Abstract 1404


The combination of pemetrexed (P)-based chemotherapy with EGFR-tyrosine kinase inhibitors (TKI) has resulted in improved efficacy vs EGFR-TKI alone for treatment (tx) of advanced NSCLC with EGFR-mut. The objective of this disclosure is to report OS, updated progression-free survival (PFS), and safety of P+Gefitinib (G) vs G alone in patients (pts) with advanced NS NSCLC with EGFR-mut.


Primary outcome of this phase II, multicenter, randomized study has been published. Pts were randomly assigned to receive P+G or G alone at a ratio of 2:1 (P, 500 mg/m2 on day (d) 1 of every 21-d cycle; G, 250 mg/d). Primary and secondary objectives were PFS and OS, respectively. Adjusted Cox regression model was used to estimate adjusted HR for difference between tx arms.


191 pts were randomized to P+G (n = 126) or G (n = 65). Majority of the pts were female (P+G [65%], G [63%]), non-smokers (P+G [64%], G [72%]), and had stage IV disease (P+G [83%], G [88%]). At final database lock, 111 (58.1%) pts had OS events (death; P+G [n = 72], G [n = 39]) while 164 pts had PFS events (progression or death; P+G [n = 102], G [n = 62]). OS was numerically higher in pts receiving P+G (43.4 months; 95% CI, 33.4-50.8) vs G alone (36.8 months; 95% CI, 26.7-42.6); adjusted HR, 0.77; 95% CI, 0.5-1.2; one-sided P = 0.105. In this updated analysis, PFS continued to be prolonged in P+G group (16.2 months; 95% CI, 12.6-18.7) vs G alone (11.07 months; 95% CI, 9.7-13.8); adjusted HR, 0.67; 95% CI, 0.5-0.9; one-sided P = 0.009. A higher % of pts in G arm received post-discontinuation systemic tx, (P+G, 68.3%; G, 78.5%), including 37 (56.9%) pts who received P. The most common drug related all grade adverse events (AEs) reported for P+G vs G were rash (53.2% vs 55.4%), diarrhea (45.2% vs 47.7%), and pruritus (35.7% vs 32.3%). Thirteen pts reported serious AEs (SAEs; P+G [n = 12, G [n = 1]); 1 pt in each arm discontinued due to SAEs. Two deaths were reported in P+G arm due to AEs.


Combination of P+G demonstrated numerically higher OS compared with G alone in tx-naïve pts with EGFR-mut advanced NS NSCLC. PFS was significantly prolonged with P+G and more pts experienced AEs in P+G vs G arm.
