10. Subjects taking csDMARDs, with the exception of MTX, cyclosporine, or LEF (see Section 4.4, Exclusion Criterion 18, 19 and 20), do not require a washout period. However, they must discontinue the csDMARD treatment at least one day prior to their Baseline Visit (ie, Visit 2, Day 1)
11. Subjects who have been previously treated with MTX for < 6 months and who are not on stable doses for at least 3 months will require a 28-day washout prior to the Baseline Visit (ie, Visit 2, Day 1) to participate in the study
12. Subjects who have been previously treated with LEF will require a 12-week washout prior to the Baseline Visit (ie, Visit 2, Day 1), or treatment with cholestyramine, per LEF
prescribing label (ie, 8 g cholestyramine 3 times daily for 11 days)
13. Subjects who have been previously treated with cyclosporine will require a 28-day washout prior to the Baseline Visit (ie, Visit 2, Day 1) to participate in the study
14. If taking MTX (≤ 25 mg/week), continuity of treatment will be allowed if duration of treatment is ≥ 6 months and on a stable dose for at least 3 months prior to the Baseline Visit (ie, Visit 2, Day 1)
15. If taking oral glucocorticoids, must be on a stable dose of prednisone ≤ 10 mg/day or equivalent for at least 4 weeks prior to the Baseline Visit (ie, Visit 2, Day 1)
16. If taking NSAIDs or narcotic analgesics, must be on stable dose for at least 4 weeks prior to Baseline Visit (ie, Visit 2, Day 1)
17. A female of childbearing potential (FCBP)† must have a negative pregnancy test at screening and baseline. While on IP and for at least 28 days after taking the last dose of IP, a FCBP who engages in activity in which conception is possible must use one of the approved
contraceptive§ options described below:
Option 1: Any one of the following highly effective methods: hormonal contraception (oral, injection, implant, transdermal patch, vaginal ring); intrauterine device; tubal ligation; or partner’s vasectomy;
OR
Option 2: Male or female condom (latex condom or non-latex condom NOT made out of natural [animal] membrane [for example, polyurethane]); PLUS one additional barrier
method: (a) diaphragm with spermicide; (b) cervical cap with spermicide; or (c) contraceptive sponge with spermicide.
Note: Option 2 may not be acceptable as a highly effective contraception
option in all countries, per local guidelines/recommendations.
† An FCBP is defined as a sexually mature female who 1) has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries) or 2) has not been postmenopausal for at least 24 consecutive months (that is, has had menses at any time during the preceding 24
consecutive months).
§ The female subject’s chosen form of contraception must be effective by the time the female subject is screened into the study (for example, hormonal contraception should be initiated at least 28 days before screening).
18. Must be in general good health (except for PsA) as judged by the investigator, based on medical history, physical examination, and clinical laboratories. (Note: The definition of good health means a subject does not have uncontrolled significant comorbid conditions). |
