Trial Outcomes & Findings for Mechanistic Study of GSK3196165 Plus Methotrexate (MTX) in Subjects With Active Rheumatoid Arthritis (NCT NCT02799472)

NCT ID: NCT02799472

Last Updated: 2021-01-11

Results Overview

Blood samples were collected for markers which may influence rheumatoid arthritis. Target engagement biomarkers included soluble GM-CSF complexed to GSK3196165. Baseline was defined at Day 1. Change from Baseline was calculated as ratio of Baseline value to post-dose value. Analysis was performed using repeated measures analysis adjusted for GM-CSF - Complex log(Baseline value), treatment group, disease duration (\<=2 or \>2 years), visit and treatment group by visit interaction. Analysis was performed on Intent-to-Treat (ITT) Population which consisted of all participants who were randomized to treatment and who received at least one dose of study treatment. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).

PRIMARY outcome

Timeframe: Baseline and Weeks 1, 4, 12, 12-Week FU (Week 22)

Population: ITT Population.

Whole blood samples were collected and analyzed for markers which may be predictive of rheumatoid arthritis disease activity. Flow cytometry assessment included assessment of CD3+CD8+ and T Cell B Cell NKL. Baseline was defined at Day 1. Change from Baseline was calculated by subtracting the post-dose value from the Baseline value. Analysis was performed using repeated measures analysis adjusted for CD3+CD8+ and T Cell B Cell NKL log(Baseline value), treatment group, disease duration (\<=2 or \>2 years), visit and treatment group by visit interaction. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).

PRIMARY outcome

Timeframe: Baseline and Weeks 1, 4, 12, 12-Week FU (Week 22)

Population: ITT Population.

Whole blood samples were collected and analyzed for markers which may be predictive of rheumatoid arthritis disease activity. Flow cytometry assessment included assessment of CD14-HLA-DR+CD11cbr+CD123-, CD14br+CD16+, CD14br+CD16- and CD14lo+CD16br+. Baseline was defined at Day 1. Change from Baseline was calculated by subtracting the post-dose value from the Baseline value. Analysis was performed using repeated measures analysis adjusted for CD14-HLA-DR+CD11cbr+CD123-, CD14br+CD16+, CD14br+CD16- and CD14lo+CD16br+ (10\^3/Liter) baseline value, treatment group, disease duration (\<=2 or \>2 years), visit and treatment group by visit interaction. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).

Timeframe: Baseline and Weeks 1, 2, 4, 6, 8, 12, 12-Week FU (Week 22)

Population: ITT Population.

Blood samples were collected and analyzed for markers which may be predictive of rheumatoid arthritis disease activity. Mechanistic biomarkers included analysis of Interleukin 1 Beta, Interleukin 10, Interleukin 15, Interleukin 17 Alpha, Interleukin 17F, Interleukin 8 and Tumor Necrosis Factor. Baseline was defined at Day 1. Change from Baseline was calculated as ratio of Baseline value to post-dose value. NA indicates that data is not available since 100% of the data was below limit of quantification at all time points. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).

Immunogenicity samples for determination of anti-drug-antibody (ADA) were collected. The presence of treatment emergent ADA was determined using a GSK3196165 bridging style ADA assay with a bio-analytically determined cut point determined during assay validation. Samples taken after dosing with GSK3196165 that had a value at or above the cut-point was considered potentially treatment-emergent ADA-positive. The immunogenicity population consisted of all participants in the ITT population, who had at least one valid immunogenicity assessment.

For synovitis a total of 8 joints were evaluated. Individual joint scores range from 0-3, where 0= normal, 1=mild, 2=moderate and 3=severe. The final synovitis score is the sum of the individual joint scores. Total score range from 0 (best) to 24 (worst). If an individual location is scored either 'Not Visible' or 'Surgically Modified' then the score for that location was set to missing. Missing joint scores was imputed as the mean of the non-missing joint scores. Baseline was defined at Day 1. Change from Baseline was calculated by subtracting the post-dose value from the Baseline value. Repeated measures analysis adjusted for synovitis score baseline value, treatment group, disease duration (\<=2 or \>2 years), visit and treatment group by visit interaction. Data has been presented for Median and 95% credible interval. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).

For bone erosion a total of 25 locations were evaluated. Individual location scores range from 0-10, where, 0: no erosion; 1: 1-10% of bone eroded and 10: 91-100% of bone eroded. The final bone erosion score is the sum of the individual location scores. The total score ranged from 0 (best) to 250 (worst). If an individual location was scored either 'Not Visible' or 'Surgically Modified' or 'Not Assessable' then the score for that location was set to be missing. Missing joint scores was imputed as the mean of the non-missing location scores. Baseline was defined at Day 1. Change from Baseline was calculated by subtracting the post-dose value from the Baseline value.

RAMRIQ is an automated volume quantification assessment. RAMRIQ assessed same pathologies and joints (except metacarpophalangeal joint \[MCP1\]) as RAMRIS allowing for direct comparison of results obtained using the two methods. Bones were automatically identified in pre-contrast, coronal T1 images using active appearance modelling (AAMs). Joint capsules and soft tissues were also segmented with AAMs, providing consistent 3D regions of interest (ROI) for synovial enhancement across all time points. Synovial volume was calculated as voxels that enhance within each ROI. Baseline was defined at Day 1. Change from Baseline was calculated by subtracting the post-dose value from the Baseline value. Repeated measures analysis adjusted for Synovitis baseline value, treatment group, disease duration (\<=2 or \>2 years), visit and treatment group by visit interaction. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).
