels to be studied are 5, 10,and 15 mg, however for Cohort 5 and 6, the dose level may be amended based on the safety and tolerability data obtained from either Cohorts 1-4 from this study or emerging data from the multiple rising dose study conducted, in parallel in the United Sates (TAK-137_102). The principle investigator, in consultation with the sponsor, will determine the dose levels for cohorts 5 and 6 (Not exceeding 20mg).

| Frequencies of Adverse events (Single dose Part) | The frequencies of all adverse events observed during the observation period will be tabulated by type and seriousness, and causal relationship to TAK-137. Adverse events are defined as any unfavorable and unintended signs, symptoms or diseases temporally associated with the use of a medicinal product, reported from the first dose to the last dose of TAK-137. | Up to 8 days |
| Frequencies of Adverse events (Multiple dose Part) | The frequencies of all adverse events observed during the observation period will be tabulated by type and seriousness, and causal relationship to TAK-137. Adverse events are defined as any unfavorable and unintended signs, symptoms or diseases temporally associated with the use of a medicinal product, reported from the first dose to the last dose of TAK-137. | Up to 14 days |
| Descriptive statistics (mean, SD, median, minimum and maximum) of changes from baseline for vital sign measurements at least once post-dose (Single dose Part) | Up to 8 days | |
| Descriptive statistics (mean, SD, median, minimum and maximum) of changes from baseline for vital sign measurements at least once post-dose (Multiple dose Part) | Up to 9 days | |
| Descriptive statistics (mean, SD, median, minimum and maximum) of changes from baseline for body weight measurements at least once post-dose (Single dose Part) | Up to 8 days | |
| Descriptive statistics (mean, SD, median, minimum and maximum) of changes from baseline for body weight measurements at least once post-dose (Multiple dose Part) | Up to 9 days | |
