Secukinumab in Tumor Necrosis Factor (TNF) - Inadequate Response (IR) Psoriasis Participants.

This study was designed to prove and quantify the hypothesis that secukinumab is effective, safe and well tolerated in the treatment of moderate to severe chronic plaque-type psoriasis in patients who are inadequate responders to anti-TNFα therapy in a United Kingdom (UK) and Republic of Ireland) specific population.

There is no clear evidence or guidelines on appropriate treatment once a patient with moderate/severe psoriasis has failed to respond to anti-TNFα therapy, whether a single anti-TNFα therapy failure or multiple anti-TNFα therapy failures. Numerous double-blind, double-dummy, randomised, parallel-group, active and placebo controlled studies have already been designed and run for the Phase III secukinumab clinical development program, in accordance with Health Authorities guidelines and feedback, including Food and Drug Administration (FDA) and European Medicines Agency (EMA). None of these specifically studied patients who have failed to respond to anti-TNFα therapy as defined by National Institute for Health and Care Excellence (NICE) guidelines. Therefore, this study utilises a pragmatic, open-label, non-comparator design, which has been shown to be appropriate in similar studies looking at anti-TNFα therapy in patients failing on other therapies (Papp et al. 2012; Strober et al. 2011), to answer the question of whether secukinumab is an appropriate choice in patients who have failed to respond to anti-TNFα therapy (TNF-IR) per NICE definitions, whether a single anti-TNFα therapy failure or multiple anti-TNFα therapy failures.
