Efficacy and Safety of GSK3196165 Versus Placebo and Tofacitinib in Participants With Moderately to Severely Active Rheumatoid Arthritis Who Have an Inadequate Response to Methotrexate

Study Overview
=================
Brief Summary
-----------------
This study [contRAst 1 (201790: NCT03980483)] is a phase 3, randomized, multicenter, double blind study to assess the safety and efficacy of GSK3196165, in combination with methotrexate (MTX), for the treatment of adult participants with moderate to severe active rheumatoid arthritis (RA) who have had an inadequate response to MTX. The study will consist of a screening phase of up to 6 weeks followed by a 52-week treatment phase in which participants will be randomized in a ratio of 6:6:3:1:1:1 to receive GSK3196165 150 milligrams (mg) subcutaneous (SC) weekly, GSK3196165 90 mg SC weekly, tofacitinib capsules (cap) 5 mg twice a day or placebo (three arms, each placebo arm will have 12 weeks placebo followed by 40 weeks active treatment) respectively, all in combination with MTX. Participants who, in investigator's judgement will benefit from extended treatment with GSK3196165, may be included in the long-term extension study [contRAst X (209564: NCT04333147)]. For those participants who do not continue into the long term-extension study, there will be an 8 week safety follow-up visit following the treatment phase.

Eligibility Criteria
-----------------
Key inclusion criteria >=18 years of age Has had RA for >=6 months and was not diagnosed before 16 years of age Has active disease, as defined by having both:* >=6/68 tender/painful joint count (TJC), and >=6/66 swollen joint count (SJC) Has at least 1 bone erosion present on hand/wrist or foot radiographs Has had an inadequate response to MTX, despite currently taking MTX 15-25 mg/week** oral or injected If surgical treatment of a joint has been performed, that joint cannot be counted in the TJC or SJC.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Achieving 20 Percentage (%) Improvement in American College of Rheumatology Criteria (ACR20) at Week 12 Superiority Comparison With Placebo | ACR20 is calculated as a 20% improvement from Baseline in Tender Joint Count 68 (TJC68) and Swollen Joint Count 66 (SJC66) and a 20% improvement in 3 of the following 5 measures: Patient's Global Assessment of Arthritis Disease Activity (PtGA) [visual analogue scale (VAS) with values from 0=best to 100=worst], Physician Global Assessment of Arthritis Disease Activity (PhGA) (VAS with values from 0=best to 100=worst), Patient Assessment of Arthritis Pain (VAS with values from 0=no pain and 100=most severe pain), Health Assessment Questionnaire-Disability Index (HAQ-DI) (ranges from 0 to 3 where 0 = least difficulty and 3 = extreme difficulty) and an acute-phase reactant [high sensitivity C-reactive Protein milligram per liter (mg/L) (hsCRP)]. For the purpose of all analyses up to week 12, the placebo arms were pooled into a single placebo arm to primarily serve as a reference for the comparison of active treatment arms. | Week 12 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Achieving Clinical Disease Activity Index (CDAI) Total Score Less Than or Equal to (<=)10 [CDAI Low Disease Activity (LDA)] at Week 12 | Clinical Disease Activity Index (CDAI) total score is a composite score consisting of the sum of Swollen Joint Count 28 (SJC28), Tender Joint Count 28 (TJC28), Patient's Global Assessment of Arthritis Disease Activity (PtGA) (visual analogue scale with values from 0=best to 100=worst) and Physician Global Assessment of Arthritis Disease Activity (PhGA) (visual analogue scale with values from 0=best to 100=worst). PtGA and PhGA are transformed to a 0-10 scale before computing the CDAI total score. CDAI total score ranges from 0 to 76 with higher values representing higher disease activity. Low disease activity (LDA) is achieved when CDAI total score <=10. For the purpose of all analyses up to week 12, the placebo arms were pooled into a single placebo arm to primarily serve as a reference for the comparison of active treatment arms. | Week 12 | 
| Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) at Week 12 | Health Assessment Questionnaire-Disability Index (HAQ-DI) is a 20-question instrument that assesses degree of difficulty of a participant in accomplishing tasks in eight functional areas: dressing and grooming, arising, eating, walking, hygiene, reach, grip and common daily activities. Overall HAQ-DI score was computed as sum of the domain scores divided by the number of domains answered. The total possible score ranges from 0 to 3 where 0=least difficulty and 3=extreme difficulty. Higher overall score indicates greater disability. A negative change from baseline indicates an improvement. Baseline was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Change from Baseline was calculated by subtracting the post dose visit value from the Baseline value.

| Number of Participants With Anti-GSK3196165 Antibodies | Serum samples were collected for the determination of anti- GSK3196165 antibodies (ADA) using a validated electrochemiluminescence (ECL) immunoassay. The assay involved screening, confirmation and titration steps. If serum samples tested positive in the screening assay, they were considered 'potentially positive' and were further analyzed for the specificity using the confirmation assay. Samples that confirmed positive in the confirmation assay were reported as 'positive'. Confirmed positive ADA samples were further characterized in the titration assay to quasi-quantitate the amount of ADA in the sample. Additionally, confirmed positive ADA samples were also tested in a validated neutralizing antibody assay to determine the potential neutralizing activity of the ADA. | Up to Week 59 |
