Jean-Guy Delcros 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: 11648309
    Abstract: The application discloses method of treatment of cancer utilizing a linear or substantially linear epitope on netrin-1 that likely corresponds to the specific binding region of netrin-1 to receptor, in particular of the UNC5 class, especially UNC5B and UNC5A, or alternatively corresponds to a region nearby the specific binding region of netrin-1 to receptor that when bound to an antibody prevents netrin-1/receptor interaction. This determination of a linear epitope allows for the production of antibodies binding to netrin-1 and interfering with netrin-1/receptor interaction, thereby inducing apoptosis or cell death of tumour cells expressing or overexpressing netrin-1 and at least one netrin-1 receptor, owing the fact that this interaction inhibits netrin-1 binding to a receptor and the multimerization of the receptor. The application also discloses a murine monoclonal antibody directed against this epitope and various humanized forms thereof.

  • Publication number: 20130089548
    Abstract: A method for inducing apoptosis of tumoral cells in a patient having cancer cells bearing Cell-adhesion molecule-related/Downregulated by Oncogenes (CDO) receptors and expressing Sonic Hedgehog (SHH), including administering to the patient an effective amount of an agonist of CDO's apoptotic function, wherein the agonist is selected from the group consisting of a CDO fragment, a fusion protein comprising a CDO fragment, an antibody against SHH, and an siRNA which is capable of inhibiting SHH expression, and related CDO fragments, fusion proteins comprising a CDO fragment, antibodies against SHH, and siRNAs which are capable of inhibiting SHH expression.
