• Non-hormone releasing intrauterine device in place for at least 3 mo prior to the first dose of study drug with either a physical (e.g., condom, diaphragm) or a chemical (e.g., spermicide) barrier method from the time of screening through 14 days following the last dose of study drug.
• A physical barrier method (e.g., condom, diaphragm) with a chemical barrier method (e.g., spermicide) for at least 14 days prior to the first dose of study drug and until 14 days after the last dose of study drug.
• In addition, female subjects of childbearing potential will be advised to remain sexually inactive or to keep the same birth control method or for at least 14 days following the last dose of study drug.
• For a female of non-childbearing potential: must have undergone one of the following sterilization procedures at least 6 mo prior to the first dose of study drug:
