A Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of ABBV-3373 in Participants With Moderate to Severe Rheumatoid Arthritis (RA)

Phase 2
Completed
Conditions
Rheumatoid Arthritis (RA)
Interventions
Drug: Placebo for ABBV-3373
Drug: ABBV-3373
Drug: Adalimumab
Drug: Placebo for adalimumab
Registration Number
NCT03823391
Lead Sponsor
AbbVie
Brief Summary

This study will assess the safety, tolerability, and efficacy of ABBV-3373 in participants with moderately to severely active rheumatoid arthritis (RA) on background methotrexate (MTX) compared with adalimumab.

Detailed Description

This study consists of a 12-week double-blind active-controlled phase and a 12 week double-blind extension period.

In the active-controlled period of the first 12 weeks of treatment, participants are randomized to receive either ABBV-3373 100 mg intravenously (IV) every other week (EOW) or adalimumab 80 mg subcutaneously (SC) EOW according to a 2:1 ratio.

At Week 12, the administration of ABBV-3373 was to stop to assess the durability of the observed clinical effects up to 24 weeks. Participants randomized to ABBV-3373 were to receive placebo injections, whereas participants randomized into the adalimumab arm were to continue their 80 mg dosing.

Inclusion Criteria
  • Participant has the clinical diagnosis of RA for > 3 months based on the 1987 American College of Rheumatology (ACR) classification criteria or 2010 ACR/European League against Rheumatism (EULAR) criteria.
  • Participant meets the following disease activity criteria: >= 4 swollen joints (based on 28 joint count) and >= 4 tender joints (based on 28 joint count) at Screening and Baseline visits and disease activity score (28 joints) (DAS28) C-reactive protein (CRP) >= 3.2 at Screening.
  • Participant has an incomplete response to methotrexate. Participants must have been on oral or parental MTX therapy >= 3 months and on a stable prescription of 15 to 25 mg/week (or >= 10 mg/week in participants intolerant of MTX at doses >= 15 mg/week) for >= 4 weeks prior to the first dose of study drug. Participant must be expected to be able to continue on stable dose of MTX for the duration of study participation.

Exclusion Criteria
  • Participants previously exposed to adalimumab or other anti-tumor necrosis factor (TNF) biologics.
  • Participants previously exposed to non-anti-TNF biologics or targeted synthetic disease-modifying antirheumatic drugs (DMARDs) for RA, with exception of participants exposed for less than 3 months and terminated not due to lack of efficacy or intolerability.

Primary Outcome Measures
NameTimeMethod
Change From Baseline to Week 12 in Disease Activity Score (DAS) 28 (C-reactive Protein [CRP])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 (measured on a visual analog scale \[VAS\] from 0-100 mm), and hsCRP (in mg/L). Scores on the DAS28 (CRP) range from 0.96 to approximately 10, where higher scores indicate more disease activity. A negative change from Baseline in DAS28 (CRP) indicates improvement in disease activity.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline to Week 12 in Clinical Disease Activity Index (CDAI)Baseline and Week 12

The clinical disease activity index (CDAI) is a composite index for assessing disease activity based on the summation of the counts of tender joint count (out of 28 evaluated joints) and swollen joint count (out of 28 evaluated joints), Patient Global Assessment of Disease Activity and Physician Global Assessment of Disease Activity both 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. A negative change from Baseline indicates improvement in disease activity.

Change From Baseline in Simplified Disease Activity Index (SDAI)Baseline and Week 12

The SDAI is the numerical sum of five outcome parameters: tender and swollen joint count (based on a 28-joint assessment), Patient Global Assessment of Disease Activity and Physician Global Assessment of Disease Activity both measured on a VAS from 0-10 cm and level of CRP (in mg/dL; normal \< 1 mg/dL). The SDAI has a range from 0 to 86, with higher scores indicating higher disease activity. A negative change from Baseline indicates improvement in disease activity.

Change From Baseline to Week 12 in DAS28 (Erythrocyte Sedimentation Rate [ESR])Baseline and Week 12

The DAS28 (ESR) 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 (measured on a VAS from 0-100 mm), and ESR (in mm/hr). Scores on the DAS28 (ESR) range from 0 to approximately 10, where higher scores indicate more disease activity. A negative change from Baseline indicates improvement in disease activity.

Percentage of Participants Achieving Low Disease Activity (LDA) Based on DAS28 (CRP) at Week 12Week 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 (measured on a VAS from 0-100 mm), and hsCRP (in mg/L). Scores on the DAS28 (CRP) range from 0.96 to approximately 10, where higher scores indicate more disease activity. A DAS28 (CRP) score less than or equal to 3.2 indicates low disease activity.

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

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

1. ≥ 50% improvement in 68-tender joint count;

2. ≥ 50% improvement in 66-swollen joint count; and

3. ≥ 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).
