Lay summary Not provided at time of registration
Ethics approval Not provided at time of registration
Study design Randomised controlled trial
Countries of recruitment Czech Republic, Denmark, Germany, South Africa, United Kingdom, United States of America
Disease/condition/study domain Sepsis
Participants - inclusion criteria 1. Adult hospitalised men and women (greater than or equal to 18 years)
2. Gave informed consent
3. Met the following criteria within a 6-hour period:
3.1. Clinical evidence of sepsis with a suspected source of infection
3.2. Body temperature (rectal or core) higher than 38.5°C or lower than 35.5°C
3.3. Leukocyte count higher than 10 x 10^3/µL or lower than 3.5 x 10^3/µL
4. Three of the following 6 signs had to be met within the same 6-hour period:
4.1. Tachycardia (heart rate greater than 100/min)
4.2. Tachypnoea (greater than 24/min) or mechanical ventilation because of septic indication
4.3. Hypotension with systolic blood pressure lower than 90 mm Hg despite sufficient fluid replacement or the need of vasoactive agents to maintain systolic blood pressure of 90 mm Hg or greater
4.4. Thrombocytopenia with platelet counts of less than 100 x 103/µL
4.5. Elevated lactate levels (above upper limit of normal range) or metabolic acidosis (pH less than 7.3 or base excess -10 mmol/L) not secondary to respiratory alkalosis
4.6. Oliguria with urine output of less than 20 mL per hour despite sufficient fluid replacement

Anticipated end date 01/01/2000
Status of trial Completed
Patient information material
Target number of participants 2,314
Interventions Patients 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).
Primary outcome measure(s) 28-day all-cause mortality in the primary efficacy population.
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
