- For female participants: Negative pregnancy tests at Screening and Day 0, in conjunction with a menstrual and contraceptive history indicating a low probability of pregnancy in the opinion of the physician. Females of childbearing potential will be required to be correctly using an efficacious hormonal method of contraception or intrauterine device for at least 1 month before randomisation and during the on-study phase to Day 30. Barrier methods of contraception will not be considered acceptable for study entry. Female participants of child-bearing potential will sign an agreement that contraception will be correctly practised during the specified periods and will specify the method used. Female participants unable to become pregnant must have this documented (e.g., tubal ligation, hysterectomy or postmenopausal [at least one year since last menstrual period]).
