    Peripheral Biomarker Analysis of T cell-mediated Collagen Remodeling Correlates with Tumor Responses in a Phase IIa trial of vaccine immunotherapeutic candidate (VBI-1901) (SNO 2023)
    The peripheral C4G biomarker targets granzyme-B-cleaved type IV collagen, which is associated with T cell infiltration and has previously been shown to potentially identify recurrent GBM patients responding to nivolumab and bevacizumab. Evaluating the balance of immune infiltration vs. tumor cell growth in patients with brain tumors is challenging and these data suggest a means of assessing this dynamic using a peripheral biomarker. These data may be particularly useful in discerning pseudoprogression associated with T cell infiltration from tumor progression.
