We are a clinical-stage biopharmaceutical company designing and developing novel small molecule, targeted oncology therapies to address key limitations of existing therapies and improve the lives of patients. Our internally developed and wholly owned pipeline of next-generation tyrosine kinase inhibitors (TKIs) targets numerous genetic drivers of cancer in both TKI-naïve and TKI-pretreated patients. The pervasive challenges of intrinsic and acquired treatment resistance often limit the response rate and durability of existing therapies. One of these challenges is the emergence of solvent front mutations, which are a common cause of acquired resistance to currently approved therapies for ROS1, TRK and ALK kinases. We have developed a macrocycle platform enabling us to design proprietary small, compact TKIs with rigid three-dimensional structures that potentially bind to their targets with greater precision and affinity than other kinase inhibitors. We believe our macrocycle platform will generate TKIs that are potentially best-in-class. Our lead drug candidate, repotrectinib (TPX-0005), is being evaluated in an ongoing Phase 1/2 trial called TRIDENT-1 for the treatment of patients with ROS1+ advanced non-small-cell lung cancer (NSCLC) and patients with ROS1+, NTRK+ or ALK+ advanced solid tumors.
