Summary
This early-stage trial tests an experimental drug called RFUS-949, taken as a tablet, to see if it is safe and how it behaves in the body. The study involves 28 healthy Chinese adults aged 18 to 45. Participants receive either the drug or a placebo daily for 6 days, with close monitoring for side effects and blood tests to measure drug levels.
