Individualizing Anti-Inflammatory Medications for Adults With Axial Spondyloarthritis: A Series of N-of 1 Trials

Individualizing Anti-Inflammatory Medications for Adults With Axial Spondyloarthritis: A Series of N-of 1 Trials

The purpose of this study is to compare selective cyclooxygenase-2 (COX-2) and non selective COX inhibitors with respect to the extent to which disease activity is improved without self reported, unacceptable side effects among individual patients with axial spondyloarthritis (AxSpA),to compare selective COX-2 and nonselective COX inhibitors impact on Health related Quality of Life (HrQOL) and how this relates to changes in disease activity and to conduct proteomic assessment of predictive biomarkers of non steroidal anti-inflammatory drug(NSAID) response
