E2082

Experimental group

Description:

E2082 will be administered as a solution (0.2 milligram \[mg\]), a 0.5 mg tablet, and a 5 mg tablet. Part A: Cohort 1 participants will receive a single dose of a 0.2 mg E2082 solution, and participants in Cohorts 2 to 4, respectively, will receive a single dose of 0.5 mg, 1 mg, or 2.5 mg E2082 tablets under fasted conditions. Cohort 5 participants will receive a single dose of 5 mg E2082 under fasted conditions, and then they will receive 5 mg E2082 under fed conditions after washout. Participants in Cohorts 6 to 10, respectively, will receive 10 mg (adult participants), 15 mg, 25 mg, 40 mg, or 10 mg (elderly participants) E2082 tablets under fasted conditions. Part B: Participants in Cohorts 1 to 4, respectively, will receive 2.5 mg, 5 mg, 10, or 15 mg tablets once daily for 10 days. E2082 will be administered under fasted conditions on Day 1 and Day 10 and under fed conditions during Day 2 to Day 9.

Treatment:

Drug: E2082

E2082-matched placebo

Placebo Comparator group

Description:

Matched placebo will be administered as a solution (0.2 mg), a 0.5 mg tablet, and a 5 mg tablet. Part A: Cohort 1 participants will receive a single dose of a 0.2 mg matched placebo solution, and participants in Cohorts 2 to 4, respectively, will receive a single dose of 0.5 mg, 1 mg, or 2.5 mg matched placebo tablets under fasted conditions. Cohort 5 participants will receive a single dose of 5 mg matched placebo under fasted conditions, and then they will receive 5 mg matched placebo under fed conditions after washout. Participants in Cohorts 6 to 10, respectively, will receive 10 mg (adult participants), 15 mg, 25 mg, 40 mg, or 10 mg (elderly participants) matched placebo tablets under fasted conditions. Part B: Participants in Cohorts 1 to 4, respectively, will receive 2.5 mg, 5 mg, 10, or 15 mg matched placebo tablets once daily for 10 days. Matched placebo will be administered under fasted conditions on Day 1 and Day 10 and under fed conditions during Day 2 to Day 9.
