简要总结
This is a multicentre, phase III, 2-arm, masked randomized controlled trial. The primary hypothesis is that oral bovine lactoferrin (bLF), through its antimicrobial, antioxidant and anti-inflammatory properties, will reduce the rate of mortality or major morbidity in very low birth weight (VLBW) preterm infants.
详细描述
Almost 3,000 very low birth weight (VLBW), <1500g preterm infants are born and treated in Canada annually. About 1,200 either die or survive with severe brain or lung injury, retinopathy, late-onset sepsis or necrotizing enterocolitis (NEC), each of which is associated with substantial risk of childhood disability.
Lactoferrin is an antimicrobial, antioxidant, anti-inflammatory iron-carrying, bifidogenic glycoprotein found in all vertebrates and in mammalian milk, leukocytes and exocrine secretions. However, most VLBW infants receive insufficient human lactoferrin (hLF) from human breast milk in the first months of life, resulting in suboptimal protection. Because hLF is expensive, bovine lactoferrin (bLF) has been considered as an alternate supplement to improve this suboptimal protection.
LIFT is one of several ongoing trials using higher doses of bovine bLF in the VLBW population (120-200 mg/kg/d). If LIFT confirms a 19% reduction in the relative risk of its primary outcome, bLF will have a major impact, translating into thousands more intact survivors without major morbidity in Australia, New Zealand, Canada, Europe and worldwide each year. As >90% of very preterm survivors at hospital discharge reach adulthood, this represents more than 19,000 life-years gained in Canada alone each year, one of the largest gains in intact survival in any specialty since neonatal surfactant and antenatal steroids

- Weight and head circumference at 36 weeks corrected gestation(Randomization to 36 weeks corrected gestation or to transfer/discharge if earlier)
- Time to first day of full enteral feeds (≥120ml/kg/day for 3 consecutive days)(Randomization to 36 weeks corrected gestation or to transfer/discharge if earlier)
- Number of blood transfusions(Randomization to 36 weeks corrected gestation or to transfer/discharge if earlier)
- Incidence of each of the 5 components of the composite primary endpoint(Randomization to 36 weeks corrected gestation or to transfer/discharge if earlier)
- Length of hospital stay(Randomization to 36 weeks corrected gestation or to transfer/discharge if earlier)
- Incidence of death by 24 months corrected age or the presence of neurodevelopmental outcomes at 24 months corrected age(Randomization to 36 weeks corrected gestation)
- Incidence of all-cause in-hospital mortality(Randomization to 36 weeks corrected gestation or to transfer/discharge if earlier)
