Management of moderate to severe psoriasis with brodalumab-Real-world evidence from the LIBERO study.

Abstract

Brodalumab, a fully human monoclonal immunoglobulin IgG2 antibody that binds the human interleukin 17 receptor subunit A, is available for the treatment of moderate-to-severe plaque psoriasis in Europe since September 2017, but so far there are only a few studies on its use in real-world conditions. To assess the management of moderate-to-severe psoriasis with brodalumab 210 mg in daily practice after 12 and 52 weeks (W). In addition, patient profiles and treatment pathways are described. LIBERO is a prospective, multicenter, non-interventional study including adult patients with plaque psoriasis treated with brodalumab 210 mg. In total, 638 patients (65% male, mean age: 49.3 ± 14.4 years) from 148 sites in Germany were enrolled. The majority suffered from severe (51.1%) or very severe (13.1%) psoriasis according to physician global assessment (PGA0-5). When starting with brodalumab, 58.5% were biologic naïve and 41.5% were previously treated with another biologic, mainly adalimumab (18.5%) and secukinumab (17.9%). About 74.0% of patients met the primary endpoint of an absolute PASI ≤3 at ~W12 (n = 618, LOCF). The mean PASI was reduced significantly as of ~W2 from 17.2 (±11.7) to 9.7 (±8.8) and improved further to 3.3 (±6.3) at ~W12 (p < 0.001). At ~W52 85.5% of patients reached a PGA0/1-response (primary endpoint) and 54.1% patients were assessed as completely clear (PGA0) (both n = 399, as observed). Effectiveness of brodalumab was confirmed in relevant subgroup analysis by previous treatment regimen. Most frequently reported adverse events were nasopharyngitis (4.6%), psoriasis (4.6%) and arthralgia (4.1%), new safety signals were not detected. This representative, non-interventional study confirms the short- and long-term effectiveness and safety profile of brodalumab in the management of psoriasis in daily practice as well as in relevant treatment pathways.
