  • Patent number: 11542526
    Abstract: Provided herein is a conditionally-replicating serotype 5 adenovirus or adenoviral vector expressing a mutant E1A protein under control of a promoter that is responsive to hypoxia and inflammation and one or more immune modulators under control of a tumor-specific promoter. The adenovirus or adenoviral vector also comprises serotype 3 fiber and hexon proteins. Also provided is a method of inducing cytotoxicity in tumor cells using a composition containing the adenovirus or adenoviral vector.

  • Patent number: 9056133
    Abstract: This invention is related to the field of cancer treatment, more specifically to gene therapy in combination with a suitable chemotherapeutic agent. The present invention is related to a new oncolytic virus, which is able to inhibit the growth of malignant tumors or is a treatment of hyperproliferative mammalian cells, or is a treatment of cancer. The oncolytic virus works in combination with a suitable chemotherapeutic agent. More specifically, the present invention provides a pharmaceutical kit comprising an oncolytic adenovirus and a chemotherapeutic agent, and a method for the treatment of cancer.

  • Patent number: 8541566
    Abstract: The invention provides promoters inducible by reactive oxygen species (ROS), capable of driving the expression of a gene of interest, particularly in a tumor cell. More particularly, it refers to promoters inducible by reactive oxygen species, that may be used to drive the expression of a gene of interest, such as a therapeutic gene, or a reporter gene for use in image diagnosis. The promoters comprise at least a fragment of a promoter sequence responsive to said reactive oxygen species, and corresponding to a gene highly expressed in cancer cells, wherein the fragment of the promoter sequence responsive to reactive oxygen species (ROS) is selected from the group of: the VE element of the VEGF promoter, the E6 element of the promoter of the EGR-1 gene, the MMP-1 element and a chimeric promoter containing an E6 element and a VE element. It also provides vectors carrying a human therapeutic or non therapeutic gene of interest, operably linked to said promoter sequence and compositions comprising the same.
