Combination tumor immunotherapy

Abstract:

Provided are methods for treating cancer using local administration of certain CpG oligonucleotides (CpG ODN) and systemic administration of a checkpoint inhibitor such as an anti-PD-1 antibody, an anti-PD-L1 antibody, and/or an anti-CTLA-4 antibody. In preferred embodiments, the CpG ODN are selected based on their propensity to induce high amounts of interferon alpha (IFN-.alpha.) and T-cell activation relative to interleukin-10 (IL-10) and B-cell activation. In certain embodiments, the methods further include pretreatment with radiotherapy, to potentiate the combination immunotherapy.
