Immunoconjugate comprising vhh domain binding cd123 and cytotoxic agent
A recently granted patent (Publication Number: US11919963B2) discloses an immunoconjugate designed for targeted cancer therapy. The immunoconjugate comprises a polypeptide with at least one VHH domain that binds to CD123, a protein often overexpressed in cancer cells, along with a cytotoxic agent. The VHH domain sequences are specified in the claims, ensuring high specificity and efficacy in targeting CD123. Additionally, the patent mentions the humanization of VHH domains and the inclusion of an Fc region in the polypeptide, which can form dimers under physiological conditions, enhancing the therapeutic potential of the immunoconjugate.
Moreover, the patent covers a method of treating cancer by administering the immunoconjugate to patients with various types of lymphomas, leukemias, and other cancers where CD123 is a viable target. The patent also includes provisions for combining the immunoconjugate with other anti-cancer therapies like chemotherapeutic agents, biologics, radiation therapy, CAR-T therapy, or oncolytic viruses for a synergistic effect. Furthermore, the patent extends to isolated T cells engineered to express VHH domains targeting CD123, offering a novel approach to cancer immunotherapy. These engineered T cells, including CAR-T cells, can be used in personalized cancer treatment strategies, potentially revolutionizing the field of oncology with their targeted and potent anti-cancer effects.
