The purpose of this study is to evaluate how well LY4005130 is tolerated and what side effects may occur in healthy participants. The study drug will be administered either subcutaneously (SC) (under the skin) or intravenously (IV) (into a vein in the arm). Blood tests will be performed to check how much LY4005130 gets into the bloodstream and how long it takes the body to eliminate it. Part A for the single-ascending doses (SAD) of the study will last about 12 weeks with 9 visits. Part B for the multiple-ascending doses (MAD) of the study will either last about 16 weeks with 13 visits or 26 weeks with 14 visits not including screening.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Eli Lilly and Company (LLY) is the sponsoring company for this trial. BiotechSign currently grades this company C (54/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
