Overview

A combination of **tunlametinib**, a selective and potent MEK1/2 inhibitor developed for cancers with RAS/RAF mutations, and a **PD-1 monoclonal antibody** (immune checkpoint inhibitor), used in investigational settings for the treatment of cancers such as NRAS-mutant advanced melanoma and thyroid cancer. Tunlametinib targets the MAPK signaling pathway, while PD-1 monoclonal antibodies block the PD-1/PD-L1 interaction, thereby enhancing anti-tumor immune responses. The combination leverages the tumor-intrinsic cytostatic/cytotoxic mechanism of MEK inhibition with the immune-mediated tumor clearance promoted by PD-1 blockade. This combination is currently being evaluated in clinical trials[1][5][7][9].
