CAMBRIDGE, Mass., March 5 /PRNewswire/ -- Biogen, Inc. (Nasdaq: BGEN) today announced that retreatment with AMEVIVE(TM) (alefacept) in patients with moderate to severe chronic plaque psoriasis demonstrated positive results similar to that of the initial course of treatment. The results from this Phase II multicenter retreatment trial were presented at the annual meeting of the American Academy of Dermatology in Washington, DC.

Results from an earlier Phase II randomized, placebo controlled, double- blind, multiple-dose study in patients with moderate to severe chronic plaque psoriasis were previously reported. Because AMEVIVE is intended to be used as intermittent therapy, following the completion of the Phase II trial, patients from the study could elect to enroll into a retreatment protocol. The retreatment study, which is an on-going trial, is designed to determine the tolerability and efficacy of repeated courses of treatment with AMEVIVE. A large percentage of patients opted for retreatment. In total, 174 people have enrolled into the retreatment study.

The clinical response to AMEVIVE(TM) (alefacept) was consistent over repeated courses of treatment, suggesting that subsequent courses have a similar profile as the initial course of treatment. Patients received two courses of study therapy, and clinical response was evaluated at two weeks post dosing using the Psoriasis Area and Severity Index (PASI). Responses were observed within the first four weeks and tended to be more rapid with the second course of treatment.

There were no reports of disease rebound, a condition where a patient's psoriasis becomes substantially more severe than at baseline once treatment is withdrawn.

Burt A. Adelman, M.D., Biogen's Vice President of Medical Research, said, "The potential of AMEVIVE to provide the needed long-term and sustained solution for patients with moderate to severe chronic psoriasis is an exciting discovery for us. These data move us closer to our final goal of improving both the duration of response and safety for patients with moderate to severe chronic plaque psoriasis. We are looking forward to the results of the Phase III clinical trials which will be available mid-year."

AMEVIVE is a disease-modifying agent with a highly selective mode of action targeting a subset of T-cells - the memory effector T-cells - that play a critical role in the pathogenesis of psoriasis. Earlier Phase II trials yielded promising results including remission in some patients without rebound. To date more than 1,500 people have been treated with AMEVIVE.

Psoriasis is a T-cell mediated inflammatory disorder of the skin that can cause considerable discomfort. It is a disease for which there is no cure and affects people of all ages. Psoriasis affects approximately two percent of the populations of European and North America. The rash of psoriasis consists of red, scaly areas that commonly occur on the scalp, elbows and knees. In moderate and severe cases, the involved areas can be extensive and cover a substantial percentage of a patient's body. In addition, limited disease can be considered severe if occurring on critical areas such as the palms or soles. Although individuals with mild psoriasis can often control their disease with topical agents, more than one million patients worldwide require ultraviolet or systemic immunosuppressive therapy. Unfortunately, the inconvenience and risks of ultraviolet radiation and the toxicities of many therapies limit their long-term use. Moreover, patients usually have recurrence of psoriasis, and in some cases rebound, shortly after stopping immunosuppressive therapy. According to the National Psoriasis Foundation (NPF), the disease impacts a person's psychological well being and social functioning as well as their physical functioning.
