Tremelimumab, a fully human cytotoxic T-lymphocyte antigen 4 monoclonal antibody, and PF-3512676, a Toll-like receptor-9 agonist, are targeted immune modulators that elicit durable single-agent antitumour activity in advanced cancer. Methods: To determine the maximum tolerated dose (MTD) of these ...
We now report that, similar to the depletion of regulatory T cells (Treg) using anti-CD25, paclitaxel increased the anti-tumor effect of the TLR9 agonist PF-3512676 in a CD8 + T cell-dependent fashion. Paclitaxel treatment decreased Treg numbers in a TLR4-independent fashion, and ...
