Surface Oncology To Collaborate With Roche On Immuno-Oncology Study In Friday pre-market trade, SURF was trading at $9.41 up $0.35 or 3.86%. Surface Oncology noted that the collaboration leverages Roche's deep experience in hepatocellular carcinoma and Surface's commitment to rationally and rapidly develop SRF388, a first-in-class antibody against IL-27, to provide meaningful benefit to patients with liver cancer. Atezolizumab plus bevacizumab has been shown to significantly improve overall survival and, as reflected in many global clinical practice guidelines, is the new standard of care for unresectable or metastatic HCC. Evolving preclinical and epidemiologic data suggest a significant role for the immunosuppressive cytokine IL-27 in HCC and in resistance to PD-1 pathway blockade.
