Abstract
No app-based nonpharmacological intervention has yet demonstrated to meaningfully improve disease activity, functional status, and disease-specific quality of life in axial spondyloarthritis (axSpA). We evaluated Axia, a CE-marked smartphone application designed for axSpA, that combines personalised exercise therapy, patient education, and disease management, supported by gamification for long-term adherence. To evaluate its clinical efficacy, a 12-week monocentric randomised controlled interventional trial was conducted involving 200 patients with axSpA with stable pharmacotherapy. Patients were randomised (1:1) to either using Axia (intervention group [IG]) or standard of care (control group [CG]). A total of 186 participants (mean age 50.61 years, 66% females, 56% with radiographic axSpA, mean Bath Ankylosing Spondylitis Disease Activity Index [BASDAI] 5.17, and 58% received biologicals or Janus kinase inhibitors) completed the study (95 in the IG and 91 in the CG). Compared to CG, participants in the IG demonstrated significant improvements in BASDAI (analysis of covariance [ANCOVA]-estimated group difference: -1.508, P < .001), Bath Ankylosing Spondylitis Functional Index (-1.139; P < .001), and Ankylosing Spondylitis Quality of Life questionnaire (-2.297; P < .001), all exceeding minimal clinically important difference thresholds. A significantly higher proportion of patients in the IG achieved an Assessment of Spondyloarthritis International Society (ASAS)20 response compared to the CG (51% vs 9%; P < .001), and the ASAS40 response rate was also higher (23% vs 3%; P < .001). No concerning safety signals were observed. These findings support the potential of Axia as a safe and effective nonpharmacological intervention to further improve the state of care of patients with axSpA in addition to conventional anti-inflammatory pharmacotherapy.
