Latest Patents

Hirofumi Sakumoto holds a patent for an anti-CLDN6 antibody. This invention relates to an antibody that binds to Claudin6 (CLDN6) expressed on cell membranes. The antibody recognizes human CLDN6 in its native form on the cell membrane surface and exhibits cytotoxicity through antibody-dependent cellular cytotoxicity (ADCC) and/or complement-dependent cytotoxicity (CDC) activities against cancer cell lines that highly express human CLDN6. Furthermore, this antibody has a cell growth inhibitory effect when conjugated with a toxin on cancer cell lines that overexpress human CLDN6. Since human CLDN6 is overexpressed in tumor tissues such as lung adenocarcinoma, gastric cancer, and ovarian cancer, the anti-CLDN6 antibody is expected to accumulate significantly in these tumors, making it a promising antitumor agent.
