David A. Spiegel 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: 12312621
    Abstract: The present invention relates to chimeric (preferably, bifunctional) compounds, compositions comprising those compounds and methods of treating cancer in a patient or subject, especially including metastatic cancer where cancer cells exhibit overexpression (heightened expression) of cell surface urokinase-type plasminogen activator receptor (urokinase receptor) compared to normal (non-cancerous) cells. The compounds preferably covalently bind to the urokinase receptor and recruit native antibodies of the patient or subject where the antibodies can selectively degrade and/or deactivate targeted cancer cells through antibody-dependent cellular phagocytosis and/or antibody-dependent cellular cytotoxicity (ADCC) against a large number and variety of cancers, thus providing cancer cell death and/or an inhibition of growth, elaboration and/or metastasis of the cancer, including remission and cure of the patient's cancer.

  • Patent number: 12042542
    Abstract: The present invention relates to compounds which function as antibody mimetic compounds. These compounds are bifunctional/multifunctional compounds which contain at least one cancer cell binding moiety which selectively binds to prostate specific membrane antigen (PSMA) and a FC receptor binding moiety which modulates an FC immune receptor, preferably a Fc?RI receptor. Compounds according to the present invention bind selectively to cancer cells which upregulate PSMA and through that interaction, place the Fc receptor binding moiety of the compound in proximity to a Fc receptor, preferably a Fc?RI receptor, which can modulate (preferably, upregulate) a humoral response in a patient to cancer cells. Through this biological action of the compounds according to the present invention, cancer cells, including metastatic cancer cells, especially prostate cancer cells can be immune regulated, resulting in the favorable therapy of cancer in a patient.
