Drotrecogin alfa (activated), a recombinantly produced preparation of human
activated protein C, reduces the inflammatory, procoagulant, and antifibri
nolytic host response to infection. At press time, an FDA advisory committe
e was split over whether to recommend it for approval for treating severe s
epsis. An FDA decision on approval was expected at the end of October. The
large PROWESS trial demonstrated a 6.1% absolute reduction In the risk of d
eath in adults with severe sepsis treated with drotrecogin alfa as opposed
to placebo (p = 0.005). At the same time, there was a trend toward an incre
ased incidence of serious bleeding with drotrecogin alfa compared with plac
ebo. Clinical efficacy has not been demonstrated in pediatric patients with
sepsis and must at this point be extrapolated from the PROWESS trial. The
cost of the drotrecogin alfa is unknown at press time but is expected to be
considerable. Pharmacoeconomic analysis is needed to further define the ag
ent's role in patients with severe sepsis, Treatment benefit is not proven
in patients who do not meet predefined inclusion criteria; therefore, poten
tial candidates for drotrecogin alfa therapy should be carefully screened a
nd stringent institutional protocols developed for optimal use.
