About Bemcentinib

Bemcentinib is a potentially first-in-class, potent and highly selective inhibitor of the tyrosine kinase AXL. Extensive studies confirm the ability to combine bemcentinib with immune checkpoint inhibitors, chemotherapies and targeted therapies with the goal of improving a patient's immune response and delaying the development of chemoresistance. Bemcentinib is currently being investigated in combination with immune checkpoint inhibition and chemotherapy in first line NSCLC patients harboring mutations in the STK11 gene, a known prognostic factor of poor response to existing therapies.
