    Clinical Question


    Does drotrecogin alfa (activated) (DrotAA) reduce mortality in adults with septic shock?

    Bottom Line


    Drotrecogin alfa (activated) did not significantly reduce mortality at 28 or 90 days compared to placebo in adults with septic shock.

    Major Points




    Guidelines


    Drotrecogin alfa (activated) was approved for use in severe sepsis patients with a high risk of death. However, post-approval studies failed to demonstrate benefits for less severely ill adults and children, leading to further scrutiny and the need for this study.

    Design


    Multicenter, double-blind, placebo-controlled, randomized trial.

    Population


    Included 1697 adult patients with infection, systemic inflammation, and shock, receiving a threshold dose of fluids and vasopressors for at least 4 hours.

    Interventions


    Patients randomly assigned to receive DrotAA (24 μg per kg per hour) or placebo for 96 hours.

    Outcomes


    The primary outcome was death from any cause at 28 days after randomization.

    Major Points


    At 28 days, mortality was 26.4% in DrotAA group vs. 24.2% in the placebo group (relative risk 1.09; 95% CI, 0.92 to 1.28; P=0.31). Mortality at 90 days was 34.1% for DrotAA vs. 32.7% for placebo (relative risk 1.04; 95% CI, 0.90 to 1.19; P=0.56).

    Criticisms


    The study was limited by the lack of in-depth analysis of coagulation or inflammatory responses to the study drugs, which was available from previous trials. Mortality in the placebo group was lower than expected but similar to other contemporary studies.

    Funding


    The study was funded by Eli Lilly.
