An observational study of the real-life management of psoriasis patients treated with etanercept according to the new reimbursement criteria (in Belgium)

AbstractBackground: This study described the number of patients with psoriasis receiving flexible (continuous/intermittent) dosing with etanercept (ETN) and the real-world economic impact. Methods: BeFlex was a prospective, observational study with a ≥1 year follow-up. Patients ≥18 years with moderate-to-severe psoriasis who were starting or re-starting treatment with ETN in alignment with Belgian reimbursement criteria were included. Cost of ETN was compared with cost of adalimumab, ustekinumab and infliximab using estimates from the National Institute for Sickness and Disability Insurance (INAMI/RIZIV). Results: In the flexible-dosing cohort (n = 121 with dose-regimen data), 66% were treated continuously and 34% intermittently. Baseline characteristics were similar across dosing cohorts. In the per-protocol cohort (n = 138), average ETN treatment duration/year was 40 weeks; 43 weeks continuous and 33 weeks intermittent. The overall mean interruption duration was 3.9 weeks/treatment cycle; 0.2 week conti...
