Exploratory analysis revealed that PFS benefits from aumolertinib plus apatinib predominantly in those with TP53 mutations. As an infusion-free option, aumolertinib plus apatinib demonstrated PFS benefits with manageable safety in patients with untreated, EGFR-mutant, advanced NSCLC.

Here, we describe a case of early-stage non-small cell lung cancer (NSCLC) harboring a G719C+S768I compound mutation that achieved complete remission following treatment with furmonertinib. These findings suggest that furmonertinib may represent a promising therapeutic option to improve cure rates in this subset of patients.

The patient showed no meaningful response to EGFR-tyrosine kinase inhibitors (EGFR-TKIs), including the first-generation (Icotinib), the second-generation (Afatinib) and the third-generation (Aumolertinib). Trophoblast cell surface antigen 2-antibody-drug conjugate (TROP2-ADC) and immune checkpoint inhibitors (ICIs) combined with Bevacizumab also resulted in limited efficacy. Based on the clinical features and treatment response of this case, we reviewed the published literature about the pathological characteristics, mutational landscape, and current therapeutic approaches for PEAC, with a particular focus on the therapeutic challenges and future research directions for EGFR-mutant PEAC, aiming to provide insights for clinical practice and further studies..

We also explored clinical phosEGFR reduction induced by the 3rd generation TKI osimertinib, suggesting that limited target engagement may explain modest response achieved in EGFR Exon20Ins at the clinically investigated doses. The developed model is a valuable tool to understand the impact of kinetic characteristics on phosEGFR reduction and related efficacy, select a target engagement-based criterion for therapeutic dose predictions, and provide interpretation and insights on observed clinical efficacy of irreversible inhibitors in EGFR Exon20Ins.

The efficacy of TKIs was consistent across SQC forms (including de novo or adenocarcinoma-transformed cases) and EGFR mutation types. The findings indicate that, compared with early-generation TKIs, third-generation TKIs are effective against de novo SQCs and should be considered a plausible treatment option for transformed SQCs.

Disruption of ligand binding domain of EGFR by sequential knock in CRISPR/Cas9 genome editing altered subcellular localization and phosphorylation of EGFR in cervical cancer cells. The results presented here provide insights that may accelerate the development of CRISPR/Cas9-based therapies for EGFR-dependent cancers and reinforce the importance of thorough evaluation of CRISPR/Cas9-generated phenotypes.

For classical EGFR mutations such as exon 19 deletion and exon 21 L858R mutation, combination strategies in the first-line setting, based on the results of the MARIPOSA (lazertinib and amivantamab) and FLAURA 2 (platinum-based doublet chemotherapy and osimertinib) trials, provide promising outcomes. Optimising the treatment sequence in advanced EGFR-mutated NSCLC is crucial to ensure the best survival outcomes along with the best treatment tolerance and quality of life. Predictive biomarkers are strongly needed as well as biomarker-based escalation and de-escalation clinical trials.
