Clinical Trial Summary

This is a first in human clinical trial with HHT120. The purpose of this study is to characterize the safety, pharmacokinetic (PK) and Pharmacodynamic (PD) profile of single and multiple twice-daily doses of HHT120 in healthy Subjects and to assess the effects of food on the PK profile of single-dose of HHT120 in healthy Subjects.

Description:

There are 3 parts of the study:

Part 1: Single asending dose trial; Part 2: Multiple asending dose trial; Part 3: Food effect trial ( 2-Period Crossover)
