A Single-Ascending and Repeated Subcutaneous Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of LY3849891 in Participants With Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) Who Have the PNPLA3 I148M Genotype
The main purpose of this study is to evaluate the safety and tolerability of the study drug LY3849891 in participants with metabolic dysfunction-associated steatotic liver disease (MASLD) who have the patatin-like phospholipase domain-containing protein 3 (PNPLA3) I148M genotype. Blood tests and magnetic resonance imaging of the liver will be performed to determine the effects of LY3849891 on MASLD and assessment of resolution of liver fibroinflammation. Blood tests will also determine how long it takes the body to eliminate LY3849891. This is a 2-part study and may last up to 32 weeks for each participant and may include 12 visits in parts A and B.
• Participants must have a body mass index (BMI) within the range greater than or equal to (≥) 25 and less than (\<) 50 kilogram per square meter (kg/m²) inclusive
• Participants must have liver fat content ≥10% in Part A and ≥8% for Part B as determined by MRI-PDFF
• Participants must be carriers of the PNPLA3 I148M allele
• Participants with or without type 2 diabetes mellitus (T2DM)
• o For participants with T2DM, hemoglobin A1c (HbA1c) \<8% in Part A and \<9% in Part B
• Male participants agree to use an effective method of contraception for the duration of the study and for 90 days after the last dose of study intervention
• Women not of childbearing potential may participate and include those who are: infertile due to surgical sterilization (hysterectomy, bilateral oophorectomy, or tubal ligation), congenital anomaly such as Mullerian agenesis; or those who are postmenopausal
