Detailed Description

  1. Cohort 1 is designed to evaluate the effect of food on the pharmacokinetics and safety/tolerability of JPI-547 in healthy Korean and Caucasian participants under fasted and fed conditions.
  2. Cohort 2 is designed to explore the effect of ethnicity on the pharmacokinetics and safety/tolerability of JPI-547 in healthy Chinese participants after a single oral administration.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Korean/Caucasian Participants: JPI-547 Fed/Fasted Crossover
Healthy Korean and Caucasian male participants receive a single oral dose of JPI-547 in each treatment period under fed and fasted conditions in a crossover design.
JPI-547 is administered orally as a single dose per administration.
Experimental: Chinese Participants: JPI-547 Fasted
Healthy Chinese male participants receive a single oral dose of JPI-547 under fasting conditions.
JPI-547 is administered orally as a single dose per administration.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Maximum Plasma Concentration (Cmax) of JPI-547
Time Frame: Pre-dose through 120 hours post-dose after each administration, based on 17 PK samples per administration; assessed up to Day 20 for the Korean/Caucasian fed/fasted crossover arm and up to Day 6 for the Chinese fasted arm.
Cmax is defined as the maximum observed plasma concentration of JPI-547 after a single oral administration.
Pre-dose through 120 hours post-dose after each administration, based on 17 PK samples per administration; assessed up to Day 20 for the Korean/Caucasian fed/fasted crossover arm and up to Day 6 for the Chinese fasted arm.
Area Under the Plasma Concentration-Time Curve From Time Zero to the Last Quantifiable Concentration (AUClast) of JPI-547
Time Frame: Pre-dose through 120 hours post-dose after each administration, based on 17 PK samples per administration; assessed up to Day 20 for the Korean/Caucasian fed/fasted crossover arm and up to Day 6 for the Chinese fasted arm.
AUClast is defined as the area under the plasma concentration-time curve from time zero to the last quantifiable concentration of JPI-547 after a single oral administration.
Pre-dose through 120 hours post-dose after each administration, based on 17 PK samples per administration; assessed up to Day 20 for the Korean/Caucasian fed/fasted crossover arm and up to Day 6 for the Chinese fasted arm.
Number of Participants With Abnormalities in Safety and Tolerability Assessments
Time Frame: From the first administration of JPI-547 until the Post-Study Visit; assessed up to Day 32 for the Korean/Caucasian fed/fasted crossover arm and up to Day 18 for the Chinese fasted arm.
Safety and tolerability will be assessed by monitoring adverse events, including subjective and objective symptoms, physical examinations, vital signs, 12-lead electrocardiograms, and clinical laboratory tests after a single oral administration of JPI-547.
From the first administration of JPI-547 until the Post-Study Visit; assessed up to Day 32 for the Korean/Caucasian fed/fasted crossover arm and up to Day 18 for the Chinese fasted arm.
