英文摘要
Abstract:
Armed oncolytic viruses are an emerging therapeutic strategy for many cancers. The parvoviruses are the
smallest viruses currently being developed as oncotherapeutic agents, and are non-enveloped and extremely
rugged, simplifying their production, purification and storage, as well as enhancing their tissue penetration
properties. Rodent protoparvoviruses can infect human cells only if neoplastically transformed, and thus are
intrinsically oncotropic - the rodent protoparvovirus H-1 is currently in Phase I/IIA clinical trials against
glioblastoma and pancreatic cancer. We have developed a replicating, but non-propagating, parvoviral vector
system, which can be packaged into tumor cell target-enhanced capsid selected in vitro. These dual
transgene vectors express secreted, soluble versions of murine or human PD-1 (sPD-1), or an anti-CTLA-4
camelid nanobody, coordinately with the murine co-stimulatory molecules CD80 or CD48, to render the tumor
cell itself an effective antigen presenting cell. We will test the hypothesis that the secreted transgene products
will effectively block the two major immune checkpoint pathways when secreted directly within the tumor
microenvironment, potentially avoiding the side-effects associated with systemic administration of immune
checkpoint inhibitors.
