This review delivers a commentary on the first decade of biologics’ use in psoriasis and provides a glimpse of the pipeline of therapies currently in development for psoriasis that will enhance the therapeutic armamentarium available to the dermatologist. In addition, the authors revisit the rationale for the development of biological therapies, inventory the available therapies of today, and retrospectively assess their impact on the dermatology practice as it relates to the management of patients with psoriasis.

Efalizumab is a recombinant humanized monoclonal IgG 1 antibody that targets CDlla, a cell surface protein that plays a key role in the T-cell-mediated steps leading to the pathogenesis of psoriasis. The efficacy and safety of efalizumab have been studied extensively in patients with moderate to severe chronic plaque psoriasis. Clinical trial data developed in several large phase 3 studies have demonstrated that efalizumab rapidly improves both physician- and patient-assessed measures of clinical efficacy, and that the observed changes are sustainable over extended periods of continuous treatment, with a favorable safety profile. Efalizumab represents a new therapeutic option for the long-term management of moderate to severe chronic plaque psoriasis.
