Background Targeted biologic therapies have made a significant impact on the treatment for moderate to severe psoriasis. In the United Kingdom, the National Institute for Health and Clinical Excellence recommends etanercept, a human recombinant tumour necrosis factor (TNF) receptor fusion protein, for moderate to severe psoriasis patients who have failed conventional therapies. There is, however, no data available on the role of other TNF antagonists for patients who have failed etanercept. Adalimumab, a fully human, anti‐TNF monoclonal antibody, is approved for treatment of moderate to severe psoriasis. Objectives To assess the efficacy and safety of adalimumab (40 mg weekly) in psoriasis patients who were non‐responders to high‐dosage etanercept (50 mg twice weekly). Methods All patients attending a tertiary referral service for severe psoriasis who were non‐responders to high‐dosage etanercept [i.e. failed to achieve ≥ 50% improvement in Psoriasis Area and Severity Index (PASI 50) after 12 weeks of treatment] were considered for open‐label adalimumab therapy for 12 weeks. Details on clinical course, PASI, Dermatology Life Quality Index (DLQI) and adverse events were recorded at baseline and weeks 2, 4, 8, and 12. Results Four of five patients in this study had reached at least PASI 50 by week 12. Of these, two patients achieved a 75% improvement in PASI (PASI 75). No serious adverse events were reported. Conclusions Initial data from this open‐label prospective evaluation suggests that weekly adalimumab therapy is an effective treatment for patients with severe psoriasis who had failed to respond to at least 3 months of high‐dosage etanercept.
