• Be currently enrolled in an investigational drug or device study or have used an investigational drug or device within 30 days prior to Visit 1 and during the treatment period.

• Be a female who is pregnant, nursing, or planning a pregnancy at Visit 1. Be a woman of childbearing potential who is not using an acceptable means of birth control; acceptable methods of contraception include: hormonal - oral, implantable, injectable, or transdermal contraceptives; mechanical - spermicide in conjunction with a barrier such as a diaphragm or condom; IUD; or surgical sterilization of partner.
