Bioequivalence Study Between YHP2406 and YHR2501 in Healthy Subjects

An Open-label, Randomized, Fasting, Single-dose, Oral Administration, 2- Sequence, 2-period, Crossover Study to Evaluate Bioequivalence Study Between YHP2406 and YHR2501 in Healthy Subjects

A randomized, open-label, single-dose, 2-sequence, 2-period, crossover clinical trial to investigate the bioequivalence between YHP2406 and YHR2501 in healthy volunteers

Study Overview

• Status: Completed
• Conditions: Healthy Subjects
• Intervention / Treatment: Drug: YHP2406; Drug: YHR2501

Detailed Description

62 healthy subjects will be randomized to one of the 2 groups in the same ratio.

Subjects in group 1 will be administered "comparator" and "YHP2406" by crossover design on period 1, 2. Subjects in group 2 will be administered "YHP2406" and "comparator" by crossover design on period 1, 2.
