(4) HbA1c (HbA1c) ≥ 7.0% and ≤ 11% during screening.
(5) Body mass index (BMI) ≥ 18.5 kg/m2.
(6) There is no birth plan within 6 months from the signing of informed consent to the last administration, and those who voluntarily take effective contraceptive measures and have no sperm donation plan. Fertile women are not breastfeeding, and the screening and baseline pregnancy tests must be negative.
