Novel therapies are needed for pediatric acute lymphoblastic leukemia resistant
to conventional therapy. While emerging data suggest leukemias as possible
targets of oncolytic attenuated measles virus, it is unknown whether measles
virus can eradicate disseminated leukemia, in particular pediatric acute
lymphoblastic leukemia. We evaluated the efficacy of attenuated measles virus
against a large panel of pediatric xenografted and native primary acute
lymphoblastic leukemias ex vivo, and against four different acute lymphoblastic
leukemia xenografts of B-lineage in non-obese diabetic/severe combined
immunodeficient mice. Ex vivo, attenuated measles virus readily spread among and
effectively killed leukemia cells while sparing normal human blood cells and
their progenitors. In immunodeficient mice with disseminated acute lymphoblastic
leukemia a few intravenous injections of attenuated measles virus sufficed to
eradicate leukemic blasts in the hematopoietic system and to control central
nervous system disease resulting in long-term survival in three of the four
xenografted B-lineage leukemias. Differential sensitivity of leukemia cells did
not require increased expression of the measles entry receptors CD150 or CD46 nor
absence of the anti-viral retinoic acid-inducible gene I/melanoma differentiation
associated gene-5 /interferon pathway. Attenuated oncolytic measles virus is
dramatically effective against pediatric B-lineage acute lymphoblastic leukemia
in the pre-clinical setting warranting further investigations towards clinical
translation.
