Lucinactant: in neonatal respiratory distress syndrome.
Lucinactant, formerly known as KL(4) surfactant, is a novel synthetic lung surfactant containing phospholipids and an engineered peptide, sinapultide, which is designed to mimic the actions of human surfactant protein B. It has been developed for use in the prevention or treatment of respiratory distress syndrome (RDS), a common problem in premature infants, which results from a deficiency or degradation of pulmonary surfactant. Lucinactant is administered intratracheally soon after birth as a replacement surfactant. In the pivotal randomized, double-blind, prophylaxis trial in premature infants, the incidence of RDS at 24 hours after birth was significantly lower in lucinactant recipients than in recipients of colfosceril palmitate, a synthetic non-protein-containing surfactant. RDS-related mortality at 14 days was significantly lower in lucinactant recipients than in recipients of colfosceril palmitate or beractant, a bovine-derived surfactant. In another randomized, double-blind, prophylaxis trial in premature infants, the rate of survival without bronchopulmonary dysplasia at 28 days of age in lucinactant recipients was not inferior to that in recipients of poractant alfa, a porcine-derived surfactant. Lucinactant was generally well tolerated. Adverse events were transient and related to the administration procedure. There were no differences in the incidences of complications of prematurity between lucinactant and the other surfactants.

A multicenter, randomized, masked, comparison trial of lucinactant, colfosceril palmitate, and beractant for the prevention of respiratory distress syndrome among very preterm infants.
Evidence suggests that synthetic surfactants consisting solely of phospholipids can be improved through the addition of peptides, such as sinapultide, that mimic the action of human surfactant protein-B (SP-B). A synthetic surfactant containing a mimic of SP-B may also reduce the potential risks associated with the use of animal-derived products. Our objective was to compare the efficacy and safety of a novel synthetic surfactant containing a functional SP-B mimic (lucinactant; Discovery Laboratories, Doylestown, PA) with those of a non-protein-containing synthetic surfactant (colfosceril palmitate; GlaxoSmithKline, Brentford, United Kingdom) and a bovine-derived surfactant (beractant; Abbott Laboratories, Abbott Park, IL) in the prevention of neonatal respiratory distress syndrome (RDS) and RDS-related death.. We assigned randomly (double-masked) 1294 very preterm infants, weighing 600 to 1250 g and of < or =32 weeks gestational age, to receive colfosceril palmitate (n = 509), lucinactant (n = 527), or beractant (n = 258) within 20 to 30 minutes after birth. Primary outcome measures were the rates of RDS at 24 hours and the rates of death related to RDS during the first 14 days after birth. All-cause mortality rates, bronchopulmonary dysplasia (BPD) rates, and rates of other complications of prematurity were prespecified secondary outcomes. Primary outcomes, air leaks, and causes of death were assigned by an independent, masked, adjudication committee with prespecified definitions. The study was monitored by an independent data safety monitoring board.. Lucinactant reduced significantly the incidence of RDS at 24 hours, compared with colfosceril (39.1% vs 47.2%; odds ratio [OR]: 0.68; 95% confidence interval [CI]: 0.52-0.89). There was no significant difference in comparison with beractant (33.3%). However, lucinactant reduced significantly RDS-related mortality rates by 14 days of life, compared with both colfosceril (4.7% vs 9.4%; OR: 0.43; 95% CI: 0.25-0.73) and beractant (10.5%; OR: 0.35; 95% CI: 0.18-0.66). In addition, BPD at 36 weeks postmenstrual age was significantly less common with lucinactant than with colfosceril (40.2% vs 45.0%; OR: 0.75; 95% CI: 0.56-0.99), and the all-cause mortality rate at 36 weeks postmenstrual age was lower with lucinactant than with beractant (21% vs 26%; OR: 0.67; 95% CI: 0.45-1.00).. Lucinactant is a more effective surfactant preparation than colfosceril palmitate for the prevention of RDS. In addition, lucinactant reduces the incidence of BPD, compared with colfosceril palmitate, and decreases RDS-related mortality rates, compared with beractant. Therefore, we conclude that lucinactant, the first of a new class of surfactants containing a functional protein analog of SP-B, is an effective therapeutic option for preterm infants at risk for RDS.
