What is the purpose of this trial?

In this study, researchers will learn more about a study drug called BIIB080. BIIB080 is currently a drug under investigation for treatment of Alzheimer's disease. The main question researchers are trying to answer in this study is how radiolabeled BIIB080 distributes in the brain and spinal cord. To help answer this question, researchers will use positron emission tomography (PET) scanner that can detect radiolabeled BIIB080 after a single injection of a small dose of radiolabeled BIIB080 (\[89Zr\]Zr-DFO-BIIB080) and a dose of BIIB080 together via an intrathecal (IT) injection in healthy volunteers. Researchers will also learn about the safety of injecting radiolabeled BIIB080 and BIIB080 together.

Are You a Good Fit for This Trial?

This trial is for healthy adults with a BMI of 18-30 kg/m^2. Men must use effective contraception, and women cannot be able to bear children. It's designed to understand how a potential Alzheimer's drug behaves in the body.

Inclusion Criteria

I am a healthy adult with a BMI between 18 and 30.

I am using a highly effective method of birth control.

I cannot become pregnant.

Exclusion Criteria

My MRI does not show any conditions that could risk my safety in the study.

I have a health condition affecting my heart, hormones, blood, liver, immune system, metabolism, urinary system, lungs, nerves, skin, mental health, kidneys, or I have cancer.

Severe allergic or anaphylactic reactions/systemic hypersensitivity to BIIB080 or any component of the study treatment

What Are the Treatments Tested in This Trial?

Interventions

• BIIB080

Trial Overview Researchers are testing BIIB080, an experimental Alzheimer's drug, by tracking its distribution in the brain and spinal cord using PET scans after injecting it alongside a radiolabeled version called [89Zr]Zr-DFO-BIIB080.

How Is the Trial Designed?

Group I: [89Zr]Zr-DFO-BIIB080 + BIIB080 Experimental Treatment 2 Interventions

Participants will receive a single injection of a small dose of radiolabeled BIIB080 (\[89Zr\]Zr-DFO-BIIB080) along with a dose of BIIB080 together via an intrathecal (IT) injection.
