Everest Medicines has announced that the first patient has been dosed in a Phase Ib/II study evaluating FGF401 in combination with PD-1 inhibitor, pembrolizumab, in patients with advanced solid tumors, such as hepatocellular carcinoma.
The three dihydroxystilbenes in this study inhibited colon carcinogenesis and tumor growth as well as increases in colon IL-1β, IL-6, MCP-1, and PD-1 levels in AOM/DDS-treated mice in vivo. The three dihydroxystilbenes also suppressed COX-2 expression in colon tumors in vivo and inhibited PD-1 elevations in M2-THP-1 macrophages in vitro.

Scientists showed that PD-L1 regulated lung cancer growth and progression by targeting the WIP and β-catenin signaling. Overexpression of PD-L1 promoted tumor cell growth, migration and invasion in lung cancer cells, whereas PD-L1 knockdown had the opposite effects.
