salpingectomy, or bilateral oophorectomy.
b. Non pregnant female of childbearing potential must agree to using a highly
effective contraception method during treatment and for 30 days
following treatment that can achieve a failure rate of less than 1% per
year when used consistently and correctly. The following are considered highly effective birth control methods:

contraception associated with inhibition of ovulation, which may be oral,
intravaginal, or transdermal

ovulation, which may be oral, injected, or implanted

− Bilateral tubal occlusion
− Vasectomized partner, provided that partner is the sole sexual partner
of the WOCBP trial subject and that the vasectomized partner has
received medical assessment of the surgical success.
− Sexual abstinence. The reliability of sexual abstinence needs to be
evaluated in relation to the duration of the clinical study and the
preferred and usual lifestyle of the subject. Periodic abstinence is not
acceptable.
c. A male subject with a pregnant or non-pregnant female of childbearing potential partner must agree to using condoms during treatment and for 30 days following treatment
