Approximately 30 HVs will be enrolled in the multiple ascending dose study. All participants in Part 2 will received KHN702 or placebo once daily for continuous 7 days (QD x 7d) in a double-blind manner.

The safety and tolerability will be evaluated by monitoring and assessment of AEs, clinical laboratory tests (hematology, urinalysis, biochemistry, coagulation, etc.), physical examination findings, etc.
