• Have magnetic resonance imaging (MRI)-confirmed PsA axial disease (positive MRI spine and/or sacroiliac [SI] joints, shown by a Spondyloarthritis Research Consortium of Canada [SPARCC] score of >= 3 in either the spine or the sacroiliac joints)
• Have a Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score of at least 4, and have a spinal pain score (on a visual analog scale [VAS]) of at least 4
