At the time of study entry, and at any time during the study when a
female subject of childbearing potential's contraceptive measures or
ability to become pregnant changes, the Investigator will educate the
subject regarding abstinence or contraception options and the correct
and consistent use of effective contraceptive methods in order to
successfully prevent pregnancy.

at Screening and Baseline. All FCBP who engage in activity in which
conception is possible must use one of the approved contraceptive+
options described below:

contraception (for example, birth control pills, intravaginal ring,
transdermal patch, injection, implant); intrauterine device (IUD); tubal
ligation; or partner's vasectomy.
