Guidance on patient Identification and Administration of Recombinant Human Activated protein C for the Treatment of Severe Sepsis

Abstract

Approximately one-third of cases of severe sepsis result in death. Endogenous activated protein C (ApC) plays a key role in the regulation of the inflammation, fibrinolysis and coagulation associated with severe sepsis. In a recently published phase III trial, protein C Worldwide Evaluation in Severe Sepsis (pROWESS), intravenous administration of recombinant human ApC (rhApC) 24 µg/kg/h for 96 h to patients with severe sepsis resulted in a 6.1% reduction in absolute mortality and a 19.4% reduction in the relative risk of death from any cause within 28 days (number needed to treat = 16). This dose is now being applied in clinical practice.
