  • The use by women of childbearing potential, as well as by men and their partners of childbearing potential, of one of the following contraceptive methods during the study and for 6 months after the end of administration of the investigational medicinal product: a. Highly effective methods that are user-independent, with a failure rate of <1% per year when used consistently and correctly: i. progestogen-only hormonal contraceptive implants associated with inhibition of ovulation; ii. intrauterine device (IUD); iii. intrauterine hormone-releasing system (IUS); iv. bilateral tubal occlusion/ligation; v. a partner with documented vasectomy (provided that the partner is the sole sexual partner of the woman of childbearing potential and absence of sperm in semen has been confirmed); b. Highly effective user-dependent methods, with a failure rate of <1% per year when used consistently and correctly: i. progestogen-only hormonal contraception associated with inhibition of ovulation (oral or injectable); ii. combined (oestrogen- and progestogen-containing) hormonal contraception associated with inhibition of ovulation: oral intravaginal transdermal injectable c. complete declared sexual abstinence. The use of the above-mentioned methods also applies to women and men who have undergone surgical sterilisation within 6 months prior to the date of signing the informed consent form. A woman of childbearing potential is defined as a woman from menarche until the postmenopausal period (defined as age >45 years and complete absence of menstruation for at least 12 months with no medical cause), unless she is permanently infertile (following prior sterilisation – hysterectomy, bilateral salpingectomy, or bilateral oophorectomy). For women in the menopausal period, the criterion of the last menstruation occurring at least 12 months prior to the date of signing the informed consent form applies in order for them to be considered not of childbearing potential. Women and men who have undergone surgical sterilisation more than 6 months prior to signing the informed consent form are considered not of childbearing potential.
