Abstract
Background and Objectives
Ramucirumab is a fully immunoglobulin
G (lgG) monoclonal antibody targeting vascular endothelial growth factor receptor type 2 (VEGFR2). Previous clinical trials suggested ramucirumab could improve the survival and increase the risk of adverse effects. Here, we aimed to assess the efficacy and safety of ramucirumab in the treatment of advanced solid tumors.
Methods
Publications were searched from Pubmed, Embase database and clinicaltrials.gov. Hazard ratio (HR) and 95 % confidence interval (95 % CI) were calculated to evaluate efficacy, and the risk ratio (RR) for adverse effects.
Results
Ten relevant studies were included. Ramucirumab resulted in significant benefit in overall survival [OS, HR and 95 % CI 0.87 (0.82–0.93), I
2: 0.0 %] and progression-free survival [PFS, HR and 95 % CI 0.74 (0.66–0.82), I
2: 67.4 %]. Also the difference of time to progression (TTP) and objective response rate (ORR) between two groups were also significant [0.70 (0.57–0.88) and 1.78 (1.40–2.25), respectively]. Ramucirumab could increase the risk of total adverse effects (TAEs, of any grade) by 1 % (from 0 to 2 %) and severe adverse effects (SAEs, grade > 2) by 17 % (from 9 to 26 %). The most frequently occurring TAEs were fatigue (54.71 %), neutropenia (42.74 %), bleeding (37.55 %), nausea (34.63 %) and stomatitis (33.74 %). Most frequently occurring SAEs (grade ≥3) were neutropenia (33.43 %), fatigue (12.08 %), leukopenia (10.59 %), hypertension (8.99 %) and liver injury (8.74 %).
Conclusion
Ramucirumab could improve OS and PFS for patients suffering from advanced solid tumors. Ramucirumab could increase the risk of TAEs and SAEs.
