Orpathys (savolitinib)

MET amplification alters the balance of EGFR/MET/ERBB3 dimerization, leading to a shift in signaling dependence from EGFR to MET. These findings provide insight into therapeutic strategies for EGFR-mutated NSCLC.

We report a 59-year-old female non-smoker with stage IV EGFR Leu858Arg-mutated lung adenocarcinoma who sequentially received first-line osimertinib (~9 months), second-line osimertinib plus savolitinib for MET amplification (~20 months), third-line platinum-based chemotherapy with local ablative therapy for oligo-progression, and fourth-line docetaxel. This case illustrates that an acquired BRAF fusion may emerge as a potentially targetable bypass alteration in EGFR-mutated MET-amplified NSCLC after progression on combined EGFR-MET inhibition and that the combination of a first-generation EGFR-TKI and a MEK inhibitor can be associated with prolonged systemic disease control. The findings are hypothesis-generating and support the value of CGP at sequential progression points to guide mechanism-based therapy in oncogene-driven NSCLC.

Savolitinib monotherapy showed encouraging antitumor activities and a tolerable safety profile in heavily treated, later-line METamp G/GEJ cancers, supporting further investigation in randomized controlled trials. ClinicalTrials.gov identifier: NCT04923932 .

Following discontinuation of Savolitinib due to drug-induced liver injury, Tislelizumab, previously associated with resistance, was reintroduced as a "rechallenge" successfully re-establishing disease control. Coupled with a systematic review of pertinent literature, this article explores the clinical features, therapeutic challenges, potential resistance mechanisms, and management approaches for such patients. It also outlines future research avenues for combination or sequential therapies, aiming to furnish a more holistic reference for clinical decision-making.

Drug sensitivity analysis indicated that tozasertib, savolitinib, AZD4547, IWP-2, and GSK591 may have potential therapeutic value. Multi-omics analyses revealed that these key genes are regulated by DNA methylation and transcription factor networks. The actin cytoskeleton-based gene signature serves as an independent indicator of poor prognosis and may support precise prognostic assessment and personalized therapeutic strategies for GBM.

This study provides a comprehensive characterization of METΔex14 in NSCLC, revealing its dual role as a primary driver of oncogenesis and a potential resistance mechanism to EGFR/ALK inhibitors. The identification of concurrent genetic alterations and potential resistance mechanisms enhances our molecular understanding of treatment responses. These findings highlight the need for further investigation into targeted therapies that consider the genomic complexity of METΔex14 to improve treatment efficacy and patient outcomes.

OncoPredict suggested higher sensitivity in the high-risk group to 5-fluorouracil, PI3K-AKT-mTOR inhibitors (afuresertib, pictilisib, taselisib, dactolisib), and the MET inhibitor savolitinib. Multi-omic integration of PCD-related genes delineates PCD-driven heterogeneity in AML and yields a robust five-gene prognostic model with therapeutic implications. CORO1A emerges as a potential apoptosis-associated oncogene that promoting AML cell survival.
