Brief summary

This was a phase 2 study to evaluate the safety and efficacy of elsubrutinib (ELS) and ABBV-599 (ELS plus upadacitinib \[UPA\]) vs placebo on a background of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) for the treatment of signs and symptoms of rheumatoid arthritis (RA) at 12 weeks in biological disease-modifying anti-rheumatic drugs (bDMARD)-inadequate response (bDMARD-IR) or bDMARD-intolerant participants with moderately to severely active RA and to define optimal dose for further development.

Detailed description

This was a 12-week, randomized, double-blind, parallel-group, Phase 2, dose exploratory, multicenter study. Participants who met eligibility criteria were randomized in a 3:2:2:2:2:1 ratio to 1 of 6 treatment groups: ABBV-599 \[UPA 15 mg/ELS 60 mg\]); ELS 60 mg/UPA placebo; ELS 20 mg/UPA placebo; ELS 5 mg/UPA placebo; UPA 15 mg/ELS placebo; and ELS placebo/UPA placebo. The study included a 35-day maximum screening period and a 12-week treatment period with 30-day follow-up.

MeasureTime frameDescription
Change From Baseline in Disease Activity Score 28 C-reactive Protein [DAS28-CRP]) at Week 12Baseline, Week 12The 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 mm), and high-sensitivity C-reactive protein (hsCRP; in mg/L). Scores on the DAS28-CRP range from 0 to approximately 10, where higher scores indicate more disease activity. A negative change from baseline indicates improvement in disease activity.

Data collected after a participant discontinued study drug was considered as missing. The mixed model included the categorical fixed effects of treatment, visit and treatment-by-visit interaction, prior bDMARD use, and baseline DAS28 (CRP) measurement.p-value: <0.00190% CI: [-2.03, -0.85]t-test, 2 sided

Change From Baseline in Disease Activity Score 28 Erythrocyte Sedimentation Rate (DAS28- ESR)

The DAS28-ESR is a validated index of rheumatoid arthritis disease activity. Twenty-eight tender joint counts, 28 swollen joint counts, the erythrocyte sedimentation rate (ESR; mm/hour), and the participant's assessment of global disease activity (on a visual analog scale \[VAS\] from 0 to 100 mm) are included in the DAS28 -ESR score. Scores on the DAS28-ESR range from 0 to 10; higher scores indicate more disease activity.

Time frame: Baseline, Week 2, Week 4, Week 8, and Week 12

Population: Full Analysis Set: all randomized participants who received at least 1 dose of randomized study drug, had non-missing baseline values, and at least one post-baseline value. Baseline is defined as the last non-missing value prior to the first dose of study drug.

Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI)

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.

Time frame: Baseline, Week 2, Week 4, Week 8, and Week 12

Population: Full Analysis Set: all randomized participants who received at least 1 dose of randomized study drug, had non-missing baseline values, and at least one post-baseline value. Baseline is defined as the last non-missing value prior to the first dose of study drug.

Change From Baseline in Simplified Disease Activity Index (SDAI)

The SDAI is a validated measure of rheumatoid arthritis disease activity. Twenty-eight tender joint counts, 28 swollen joint counts, global disease activity assessed by the participant on a visual analogue scale from 0 to 10 (cm), global disease activity assessed by an investigator on a visual analogue scale from 0 to 10 (cm), and serum levels of C-reactive protein (CRP; mg/dL) were included in the SDAI score. Scores on the SDAI range from 0 to 86.with higher scores indicating higher disease activity. A negative change from baseline indicates improvement in disease activity.

Time frame: Baseline, Week 2, Week 4, Week 8, and Week 12

Population: Full Analysis Set: all randomized participants who received at least 1 dose of randomized study drug, had non-missing baseline values, and at least one post-baseline value. Baseline is defined as the last non-missing value prior to the first dose of study drug.

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 mm), and high-sensitivity C-reactive protein (hsCRP; in mg/L). Scores on the DAS28-CRP range from 0 to approximately 10, where higher scores indicate more disease activity. Clinical remission (CR) based on DAS28 (CRP) is defined as achieving a DAS28 (CRP) of less than 2.6.

Percentage of Participants Achieving Minimal Clinically Important Difference (MCID) in Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI)

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. The minimal clinically important difference (MCID) in HAQ-DI is defined as change from Baseline ≤ -0.22 for rheumatoid arthritis.
