VEGF Trap, also known as Aflibercept, is a fusion protein designed to inhibit Vascular Endothelial Growth Factor (VEGF). VEGF is crucial for the process of angiogenesis, which is the formation of new blood vessels. Angiogenesis is essential for tumor growth and metastasis, supplying the tumor with nutrients and oxygen. By blocking VEGF, VEGF Trap aims to "starve" the tumor by preventing the formation of new blood vessels.
