A Study in Preterm Neonates With Respiratory Distress Syndrome (RDS) Comparing CUROSURF® Administration Through Less Invasive Surfactant Administration (LISA) and Conventional Administration

This study compared the administration of porcine surfactant (poractant alfa, Curosurf®) through a less invasive method (LISA), using a thin catheter, CHF 6440 (LISACATH®), during non-invasive ventilation (CPAP, NIPPV, BiPAP) with an approved conventional surfactant administration during invasive ventilation followed by rapid extubation in terms of short term and mid-term safety and efficacy in spontaneously breathing preterm neonates who have clinical signs of respiratory distress syndrome (RDS).
