A Study to Compare Upadacitinib (ABT-494) Monotherapy to Methotrexate (MTX) Monotherapy in Adults With Rheumatoid Arthritis (RA) Who Have Not Previously Taken Methotrexate

The objectives of Period 1 were the following:

* To compare the safety and efficacy of upadacitinib 7.5 mg once daily (QD) monotherapy (for participants in Japan only), 15 mg QD monotherapy, and 30 mg QD monotherapy versus weekly methotrexate monotherapy for the treatment of signs and symptoms of RA in methotrexate-naïve adults with moderately to severely active RA; * To compare the efficacy of upadacitinib 15 mg QD monotherapy and upadacitinib 30 mg QD monotherapy versus weekly methotrexate monotherapy for prevention of structural progression in methotrexate-naïve adults with moderately to severely active RA.

The objective of Period 2 is to evaluate the long-term safety, tolerability, and efficacy of upadacitinib 7.5 mg QD (for participants in Japan only), 15 mg QD, and 30 mg QD in adults with RA who have completed Period 1.

About this study

This study includes 2 periods (a 48-week double-blind treatment period and a long-term extension period) and a Japan substudy. In Period 1 participants will be randomized in a 1:1:1 ratio to treatment Groups 2, 3, and 4 below, except for participants from Japan, who will be randomized in a 2:1:1:1 ratio to Groups 1, 2, 3, and 4:

  • Group 1: Upadacitinib 7.5 mg once daily (QD) monotherapy (participants in Japan only)
  • Group 2: Upadacitinib 15 mg QD monotherapy
  • Group 3: Upadacitinib 30 mg QD monotherapy
  • Group 4: Methotrexate monotherapy

Rescue therapy is defined for Weeks 12 through 24, Week 26, and Weeks 36 through 40. Starting at Week 12 through Week 24, participants who do not achieve ≥ 20% improvement in both tender joint count (TJC) and swollen joint count (SJC) compared with baseline at two consecutive visits will continue on their blinded therapy and the Investigator should optimize (initiate or increase) background RA medications: non-steroidal anti-inflammatory drug(s) (NSAIDs), corticosteroids (oral ≤ 10 mg/day prednisone equivalent or prednisone equivalent ≤ 0.5 mg/kg/day for 3 consecutive days) and/or low-potency analgesics.

Rescue therapy for participants who meet the following criteria at Week 26 are as follows:

Participants who do not achieve clinical remission (CR) based on Clinical Disease Activity Index (CDAI) (defined as a CDAI score ≤ 2.8):

  • but achieve ≥ 20% improvement in both TJC and SJC compared with baseline will continue on blinded study drug and the Investigator should optimize (initiate or increase) background RA medications: NSAIDs, corticosteroids (oral ≤ 10 mg/day prednisone equivalent and up to 2 local injections), low-potency analgesics and conventional synthetic disease-modifying anti-rheumatic drug(s) (csDMARDs) (only 1 of the following: sulfasalazine, hydroxychloroquine or chloroquine) throughout the remainder of Period 1 and until the study is unblinded.
  • and do not achieve ≥ 20% improvement in both TJC and SJC compared with baseline and originally assigned to methotrexate will be re-randomized in a 1:1 ratio to receive blinded upadacitinib 15 mg QD or upadacitinib 30 mg QD (participants in Japan will be randomized 1:1:1 to receive upadacitinib 7.5 mg QD, 15 mg QD, or 30 mg QD) while continuing methotrexate treatment in a blinded manner until the study is unblinded. Participants originally assigned to upadacitinib will add methotrexate 10 mg/week (7.5 mg for Japan) to upadacitinib in a blinded manner and will remain on upadacitinib plus methotrexate 10 mg/week (7.5 mg for Japan) until the study is unblinded.

Starting at Week 36 through Week 40, participants who do not achieve ≥ 20% improvement in both TJC and SJC compared with baseline at two consecutive visits will continue on their blinded therapy and the Investigator should optimize (initiate or increase) background RA medications: NSAIDs, corticosteroids (oral ≤ 10 mg/day prednisone equivalent or prednisone equivalent ≤ 0.5 mg/kg/day for 3 consecutive days and up to 2 local injections), low-potency analgesics and csDMARDs (only 1 of the following: sulfasalazine, hydroxychloroquine or chloroquine).

Participants who complete the Week 48 visit (end of Period 1) will enter the long-term extension, Period 2 (212 weeks) and continue study treatment per assignment at the end of Period 1 in a blinded fashion. When the last participant completes the last visit of Period 1 (Week 48), study drug assignment in both periods may be unblinded, and participants will be dispensed study drug in an open-label fashion until the completion of Period 2. Starting with Protocol Amendment 6, participants receiving upadacitinib 15 mg and 30 mg QD will receive open-label upadacitinib 15 mg QD, and participants receiving methotrexate will receive open-label methotrexate.

A global analysis will be conducted for the comparisons of the primary and secondary efficacy endpoints between the upadacitinib 15 mg QD and 30 mg QD treatment groups versus the methotrexate treatment group for all participants (excluding the Japan specific upadacitinib 7.5 mg treatment group). Analyses will be conducted separately for United States (US)/Food and Drug Administration (FDA), European Union (EU)/European Medicines Agency (EMA), and Japan/Pharmaceuticals and Medical Devices Agency (PMDA) regulatory purposes, each according to a pre-specified sequence of primary and ranked secondary endpoints.

A separate Japan sub-study analysis will be conducted for the comparisons of the efficacy endpoints between the upadacitinib 7.5 mg QD, 15 mg QD, and 30 mg QD treatment groups versus the methotrexate treatment group for participants enrolled in Japan only.

    The primary endpoint for European Union (EU)/European Medicines Agency (EMA) regulatory purposes was clinical remission, based on a Disease Activity Score 28 (DAS28)-CRP score of < 2.6 at Week 24.

    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 mm), and hsCRP (in mg/L). Scores on the DAS28 range from 0 to approximately 10, where higher scores indicate more disease activity.

    A DAS28 score less than 2.6 indicates clinical remission.

  3. Percentage of Participants With an American College of Rheumatology 20% (ACR20) Response at Week 12 - Global Analysis

    Time frame: Baseline and Week 12

    The primary endpoint for Japan/Pharmaceuticals and Medical Devices Agency (PMDA) regulatory purposes was ACR 20% response (ACR20) at 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;

    The second primary endpoint for Japan/PMDA regulatory purposes was change from baseline in mTSS at Week 24.

    The mTSS measures the level of joint damage from radiographs of the hands and feet. Joint erosion and joint space narrowing (JSN) were assessed by two independent, blinded readers.

    Joint erosion was assessed in 16 joints in each hand/wrist and 6 joints in each foot. Each joint was scored from 0 (no erosion) to 5 for hands/wrists or to 10 for feet (complete collapse). The total erosion score ranges from 0 to 280 (worst).

    JSN was assessed in 15 joints of each hand and wrist, and 6 joints of each foot, including subluxation, from 0 (normal) to 4 (complete loss of joint space, bony ankylosis, or luxation). The total JSN score ranges from 0 to 168 (worst).

    The mTSS is the sum of the joint erosion and JSN scores and ranges from 0 (normal) to 448 (worst). A change from Baseline greater than 0 indicates progression.

Secondary outcomes

  1. Change From Baseline in DAS28 (CRP) at Week 12 - Global Analysis

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.

    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.

  5. Change From Baseline in DAS28 (CRP) at Week 24 - Global Analysis
