What is Resiquimod?

Resiquimod is a small molecule that binds and activates Toll-like receptors 7 and 8, stimulating maturation of antigen-presenting cells such as dendritic cells and the production of pro-inflammatory cytokines. It is being studied in solid tumors, including pancreatic cancer, non-small cell lung cancer, melanoma, bladder cancer and triple negative breast cancer.
