NCT02047981

Brief Summary

Our long-term goal is to more precisely define the role of mass azithromycin treatments as an intervention for reducing childhood mortality. We propose a single multi-site (multi-country), cluster-randomized trial comparing communities randomized to oral azithromycin with those randomized to placebo. We hypothesize that mass azithromycin treatments will reduce childhood mortality.

Outcome Measures

Primary Outcomes (2)

  • All-cause Mortality Rate in Children Aged 1-60 Months

    This is a single multi-site trial, with each country as a secondary analysis. Also, an interim analysis of efficacy and futility will be conducted according to a pre-specified plan in the Statistical Analysis Plan.

    24 Months

  • All-cause Mortality Rate in Children Aged 1-60 Months

    This was a pre-specified contingency study in Niger only in which all communities were treated with mass azithromycin during the third year of the study following the primary 24-month endpoint.

    36 months

Secondary Outcomes (5)

  • Cause-specific Mortality Rate in Children Aged 1-60 Months, as Assessed From Verbal Autopsy (Niger Only)

    24 Months

  • Cost-effectiveness of Mass Azithromycin Administration, Per Averted Childhood Death

    24 months

  • All-cause and Cause-specific Health Clinic Visits in 1-60 Month-old Children

    24 months

  • Cause-specific Mortality Rate in Children Aged 1-60 Months, as Assessed From Verbal Autopsy (Tanzania Only)

    24 Months

  • Cause-specific Mortality Rate in Children Aged 1-60 Months, as Assessed From Verbal Autopsy (Malawi Only)

    24 Months

Study Arms (2)

Biannual mass oral azithromycin

ACTIVE COMPARATOR

Comparison of childhood mortality in communities randomized to azithromycin versus communities randomized to placebo. Children aged 1 month to 60 months per community will be offered weight or height-based, directly observed, oral azithromycin suspension every 6 months for 2 years. In Niger during year 3, all communities will be offered azithroymcin.

Drug: Azithromycin

Biannual mass oral placebo

PLACEBO COMPARATOR

Comparison of childhood mortality in communities randomized to azithromycin versus communities randomized to placebo. Children aged 1 month to 60 months per community will be offered weight or height-based, directly observed, oral placebo every 6 months for 2 years In Niger during year 3, all communities will be offered azithroymcin.

Drug: Placebo

Interventions

Children aged 1 month to 60 months per community will be offered weight or height-based, directly observed, oral azithromycin suspension every 6 months for 2 years. In Niger during year 3, all communities will be offered azithroymcin.

Also known as: Zithromax
Biannual mass oral azithromycin

Children aged 1 month to 60 months per community will be offered weight or height-based, directly observed, oral placebo every 6 months for 2 years. In Niger during year 3, all communities will be offered azithroymcin.

Biannual mass oral placebo
