Comparison of the Effects of Secukinumab and Adalimumab Biosimilar on Radiographic Progression in Patients with Ankylosing Spondylitis: Design of a Randomized, Phase IIIb Study (SURPASS).
Summary
The purpose of this study is to demonstrate the impact of secukinumab on the progression of structural damage in the spine, as measured by the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) in patients with Ankylosing Spondylitis (AS).
