Secondary Outcome Measures:
  • Worst Murray Lung Injury Score
  • Worst Multiple Organ Dysfunction (MOD) Score (Marshall) (measured at Days 1 through 7, and Day 28)
  • Infections-nosocomial and/or surgical site infections
  • Ventilator-free days
  • Mortality (measured at Day 28)

Study Completion Date: June 2007
Detailed Description:


This study will use IC14, a recombinant chimeric monoclonal antibody (mAb) recognizing CD14, to block CD14 medicated cellular activation in patients with sepsis-induced ALI. Research results of antibody interaction with CD14 suggest that CD14 has a central role in the recognition of bacterial products and the induction of innate immune responses. Although beneficial, when this response is combined with a component of alveolar stretch it may induce an exaggerated response that can be harmful. This study will implement strategies to block CD14-mediated cellular activation and will evaluate whether this strategy has a beneficial effect in reducing alveolar inflammatory response, mechanical ventilation days, multiple organ failure, and severity of organ dysfunction in patients with sepsis-induced ALI.


The primary outcome of this study will be alveolar lavage concentrations of interleukin-8 that will be measured post-treatment at Days 2 and 3, and Days 6 to 8.

The key secondary outcomes of this study will be: 1) Worst Murray Lung Injury Score (measured at Days 1 through 7, and Day 28); 2) Worst Multiple Organ Dysfunction (MOD) Score (Marshall) (measured at Days 1 through 7, and Day 28); 3) Infections-nosocomial and/or surgical site infections (measured at Day 28); 4) Ventilator-free days (measured at Day 28); and 5) Mortality (measured at Day 28).


Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)

Inclusion Criteria:

  • Presence of ALI, defined as the following:

    1. Acute onset (less than 28 days from study entry)
    2. PaO2/FiO2 of less than 300
    3. Bilateral infiltrates consistent with pulmonary edema on frontal chest radiograph (infiltrates may be patchy, diffuse, homogeneous, or asymmetric)
    4. Requirement for positive pressure ventilation via endotracheal tube
    5. No clinical evidence of left atrial hypertension
  • Clinical indication for antimicrobial therapy at the time of randomization

Exclusion Criteria:

  • Treatment with a drug or device within 30 days prior to study entry that has not received regulatory approval at the time of study entry
  • Does not meet safety criteria for bronchoscopic alveolar lavage either at baseline or is anticipated to be too high a risk for lavage on Day 1 of the study
  • Intubation for cardiopulmonary arrest
  • Intubation for status asthmaticus, pulmonary embolus, or myocardia infarction
  • Anticipated survival less than 48 hours from intubation
  • Anticipated survival less than 28 days due to pre-existing medical condition
