(Nasdaq: CADL), a clinical stage biopharmaceutical company developing novel viral immunotherapies, today announced presentation of late-breaking data from a phase 1 mechanistic clinical trial of CAN-2409, Candel’s lead viral immunotherapy in development, in combination with nivolumab and standard of care treatment in patients with high-grade glioma. Data were presented at the 37th Annual Meeting of Society for Immunotherapy of Cancer (SITC) today in Boston. In the trial involving 35 evaluable patients, extensive biomarker analyses demonstrated that the combination of CAN-2409 and nivolumab resulted in a statistically significant expansion of activated tumor-fighting CD4+ and CD8+ T cells effector cells as well as decreased markers of exhaustion on effector cells. Proteomic analysis by OLINK revealed an increase in pro-inflammatory cytokines, including interferon-gamma, the chemokines CXCL9/10 and CXCL11, MCP-1, MCP-3, and granzyme A. Systemic immune activation was observed after the single administration of CAN-2409, prior to initiation of nivolumab (week 3 post treatment). Median overall survival (mOS) for patients with methylated MGMT promoter was 30.6 months for those who underwent gross total resection (GTR) (n=10) and 12.6 months for those who underwent sub-total resection (STR) (n=5). mOS for patients with unmethylated MGMT was 13.2 months (GTR) (n=16) and 15.9 months (STR) (n=4), respectively. “We are encouraged to see strong systemic immune activation after a single administration of CAN-2409 to the resection bed during neurosurgical removal of the tumor combined with nivolumab treatment in one of the most treatment-resistant cancers, high-grade glioma, which ...
