Magnetic resonance imaging characteristics in patients with spondyloarthritis and clinical diagnosis of heel enthesitis: post hoc analysis from the phase 3 ACHILLES trial
Arthritis Res Ther. 2022 doi: 10.1186/s13075-022-02797-8
Enthesitis is a hallmark feature of SpA, including PsA and axSpA, and is proposed as the primary lesion in spondyloarthropathies. This study aimed to investigate the imaging characteristics of heel enthesitis in SpA in a post hoc analysis using the HEMRIS in blinded and centrally read MRI data from the ACHILLES trial..
Overall, Pathologies were more evident in the Achilles tendon area compared to plantar fascia, with the inflammatory parameters being more responsive with secukinumab treatment compared to placebo.
Patients were randomized to receive subcutaneous secukinumab 150/300 mg or placebo. At week 24, patients on placebo were switched to secukinumab treatment. MRI was performed at three-time points; screening, week 24 and week 52. All MRIs were re-evaluated by 2 blinded central readers in a consensus read fashion for a priori defined MRI parameters based on HEMRIS.
