E2027E2027Four sequential cohorts of healthy participants (≥50 years and ≤85 years old) will be treated with multiple ascending doses of E2027 up to the maximum tolerated dose (MTD). A total of 6 participants per cohort will be randomized to E2027.Proposed doses of E2027 are: * Part A Cohort 1: 50 mg (1 × 50 mg capsule) * Cohort 2: 100 mg (2 × 50 mg capsules) * Cohort 3: 200 mg (4 × 50 mg capsules) * Cohort 4: 400 mg (8 × 50 mg capsules) * Cohort 6: 25 mg (5 × 5 mg capsules) Part B * Cohort 5: 400 mg (8 × 50 mg capsule) Part C: • Cohort 7: 50 mg (1 × 50 mg capsules) Part D: * Cohort 8: 5 mg (1 × 5 mg capsules) * Cohort 9: 10 mg (2 × 5 mg capsules)
PlaceboE2027 matched placeboFour sequential cohorts of healthy participants (≥50 years and ≤85 years old) will be treated with multiple ascending doses of E2027 matched placebo up to the MTD. A total of 2 participants per cohort will be randomized to E2027 matched placebo.
