T2DM (Type 2 Diabetes Mellitus)
Conditions
Brief summary
This trial includes two parts: a food effect (FE) study and a multiple-dose pharmacokinetic (PK) study. The FE study is a randomized, open-label, two-period, two-sequence crossover study designed to evaluate the effect of a high-fat meal on the PK of a single oral dose of Chiglitazar/Metformin extended-release tablets in healthy adult Chinese participants. The multiple-dose PK study is an open-label study designed to evaluate the PK characteristics of Chiglitazar/Metformin extended-release tablets in healthy adult Chinese participants following multiple oral doses.
Interventions
a single dose of Chiglitazar/Metformin extended-release tablets under fasting conditions
a single dose of Chiglitazar/Metformin extended-release tablets after a high-fat meal
a single dose on Day 1, once-daily consecutive doses from Day 4 to Day 10
