Treatment of Moderate to Severe Psoriasis With High

Treatment of moderate to severe psoriasis often requires systemic therapy, including biologics. Partial response to biologics and relapses are commonly managed with dose escalation. Secukinumab is a relatively new biologic that is currently used to treat moderate to severe psoriasis. There has been no literature published on dose escalation of secukinumab. This article describes the off-label use of a higher dose of secukinumab (450 mg every 4 weeks) instead of the standard dosing (300 mg every 4 weeks) in 2 patients with moderate to severe psoriasis. The first case involves a male patient with a high body mass index (BMI) (≥30 kg/m2) and severe psoriasis who was started on secukinumab at 450 mg following a partial response to treatment with the standard 300-mg dose. His psoriasis significantly improved with the higher dose of secukinumab. The second case discusses a female patient with treatment-resistant psoriasis and a BMI of 31.6 kg/m2 who initially achieved a complete remission with standard dosing of secukinumab. Later, her psoriasis relapsed and she was dose-escalated to secukinumab 450 mg in an attempt to recapture response, but this dose escalation was unsuccessful. In both cases, there were no adverse events observed with a higher dose of secukinumab. These cases demonstrate that dose escalation of secukinumab (450 mg rather than on-label 300 mg every 4 weeks) may be considered in selected patients with incomplete clearance, particularly for those with a high BMI. However, secukinumab dose escalation may not be as beneficial in patients with loss of efficacy
