Brief summary: The main purpose of this study is to evaluate pharmacokinetics/pharmacodynamics and safety/tolerability of IN-C005 after oral administration in healthy Korean and Caucasian male subjects.

Detailed description: \[Pharmacokinetic Assessments\]: Plasma concentrations of IN-C005 and its metabolite will be measured

   * Primary endpoints: Cmax and AUClast of IN-C005
   * Secondary endpoints: AUClast, Cmax, AUCinf, Tmax, t½, CL/F, and Vd/F of M1; AUCinf, Tmax, t½, CL/F, and Vd/F of IN-C005
2. Multiple Dosing Group (Caucasian Subjects)

   * Primary endpoints: Cmax, AUClast, Cmax,ss, and AUCτ,ss of IN-C005
   * Secondary endpoints: For M1, AUClast, Cmax, Cmax,ss, AUCinf, AUCτ,ss, Tmax, Tmax,ss, t½, CL/F, and Vd/F; for IN-C005, AUCinf, Tmax, Tmax,ss, Cmin,ss, t½, CL/F, Vd/F, Cav,ss, CLss/F, Vss/F, PTF (peak to trough fluctuation), and R (accumulation ratio)

\[Pharmacodynamic Assessments\]:

1. Single Dosing Group (Korean Subjects)

   * Intragastric pH

     * Percent (%) duration of pH ≥4 in 24 hrs
     * Mean pH

     * Change in pH from baseline to post-dose (Δduration %, Δmean pH, Δmedian pH, etc.)
   * Serum gastrin level

     * AUEGlast
     * Gmax
     * Change in gastrin level from baseline to study treatment (1d, 8d, and 15d)(ΔAUEGlast, ΔGmax, etc.)
2. Multiple Dosing Group (Caucasian Subjects)

   * Intragastric pH

     * Percent (%) duration of pH ≥4 in 24 hrs
     * Mean pH

     * Change in pH from baseline to post-single dose and post-multiple doses (Δduration %, Δmean pH, Δmedian pH, etc.)
   * Serum gastrin level

     * AUEGlast
     * Gmax
     * Change in gastrin level from baseline to 1d and 7d (ΔAUEGlast, ΔGmax, etc.)

\[Safety Assessments\] \<Single Dosing Group (Korean Subjects) and Multiple Dosing Group (Caucasian Subjects)\>

1. AEs will be monitored with observable/objective symptoms, etc.

* Subjects who received any prescription drug or herbal medication within 2 weeks of or any over-the-counter (OTC) drug, dietary supplements, or vitamins within 1 week of scheduled first dose or subjects who are expected to receive such medication during the study. (Note: a subject may participate in the study at the discretion of the investigator, provided that the subject meets all the other criteria).
* Subjects who participated in any other clinical study or bioequivalence study and received investigational product within 6 months prior to the scheduled first dose.
* Subjects who have donated whole blood within 2 months prior to the scheduled first dose, or have donated blood components or received transfusion within a month prior to the scheduled first dose.
* Excessive caffeine intake (\> 5 units/day), continued use of alcohol (\> 21 units/week, 1 unit = 10 g of pure alcohol), or inability to stop drinking while hospitalized.
* Positive result for cotinine on urine drug screening test or inability to quit smoking throughout the study.
* Subjects who have taken grapefruit-containing foods during the period from 24 hours (hrs) before hospitalization to discharge, or are unable to avoid grapefruit-containing foods during this period.

* Subjects who are unable to use medically acceptable contraceptive methods throughout the study.

  ► Medically acceptable contraceptive methods include:

  ① Use of intrauterine device with a proven birth control failure rate by the spouse (or partner);

  ② Simultaneous use of (male or female) barrier method and spermicide; and

  ③ Surgical sterilization of the subject or his partner (e.g., vasectomy, salpingectomy, tubal ligation, or hysterectomy).
* Subjects who are determined ineligible for study participation by the investigator for other reasons such as clinical laboratory abnormalities.
