Mechanistic studies of IL-17 versus TNF blockade in Spondyloarthritis (SpA)


Both TNF and IL-17A are pivotal pathogenic cytokines in SpA. In this project, we hypothesize that blockade of IL-17A and TNF affects different pathophysiological pathways.

We aim to identify specific biological effects by systematic translational comparison of IL-17A versus TNF blockade in SpA patients using combined molecular, cellular and imaging approaches with the overall goal to establish a path towards stratified medicine.

Patient voice

A lay advisory board of patients will be instrumental in the interpretation of the data, in particular in addressing the question if and how the anticipated biologic profiles can be applied in a useful way to stratify individual patients or patient groups to aTNF versus aIL-17A treatment.
