EGFR exon 20 mutation

The combination of osimertinib and crizotinib resulted in a marked clinical and metabolic response, was well tolerated, and the patient remained in remission. This rare case highlights that acquired CD74-ROS1 fusions may contribute to osimertinib resistance and suggests that combination targeted therapy may represent a potential therapeutic approach in selected patients.

All were grade one to two, with no discontinuations due to toxicity. This small case series describes preliminary antitumor activity and a manageable safety profile with the quadruplet regimen in EGFR ex20ins-mutated NSCLC, warranting further investigation.

The worse prognoses and limited treatment options for patients with advanced NSCLC harboring EGFR ex20ins from the Taiwan real-world setting indicate an urgent need for effective treatment for this population. This study showed that amivantamab, when administrated in the CHRYSALIS trial setting, represents a promising treatment option for patients compared to current real-world therapies.

This report offers evidence that Osimertinib may serve as a treatment option for patients with EGFR exon20 p.A763V mutation. In addition, dynamic spatiotemporal heterogeneity of lung cancer cells should be considered when treating patients with EGFR-positive NSCLC.

Co-administration of YFSJ and gefitinib suppresses the growth and migration of NSCLC. ANKRD1 may be a potential biomarker for EGFR exon 20 mutation-driven resistance. This therapy reduces resistance to first-generation EGFR-TKIs by blocking YAP/ANKRD1 axis to suppress cell proliferation and promoting apoptosis. Based on our previous clinical investigations and the present preclinical findings, YFSJ-particularly in combination with gefitinib-may represent a novel therapeutic strategy and warrants further exploration for the treatment of NSCLC resistant to EGFR exon 20 mutations.

This patent describes novel prop-2-ynamide-derived epidermal growth factor receptor (EGFR) inhibitors, which selectively target EGFR exon20 insertion mutations. These EGFR inhibitors exhibit therapeutic potential for the treatment of nonsmall cell lung cancer (NSCLC) and other malignancies driven by EGFR mutations.

The management of human epidermal growth factor receptor 2 (HER2)-mutant non-small cell lung cancer (NSCLC) remains a significant clinical challenge, with limited effective and accessible treatment options beyond antibody-drug conjugates such as trastuzumab deruxtecan (T-DXd)...Following chemotherapy and sintilimab failure in August 2025 due to progressive disease, furmonertinib rechallenge at 160 mg/day again induced a response within 5 days, with no grade ≥3 adverse events...The structural homology between HER2 p.Y772_A775dup and EGFR exon 20 "near-loop" insertions may facilitate TKI binding. Furmonertinib emerges as a potential, cost-effective oral therapeutic alternative for this patient population, especially when standard therapies are not feasible, warranting further prospective investigation.
