Description
Batiraxcept (AVB-500; AVB-S6-500) is a selective, soluble AXL receptor and GAS6 inhibitor that targets the GAS6-AXL signaling axis. Batiraxcept is orally inactive and does not cross the blood-brain barrier. Batiraxcept competitively binds to GAS6 ((KD <1 nM), preventing its interaction with the AXL receptor tyrosine kinase, thereby inhibiting downstream PI3K/AKT and MAPK signaling pathways, reducing tumor cell glycolysis, angiogenesis, and metastatic potential. Batiraxcept has demonstrated antitumor activity in preclinical models of endometrial, cholangiocarcinoma, and ovarian cancer by inhibiting tumor growth, invasion, and metastasis[1][2][3]
