DESCRIPTIONPsoriasis is characterized by red, thickened plaque with a silvery scale. Lesions may vary in size and degree of inflammation. The extent of skin involvement is categorized as localized or generalized based on the severity of the disease and its overall impact on the patient's quality of life. Medical treatment for localized psoriasis begins with a combination of topical corticosteroids and coal tar or calcipotriene. For lesions that are difficult to control with initial therapy, anthralin or tazarotene may be tried. The primary goal of therapy is to maintain control of lesions. Cure is seldom achieved. If control becomes difficult or if psoriasis is generalized, patients may benefit from phototherapy and/or systemic therapy.
Adalimumab (Humira®) is a recombinant human IgG1 monoclonal antibody specific for human tumor necrosis factor (TNF). Increased levels of TNF are also found in psoriasis plaques. Adalimumab may reduce the epidermal thickness and infiltration of inflammatory cells.
Alefacept (Amevive®) is an immunosuppressive dimeric fusion protein that interferes with lymphocyte activation by specifically binding to the lymphocyte antigen, CD2, and inhibiting LFA-3/CD2 interaction. Activation of T lymphocytes involving the interaction between LFA-3 on antigen-presenting cells and CD2 on T lymphocytes plays a role in the pathophysiology of chronic plaque psoriasis.
Etanercept (Enbrel®) is a dimeric fusion protein that binds specifically to tumor necrosis factor (TNF) and blocks its interaction with cell surface TNF receptors. Etanercept inhibits binding of both TNFa and TNFß to cell surface TNF receptors, rendering TNF biologically inactive which can result in a significant reduction in inflammation.
Infliximab (Remicade®) is a monoclonal antibody that blocks activity of a key inflammatory mediator called tumor necrosis factor alpha (TNF-alpha).
Ustekinumab (Stelara™) is a human IgG1k monoclonal antibody against the p40 subunit of the IL-12 and IL-23 cytokines. IL-12 and IL-23 are naturally occurring cytokines that are involved in inflammatory and immune responses.
Raptiva® was voluntarily withdrawn from the market by the manufactuer, GenentechTM effective June 8, 2009. This was the result of several cases of reported progressive multifocal leukoencephalopathy in patients who were taking Raptiva® .
FDA APPROVED INDICATIONS
Alefacept (Amevive®), adalimumab (Humira®), ustekinumab (Stelara™), and etanercept (Enbrel®) are approved for the treatment of adult patients with moderate to severe chronic plaque psoriasis who are candidates for systemic therapy or phototherapy.
Infliximab (Remicade®) is indicated for the treatment of adult patients with chronic severe (i.e. extensive and/or disabling) plaque psoriasis who are candidates for systemic therapy and when other systemic therapies are medically less appropriate
