title: Clinical considerations of efalizumab therapy in patients with psoriasis.
abstract: Psoriasis is a chronic, incurable disease that often requires decades of therapy to maintain disease control. Efalizumab is a recombinant monoclonal IgG1 antibody approved for use in patients with chronic moderate-to-severe plaque psoriasis. To date, efalizumab has been evaluated extensively in more than 3500 patients, including in studies that have evaluated its efficacy and safety during extended use. Just as psoriasis fluctuates in severity, the response to treatment with efalizumab can vary among patients. On the basis of my personal experience managing patients in and out of clinical trials, most patients benefit from efalizumab. The possibility exists of intercurrent events during efalizumab therapy, such as the development of a transient localized papular eruption or mild arthralgia or, in a few patients, a generalized inflammatory flare or severe arthralgia. However, there are techniques to potentially manage these events in a manner that maximizes patient comfort and compliance. If dermatologists become comfortable recognizing the subset of patients who are overall excellent responders but develop a papular eruption or mild and manageable arthralgia, they will be able to readily incorporate this effective biologic into their daily practice. In this article, clinical trial data and case reports illustrate recommended patient management techniques and the substantial long-term benefits that psoriasis patients may realize with efalizumab therapy.
