Xigris�. A new WARNING has been added to the prescribing information for Xigris [drotrecogin alfa(activated)], a biological therapeutic product indicated for the treatment of adult patients with severe sepsis who are at high risk of death.

The warning is based upon exploratory analyses of the ADDRESS clinical trial database and subsequent reanalysis of the PROWESS (Phase 3 registration) clinical trial
database. This new warning, applies only to patients with single organ dysfunction and recent surgery. These patients may not be at high risk of death and therefore may not be indicated for drotrecogin alfa.

mortality was numerically higher in the drotrecogin alfa group (28-day: 10/49; in-hospital:14/48) compared to the placebo group (28-day: 8/49; in-hospital: 8/47).
