GlaxoSmithKline is stumping up $85 million upfront and up to an extra $730 million in biobucks for Surface Oncology’s early-stage antibody asset.

The drug the U.K. pharma is betting on, known as SRF813, is a fully human, IgG1 antibody targeting PVRIG (also known as CD112R), an inhibitory protein expressed on natural killer cells and T cells.

In preclinical tests, Surface Oncology says, SRF813 has shown the “potential to elicit a strong anti-tumor response and promote immunological memory.” It’s still only in IND-enabling studies, but the company has an IND planned for next year.
