13. Persons of reproductive potential must agree to use an adequate method of contraception throughout treatment and for at least 6 months after study drug is stopped.

    \*Highly effective method includes: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation 1 (oral/ intravaginal/ transdermal); progestogen-only hormonal contraception associated with inhibition of ovulation 1 (oral/injectable/implantable); intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; vasectomised partner; sexual abstinence
