What is an angiogenesis inhibitor?
An angiogenesis inhibitor is a naturally occurring or synthetic molecule that can interfere with or “block” angiogenesis. Since abnormal angiogenesis rarely turns itself off spontaneously, the goal of antiangiogenic therapy is to stop the formation of new blood vessels and to break up the existing abnormal blood vessels. Angiogenesis inhibitors target new, growing blood vessels and do not affect normal resting blood vessels in the body.
