A Study to Explore Pharmacokinetics/Pharmacodynamics and Safety of Tegoprazan BID Dosing in Healthy Subjects

Phase 1

• Conditions: Healthy
• Interventions: Drug: Tegoprazan dose B or placebo; Drug: Tegoprazan dose A or placebo; Drug: Tegoprazan dose C or placebo; Drug: Tegoprazan dose D or placebo

• Registration Number: NCT04587011
• Lead Sponsor: HK inno.N Corporation

Brief Summary

The main purpose of this study is to explore the pharmacokinetics, pharmacodynamics and safety after twice-daily dosing of tegoprazan tablets in healthy subjects.

Detailed Description

* To explore the pharmacokinetics, pharmacodynamics and safety in accordance with the dose escalation when tegoprazan is given orally twice daily for 3 days in healthy subjects.

* To compare the pharmacodynamics and safety of tegoprazan oral administration and esomeprazole infusion for 24 hours

   • Subjects who are determined by the investigator to have past history of gastrointestinal diseases (ex.: gastritis, GERD, Crohn's disease, ulcers etc.) or abdominal surgery (except simple appendectomy or herniotomy) that may affect the IP absorption.

2. Diagnostic test and electrocardiogram (ECG)

   • If H. pylori test result is positive at screening
   • If the AST or ALT value is more than 1.25 times the upper limit of normal under the screening test
   • If the total bilirubin value is more than 1.5 times the upper limit of normal under the screening test

   • Subjects with history of substance abuse or positive results from drug screening test.

4. Contraindicated drugs/foods

   • Subjects who have been taking any medications (including herbal medicines) or on an abnormal diet (ex: consuming more than 1L of grapefruit juice per day, large amounts of garlic, broccoli and kale, etc.) that can affect the absorption, distribution, metabolism and excretion of the IP within 28 days from the first IP administration date
   • Subjects who took any prescription drugs(ETC) or any over-the-counter drugs(OTC) within 10 days from the first IP administration date
   • Subjects who participated in other clinical trials or bioequivalence test and received other investigational product within 6 months from the first day of the IP administration (allowed to participate only if the other investigational product(s) was(were) not taken)

5. Blood donation and transfusion

   • Subjects who donated whole blood within 60 days from the first day of the investigational product administration
   • Subjects who received blood transfusion or made apheresis blood donation within 30 days from the first day of the IP administration

6. Pregnancy, Breastfeeding, and Contraception

   • Women who are pregnant, breast-feeding or have positive result on pregnancy test.
   • Subjects who are unable to use medically proven dual contraceptive methods or medically acceptable contraceptive method (intrauterine device with proven pregnancy failure rate, concurrent use of physical barrier method and spermicide, vasectomy, tubectomy/ligation, and hysterectomy, etc.) by the subject or spouse or partner from the screening date to 30 days after the last IP administration date.

7. Others
