E.2.1 | Main objective of the trial |
The objective of this study is to evaluate the efficacy and safety of continuing versus withdrawing therapy with adalimumab 40 mg given every other week (eow) subcutaneously (SC) in maintaining remission in subjects with non-radiographic axial Spondyloarthritis (nr-axSpA). |
El objetivo de este estudio es evaluar la eficacia y la seguridad del tratamiento continuo frente a la interrupción del tratamiento con 40 mg de adalimumab administrado por vía subcutánea (SC) cada dos semanas (cds) en el mantenimiento de la remisión en sujetos con espondiloartritis axial no radiográfica (EsA-ax-nr). |
