Patents by Inventor Devanand Sarkar

Devanand Sarkar has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20210147502
    Abstract: Recombinant therapeutic cytokines (“therakines”) for the treatment of cancer are provided. The recombinant therakines include a truncated region of MDA-7/TL-24 (“M4”) not normally found in nature that has anti-cancer activity and a secretory signal which causes secretion of the therakine from plasmid/virus transduced normal and cancer cells and interaction of the therakine to MDA-7/IL-24 receptors on adjacent, neighboring and distant cancer cells. Therakine interaction results in bystander killing of the target cancer cell as well as adjacent, neighboring and distant cancer cells.

  • Publication number: 20200397839
    Abstract: A tropism modified cancer terminator virus (Ad.5/3-CTV; Ad.5/3-CTV-M7) has been found to have infectivity that is Coxsackie Adenoviral Receptor (CAR) independent. The Ad.5/3-CTV (Ad.5/3-CTV-M7) may be used alone or in combination with other therapeutic agents such as agents that augment reactive oxygen (ROS) production, HDAC inhibitors, MCL-1 inhibitors and Bcl-2 inhibitors to treat a variety of cancers particularly including malignant glioma (GBM), renal cancer, prostate cancer, and colorectal cancer.

  • Patent number: 10166300
    Abstract: The presently disclosed subject matter generally relates to genetic constructs and methods for their use in cancer imaging, cancer treatment, and combined imaging and treatment protocols. In particular, the presently disclosed subject matter relates to tripartite cancer theranostic nucleic acid constructs that permit simultaneous cancer specific viral replication, expression of a diagnostic gene product, and expression of a therapeutic gene.
