Reduction of CXCR3 + CCR6 + CD4 + T Cells and IL ‐17+ RORγt + CD4 + T Cells During Secukinumab Treatment Identifies Patients With Axial Spondyloarthritis Responsive to Subsequent Biologic Therapy
Objective We recently reported an immune profile that stratifies patients with axial spondyloarthritis based on clinical response to secukinumab. We now undertake an exploratory study on the secukinumab nonresponder patients to determine if immunologic changes occur during their initial secukinumab treatment that could determine their next biologic response. Methods At the clinician's discretion, 18 patients who did not respond to secukinumab were either switched to a tumor necrosis factor inhibitor (TNFi; n = 8) o …
