About Dubermatinib (TP-0903)

Dubermatinib is an investigational oral AXL receptor tyrosine kinase (RTK) inhibitor under evaluation in a Phase 1a/b study in patients with advanced solid tumors (NCT02729298) and an ongoing study in collaboration with the Leukemia & Lymphoma Society as part of the Beat AML Clinical Trial (NCT03013998). SDP Oncology is exploring parallel clinical development paths for dubermatinib in both solid and hematologic malignancies.

About AXL Kinase

AXL belongs to the TAM (Tyro3, AXL and Mer) family of receptor tyrosine kinases and is overexpressed in many human cancers.¹ It plays a key role in tumor cell proliferation, survival, metastasis, cellular adhesion, and avoidance of the immune response. The overexpression of AXL is associated with a poor patient prognosis and drug resistance.²
