Brief summary: This is a Phase I, first-in-human, randomised, double-blinded, placebo-and active-controlled study to assess the safety, tolerability, PK, PD, efficacy, and food-effect of IDG-16177 in healthy male subjects and patients with T2DM at different dose levels.

Detailed description: This study consists of 2 parts: Part 1 is a dose-escalation study in healthy male subjects in single ascending dose (SAD) (Part 1.1) including food-effect and multiple ascending dose (MAD) (Part 1.2) cohorts to determine the highest allowable dose (HAD) for patients with T2DM; and Part 2 is a placebo- and active-controlled efficacy exploration in patients with T2DM, insufficiently controlled with metformin alone.
