Abstract

Official abstract text for this publication.

Disclosed herein, in certain embodiments, is a method of inhibiting or treating a cancer with use of a TNF expressing myxoma virus. Also disclosed herein are methods of inhibiting or treating a cancer with use of a mononuclear peripheral blood cells and/or a bone marrow cells treated with a TNF-expressing myxoma virus. Some aspects relate to engineered myxoma virus and pharmaceutical compositions for use with one or more of the methods described herein.

First claim

Opening claim text (preview).

What is claimed is: 1. A pharmaceutical composition comprising a myxoma virus (MYXV) and a pharmaceutically-acceptable excipient, wherein the MYXV is engineered to express a tumor necrosis factor (TNF) protein, wherein a gene encoding the TNF protein is inserted between M134 gene and M136 gene within the MYXV genome. 2. The pharmaceutical composition of claim 1 , wherein the TNF protein is a TNF alpha protein. 3. The pharmaceutical composition of claim 1 , wherein the TNF protein is a cell surface expressed TNF protein. 4. The pharmaceutical composition of claim 1 , wherein the TNF protein is secreted by cells infected by the MYXV. 5. The pharmaceutical composition of claim 1 , wherein the TNF protein is a human TNF protein. 6. The pharmaceutical composition of claim 1 , wherein the MYXV is a genetically modified Laussane strain MYXV. 7. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition is formulated for systemic administration. 8. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition is formulated for local administration. 9. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition is formulated for parenteral administration. 10. The pharmaceutical composition of claim 1 , wherein the MYXV is capable of directly killing cancer cells infected by the MYXV and eliciting off-target killing of uninfected cancer cells. 11. The pharmaceutical composition of claim 10 , wherein the MYXV exhibits enhanced off-target killing of uninfected cancer cells as compared to a MYXV that is not engineered to express the TNF protein. 12. A composition comprising peripheral blood mononuclear cells (PBMCs), bone marrow (BM) cells, or a combination thereof treated ex vivo by a myxoma virus (MYXV) engineered to express a tumor necrosis factor (TNF) protein, wherein a gene encoding the TNF protein is inserted between M134 gene and M136 gene within the MYXV genome. 13. The composition of claim 12 , wherein the MYXV comprises a modification within or adjacent to one or more genes associated with rabbit cell tropism. 14. The composition of claim 12 , wherein the MYXV comprises a modification of M135R that impairs function of the M135R. 15. A method of inhibiting or treating a cancer in a subject in need thereof, comprising administering to the subject a pharmaceutical composition comprising a myxoma virus (MYXV) and a pharmaceutically-acceptable excipient, wherein the MYXV is engineered to express a tumor necrosis factor (TNF) protein, wherein a gene encoding the TNF protein is inserted between M134 gene and M136 gene within the MYXV genome.
