Clinical Trial Summary

OPERA aims to better understand and predict the responsiveness of rheumatoid arthrits (RA) patients to biological disease modifying anti-rheumatic drugs (bDMARDs). Our objectives will be (i) to determine, at baseline, the differences of oxylipin response between responders vs non-responders to Anti-Tumor necrosis factor (Anti TNF) and (ii) to investigate the relationships between the oxylipin response, the polyunsatured fatty acid (PUFA) content of immune cells and the cytokine response.

Description:

30 RA patients starting an anti-TNF will be recruited. Before and after 6-months of anti-TNF treatment, blood will be collected using the TruCulture system (2x 1ml in non-stimulated and Lipopolysaccharide (LPS)-stimulated TruCulture tubes) to measure Whole Blood Oxylipin Response (WBOR), cytokine response, PUFA cell content and gene expression under homeostatic and stimulated conditions (i.e. LPS). At baseline and after 6 months of treatment, the rheumatologist will perform a clinical evaluation of their RA patients using Disease Activity Score using 28 joint-count (DAS28-CRP). Non-responders will be defined as RA patients failing to achieve good or moderate EULAR response after 6 month of anti-TNF treatment, discontinued the drug, initiated a new bDMARD, or increased dosage of oral corticosteroids greater than 10 mg/d at the second visit.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Quantification of total oxylipins	Quantitative profiling procedure for oxylipins	Baseline
Secondary	Quantification of polyunsatured fatty acids in blood cells	Quantitative profiling procedure for polyunsatured fatty acids in blood cells (leukocytes, red blood cells and platelets)	Baseline
Secondary	Quantification of cytokines	Large panel of 21 cytokines characteristic of the inflammatory response and lymphocyte polarization. (IL-1ß, IFN-a2, IFN-?, TNF-a, MCP-1 (CCL2), IL-6, IL-8 (CXCL8), IL-10, IL-12p70, IL-17A, IL-18, IL-23, IL-33, IL-5, IL-13, IL-2, IL-9, IL-10, IL-17F, IL-4, IL-22)	Baseline
Secondary	EULAR Response	Non-responders will be defined as rheumatoid arthritis patients failing to achieve good or moderate EULAR response after 6 month of biological disease modifying anti rheumatic drug (bDMARD), discontinued the drug, initiated a new bDMARD, or increased dosage of oral corticosteroids greater than 10 mg/d at the second visit.; EULAR response is determined by the decrease in Disease activity score (DAS) between Baseline and 6 months	6 month
Secondary	Quantification of total oxylipins	Quantitative profiling procedure for oxylipins	6 month
Secondary	Quantification of cytokines		6 month
Secondary	Quantification of polyunsatured fatty acids in blood cells		6 month
