LH-001 vs Placebo in Healthy Participants
- Registration Number
- NCT06546449
- Lead Sponsor
- Chien-Liang Lin
- Brief Summary
The purpose of this clinical trial is to evaluate the safety and tolerability of LH-001 when administered as an oral, single or multiple dose(s) at ascending dose levels in healthy participants.
- Detailed Description
This is a first-in-human, randomized, double-blinded, placebo-controlled study. This study consists of two parts: (1) single ascending doses in 4 cohorts (SAD) and (2) 14-day multiple ascending doses in 3 cohorts (MAD). Cohorts may be added or removed if needed due to safety considerations or deviations of actual PK parameters from predicted values.
The SAD study consists of a screening visit, a 2-day inpatient stay (Day 1-2), a return visit for safety assessments on Day 3, Day 4, and Day 8.
The MAD study consists of a screening visit, a 2-day inpatient stay (Day 1-2), daily return for dosing and safety assessments (Day 3-13), a 2-day inpatient stay (Day 14-15), and a follow-up by phone (Day 21).
