Testing LY4405094 in healthy people and people with Alzheimer’s disease
Official title: A Placebo-Controlled, Single- and Multiple-Ascending Dose, Phase 1 Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of LY4405094 in Healthy Participants and Participants With Alzheimer's Disease
Run by Eli Lilly and Company · NCT07787182 · Data updated 2026-11-12
This study tests LY4405094 to see if it is safe and how it behaves in the body, including how it reaches the brain fluid in healthy participants and how it affects a brain protein in people with Alzheimer's disease.

Is this trial a fit for you?
✓Likely a good fit
Adults without contraindicating allergies to LY4405094 or formulation components, plus eligibility per the ATMP screening protocol; includes both healthy volunteers and individuals diagnosed with Alzheimer’s disease.
✕Probably not a fit
Some participants may not experience direct clinical benefit from the study or may not meet biomarker or safety thresholds required for dosing.

What this trial studies
This is a Phase 1 interventional study evaluating LY4405094 in both healthy volunteers and individuals with Alzheimer's disease. It aims to characterize safety, absorption, distribution, and pharmacokinetics, including brain fluid exposure in healthy participants and biomarker brain protein levels in Alzheimer’s patients. The study involves a short CRU stay for healthy participants and a longer stay for those with Alzheimer's disease, with placebo-controlled elements and an amyloid imaging agent used as part of the protocol. Duration ranges up to 25 weeks depending on cohort, with multiple study arms including LY4405094 and placebo. Lead sponsor is Eli Lilly and Company, with study sites in California.
Why it matters
Potential benefit: Participants may gain closer monitoring and contribute to knowledge that could lead to future treatments for Alzheimer’s disease.
How similar studies have gone: Prior early-phase studies in similar biologics have informed safety and pharmacokinetics, but this specific LY4405094 approach is relatively novel in Alzheimer’s disease.
