ANKYLOSING SPONDYLITIS, INFLAMMATION, NR-AXSPA, BONE MARROW EDEMA, SACROILIITIS
In the PREVENT study, adult patients fulfilling the Assessment of SpondyloArthritis International Society classification criteria for nr-axSpA with elevated CRP and/or MRI inflammation received secukinumab 150 mg or placebo. All patients received open-label secukinumab from week 52 onward. Sacroiliac (SI) joint and spinal radiographs were scored using the modified New York (mNY) grading (total sacroiliitis score; range, 0–8) and modified Stoke Ankylosing Spondylitis Spine Score (mSASSS; range, 0–72), respectively. SI joint bone marrow edema (BME) was assessed using the Berlin Active Inflammatory Lesions Scoring (0–24) and spinal MRI using the Berlin modification of the AS spine MRI (ASspiMRI) scoring (0–69).
