Safety assessment of drotrecogin alfa (activated) in the treatment of adult patients with severe sepsis

Introduction Drotrecogin alfa (activated; recombinant activated protein C) was shown to reduce 28-day all-cause mortality in patients with severe sepsis and to have an acceptable safety profile in 1690 patients studied in the F1K-MC-EVAD (PROWESS) trial. We analyzed all available data on the safety of treatment with drotrecogin alfa (activated) in 2786 adult patients with severe sepsis enrolled in all phase 2 and 3 clinical trials, and in an estimated 3991 patients receiving the drug in commercial use.
