Assessing IL-17 levels in patients with spondyloarthritis

Feasibility of an Il-17a Assay and Impact on Therapeutic Response in Patients With Active Axial Spondyloarthritis

Observational Centre Hospitalier Universitaire de Nice · NCT05592574

This study is testing if measuring IL-17 levels in patients with active spondyloarthritis can help doctors choose the best biological treatment after other medications haven't worked.

What this trial studies

This observational study aims to evaluate the feasibility of measuring IL-17 cytokine levels in patients with active spondyloarthritis (axSpA) who require biological treatment after failing at least two non-steroidal anti-inflammatory drugs (NSAIDs). By stimulating immune cells and analyzing cytokine responses, the study seeks to develop a tool that could assist clinicians in selecting the most appropriate biologic therapy for these patients. The study focuses on patients meeting the ASAS criteria for spondyloarthritis and aims to address the lack of validated biomarkers in this area.

Who should consider this trial

Good fit: Ideal candidates for this study are patients with active spondyloarthritis who have not responded to at least two NSAIDs and meet the ASAS criteria.

Not a fit: Patients with predominant axial manifestations or those who have previously received biological treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a valuable tool for clinicians to make more informed decisions regarding biologic treatments for patients with spondyloarthritis.

How similar studies have performed: While there have been head-to-head studies comparing biologics in related conditions, this specific approach to cytokine measurement in spondyloarthritis is novel and has not been extensively tested.
