A Study to Investigate IGT-303 in Healthy Volunteers and Participants With Chronic Kidney Disease

This study is testing the safety of a new drug called IGT-303 in both healthy adults and people with chronic kidney disease (CKD) — a condition where the kidneys gradually lose their ability to filter waste from the blood.
