  • Publication number: 20220313643
    Abstract: Methods for treating cancer are disclosed which comprise administering to a subject T cells which have been pretreated ex vivo or in vitro with a fatty acid catabolism promoter to condition the T cell to use fatty acids rather than glucose for energy production. Still other methods comprise co-administering to a subject having a cancer characterized by a solid tumor (a) an immunotherapeutic composition targeting an antigen or ligand on the tumor cell; and (b) a compound or reagent that promotes the use of fatty acid catabolism by tumor antigen-specific T cells in the tumor microenvironment and/or T cells pretreated ex vivo with the fatty acid catabolism promoter to condition the T cell to use fatty acids rather than glucose for energy production for adoptive cell transfer. Both methods may also employ co-administration of a checkpoint inhibitor.

  • Publication number: 20220211835
    Abstract: The invention includes compositions and methods of generating a chimpanzee-derived adenovirus serotype AdC6 or AdC7 vector vaccine, wherein an early gene E1 genomic region is deleted, and wherein the nucleic acid sequence further comprises an expression cassette comprising a promoter sequence operably linked to a sequence encoding a heterologous protein, wherein the heterologous protein is at least one HIV protein selected from the group consisting of gp140 and Gag, wherein gp140 is from a Chinese HIV clade selected from the group consisting of B, AE, BC and C, and wherein Gag is from a Chinese HIV clade B. Furthermore, the invention encompasses a pharmaceutical composition for vaccinating a mammal as well as a protein expression system.

  • Publication number: 20210393757
    Abstract: The present invention relates to compositions and methods for generating a nucleic acid delivery system comprising a nucleic acid sequence encoding a heterologous protein comprising a canine tumor-specific antigen (canine melanoma polyepitope (K9Melapoly)) and an inhibitor of an immuno-inhibitory pathway (HSV-1 gD). Additionally, the current invention includes compositions and methods of treating and/or preventing or immunizing a canine against melanoma, and methods of inducing an effector and memory T cell immune response in a canine administered the nucleic acid delivery system of the invention.

  • Publication number: 20210113613
    Abstract: Methods for treating cancer are disclosed which comprise administering to a subject T cells which have been pretreated ex vivo or in vitro with fenofibric acid (FFA), an FFA prodrug, or a derivative thereof that has PPAR-? agonist activity. These compounds promote the use of fatty acid catabolism rather than glucose for energy and promote enhanced recovery of, and biomass production by, the pre-treated T cells. Still other methods comprise co-administering to a subject having a cancer characterized by a solid tumor an immunotherapeutic composition targeting an antigen or ligand on the tumor cell and the pretreated T cells. The method may also employ co-administration of a checkpoint inhibitor. Novel compositions comprise the pre-treated T cells. Novel FFA prodrugs are provided.
