Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43851   clinical trials with a EudraCT protocol, of which   7283   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    End point description
    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).

    		 Change from Baseline in Predictive Biomarkers: Amyloid A
    End point description
    Blood samples were collected and analyzed for markers which may be predictive of rheumatoid arthritis disease activity. Predictive biomarkers included analysis of Amyloid A. 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 Amyloid A 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). Data has been presented for only those time points at which the samples were collected.

    		 Change from Baseline in Predictive Biomarkers: Chitinase 3 Like 1, Matrix Metalloproteinase 3 (MMP-3)
    End point description
    Blood samples were collected and analyzed for markers which may be predictive of rheumatoid arthritis disease activity. Predictive biomarkers included analysis of Chitinase 3 Like 1 and MMP-3. 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 Chitinase 3 Like 1 and MMP-3 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).

    		 Change from Baseline in Cartilage Biomarkers
    End point description
    Blood samples were collected and analyzed for markers that may be predictive of rheumatoid arthritis disease activity. Cartilage biomarkers included analysis of ARGS Neo-Epitope, Citrullinated MMP-Degraded Vimentin (CMDV), MMP-Degraded C Reactive Protein (CRP), MMP-Degraded Type I Collagen (MD1C), MMP-Degraded Type II Collagen (MD2C), MMP-Degraded Type III Collagen (MD3C). 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 ARGS Neo-Epitope, Citrullinated MMP-Degraded Vimentin, MMP-Degraded CRP, MMP-Degraded Type I Collagen, MMP-Degraded Type II Collagen and MMP-Degraded Type III Collagen 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).

    		 Change from Baseline in Flow Cytometry: Helper/Suppressor cells
    End point description
    Whole blood samples were collected and analyzed for markers which may be predictive of rheumatoid arthritis disease activity. Flow cytometry assessment included assessment of Helper/Suppressor. 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 Helper/Suppressor 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).

    		 Change from Baseline in Flow Cytometry: 6 Colour TBNK Panel- CD3+CD8+ and T Cell B Cell Natural Killer Lymphocytes (NKL)
    End point description
    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).

    		 Change from Baseline in T Helper Cell Panel events
    End point description
    Blood samples were collected and analyzed for markers which may be predictive of rheumatoid arthritis disease activity. T Helper Cell Panel included analysis of CD45+3+8-4+CCR6+CXCR3+38+DR+, CD45+3+8-4+CCR6+CXCR3-38+DR+, CD45+3+8-4+CCR6-CXCR3+38+DR+, CD45+3+8-4+CCR6-CXCR3-38+DR+, CD45+CD3+CD8-CD4+, CD45+CD3+CD8-CD4+CCR6+CXCR3+, CD45+CD3+CD8-CD4+CCR6+CXCR3-, CD45+CD3+CD8-CD4+CCR6-CXCR3+ and CD45+CD3+CD8-CD4+CCR6-CXCR3-. 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 T Helper Cell Panel Events (EVENTS) 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).

    		 Change from Baseline in Flow Cytometry: CD16+ Monocyte Panel: CD14-HLA-DR+CD11cbr+CD123-, CD14br+CD16+, CD14br+CD16-, CD14lo+CD16br+
    End point description
    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).

    		 Change from Baseline in Flow Cytometry: CD16+ Monocyte Panel: CD14-CD16+CD66b+
    End point description
    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-CD16+CD66b+ cell. 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-CD16+CD66b+ (10^6/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).

    		 Change from Baseline in Mechanistic Biomarkers [35]
    End point description
    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. 99999 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.

    		 Change from Baseline in synovitis as assessed by Outcome Measures in Rheumatology (OMERACT) rheumatoid arthritis magnetic resonance imaging scoring system (RAMRIS) in the most affected hand/wrist
    End point description
    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).

    		 Change from Baseline in osteitis as assessed by OMERACT RAMRI scoring system in the most affected hand/wrist
    End point description
    For bone edema/osteitis a total of 25 locations was evaluated. Individual location scores ranged from 0-3, where, 0: no edema; 1: 1–33% of bone edematous; 2: 34–66% of bone edematous; 3: 67–100% of bone edematous. Final bone edema/osteitis score is sum of individual location scores. Total score ranged from 0 (best) to 75 (worst). Baseline was defined at Day 1. Change from Baseline was calculated by subtracting post-dose value from Baseline value. 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 mean of non-missing location scores. Repeated measures analysis adjusted for Bone Edema/Osteitis Score 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).

    End point description
    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 >2years), 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).

Bones were automatically identified in pre-contrast, coronal T1 images using AAMs. Joint capsules and soft tissues were also segmented with AAMs, providing consistent 3D ROI for synovial enhancement across all time points. Erosion volume was identified inside the bone surfaces using voxel-based classification. The volume of BME and erosions was normalised to total bone volume for statistical analysis. Baseline was defined at Day 1. Change from Baseline was calculated by subtracting the post-dose value from the Baseline value.
