Campath (alemtuzumab) is a monoclonal antibody sometimes used to treat CLL. Rituxan (rituximab) is also commonly used but is not yet approved for this disease.
You take Campath by intravenous (IV) needle either every day or many times a week. You can get this as an outpatient, meaning you don't have to stay in the hospital overnight. Each treatment lasts about two hours.
Rituximab is given by injection into a vein (IV) over a few hours, usually once every several weeks.
