Alemtuzumab: evidence for its potential in relapsing-remitting multiple sclerosis.

ABSTRACT: Alemtuzumab (previously known as Campath(®)) is a humanized monoclonal antibody directed against the CD52 antigen on mature lymphocytes that results in lymphopenia and subsequent modification of the immune repertoire. Here we explore evidence for its efficacy and safety in relapsing-remitting multiple sclerosis. One Phase II and two Phase III trials of alemtuzumab versus active comparator (interferon beta-1a) have been reported. Two of these rater-blinded randomized studies assessed clinical and radiological outcomes in treatment-naïve patients; one explored patients who had relapsed despite first-line therapy. Compared to interferon beta-1a, alemtuzumab reduced the relapse rate by 49%-74% (P < 0.0001), and in two studies it reduced the risk of sustained disability accumulation by 42%-71%
