LUX-Lung 1: Key learnings
• Afatinib significantly improved PFS compared to
placebo
– Post erlotinib/gefitinib failure
• EGFR mutation-positive patients do better
– Predictive for afatinib efficacy
– Prognostic (longer OS in the trial population)
• Impact of subsequent therapy on OS
– Was OS an appropriate endpoint for this setting?
LUX-Lung 4: Phase I/II single arm in Japan

Failure of conventional treatment or no therapy of proven efficacy

LUX-LUNG 3:
SUMMARY
LUX-Lung 3: Summary
• LUX-Lung 3 is the largest* global prospective trial in
EGFR mutation-positive lung cancer and the first
using cisplatin and pemetrexed as the comparator
• LUX-Lung 3 met its primary endpoint with median
PFS (independent review):
– Overall population: 11.1 vs. 6.9 months
– Common mutations: 13.6 vs. 6.9 months
– Consistent efficacy in all relevant subgroups
• Afatinib significantly improved rates of response
versus chemotherapy
• Efficacy findings from the Asian subgroup are in line
with those from the overall trial population
*n=345.
Sequist LV, et al. J Clin Oncol 2013 Jul 1; [Epub ahead of print]; Mok T, et al. Presented at the 5th Annual Meeting of Asian Pacific Lung Cancer Congress,
2013. Oral presentation.
LUX-Lung 3: Summary (continued)
• First-line afatinib significantly prolonged PFS,
with associated delay in worsening of lung cancerrelated symptoms and improvement in quality of life
• Safety profile of afatinib consistent with previous
studies
– Overall population: Diarrhoea and rash were the most
frequent AEs; manageable with low treatment
discontinuation rate
– Asian patients: Diarrhoea and rash were the most
frequent AEs; no treatment discontinuations for rash
and only one Asian patient discontinued for diarrhoea

LUX-Lung 6: Summary and conclusions
• In EGFR mutation-positive Asian patients,
afatinib significantly prolonged PFS compared with
gemcitabine/cisplatin
– Median PFS of 11.0 vs. 5.6 months (HR=0.28; p<0.0001)
(independent review)
• PFS benefit was observed across all prespecified
subgroups
• Treatment with afatinib was associated with significant
improvements in ORR, DCR, symptom control and quality
of life compared with chemotherapy
• Safety profile was as expected in both treatment arms
• Afatinib had a more favourable safety profile compared with
chemotherapy
• LUX-Lung 6 is the largest prospective first-line trial in EGFR
mutation-positive lung cancer patients

– Addressing different questions
– Different settings
– Different patient subgroups
– Different combinations
• Afatinib demonstrates efficacy in EGFR mutationpositive NSCLC
– Irrespective of line of treatment
– Irrespective of prior treatment with EGFR-TKIs
