NOVEL RECOMBINANT ANTIBODY SPECIFICALLY BINDING TO B CELL ANTIGEN, AND USE THEREOF

Resumen de: EP4818207A1

0001 The present invention relates to a recombinant polypeptide that specifically binds to B lymphocytes and a composition for preventing or treating B-cell lymphoma, comprising the recombinant polypeptide as an active ingredient. The present invention can significantly enhance direct cell death activity against tumor cells by conjugating concanavalin A, a ligand of MPZL1, to an antibody molecule that recognizes a B-lymphocyte-specific antigen such as CD20. Accordingly, unlike therapeutic antibodies that act mainly through antibody-dependent cell-mediated cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC) and antibody-dependent cellular phagocytosis (ADP), the recombinant polypeptide of the present invention does not depend on effector mechanisms of a patient's immune system. Therefore, the recombinant polypeptide can be usefully employed as an effective therapeutic composition even for cancer patients with reduced immune activity.

USE OF A MEDICAMENT SIMULTANEOUSLY TARGETING THE TYROSINE KINASE ACTIVITY AND GEF ACTIVITY OF EGFR

Resumen de: EP4817602A1

The present invention provides an EGFR inhibitor for use in the preparation of a medicament for treating diseases mediated by guanosine exchange factor (GEF) activity or co-mediated by guanosine nucleotide exchange factor (GEF) activity and EGFR tyrosine kinase activity, wherein the diseases are selected from the group consisting of: lung cancer, colon cancer, breast cancer, endometrial cancer, thyroid cancer, glioma, squamous cell carcinoma, prostate cancer, melanoma, leukemia, and glioblastoma. Specifically, the present invention has discovered that in addition to its conventional tyrosine kinase activity, EGFR also possesses a GEF function that promotes the activation of Ras homologous protein (Rheb), this function is independent of its tyrosine kinase activity and relies critically on the glutamate residue at position 804 on the EGFR molecule. The Rheb-GEF activity of EGFR induces allosteric activation of mammalian target of rapamycin complex 1 (mTORC1), ultimately promoting tumor growth.
