- Women and men of reproductive potential must agree to use highly effective contraception when sexually active. This applies for the period between signing of the informed consent and 30 days after the last administration of study drug. Highly effective contraception includes a hormonal contraception with implants or combined oral contraceptives, certain intrauterine devices, bilateral tubal ligation, hysterectomy, or vasectomy of the partner. In addition, the use of condoms for subjects or their partners is required.
