Patent No. EP3725810 (titled "Combination Therapy Involving Antibodies Against Claudin 18.2 For Treatment Of Cancer") was filed by Astellas Pharma on May 21, 2013. The application was issued on Jul 6, 2022.
Enhancing the effectiveness of cancer immunotherapy by combining an anti-CLDN18.2 antibody with agents that stimulate gamma delta T cells and optionally chemotherapeutic agents that stabilize CLDN18.2 expression. This synergistic treatment approach leverages the antibody's ability to bind CLDN18.2, a gastric cancer antigen, with agents that activate gamma delta T cells and potentially increase CLDN18.2 expression on cancer cells. The combination improves cancer cell killing by the antibody and immune response.
