Lirafugratinib retains activity against multiple mutations that confer clinical resistance to pan-FGFR inhibitors. However, diverse resistance mechanisms, including various kinase domain mutations and RTK-MAPK bypass alterations, remain challenges in the treatment of FGFR2-altered tumors, even with selective FGFR2 kinase inhibition.
The compound demonstrated robust tumor growth suppression, favorable pharmacokinetic profile, and pharmacodynamic effects. This study supports the preclinical development of ISM7594 and demonstrates its potential in advancing tissue-agnostic therapy for advanced solid tumors with FGFR2/3 aberrations and mutation resistance.
The subsequent in vitro evaluation of digitoxigenin and oleandrin derivatives 13a, 13g, 15a, and 15gdemonstrated that these four analogs reduced steady-state ATP1A1 levels in T98G cells in the 12-96 nM range. Interestingly, only the oleandrin analog 15g also lowered also steady-state levels of the cellular prion protein (PrPC), the main therapeutic target for the treatment of prion diseases.
