  • If the subject is female and of reproductive potential, she has a negative serum pregnancy test at Screening and a negative urine pregnancy test on Day 0.
  • If the subject is of reproductive potential, s/he agrees to abstain from reproductive cell donation, per below, and, if ever heterosexually active, to use dual effective/highly effective contraception (including at least one effective and at least one highly effective contraceptive method; Section 9.2.1) from Screening through the End of Trial Visit.
