In a posthoc, exploratory analysis in the SAVANNAH clinical trial, QCS was performed on centrally stained MET IHC slides from patients treated with savolitinib 300mg QD + osimertinib 80mg QD (NCT03778229)….Improved efficacy in patients with high biomarker tumors (IHC90+ and/or FISH10+) as determined by manual score was recently reported (WCLC2022). Consistent with manual scores, patients with QCS derived BM+ tumors had a mPFS of 7.8m (95% CI: 5.8-10.4) compared to BM- tumors 2.9m (95%CI: 2.6-4.2)....In summary, we report the development and application of an image-analysis based computational pathology method for quantification of MET expression.
