A Study to Assess LY4100511 (DC-853) in Healthy Adult Participants

April 22, 2025 updated by: DICE Therapeutics, Inc., a wholly owned subsidiary of Eli Lilly and Company

A Phase 1, Single-Center, Open-Label, 3-Cohort, Fixed-Sequence, Drug-Drug Interaction Study To Assess The Pharmacokinetics Of LY4100511 (DC-853) When Orally Administered Alone, When Coadministered With Itraconazole, Fluconazole, Or Carbamazepine In Healthy Adult Participants

The main purpose of this study is to assess the effect of multiple doses of itraconazole, fluconazole, and carbamazepine on single dose pharmacokinetic of LY4100511 (DICE-853) in healthy participants. The study will also evaluate the safety and tolerability of LY4100511 (DICE-853) with itraconazole, fluconazole, and carbamazepine.
