a. At least 1 confirmed lesion of plaque psoriasis of at least 2 cm,
b. Nail changes attributed to psoriasis.
7. Active PsA as defined by = 3 swollen joints (SJC66) and = 3 tender joints (TJC68) at Screening and Day 1; these need not be the same joints at Screening and Day 1.
8. Demonstrated inadequate response to, loss of response to, or intolerance to at least one of the following therapies:
a. Conventional nonbiologic DMARDs (eg, methotrexate, leflunomide, sulfasalazine, or hydroxychloroquine), or apremilast,
b. NSAIDs,
c. Corticosteroids.
9. Participant either (i) did not have prior exposure to biologics (biologic-naïve) or (ii) have failed or been intolerant to 1 TNFi or 1 IL-17 inhibitor. Failure is defined as lack of response or loss of response with = 12 weeks of therapy with an approved dose of a TNFi or IL-17 inhibitor, as judged by the investigator. Failure must have occurred = 8 weeks prior to Day 1 for TNFi and = 12 weeks prior to Day 1 for an IL-17 inhibitors.
10. Participants are permitted to receive the following medications if doses and frequency are stable for = 2 weeks prior to Day 1 and they agree to continue using them at the same dosage during the study:
a. NSAIDs if dose is consistent with labeling recommendations for pain,
b. Acetaminophen (= 4 g/day)/paracetamol,
c. Oral corticosteroids (= 10 mg/day prednisone equivalent),
d. Concurrent topical therapy for plaque psoriasis.
11. If on a conventional nonbiologic DMARD (eg, methotrexate, sulfasalazine, hydroxychloroquine, leflunomide; excludes apremilast), participants can continue using 1 DMARD provided it has been used for = 12 weeks prior to Day 1 with a stable dose and frequency for = 4 weeks prior to Day 1, at the same dosage during the study.
12. Women must meet either (a) or (b) of the following criteria and men must meet criterion (c) to qualify for the study:
a. A woman who is not of childbearing potential must meet 1 of the following:
•i. Postmenopausal, defined as no menses for 12 months without an alternative medical cause, and an FSH test with a result = 30 mIU/mL, confirming nonchildbearing potential.
•ii. Permanent sterilization procedure, such as hysterectomy, bilateral salpingectomy, or bilateral oophorectomy.
b. A nonpregnant woman of childbearing potential must agree to use a highly effective contraception method that can achieve a failure rate of less than 1% per year when used consistently and correctly. The highly effective contraception must be used through the duration of the study and for 30 days after the last dose of study product. The following are considered highly effective birth control methods:
•Combined (estrogen- and progesterone-containing) hormonal contraception associated with inhibition of ovulation, which may be oral, intravaginal, or transdermal,
•Progesterone-only hormonal contraception associated with inhibition of ovulation, which may be oral, injected, or implanted,
•Intrauterine device,
•Intrauterine hormone-releasing sy
