18. Subjects who did not consent to use an effective contraceptive (e.g., use of condoms) alone or in combination between the day of hospitalization and 3 months after the end of the study drug administration;
19. Pregnant, lactating, possibly pregnant subjects/women (subjects/women of childbearing potential with positive pregnancy test at screening or Day -1, or with negative pregnancy test at screening and Day -1 not using any contraceptive methods), or unwilling to use adequate contraception according to the physician's instructions. Amenorrhea for ≥12 months after the last menstrual period without an alternative medical cause is considered as non-childbearing potential;
