Ramucirumab is a human IgG1 (Immunoglobulin G) monoclonal antibody that targets the extracellular domain of VEGFR-2 (vascular endothelial growth factor receptor). A recent double-blind, placebo-controlled clinical trial evaluated the addition of ramucirumab to docetaxel compared with docetaxel and placebo in patients with Stage IV squamous and non-squamous NSCLC in the 2nd-line treatment setting. This study demonstrated a superior overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) with the combination therapy compared with docetaxel with placebo. This effect was seen across histologic subtypes, in the absence of excess toxicity in patients with squamous cell histology. This finding is intriguing, as prior study of bevacizumab in patients with NSCLC of squamous cell histology was associated with excess pulmonary hemorrhage. This provides the rationale for further investigation of ramucirumab in patients with squamous cell NSCLC.
