Under the terms of the agreement, GSK will be granted an exclusive global license for the research, development, manufacturing, and commercialisation of a pre-clinical bispecific antibody that crosslinks tumour cells and T cells by targeting a tumour-associated antigen (TAA) on tumour cells and CD3 expression on T cells and up to three additional pre-clinical TCE antibodies currently at an earlier discovery stage.

WuXi Biologics will receive a $40 million upfront payment and up to $1.46 billion in additional payments for research, development, regulatory and commercial milestones across the four TCE antibodies. WuXi Biologics is also eligible to receive tiered royalties on net sales.
