Patents by Inventor Ivan Bergstein

Ivan Bergstein 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: 7608259
    Abstract: Improved methods for treatment of cancer which involve the targeting of slow-growing, relatively mutationally-spared cancer stem line are provided. These methods are an improvement over previous cancer therapeutic methods because they provide for very early cancer treatment and reduce the likelihood of clinical relapse after treatment.

  • Publication number: 20090252742
    Abstract: The present invention provides antibodies that bind to the IL-3 receptor alpha subunit alpha (Il3R?) chain, and compositions comprising such antibodies. The present invention provides methods for inhibiting or reducing an IL3R?-expressing cell population, the methods comprising contacting a population of IL3R?-expressing cells (e.g., cancer cells and/or cancer stem cells) with an antibody that binds to IL3R?. The present invention also provides antibody conjugates comprising an antibody that binds to an IL3R? chain linked to a cytotoxic agent or anticellular agent and compositions comprising such conjugates. The present invention also provides methods for preventing, treating and/or managing a disorder associated with IL3R?-expressing cells (e.g., a hematological cancer), the methods comprising administering to a subject in need thereof an antibody that binds to IL3R?.

  • Publication number: 20080267947
    Abstract: Provided are methods for treating cancer in a patient, comprising administration of a therapeutically effective regimen of cantharidin or cantharidin analog of formula of formula I, II or III wherein R1, R2, R3, R4, R5, R6, R7, R8, R11, R12, A, Y and Z are as set forth herein, or a pharmaceutically acceptable salt thereof, to a patient in need thereof. In some embodiments of the methods, the therapeutically effective regimen stabilizes, reduces or eliminates cancer stem cells. In some embodiments of the methods, the therapeutically effective regimen reduces or eliminates cancer cells.

  • Publication number: 20080118432
    Abstract: The present invention is directed to methods of monitoring cancer stem cells in patients undergoing cancer therapy to determine whether the cancer therapy is an effective cancer therapy. The present invention relates to methods for monitoring the amount of cancer stem cells prior to, during, and/or following cancer treatment of a patient. In particular, the methods provide measuring the amount of cancer stem cells i) in a sample obtained from a patient and/or ii) in a patient via in vivo imaging, e.g. at different time points before, during or after a treatment regimen for cancer. The change in amount of cancer stem cells over time allows the physician to judge the effectiveness of the treatment regimen and then to decide to continue, alter, or halt the treatment regimen if need be. The present invention also provides kits for monitoring cancer stem cells prior to, during, and/or following cancer treatment of a patient.

  • Publication number: 20080118518
    Abstract: The present invention provides methods for stabilizing, reducing or eliminating cancer cells. In particular, the present invention provides prophylactically and/or therapeutically effective regimens for the prevention, treatment and/or management of cancer, the regimens comprising administering one or more cancer therapies to a subject to reduce a cancer cell population. The therapy(ies) in the prophylactically and/or therapeutically effective regimen can be administered at a lower dose than currently used or known to one of skill in the art and/or for a longer period of time and/or more frequently than currently administered or known to one of skill in the art.
