Abstract Text

To compare the efficacy and toxicity of osimertinib versus docetaxel-bevacizumab as third-line treatment in EGFR T790M mutated NSCLC.In this phase 3, open-label, three-center study, we randomly assigned (1:1) previously treated with TKI-chemotherapy or chemotherapy-TKI recurrent or metastatic advanced non-squamous lung cancer patients into two groups. These patients had acquired EGFR T790M resistance mutation confirmed by tumor tissues or serum. One group received oral osimertinib (80 mg/day) and the other group received intravenous infusion docetaxel (75 mg/m2) and bevacizumab (7.5 mg/kg) every 21 days until disease progression, unacceptable toxic effects or patient death. The primary endpoint of this study was progression-free survival (PFS) and the secondary endpoints were response rates, toxicities and overall survival (OS). This trial was registered with ClinicalTrials.gov, number NCT02959749.A total of 147 patients were treated. Among them, 74 were enrolled in the osimertinib group and 73 were in the docetaxel-bevacizumab group. The median progression-free survival was 10.20 months in the osimertinib group versus 2.95 months in the docetaxel-bevacizumab group (hazard ratio 0.23; 95% confidence interval [CI], 0.12-0.38; P < 0.001). The overall response rate in the osimertinib group was significantly better than in the docetaxel-bevacizumab group (61.6%; 95% CI, 55.5-67.7 versus 8.3%; 95% CI, 1.3-15.3; p < 0.001). Because all the progressed patients in the docetaxel-bevacizumab group crossed over to the osimertinib group, there was no significant difference in the median OS between two groups at the time of last follow-up (hazard ratio 0.79; 95% CI, 0.38-1.61; P = .551). The main grade 3 or 4 toxic effects were diarrhea (2.7%) and interstitial lung disease (1.4%) in the osimertinib group and alopecia (15.3%), anorexia (12.5%), neutropenia (9.7%) and nausea (8.3%) in the docetaxel-bevacizumab group.Osimertinib had higher response rate, longer PFS and milder side effects than docetaxel-bevacizumab in third-line therapy in patients with EGFR T790 M positive advanced NSCLC.

Filtering

Case insensitive filtering will display rows if any text in any cell matches the filter term
Use simple literal full or partial string matches
Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
Click on any column header arrows to sort by that column
Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
