New Alzheimer's drug enters human safety trials
NCT ID NCT06657768
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This early-stage study tests a new drug called LY4006895 in healthy volunteers and people with early symptomatic Alzheimer's disease. The main goal is to check if the drug is safe and how the body processes it. The study has two parts: a single dose in healthy people and multiple doses in Alzheimer's patients over several months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

- LY4006895
- What this could lead to
- If this drug is safe and shows promise, it could lead to a new treatment option for early Alzheimer's disease.
- What could go wrong
- This is an early Phase 1 trial focused on safety, not effectiveness. The drug may not work or could have side effects. Results are years away from any potential treatment.
