Clinical Trial Summary

Nearly half of child deaths occur during the neonatal period, and 80% of those occur in babies with low birthweight. Although tremendous progress has been made towards reducing under-five mortality globally, declines in neonatal mortality lag behind those observed in older children. Low birthweight babies are at increased risk of poor outcomes compared to those who are term-appropriate for gestational age, including mortality, stunting, and growth failure. Recent evidence has demonstrated that the incidence of wasting and linear growth failure is highest between birth and 3 months of age, substantially earlier than previously thought. Interventions are urgently needed to improve outcomes in low birthweight babies; however, these interventions must not interfere with breastfeeding and thus some well-established interventions used to treat or prevent malnutrition in older children cannot be considered. The investigators recently demonstrated that biannual mass azithromycin distribution reduces all-cause childhood mortality by approximately 25% in infants aged 1-5 months, with stronger effects seen in underweight infants. This study did not include neonates due to the risk of infantile hypertrophic pyloric stenosis (IHPS) that has been hypothesized to be associated with macrolide use during early infancy. However, our study team documented only a single case of IHPS among 21,833 neonates enrolled in a trial of azithromycin versus placebo administered to neonates aged 8-27 days for prevention of infant mortality, documenting no major risk of IHPS associated with azithromycin. Here, the investigators propose an individually randomized trial where participants will receive a single oral dose of azithromycin (administered either during the neontal period or 21 days after enrollment), two does of oral azithromycin spaced 21 days apart, or two doses of placebo to evalute if azithromycin improves nutritional outcome and reduces infectious burden among neonates aged 1-27 days who are either low birthweight (<2500 g at birth) or underweight (weight-for-age Z-score < -2 at enrollment). The primary outcome will be weight-for-age Z-score at 6 months of age compared between arms. The investigators anticipate that the results of this study will provide definitive evidence on azithromycin as an early intervention for low birthweight/underweight neonates, who are at the highest risk of adverse outcomes.

Description:

The Vitality in Infants Via Azithromycin for Neonates Trial (VIVANT) is a proposed 1:1:1:1 randomized placebo-controlled trial to determine whether a single oral dose of azithromycin (20 mg/kg) administered either in the early or late neonatal/early infancy period is effective for improving infant growth outcomes, and if there is additional benefit of administration of a second dose of azithromycin 21 days after the first dose (Figure 2). This intervention schedule will allow for several questions related to azithromycin administration in neonates to be answered efficiently, including:

1. A single oral azithromycin dose compared to placebo, administered either earlier or later during the neonatal period or early infancy.

2. Two oral doses of azithromycin spaced 21 days apart compared to placebo.

3. Two oral doses of azithromycin compared to a single oral dose of azithromycin, which would allow for determination of any dose-dependent effects.

4. An early dose of azithromycin compared to a later dose of azithromycin, which may be beneficial if administration of azithromycin earlier during the neonatal period increases risk of IHPS
