About this trial
The purpose of this study is to generate evidence of the safety, tolerability, and pharmacokinetics/pharmacodynamics of IV LY4006896 compared with placebo in healthy participants and participants with Parkinson's disease.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Have a body mass index within the range of 18 to 34 kilogram per square meter (kg/m²) (inclusive).
For Japanese participants: To qualify as a participant of first-generation Japanese origin, the participant, the participant's biological parents, and all of the participant's biological grandparents must be of exclusive Japanese descent and born in Japan.
Have venous access sufficient to allow for blood sampling or administration of study intervention for IV administration, or both.
Participant must be 30 to 85 years of age (inclusive), at the time of signing the informed consent
Disqualifiers
Have significant neurological disease affecting the central nervous system (CNS) (other than Parkinson's disease in Part B cohorts) that may affect the participant's ability to complete the study.
Have a history or presence of serious or unstable illnesses or conditions that, in the investigator's opinion, could interfere with the analyses in this study, or increase risk for study intervention administration, or result in a participant's life expectancy of less than 24 months.
Have known allergies to LY4006896, related compounds, or any components of the formulation, or history of allergic reactions to any transferrin receptor antibodies.
Have significant allergies to humanize monoclonal antibodies.
