Percentage of Participants With an American College of Rheumatology (ACR) 20 Response at Week 24 [ Time Frame: Baseline and Week 24 ]

A participant was a responder if the following 3 criteria for improvement from Baseline were met:

  • ≥ 20% improvement in tender joint count;
  • ≥ 20% improvement in swollen joint count; and
  • ≥ 20% improvement in at least 3 of the 5 following parameters:

    • Patient's assessment of pain (measured on a 100 mm visual analog scale [VAS]);
    • Patient's global assessment of disease activity (measured on a likert scale from 0 to 10);
    • Physician's global assessment of disease activity (measured on a likert scale from 0 to 10);
    • Patient's self-assessment of physical function (Health Assessment Questionnaire - Disability Index [HAQ-DI]);
    • C-Reactive Protein level.
The primary efficacy endpoint is ACR20 (20% improvement in ACR core set measurements) at week 24. [ Time Frame: Week 24 ]

  • Change From Baseline in Disease Activity Score 28-C-reactive Protein (DAS28-CRP) [ Time Frame: Baseline and weeks 2, 4, 8, 12, 18, and 24 ]

    The DAS28-CRP is a composite score to measure disease activity in patients with rheumatoid arthritis, derived from the following variables:

    • The number of swollen and tender joints assessed using the 28-joint count;
    • C-reactive protein (CRP) level
    • Patient's global assessment of disease activity assessed on a score from 0 to 100 transformed from the result measured on a horizontal scale from 0 (no RA activity at all) to 10 (worst RA activity imaginable).

    The DAS28-CRP score ranges from approximately zero to ten. Higher DAS28-CRP scores indicate higher disease activity.

    A repeated measures analysis with the DAS28-CRP change from baseline as the response and the stratification variables, visit, treatment, treatment-by-visit interaction and the baseline DAS28-CRP measurement as predictors in the model was performed.

  • Percentage of Participants With an ACR20 Response at Week 2 and Week 8 [ Time Frame: Baseline, week 2 and week 8 ]

    A participant was a responder if the following 3 criteria for improvement from Baseline were met:

    • ≥ 20% improvement in tender joint count;
    • ≥ 20% improvement in swollen joint count; and
    • ≥ 20% improvement in at least 3 of the 5 following parameters:

      • Patient's assessment of pain (measured on a 100 mm visual analog scale [VAS]);
      • Patient's global assessment of disease activity (measured on a likert scale from 0 to 10);
      • Physician's global assessment of disease activity (measured on a likert scale from 0 to 10);
      • Patient's self-assessment of physical function (Health Assessment Questionnaire - Disability Index [HAQ-DI]);
      • C-Reactive Protein level.
  • Percentage of Participants With an ACR50 Response at Week 24 [ Time Frame: Baseline and week 24 ]

    A participant was a responder if the following 3 criteria for improvement from Baseline were met:

    • ≥ 50% improvement in tender joint count;
    • ≥ 50% improvement in swollen joint count; and
    • ≥ 50% improvement in at least 3 of the 5 following parameters:

      • Patient's assessment of pain (measured on a 100 mm visual analog scale [VAS]);
      • Patient's global assessment of disease activity (measured on a likert scale from 0 to 10);
      • Physician's global assessment of disease activity (measured on a likert scale from 0 to 10);
      • Patient's self-assessment of physical function (Health Assessment Questionnaire - Disability Index [HAQ-DI]);
      • C-Reactive Protein level.
  • Percentage of Participants With an ACR70 Response at Week 24 [ Time Frame: Baseline and Week 24 ]

    A participant was a responder if the following 3 criteria for improvement from Baseline were met:

    • ≥ 70% improvement in tender joint count;
    • ≥ 70% improvement in swollen joint count; and
    • ≥ 70% improvement in at least 3 of the 5 following parameters:

      • Patient's assessment of pain (measured on a 100 mm visual analog scale [VAS]);
      • Patient's global assessment of disease activity (measured on a likert scale from 0 to 10);
      • Physician's global assessment of disease activity (measured on a likert scale from 0 to 10);
      • Patient's self-assessment of physical function (Health Assessment Questionnaire - Disability Index [HAQ-DI]);
      • C-Reactive Protein level.
  • Number of Participants With Adverse Events [ Time Frame: From the time of first treatment up to 28 days following the last dose of study treatment; 26 weeks. ]

    Adverse events (AEs) were graded for severity according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 according to the following scale:

    1 = mild; 2 = moderate; 3 = severe; 4 = life-threatening; 5 = fatal. A treatment-related AE is defined as an event where the answer to the question "is there a reasonable possibility that the event may have been caused by the Investigational Medicinal Product" was yes.

    A serious adverse event is defined as an AE that meets at least 1 of the following serious criteria:

    • fatal
    • life threatening (places the subject at immediate risk of death)
    • requires inpatient hospitalization or prolongation of existing hospitalization
    • results in persistent or significant disability/incapacity
    • congenital anomaly/birth defect
    • other medically important serious event.
  • Percentage of Participants Who Developed Antibodies to ABP 501 or Adalimumab [ Time Frame: Up to week 26 ]

    Two validated assays were used to detect the presence of anti-drug antibodies. Samples were first tested in an electrochemiluminescence (ECL)-based bridging immunoassay to detect anti-drug antibodies (ADA) against ABP 501 and adalimumab (Binding Antibody Assay). Samples confirmed to be positive for binding antibodies were subsequently tested in a non-cell based bioassay to determine neutralizing activity against ABP 501 or adalimumab (Neutralizing Antibody Assay).

    Developing antibody incidence is defined as a negative or no antibody result at baseline and a positive antibody result at a post-baseline time point.

  • Disease Activity Score 28-CRP [ Time Frame: Week 24 ]
  • ACR50 and ACR70 response [ Time Frame: Week 24 ]
    50% or 70% improvement in ACR core set measurements
  • Incidence of anti-drug antibodies [ Time Frame: Week 26 ]
  • Subject incidence of adverse events and serious adverse events [ Time Frame: Week 26 ]
  • Clinically significant changes in laboratory values and vital signs [ Time Frame: Week 26 ]
  • ACR20 response [ Time Frame: Weeks 2 and 8 ]
    20% improvement in ACR core set measurements
