Improved effectiveness from individualized dosing of self-administered biologics for the treatment of moderate-to-severe psoriasis: a 5-year retrospective chart review from a Spanish University Hospital

Background: Biologics for moderate-to-severe psoriasis are expensive and treatment substitutions may vastly increase cost. Moreover, administration regimens in routine practice may differ from recommended guidelines. Objectives: To evaluate long-term effectiveness, regimen, drug-survival, and efficiency of self-administered biologics in clinical practice. Methods: We performed a 5-year retrospective study in 72 patients (44 ± 14 years old) with moderate-to-severe psoriasis at the University Hospital La Plana (Vila-real, Spain), treated with subcutaneous biologics. We determined the effectiveness (PASI 75 or PASI < 5), and drug-survival using Kaplan-Meier estimates, and analyzed reasons for …
