  • Title: Anti-lipoteichoic acid monoclonal antibody (pagibaximab) studies for the prevention of staphylococcal bloodstream infections in preterm infants.

    Journal: Expert Opin Biol Ther; 2015 Apr; 15(4):595-600. PubMed ID: 25736524.
    Abstract:
    INTRODUCTION: Advances in modern medicine have given very low birth weight (VLBW) infants a better chance of survival; however, these infants remain at high risk for developing nosocomial infections associated with increased morbidity and mortality. The ability of antistaphylococcal immunoglobulins, Altastaph and INH A-2, to augment the neonatal immune system to prevent infections has been studied and evaluated in a 2009 Cochrane review. AREAS COVERED: Our objective is to evaluate the safety and efficacy of a third antistaphylococcal immunoglobulin, pagibaximab, in the prevention of staphylococcal infection in preterm infants. Three studies of pagibaximab, Phases I, II and III, were examined in terms of study design, pharmacokinetics, development of sepsis and adverse effects. EXPERT OPINION: These studies demonstrated safety and tolerability of pagibaximab with no observed reduction in sepsis. Reported adverse events in both treatment and placebo groups were similar and consistent with events commonly observed in VLBW infants. Antistaphylococcal immunoglobulins alone have been unsuccessful in preventing nosocomial infections. Further investigations need to evaluate any potential immunomodulating products in preterm animal models prior to human studies. Future studies are required to determine how to best augment the immature immune system, likely through the use of multiple immunomodulating agents to successfully prevent infections in preterm infants.
