Anti-glypican 3 antibody

Anti-glypican 3 (GPC3) antibody that boosts ADCC/CDC to unlock next-gen liver cancer immunotherapy.

What it is

The antibody binds a defined region of glypican-3 (GPC3) on tumor cells, triggering immune killing via antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). Its technical edge is that it reports higher ADCC and CDC activity than conventional anti-GPC3 antibodies, improving the “kill” signal delivered to immune effector cells. Previously, therapeutic and diagnostic development using this specific anti-GPC3 binding/engineered antibody required patent licensing from the assignee.

What you could build

Develop GPC3-targeted antibody-based diagnostics or next-gen ADC-agnostic immunotherapies for hepatocellular carcinoma without paying royalties.
