Abstract
Etanercept (Enbrel®), a tumor necrosis factor (TNF)-α antagonist produced by recombinant technology, is approved for use in the US as subcutaneous monotherapy in adults with moderate-to-severe psoriasis who are candidates for systemic therapy or phototherapy. The drug is also indicated in patients with psoriatic arthritis, in whom it may be used in combination with methotrexate.
In well designed trials in patients with moderate-to-severe psoriasis, short-term etanercept therapy (typically 25 or 50mg twice weekly) significantly increased the proportion of patients achieving a 75% reduction in the Psoriasis Area and Severity Index score compared with placebo. Similarly, in well designed trials in patients with psoriatic arthritis, treatment with short-term etanercept 25mg twice weekly, alone or in combination with methotrexate, improved clinical features of the disease, while radiographic progression of joint damage appeared to be significantly slowed in a nonblind 1-year extension. Short-term etanercept therapy was well tolerated in patients with psoriasis or psoriatic arthritis. Etanercept is thus a valuable new option for the treatment of patients with chronic moderate-to-severe plaque psoriasis (who are candidates for systemic therapy or phototherapy or have failed other systemic therapies) or with psoriatic arthritis.
