About
To evaluate the impact of treatment with a non-steroidal anti-inflammatory drug (NSAID) - Celecoxib - when added to anti-tumour necrosis factor (TNF) therapy - Golimumab - as compared to anti-TNF therapy (Golimumab) alone on progression of structural damage in the spine over two years in patients with ankylosing spondylitis (AS).
Full description
The aim of the proposed trial is to evaluate the efficacy of combined treatment with a non-steroidal anti-inflammatory drug (NSAID) added to anti-tumour necrosis factor (TNF) therapy as compared to anti-TNF therapy alone on progression of structural damage in the spine over two years in patients with ankylosing spondylitis (AS). The trial consists of two phases. In the phase I (run-in phase), patients with active AS despite treatment with NSAIDs and elevated C-reactive protein will be included and treated with a TNF blocker (golimumab). Patients with good clinical response to golimumab at week 12 will be eligible for the phase II (core phase) of the study and will be randomized 1:1 to 1) golimumab + celecoxib (experimental intervention) for 2 years (weeks 12-108) or 2) golimumab alone (control intervention) also for 2 years. The primary outcome parameter will be the absolute progression of the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) - currently a standard of structural spinal damage progression evaluation in AS - over two years of therapy (weeks 12-108).
