Subjects on hormonal contraception must be stabilized on the same type for at least three months prior to screening and must not change the method during the study. A sterile sexual partner is NOT considered an adequate form of birth control.
11. All male Subjects must agree to use accepted methods of birth control with their partners, from the day of the first dose administration to 30 days after the last administration of study drug. Abstinence is an acceptable method of birth control. Female partners should use an acceptable method of birth control as described in the above Item Number 10.
