Comparison of the efficacy, safety, and therapeutic usage of HA-1A and E5 in the treatment of gram-negative sepsis.
Clinical trials have shown that the murine monoclonal antibody E5 and the human hybrid monoclonal antibody HA-1A increase survival of patients with gram-negative sepsis. However, significant reduction in mortality associated with E5's use was limited to patients who had not progressed to refractory shock. Patients treated with E5 compared to placebo receivers were also significantly more likely to experience resolution of organ failures. Significant reductions in morbidity and mortality associated with HA-1A's use were limited to patients with gram-negative bacteremia, and occurred even in patients with shock. Treatment with HA-1A also had a significant positive effect on resolution of the major complications of sepsis (shock, disseminated intravascular coagulation, acute renal failure, acute hepatic failure, or adult respiratory distress syndrome) in patients with documented gram-negative bacteremia. Both products appear to be safe, with generally mild, transient, and clinically insignificant adverse effects reported.
