OR
b. Minor Criteria: two of the following criteria documented within the previous 24
hours in subjects without evidence of rapid clinical improvement:
i. Systolic blood pressure < 90 mm Hg or MAP < 70 mm Hg and received >= 40 mL/kg of fluid resuscitation over a 6 hour period or vasopressors at therapeutic doses (see above) for at least 2 hours to maintain a SBP >= 90 mm Hg or a MAP >= 70 mm Hg;
ii. PaO2/FiO2 ratio < 250 or a respiratory rate >= 30/min or the need for noninvasive mechanical ventilatory support;
iii. Blood urea nitrogen (BUN) > 7.0 mM (> 19.6 mg/dL);
iv. New onset mental confusion (must be documented prior to the use of sedative or other new psychotropic medication);
v. Multi-lobar pneumonia;
vi. Platelet count < 100,000 cells/mm3 or a fall of > 25% during the previous 48 hours to a count of < 120,000 cells/mm3;
vii. Leukopenia (WBC <= 4 x 10*9/L);
viii. Hypothermia (core temperature <= 36°C).
4. Ability to initiate treatment as soon as all entry criteria have been met, and no later than 36 hours of ICU admission and within 72 hours of hospitalization (time of
hospitalization is the time of initial presentation to the emergency department,
hospital ward admission or admission to a transferring medical facility, whichever is
earliest).
5. Informed consent.
The investigator has ruled out to the best of his ability any infectious or non-infectious
condition that may mimic severe CAP (e.g., Congestive Heart Failure [CHF], Pulmonary
Embolism [PE]).

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After a potential patient has been identified and appears to meet all study entry criteria, the investigator will contact the study Clinical Coordination Center. All pertinent subject information will be reviewed and, if the subject is determined to satisfy all entry criteria, the CCC will approve the accrual of the subject. This site will then access the Interactive Voice Response System (IVRS) for subject randomisation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Subjects will be randomly assigned to receive tifacogin 0.025 mg/kg/h, 0.075 mg/kg/h or placebo in an equal allocation ratio. The method of sequence generation is simple randomisation by using a randomisation table created by a computer software (i.e., computerised sequence generation).
