- •Subject has provided signed informed consent including consenting to comply with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol., No known history of active tuberculosis (TB)., Subject has a negative TB test at screening, as defined by1: o Negative QuantiFERON test OR o Subjects with a positive QuantiFERON test are allowed if all of the following is satisfied: * No symptoms of TB as determined by the investigator. * Documented history of adequate prophylaxis initiation prior to receiving study drug per local guidelines. * No known exposure to a case of active TB after most recent prophylaxis. * No evidence of active TB on chest radiograph within 3 months prior to first dose of study drug. o Subjects with an indeterminate QuantiFERON test are permitted to retest once. If the retest result is indeterminate, subject may be randomized if all of the following is satisfied: * No symptoms of TB as determined by the investigator. * Documented history of adequate prophylaxis initiation prior to receiving study drug per local guidelines. * No known exposure to a case of active TB. If subject has previously received TB prophylaxis, no known exposure to active TB after most recent prophylaxis. * No evidence of active TB on chest radiograph within 3 months prior to first dose of study drug. * Deemed to be low risk per risk determination questionnaire and medical monitor review 1 T-SPOT TB test may be used to establish eligibility if agreed upon with the medical monitor., Male and female subjects: Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. a. Male subjects: Male subjects are eligible to participate if they agree to the following during the study drug period and for at least 8 weeks after the last dose of study drug: • Refrain from donating semen, plus either: o Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent. OR o Must agree to use contraception/barrier as detailed below: § Agree to use a male condom (and should also be advised of the benefit for a female partner to use a highly effective method of contraception as a condom may break or leak) when having sexual intercourse with a woman of childbearing potential (WOCBP) who is not currently pregnant. b. Female subjects: A female subject is eligible to participate if she is not pregnant or breastfeeding, and 1 of the following conditions applies: • Is a woman of nonchildbearing potential as defined in Section 10.4 (Contraceptive and Barrier Guidance). OR • Is a WOCBP and uses a contraceptive method that is highly effective, with a failure rate of <1%, as described in Section 10.4 during the study drug period and for at least 8 weeks after the last dose of study drug. The investigator should evaluate the potential for contraceptive method failure (eg, noncompliance, recently initiated) in relationship to the first dose of study drug. A WOCBP must have a negative highly sensitive serum pregnancy test at screening and a negative urine pregnancy test on Day 1 prior to the first dose of study drug, see Section 8.3.5., Subject must be =18 (or the legal age of consent in the jurisdiction in which the study is taking place) and =75 years of age, at the time of signing the informed consent., Clinical diagnosis of PsA with
