Provided is an anticancer agent which comprises an anti-PD-1 antibody or an anti-PD-L1 antibody as an active ingredient, functioning to reverse the unresponsiveness of iNKT cells in which anergy has been induced by administration with an iNKT cell ligand. The anti-PD-1 or anti-PD-L1 antibody blocks the PD-1 / PD-L1-mediated signaling pathway not only to prevent the iNKT cell ligand-induced iNKT cell anergy, but also to reverse the unresponsiveness of already anergic iNKT cells to produce cytokines. In addition, the anti-PD1 or anti-PD-L1 antibody ensures the potent anti-tumor activity of iNKT cells as demonstrated by a significant reduction in the number of metastatic nodules in B16F10 melanoma metastasis models in vivo. Collectively, the anticancer agent can be very useful in the treatment of cancer, particularly metastatic cancer.

Cancer immunotherapy

We formulated multiple TLR agonists into GVAX (lethally irradiated tumor cell vaccines engineered to secrete GM-CSF). Specifically, GLA and R848, TLR4 and TLR7 / 8 agonists found to be safe in patients, were formulated with GVAX (TEGVAX—for TLR agonists enhanced GVAX), and this formulation was effective in producing anti-tumor responses in 3 different preclinical models, including palpable B16. These anti-tumor responses were correlated with increased CD4 and CD8 T-cells that can secrete IFNγ circulating in the tumor microenvironment as well as significantly higher level of p15E specific CTL mediated cell killing in mice treated with TEGVAX in comparison to controls. When combined with anti-PD-1 antibody, TEGVAX was able to induce regression of established B16 tumors.
