As many cancers progress to more aggressive disease states, the tumor suppressor arm of TGFβ signaling is lost and, instead, tumor cells proliferate. In contrast, TGFβ overexpression in advanced disease enhances tumor growth, suppresses the immune system, and exacerbates invasive and metastatic tumor cell behavior.3 TGFβ worsens immunosuppression by inhibiting cytotoxic cells such as CD8+ CTLs and NK cells and enhancing suppressive immune cells called T regulatory cells and myeloid-derived suppressor cells.2 Galunisertib (LY2157299 monohydrate) is a small molecule that has been shown in vitro to block TGFβ signaling.4-7 Clinical Development Galunisertib is being investigated in phase I clinical trials, including combination clinical trials in immuno-oncology, and in clinical trials in patients with hepatocellular carcinoma and pancreatic cancer.
