This work demonstrated for the first time that Endostar enhanced the antitumor efficacy of Osimertinib, offering a potential therapeutic approach for patients harboring triple mutations.

Our analysis represents the largest study to date assessing the prevalence of germline EGFR mutations from both patients with lung cancer and unselected cohorts of individuals and presents evidence for increased prevalence of EGFR T790M mutations within the Southeastern United States. Given the high prevalence and documented hereditary risk of germline EGFR mutations, future studies investigating the role of familial testing and screening in these individuals is warranted.
After resolution with corticosteroids, treatment was switched to afatinib. This study highlights the heterogeneous approaches to OILI and the potential feasibility of rechallenge in selected patients. Given the expanding osimertinib use for early and advanced stage NSCLC, further research is warranted to refine treatment decisions and optimize patient safety.

Compound 19 was the most potent inhibitor of WT EGFR (3.0 nM) observed, more potent than the EGFR WT inhibitor Erlotinib (5.9 nM). Compounds 48 and 49 demonstrated better activity for the double-mutant EGFR (3.0 & 2.0 nM, respectively) than Osimertinib (12.8 nM)...Kinetic evaluation of 48 (propenamide moiety) vs 49 (acrylamide electrophile) confirms kinact/Ki values consistent with a covalent mode of action for the latter, but not the former. 2009 Elsevier Ltd.
The addition of osimertinib to curative-intent strategies have demonstrated improvements in disease-free survival and overall survival (OS) as adjuvant therapy in resected stage IB-IIIa patients, major pathological responses compared to chemotherapy when used as neoadjuvant therapy, and progression-free survival (PFS) compared to placebo when used as consolidation therapy in unresectable stage III patients. Currently, subsequent treatment recommendations include chemotherapy or datopotamab deruxtecan following progression on a third-generation EGFR-TKI combination and amivantamab plus platinum-based chemotherapy following progression on monotherapy. The treatment landscape for NSCLC with common EGFR mutations is rapidly evolving and third-generation EGFR-TKIs play an integral role in both the curative-intent and palliative settings.
