Basel, Switzerland, 10 November 2009 - Lonza announces that GlaxoSmithKline (GSK) and Genmab's antibody ArzerraTM, which has just been approved for use in patients with chronic lymphocytic leukemia (CLL) by the US Food and Drug Administration (FDA), will be manufactured by Lonza.

About CLL
CLL is a cancer of the lymphocytes, a type of white blood cell. The lymphocytes can grow too quickly and live too long (disease usually gets worse slowly), and in time, overtake healthy white blood cells, red blood cells and platelets in the bone marrow. CLL is the most common adult leukemia and one of the most common malignant lymphoid diseases.
