In early February 2006, Genentech Inc. issued a joint press release with Roche Holding Corporation explaining that their phase III early-stage colon cancer trial of Avastin (bevacizumab, Genentech Inc., South San Francisco, CA) would be stopped after the deaths of four patients. This announcement was the result of preliminary review of the data by the Data Safety Monitoring Board (DSMB) that was formed to monitor the study. What is the DSMB? What criteria does it use to determine whether a study should be stopped early? The purpose of this article is to (a) explain the role of the DSMB, (b) give an overview of the Avastin Adjuvant (AVANT) study, and (c) provide information and resources about clinical trials for practicing RNs in oncology.
