Management of moderate-to-severe plaque psoriasis with biologics: A treat-to-target position paper.

Treat-to-target (T2T) recommendations for the use of systemic therapies (including biologics) in patients with moderate-to-severe plaque psoriasis have been published by a few groups of experts worldwide. However, there remains considerable variability in the choice of target severity measure and timing of milestones. To develop consensus recommendations for implementing T2T strategies for the management of moderate-to-severe plaque psoriasis using biologics. An expert group of Canadian dermatologists (the Committee) convened to develop a T2T consensus statement. They held a virtual meeting during which a preliminary set of criteria was created. These criteria were then reviewed, modified, and recirculated until unanimous agreement was achieved. The Committee agreed that defining treatment target is multidimensional and should reflect objective severity measures, as well as clinician and patient-reported outcomes. The Committee unanimously proposes a criterion-based system for determining the achievement of treatment target. The proposed T2T approach presented here provides a clinical framework for defining treatment success, measuring progress toward treatment success, recognizing when treatment modifications are warranted, and recommending treatment optimization strategies.
