A highly effective method of contraception or birth control (failure rate less than 1% per year when used consistently and correctly) must be practiced. The subject should be informed of the potential risks associated with becoming pregnant while enrolled in this clinical trial. Reliable methods for this trial are: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable), intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, sexual abstinence or vasectomized sexual partner. Abstinence is only accepted as true abstinence: when this is in line with the preferred and usual lifestyle of the patient. (Periodic abstinence [e.g. calendar, ovulation, symptothermal, post-ovulation methods and withdrawal] are not acceptable methods of contraception.) Postmenopausal (no menses for at least 1 year without alternative medical cause) or surgically sterile female subjects (tubal ligation, hysterectomy or bilateral oophorectomy) may be enrolled.\n- Male patients must practice true abstinence or agree to use a condom during sexual contact with a pregnant woman or a woman of childbearing potential for the study duration."}
