Ramucirumab plus docetaxel versus placebo plus docetaxel for second-line treatment of stage IV non-small-cell lung cancer after disease progression on platinum-based therapy (REVEL): a multicentre, double-blind, randomised phase 3 trial

WOS: 000341359100024PubMed ID: 24933332Background Ramucirumab is a human IgG1 monoclonal antibody that targets the extracellular domain of VEGFR-2. We aimed to assess efficacy and safety of treatment with docetaxel plus ramucirumab or placebo as second-line treatment for patients with stage IV non-small-cell-lung cancer (NSCLC) after platinum-based therapy. Methods In this multicentre, double-blind, randomised phase 3 trial (REVEL), we enrolled patients with squamous or non-squamous NSCLC who had progressed during or after a first-line platinum-based chemotherapy regimen. Patients were randomly allocated (1:1) with a centralised, interactive voice-response system (stratified by sex, region, performance status, and previous maintenance therapy [yes vs no]) to receive docetaxel 75 mg/m(2) and either ramucirumab (10 mg/kg) or placebo on day 1 of a 21 day cycle until disease progression, unacceptable toxicity, withdrawal, or death. The primary endpoint was overall survival in all patients allocated to treatment. We assessed adverse events according to treatment received. This study is registered with ClinicalTrials.gov, number NCT01168973. Findings Between Dec 3, 2010, and Jan 24, 2013, we screened 1825 patients, of whom 1253 patients were randomly allocated to treatment. Median overall survival was 10.5 months (IQR 5.1-21.2) for 628 patients allocated ramucirumab plus docetaxel and 9.1 months (4.2-18.0) for 625 patients who received placebo plus docetaxel (hazard ratio 0.86, 95% CI 0.75-0.98; p=0.023). Median progression-free survival was 4.5 months (IQR 2.3-8.3) for the ramucirumab group compared with 3.0 months (1.4-6.9) for the control group (0.76, 0.68-0.86; p
