Background Angiogenesis is an important therapeutic target in colorectal carcinoma. Ramucirumab is a human IgG-1 monoclonal antibody that targets the extracellular domain of VEGF receptor 2.

We assessed the efficacy and safety of ramucirumab versus placebo in combination with second-line FOLFIRI (leucovorin, fluorouracil, and irinotecan) for metastatic colorectal cancer in patients with disease progression during or after first-line therapy with bevacizumab, oxaliplatin, and a fluoropyrimidine. Methods Between Dec 14, 2010, and Aug 23, 2013, we enrolled patients into the multicentre, randomised, double-blind, phase 3 RAISE trial.

Eligible patients had disease progression during or within 6 months of the last dose of first-line therapy. Patients were randomised (1: 1) via a centralised, interactive voice-response system to receive 8 mg/kg intravenous ramucirumab plus FOLFIRI or matching placebo plus FOLFIRI every 2 weeks until disease progression, unacceptable toxic effects, or death.

Randomisation was stratified by region, KRAS mutation status, and time to disease progression after starting first-line treatment. The primary endpoint was overall survival in the intention-to-treat population.

This study is registered with ClinicalTrials.gov, number NCT01183780.ld Findings We enrolled 1072 patients (536 in each group). Median overall survival was 13.3 months (95% CI 12.4-14.5) for patients in the ramucirumab group versus 11.7 months (10.8-12.7) for the placebo group (hazard ratio 0.844 95% CI 0.730-0.976; log-rank p=0.0219).

Survival benefit was consistent across subgroups of patients who received ramucirumab plus FOLFIRI. Grade 3 or worse adverse events seen in more than 5% of patients were neutropenia (203 [38%] of 529 patients in the ramucirumab group vs 123 [23%] of 528 in the placebo group, with febrile neutropenia incidence of 18 [3%] vs 13 [2%]), hypertension (59 [11%] vs 15 [3%]), diarrhoea (57 [11%] vs 51 [10%]), and fatigue (61 [12%] vs 41 [8%]).
