Phase 1 study evaluating the safety, tolerability, and pharmacokinetics of lobeglitazone administered as M107 Orally Disintegrating Tablet and Duvie tablet in healthy adult participants under fasted and fed conditions.

This is a Phase 1, single-center, parallel group study designed to determine the single-dose safety and PK profile of lobeglitazone from M107 ODT and Duvie, both administered orally in healthy adult volunteers.

Participants will be enrolled in 1 of 3 cohorts conducted in parallel:

Cohort 1 (Crossover): A single dose of Duvie oral tablet (0.415 mg; fasted) on Day 1 followed by a single dose of M107 ODT (0.4 mg; fasted) on Day 8, or vice versa, based on their random assignment with a 7-day washout between each dose.

Cohort 2 (Crossover): M107 ODT (0.8 mg; fasted) followed by M107 ODT (0.8 mg; fed) after a 7-day washout.

Cohort 3: M107 ODT (1.2 mg fasted) Participants in this cohort will receive M107 ODT 1.2 mg after a 10-hour fast.

A total of up to 24 participants are planned to be enrolled, 8 in each cohort, in order to ensure 6 evaluable participants in each cohort. At least 2 males and 2 females are to be enrolled in each cohort.
