1. Study Objective: The objective of this phase 1 clinical trial is to evaluate the safety, tolerability, pharmacokinetic/pharmacodynamic characteristics and food effect of HSG4112 after oral administration in healthy male subjects. 2. Study Design and Plan: This study is a dose-block randomized, double-blind, placebo-controlled, single and multiple dosing, dose-escalation phase 1 clinical trial. A unique randomization number will be assigned to each subject deemed eligible to participate in the study based on the inclusion/exclusion criteria. Each subject will be randomized to one of the six groups for the single ascending dose (SAD) study or one of the three groups for the multiple ascending dose (MAD) study. Each dose group will consist of ten subjects, and among the ten subjects, eight subjects will be randomized to receive HSG4112 and two subjects will be randomized to receive placebo. The subjects will be studied in a double-blind manner and will receive the investigational product (i.e., HSG4112 or placebo) via once-daily oral administration. The dosing duration for the MAD study is 14 days. When escalating the dose, the Investigator will review all of the available safety data from the preceding dose in a blinded manner to ensure if it is safe to escalate the dose. In order to evaluate safety and tolerability, assessments, such as vital signs, 12-lead electrocardiogram, laboratory test, semen analysis (MAD study only), physical examination, and adverse event monitoring will be performed. Blood samples will be collected to evaluate the pharmacokinetic/pharmacodynamic characteristics of HSG4112.
