What this trial studies

This Phase 1 trial gives LY4088044 or placebo to overtly healthy adults to characterize safety, tolerability, and how the drug moves through and is eliminated from the body. The drug is administered either subcutaneously (SC) or intravenously (IV), with blood sampling for pharmacokinetics and routine safety labs and cardiac monitoring. The study includes multiple parts (A, B, and C) and may last up to about 92 weeks excluding screening, with safety and lab-based eligibility criteria applied at enrollment. Participants must meet BMI and laboratory limits and will be excluded for pregnancy/lactation, significant kidney impairment, ECG abnormalities, certain hemoglobin issues, heavy smoking, or illicit drug use.

Who should consider this trial

Good fit: Ideal candidates are overtly healthy adults with BMI between 18.5 and 30 kg/m² who have normal labs, normal ECG, adequate kidney function, are not pregnant or breastfeeding, and can comply with study visits.

Not a fit: People with active medical conditions, pregnancy or lactation, low hemoglobin or evidence of iron disorders, impaired kidney function (eGFR <90 mL/min/1.73 m²), ECG abnormalities, heavy smokers, or recent illicit drug use are unlikely to be eligible or benefit from participation.

Why it matters

Potential benefit: If successful, the results could show LY4088044 is safe and has predictable blood levels, enabling future patient studies for conditions the drug may target.

How similar studies have performed: This is a standard first-in-human PK/safety approach commonly used for experimental drugs and has been successful in establishing dosing and safety for many therapies, though LY4088044 itself is early-stage.
