Surface Oncology Announces FDA Clearance of IND Application for GSK4381562, a Novel Antibody Targeting PVRIG
Surface to receive $30 million milestone payment upon first patient treated in the Phase 1 study
CAMBRIDGE, Mass., Dec. 01, 2021 (GLOBE NEWSWIRE) -- Surface Oncology (Nasdaq: SURF), a clinical-stage immuno-oncology company developing next-generation immunotherapies that target the tumor microenvironment, today announced that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug Application (IND) for GSK4381562 (formerly SRF813) to proceed into a first-in-human clinical trial. GSK4381562 is a fully human IgG1 antibody targeting PVRIG (also known as CD112R), an inhibitory protein expressed on natural killer cells (NK cells) and T cells.
In December 2020, Surface announced it had entered into an agreement in which GSK exclusively licensed worldwide development and commercial rights to GSK4381562. Surface will receive a $30 million milestone payment in conjunction with the initiation of the first Phase 1 study for GSK4381562 and is eligible to receive an additional $700 million in future milestone payments, as well as be eligible to receive tiered royalties on global net sales.
“GSK4381562 is a differentiated anti-PVRIG antibody and represents a new therapeutic approach designed to enhance NK and T cell activation in the tumor microenvironment,” said Rob Ross, M.D., chief executive officer. “We are pleased to have reached this milestone with our partners at GSK and look forward to continued advancement of this promising program in the clinic.”
GSK4381562 is a fully human, IgG1 antibody targeting PVRIG (also known as CD112R), an inhibitory protein expressed on natural killer cells (NK cells) and T cells. GSK4381562 binds to a distinct epitope on PVRIG and blocks the interaction of PVRIG with CD112, its binding partner that is overexpressed on tumor cells. Preclinically, GSK4381562 promotes the activation of both NK cells and T cells, with the potential to elicit a strong anti-tumor response and promote immunological memory.
