  • Publication number: 20230390424
    Abstract: Compositions and methods for treating a solid cancer in a subject by administering an effective amount of a radioisotope labeled trophoblast glycoprotein (5T4)-targeting agent are provided. The 5T4-targeting agent may be an antibody against 5T4 labeled with 225Ac, 177Lu, 131I, 90Y, 213Bi, 211At, 212Bi, 227Th, or 212Pb. The solid cancer may be a 5T4-positive tumor. The effective amount of the radiolabeled 5T4-targeting agent may be a maximum tolerate dose administered in a single bolus or in fractionated doses that together equal the maximum tolerated dose. The methods may further include administration of additional agents, such as chemotherapeutic agents, immune checkpoint therapies, and/or DNA damage response inhibitors.

  • Publication number: 20220211885
    Abstract: This invention provides a method for depleting a subject's hematopoietic stem cells that includes administering to the subject an effective amount of a radiolabeled antibody against CD34, CD117, or CD135, where preferred radiolabels include 131I and 225Ac. This invention also provides a method for treating a subject afflicted with a non-cancerous disorder treatable via genetically edited cell therapy, where the method includes (i) administering to the subject an amount of the radiolabeled antibody effective to deplete the subject's hematopoietic stem cells, and (ii) after a suitable time period, performing the therapy on the subject to treat the subject's disorder. Finally, this invention provides articles of manufacture for performing the subject methods.

  • Patent number: 9375488
    Abstract: The invention provides conjugates that consist of a drug moiety agent and a cell binding agent that target human fibroblast growth factor receptor 3 (FGFR3). These conjugates have therapeutic use as they are designed and tailored to target a specific cell population and deliver a powerful cytotoxin inside the cell. The conjugate of the present invention has significant advantages over other conjugates known in the art by providing a targeted tumor therapy as well as bystander activity to neighboring cells in an important oncology receptor that is only moderately expressed.

  • Patent number: 7972600
    Abstract: The present invention relates to a method of treating prostate cancer with androgen deprivation therapy and an insulin-like growth factor receptor (IGF-IR) antagonist. Although the response rate of prostate cancer to androgen deprivation therapy (ADT) is high, surviving cancer cells invariably become androgen independent (AI) and tumor growth follows. The invention inhibits or delays transition of androgen dependent cancer to androgen independent cancer, significantly decreases risk of recurrence, and improves treatment outcome.
