Abstract 1440

Background

Ramucirumab, a human IgG1 monoclonal antibody receptor antagonist of vascular endothelial growth factor receptor 2 (VEGFR-2), has been approved for treatment in gastric/gastroesophageal junction, non-small cell lung, and metastatic colorectal cancers. A total of 6 global, randomized, double-blind, placebo-controlled, phase 3 trials across multiple tumor types and a large patient population have currently been completed. To further establish the safety profiles of ramucirumab, a meta-analysis has been performed based on the data from these 6 trials and the results are presented here.

Methods

Fixed-effects or mixed-effects models were used to conduct an individual patient meta-analysis across the 6 completed phase 3 trials and derive the relative risk (RR) and associated 95% confidence intervals (CIs) for all-grade and high-grade (Grade ≥3) adverse events (AEs) possibly related to VEGF pathway inhibition.

Results

This meta-analysis included a total of 4996 treated patients (2748 patients in ramucirumab arms, 2248 in control arms). Proteinuria, gastrointestinal (GI) perforation, hypertension, wound-healing complications, infusion-related reactions, and low-grade (Grade 1-2) bleeding were observed at a higher percentage in the ramucirumab arms compared to control. However, our data did not demonstrate a definite increased risk with ramucirumab in high-grade bleeding (RR: 1.1, 95% CI 0.8-1.5), high-grade GI bleeding (RR: 1.1, 95% CI 0.7-1.7), venous thromboembolic events (VTE, all-grade, RR: 0.7, 95% CI 0.5-1.1; high-grade, RR: 0.7, 95% CI 0.4-1.2), or arterial thromboembolic events (ATE, all-grade, RR: 0.8, 95% CI 0.5-1.3; high-grade, RR: 0.9, 95% CI 0.5-1.7).

Conclusions

The risk of developing certain AEs with ramucirumab is consistent with other antiangiogenic agents; and, the safety profile is consistent with the ramucirumab labels. Our results showed no clear evidence for an increased risk of high-grade bleeding, high-grade GI bleeding, VTE, or ATE in this large and patient level meta-analysis.
