"These data further support the growing body of preclinical evidence demonstrating that SRF388 binds to and blocks IL-27 to inhibit downstream signaling events that are important in regulating immune responses in certain tumor microenvironments," said Vito Palombella Ph.D., chief scientific officer. "We look forward to providing an update on our ongoing, open label, Phase 1 clinical trial of SRF388 in advanced solid tumors later this year."

About SRF388:

SRF388 is a fully human anti-IL-27 antibody designed to inhibit the activity of this immunosuppressive cytokine. Surface Oncology has identified particular tumor types, including hepatocellular and renal cell carcinoma, where IL-27 appears to play an important role in the immunosuppressive tumor microenvironment and may contribute to resistance to treatment with checkpoint inhibitors. Furthermore, Surface Oncology has identified a potential biomarker associated with IL-27 that may be useful in helping identify patients most likely to respond to SRF388.
