A Phase 1 Study to Assess the Safety and Effects of Single and Multiple Doses of KS101 in Healthy Volunteers

This study is the first clinical trial involving study drug KS101. The goal of this clinical trial is to investigate whether KS101 is safe, whether it causes side effects, and how KS101 is broken down in the body, in healthy participants. This information will be used to learn more about KS101 and to determine the most effective dose for age related diseases such as chronic kidney disease and Alzheimer's Disease, with the fewest unwanted side effects. There are 3 parts to this study. In Part 1, participants will take KS101 or a placebo once and will stay in the study centre for a 4-night inpatient stay. Participants will return for outpatient visits on Days 8 and 29. In Part 2, participants will take KS101 twice, once after a meal and once without a meal and will stay in the study centre for a 7-night inpatient stay. Participants will return for outpatient visits on Days 11 and 32. In Part 3, participants will take KS101 or a placebo once daily for 5 days and will stay in the study centre for an 8-night inpatient stay. Participants will return for outpatient visits on Days 12 and 33.
