          -  Life expectancy of at least 3 months

          -  Measurable disease in at least one target lesion, assessable by radiographic
             examination with Fludeoxyglucose-Positron Emission Tomography (FDG-PET) or computed
             tomography (CT), bone marrow evaluation showing involvement, or peripheral blood
             showing involvement of lymphoma
