Has a hematopathy (e.g. hemolytic anemia, drepanocytosis) that may interfere with the HbA1c test.~10. Has other liabilities (e.g. drug abuse, alcoholism or mental disorder) that may hinder the participant to follow and complete the study.~11. Has participated in another clinical study within the past 90 days or has received any investigational compound within 30 days prior to randomization.~12. Is unsuitable for this study in the opinion of investigators.~13. Has a disease need to use other taboo or caution drugs that is not listed in this study.~14.
