Study of Targeted Therapies for the Treatment of Adult Participants With Active Psoriatic Arthritis

Psoriatic arthritis (PsA) is a type of arthritis that happens when the body's immune system attacks healthy cells and tissues causing joint pain, stiffness, and swelling. Symptoms can get worse and go away for periods of time. This study will evaluate the efficacy and safety of targeted therapies through a series of substudies, for the treatment of active psoriatic arthritis and to assess the changes in disease symptoms.

The therapies being assessed in this sub-study are risankizumab and lutikizumab. Participants will be randomized in a 1:1:1 ratio to one of the three treatment arms: lutikizumab monotherapy, risankizumab monotherapy or a combination therapy of lutikizumab and risankizumab. Around 120 participants will be enrolled in the study at approximately 40 sites worldwide.

There may be higher treatment burden for participants in this trial compared to their standard of care (due to study procedures). Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Participant is willing and able to comply with procedures required in the Master Protocol and substudies.
  • Participant has a documented clinical diagnosis of PsA with symptom onset at least 6 months prior to the Screening Visit and fulfillment of the Classification Criteria for Psoriatic Arthritis (CASPAR) at Screening Visit.
  • Participant has active disease defined as greater than or equal to 3 tender joints (based on 68 joint count) and greater than or equal to 3 swollen joints (based on 66 joint count) at both the Screening Visit and Baseline.
  • Participant has active plaque PsO and/or a documented history of plaque PsO.
  • Participant must demonstrate intolerance or inadequate response to 1 to 2 targeted therapies (biologic or targeted synthetic disease-modifying antirheumatic drugs) approved for the treatment of PsA

Exclusion criteria

  • Participants who have had major surgery performed within 12 weeks prior to randomization or plan to have a major surgery during conduct of the study (e.g., aneurysm removal, stomach ligation).
  • Participants with the following chronic or active infections: Are infected with human immunodeficiency virus (HIV), active hepatitis B virus (HBV) or hepatitis C virus(HCV) infection, active tuberculosis(TB)
  • Active skin disease other than psoriasis (PsO) which could interfere with the assessment of PsO.
  • History of fibromyalgia, any arthritis with onset prior to age 17 years, or current diagnosis of inflammatory joint disease other than psoriatic arthritis (PsA) (including but not limited to rheumatoid arthritis, gout, overlap connective tissue diseases, scleroderma, polymyositis, dermatomyositis, systemic lupus erythematosus).

Primary outcomes

  1. Percentage of Participants With an American College of Rheumatology 50% (ACR50) Response

    Time frame: At Week 16

    Participants who met the following 3 conditions for improvement from Baseline were classified as meeting the ACR50 response criteria:

    • ≥ 50% improvement in 68-tender joint count;
    • ≥ 50% improvement in 66-swollen joint count; and
    • ≥ 50% improvement in at least 3 of the 5 following parameters:
    • Physician global assessment of disease activity
    • Patient global assessment of disease activity
    • Patient assessment of pain
    • Health Assessment Questionnaire - Disability Index (HAQ-DI)
    • High-sensitivity C-reactive protein (hsCRP).

  2. Number of Participants With Adverse Events (AEs)

    Time frame: Up to Week 52

    An AE is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.

Secondary outcomes

  1. Percentage of Participants Achieving Minimal Disease Activity (MDA) Response

    Time frame: At Week 16

    A participant was classified as achieving MDA if 5 of the following 7 criteria were met:

    • Tender joint count (out of 68 joints) ≤ 1
    • Swollen joint count (out of 66 joints) ≤ 1
    • PASI score ≤ 1 (score ranges from 0 - 72) or percent BSA involved with psoriasis ≤ 3%
    • Participant's assessment of pain ≤ 1.5 (NRS from 0 to 10)
    • Participant's Global Assessment of disease activity ≤ 2 (NRS from 0 to 10)
    • HAQ-DI score ≤ 0.5 (index score ranges from 0 to 3)
    • Leeds Enthesitis Index ≤ 1 (assesses the presence or absence of enthesitis at 3 bilateral sites, with an overall score range from 0 to 6)

  2. Percentage of Participants With an American College of Rheumatology 20% (ACR20) Response

    Time frame: At Week 16

    Participants who met the following 3 conditions for improvement from Baseline were classified as meeting the ACR20 response criteria:

    • ≥ 20% improvement in 68-tender joint count;
    • ≥ 20% improvement in 66-swollen joint count; and
    • ≥ 20% improvement in at least 3 of the 5 following parameters:
    • Physician global assessment of disease activity
    • Patient global assessment of disease activity
    • Patient assessment of pain
    • Health Assessment Questionnaire - Disability Index (HAQ-DI)
    • High-sensitivity C-reactive protein (hsCRP).

  3. Percentage of Participants With an American College of Rheumatology 70% (ACR70) Response

    Time frame: At Week 16

    Participants who met the following 3 conditions for improvement from baseline were classified as meeting the ACR70 response criteria:

    • ≥ 70% improvement in 68-tender joint count;
    • ≥ 70% improvement in 66-swollen joint count; and
    • ≥ 70% improvement in at least 3 of the 5 following parameters:
    • Physician global assessment of disease activity
    • Patient global assessment of disease activity
    • Patient assessment of pain
    • Health Assessment Questionnaire - Disability Index (HAQ-DI)
    • High-sensitivity C-reactive protein (hsCRP).

  4. Percentage of Participants Achieving Psoriasis Area Severity Index (PASI) 75 Response (in the subset of participants with a PsO BSA ≥ 3% at Baseline)

    Time frame: At Week 16

    PASI is a composite score based on the percentage of the body surface area (BSA) affected by psoriasis and the intensity of erythema (reddening), induration (thickening or hardening of the skin), and desquamation (peeling of the skin) of lesions assessed at 4 anatomic sites (head, upper extremities, trunk, and lower extremities). At each location, the percentage of BSA involvement is assigned a score from 0 (no involvement) to 6 (90% to 100% involvement), and erythema, induration, and desquamation are scored on a scale from 0 (no symptoms) to 4 (very marked).

    The PASI score ranges from 0 (no psoriasis) to 72 (very severe psoriasis). A PASI-75 response is the percentage of participants who achieved at least a 75% reduction (improvement) from Baseline in PASI score, and was assessed in participants with Baseline psoriasis BSA involvement ≥ 3%.
