- Abstract
- An age subgroup analysis was conducted on patients with non-small-cell lung cancer from the REVEL trial (younger than 65 years: n = 798; 65 years or older: n = 455). Ramucirumab in combination with docetaxel showed no significant additional risks to older patients. This second-line study suggests ramucirumab treatment was more pronounced in patients younger than 65 years. Introduction: Ramucirumab, a recombinant human immunoglobulin G1 monoclonal antibody receptor antagonist designed to block the ligand-binding site of vascular endothelial growth factor receptor-2 (VEGFR-2), was evaluated as second-line treatment in combination with docetaxel in patients with non-small-cell lung cancer in the REVEL trial (NCT01168973). Ramucirumab significantly improved overall survival (OS) and progression-free survival (PFS). We report age subgroup analysis results primarily on the basis of a 65-year cutoff. Patients and Methods: Patients were randomized 1: 1 to ramucirumab with docetaxel or placebo with docetaxel (n = 1253). Of these, 798 were younger than 65 years (ramucirumab, n = 391; control, n = 407) and 455 were 65 years or older (ramucirumab, n = 237; control, n = 218). Treatment comprised 21-day cycles of 75 mg/m(2) docetaxel with 10 mg/kg ramucirumab or placebo. Prespecified age subgroup analyses were performed, including OS, PFS, and objective response rate. Quintiles age analysis was conducted to establish a relationship between efficacy and age. The Lung Cancer Symptom Scale (LCSS) measured quality of life outcomes. Safety was assessed according to adverse events (AEs). Results: Patients younger than 65 years showed favorable OS outcomes with ramucirumab treatment (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.62-0.87; P < .001) and PFS (HR, 0.68; 95% CI, 0.59-0.79; P < .001). In patients 65 years or older, benefits of ramucirumab were not as evident; after model adjustment for prognostic factors, OS and PFS HRs were 0.96 (95% CI, 0.77- 1.21; P = .04) and 0.87 (95% CI, 0.71-1.05; P = .03), respectively. Age analysis according to quintiles showed HRs favoring ramucirumab for all age groupings. LCSS scores and AEs did not considerably differ between age groups. Conclusion: In this subgroup analysis, true treatment effect differences on the basis of age have not been established, and treatment should not be deterred solely because of age.
