A Study of LY4405094 in Healthy Participants and Participants With Alzheimer's Disease
A Phase 1 study testing LY4405094, Florbetapir F18 and Florbetaben F 18 in people with Healthy Volunteers and Alzheimer Disease, run by Eli Lilly and Company at 18 sites in 3 countries.
Trial summary
The purpose of this study is to see how safe LY4405094 is and to see how much and how quickly LY4405094 gets into the bloodstream. For healthy participants, the study also looks at how much LY4405094 gets into the fluid around the brain and lasts up to 13 weeks and will include a 4-day stay in the Clinical Research… Read more about this study

About this study
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
The purpose of this study is to see how safe LY4405094 is and to see how much and how quickly LY4405094 gets into the bloodstream. For healthy participants, the study also looks at how much LY4405094 gets into the fluid around the brain and lasts up to 13 weeks and will include a 4-day stay in the Clinical Research Unit (CRU). For participants with Alzheimer's Disease, the study will also look at levels of a specific Alzheimer's-related protein in the brain and will last up to 25 weeks and will include a 3-day stay in the CRU.

| Study group | Role | What they receive |
|---|---|---|
| LY4405094 Part A: Single-Ascending Dose (SAD) | Experimental | LY4405094 administered intravenously (IV) or subcutaneously (SC) in healthy volunteers. Receives: Drug: LY4405094 |

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants with One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration
Measured: Baseline up to 25 Weeks
Secondary outcomes (4)
Pharmacokinetics (PK): Maximum Concentration (Cmax) of LY4405094 in Healthy Participants
Measured: Baseline through Study Completion (Week 13)
PK: Area Under the Concentration Versus Time Curve (AUC) of LY4405094 in Participants with Alzheimer's Disease (AD)
Measured: Baseline through Study Completion (25 Weeks)
Change from Baseline of Cerebrospinal Fluid (CSF) Concentration of LY4405094 in Healthy Participants
Measured: Baseline through Study Completion (Week 13)
Change from Baseline of Amyloid Plaque levels as Assessed by Amyloid Positron Emission Tomography (PET) in Participants with AD
Measured: Baseline through Study Completion (25 Weeks)
