LUX-Lung 6 Trial: Afatinib vs Chemotherapy in
EGFR Mutation-Positive NSCLC
• A multicenter, randomized, open-label, phase 3 trial in China, the Republic of Korea,
and Thailand
• Patients with:
–
–
–
–
–
–
Adenocarcinoma of the lung
Presence of EGFR mutation in the tumor tissue
Stage IIIB/IV
No prior treatment with chemotherapy for advanced/metastatic disease
No prior treatment with EGFR inhibitors
Eastern Cooperative Oncology Group performance status 0 or 1
• N = 364
Randomization 2:1
Afatinib
Cisplatin 75 mg/m2 + gemcitabine 1000 mg/m2
40 mg once daily
IV day 1 + day 8, every 3 weeks
Primary endpoint: PFS

LUX-Lung 6 Trial: PFS
• Median PFS by independent review:
– 11.0 months for afatinib arm
– 5.6 months for chemotherapy arm
• 1-year PFS:
– 47% for afatinib arm
– 2% for chemotherapy arm
Wu YL, et al. ASCO 2013. Abstract 8016.
LUX-Lung 6 Trial: Adverse Events
• Most common grade 3 adverse events associated
with afatinib:
– Rash, 14.2%
– Diarrhea, 5.4%
– Stomatitis/mucositis, 5.4%
• Discontinuation rate due to treatment-related
adverse events:
– 5.9% of patients on afatinib
– 39.8% of patients on chemotherapy
– Only 2% of patients on afatinib discontinued due to rash
and none due to diarrhea

LUX-Lung 7 Trial: Afatinib vs Gefitinib
(Irreversible TKI vs Reversible TKI)
• Patients with
–
–
–
–
Advanced adenocarcinoma of the lung
Documented common EGFR mutations (del19 or L858R)
First line (no prior treatment)
Global study: 57 sites (currently recruiting)
• N = 264
Randomization
Afatinib 40 mg
Gefitinib 250 mg
Primary endpoint: PFS and disease control rate at 12 months
ClinicalTrials.gov. NCT01466660.
Take-Home Messages
• Patients must be tested for the EGFR mutation and,
if positive, receive first-line EGFR TKI
• Significant improvements in PFS in first-line therapy
of patients with EGFR mutation-positive NSCLC with
EGFR TKI vs chemotherapy
• Significant improvement in quality-of-life
parameters with EGFR TKI vs chemotherapy
