The condition and the treatment
Chronic lymphocytic leukaemia, which is also known as CLL, is a cancer of a type of white blood cell (called the BÂ lymphocytes). The cancerous lymphocytes multiply in an uncontrolled way and stop other blood cells working properly.
Obinutuzumab (Gazyvaro) binds to the surface of lymphocytes, causing them to be destroyed. It is given with a drug called chlorambucil to slow down the progress of the disease.
