Clinical Question:
Is drotrecogin effective in treating septic children?

Bottom Line:
Drotrecogin (Xigris) is no more effective than placebo in improving outcomes in septic children.

Study Design:
Randomized controlled trial (double-blinded)

Drotrecogin alfa (activated) (DrotAA) is used for the treatment of adults with severe sepsis who have a high risk of dying. A phase 1b open-label study has indicated that the pharmacokinetics and pharmacodynamics of DrotAA are similar in children and adults. The authors initiated the RESOLVE (REsearching severe Sepsis and Organ dysfunction in children: a gLobal perspectiVE) trial to investigate the efficacy and safety of the drug in children. They recruited children aged between 38 weeks’ corrected gestational age and 17 years with sepsis-induced cardiovascular and respiratory failure were randomly assigned to receive placebo or DrotAA (24 microg/kg/h) for 96 h. We used a prospectively defined, novel primary endpoint of Composite Time to Complete Organ Failure Resolution (CTCOFR) score. Secondary endpoints were 28-day mortality, major amputations, and safety. Analysis was by intention-to-treat. This trial is registered with, number NCT00049764. As to their finfings, 477 patients were enrolled; 237 received placebo, and 240 DrotAA. Results showed no significant difference between groups in CTCOFR score (p=0.72) or in 28-day mortality (placebo 17.5%; DrotAA, 17.2%; p=0.93). Although there was no difference in overall serious bleeding events during the 28-day study period (placebo 6.8%; DrotAA 6.7%; p=0.97), there were numerically more instances of CNS bleeding in the DrotAA group (11 [4.6%], vs 5 [2.1%] in placebo, p=0.13), particularly in children younger than 60 days. For CTCOFR score days 1-14, correlation coefficient was -0.016 (95% CI -0.106 to 0.74); relative risk for 28-day mortality was 1.06 (95% CI 0.66 to 1.46) for DrotAA compared with placebo.
