Female patients of childbearing potential who are sexually active must agree to use a barrier method in addition to highly effective methods of contraception throughout the study and for 90 days following the last dose of study treatment. Germany only: Premenopausal female patients of childbearing potential must have a negative serum pregnancy test within 10 to 14 days and a second negative serum test within 24 hours prior to the first dose of study treatment. Premenopausal female patients of childbearing potential who are sexually active must agree to use a barrier method in addition highly effective methods of contraception throughout the study and for 90 days following the last dose of study treatment.

Male patients must agree not to donate sperm during the study treatment period and for at least 90 days after the last dose of selinexor treatment.
You likely can't join if
