ORLANDO-Alemtuzumab (Campath-1H) can induce responses in patients with refractory B-cell chronic lymphocytic leukemia (B-CLL) who have the 17p-/p53 genetic mutation, which is usually characterized by a dismal outcome, Stephan Stilgenbauer, MD, of the Department of Internal Medicine III, University of Ulm, Germany, reported at the 43rd Annual Meeting of the American Society of Hematology (abstract 3211). The researchers used alemtuzumab to treat 11 patients with B-CLL, as well as 4 with T-prolymphocytic leukemia (T-PLL) and 1 with Sézary syndrome.
