Abstract 2988


The irreversible ErbB family blocker, A, and the reversible EGFR TKI, G, are approved for 1st-line treatment (tx) of advanced EGFRm+ NSCLC. In LL7, A (40 mg/d) significantly improved PFS (HR 0.73 [95% CI 0.57–0.95], p = 0.017), ORR (70 vs 56%, p = 0.008) and time to tx failure (TTF; HR 0.73 [0.58–0.92], p = 0.007) vs G (250 mg/d) in this setting. Here, we present primary analysis of mature OS data.


LL7 assessed A vs G in tx-naïve pts with stage IIIb/IV NSCLC and a Del19/L858R EGFR mutation. Co-primary endpoints were PFS, TTF and OS. Other endpoints included ORR and AEs. Primary OS analysis was planned after ∼213 OS events and follow-up of ≥32 mos.


Events for OS analysis were met at the data cut-off of 8 Apr 2016. Median follow-up for OS: 42.6 mos. Median tx duration: 13.7 (A) vs 11.5 (G) mos. 73/77% (A/G) of pts had ≥1 subsequent systemic anti-cancer treatment after discontinuation of A/G. 46/56% (A/G) received a subsequent EGFR TKI; 20 (14%)/23 (15%) pts (A/G) received a 3rd-gen EGFR TKI. There was a trend towards improved OS with A vs G (median 27.9 vs 24.5 mos; HR 0.86 [0.66–1.12], p = 0.258). Landmark 24-mo and 30-mo OS rates were 61 vs 51% (A vs G) and 48 vs 40% (A vs G); these survival rates with A were similar to the LL3 trial (60 and 50% in pts with common EGFR mutations). Prespecified subgroup analyses showed similar OS trends with A vs G in pts with Del19 (30.7 vs 26.4 mos; HR 0.83 [0.58–1.17]) and L858R (25.0 vs 21.2 mos; HR 0.92 [0.62–1.36]) mutations. There was a trend towards improved OS with A vs G in pts who received a 3rd-gen EGFR TKI (NE vs 46.0 mos; HR 0.51 [0.17–1.52]). In pts treated with A, consistent OS outcomes were observed across age groups (median, mos: 27.9 [≥60 yrs]; 26.7 [≥65 yrs]; 25.1 [≥70 yrs]; 27.9 [≥75 yrs]). Updated PFS, TTF and ORR data were similar to the primary analyses; all were significantly improved with A vs G. The AE profile of A and G was virtually unchanged since the primary analysis.


In LL7, there was no significant difference in OS with A vs G. A trend favouring afatinib, generally consistent across subgroups, was observed. Updated analyses of PFS (independent), TTF and ORR all significantly favoured A over G.
