Multiple Ascending Dose Study of NH102 in Healthy Subjects

The purpose of this study is to assess the safety, tolerability and pharmacokinetics (PK) of NH102 when administered as multiple oral dose at escalating dose levels in healthy participants.

The drug being tested in this study is called NH102. NH102 is being tested to treat people who have depression. This study will look at the safety, tolerability and PK of NH102 in healthy participants. The study may enroll up to 30-40 participants. Participants will be randomly assigned within each cohort to receive NH102 or placebo which will remain undisclosed to the participants and study doctor during the study (unless there is an urgent medical need). The study consists of four dose groups: 3 mg (fixed dose), 10 mg (fixed dose), 15 mg (starting at 6 mg, then escalated to 10 mg, and finally to 15 mg), and 20 mg (starting at 10 mg, then escalated to 15 mg, and finally to 20 mg). Each group enrolls 10 subjects, with 8 receiving NH102 and 2 receiving placebo. For the third and fourth dose groups (15 mg and 20 mg) that follow a titration dosing regimen, each includes 2 sentinel subjects (both male). The two sentinel subjects may be dosed simultaneously. Only after both sentinel subjects complete all 17 doses (with a single dose administered on Day 9) and are observed for at least 24 hours, along with preliminary confirmation of safety, may the remaining subjects in the same dose group proceed with dosing.
