E.3 | Principal inclusion criteria |
At Visit 1/Screening Visit
1. Patient has T2DM and is ≥18 and ≤79 years of age on the day of signing informed consent.
2. Patient is a male, or a female who is highly unlikely to conceive as indicated by at least one “yes” answer to the following questions:
a) Patient is not of reproductive potential. A female patient who is not of reproductive potential is defined as one who has either (1) reached natural menopause (defined as ≥6 months of spontaneous amenorrhea with serum FSH levels in the postmenopausal range as determined by the laboratory, or ≥12 months of spontaneous amenorrhea in women >45 years of age), (2) undergone a bilateral oophorectomy and/or hysterectomy, or bilateral tubal ligation.
b) Patient is of reproductive potential and agrees to remain abstinent or use (or have their partner use) two acceptable methods of birth control within the projected duration of the study and for 14 days after the last dose of study medication. Acceptable methods of birth control are: hormonal contraceptives, intrauterine device (IUD), diaphragm with spermicide, contraceptive sponge, condom, vasectomy.
3. Patient understands the study procedures, alternative treatments available and risks involved with the study, and voluntarily agrees to participate by giving informed written consent.
