Combination treatment with 4-1BBL/anti-CD20 fusion protein and anti-CD3/anti-CD20 diabody led to significantly increased T-cell cytotoxicity to human B-lymphoma cells in vitro and drastically more potent tumor inhibitory activity in vivo in xenografted B-cell lymphoma in severe combined immunodeficiency disease mice.
Measles virus (MV)-PNP H(blind)antiCD20 is a CD20-targeted and prodrug convertase-armed MV that temporarily controls growth of lymphoma xenografts in severe combined immunodeficiency (SCID) mice in combination with fludarabine phosphate (fludarabine).
