1. Research Purpose: To evaluate the safety, tolerability, pharmacokinetic/pharmacodynamic properties of J2H-1702 (a candidate for treatment of non-alcoholic steatohepatitis) in healthy men.
2. Design: A dose block-randomized, double-blind, placebo controlled, single- and multiple dosing, dose-escalation phase 1 clinical trial

Subjects in all dose groups will be randomized to the study group (J2H-1702 group) and the control group (Placebo group) in a 8:2 ratio. Adverse event (AE) collection, physical examination, vital signs, ECG, clinical laboratory tests, etc. will be performed to assess the safety and tolerability, and blood and urine sampling will be performed to assess the PK/PD characteristics. In addition, blood sampling for mass cytometry (multiple administration study) and baseline fibroscan will be performed for the exploratory evaluation.

Inclusion Criteria:

1. A healthy male adult within the range of 19 to 45 years old
2. BMI=18.0~27.0kg/m2 (Body mass index, BMI)
3. A subject confirmed to be clinically healthy based on the medical history, physical examination, vitals signs, ECG, and appropriate clinical laboratory tests
4. A subject who his spouse or partner agrees to use dual contraceptive methods and not to donate sperms
5. A subject who has voluntarily agree to participate in the study

Exclusion Criteria:
