Conclusions

• CTONG0806 is the first trial to show significant improvement in PFS, DCR and a trend of improving OS with pemetrexed compared with gefitinib in second-line setting for EGFR wild-type advanced non-squamous NSCLC.

• Pemetrexed should be recommended for EGFR wild-type advanced non-squamous NSCLC in second-line treatment due to its good efficacy and tolerability.

• MiR-200c regulated EMT by targeting ZEB1 in NSCLC cell lines

• Ectopic expression of miR-200c resulted in partial restoration of gefitinib sensitivity in NSCLC cell lines

• miR-200c low-expression may be responsible for gefitinib resistance through PI3K/AKT and MEK/ERK pathway

Conclusions-Part1Conclusions-Part2• Our study showed for the first time that miR-200c expression

might be a potent predictive biomarker in EGFR–WT patients receiving EGFR-TKIs treatment.

• EGFR TKIs may be a non-inferior option to second line chemotherapy if EGFR-WT patients with high miR-200c expression were not willing to choose or unable to tolerant chemo drugs.

• miRNAs are stable in serum or plasma, circulating miR-200c could become a non-invasive, blood-based NSCLC biomarker.

• Prospective clinical trials are wanted to confirm the miR-200c as a predicting biomarker in EGFR-WT NSCLC patients.

Summary

• LUME-Lung 1 met its primary endpoint: PFS (HR: 0.79 p=0.0019)

• A significant improvement in OS was demonstrated in patients with adenocarcinoma (OS; HR: 0.83 p=0.0359 median 12.6 vs 10.3 months)

• Patients with a poor prognosis had the highest OS benefit:

– adenocarcinoma histology and time since start of 1st line therapy <9 months (HR: 0.75 p=0.0073 median OS 10.9 vs 7.9 months)

– adenocarcinoma histology with PD as best response to 1st line treatment (HR: 0.62 p=0.0246 median OS 9.8 vs 6.3 months)

– squamous cell histology with a high tumour burden showed a trend towards improved OS (SLD ≥7.5 cm; HR=0.82 p=0.0995 median OS 7.7 vs 6.1 months)

• Nintedanib plus docetaxel had a manageable safety profile with no unexpected safety findings

• Further investigations are warranted to identify molecular and clinical markers for nintedanib benefit in NSCLC including the effects of high tumour burden (squamous) and tumour dynamics (adenocarcinoma)

Page 37: D EPARTMENT OF T HORACIC O NCOLOGY Filippo de Marinis Department of Thoracic Oncology, IEO, Milan, Italy.

Conclusions

• In second-line NSCLC patients, no significant differences in cough, dyspnea or pain were observed in patients receiving nintedanib + docetaxel compared with placebo + docetaxel– there were trends towards improvements in TTD for global health

status/QoL in patients with adenocarcinoma, and for pain in adenocarcinoma patients with a time since start of first-line therapy <9 months

– QoL scores for nausea and vomiting, appetite loss and diarrhea were worsened in patients who received nintedanib + docetaxel compared with those who received placebo + docetaxel

• Overall, PFS was improved in all patients with nintedanib + docetaxel compared with placebo + docetaxel and OS was significantly improved in patients with adenocarcinoma;1 this analysis demonstrates that these improvements were achieved without substantial alterations in self-reported QoL
