Brief Summary

The purpose of this study is to investigate the safety and drug interaction of DHP2302R1 and DHP2302R2 when administered alone versus in combination in healthy South Korean adult participants.

Detailed Description

This is a phase 1 open-label, multiple doses, 6-sequence, 3-period, and crossover study to evaluate the safety and pharmacokinetic drug interaction following 7 days of DHP2302R1 75 mg and DHP2302R2 50 mg in healthy South Korean adult participants.

A total of 42 participants, 7 per 6 groups, will enroll in the study. The participants will take 7 days of DHP2302R1 75 mg, DHP2302R1 50 mg alone or in combination, and 2 weeks of washout period at each period.
