The invention provides for modified reovirus nucleic acid sequences and modified reovirus polypeptide sequences as well as reoviruses containing such modified nucleic acid or polypeptide sequences. The invention also provides for pharmaceutical compositions that include reoviruses having a modified sequence as well as methods of making and using such reoviruses.

The present invention provides an oncolytic virus comprising nucleotide sequence(s) encoding one or more immune checkpoint modulator(s). It also concerns a pharmaceutical composition comprising effective amount of said oncolytic virus and, eventually, a pharmaceutically acceptable vehicle and its use for treating proliferative diseases such as cancers.

The present disclosure relates to one or more modified avian-virus based agents, therapies, treatments, and methods of use of the modified avian-virus based agents and/or therapies and/or treatments for cancer. The disclosure also provides for methods of generating modified avian-virus based agents.

Compositions and methods are provided that relate to an attenuated reovirus exhibiting oncolytic activity toward cancer cells while displaying reduced lytic activity toward non-malignant cells. Exemplified is an attenuated human reovirus derived from persistently infected fibrosarcoma cells that lacks wild-type reovirus S1 and S4 genes and consequently lacks a detectable reoviral outer capsid .sigma.1 protein and expresses a mutated reoviral outer capsid .sigma.3 protein.

Disclosed are recombinant oncolytic viruses that express one or more reovirus fusion-associated small transmembrane FAST) proteins and uses thereof. The oncolytic activity of the recombinant oncolytic viruses expressing FAST proteins can be used to treat primary and metastatic cancers, especially from breast and colon cancers.

The present invention relates to a use of squirrel fibroma virus and a reovirus for preventing or treating cancer. A pharmaceutical composition comprising the squirrel fibroma virus and the reovirus, or a biological sample treated with the two viruses according to the present invention does not affect human normal cells but exhibits oncolytic activity by specifically infecting cancer cells, resulting in the inhibition of cancer cell growth.
