Study information

Primary study designInterventional
Study designRandomised controlled trial
Secondary study designRandomised controlled trial
Scientific title
Study objectivesTo determine if high-dose antithrombin III (administered within 6 hours of onset) would provide a survival advantage in patients with severe sepsis and septic shock.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedSepsis
InterventionPatients were randomly assigned to receive 30 000 IU antithrombin III (Aventis Behring, Marburg, Germany) with a loading dose of 6000 IU (given over 30 minutes), followed by a continuous IV infusion of 6000 IU per day for 4 days, or an equivalent volume of placebo solution (1% of human albumin).
Intervention typeDrug
PhaseNot Specified
Drug / device / biological / vaccine name(s)Antithrombin III
Primary outcome measure(s)

28-day all-cause mortality in the primary efficacy population.

Key secondary outcome measure(s)

1. Survival time within 7 days
2. Length of intensive care unit stay within 7 days
3. Occurrence of new organ dysfunction (according to Logistic Organ Dysfunction score) within 7 days
4. Severity of sepsis was assessed via the Simplified Acute Physiology Score version II(SAPS II)
5. Surgical interventions and bleeding events, recorded for 28 days
6. Other serious adverse events, recorded for 14 days
7. Antithrombin III plasma concentrations (functional) at baseline and after 24 hours
8. Activated partial thromboplastin time and prothrombin time values, assessed at baseline and 3 times daily for days 1 through 5 and on day 7

Completion date01/01/2000
