Gastric Cancer Management and Outcomes

Ramucirumab plus docetaxel prolongs survival in patients with non-small cell lung cancer (NSCLC) with disease progression after platinum-based therapy. This phase II, double-blind, randomized, placebo-controlled study assessed efficacy and safety of second-line ramucirumab-docetaxel in Japanese patients with NSCLC.Patients with NSCLC with progression after platinum-based therapy (28 Japanese sites; 19 December, 2012 to 22 May, 2015) were randomized (computer-generated sequence) to ramucirumab 10mg/kg or placebo, followed by docetaxel 60mg/m(2) (Day 1, 21-day cycle). Prior epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) monotherapy was prohibited in the primary population, but EGFR mutation-positive NSCLC patients who were treated with EGFR-TKI were enrolled as a separate exploratory population. Primary endpoint was progression-free survival (PFS); secondary outcomes included overall survival, tumor response rates, and safety. Investigator tumor assessments were used for the efficacy endpoints.In the primary population (N=160 randomized, n=157 treated), median (95% CI) PFS was longer with ramucirumab-docetaxel (5.22 [3.52-6.97] months; n=76) than with placebo-docetaxel (4.21 [2.83-5.62] months; n=81); hazard ratio 0.83 (95% CI 0.59-1.16). Median (95% CI) overall survival was 15.15 (12.45-26.55) months with ramucirumab-docetaxel and 14.65 (11.93-24.44) months with placebo-docetaxel (hazard ratio [95% CI] 0.86 [0.56-1.32]). Objective response rate (28.9% vs 18.5%) and disease control rate (78.9% vs 70.4%) were numerically greater with ramucirumab-docetaxel than with placebo-docetaxel. Incidence and severity of most adverse events were similar, but febrile neutropenia was more common with ramucirumab-docetaxel (34.2%) than with placebo-docetaxel (19.8%).Second-line ramucirumab-docetaxel improved PFS similar to that seen in the REVEL trial with a manageable safety profile in Japanese patients with NSCLC.
