Randomized Controlled Trial
Afatinib versus cisplatin plus pemetrexed in Japanese patients with advanced non-small cell lung cancer harboring activating EGFR mutations: Subgroup analysis of LUX-Lung 3.
In LUX-Lung 3, afatinib significantly improved progression-free survival (PFS) versus cisplatin/pemetrexed in EGFR mutation-positive lung adenocarcinoma patients and overall survival (OS) in Del19 patients. Preplanned analyses in Japanese patients from LUX-Lung 3 were performed. Patients were randomized 2:1 to afatinib or cisplatin/pemetrexed, stratified by mutation type (Del19/L858R/Other). ⋯ Following study treatment discontinuation, most patients (93.5%) received subsequent anticancer therapy. The most common treatment-related adverse events were diarrhea, rash/acne, nail effects and stomatitis with afatinib and nausea, decreased appetite, neutropenia, and leukopenia with cisplatin/pemetrexed. Afatinib significantly improved PFS versus cisplatin/pemetrexed in Japanese EGFR mutation-positive lung adenocarcinoma patients and OS in Del19 but not L858R patients (www.clinicaltrials.gov; NCT00949650).
