About

The purpose of this study is to investigate the safety of a single dose of Lu AF87908, how well it is tolerated and what the body does to the drug in healthy participants and participants with Alzheimer's disease.

Full description

The study will be divided into three parts: Part A, Part B and Part C. Part A consists of up to 6 sequential cohorts (Cohorts A1 to A6): -Cohorts A1 to A6: 8 healthy participants per cohort (aiming for an equal number of men and women): 6 randomized to Lu AF87908 and 2 randomized to placebo. Part B consists of up to 3 sequential cohorts (Cohorts B1 to B3): -Cohorts B1 to B3: 4 Japanese and 4 Chinese healthy participants per cohort: 6 participants randomized to Lu AF87908 and 2 participants randomized to placebo. Part C consists of 2 sequential cohorts (Cohorts C1 and C4): -Cohort C1 will consist of 6 participants with Alzheimer's disease with 3:1 randomization scheme for active: placebo. Cohort C4 will consist of up to 8 participants. Cohort C4 participants will be randomized based on the randomization scheme from Cohort C1.
