Patents by Inventor Nibedita Chattopadhyay

Nibedita Chattopadhyay 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: 20240092860
    Abstract: The instant invention provides binding proteins (“CD38-binding proteins”) which each comprise (1) a CD38-binding region for cell-targeting and (2) a Shiga toxin A Subunit effector polypeptide (“Shiga toxin effector polypeptide”). The Shiga toxin effector polypeptide components of the CD38-binding proteins may comprise a combination of mutations relative to a wild-type Shiga toxin sequence providing (1) de-immunization and/or (2) a reduction in protease sensitivity; wherein each Shiga toxin effector polypeptide retains one or more Shiga toxin function, such as, e.g., stimulating cellular internalization, directing intracellular routing, catalytic activity, and/or potent cytotoxicity. The CD38-binding proteins may have one or multiple uses, e.g., the selective killing of a specific CD38-expressing cell-type; and more generally, for the diagnosis and treatment of cancers and disorders involving CD38-expressing cells, e.g., in CD38-positive hematopoietic cancers such as multiple myeloma.

  • Patent number: 9920373
    Abstract: Disclosed are markers associated with sensitivity to treatment with proteasome inhibitors. Sensitivity is observed when RAS gene is wild type in tumor cells. Compositions and methods are further provided to assess markers of marker genes to predict outcome of treatment using proteasome inhibitors to patients having a solid tumor, such as a lung tumor or a colon tumor.
