Psoriasis poses a substantial economic burden by reducing the work productivity of affected patients. We aimed to evaluate the negative impact of plaque psoriasis on work productivity and effectiveness of brodalumab in improving work productivity impairment in real-life employed patients. This analysis was conducted in employed patients from ProLOGUE, an open-label, multicenter, prospective cohort study (Japan Registry of Clinical Trials identifier: jRCTs031180037). Outcomes included association of Work Productivity and Activity Impairment-Psoriasis (WPAI-PSO) domain scores with scores from various patient-reported outcome measures or Psoriasis Area and Severity Index (PASI) scores at baseline. Change from baseline in WPAI-PSO domain scores following brodalumab treatment was also evaluated. Of the 73 patients enrolled, 51, 48, and 40 patients were considered employed at baseline, Week 12, and Week 48 of brodalumab treatment, respectively. In the model adjusted by age and sex, the work productivity loss score correlated with the Dermatology Life Quality Index (DLQI), itch Numeric Rating Scale (NRS), Patient Health Questionnaire-8 (PHQ-8), and skin pain NRS scores (partial Spearman correlation coefficient [ρ] = 0.608, 0.510, 0.461, and 0.424, respectively); presenteeism score correlated with the DLQI, itch NRS, and skin pain NRS scores (ρ = 0.568, 0.500, and 0.403, respectively); and activity impairment score correlated with the DLQI and PHQ-8 scores (ρ = 0.530 and 0.414, respectively). None of the WPAI-PSO domain scores correlated with the PASI score. All WPAI-PSO domain scores (except absenteeism) significantly reduced from baseline to Weeks 12 (p < 0.0001) and 48 (p < 0.001) with brodalumab treatment. In conclusion, work productivity impairment in psoriasis was associated with various subjective symptoms that can be captured using patient-reported outcome measures. Brodalumab treatment improved work productivity in real-life employed patients with plaque psoriasis.
