Patents by Inventor Nanhai G. Chen

Nanhai G. Chen 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: 20230008052
    Abstract: Clonal strains of vaccinia viruses are provided. Also provided are methods of identifying and isolating attenuated and oncolytic clonal strains from virus preparations. Modified recombinant forms of the clonal strains also are provided. The clonal strains and virus preparations can be used for diagnostic and therapeutic methods, in particular for therapy and diagnosis or monitoring treatment of proliferative disorders, including neoplastic diseases, such as, but are not limited to, solid tumors and blood cancers.

  • Publication number: 20220348856
    Abstract: Manufacturing techniques for fabricating a polymer or other substrate optimized for growing cells is described, which takes the form of a micro-thin bag with gas permeable sides. Sides of the bag can be held at a fixed distance from one another with a multitude of tiny micropillars or other spacers extending between them, keeping the bag at a predetermined thickness and preventing the bag from collapsing and the sides from sticking together. In other embodiments, the sides may be held apart by gas pressure alone. A 0.01 ?m to 1000 ?m parylene or other biocompatible coating over the bag outsides controls the permeability of the bag material and provides a bio-safe area for cell growth. An alternate configuration uses open-cell foam with skins coated with a biocompatible coating. Tubes going into multiple bags can be connected to a manifold that delivers gaseous oxygen or removes carbon dioxide and other waste gases.

  • Patent number: 10238700
    Abstract: Provided are adjunct therapies for use in combinations and compositions with an oncolytic virus, such as a vaccinia virus. The adjunct therapies include co-administration and co-formulation of a complement inhibitor and/or a lipid emulsion composition with the oncolytic virus. Also provided herein are therapeutic methods using the adjunct therapies for treatment of disease and conditions employing an oncolytic therapeutic virus, such as for the treatment of hyperproliferative diseases or conditions including tumors or cancers.
