- Non-clinical findings further support the potential of SRF388 to treat patients suffering from liver cancer -
Researchers found that IL-27 receptor signaling promoted HCC development in mice, and that IL-27 served as an immunological checkpoint that regulates natural killer (NK) cell and innate immune cell activation. The study also demonstrated that pharmacological neutralization of IL-27 using an antibody developed by Surface led to increased NK and innate immune cell activation and reduced HCC development. The study incorporated observations on the effect of IL-27 on several models of HCC development, including a model of non-alcoholic steatohepatitis (NASH), a known risk factor for the development of liver cancer, which is increasing in prevalence.
“The findings published in Cancer Discovery, combined with previously reported translational and early clinical data, support our hypothesis that IL-27 blockade is a promising immunotherapy for patients with cancer,” said
Surface’s lead IL-27 antibody, SRF388, is currently being evaluated in multiple clinical studies, including a randomized Phase 2 trial designed to evaluate its efficacy and safety in combination with atezolizumab plus bevacizumab in patients with first-line advanced or metastatic HCC. SRF388 was granted Orphan Drug designation and Fast Track designation for the treatment of HCC from the FDA.
