Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The last decade has witnessed an important reduction of the mortality in children under 5 years but such reduction has not impacted in neonates. Mortality in neonates contributes 40% of all deaths occurring in children below 5 years of age.

Severe bacterial disease is among the leading causes of neonatal deaths. Bacterial disease follows bacterial infection. Individuals can be infected without developing disease (carriage stage) but infection is needed to subsequently develop disease. In sub-Saharan Africa, bacterial carriage (i.e. in the birth canal and/or nasopharyngeal tract) is very common in all age groups, with the consequence that occurrence of bacterial disease is one of the highest in the world.

Newborns can be infected during labour - when passing through the birth canal - and during the first days/weeks of life, as a consequence of the close physical contact with the mother, if the latter carries bacteria in the nasopharyngeal tract.

If the mother is an important source of bacterial infection to the newborn, treating mothers with a powerful antibiotic during labour should decrease bacterial carriage and therefore diminish the risk of bacterial transmission to the newborn during the first days/weeks of life, which should in turn result in the lower occurrence of severe bacterial disease and hence lower mortality.

The purpose of this trial is to evaluate the impact of a single oral dose of azithromycin given to women in labour on bacterial carriage of the newborn as well as the women during the first month after delivery.

The investigators have selected an antibiotic (azithromycin) that in sub-Saharan Africa has already shown both a strong impact on bacterial nasopharyngeal carriage and on all-cause mortality when administered to everybody in a community (mass drug administration). This specific antibiotic has several advantages for being deployable as a simple intervention in rural Africa, i.e. it requires a single oral administration, it has no special storage requirements and it has the potential to eliminate many of the bacteria commonly causing severe disease in newborn.

This clinical trial will be conducted in a peri-urban health facility in Western Gambia. If an impact is shown, the next step would be to conduct a larger study aiming at establishing if the intervention, implemented at a lower level of care (most African women deliver at home assisted by traditional birth assistants), decreases the occurrence of neonatal bacterial disease
