AXL Inhibitors: Status of Clinical Development

Curr Oncol Rep. 2023 May;25(5):521-529. doi: 10.1007/s11912-023-01392-7. Epub 2023 Mar 15.

Abstract

Purpose of review: The AXL signaling pathway is associated with tumor growth as well as poor prognosis in cancer. Here, we highlight recent strategies for targeting AXL in the treatment of solid and hematological malignancies.

Recent findings: AXL is a key player in survival, metastasis, and therapeutic resistance in many cancers. A range of AXL-targeted therapies, including tyrosine kinase inhibitors, monoclonal antibodies, antibody-drug conjugates, and soluble receptors, have entered clinical development. Notably, AXL inhibitors in combination with immune checkpoint inhibitors demonstrate early promise; however, further understanding of predictive biomarkers and treatment sequencing is necessary. Based on its role in tumor growth and drug resistance, AXL represents a promising therapeutic target in oncology. Results from ongoing clinical trials will provide valuable insights into the role of AXL inhibitors, both as single agents and in combination with other therapies.

Keywords: AXL; Cancer; GAS6/AXL signaling; Novel therapeutics; Targeted therapy.
