SHP2 INHIBITOR SITNEPROTAFIB COMBINATION THERAPY DATA PUBLISHED IN ACADEMIC JOURNAL (HKEXnews) - "The article details in vitro/in vivo preclinical data and representative cases of patients on the SHP2 inhibitor in combination therapies targeting the RTK/RAS/MAPK pathway and PD-1 blockade therapies. The study demonstrates that sitneprotafib significantly enhances the anti-tumor activity of the KRAS G12C inhibitor glecirasib in both treatment-naïve and resistant models. Combination of sitneprotafib with MEK inhibitors significantly delayed RTK signaling reactivation and enhanced tumor growth inhibition in KRAS-mutated cancer models. Sitneprotafib-osimertinib combination exhibited great efficacy in osimertinib-resistant non-small cell lung cancer (NSCLC) models."
