10. Female subjects of childbearing potential must test negative for pregnancy.
11. Male and female subjects of childbearing potential and at risk for pregnancy must agree to use two highly effective methods of contraception throughout the study and for at least 3 months after the last dose of assigned treatment. A subject is of childbearing potential if, in the opinion of the investigator, he/she is biologically capable of having children and is sexually active. (Please refer to Appendix 6 for
specific requirements for subjects enrolled in Czech Republic, Estonia,
Germany, Hungary, Lithuania, Latvia, Romania, Spain and the United
Kingdom).
12. Female subjects who are not of childbearing potential (ie, meet at least one of the following criteria):
a. Have undergone a documented hysterectomy and/or bilateral oophorectomy;
b. Have medically confirmed ovarian failure or;
c. Achieved post-menopausal status, defined as: cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; and have a serum follicle-stimulating hormone (FSH) level within the laboratory’s reference range for postmenopausal females
13. Subjects must screen negative for active tuberculosis or inadequately treated tuberculosis infection (active or latent) as evidenced by the following:
a. Negative QuantiFERON Gold®TM In-Tube test performed at screening
- This is required unless the subject has been adequately treated for active or latent tuberculosis or a negative QuantiFERON Gold®TM In-Tube test was
previously performed and documented within the 3 months prior to screening.
- A negative tuberculin skin test (TST) is one that is <5 mm induration and can be substituted for the QuantiFERON Gold ® TM In-Tube test only if the
central laboratory is unable to perform the test or the test is reported as indeterminate after at least 2 successive attempts.
- It is strongly recommended that subjects with a history of Bacille Calmette Guérin (BCG) vaccination be tested with the QuantiFERON Gold®™ In-Tube test.
b. Chest radiograph (or chest computed tomography (CT) scan, if available) taken at screening without changes suggestive of active tuberculosis (TB) infection, unless previously performed and documented within 3 months prior to screening.
c. No history of tuberculosis infection unless one of the following is documented:
- Subject with prior or current latent tuberculosis has no evidence of active tuberculosis and must be taking or have completed an adequate course of
therapy for latent tuberculosis in a locale where rates of primary multi-drug resistant TB infection are <5%, and a chest radiograph is negative for active disease; the chest radiograph must be obtained at screening or, if previously performed and documented, within 3 months prior to screening.
- Subject with prior active tuberculosis has no current evidence of active disease and has completed an adequate course of therapy for active tuberculosis (a multi-drug regimen recognized by the World Health Organization) and a chest radiograph is negative for active disease; the chest radiograph must be obtained at screening or, if previously performed and documented, within 3 months prior to screening.
14. Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures. |
