About
The double blind randomized controlled trial will assess the efficacy of oral azithromycin administered to pregnant women and/or infants during routine care in preventing stillbirths and mortality through 6-12 months of age in Mali, West Africa, where rates of infant and under five mortality are among the highest in the world.
Full description
This trial will assess the efficacy of oral azithromycin given during routine health care visits in preventing stillbirths and mortality through 6-12 months of age in Mali, West Africa, where rates of infant and under five mortality are among the highest in the world. Using an individually randomized placebo-controlled double-masked trial design, pregnant women will receive a single dose of oral azithromycin or placebo at their second and/or third trimester antenatal care visits and during labor, and to infants at their DPT-1 and DPT-3 vaccination visits, which occur at approximately 6 and 14 weeks of age, respectively. The two co-primary outcomes are (1A) a composite outcome of stillbirths and mortality through 6-12 months of age and (1B) mortality between 6 weeks and 6-12 months of age. The study sample size is powered to detect a 20% relative reduction in both of the two co-primary outcomes. The study is designed to inform policymakers regarding the effectiveness of azithromycin for the prevention of stillbirth and infant mortality in both urban and rural parts of the country when administered during routine antenatal and intrapartum care and infant immunization visits. To achieve this aim, three cohorts will be enrolled: a mother-infant cohort in a rural part of the country with infant mortality rates that are higher than the national average, a supplemental infant-only cohort enrolled form the same rural communities, and third urban mother-infant cohort residing in Bamako, Mali's capital. Sub studies designed to elucidate the protective mechanisms of azithromycin treatment will be embedded within the larger study and will be added in the future.

Infants attending routine immunization visits at eligible health facilities whose mothers were not enrolled in the study will be eligible for enrollment in the supplemental infant cohort within the rural study cohort with the following inclusion criteria:
- Infant is <12 mo attending a DTP-1 routine vaccination visit at a participating health facility.
- Parent or guardian is able to understand and comply with planned study procedures.
- Parent or guardian has provided informed consent prior to initiation of any study procedures.
- Parent or guardian intends to reside in the study area until participant is at least 12 months old.
Exclusion criteria
- Allergy to macrolides or azalides.
- Any condition that, in the opinion of the investigator, might compromise the well-being of the participant or compliance with study procedures.
- Medical treatment that requires administration of azithromycin (this can be a temporary exclusion if the drug is later discontinued).
