In the version of the article originally published, it was stated that “Avastin was studied in combination with Taxol in all these trials, and compared to Taxol alone.” It should have read, “Avastin was studied in combination with chemotherapy.” In addition, it stated that the FDA had rescinded approval of Avastin for metastatic breast cancer. It should have read, the FDA “recommended removal of the breast cancer indication from the Avastin label...” The errors have been corrected in the HTML and PDF versions of the article.
