Selpercatinib mitigates cancer cachexia independent of anti-tumor activity in the HT1080 tumor model.

ABSTRACT: Anorexia is a major cause of cancer cachexia and is induced by growth differentiation factor-15 (GDF15), which activates the rearranged during transfection (RET) protein tyrosine kinase in the hindbrain through GDF family receptor α-like (GFRAL), raising the possibility of targeting RET for cancer cachexia treatment. RET-altered cancer patients treated with RET-selective kinase inhibitors gain weight, however, it is unclear whether this results from tumor regression that improves the overall health of patients. Thus, the potential of using a RET inhibitor to address cancer cachexia remains unknown. Using a RET-negative tumor model, we evaluated the activity of the RET-selective inhibitor selpercatinib (LOXO-292) against cancer cachexia. In tumor-bearing animals, selpercatinib significantly
