AbstractContinued safety assessment is essential for any newly approved therapy. Drotrecogin alfa (activated; DrotAA), which is approved for use in severe sepsis, has undergone clinical trials with corresponding safety analyses since 1995. However, the only comprehensive review of all trials is that reported in 2003 by Bernard and coworkers. This is an important review that focuses on the safety profile of DrotAA in all published studies (six randomized clinical trials and five national registry studies) and in previously unpublished data. DrotAA treatment is associated with an increased risk for bleeding (which in general is manageable). Nevertheless, the available evidence shows that any adverse effects of DrotAA are outweighed by its benefits in patients with severe sepsis who are at high risk for death. So far, more than 9,000 patients have been enrolled in clinical trials involving DrotAA, providing a valuable safety database. It is of note that although DrotAA does increase the risk of bleeding, this has not been associated with an overall increase in the rate of all severe adverse events.
