Patents by Inventor Worapol NGAMCHERDTRAKUL

Worapol NGAMCHERDTRAKUL 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).

  • Patent number: 12059500
    Abstract: Disclosed herein are therapeutic constructs including a delivery particle, at least one mitotic kinase inhibitor, and at least one immune checkpoint inhibitor. Also disclosed are therapeutic constructs including a mitotic kinase inhibitor, an immune checkpoint inhibitor, and a chemical linker. These therapeutic constructs cause cancer death by both therapeutic and immune effects and promote targeted delivery of more therapeutics to the surviving cancer cells in a positive feed-back loop. They enhance therapeutic index of free drugs and can be used intratumorally or systemically. This strategy can treat broad cancer types and is particular useful for cancer without obvious receptors for cancer-targeted delivery of otherwise toxic therapeutics.
    Type: Grant

    Inventors: Wassana Yantasee, Moataz Reda, Worapol Ngamcherdtrakul
  • Publication number: 20240075128
    Abstract: Disclosed are immunogenic constructs including: a nanoparticle; a cationic polymer electrostatically bound to an exterior surface of the nanoparticle and a stabilizer bound to the cationic polymer or the exterior surface of the nanoparticle; and an antigen or antigen producing agent. Optionally, the constructs may include adjuvant and/or one or more functional oligonucleotide(s) (e.g., siRNA or pDNA). Also disclosed are methods of using the provided immunogenic constructs for co-delivering an adjuvant, antigen, and optionally siRNA to a cell, inducing immune response in a subject, and treating or preventing an infectious disease in a subject.

  • Publication number: 20220249389
    Abstract: Disclosed herein are immunotherapeutic constructs comprising a delivery particle, at least one adjuvant, and one or more therapeutic agents/compounds that cause antigen release and/or modulate immunosuppressive tumor microenvironment. These immunotherapeutic constructs create adaptive immunity or anti-cancer immune response(s) that can be used, for instance, to prevent and treat broad types of cancer. Further disclosed are uses of the immunotherapeutic constructs, including to prevent and treat cancer in humans and animals.
