Conclusions: LUX-Lung 3 & 6 Trial Data LUX-Lung 3 and LUX-Lung 6 are the largest and most robust prospective randomised trials in EGFR mutation–positive NSCLC LUX-Lung 3 met its primary end point of PFS (independent review) –Median PFS of 11.1 months for afatinib vs 6.9 months for chemotherapy in overall study population; HR=0.58 (95% CI, ); P<0.001 –Consistent efficacy in all relevant subgroups –Significant improvement in response rates and disease control rates LUX-Lung 6 consistently confirmed the results of LUX-Lung 3 and met its primary end point of PFS (independent review) –Median PFS of 11.0 months for afatinib vs 5.9 months for chemotherapy in overall study population; HR=0.28 (95% CI, ); P< –Consistent efficacy in all relevant subgroups –Significant improvement in response rates and disease control rates PFS improvement with first-line afatinib was associated with a significant improvement in patient-reported outcomes and the QoL in both trials –Afatinib demonstrated a significant delay in time to deterioration for cough and dyspnoea in both LUX-Lung 3 and 6 trials and also delayed pain in LUX-Lung 6 trial
Conclusions: LUX-Lung 3 & 6 Trial Data (cont‘d) First-line afatinib significantly improved OS vs chemotherapy in EGFR Del19 patients in two randomized trials –LUX-Lung 3: median 33.3 vs 21.1 months, HR=0.54, p= –LUX-Lung 6: median 31.4 vs 18.4 months, HR=0.64, p= No significant difference in OS of patients with L858R mutations, individually, or in exploratory combined analysis –Benefit in PFS, ORR and PRO previously shown Del19 and L858R patients are two distinct populations and should be studied separately in the future An OS benefit with afatinib in patients with common mutations (Del19/L858R) in the exploratory combined analysis Diarrhoea and rash were the most frequent AEs; manageable with low treatment discontinuation rate First-line afatinib should be the standard of care for EGFR Del19 patients and remains a treatment option for EGFR L858R patients
