| Description |
Abstract Aberrant activation of tropomyosin receptor kinases (TRKs) is a well-defined oncogenic driver for neurotrophic tropomyosin receptor kinase (NTRK)-fusion cancers, and acquired resistant mutations have emerged with clinical use of the first-generation TRK inhibitors. Here we present BPI-28592, a novel second-generation TRK inhibitor with efficacy against TRK fusion-positive cancers, including those with resistant mutations. Docking simulations indicated no steric hindrance between BPI-28592 and TRK mutants, suggesting its potential to overcome drug resistance. Biochemical assays showed strong inhibition and high selectivity against TRKA, TRKB, and TRKC. The inhibitor significantly reduced cell proliferation and blocked TRK signaling. In vivo studies demonstrated effective tumor suppression in xenograft models harboring TRK fusions with or without resistant mutations. Clinically, BPI-28592 achieved a complete response in a patient with malignant melanoma carrying an AP3S2-NTRK3 fusion (Clinicaltrials. gov identifier: NCT05302843).
