Brief summary

RA is a chronic, systemic inflammatory autoimmune disease which requires treatment for a long time period, hence it is important to study the long-term safety and efficacy of the continuous treatment with GSK3196165 over several years. This is a Phase 3, multicenter, parallel group treatment and long-term extension study primarily to assess safety with efficacy assessment as a secondary objective. Adult participants with RA who have completed the treatment phase of a qualifying GSK3196165 clinical studies (Phase 3 studies contRAst 1 (201790: NCT03980483), contRAst 2 (201791: NCT03970837) and contRAst 3 (202018: NCT04134728) and who, in investigator's judgement will benefit from extended treatment with GSK3196165 will be included in this study (contRAst X \[209564: NCT04333147\]). Participants will continue to receive the same background conventional synthetic disease modifying anti-rheumatic drug(s) \[csDMARD(s)\] treatment as they received in their qualifying study. Eligible participants will be enrolled to receive weekly GSK3196165 90 milligrams (mg) or 150 mg by subcutaneous (SC) injection. The anticipated study duration is approximately 4 years which will enable participants to receive treatment with GSK3196165 until it is expected to become commercially available. Approximately 3000 participants from the qualifying studies will participate in this long-term extension study

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

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

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. CDAI remission is achieved when CDAI total score \<=2.8. Percentage values are rounded off.

Time frame: Week 24, 48, 96 and 144

Population: The analysis was performed on the ITT set that includes all randomized participants who received at least one dose of study treatment. This population was based on the treatment the subject was randomized to. Number of participants analyzed signifies those participants who were evaluable for this outcome measure.
