BACKGROUND: Neoadjuvant nivolumab plus chemotherapy significantly improved pathological complete response and event-free survival in patients with resectable non-small-cell lung cancer (NSCLC) in a phase 3 trial. Data are needed on overall survival. METHODS: In this open-label, phase 3 trial, patients with stage IB to IIIA resectable NSCLC were randomly assigned to receive nivolumab plus chemotherapy or chemotherapy alone for three cycles, followed by surgery. The primary end points were event-free survival and pathological complete response. Here, we report the results of the planned analysis of overall survival. RESULTS: A total of 358 patients were concurrently assigned to receive nivolumab plus chemotherapy (179 patients) or chemotherapy alone (179 patients). The final analysis of overall survival significantly favored neoadjuvant nivolumab plus chemotherapy over chemotherapy (hazard ratio for death, 0.72; 95% confidence interval [CI], 0.523 to 0.998; P = 0.048). At a median follow-up of 68.4 months, the 5-year overall survival was 65.4% with nivolumab plus chemotherapy and 55.0% with chemotherapy alone, with consistency across most subgroups. In exploratory analyses, the 5-year overall survival in the nivolumab-plus-chemotherapy group was 95.3% (95% CI, 82.7 to 98.8) among the patients with a pathological complete response and 55.7% (95% CI, 46.9 to 63.7) among those without such a response; survival was 75.0% among the patients with presurgery clearance of circulating tumor DNA (ctDNA) and 52.6% among those without such clearance. No new safety signals were observed. CONCLUSIONS: Three cycles of neoadjuvant nivolumab plus chemotherapy significantly improved overall survival among patients with resectable NSCLC as compared with chemotherapy alone.

BACKGROUND: (epidermal growth factor receptor)-mutated advanced non-small-cell lung cancer (NSCLC) was significantly improved with amivantamab-lazertinib as compared with osimertinib. Results of the protocol-specified final overall survival analysis in this trial have not been reported. METHODS: -mutated (exon 19 deletion or L858R substitution), locally advanced or metastatic NSCLC to receive amivantamab-lazertinib, osimertinib, or lazertinib. Overall survival (assessed in an analysis of the time from randomization to death from any cause) in the amivantamab-lazertinib group as compared with the osimertinib group was a key secondary end point. Additional end points included safety. RESULTS: A total of 429 participants each were assigned to receive amivantamab-lazertinib or osimertinib. Over a median follow-up of 37.8 months, amivantamab-lazertinib led to significantly longer overall survival than osimertinib (hazard ratio for death, 0.75; 95% confidence interval, 0.61 to 0.92; P = 0.005); 3-year overall survival was 60% and 51%, respectively. At the clinical cutoff date, 38% of participants in the amivantamab-lazertinib group and 28% in the osimertinib group were still receiving the assigned treatment. Adverse events of grade 3 or higher were more common with amivantamab-lazertinib (in 80% of participants) than with osimertinib (in 52%), particularly skin-related events, venous thromboembolism, and infusion-related events; these findings were consistent with the established safety profile of each treatment. No new safety signals were observed with additional follow-up. CONCLUSIONS: -mutated advanced NSCLC than osimertinib but was associated with an increased risk of adverse events of grade 3 or higher.

BACKGROUND: gene mutations occur in 2 to 4% of patients with non-small-cell lung cancer (NSCLC). Sevabertinib is an oral, reversible tyrosine kinase inhibitor that has shown anti-HER2 activity in preclinical models. METHODS: -mutant NSCLC. Three cohorts were defined according to previous therapy: cohort D comprised previously treated patients who had not received HER2-targeted therapy; cohort E, patients who had previously received HER2-directed antibody-drug conjugates; and cohort F, patients who had not previously received treatment. The primary end point was an objective response, as assessed by blinded independent central review. Secondary end points were duration of response and progression-free survival. RESULTS: A total of 209 patients received sevabertinib (as of June 27, 2025, the data-cutoff date); the median duration of follow-up was 13.8 months in cohort D, 11.7 months in cohort E, and 9.9 months in cohort F. Among 81 patients in cohort D, an objective response was observed in 64% (95% confidence interval [CI], 53 to 75); the median duration of response was 9.2 months (95% CI, 6.3 to 13.5), and the median progression-free survival was 8.3 months (95% CI, 6.9 to 12.3). Among 55 patients in cohort E, an objective response was observed in 38% (95% CI, 25 to 52); the median duration of response was 8.5 months, and the median progression-free survival was 5.5 months. Among 73 patients in cohort F, an objective response was observed in 71% (95% CI, 59 to 81), and the median duration of response was 11.0 months; data on progression-free survival were immature. Grade 3 or higher drug-related adverse events occurred in 31% of the patients. The most common adverse event was diarrhea (in 84 to 91%), with diarrhea of grade 3 or higher occurring in 5 to 23%. Treatment was discontinued by 3% of the patients owing to drug-related adverse events. CONCLUSIONS: -mutant NSCLC. Diarrhea was the most common adverse event.

Lung cancer is the most prevalent malignant tumour in the Asia-Pacific region.Non-small cell lung cancer (NSCLC) accounts for approximately 85% of lung cancers.Among these, the rate of EGFR mutations in Asian patients with lung adenocarcinoma is 40-60%.Third-generation EGFR tyrosine kinase inhibitors (EGFR-TKIs) have improved the clinical management of NSCLC with EGFR mutations, but resistance to these drugs remains a significant challenge.Despite numerous ongoing studies, there is no standardized consensus on managing resistance to third-generation EGFR-TKIs.This consensus integrates international guidelines on EGFR-TKI management, findings from clinical studies, and experiences from the Asia-Pacific region in addressing post-resistance.Detailed recommendations are provided for classification and progression patterns, clinical testing, and post-resistance treatment strategies related to third-generation EGFR-TKI resistance.The aim of these recommendations is to offer reference opinions for the standardized management of patients exhibiting resistance to third-generation EGFR-TKIs in clinical practice.
