Casdozokitug has been shown to boost immune system activation and drive T and NK cell–driven antitumor responses in the tumor microenvironment that IL-27 is known to inhibit, particularly in #HCC and #NSCLC. @DanengLi @cityofhope Read up on IL-27 here:

Preliminary Casdozokitug Activity in HCC Supports Further Exploration of IL-27 as a Treatment Target (OncLive) - "'IL-27 is an immune-modulatory cytokine that's expressed on myeloid cells, including macrophages and dendritic cells, and it plays a role in terms of dampening T-cell and natural killer [NK] effector cell function,' Daneng Li, MD, noted in an interview with OncologyLive during the 2025 American Society of Clinical Oncology Gastrointestinal Cancers Symposium (ASCO GI)."

Results from a phase 2 study of triplet blockade of the IL-27, PD-(L)1, and VEGF pathways with casdozokitug (casdozo, CHS-388) in combination with atezolizumab and bevacizumab in patients with unresectable, locally advanced or metastatic hepatocellular carcinoma (uHCC). (ASCO-GI 2025) - P1, P2 | "Funded by Coherus BioSciences Clinical Trial Registration Number: NCT05359861 Background: Casdozo is the first in class and only clinical-stage IL-27 targeting antibody, which induces increased serum IFN-γ and NK cell gene activation, leading to reversal of IL-27-mediated immune suppression. Triplet blockade of IL-27, PD-(L)1, and VEGF pathways with casdozo/atezo/bev continues to show a manageable safety profile with promising antitumor activity in uHCC that warrants continued exploration. Toxicity was consistent with the known profiles of the agents, with no new safety signals identified. Biomarker analysis to evaluate immune response and associations of IL-27 pathway and clinical outcomes is ongoing."
