what is Avastin?

Avastin (or Bevacizumab) is similar to Lucentis. Avastin is actually the larger "parent molecule" from which Avastin is derived.
Avastin is a drug that was actually developed for metastatic colon cancer...but has effects similar to Lucentis. It has however not been studied as extensively in eye disease. A study is currently underway...comparing Avastin and Lucentis. Results are anticipated in approximately 2011.
