Benefit/risk profile of drotrecogin alfa (activated) in surgical patients with severe sepsis

Abstract

Background: The Protein C Worldwide Evaluation in Severe Sepsis (PROWESS) trial examined the safety and efficacy of drotrecogin alfa (activated) (Xigris) in adult patients with severe sepsis. A clinical evaluation committee examined clinical data for each patient enrolled in PROWESS. However, there were no surgeons on the committee, and thus questions remained regarding the safety and efficacy of drotrecogin alfa (activated) in surgical patients.

Methods: Masked to treatment, a Surgical Evaluation Committee adjudicated the presence and type of operation, timing of surgery, infection, and adequacy of source control of surgical patients included in PROWESS.

Results: Twenty-eight percent of PROWESS cases were confirmed as surgical. The absolute risk reduction for mortality in all surgical patients was 3.2% and 9.1% for patients undergoing intraabdominal procedures. Serious bleeding during the infusion and 28-day period was similar between surgical and nonsurgical patients.

Conclusions: Consistent with the overall PROWESS results, drotrecogin alfa (activated) has a favorable benefit/risk profile in surgical patients.
