E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Moderate to Severe Rheumatoid Arthritis |
|
E.1.1.1 | Medical condition in easily understood language |
The body's immune system attacks the joints, creating inflammation that cause the synovium to thicken. Resulting in swelling and pain in and around the joints. This can cause permanent joint damage. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To assess the safety, tolerability, and efficacy of ABBV-3373 administered every other week (eow) intravenously (IV) in subjects with moderately to severely active RA on background MTX. 2. To compare clinical efficacy of ABBV-3373 with adalimumab and to test the concept that an anti-TNF antibody-drug-conjugate has the potential to provide superior efficacy than the traditional anti-TNF antibody in RA. |
|
E.2.2 | Secondary objectives of the trial |
3. To compare adalimumab with synthetic control to establish assay sensitivity. 4. To assess the pharmacokinetics (PK), pharmacodynamics and immunogenicity of ABBV-3373. 5. To assess the durability of the treatment effect of ABBV-3373 after discontinuation.

|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Adult male or female, between 18 and 75 years of age inclusive at Screening. 2. Subject has the clinical diagnosis of RA for > 3 months based on the 1987 ACR classification criteria or 2010 ACR/European League against Rheumatism (EULAR) criteria. 3. Subject 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 BL Visits; and DAS28(CRP) ≥ 3.2 at Screening. 4. Subject has an incomplete response to MTX. Subjects must have been on oral or parenteral MTX therapy ≥ 3 months and on a stable prescription of 15 to 25 mg/week (or ≥ 10 mg/week in subjects intolerant of MTX at doses ≥ 15 mg/week) for ≥ 4 weeks prior to the first dose of study drug. Subject must be expected to be able to continue on stable dose of MTX for the duration of study participation. |
|
E.4 | Principal exclusion criteria |
1. Subjects previously exposed to adalimumab or other anti-TNF biologics. 2. Subjects previously exposed to non-anti-TNF biologics or targeted synthetic DMARDs for RA, with exception of subjects exposed for less than 3 months and terminated not due to lack of efficacy or intolerability. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
The change in disease activity score (DAS)28 (C-reactive protein [CRP]) from Baseline (BL) at Week 12 for ABBV-3373 and adalimumab. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
1. Change in clinical disease activity index (CDAI) from BL at Week 12 for ABBV-3373 and adalimumab. 2. Change in simplified disease activity index (SDAI) from BL at Week 12 for ABBV-3373 and adalimumab. 3. Change in DAS28 erythrocyte sedimentation rate [ESR] from BL at Week 12 for ABBV-3373 and adalimumab. 4. Proportion of subjects achieving a low disease activity (LDA) (DAS28 [CRP] ≤3.2) at Week 12 for ABBV-3373 and adalimumab. 5. Proportion of subjects achieving American College of Rheumatology (ACR) 50 at Week 12 for ABBV-3373 and adalimumab. |
