Randomized Controlled Trial Multicenter Study Clinical Trial
Bactericidal/permeability-increasing protein (rBPI21) in patients with hemorrhage due to trauma: results of a multicenter phase II clinical trial. rBPI21 Acute Hemorrhagic Trauma Study Group.
Infection and organ failure are the most common causes of death or serious complication in trauma patients surviving initial resuscitation and operation. Of the many possible causes of these complications, bacterial translocation and release of harmful cytokines and oxygen free radicals may play an important role in the pathogenesis of the complications associated with traumatic hemorrhage. Recombinant human bactericidal/permeability-increasing protein (rBPI21) has antibacterial and antiendotoxin properties, reduces cytokine levels, and increases survival in animal models of hemorrhagic shock. The primary objective of this study was to evaluate the safety and efficacy of prophylactic rBPI21 infusion in patients with hemorrhage due to trauma. ⋯ rBPI21 was well-tolerated and demonstrated a favorable trend in reducing the composite primary end point of mortality or serious complication through day 15, especially respiratory complications, in patients with hemorrhage due to trauma. A phase III study is currently in progress.
