Renal Impairment Study for Oral EC5026

The goal of this Phase 1 clinical trial is to assess single dose pharmacokinetics of oral EC5026 in a population with chronic kidney disease. The main questions it aims to answer are: 1. To determine if the PK of a single 8 mg dose of EC5026, administered orally, in adult participants with varying severity of CKD differs from age-matched healthy participants with normal kidney function. 2. To determine if a single 8 mg dose of EC5026, administered orally, in adult participants with varying severity of CKD is safe and well tolerated. Researchers will compare a single 8 mg dose of oral across participants with varying degrees of kidney function impairment (either normal kidney function, or stage 3b chronic kidney disease \[CKD\], or state 4/5 CKD). Participants will be asked to take a single oral dose of EC5026 and will be monitored with PK laboratory assessments and safety assessments (including physical exams, vital signs, electrocardiograms, and others).
