Overall Survival with Osimertinib in Untreated, EGFR -Mutated Advanced NSCLC
Phase 2 or 3 results paper on Osimertinib in Non-small-cell lung cancer, in New England Journal of Medicine (2020), one of the most cited Europe PMC records with Osimertinib in its title.
Overview
Background: Osimertinib is a third-generation, irreversible tyrosine kinase inhibitor of the epidermal growth factor receptor (EGFR-TKI) that selectively inhibits both EGFR-TKI-sensitizing and EGFR T790M resistance mutations. A phase 3 trial compared first-line osimertinib with other EGFR-TKIs in patients with EGFR mutation-positive advanced non-small-cell lung cancer (NSCLC). The trial showed longer progression-free survival with osimertinib than with the comparator EGFR-TKIs (hazard ratio for disease progression or death, 0.46). Data from the final analysis of overall survival have not been reported.
Methods: In this trial, we randomly assigned 556 patients with previously untreated advanced NSCLC with an EGFR mutation (exon 19 deletion or L858R allele) in a 1:1 ratio to receive either osimertinib (80 mg once daily) or one of two other EGFR-TKIs (gefitinib at a dose of 250 mg once daily or erlotinib at a dose of 150 mg once daily, with patients receiving these drugs combined in a single comparator group). Overall survival was a secondary end point.
Results: The median overall survival was 38.6 months (95% confidence interval [CI], 34.5 to 41.8) in the osimertinib group and 31.8 months (95% CI, 26.6 to 36.0) in the comparator group (hazard ratio for death, 0.80; 95.05% CI, 0.64 to 1.00; P = 0.046). At 3 years, 79 of 279 patients (28%) in the osimertinib group and 26 of 277 (9%) in the comparator group were continuing to receive a trial regimen; the median exposure was 20.7 months and 11.5 months, respectively. Adverse events of grade 3 or higher were reported in 42% of the patients in the osimertinib group and in 47% of those in the comparator group.
Conclusions: Among patients with previously untreated advanced NSCLC with an EGFR mutation, those who received osimertinib had longer overall survival than those who received a comparator EGFR-TKI. The safety profile for osimertinib was similar to that of the comparator EGFR-TKIs, despite a longer duration of exposure in the osimertinib group.

Indexed on Europe PMC as PubMed record 31751012 (DOI 10.1056/nejmoa1913662). Its title names Osimertinib and its text names Non-small-cell lung cancer; PubMed types it as a clinical trial report (Clinical Trial, Phase III, Comparative Study, Research Support, Non-U.S. Gov't, Multicenter Study, Randomized Controlled Trial). It was matched automatically to the idea "Treat brain metastases as a disease with its own trials programme" and no figure has been checked by an editor.
One of the most cited trial reports Europe PMC returns for Osimertinib in Non-small-cell lung cancer, so it is a natural first reading for anyone weighing the idea it is linked from. The record was linked automatically by title and abstract; read the abstract above and the paper itself before relying on any figure.
- Matched by Osimertinib in the title and Non-small-cell lung cancer in the title or abstract of the Europe PMC record; the summary reproduces the record's abstract and no figure has been verified against the full paper.
- Chosen as a phase 2 or 3 report by the record's publication type or its own wording, not by reading the paper.
