ABSTRACT

This is a summary of the original article ?Overall survival with osimertinib in resected EGFR-mutated NSCLC.Ë® Osimertinib blocks the activity of the epidermal growth factor receptor (EGFR) on cancer cells, causing cancer cell death and tumor shrinkage, and is an effective treatment for EGFR-mutated non-small cell lung cancer (NSCLC). The ADAURA study assessed the effects of osimertinib versus placebo in patients with EGFR-mutated (exon 19 deletion or L858R) early stage (IB-IIIA) NSCLC removed by surgery (resected). Previous results from ADAURA demonstrated that patients treated with osimertinib stayed alive and cancer-free (disease-free survival) significantly longer than patients who received placebo. Recent data showed the overall length of time patients were alive after starting treatment (overall survival). In both the primary stage II-IIIA and overall stage IB-IIIA populations, patients in the osimertinib group had a significant 51% reduction in the risk of death compared with the placebo group. The data demonstrated that osimertinib after surgery significantly improved overall survival in patients with resected, EGFR-mutated, stage IB-IIIA NSCLC.

ABSTRACT

BACKGROUND: Among patients with resected, epidermal growth factor receptor (EGFR)-mutated, stage IB to IIIA non-small-cell lung cancer (NSCLC), adjuvant osimertinib therapy, with or without previous adjuvant chemotherapy, resulted in significantly longer disease-free survival than placebo in the ADAURA trial. We report the results of the planned final analysis of overall survival. METHODS: In this phase 3, double-blind trial, we randomly assigned eligible patients in a 1:1 ratio to receive osimertinib (80 mg once daily) or placebo until disease recurrence was observed, the trial regimen was completed (3 years), or a discontinuation criterion was met. The primary end point was investigator-assessed disease-free survival among patients with stage II to IIIA disease. Secondary end points included disease-free survival among patients with stage IB to IIIA disease, overall survival, and safety. RESULTS: Of 682 patients who underwent randomization, 339 received osimertinib and 343 received placebo. Among patients with stage II to IIIA disease, the 5-year overall survival was 85% in the osimertinib group and 73% in the placebo group (overall hazard ratio for death, 0.49; 95.03% confidence interval [CI], 0.33 to 0.73; P<0.001). In the overall population (patients with stage IB to IIIA disease), the 5-year overall survival was 88% in the osimertinib group and 78% in the placebo group (overall hazard ratio for death, 0.49; 95.03% CI, 0.34 to 0.70; P<0.001). One new serious adverse event, pneumonia related to coronavirus disease 2019, was reported after the previously published data-cutoff date (the event was not considered by the investigator to be related to the trial regimen, and the patient fully recovered). Adjuvant osimertinib had a safety profile consistent with that in the primary analysis. CONCLUSIONS: Adjuvant osimertinib provided a significant overall survival benefit among patients with completely resected, EGFR-mutated, stage IB to IIIA NSCLC.
