A Crossover Study to Evaluate Pegilodecakin (LY3500518) in Healthy Participants (Willow 3)

July 10, 2026 updated by: Eli Lilly and Company

An Open Label, Randomized, Single Dose, 2-Way Crossover Study to Evaluate the Pharmacokinetics of Pre-filled Syringe Versus Vial Formulations of AM0010 in Healthy Adult Subjects

The purpose of this study is to assess how fast pegilodecakin gets into the blood stream and how long it takes the body to remove it, when given as a solution formulation via a prefilled syringe (PFS) versus from a vial drawn into a conventional syringe. Information about side effects will be collected. The study is open to healthy participants. Total participant duration in trial is approximately 42 days.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

Yes
