Osimertinib Shows Promise in Treating EGFR-Mutant Lung Cancer
Seoul, Friday, 25 April 2025.
Osimertinib trials reveal improved survival rates for advanced EGFR-mutant NSCLC patients, highlighting significant clinical activity and potential advancement in treatment protocols.
Breakthrough LAURA Trial Results
Recent data from the phase III LAURA trial demonstrates compelling evidence for osimertinib’s efficacy in treating unresectable stage III EGFR-mutated non-small cell lung cancer (NSCLC). The trial revealed a significant improvement in median overall survival, reaching 58.8 months for patients treated with osimertinib compared to 54.1 months with placebo [1]. This marked improvement occurred despite 78% of placebo group patients receiving subsequent osimertinib treatment upon disease progression, highlighting the drug’s robust therapeutic potential.
Advanced Combination Therapies Show Promise
The SAVANNAH trial has unveiled promising results for combination therapy approaches. When osimertinib was paired with savolitinib, a MET tyrosine kinase inhibitor, the combination achieved a remarkable 56% objective response rate in patients with high MET overexpression or amplification [1]. Further advancement comes from the ORCHARD study, where osimertinib combined with Dato-DXd demonstrated significant clinical activity, achieving a 43% response rate at 4 mg/kg dosing and extending median progression-free survival to 11.7 months at 6 mg/kg [2].
Emerging Research and Future Directions
A groundbreaking development is currently underway with the investigation of BMS-986507 in combination with pembrolizumab and osimertinib mesylate for advanced solid tumors [3]. This innovative approach aims to enhance treatment outcomes for patients with EGFR-mutated NSCLC. The treatment landscape continues to evolve, with new data from the ADAURA trial showing impressive disease-free survival rates of 70% at 48 months in the osimertinib group compared to 29% in the placebo group [4].
