Protocol ID

Brief summary


This is a Phase 3 multicenter study that includes two periods. Period 1 is designed to compare the safety, tolerability, and efficacy of ABT-494 Dose A once daily (QD) and Dose B QD versus placebo in participants with moderately to severely active Psoriatic Arthritis (PsA) who have an inadequate response to Biological Disease Modifying Anti-Rheumatic Drug (bDMARDs). Period 2 evaluates the safety, tolerability and efficacy of ABT-494 Dose A QD and Dose B QD in subjects with PsA who have completed Period 1.

Participant Attributes :
  • Male and Female
  • Ages 18 Years to 99 Years

Study Design

  • The method used to assign participants to an arm of a clinical trial, for example Randomized (assigned by chance) versus Non-randomized.



  • A target outcome that the study’s protocol aims to evaluate - things like: the occurrence of a disease, a symptom, sign, or lab abnormality, among others.

    Endpoint Classification

    Field no longer in system

  • The general design that shows how the medical interventions will be assigned to the participants, e.g., whether all patients will receive the same drug, or if different groups receive two or more different treatments in a particular order.

    Intervention Model

    Parallel Assignment

  • The general design that describes the strategy for identifying and following up with participants during observational studies.


    Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)

  • This is the single main reason for carrying out the clinical trial. Reasons can include: treatment, prevention, diagnostic advances, supportive care, screening, or health services research, among others.



    • Clinical diagnosis of PsA with symptom onset at least 6 months prior to the Screening Visit and fulfillment of the Classification Criteria for PsA (CASPAR) criteria
    • Participant has active disease at Baseline defined as >= 3 tender joints (based on 68 joint counts) and >= 3 swollen joints (based on 66 joint counts) at Screening and Baseline Visits
    • Diagnosis of active plaque psoriasis or documented history of plaque psoriasis
    • Participant has had an inadequate response (lack of efficacy after a minimum 12 week duration of therapy) or intolerance to treatment with at least 1 bDMARD.
    • Prior exposure to any Janus Kinase (JAK) inhibitor (including but not limited to ruxolitinib, tofacitinib, baricitinib, and filgotinib)
    • Current treatment with > 2 non-biologic DMARDs or use of DMARDs other than Methotrexate (MTX), Sulfasalazine (SSZ), Leflunomide (LEF), apremilast, Hydroxychloroquine (HCQ), bucillamine or iguratimod or use of MTX in combination with LEF at Baseline.
    • History of fibromyalgia, any arthritis with onset prior to age 17 years, or current diagnosis of inflammatory joint disease other than PsA (including, but not limited to rheumatoid arthritis, gout, overlap connective tissue diseases, scleroderma, polymyositis, dermatomyositis, systemic lupus erythematosus). Prior history of reactive arthritis or axial spondyloarthritis including ankylosing spondylitis and non-radiographic axial spondyloarthritis is permitted if documentation of change in diagnosis to PsA or additional diagnosis of PsA is made. Prior history of fibromyalgia is permitted if documentation of change in diagnosis to PsA or documentation that the diagnosis of fibromyalgia was made incorrectly.
