  5. Patient (or legal guardian, if applicable) is informed of the full nature and purpose of the study, including possible risks and side effects, is able to cooperate with the investigator and is given ample time and opportunity to read and understand verbal and/or written instructions, and signs the written informed consent form with date prior to participation in the study.
  6. Female patient who is considered of childbearing potential (i.e., fertile, following menarche and until becoming post-menopausal unless permanently sterile) must agree to use highly effective methods of contraception consistent with local regulations during the course of the study and at least 20 weeks following discontinuation of study drug (excluding women who are not of childbearing potential). Examples include the following:

    1. Combined (estrogen and progestogen containing) or progestogen-only hormonal contraceptives associated with inhibition of ovulation
    2. Intrauterine device or intrauterine hormone-releasing system
    3. 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), declaration of abstinence for the duration of exposure to investigational drug, and withdrawal are not acceptable methods of contraception.

Male patient who is sexually active with a woman of childbearing potential must agree to use the highly effective method described as above or medically acceptable methods of contraception (e.g., male or female condom AND additional hormonal or barrier method by female partner) consistent with local regulations during the study and for 20 weeks following discontinuation of study drug. If patient or their partner has been surgically sterilized for less than 24 weeks prior to the date of informed consent form (ICF), they also must agree to use method(s) of contraception as described above. Postmenopausal female patients must have experienced their last menses more than 1 year prior to the date of ICF without an alternative medical cause to be classified as not of childbearing potential.

Exclusion Criteria:

    3. Patient who has an indeterminate result for interferon-γ release assay (IGRA) or latent TB (defined as a positive result of IGRA with a negative examination of chest X-ray) at Screening. A patient who has a previous diagnosis of latent TB cannot be enrolled despite sufficient documentation of prophylaxis. If the result of the IGRA is indeterminate at Screening, 1 retest will be possible during the Screening period. If the repeated IGRA result is indeterminate again or positive, the patient will be excluded from the study. If the repeated IGRA result is negative, the patient can be enrolled in the study.
