This study is exploring a new treatment, ADEL-Y01, for Alzheimer's disease (AD). AD is a brain illness causing memory loss. The study has two parts: Part 1 tests a single dose in healthy adults aged 18-65; Part 2 tests multiple doses in people aged 50-80 with mild memory problems due to AD. ADEL-Y01 is a special type of medicine called a monoclonal antibody, which helps clear bad proteins in the brain. The study checks how safe ADEL-Y01 is, how the body processes it, and its effects on the brain. Participants must be healthy, meet specific health criteria, and agree to the study rules.
- Commitment: Up to 12 weeks for Part 1; up to 22 weeks for Part 2.
- Visits: Frequent visits to a research center for check-ups and medicine doses.
- Risks: Possible side effects being studied, including safety and tolerability.
