Effectiveness of Long-Term Treatment with Brodalumab on Anxiety or Depressive Symptoms in Japanese Patients with Psoriasis: The ProLOGUE Study

Abstract Introduction Evidence on treatment effectiveness in patients with psoriasis having anxiety or depressive symptoms helps shared decision-making. This single-arm, open-label, prospective study—ProLOGUE—was conducted to assess the effectiveness of brodalumab on self-assessed anxiety and depressive symptoms in Japanese patients with psoriasis. Methods Patients aged ≥ 18 years with plaque psoriasis without peripheral arthritis symptoms who had responded inadequately to current therapies were enrolled at 15 Japanese facilities and received brodalumab 210 mg subcutaneously. Results A total of 73 patients were enrolled (male, 82%; median age, 54 years). The proportion of patients without anxiety symptoms changed significantly from baseline (72.6%) to weeks 12 (88.9%, p = 0.008) and 48 (87.7%, p = 0.02); the proportion of patients without depressive symptoms did not change significantly. The Generalized Anxiety Disorder-7 score (median [quartile(Q)1–Q3], 1.0 [0.0–5.0] at baseline; 0.0 [0.0–2.0] at week 12, p = 0.008; and 0.0 [0.0–1.0] at week 48, p = 0.007) and Patient Health Questionnaire-8 score (median [Q1–Q3], 2.0 [0.0–4.0] at baseline; 1.0 [0.0–4.0] at week 12, p = 0.03; and 0.0 [0.0–2.0] at week 48, p = 0.004) significantly decreased after treatment. The median Psoriasis Area and Severity Index scores after treatment were
