GMB-475, a BCR-ABL1 Inhibitor Based on PROTAC, Has the Potential to Overcome BCR-ABL1-Dependent Drug Resistance. In both human CML K562 cells and murine Ba/F3 cells expressing BCR-ABL1, GMB-475 induces rapid proteasomal degradation and inhibition of downstream biomarkers. Notably, GMB-475 inhibits the proliferation of certain clinically relevant BCR-ABL1 kinase domain point mutants. GMB-475 reduces viability and increases apoptosis in primary chronic myeloid leukemia CD34+ cells, with no effect on healthy CD34+ cells. Furthermore, GMB-475 degrades BCR-ABL1 and reduces cell viability in primary chronic myeloid leukemia stem cells.
