Official title
A 16-week Randomized, Open-label, Multicenter Study to Assess the Superiority of Secukinumab Over Guselkumab in the Complete Treatment of Ustekinumab Resistant Psoriatic Plaques
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The aim of this study was to describe the effect of direct IL-17A inhibition with secukinumab as compared with the selective inhibition of IL-23 with guselkumab (p19 subunit blocker) in controlling inflammation in psoriatic plaques that remain active despite treatment with the non-selective IL-23 inhibitor ustekinumab (blocker of p40 subunit, shared by IL-12 and IL 23).
