   ① Surgical infertility (e.g., bilateral tubal ligation, vasectomy)

   ② Hormonal contraceptives (Hormone releasing IUD, implantable form, patch, oral hormone)

   ③ Double-barrier method (concomitant use of two of the following: IUD, male or female condom, contraceptive diaphragm, contraceptive sponge, cervical cap, spermicide) Periodic abstinence (e.g., calendar, ovulation date, basal body temperature, post-ovulation methods) and coitus interruptus are not permitted as appropriate contraceptive methods, and effective contraceptive methods must be kept being used during the course of the clinical study.

7. Those who are scheduled to have organ transplantation

8. Those who have laboratory test results that fall under the following values at screening ① ALT or AST ≥5 times the upper limit of normal (ULN)

   ② eGFR < 30 mL/min/1.73m2

   ③ platelets < 50,000/mm3
