Sequential use of biologics in the treatment of moderate-to-severe plaque psoriasis.
A number of biologic agents, including the tumour necrosis factor (TNF) antagonists etanercept, adalimumab and infliximab, and the interleukin (IL)-12/IL-23 antagonist ustekinumab, are available for the treatment of moderate-to-severe plaque psoriasis in the U.K. Currently, the selection of the first biologic, and the choice of sequential biologics in the event of efficacy/tolerability concerns, is made using a limited evidence base. The efficacy of biologics, the potential mechanisms of primary and secondary failure and the evidence for sequencing therapy among TNF antagonists and between TNF antagonists and IL-12/IL-23 blockade are reviewed. As psoriasis biologics registers begin to produce long-term safety and efficacy data, therapy decisions in plaque psoriasis may become more objective, and it may be possible to individualize treatment based on clinical or pharmacogenetic information.
