Although all tumor-bearing animals receiving combined DC–Lysate vaccines required euthanasia by day 75, 70% of mice in cohorts treated with DC–Pool Peptide vaccines + CKM + anti-PD-L1 were alive on study day 75 (vs. 20% and 0% alive in the DC–Pool Peptide + CKM only and DC–Pool Peptide + anti-PD-L1 only vaccine cohorts, respectively; both p < 0.05). Here, CKM is linked to neoplasm.
