Summary Background Treatment with biologics may be indicated for patients with moderate‐to‐severe plaque psoriasis, but comparative evidence on cost‐effectiveness is limited. Switching of biologics is common, but it is unclear what the effect is of differences in sequences of biologics. Objectives To evaluate the cost‐effectiveness of different biologic treatment sequences for psoriasis based on real‐world evidence. Patients and methods A sequence model was developed to evaluate the costs and health effects of three consecutive lines of biologic treatments [for example adalimumab–etanercept–ustekinumab (Ada‐Eta‐Ust) vs. Eta‐Ust‐Ada] over a 10‐year time horizon in the Netherlands. The model was populated with data from the Dutch Bio CAPTURE registry and scientific literature. Analyses were conducted of cost per quality‐adjusted life year ( QALY ) and uncertainty was addressed by probabilistic as well as scenario analyses. Results Treatment of psoriasis with biologics for a 10‐year period was estimated to be associated with a cost of €141 962 to €148 442 per patient depending on the treatment sequence used. Cumulative health effects ranged from 7·79 to 8·03 QALY s. Starting with Ada or Ust seems favourable concerning cost and utilities compared with strategies starting with Eta, although credible intervals were partly overlapping. Conclusions The order in which biologics are used influences treatment cost‐effectiveness, both in terms of costs and health effects. Initiation of a biologic treatment sequence for psoriasis might best be done with Ada or Ust; Eta seems less optimal from a health‐economic perspective.
