A Study With Upadacitinib (ABT-494) in Subjects From China and Selected Countries With Moderately to Severely Active Rheumatoid Arthritis Who Have Had an Inadequate Response to Conventional Synthetic Disease-Modifying Anti-Rheumatic Drugs (csDMARDs)

The study objectives of Period 1 of this study were to compare the efficacy, safety, and tolerability of upadacitinib versus placebo for the treatment of signs and symptoms of subjects from China and selected countries including Brazil and South Korea with moderately to severely active rheumatoid arthritis (RA) who are on a stable dose of csDMARDs and have an inadequate response to csDMARDs.

The study objective of Period 2 is to evaluate the long-term safety, tolerability, and efficacy of upadacitinib in subjects with RA who have completed Period 1.

About this study

This is a Phase 3 multicenter study that includes two periods. Period 1 is a 12-week, randomized, double-blind, parallel-group, placebo-controlled period designed to compare the safety and efficacy of upadacitinib versus placebo for the treatment of signs and symptoms of participants with moderately to severely active RA who are on a stable dose of csDMARDs and have an inadequate response to csDMARDs. Period 2 is an open label 52 week extension period to evaluate the long-term safety, tolerability, and efficacy of upadacitinib in participants with RA who have completed Period 1.

Who can participate

Primary outcomes

  1. Percentage of Participants With an American College of Rheumatology 20% (ACR20) Response at Week 12

    Time frame: Baseline and Week 12

    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).

Secondary outcomes

  1. Change From Baseline in Disease Activity Score Based on CRP (DAS28 [CRP]) at Week 12

    Time frame: Baseline and Week 12

    The DAS28 (CRP) is a composite index used to assess rheumatoid arthritis disease activity, calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity (0-100), and hsCRP (in mg/L). Scores on the DAS28 range from 0 to 10, where higher scores indicate more disease activity. A negative change from Baseline in DAS28 (CRP) indicates improvement in disease activity.

  2. Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) at Week 12

    Time frame: Baseline and Week 12

    The Health Assessment Questionnaire - Disability Index is a patient-reported questionnaire that measures the degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and errands and chores) over the past week. Participants assessed their ability to do each task on a scale from 0 (without any difficulty) to 3 (unable to do). Scores were averaged to provide an overall score ranging from 0 to 3, where 0 represents no disability and 3 represents very severe, high-dependency disability.

    A negative change from Baseline in the overall score indicates improvement.

  3. Change From Baseline in Short-Form 36 (SF-36) Physical Component Score (PCS) at Week 12

    Time frame: Baseline and Week 12

    The Short Form 36-Item Health Survey (SF-36) Version 2 is a self-administered questionnaire that measures the impact of disease on overall quality of life during the past 4 weeks. The SF-36 consists of 36 questions in eight domains (physical function, pain, general and mental health, vitality, social function, physical and emotional health).

    The physical component score is a weighted combination of the 8 subscales with positive weighting for physical functioning, role-physical, bodily pain, and general health. The PCS was calculated using norm-based scoring so that 50 is the average score and the standard deviation equals 10. Higher scores are associated with better functioning/quality of life; a positive change from baseline score indicates an improvement.

  4. Percentage of Participants Achieving Low Disease Activity (LDA) Based on DAS28 (CRP) at Week 12

    Time frame: Week 12

    Low disease activity based on DAS28 (CRP) is defined a DAS28 (CRP) score of ≤ 3.2.

    The DAS28 is a composite index used to assess rheumatoid arthritis disease activity, calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity (0-100), and hsCRP (in mg/L). Scores on the DAS28 range from 0 to 10, where higher scores indicate more disease activity. A DAS28 score less than or equal to 3.2 indicates low disease activity.

  5. Percentage of Participants Achieving Clinical Remission Based on DAS28 (CRP) at Week 12

    Time frame: Week 12

    Clinical remission (CR) based on DAS28 (CRP) is defined as achieving a DAS28 (CRP) score of less than 2.6.

    DAS28 (CRP) is a composite index used to assess rheumatoid arthritis disease activity, calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity (0-100), and hsCRP (in mg/L). Scores on the DAS28 range from 0 to 10, where higher scores indicate more disease activity.

  6. Percentage of Participants Achieving Low Disease Activity Based on Clinical Disease Activity Index (CDAI) at Week 12

    Time frame: Week 12

    Low disease activity based on CDAI is defined as a CDAI score ≤ 10. CDAI is a composite index for assessing disease activity based on the summation of the total tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), patient global assessment of disease activity measured on a VAS from 0 to 10 cm, and physician global assessment of disease activity measured on a VAS from 0 to 10 cm. The total CDAI score ranges from 0 to 76 with higher scores indicating higher disease activity.

  7. Percentage of Participants With an American College of Rheumatology 50% (ACR50) Response at Week 12

    Time frame: Baseline and Week 12

    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).

  8. Percentage of Participants With an American College of Rheumatology 70% (ACR70) Response at Week 12

    Time frame: Baseline and Week 12

    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).

  9. Percentage of Participants With an American College of Rheumatology 20% (ACR20) Response at Week 1

    • ≥ 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:
